    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: Today's regulations (Phase II) expand the existing National 
    Pollutant Discharge Elimination System (NPDES) storm water program 
    (Phase I) to address storm water discharges from small municipal 
    separate storm sewer systems (MS4s) (those serving less than 100,000 
    persons) and construction sites that disturb one to five acres. 
    Although these sources are automatically designated by today's rule, 
    the rule allows for the exclusion of certain sources from the national 
    program based on a demonstration of the lack of impact on water 
    quality, as well as the inclusion of others based on a higher 
    likelihood of localized adverse impact on water quality. Today's 
    regulations also exclude from the NPDES program storm water discharges 
    from industrial facilities that have ``no exposure'' of industrial 
    activities or materials to storm water. Finally, today's rule extends 
    from August 7, 2001 until March 10, 2003 the deadline by which certain 
    industrial facilities owned by small MS4s must obtain coverage under an 
    NPDES permit. This rule establishes a cost-effective, flexible approach 
    for reducing environmental harm by storm water discharges from many 
    point sources of storm water that are currently unregulated.
        EPA believes that the implementation of the six minimum measures 
    identified for small MS4s should significantly reduce pollutants in 
    urban storm water compared to existing levels in a cost-effective 
    manner. Similarly, EPA believes that implementation of Best Management 
    Practices (BMP) controls at small construction sites will also result 
    in a significant reduction in pollutant discharges and an improvement 
    in surface water quality. EPA believes this rule will result in 
    monetized financial, recreational and health benefits, as well as 
    benefits that EPA has been unable to monetize. Expected benefits 
    include reduced scouring and erosion of streambeds, improved aesthetic 
    quality of waters, reduced eutrophication of aquatic systems, benefit 
    to wildlife and endangered and threatened species, tourism benefits, 
    biodiversity benefits and reduced costs for siting reservoirs. In 
    addition, the costs of industrial storm water controls will decrease 
    due to the exclusion of storm water discharges from facilities where 
    there is ``no exposure'' of storm water to industrial activities and 
    materials.
    
    DATES: This regulation is effective on February 7, 2000. The 
    incorporation by reference of the rainfall erosivity factor publication 
    listed in the rule is approved by the Director of the Federal Register 
    as of February 7, 2000. For judicial review purposes, this final rule 
    is promulgated as of 1:00 p.m. Eastern Standard Time, on December 22, 
    1999 as provided in 40 CFR 23.2.

    I. Background
    
    A. Proposed Rule and Pre-Proposal Outreach
    
        On January 9, 1998 (63 FR 1536), EPA proposed to expand the 
    National Pollutant Discharge Elimination System (NPDES) storm water 
    program to include storm water discharges from municipal separate storm 
    sewer systems (MS4s) and construction sites that were smaller than 
    those previously included in the program. The proposal also addressed 
    industrial sources that have ``no exposure'' of industrial activities 
    and materials to storm water. Today, EPA is promulgating a final rule 
    to implement most of the proposed revisions with minor changes based on 
    public comments received on the proposal. Today's final rule also 
    extends the deadline by which certain industrial facilities operated by 
    municipalities of less than 100,000 population must be covered by a 
    NPDES permit; the deadline is changed from August 7, 2001 until March 
    10, 2003.
        In 1972, Congress amended the Federal Water Pollution Control Act 
    (commonly referred to as the Clean Water Act (CWA)) to prohibit the 
    discharge of any pollutant to waters of the United States from a point 
    source unless the discharge is authorized by an NPDES permit. The NPDES 
    program is a program designed to track point sources and require the 
    implementation of the controls necessary to minimize the discharge of 
    pollutants. Initial efforts to improve water quality under the NPDES 
    program primarily focused on reducing pollutants in industrial process 
    wastewater and municipal sewage. These discharge sources were easily 
    identified as responsible for poor, often drastically degraded, water 
    quality conditions.
        As pollution control measures for industrial process wastewater and 
    municipal sewage were implemented and refined, it became increasingly 
    evident that more diffuse sources of water pollution were also 
    significant causes of water quality impairment. Specifically, storm 
    water runoff draining large surface areas, such as agricultural and 
    urban land, was found to be a major cause of water quality impairment, 
    including the nonattainment of designated beneficial uses.
        In 1987, Congress amended the CWA to require implementation, in two 
    phases, of a comprehensive national program for addressing storm water 
    discharges. The first phase of the program, commonly referred to as 
    ``Phase I,'' was promulgated on November 16, 1990 (55 FR 47990). Phase 
    I requires NPDES permits for storm water discharge from a large number 
    of priority sources including municipal separate storm sewer systems 
    (``MS4s'') generally serving populations of 100,000 or more and several 
    categories of industrial activity, including construction sites that 
    disturb five or more acres of land.
        Today's rule, which is the second phase of the storm water program, 
    expands the existing program to include discharges of storm water from 
    smaller municipalities in urbanized areas and from construction sites 
    that disturb between one and five acres of land. Today's rule allows 
    certain sources to be excluded from the national program based on a 
    demonstrable lack of impact on water quality. The rule also allows 
    other sources not automatically regulated on a national basis to be 
    designated for inclusion based on increased likelihood for localized 
    adverse impact on water quality.
    
    [[Page 68724]]
    
    Today's rule also conditionally excludes storm water discharges from 
    industrial facilities that have ``no exposure'' of industrial 
    activities or materials to storm water. Today's rule and the effort 
    that led to its development are commonly referred to as ``Phase II.'' 
    On August 7, 1995, EPA promulgated a final rule that required 
    facilities to be regulated under Phase II to apply for a NPDES permit 
    by August 7, 2001, unless the NPDES permitting authority designates 
    them as requiring a permit by an earlier date. (60 FR 40230). That rule 
    is referred to as ``the Interim Phase II Rule.'' Today's rule replaces 
    the Interim Phase II rule.
        EPA performed extensive outreach and worked with a variety of 
    stakeholders prior to proposing today's rule. On September 9, 1992, EPA 
    published a notice requesting information and public comment on how to 
    prepare regulations under CWA section 402(p)(6) (see 57 FR 41344). The 
    notice identified three sets of issues associated with developing new 
    NPDES storm water regulations: (1) How should EPA identify unregulated 
    sources of storm water to protect water quality, (2) what types of 
    control strategies should EPA develop for these sources, and (3) what 
    are appropriate deadlines for implementing new requirements. The notice 
    recognized that potential sources for coverage under the section 
    402(p)(6) regulations would fall into two main categories: municipal 
    separate storm sewer systems and individual (commercial and 
    residential) sources. EPA received more than 130 comments on the 
    September 9, 1992, notice. For further discussion of the comments 
    received, see Storm Water Discharges Potentially Addressed by Phase II 
    of the National Pollutant Discharge Elimination System: Report to 
    Congress (EPA, 1995a), pp. 1-21 to 1-22, and Appendix J (which provides 
    a detailed summary of the comments received as they relate to the 
    specific issues raised in the notice).
        In early 1993, the Rensselaerville Institute and EPA held public 
    and expert meetings to assist in developing and analyzing options for 
    identifying unregulated sources and possible controls. The report on 
    the 1993 meetings identified two options that were favored by the 
    various groups that participated. One option was a program that allowed 
    States to select sources to be controlled in a manner consistent with 
    criteria developed by EPA. A second option was a tiered approach under 
    which EPA would select high priority sources for control by NPDES 
    permits and States would select other sources for control under a State 
    water quality program other than the NPDES program. For additional 
    details see the ``Report on the EPA Storm Water Management Program 
    (Rensselaerville Study),'' Appendix I of Storm Water Discharges 
    Potentially Addressed by Phase II of the National Pollutant Discharge 
    Elimination System: Report to Congress (EPA, 1995a).
        EPA also conducted outreach with representatives of small entities 
    in conjunction with the convening of a Small Business Advocacy Review 
    Panel under the Small Business Regulatory Enforcement Fairness Act 
    (SBREFA). This process is discussed in section IV.E of today's 
    preamble. For additional background see the discussion in the preamble 
    to the proposal for today's rule.
        To assist EPA by providing advice and recommendations regarding the 
    urban municipal wet weather water pollution control program, EPA 
    established the Urban Wet Weather Flows Federal Advisory Committee 
    (hereinafter, ``FACA Committee'') under the Federal Advisory Committee 
    Act (FACA). The Office of Management and Budget approved the charter 
    for the FACA Committee on March 10, 1995. The FACA Committee provided a 
    forum for identifying and addressing issues associated with water 
    quality impacts from storm water sources.
        The FACA Committee established two subcommittees: the Storm Water 
    Phase II FACA Subcommittee and the Sanitary Sewer Overflows (SSOs) FACA 
    Subcommittee. Consistent with the requirements of FACA, the membership 
    of both the FACA Committee and the subcommittees was balanced among 
    EPA's various outside stakeholder interests, including representatives 
    from municipalities, States, Indian Tribes, EPA, industrial and 
    commercial sectors, agriculture, and environmental and public interest 
    groups.
        The Storm Water Phase II FACA Subcommittee (``Subcommittee'') met 
    fourteen times between September 1995 and June 1998. The 32 
    Subcommittee members discussed possible regulatory frameworks at these 
    meetings as well as during numerous other meetings and conference 
    calls. Members of the FACA Committee provided views regarding the 
    development of the ``no exposure'' provision and other provisions in 
    drafts of the Phase II rule. EPA provided Subcommittee members with 
    four successive drafts of the proposed rule and preamble, outlines of 
    the rule, summaries of the written comments received on each draft, and 
    documents identifying the changes made to each draft. In the course of 
    providing input to the Committee, individual Subcommittee members 
    provided significant input and advice that EPA considered in the 
    context of public comments received. Ultimately, the Subcommittee did 
    not provide a written report back to the FACA Committee, and the FACA 
    Committee did not provide written advice and recommendations to EPA. 
    The Agency, therefore, did not rely on group recommendations in 
    developing today's rule, but does consider the process to have resulted 
    in important public outreach.
    
    B. Water Quality Concerns/Environmental Impact Studies and Assessments
    
        Storm water runoff from lands modified by human activities can harm 
    surface water resources and, in turn, cause or contribute to an 
    exceedance of water quality standards by changing natural hydrologic 
    patterns, accelerating stream flows, destroying aquatic habitat, and 
    elevating pollutant concentrations and loadings. Such runoff may 
    contain or mobilize high levels of contaminants, such as sediment, 
    suspended solids, nutrients (phosphorous and nitrogen), heavy metals 
    and other toxic pollutants, pathogens, toxins, oxygen-demanding 
    substances (organic material), and floatables (U.S. EPA. 1992. 
    Environmental Impacts of Storm Water Discharges: A National Profile. 
    EPA 841-R-92-001. Office of Water. Washington, DC). After a rain, storm 
    water runoff carries these pollutants into nearby streams, rivers, 
    lakes, estuaries, wetlands, and oceans. The highest concentrations of 
    these contaminants often are contained in ``first flush'' discharges, 
    which occur during the first major storm after an extended dry period 
    (Schueler, T.R. 1994. ``First Flush of Stormwater Pollutants 
    Investigated in Texas.'' Note 28. Watershed Protection Techniques 
    1(2)). Individually and combined, these pollutants impair water 
    quality, threatening designated beneficial uses and causing habitat 
    alteration or destruction.
        Uncontrolled storm water discharges from areas of urban development 
    and construction activity negatively impact receiving waters by 
    changing the physical, biological, and chemical composition of the 
    water, resulting in an unhealthy environment for aquatic organisms, 
    wildlife, and humans. The following sections discuss the studies and 
    data that address and support this finding.
        Although water quality problems also can occur from agricultural

    concern is statutorily exempted from regulation as a point source under 
    the Clean Water Act and is not discussed here. (See CWA section 
    502(14)). Other storm water sources not specifically identified in the 
    regulations may be of concern in certain areas and can be addressed on 
    a case-by-case (or category-by-category) basis through the NPDES 
    designation authority preserved by CWA section 402(p)(2)(6), as well as 
    today's rule.
    1. Urban Development
        Urbanization alters the natural infiltration capability of the land 
    and generates a host of pollutants that are associated with the 
    activities of dense populations, thus causing an increase in storm 
    water runoff volumes and pollutant loadings in storm water discharged 
    to receiving waterbodies (U.S. EPA, 1992). Urban development increases 
    the amount of impervious surface in a watershed as farmland, forests, 
    and meadowlands with natural infiltration characteristics are converted 
    into buildings with rooftops, driveways, sidewalks, roads, and parking 
    lots with virtually no ability to absorb storm water. Storm water and 
    snow-melt runoff wash over these impervious areas, picking up 
    pollutants along the way while gaining speed and volume because of 
    their inability to disperse and filter into the ground. What results 
    are storm water flows that are higher in volume, pollutants, and 
    temperature than the flows in less impervious areas, which have more 
    natural vegetation and soil to filter the runoff (U.S. EPA, 1997. 
    Urbanization and Streams: Studies of Hydrologic Impacts. EPA 841-R-97-
    009. Office of Water. Washington, DC).
        Studies reveal that the level of imperviousness in an area strongly 
    correlates with the quality of the nearby receiving waters. For 
    example, a study in the Puget Sound lowland ecoregion found that when 
    the level of basin development exceeded 5 percent of the total 
    impervious area, the biological integrity and physical habitat 
    conditions that are necessary to support natural biological diversity 
    and complexity declined precipitously (May, C.W., E.B. Welch, R.R. 
    Horner, J.R. Karr, and B.W. May. 1997. Quality Indices for Urbanization 
    Effects in Puget Sound Lowland Streams, Technical Report No. 154. 
    University of Washington Water Resources Series). Research conducted in 
    numerous geographical areas, concentrating on various variables and 
    employing widely different methods, has revealed a similar conclusion: 
    stream degradation occurs at relatively low levels of imperviousness, 
    such as 10 to 20 percent (even as low as 5 to 10 percent according to 
    the findings of the Washington study referenced above) (Schueler, T.R. 
    1994. ``The Importance of Imperviousness.'' Watershed Protection 
    Techniques 1(3); May, C., R.R. Horner, J.R. Karr, B.W. Mar, and E.B. 
    Welch. 1997. ``Effects Of Urbanization On Small Streams In The Puget 
    Sound Lowland Ecoregion.'' Watershed Protection Techniques 2(4); Yoder, 
    C.O., R.J. Miltner, and D. White. 1999. ``Assessing the Status of 
    Aquatic Life Designated Uses in Urban and Suburban Watersheds.'' In 
    Proceedings: National Conference on Retrofits Opportunities in Urban 
    Environments. EPA 625-R-99-002, Washington, DC; Yoder, C.O and R.J. 
    Miltner. 1999. ``Assessing Biological Quality and Limitations to 
    Biological Potential in Urban and Suburban Watersheds in Ohio.'' In 
    Comprehensive Stormwater & Aquatic Ecosystem Management Conference 
    Papers, Auckland, New Zealand). Furthermore, research has indicated 
    that few, if any, urban streams can support diverse benthic communities 
    at imperviousness levels of 25 percent or more. An area of medium 
    density single family homes can be anywhere from 25 percent to nearly 
    60 percent impervious, depending on the design of the streets and 
    parking (Schueler, 1994).
        In addition to impervious areas, urban development creates new 
    pollution sources as population density increases and brings with it 
    proportionately higher levels of car emissions, car maintenance wastes, 
    pet waste, litter, pesticides, and household hazardous wastes, which 
    may be washed into receiving waters by storm water or dumped directly 
    into storm drains designed to discharge to receiving waters. More 
    people in less space results in a greater concentration of pollutants 
    that can be mobilized by, or disposed into, storm water discharges from 
    municipal separate storm sewer systems. A modeling system developed for 
    the Chesapeake Bay indicated that contamination of the Bay and its 
    tributaries from runoff is comparable to, if not greater than, 
    contamination from industrial and sewage sources (Cohn-Lee, R. and D. 
    Cameron. 1992. ``Urban Stormwater Runoff Contamination of the 
    Chesapeake Bay: Sources and Mitigation.'' The Environmental 
    Professional, Vol. 14).
    a. Large-Scale Studies and Assessments
        In support of today's regulatory designation of MS4s in urbanized 
    areas, the Agency relied on broad-based assessments of urban storm 
    water runoff and related water quality impacts, as well as more site-
    specific studies. The first national assessment of urban runoff 
    characteristics was completed for the Nationwide Urban Runoff Program 
    (NURP) study (U.S. EPA. 1983. Results of the Nationwide Urban Runoff 
    Program, Volume 1--Final Report. Office of Water. Washington, D.C.). 
    The NURP study is the largest nationwide evaluation of storm water 
    discharges, which includes adverse impacts and sources, undertaken to 
    date.
        EPA conducted the NURP study to facilitate understanding of the 
    nature of urban runoff from residential, commercial, and industrial 
    areas. One objective of the study was to characterize the water quality 
    of discharges from separate storm sewer systems that drain residential, 
    commercial, and light industrial (industrial parks) sites. Storm water 
    samples from 81 residential and commercial properties in 22 urban/
    suburban areas nationwide were collected and analyzed during the 5-year 
    period between 1978 and 1983. The majority of samples collected in the 
    study were analyzed for eight conventional pollutants and three heavy 
    metals.
        Data collected under the NURP study indicated that discharges from 
    separate storm sewer systems draining runoff from residential, 
    commercial, and light industrial areas carried more than 10 times the 
    annual loadings of total suspended solids (TSS) than discharges from 
    municipal sewage treatment plants that provide secondary treatment. The 
    NURP study also indicated that runoff from residential and commercial 
    areas carried somewhat higher annual loadings of chemical oxygen demand 
    (COD), total lead, and total copper than effluent from secondary 
    treatment plants. Study findings showed that fecal coliform counts in 
    urban runoff typically range from tens to hundreds of thousands per 
    hundred milliliters of runoff during warm weather conditions, with the 
    median for all sites being around 21,000/100 ml. This is generally 
    consistent with studies that found that fecal coliform mean values 
    range from 1,600 coliform fecal units (CFU)/100 ml to 250,000 cfu/100 
    ml (Makepeace, D.K., D.W. Smith, and S.J. Stanley. 1995. ``Urban Storm 
    Water Quality: Summary of Contaminant Data.'' Critical Reviews in 
    Environmental Science and Technology 25(2):93-139). Makepeace, et al., 
    summarized ranges of contaminants from storm water, including physical 
    contaminants such as total solids (76--36,200 mg/L) and copper (up to 
    1.41 mg/L); organic chemicals; organic compounds, such as oil and 
    grease (up to 110 mg/L); and microorganisms.
    
    [[Page 68726]]
    
        Monitoring data summarized in the NURP study provided important 
    information about urban runoff from residential, commercial, and light 
    industrial areas. The study concluded that the quality of urban runoff 
    can be affected adversely by several sources of pollution that were not 
    directly evaluated in the study, including illicit discharges, 
    construction site runoff, and illegal dumping. Data from the NURP study 
    were analyzed further in the U.S. Geological Survey (USGS) Urban Storm 
    Water Data Base for 22 Metropolitan Areas Throughout the United States 
    study (Driver, N.E., M.H. Mustard, R.B. Rhinesmith, and R.F. 
    Middleburg. 1985. U.S. Geological Survey Urban Storm Water Data Base 
    for 22 Metropolitan Areas Throughout the United States. Report No. 85-
    337 USGS. Lakewood, CO). The USGS report summarized additional 
    monitoring data compiled during the mid-1980s, covering 717 storm 
    events at 99 sites in 22 metropolitan areas and documented problems 
    associated with metals and sediment concentrations in urban storm water 
    runoff. More recent reports have confirmed the pollutant concentration 
    data collected in the NURP study (Marsalek, J. 1990. ``Evaluation of 
    Pollutant Loads from Urban Nonpoint Sources.'' Wat. Sci. Tech. 22(10/
    11):23-30; Makepeace, et al., 1995).
        Commenters argued that the NURP study does not support EPA's 
    contention that urban activities significantly jeopardize attainment of 
    water quality standards. One commenter argued that the NURP study and 
    the 1985 USGS study are seriously out of date. Because they were issued 
    10 years or more before the implementation of the current storm water 
    permit program, the data in those reports do not reflect conditions 
    that exist after implementation of permits issued by authorized States 
    and EPA for storm water from construction sites, large municipalities, 
    and industrial activities.
        In response, EPA notes that it is not relying solely on the NURP 
    study to describe current water quality impairment. Rather, EPA is 
    citing NURP as a source of data on typical pollutant concentrations in 
    urban runoff. Recent studies have not found significantly different 
    pollutant concentrations in urban runoff when compared to the original 
    NURP data (see Makepeace, et al., 1995; Marsalek, 1990; and Pitt, et 
    al., 1995).
        America's Clean Water--the States' Nonpoint Source Assessment 
    (Association of State and Interstate Water Pollution Control 
    Administrators (ASIWPCA). 1985. America's Clean Water--The States' 
    Nonpoint Source Assessment. Prepared in cooperation with the U.S. EPA, 
    Office of Water, Washington, DC), a comprehensive study of diffuse 
    pollution sources conducted under the sponsorship of the Association of 
    State and Interstate Water Pollution Control Administrators (ASIWPCA) 
    and EPA revealed that 38 States reported urban runoff as a major cause 
    of designated beneficial use impairment and 21 States reported storm 
    water runoff from construction sites as a major cause of beneficial use 
    impairment. In addition, the 1996 305(b) Report (U.S. EPA. 1998. The 
    National Water Quality Inventory, 1996 Report to Congress. EPA 841-R-
    97-008. Office of Water. Washington, DC), provides a national 
    assessment of water quality based on biennial reports submitted by the 
    States as required under CWA section 305(b) of the CWA. In the CWA 
    305(b) reports, States, Tribes, and Territories assess their individual 
    water quality control programs by examining the attainment or 
    nonattainment of the designated uses assigned to their rivers, lakes, 
    estuaries, wetlands, and ocean shores. A designated use is the legally 
    applicable use specified in a water quality standard for a watershed, 
    waterbody, or segment of a waterbody. The designated use is the 
    desirable use that the water quality should support. Examples of 
    designated uses include drinking water supply, primary contact 
    recreation (swimming), and aquatic life support. Each CWA 305(b) report 
    indicates the assessed fraction of a State's waters that are fully 
    supporting, partially supporting, or not supporting designated 
    beneficial uses.
        In their reports, States, Tribes, and Territories first identified 
    and then assigned the sources of water quality impairment for each 
    impaired waterbody using the following categories: industrial, 
    municipal sewage, combined sewer overflows, urban runoff/storm sewers, 
    agricultural, silvicultural, construction, resource extraction, land 
    disposal, hydrologic modification, and habitat modification. The 1996 
    Inventory, based on a compilation of 60 individual 305(b) reports 
    submitted by States, Tribes, and Territories, assessed the following 
    percentages of total waters nationwide: 19 percent of river and stream 
    miles; 40 percent of lake, pond, and reservoir acres; 72 percent of 
    estuary square miles; and 6 percent of ocean shoreline waters. The 1996 
    Inventory indicated that approximately 40 percent of the Nation's 
    assessed rivers, lakes, and estuaries are impaired. Waterbodies deemed 
    as ``impaired'' are either partially supporting designated uses or not 
    supporting designated uses.
        The 1996 Inventory also found urban runoff/discharges from storm 
    sewers to be a major source of water quality impairment nationwide. 
    Urban runoff/storm sewers were found to be a source of pollution in 13 
    percent of impaired rivers; 21 percent of impaired lakes, ponds, and 
    reservoirs; and 45 percent of impaired estuaries (second only to 
    industrial discharges). In addition, urban runoff was found to be the 
    leading cause of ocean impairment for those ocean miles surveyed.
        In addition, a recent USGS study of urban watersheds across the 
    United States has revealed a link between urban development and 
    contamination of local waterbodies. The study found the highest levels 
    of organic contaminants, known as polycyclic aromatic hydrocarbons 
    (PAHs) (products of combustion of wood, grass, and fossil fuels), in 
    the reservoirs of urbanized watersheds (U.S. Geological Survey (USGS). 
    1998. Research Reveals Link Between Development and Contamination in 
    Urban Watersheds. USGS news release. USGS National Water-Quality 
    Assessment Program).
        Urban storm water also can contribute significant amounts of 
    toxicants to receiving waters. Pitt, et. al. (1993), found heavy metal 
    concentrations in the majority of samples analyzed. Industrial or 
    commercial areas were likely to be the most significant pollutant 
    source areas (Pitt, R., R. Field, M. Lalor, M. Brown 1993. ``Urban 
    stormwater toxic pollutants: assessment, sources, and treatability'' 
    Water Environment Research, 67(3):260-75).
    b. Local and Watershed-Based Studies
        In addition to the large-scale nationwide studies and assessments, 
    a number of local and watershed-based studies from across the country 
    have documented the detrimental effects of urban storm water runoff on 
    water quality. A study of urban streams in Milwaukee County, Wisconsin, 
    found local streams to be highly degraded due primarily to urban 
    runoff, while three studies in the Atlanta, Georgia, region were 
    characterized as being ``the first documentation in the Southeast of 
    the strong negative relationship between urbanization and stream 
    quality that has been observed in other ecoregions'' (Masterson, J. and 
    R. Bannerman. 1994. ``Impacts of Storm Water Runoff on Urban Streams in 
    Milwaukee County, Wisconsin.'' Paper presented at National Symposium on 
    Water Quality: American Water Resources Association; Schueler, T.R. 
    1997. ``Fish Dynamics in Urban Streams Near Atlanta, Georgia.''
    
    [[Page 68727]]
    
    Technical Note 94. Watershed Protection Techniques 2(4)). Several other 
    studies, including those performed in Arizona (Maricopa County), 
    California (San Jose's Coyote Creek), Massachusetts (Green River), 
    Virginia (Tuckahoe Creek), and Washington (Puget Sound lowland 
    ecoregion), all had the same finding: runoff from urban areas greatly 
    impair stream ecology and the health of aquatic life; the more heavily 
    developed the area, the more detrimental the effects (Lopes, T. and K. 
    Fossum. 1995. ``Selected Chemical Characteristics and Acute Toxicity of 
    Urban Stormwater, Streamflow, and Bed Material, Maricopa County, 
    Arizona.'' Water Resources Investigations Report 95-4074. USGS; Pitt, 
    R. 1995. ``Effects of Urban Runoff on Aquatic Biota.'' In Handbook of 
    Ecotoxicology; Pratt, J. and R. Coler. 1979. ``Ecological Effects of 
    Urban Stormwater Runoff on Benthic Macroinvertebrates Inhabiting the 
    Green River, Massachusetts.'' Completion Report Project No. A-094.

    Amherst.; Schueler, T.R. 1997. ``Historical Change in a Warmwater Fish 
    Community in an Urbanizing Watershed.'' Technical Note 93. Watershed 
    Protection Techniques 2(4); May, C., R. Horner, J. Karr, B. Mar, and E. 
    Welch. 1997. ``Effects Of Urbanization On Small Streams In The Puget 
    Sound Lowland Ecoregion.'' Watershed Protection Techniques 2(4)).
        Pitt and others also described the receiving water effects on 
    aquatic organisms associated with urban runoff (Pitt, R.E. 1995. 
    ``Biological Effects of Urban Runoff Discharges'' In Stormwater Runoff 
    and Receiving Systems: Impact, Monitoring, and Assessment, ed. E.E 
    Herricks, Lewis Publishers; Crunkilton, R., J. Kleist, D. Bierman, J. 
    Ramcheck, and W. DeVita. 1999. ``Importance of Toxicity as a Factor 
    Controlling the Distribution of Aquatic Organisms in an Urban Stream.'' 
    In Comprehensive Stormwater & Aquatic Ecosystem Management Conference 
    Papers. Auckland, New Zealand).
        In Wisconsin, runoff samples were collected from streets, parking 
    lots, roofs, driveways, and lawns. Source areas were broken up into 
    residential, commercial, and industrial. Geometric mean concentration 
    data for residential areas included total solids of about 500-800 mg/L 
    from streets and 600 mg/L from lawns. Fecal coliform data from 
    residential areas ranged from 34,000 to 92,000 cfu/100 mL for streets 
    and driveways. Contaminant concentration data from commercial and 
    industrial source areas were lower for total solids and fecal coliform, 
    but higher for total zinc (Bannerman, R.T., D.W. Owens, R.B. Dods, and 
    N.J. Hornewer. 1993. ``Sources of Pollutants in Wisconsin Stormwater.'' 
    Wat. Sci. Tech. 28(3-5):241-59).
        Bannerman, et al. also found that streets contribute higher loads 
    of pollutants to urban storm water than any other residential 
    development source. Two small urban residential watersheds were 
    evaluated to determine that lawns and streets are the largest sources 
    of total and dissolved phosphorus in the basins (Waschbusch, R.J., W.R. 
    Selbig, and R.T. Bannerman. 1999. ``Sources of Phosphorus in Stormwater 
    and Street Dirt from Two Urban Residential Basins In Madison, 
    Wisconsin, 1994-95.'' Water Resources Investigations Report 99-4021. 
    U.S. Geological Survey). A number of other studies have indicated that 
    urban roadways often contain significant quantities of metal elements 
    and solids (Sansalone, J.J. and S.G. Buchberger. 1997. ``Partitioning 
    and First Flush of Metals in Urban Roadway Storm Water.'' ASCE Journal 
    of Environmental Engineering 123(2); Sansalone, J.J., J.M. Koran, J.A. 
    Smithson, and S.G. Buchberger. 1998. ``Physical Characteristics of 
    Urban Roadway Solids Transported During Rain Events'' ASCE Journal of 
    Environmental Engineering 124(5); Klein, L.A., M. Lang, N. Nash, and 
    S.L. Kirschner. 1974. ``Sources of Metals in New York City Wastewater''

    Quantity and Control of Pollution from Highway Runoff and 
    Construction.'' Research Report 1943-1. Center for Transportation 
    Research, University of Texas, Austin).
    c. Beach Closings/Advisories
        Urban wet weather flows have been recognized as the primary sources 
    of estuarine pollution in coastal communities. Urban storm water 
    runoff, sanitary sewer overflows, and combined sewer overflows have 
    become the largest causes of beach closings in the United States in the 
    past three years. Storm water discharges from urban areas not only pose 
    a threat to the ecological environment, they also can substantially 
    affect human health. A survey of coastal and Great Lakes communities 
    reports that in 1998, more than 1,500 beach closings and advisories 
    were associated with storm water runoff (Natural Resources Defense 
    Council. 1999. ``A Guide to Water Quality at Vacation Beaches'' New 
    York, NY). Other reports also document public health, shellfish bed, 
    and habitat impacts from storm water runoff, including more than 823 
    beach closings/advisories issued in 1995 and more than 407 beach 
    closing/advisories issued in 1996 due to urban runoff (Natural 
    Resources Defense Council. 1996. Testing the Waters Volume VI: Who 
    Knows What You're Getting Into. New York, NY; NRDC. 1997. Testing the 
    Waters Volume VII: How Does Your Vacation Beach Rate. New York, NY; 
    Morton, T. 1997. Draining to the Ocean: The Effects of Stormwater 
    Pollution on Coastal Waters. American Oceans Campaign, Santa Monica, 
    CA). The Epidemiological Study of Possible Adverse Health Effects of 
    Swimming in Santa Monica Bay (Haile, R.W., et. al. 1996. ``An 
    Epidemiological Study of Possible Adverse Health Effects of Swimming in 
    Santa Monica Bay.'' Final Report prepared for the Santa Monica Bay 
    Restoration Project) concluded that there is a 57 percent higher rate 
    of illness in swimmers who swim adjacent to storm drains than in 
    swimmers who swim more than 400 yards away from storm drains. This and 
    other studies document a relationship between gastrointestinal illness 
    in swimmers and water quality, the latter of which can be heavily 
    compromised by polluted storm water discharges.
    2. Non-Storm Water Discharges Through Municipal Storm Sewers
        Studies have shown that discharges from MS4s often include wastes 
    and wastewater from non-storm water sources. Federal regulations 
    (Sec. 122.26(b)(2)) define an illicit discharge as ``* * * any 
    discharge to an MS4 that is not composed entirely of storm water * * 
    *,'' with some exceptions. These discharges are ``illicit'' because 
    municipal storm sewer systems are not designed to accept, process, or 
    discharge such wastes. Sources of illicit discharges include, but are 
    not limited to: sanitary wastewater; effluent from septic tanks; car 
    wash, laundry, and other industrial wastewaters; improper disposal of 
    auto and household toxics, such as used motor oil and pesticides; and 
    spills from roadway and other accidents.
        Illicit discharges enter the system through either direct 
    connections (e.g., wastewater piping either mistakenly or deliberately 
    connected to the storm drains) or indirect connections (e.g., 
    infiltration into the MS4 from cracked sanitary systems, spills 
    collected by drain outlets, and paint or used oil dumped directly into 
    a drain). The result is untreated discharges that contribute high 
    levels of pollutants,
    
    [[Page 68728]]
    
    including heavy metals, toxics, oil and grease, solvents, nutrients, 
    viruses and bacteria into receiving waterbodies. The NURP study, 
    discussed earlier, found that pollutant levels from illicit discharges 
    were high enough to significantly degrade receiving water quality and 
    threaten aquatic, wildlife, and human health. The study noted 
    particular problems with illicit discharges of sanitary wastes, which 
    can be directly linked to high bacterial counts in receiving waters and 
    can be dangerous to public health.
        Because illicit discharges to MS4s can create severe widespread 
    contamination and water quality problems, several municipalities and 
    urban counties performed studies to identify and eliminate such 
    discharges. In Michigan, the Ann Arbor and Ypsilanti water quality 
    projects inspected 660 businesses, homes, and other buildings and 
    identified 14 percent of the buildings as having improper storm sewer 
    drain connections. The program assessment revealed that, on average, 60 
    percent of automobile-related businesses, including service stations, 
    automobile dealerships, car washes, body shops, and light industrial 
    facilities, had illicit connections to storm sewer drains. The program 
    assessment also showed that a majority of the illicit discharges to the 
    storm sewer system resulted from improper plumbing and connections, 
    which had been approved by the municipality when installed (Washtenaw 
    County Statutory Drainage Board. 1987. Huron River Pollution Abatement 
    Program).
        In addition, an inspection of urban storm water outfalls draining 
    into Inner Grays, Washington, indicated that 32 percent of these 
    outfalls had dry weather flows. Of these flows, 21 percent were 
    determined to have pollutant levels higher than the pollutant levels 
    expected in typical urban storm water runoff characterized in the NURP 
    study (U.S. EPA. 1993. Investigation of Inappropriate Pollutant Entries 
    Into Storm Drainage Systems--A User's Guide. EPA 600/R-92/238. Office 
    of Research and Development. Washington, DC). That same document 
    reports a study in Toronto, Canada, that found that 59 percent of 
    outfalls from the MS4 had dry-weather flows. Chemical tests revealed 
    that 14 percent of these dry-weather flows were determined to be 
    grossly polluted.
        Inflows from aging sanitary sewer collection systems are one of the 
    most serious illicit discharge-related problems. Sanitary sewer systems 
    frequently develop leaks and cracks, resulting in discharges of 
    pollutants to receiving waters through separate storm sewers. These 
    pollutants include sanitary waste and materials from sewer main 
    construction (e.g., asbestos cement, brick, cast iron, vitrified clay). 
    Municipalities have long recognized the reverse problem of storm water 
    infiltration into sanitary sewer collection systems; this type of 
    infiltration often disrupts the operation of the municipal sewage 
    treatment plant.
        The improper disposal of materials is another illicit discharge-
    related problem that can result in contaminated discharges from 
    separate storm sewer systems in two ways. First, materials may be 
    disposed of directly in a catch basin or other storm water conveyance. 
    Second, materials disposed of on the ground may either drain directly 
    to a storm sewer or be washed into a storm sewer during a storm event. 
    Improper disposal of materials to street catch basins and other storm 
    sewer inlets often occurs when people mistakenly believe that disposal 
    to such areas is an environmentally sound practice. Part of the 
    confusion may occur because some areas are served by combined sewer 
    systems, which are part of the sanitary sewer collection system, and 
    people assume that materials discharged to a catch basin will reach a 
    municipal sewage treatment plant. Materials that are commonly disposed 
    of improperly include used motor oil; household toxic materials; 
    radiator fluids; and litter, such as disposable cups, cans, and fast-
    food packages. EPA believes that there has been increasing success in 
    addressing these problems through initiatives such as storm drain 
    stenciling and recycling programs, including household hazardous waste 
    special collection days.
        Programs that reduce illicit discharges to separate storm sewers 
    have improved water quality in several municipalities. For example, 
    Michigan's Huron River Pollution Abatement Program found the 
    elimination of illicit connections caused a measurable improvement in 
    the water quality of the Washtenaw County storm sewers and the Huron 
    River (Washtenaw County Statutory Drainage Board, 1987). In addition, 
    an illicit detection and remediation program in Houston, Texas, has 
    significantly improved the water quality of Buffalo Bayou. Houston 
    estimated that illicit flows from 132 sources had a flow rate as high 
    as 500 gal/min. Sources of the illicit discharges included broken and 
    plugged sanitary sewer lines, illicit connections from sanitary lines 
    to storm sewer lines, and floor drain connections (Glanton, T., M.T. 
    Garrett, and B. Goloby. 1992. The Illicit Connection: Is It the 
    Problem? Wat. Env. Tech. 4(9):63-8).
    3. Construction Site Runoff
        Storm water discharges generated during construction activities can 
    cause an array of physical, chemical, and biological water quality 
    impacts. Specifically, the biological, chemical, and physical integrity 
    of the waters may become severely compromised. Water quality impairment 
    results, in part, because a number of pollutants are preferentially 
    absorbed onto mineral or organic particles found in fine sediment. The 
    interconnected process of erosion (detachment of the soil particles), 
    sediment transport, and delivery is the primary pathway for introducing 
    key pollutants, such as nutrients (particularly phosphorus), metals, 
    and organic compounds into aquatic systems (Novotny, V. and G. 
    Chesters. 1989. ``Delivery of Sediment and Pollutants from Nonpoint 
    Sources: A Water Quality Perspective.'' Journal of Soil and Water 
    Conservation, 44(6):568-76). Estimates indicate that 80 percent of the 
    phosphorus and 73 percent of the Kjeldahl nitrogen in streams is 
    associated with eroded sediment (U.S. Department of Agriculture. 1989. 
    ``The Second RCA Appraisal, Soil, Water and Related Resources on 
    Nonfederal Land in the United States, Analysis of Condition and 
    Trends.'' Cited in Fennessey, L.A.J., and A.R. Jarrett. 1994. ``The 
    Dirt in a Hole: a Review of Sedimentation Basins for Urban Areas and 
    Construction Sites.'' Journal of Soil and Water Conservation, 
    49(4):317-23).
        In watersheds experiencing intensive construction activity, the 
    localized impacts of water quality may be severe because of high 
    pollutant loads, primarily sediments. Siltation is the largest cause of 
    impaired water quality in rivers and the third largest cause of 
    impaired water quality in lakes (U.S. EPA, 1998). The 1996 305(b) 
    report also found that construction site discharges were a source of 
    pollution in: 6 percent of impaired rivers; 11 percent of impaired 
    lakes, ponds, and reservoirs; and 11 percent of impaired estuaries. 
    Introduction of coarse sediment (coarse sand or larger) or a large 
    amount of fine sediment is also a concern because of the potential of 
    filling lakes and reservoirs (along with the associated remediation 
    costs for dredging), as well as clogging stream channels (e.g., 
    Paterson, R.G., M.I. Luger, E.J. Burby, E.J. Kaiser, H.R. Malcolm, and 
    A.C. Beard. 1993. ``Costs and Benefits of Urban Erosion and Sediment 
    Control: North Carolina Experience.'' Environmental Management 
    17(2):167-78). Large inputs of coarse sediment into
    
    [[Page 68729]]
    
    stream channels initially will reduce stream depth and minimize habitat 
    complexity by filling in pools (U.S. EPA. 1991. Monitoring Guidelines 
    to Evaluate Effects of Forestry Activities on Streams in the Pacific 
    Northwest and Alaska. EPA 910/9-91-001. Seattle, WA). In addition, 
    studies have shown that stream reaches affected by construction 
    activities often extend well downstream of the construction site. For 
    example, between 4.8 and 5.6 kilometers of stream below construction 
    sites in the Patuxent River watershed were observed to be impacted by 
    sediment inputs (Fox, H.L. 1974. ``Effects of Urbanization on the 
    Patuxent River, with Special Emphasis on Sediment Transport, Storage, 
    and Migration.'' Ph.D. dissertation. Johns Hopkins University, 
    Baltimore, MD. As Cited in Klein, R.D. 1979. ``Urbanization and Stream 
    Quality Impairment.'' Water Resources Bulletin 15(4): 948-63).
        A primary concern at most construction sites is the erosion and 
    transport process related to fine sediment because rain splash, rills 
    (i.e., a channel small enough to be removed by normal agricultural 
    practices and typically less than 1-foot deep), and sheetwash encourage 
    the detachment and transport of this material to waterbodies (Storm 
    Water Quality Task Force. 1993. California Storm Water Best Management 
    Practice Handbooks--Construction Activity. Oakland, CA: Blue Print 
    Service). Construction sites also can generate other pollutants 
    associated with onsite wastes, such as sanitary wastes or concrete 
    truck washout.
        Although streams and rivers naturally carry sediment loads, erosion 
    from construction sites and runoff from developed areas can elevate 
    these loads to levels well above those in undisturbed watersheds. It is 
    generally acknowledged that erosion rates from construction sites are 
    much greater than from almost any other land use (Novotny, V. and H. 
    Olem. 1994. Water Quality: Prevention, Identification, and Management 
    of Diffuse Pollution. New York: Van Nostrand Reinhold). Results from 
    both field studies and erosion models indicate that erosion rates from 
    construction sites are typically an order of magnitude larger than row 
    crops and several orders of magnitude greater than rates from well-
    vegetated areas, such as forests or pastures (USDA. 1970. ``Controlling 
    Erosion on Construction Sites.'' Agriculture Information Bulletin, 
    Washington, DC; Meyer, L.D., W.H. Wischmeier, and W.H. Daniel. 1971. 
    ``Erosion, Runoff and Revegetation of Denuded Construction Sites.'' 
    Transactions of the ASAE 14(1):138-41; Owen, O.S. 1975. Natural 
    Resource Conservation. New York: MacMillan. As cited in Paterson, et 
    al., 1993).
        A recent review of the efficiency of sediment basins indicated that 
    inflows from 12 construction sites had a mean TSS concentration of 
    about 4,500 mg/L (Brown, W.E. 1997. ``The Limits of Settling.'' 
    Technical Note No. 83. Watershed Protection Techniques 2(3)). In 
    Virginia, suspended sediment concentrations from housing construction 
    sites were measured at 500-3,000 mg/L, or about 40 times larger than 
    the concentrations from already-developed urban areas (Kuo, C.Y. 1976. 
    ``Evaluation of Sediment Yields Due to Urban Development.'' Bulletin 
    No. 98. Virginia Water Resources Research Center, Virginia Polytechnic 
    Institute and State University, Blacksburg, VA).
        Similar impacts from storm water runoff have been reported in a 
    number of other studies. For example, Daniel, et al., monitored three 
    residential construction sites in southeastern Wisconsin and determined 
    that annual sediment yields were more than 19 times the yields from 
    agricultural areas (Daniel, T.C., D. McGuire, D. Stoffel, and B. 
    Miller. 1979. ``Sediment and Nutrient Yield from Residential 
    Construction Sites'' Journal of Environmental Quality 8(3):304-08). 
    Daniel, et al., identified total storm runoff, followed by peak storm 
    runoff, as the most influential factors controlling the sediment 
    loadings from residential construction sites. Daniel, et al., also 
    found that suspended sediment concentrations were 15,000-20,000 mg/L in 
    moderate events and up to 60,000 mg/L in larger events.
        Wolman and Schick (Wolman, M.G. and A.P. Schick. 1967. ``Effects of 
    Construction on Fluvial Sediment, Urban and Suburban Areas of 
    Maryland.'' Water Resources Research 3(2): 451-64) studied the impacts 
    of development on fluvial systems in Maryland and determined that 
    sediment yields in areas undergoing construction were 1.5 to 75 times 
    greater than detected in natural or agricultural catchments. The 
    authors summarize the potential impacts of construction on sediment 
    yields by stating that ``the equivalent of many decades of natural or 
    even agricultural erosion may take place during a single year from 
    areas cleared for construction'' (Wolman and Schick, 1967).
        A number of studies have examined the effects of road construction 
    on erosion rates and sediment yields. A highway construction project in 
    West Virginia disturbed only 4.2 percent of a 4.72-square-mile basin, 
    but resulted in a three-fold increase in suspended sediment yields 
    (Downs, S.C. and D.H. Appel. 1986. Progress Report on the Effects of 
    Highway Construction on Suspended-Sediment Discharge in the Coal River 
    and Trace Fork, West Virginia, 1975-81. USGS Water Resources 
    Investigations Report 84-4275. Charlestown, WV). During the largest 
    storm event, it was estimated that 80 percent of the sediment in the 
    stream originated from the construction site. As is often the case, the 
    increase in suspended sediment load could not be detected further 
    downstream, where the drainage area was more than 50 times larger (269 
    square miles).
        Another study evaluated the effect of 290 acres of highway 
    construction on watersheds ranging in size from 5 to 38 square miles. 
    Suspended sediment loads in the smallest watershed increased by 250 
    percent, and the estimated sediment yield from the construction area 
    was 37 tons/acre during a 2-year period (Hainly, R.A. 1980. The Effects 
    of Highway Construction on Sediment Discharge into Blockhouse Creek and 
    Stream Valley Run, Pennsylvania. USGS Water Resources Investigations 
    Report 80-68. Harrisburg, PA). A more recent study in Hawaii showed 
    that highway construction increased suspended sediment loads by 56 to 
    76 percent in three small (1 to 4 square mile) basins (Hill, B.R. 1996. 
    Streamflow and Suspended-Sediment Loads Before and During Highway 
    Construction, North Halawa, Haiku, and Kamooalii Drainage Basins, Oahu, 
    Hawaii, 1983-91. USGS Water Resources Investigations Report 96-4259. 
    Honolulu, HI). A 1970 study determined that sediment yields from 
    construction areas can be as much as 500 times the levels detected in 
    rural areas (National Association of Counties Research Foundation. 
    1970. Urban Soil Erosion and Sediment Control. Water Pollution Control 
    Research Series, Program #15030 DTL. Federal Water Quality 
    Administration, U.S. Department of Interior. Washington, DC)
        Yorke and Herb (Yorke, T.H., and W.J. Herb. 1978. Effects of 
    Urbanization on Streamflow and Sediment Transport in the Rock Creek and 
    Anacostia River Basins, Montgomery County, Maryland, 1962-74. USGS 
    Professional Paper 1003, Washington, DC) evaluated nine subbasins in 
    the Maryland portion of the Anacostia watershed for more than a decade 
    in an effort to define the impacts of changing land use/land cover on 
    sediment in runoff. Average annual suspended sediment yields for 
    construction sites ranged from 7 to 100 tons/acre. Storm water 
    discharges from construction sites that occur when the land area is 
    disturbed (and prior to
    
    [[Page 68730]]
    
    surface stabilization) can significantly impact designated uses. 
    Examples of designated uses include public water supply, recreation, 
    and propagation of fish and wildlife. The siltation process described 
    previously can threaten all three designated uses by (1) depositing 
    high concentrations of pollutants in public water supplies; (2) 
    decreasing the depth of a waterbody, which can reduce the volume of a 
    reservoir or result in limited use of a water body by boaters, 
    swimmers, and other recreational enthusiasts; and (3) directly 
    impairing the habitat of fish and other aquatic species, which can 
    limit their ability to reproduce.
        Excess sediment can cause a number of other problems for 
    waterbodies. It is associated with increased turbidity and reduced 
    light penetration in the water column, as well as more long-term 
    effects associated with habitat destruction and increased difficulty in 
    filtering drinking water. Numerous studies have examined the effect 
    that excess sediment has on aquatic ecosystems. For example, sediment 
    from road construction activity in Northern Virginia reduced aquatic 
    insect and fish communities by up to 85 percent and 40 percent, 
    respectively (Reed, J.R. 1997. ``Stream Community Responses to Road 
    Construction Sediments.'' Bulletin No. 97. Virginia Water Resources 
    Research Center, Virginia Polytechnic Institute, Blacksburg, VA. As 
    cited in Klein, R.D. 1990. A Survey of Quality of Erosion and Sediment 
    Control and Storm Water Management in the Chesapeake Bay Watershed. 
    Annapolis, MD: Chesapeake Bay Foundation). Other studies have shown 
    that fine sediment (fine sand or smaller) adversely affects aquatic 
    ecosystems by reducing light penetration, impeding sight-feeding, 
    smothering benthic organisms, abrading gills and other sensitive 
    structures, reducing habitat by clogging interstitial spaces within a 
    streambed, and reducing the intergravel dissolved oxygen by reducing 
    the permeability of the bed material (Everest, F.H., J.C. Beschta, K.V. 
    Scrivener, J.R. Koski, J.R. Sedell, and C.J. Cederholm. 1987. ``Fine 
    Sediment and Salmonid Production: A Paradox.'' Streamside Management: 
    Forestry and Fishery Interactions, Contract No. 57, Institute of Forest 
    Resources, University of Washington, Seattle, WA). For example, 4.8 and 
    5.6 kilometers of stream below construction sites in the Patuxent River 
    watershed in Maryland were found to have fine sediment amounts 15 times 
    greater than normal (Fox, 1974. As cited in Klein, 1979). Benthic 
    organisms in the streambed can be smothered by sediment deposits, 
    causing changes in aquatic flora and fauna, such as fish species 
    composition (Wolman and Schick, 1967). In addition, the primary cause 
    of coral reef degradation in coastal areas is attributed to land 
    disturbances and dredging activities due to urban development (Rogers, 
    C.S. 1990. ``Responses of Coral Reefs and Reef Organizations to 
    Sedimentation.'' Marine Ecology Progress Series, 62:185-202).
        EPA believes that the water quality impact from small construction 
    sites is as high as or higher than the impact from larger sites on a 
    per acre basis. The concentration of pollutants in the runoff from 
    smaller sites is similar to the concentrations in the runoff from 
    larger sites. The proportion of sediment that makes it from the 
    construction site to surface waters is likely the same for larger and 
    smaller construction sites in urban areas because the runoff from 
    either site is usually delivered directly to the storm drain network 
    where there is no opportunity for the sediment to be filtered out.
        The expected contribution of total sediment yields from small sites 
    depends, in part, on the extent to which erosion and sedimentation 
    controls are being applied. Because current storm water regulations are 
    more likely to require erosion and sedimentation controls on larger 
    sites in urban areas, smaller construction sites that lack such 
    programs are likely to contribute a disproportionate amount of the 
    total sediment from construction activities (MacDonald, L.H. 1997. 
    Technical Justification for Regulating Construction Sites 1-5 Acres in 
    Size. Unpublished report submitted to U.S. EPA, Washington, DC). 
    Smaller construction sites are less likely to have an effective plan to 
    control erosion and sedimentation, are less likely to properly 
    implement and maintain their plans, and are less likely to be inspected 
    (Brown, W. and D. Caraco. 1997. Controlling Storm Water Runoff 
    Discharges from Small Construction Sites: A National Review. Submitted 
    to Office of Wastewater Management, U.S. EPA, Washington, DC., by the 
    Center for Watershed Protection, Silver Spring, MD). The proportion of 
    sediment that makes it from the construction site to surface waters is 
    likely the same for larger and smaller construction sites in urban 
    areas because the runoff from either site is usually delivered directly 
    to the storm drain network, where there is no opportunity for the 
    sediment to be filtered out.
        To confirm its belief that sediment yields from small sites are as 
    high as or higher than the 20 to 150 tons/acre/year measured from 
    larger sites, EPA gave a grant to the Dane County, Wisconsin Land 
    Conservation Department, in cooperation with the USGS, to evaluate 
    sediment runoff from two small construction sites. The first was a 0.34 
    acre residential lot and the second was a 1.72 acre commercial office 
    development. Runoff from the sites was channeled to a single discharge 
    point for monitoring. Each site was monitored before, during, and after 
    construction.
        The Dane County study found that total solids concentrations from 
    these small sites are similar to total solids concentrations from 
    larger construction sites. Results show that for both of the study 
    sites, total solids and suspended solids concentrations were 
    significantly higher during construction than either before or after 
    construction. For example, preconstruction total solids concentrations 
    averaged 642 mg/L during the period when ryegrass was established, 
    active construction total solids concentrations averaged 2,788 mg/L, 
    and post-construction total solids concentrations averaged 132 mg/L (on 
    a pollutant load basis, this equaled 7.4 lbs preconstruction, 35 lbs 
    during construction, and 0.6 lbs post-construction for total solids). 
    While this site was not properly stabilized before construction, after 
    construction was complete and the site was stabilized, post-
    construction concentrations were more than 20 times less than during 
    construction. The results were even more dramatic for the commercial 
    site. The commercial site had one preconstruction event, which resulted 
    in total solids concentrations of 138 mg/L, while active construction 
    averaged more than 15,000 mg/L and post-construction averaged only 200 
    mg/L (on a pollutant load basis, this equaled 0.3 lbs preconstruction, 
    490 lbs during construction, and 13.4 lbs post-construction for total 
    solids). The active construction period resulted in more than 75 times 
    more sediment than either before or after construction (Owens, D.W., P. 
    Jopke, D.W. Hall, J. Balousek and A. Roa. 1999. ``Soil Erosion from 
    Small Construction Sites.'' Draft USGS Fact Sheet. USGS and Dane County 
    Land Conservation Department, WI). The total solids concentrations from 
    these small sites in Wisconsin are similar to total solids 
    concentrations from larger construction sites. For example, a study 
    evaluating the effects of highway construction in West Virginia found 
    that a small storm produced a sediment concentration of 7,520 mg/L 
    (Downs and Appel, 1986).
        One important aspect of small construction sites is the number of 
    small sites relative to larger construction sites
    
    [[Page 68731]]
    
    and total land area within the watershed. Brown and Caraco surveyed 219 
    local jurisdictions to assess erosion and sediment control (ESC) 
    programs. Seventy respondents provided data on the number of ESC 
    permits for construction sites smaller than 5 acres. In 27 cases (38 
    percent of the respondents), more than three-quarters of the permits 
    were for sites smaller than 5 acres; in another 18 cases (26 percent), 
    more than half of the permits were for sites smaller than 5 acres.
        In addition, data on the total acreage disturbed by smaller 
    construction sites have been collected recently in two States 
    (MacDonald, 1997). The most recent and complete data set is the listing 
    of the disturbed area for each of the 3,831 construction sites 
    permitted in North Carolina for 1994-1995 and 1995-1996. Nearly 61 
    percent of the sites that were 1 acre or larger were between 1.0 and 
    4.9 acres in size. This proportion was consistent between years. Data 
    showed that this range of sites accounted for 18 percent of the total 
    area disturbed by construction. The values showed very little variation 
    between the 2 years of data. The total disturbed area for all sites 
    over this 2-year period was nearly 33,000 acres, or about 0.1 percent 
    of the total area of North Carolina.
        EPA estimates that construction sites disturbing greater than 5 
    acres disturb 2.1-million acres of land (78.1 percent of the total) 
    while sites disturbing between 1 and 5 acres of land disturb 0.5-
    million acres of land (19.4 percent). The remaining sites on less than 
    1 acres of land disturb 0.07-million acres of land (only 2.5 percent of 
    the total). Given the high erosion rates associated with most 
    construction sites, small construction sites can be a significant 
    source of water quality impairment, particularly in small watersheds 
    that are undergoing rapid development. Exempting sites under 1 acre 
    will exclude only about 2.5 percent of acreage from program coverage, 
    but will exclude a far higher number of sites, approximately 25 
    percent.
        Several studies have determined that the most effective 
    construction runoff control programs rely on local plan review and 
    field enforcement (Paterson, R. G. 1994. ``Construction Practices: the 
    Good, the Bad, and the Ugly.'' Watershed Protection Techniques 1(3)). 
    In his review, Paterson suggests that, given the critical importance of 
    field implementation of erosion and sediment control programs and the 
    apparent shortcomings that exist, much more focus should be given to 
    plan implementation.
        Several commenters disputed the data presented in the proposed rule 
    for storm water discharges from smaller construction sites. One 
    commenter stated that EPA has not adequately explained the basis for 
    permitting construction activity down to 1 disturbed acre. Another 
    commenter stated that EPA did not present sufficient data on water 
    quality impacts from construction sites disturbing less than 5 acres.
        EPA believes that the data presented above sufficiently support 
    nationwide designation of storm water discharges from construction 
    activity disturbing more than 1 acre. Based on total disturbed land 
    area within a watershed, the cumulative effects of numerous small 
    construction sites can have impacts similar to those of larger sites in 
    a particular area. In addition, waivers for storm water discharges from 
    smaller construction activity will exclude sites not expected to impair 
    water quality. EPA will continue to collect water quality data on 
    construction site storm water runoff.
    
    C. Statutory Background
    
        In 1972, Congress enacted the CWA to prohibit the discharge of any 
    pollutant to waters of the United States from a point source unless the 
    discharge is authorized by an NPDES permit. Congress added CWA section 
    402(p) in 1987 to require implementation of a comprehensive program for 
    addressing storm water discharges. Section 402(p)(1) required EPA or 
    NPDES-authorized States or Tribes to issue NPDES permits for the 
    following five classes of storm water discharges composed entirely of 
    storm water (``storm water discharges'') specifically listed under 
    section 402(p)(2):
        (A) a discharge subject to an NPDES permit before February 4, 1987
        (B) a discharge associated with industrial activity
        (C) a discharge from a municipal separate storm sewer system 
    serving a population of 250,000 or more
        (D) a discharge from a municipal separate storm sewer system 
    serving a population of 100,000 or more but less than 250,000
        (E) a discharge that an NPDES permitting authority determines to be 
    contributing to a violation of a water quality standard or a 
    significant contributor of pollutants to the waters of the United 
    States.
        Section 402(p)(3)(A) requires storm water discharges associated 
    with industrial activity to meet all applicable provisions of section 
    402 and section 301 of the CWA, including technology-based requirements 
    and any more stringent requirements necessary to meet water quality 
    standards. Section 402(p)(3)(B) establishes NPDES permit standards for 
    discharges from municipal separate storm sewer systems, or MS4s. NPDES 
    permits for discharges from MS4s (1) may be issued on a system or 
    jurisdiction-wide basis, (2) must include a requirement to effectively 
    prohibit non-storm water discharges into the storm sewers, and (3) must 
    require controls to reduce pollutant discharges to the maximum extent 
    practicable, including best management practices, and other provisions 
    as the Administrator or the States determine to be appropriate for the 
    control of such pollutants. At this time, EPA determines that water 
    quality-based controls, implemented through the iterative processes 
    described today are appropriate for the control of such pollutants and 
    will result in reasonable further progress towards attainment of water 
    quality standards. See sections II.L and II.H.3 of the preamble.
        In CWA section 402(p)(4), Congress established statutory deadlines 
    for the initial steps in implementing the NPDES program for storm water 
    discharges. This section required development of NPDES permit 
    application regulations, submission of NPDES permit applications, 
    issuance of NPDES permits for sources identified in section 402(p)(2), 
    and compliance with NPDES permit conditions. In addition, this section 
    required industrial facilities and large MS4s to submit NPDES permit 
    applications for storm water discharges by February 4, 1990. Medium 
    MS4s were to submit NPDES permit applications by February 4, 1992. EPA 
    and authorized NPDES States were prohibited from requiring an NPDES 
    permit for any other storm water discharges until October 1, 1994.
        Section 402(p)(5) required EPA to conduct certain studies and 
    submit a report to Congress. This requirement is discussed in the 
    following section.
        Section 402(p)(6) requires EPA, in consultation with States and 
    local officials, to issue regulations for the designation of additional 
    storm water discharges to be regulated to protect water quality. It 
    also requires EPA to extend the existing storm water program to 
    regulate newly designated sources. At a minimum, the extension must 
    establish (1) priorities, (2) requirements for State storm water 
    management programs, and (3) expeditious deadlines. Section 402(p)(6) 
    specifies that the program may include performance standards, 
    guidelines, guidance, and management practices and treatment 
    requirements, as
    
    [[Page 68732]]
    
    appropriate. Today's rule implements this section.
    
    D. EPA's Reports to Congress
    
        Under CWA section 402(p)(5), EPA, in consultation with the States, 
    was required to conduct a study. The study was to identify unregulated 
    sources of storm water discharges, determine the nature and extent of 
    pollutants in such discharges, and establish procedures and methods to 
    mitigate the impacts of such discharges on water quality. Section 
    402(p)(5) also required EPA to report the results of the first two 
    components of that study to Congress by October 1, 1988, and the final 
    report by October 1, 1989.
        In March 1995, EPA submitted to Congress a report that reviewed and 
    analyzed the nature of storm water discharges from municipal and 
    industrialacilities that were not already regulated under the initial 
    NPDES regulations for storm water (U.S. Environmental Protection 
    Agency, Office of Water. 1995. Storm Water Discharges Potentially 
    Addressed by Phase II of the National Pollutant Discharge Elimination 
    System Storm Water Program: Report to Congress. Washington, D.C. EPA 
    833-K-94-002) (``Report''). The Report also analyzed associated 
    pollutant loadings and water quality impacts from these unregulated 
    sources. Based on identification of unregulated municipal sources and 
    analysis of information on impacts of storm water discharges from 
    municipal sources, the Report recommended that the NPDES program for 
    storm water focus on the 405 ``urbanized areas'' identified by the 
    Bureau of the Census. The Report further found that a number of 
    discharges from unregulated industrial facilities warranted further 
    investigation to determine the need for regulation. It classified these 
    unregulated industrial discharges in two groups: Group A and Group B. 
    Group A comprised sources that may be considered a high priority for 
    inclusion in the NPDES program for storm water because discharges from 
    these sources are similar or identical to already regulated sources. 
    These ``look alike'' storm water discharge sources were not covered in 
    the initial NPDES regulations for storm water due to the language used 
    to define ``associated with industrial activity.'' In the initial 
    regulations for storm water, ``industrial activity'' is identified 
    using Standard Industrial Classification (SIC) codes. The use of SIC 
    codes led to incomplete categorization of industrial activities with 
    discharges that needed to be regulated to protect water quality. Group 
    B consisted of 18 industrial sectors, which included sources that EPA 
    expected to contribute to storm water contamination due to the 
    activities conducted and pollutants anticipated onsite (e.g., vehicle 
    maintenance, machinery and electrical repair, and intensive 
    agricultural activities).
        EPA reported on the latter component of the section 402(p)(5) study 
    via President Clinton's Clean Water Initiative, which was released on 
    February 1, 1994 (U.S. Environmental Protection Agency, Office of 
    Water. 1994. President Clinton's Clean Water Initiative. Washington, 
    D.C. EPA 800-R-94-001) (``Initiative''). The Initiative addressed a 
    number of issues associated with NPDES requirements for storm water 
    discharges and proposed (1) establishing a phased compliance with a 
    water quality standards approach for discharges from municipal separate 
    storm sewer systems with priority on controlling discharges from 
    municipal growth and development areas, (2) clarifying that the maximum 
    extent practicable standard should be applied in a site-specific, 
    flexible manner, taking into account cost considerations as well as 
    water quality effects, (3) providing an exemption from the NPDES 
    program for storm water discharges from industrial facilities with no 
    activities or significant materials exposed to storm water, (4) 
    providing extensions to the statutory deadlines to complete 
    implementation of the NPDES program for the storm water program, (5) 
    targeting urbanized areas for the requirements in the NPDES program for 
    storm water, and (6) providing control of discharges from inactive and 
    abandoned mines located on Federal lands in a more targeted, flexible 
    manner. Additionally, prior to promulgation of today's rule, section 
    431 of the Agency's Appropriation Act for FY 2000 (Departments of 
    Veterans Affairs and Housing and Urban Development and Independent 
    Agencies Appropriations Act of 2000, Public Law 106-74, section 432 
    (1999)) directed EPA to report on certain matters to be covered in 
    today's rule. That report supplements the study required by CWA Section 
    402(p)(5). EPA is publishing the availability of that report elsewhere 
    in this issue of the Federal Register.
        Several commenters asserted that the Report to Congress is an 
    inadequate basis for the designation and regulation of sources covered 
    under today's final rule, specifically the nationwide designation of 
    small municipal separate storm sewer systems within urbanized areas and 
    construction activities disturbing between one and five acres.
        EPA believes that it has developed an adequate record for today's 
    regulation both through the Report to Congress and the Clean Water 
    Initiative and through more recent activities, including the FACA 
    Subcommittee process, regulatory notices and evaluation of comments, 
    and recent research and analysis. EPA does not interpret the 
    congressional reporting requirements of CWA section 402(p)(5) to be the 
    sole basis for determining sources to be regulated under today's final 
    rule.
        EPA's decision to designate on a national basis small MS4s in 
    urbanized areas is supported by studies that clearly show a direct 
    correlation between urbanization and adverse water quality impacts from 
    storm water discharges. (Schueler, T. 1987. Controlling Urban Runoff: A 
    Practical Manual for Planning & Designing Urban BMPs. Metropolitan 
    Washington Council of Governments). ``Urbanized areas''--within which 
    all small MS4s would be covered--represent the most intensely developed 
    and dense areas of the Nation. They constitute only two percent of the 
    land area but 63 percent of the total population. See section I.B.1, 
    Urban Development, above, for studies and assessments of the link 
    between urban development and storm water impacts on water resources.
        Commenters argued that the Report to Congress does not address 
    storm water discharges from construction sites. They further argued 
    that the designation of small construction sites per today's final rule 
    goes beyond the President's 1994 Initiative because the Initiative only 
    recommends requiring municipalities to implement a storm water 
    management program to control unregulated storm water sources, 
    ``including discharges from construction of less than 5 acres, which 
    are part of growth, development and significant redevelopment 
    activities.'' They point out that the Initiative provides that 
    unregulated storm water discharges not addressed through a municipal 
    program would not be covered by the NPDES program. Commenters assert 
    that EPA has not developed a record independent of its section 
    402(p)(5) studies that demonstrates the necessity of regulating under a 
    separate NPDES permit storm water discharges from smaller construction 
    sites ``to protect water quality.'' EPA disagrees.
        EPA evaluated the nature and extent of pollutants from construction 
    site sources in a process that was separate and distinct from the 
    development of the Report to Congress. Today's decision to regulate 
    certain storm water discharges from construction sites disturbing less 
    than 5 acres arose in part
    
    [[Page 68733]]
    
    out of the 9th Circuit remand in NRDC v. EPA, 966 F.2d 1292 (9th Cir. 
    1992). In that case, the court remanded portions of the Phase I storm 
    water regulations related to discharges from construction sites. Those 
    regulations define ``storm water discharges associated with industrial 
    activity'' to include only those storm water discharges from 
    construction sites disturbing 5 acres or more of total land area (see 
    40 CFR 122.26(b)(14)(x)). In its decision, the court concluded that the 
    5-acre threshold was improper because the Agency had failed to identify 
    information ``to support its perception that construction activities on 
    less than 5 acres are non-industrial in nature'' (966 F.2d at 1306). 
    The court remanded the below 5 acre exemption to EPA for further 
    proceedings (966 F.2d at 1310).
        In a Federal Register notice issued on December 18, 1992, EPA noted 
    that it did not believe that the Court's decision had the effect of 
    automatically subjecting small construction sites to the existing 
    application requirements and deadlines. EPA believed that additional 
    notice and comment were necessary to clarify the status of these sites. 
    The information received during the notice and comment process and 
    additional research, as discussed in section I.B.3 Construction Site 
    Runoff, formed the basis for the designation of construction activity 
    disturbing between one and five acres on a nationwide basis. EPA's 
    objectives in today's proposal include an effort to (1) address the 9th 
    Circuit remand, (2) address water quality concerns associated with 
    construction activities that disturb less than 5 acres of land, and (3) 
    balance conflicting recommendations and concerns of stakeholders.
        One commenter noted that EPA's proposal would fail to regulate 
    industrial facilities identified as Group A and Group B in the March 
    1995 Report to Congress. EPA is relying on the analysis in the Report, 
    which provided that the recommendation for coverage was meant as 
    guidance and was not intended to be an identification of specific 
    categories that must be regulated under Section 402(p)(6). Report to 
    Congress, p. 4-1. The Report recognized the existence of limited data 
    on which to base loadings estimates to support the nationwide 
    designation of individual or categories of sources. Report to Congress, 
    p. 4-44. Furthermore, during FACA Subcommittee discussion, EPA 
    continued to urge stakeholders to provide further data relating to 
    industrial and commercial storm water sources, which EPA did not 
    receive. EPA concluded that, due to insufficient data, these sources 
    were not appropriate for nationwide designation at this time.
    
    E. Industrial Facilities Owned or Operated by Small Municipalities
    
        Congress granted extensions to the NPDES permit application process 
    for selected classes of storm water discharges associated with 
    industrial activity. On December 18, 1991, Congress enacted the 
    Intermodal Surface Transportation Efficiency Act (ISTEA), which 
    postponed NPDES permit application deadlines for most storm water 
    discharges associated with industrial activity at facilities that are 
    owned or operated by small municipalities. EPA and States authorized to 
    administer the NPDES program could not require any municipality with a 
    population of less than 100,000 to apply for or obtain an NPDES permit 
    for any storm water discharge associated with industrial activity prior 
    to October 1, 1992, except for storm water discharges from airports, 
    power plants, or uncontrolled sanitary landfills. See 40 CFR 
    122.26(e)(1); 57 FR 11524, April 2, 1992 (reservation of NPDES 
    application deadlines for ISTEA facilities).
        The facilities exempted by ISTEA discharge storm water in the same 
    manner (and are expected to use identical processes and materials) as 
    the industrial facilities regulated under the 1990 Phase I regulations. 
    Accordingly, these facilities pose similar water quality problems. The 
    extended moratorium for these facilities was necessary to allow 
    municipalities additional time to comply with NPDES requirements. The 
    proposal for today's rule would have maintained the existing deadline 
    for seeking coverage under an NPDES permit (August 7, 2001).
        Today's rule changes the permit application deadline for such 
    municipally owned or operated facilities discharging industrial storm 
    water to make it consistent with the application date for small 
    regulated MS4s. Because EPA missed its March 1999 deadline for 
    promulgating today's rule, and the deadline for MS4s to submit permit 
    applications has been extended to three years and 90 days from the date 
    of this notice, the deadline for permitting ISTEA sources has been 
    similarly extended. The permitting of these sources is discussed below 
    in section ``II.I.3. ISTEA Sources.''
    
    F. Related Nonpoint Source Programs
    
        Today's rule addresses point source discharges of storm water 
    runoff and non-storm water discharges into MS4s. Many of these sources 
    have been addressed by nonpoint source control programs, which are 
    described briefly below.
        In 1987, section 319 was added to the CWA to provide a framework 
    for funding State and local efforts to address pollutants from nonpoint 
    sources not addressed by the NPDES program. To obtain funding, States 
    are required to submit Nonpoint Source Assessment Reports identifying 
    State waters that, without additional control of nonpoint sources of 
    pollution, could not reasonably be expected to attain or maintain 
    applicable water quality standards or other goals and requirements of 
    the CWA. States are also required to prepare and submit for EPA 
    approval a statewide Nonpoint Source Management Program for controlling 
    nonpoint source water pollution to navigable waters within the State 
    and improving the quality of such waters. State program submittals must 
    identify specific best management practices (BMPs) and measures that 
    the State proposes to implement in the first four years after program 
    submission to reduce pollutant loadings from identified nonpoint 
    sources to levels required to achieve the stated water quality 
    objectives.
        State nonpoint source programs funded under section 319 can include 
    both regulatory and nonregulatory State and local approaches. Section 
    319(b)(2)(B) specifies that a combination of ``nonregulatory or 
    regulatory programs for enforcement, technical assistance, financial 
    assistance, education, training, technology transfer, and demonstration 
    projects' may be used, as necessary, to achieve implementation of the 
    BMPs or measures identified in the section 319 submittals.
        Section 6217 of the Coastal Zone Act Reauthorization Amendments 
    (CZARA) of 1990 provides that States with approved coastal zone 
    management programs must develop coastal nonpoint pollution control 
    programs and submit them to EPA and the National Oceanic and 
    Atmospheric Administration (NOAA) for approval. Failure to submit an 
    approvable program will result in a reduction of Federal grants under 
    both the Coastal Zone Management Act and section 319 of the CWA.
        State coastal nonpoint pollution control programs under CZARA must 
    include enforceable policies and mechanisms that ensure implementation 
    of the management measures throughout the coastal management area. EPA 
    issued Guidance Specifying Management Measures for Sources of Nonpoint 
    Pollution in Coastal Waters under section 6217(g) in
    
    [[Page 68734]]
    
    January 1993. The guidance identifies management measures for five 
    major categories of nonpoint source pollution. The management measures 
    reflect the greatest degree of pollutant reduction that is economically 
    achievable for each of the listed sources. These management measures 
    provide reference standards for the States to use in developing or 
    refining their coastal nonpoint programs. A few management measures, 
    however, contain quantitative standards that specify pollutant loading 
    reductions. For example, the New Development Management Measure, which 
    is applicable to construction in urban areas, requires (1) that by 
    design or performance the average annual total suspended solid loadings 
    be reduced by 80 percent and (2) to the extent practicable, that the 
    pre-development peak runoff rate and average volume be maintained.
        EPA and NOAA published Coastal Nonpoint Pollution Control Program: 
    Program Development and Approval Guidance (1993). The document 
    clarifies that States generally must implement management measures for 
    each source category identified in the EPA guidance developed under 
    section 6217(g). Coastal Nonpoint Pollution Control Programs are not 
    required to address sources that are clearly regulated under the NPDES 
    program as point source discharges. Specifically, such programs would 
    not need to address small MS4s and construction sites covered under 
    NPDES storm water permits (both general and individual).
    
    II. Description of Program
    
    A. Overview
    
    1. Objectives EPA Seeks To Achieve in Today's Rule
        EPA seeks to achieve several objectives in today's final rule. 
    First, EPA is implementing the requirement under CWA section 402(p)(6) 
    to provide a comprehensive storm water program that designates and 
    controls additional sources of storm water discharges to protect water 
    quality. Second, EPA is addressing storm water discharges from the 
    activities exempted under the 1990 storm water permit application 
    regulations that were remanded by the Ninth Circuit Court of Appeals in 
    NRDC v. EPA, 966 F.2d 1292 (9th Circuit, 1992). These are construction 
    activities disturbing less than 5 acres and so-called ``light'' 
    industrial activities not exposed to storm water (see discussion of 
    ``no exposure'' below). Third, EPA is providing coverage for the so-
    called ``donut holes'' created by the existing NPDES storm water 
    program. Donut holes are geographic gaps in the NPDES storm water 
    program's regulatory scheme. They are MS4s located within areas covered 
    by the existing NPDES storm water program, but not currently addressed 
    by the storm water program because it is based on political 
    jurisdictions. Finally, EPA also is trying to promote watershed 
    planning as a framework for implementing water quality programs where 
    possible.
        Although EPA had options for different approaches (see alternatives 
    discussed in the January 9, 1998, proposed regulation), EPA believes it 
    can best achieve its objectives through flexible innovations within the 
    framework of the NPDES program. Unlike the interim section 402(p)(6) 
    storm water regulations EPA promulgated in 1995, EPA no longer 
    designates all of the unregulated storm water discharges for nationwide 
    coverage under the NPDES program for storm water. The framework for 
    today's final rule is one that balances automatic designation on a 
    nationwide basis and locally-based designation and waivers. Nationwide 
    designation applies to those classes or categories of storm water 
    discharges that EPA believes present a high likelihood of having 
    adverse water quality impacts, regardless of location. Specifically, 
    today's rule designates discharges from small MS4s located in urbanized 
    areas and storm water discharges from construction activities that 
    result in land disturbance equal to or greater than one and less than 
    five acres. As noted under Section I.B., Water Quality Concerns/
    Environmental Impact Studies and Assessments, these two categories of 
    storm water sources, when unregulated, tend to cause significant 
    adverse water quality impacts. Additional sources are not covered on a 
    nationwide basis either because EPA currently lacks information 
    indicating a consistent potential for adverse water quality impact or 
    because EPA believes that the likelihood of adverse impacts on water 
    quality is low, with some localized exceptions. Additional individual 
    sources or categories of storm water discharges could, however, be 
    covered under the program through a local designation process. A 
    permitting authority may designate additional small MS4s after 
    developing designation criteria and applying those criteria to small 
    MS4s located outside of an urbanized area, in particular those with a 
    population of 10,000 or more and a population density of at least 
    1,000. Exhibit 1 illustrates the designation framework for today's 
    final rule.

    [[Page 68736]]
    
        The designation framework for today's final rule provides a 
    significant degree of flexibility. The proposed provisions for 
    nationwide designation of storm water discharges from construction and 
    from small MS4s in urbanized areas allowed for a waiver of applicable 
    requirements based on appropriate water quality conditions. Today's 
    final rule expands and simplifies those waivers.
        The permitting authority may waive the requirement for a permit for 
    any small MS4 serving a jurisdiction with a population of less than 
    1,000 unless storm water controls are needed because the MS4 is 
    contributing to a water quality impairment. The permitting authority 
    may also waive permit coverage for MS4s serving a jurisdiction with a 
    population of less than 10,000 if all waters that receive a discharge 
    from the MS4 have been evaluated and discharges from the MS4 do not 
    significantly contribute to a water quality impairment or have the 
    potential to cause an impairment. Today's rule also allows States with 
    a watershed permitting approach to phase in coverage for MS4s in 
    jurisdictions with populations under 10,000.
        Water quality conditions are also the basis for a waiver of 
    requirements for storm water discharges from construction activities 
    disturbing between one and five acres. For these small construction 
    sources, the rule provides significant flexibility for waiving 
    otherwise applicable regulatory requirements where a permitting 
    authority determines, based on water quality and watershed 
    considerations, that storm water discharge controls are not needed.
        Coverage can be extended to municipal and construction sources 
    outside the nationwide designated classes or categories based on 
    watershed and case-by-case assessments. For the municipal storm water 
    program, today's rule provides broad discretion to NPDES permitting 
    authorities to develop and implement criteria for designating storm 
    water discharges from small MS4s outside of urbanized areas. Other 
    storm water discharges from unregulated industrial, commercial, and 
    residential sources will not be subject to the NPDES permit 
    requirements unless a permitting authority determines on a case-by-case 
    basis (or on a categorical basis within identified geographic areas 
    such as a State or watershed) that regulatory controls are needed to 
    protect water quality. EPA believes that the flexibility provided in 
    today's rule facilitates watershed planning.
    2. General Requirements for Regulated Entities Under Today's Rule
        As previously noted, today's final rule defines additional classes 
    and categories of storm water discharges for coverage under the NPDES 
    program. These designated dischargers are required to seek coverage 
    under an NPDES permit. Furthermore, all NPDES-authorized States and 
    Tribes are required to implement these provisions and make any 
    necessary amendments to current State and Tribal NPDES regulations to 
    ensure consistency with today's final rule. EPA remains the NPDES 
    permitting authority for jurisdictions without NPDES authorization.
        Today's final rule includes some new requirements for NPDES 
    permitting authorities implementing the CWA section 402(p)(6) program. 
    EPA has made a significant effort to build flexibility into the program 
    while attempting to maintain an appropriate level of national 
    consistency. Permitting authorities must ensure that NPDES permits 
    issued to MS4s include the minimum control measures established under 
    the program. Permitting authorities also have the ability to make 
    numerous decisions including who is regulated under the program, i.e., 
    case-by-case designations and waivers, and how responsibilities should 
    be allocated between regulated entities.
        Today's final rule extends the NPDES program to include discharges 
    from the following: small MS4s within urbanized areas (with the 
    exception of systems waived from the requirements by the NPDES 
    permitting authority); other small MS4s meeting designation criteria to 
    be established by the permitting authority; and any remaining MS4 that 
    contributes substantially to the storm water pollutant loadings of a 
    physically interconnected MS4 already subject to regulation under the 
    NPDES program. Small MS4s include urban storm sewer systems owned by 
    Tribes, States, political subdivisions of States, as well as the United 
    States, and other systems located within an urbanized area that fall 
    within the definition of an MS4. These include, for example, State 
    departments of transportation (DOTs), public universities, and federal 
    military bases.
        Today's final rule requires all regulated small MS4s to develop and 
    implement a storm water management program. Program components include, 
    at a minimum, 6 minimum measures to address: public education and 
    outreach; public involvement; illicit discharge detection and 
    elimination; construction site runoff control; post-construction storm 
    water management in new development and redevelopment; and pollution 
    prevention and good housekeeping of municipal operations. These program 
    components will be implemented through NPDES permits. A regulated small 
    MS4 is required to submit to the NPDES permitting authority, either in 
    its notice of intent (NOI) or individual permit application, the BMPs 
    to be implemented and the measurable goals for each of the minimum 
    control measures listed above.
        The rule addresses all storm water discharges from construction 
    site activities involving clearing, grading and excavating land equal 
    to or greater than 1 acre and less than 5 acres, unless requirements 
    are otherwise waived by the NPDES permitting authority. Discharges from 
    such sites, as well as construction sites disturbing less than 1 acre 
    of land that are designated by the permitting authority, are required 
    to implement requirements set forth in the NPDES permit, which may 
    reference the requirements of a qualifying local program issued to 
    cover such discharges.
        The rule also addresses certain other sources regulated under the 
    existing NPDES program for storm water. For municipally-owned 
    industrial sources required to be regulated under the existing NPDES 
    storm water program but exempted from immediate compliance by the 
    Intermodal Surface Transportation Act of 1991 (ISTEA), the rule revises 
    the existing deadline for seeking coverage under an NPDES permit 
    (August 7, 2001) to make it consistent with the application date for 
    small regulated MS4s. (See section I.3. below.) The rule also provides 
    relief from NPDES storm water permitting requirements for industrial 
    sources with no exposure of industrial materials and activities to 
    storm water.
    3. Integration of Today's Rule With the Existing Storm Water Program
        In developing an approach for today's final rule, numerous early 
    interested stakeholders encouraged EPA to seek opportunities to 
    integrate, where possible, the proposed Phase II requirements with 
    existing Phase I requirements, thus facilitating a unified storm water 
    discharge control program. EPA believes that this objective is met by 
    using the NPDES framework. This framework is already applied to 
    regulated storm water discharge sources and is extended to those 
    sources designated under today's rule. This approach facilitates 
    program consistency, public access to information, and program 
    oversight.
    
    [[Page 68737]]
    
        EPA believes that today's final rule provides consistency in terms 
    of program coverage and requirements for existing and newly designated 
    sources. For example, the rule includes most of the municipal donut 
    holes, those MS4s located in incorporated places, townships or towns 
    with a population under 100,000 that are within Phase I counties. These 
    MS4s are not addressed by the existing NPDES storm water program while 
    MS4s in the surrounding county are currently addressed. In addition, 
    the minimum control measures required in today's rule for regulated 
    small MS4s are very similar to a number of the permit requirements for 
    medium and large MS4s under the existing storm water program. Following 
    today's rule, permit requirements for all regulated MS4s (both those 
    under the existing program and those under today's rule) will require 
    implementation of BMPs. Furthermore, with regard to the development of 
    NPDES permits to protect water quality, EPA intends to apply the August 
    1, 1996, Interim Permitting Approach for Water Quality-Based Effluent 
    Limitations in Storm Water Permits (hereinafter, ``Interim Permitting 
    Approach'') (see Section II.L.1. for further description) to all MS4s 
    covered by the NPDES program.
        EPA is applying NPDES permit requirements to construction sites 
    below 5 acres that are similar to the existing requirements for those 
    above 5 acres and above. In addition, today's rule allows compliance 
    with qualifying local, Tribal, or State erosion and sediment controls 
    to meet the erosion and sediment control requirements of the general 
    permits for storm water discharges associated with construction, both 
    above and below 5 acres.
    4. General Permits
        EPA recommends using general permits for all newly regulated storm 
    water sources under today's rule. The use of general permits, instead 
    of individual permits, reduces the administrative burden on permitting 
    authorities, while also limiting the paperwork burden on regulated 
    parties seeking permit authorization. Permitting authorities may, of 
    course, require individual permits in some cases to address specific 
    concerns, including permit non-compliance.
        EPA recommends that general permits for MS4s, in particular, be 
    issued on a watershed basis, but recognizes that each permitting 
    authority must decide how to develop its general permit(s). Permit 
    conditions developed to address concerns and conditions of a specific 
    watershed could reflect a watershed plan; such permit conditions must 
    provide for attainment of applicable water quality standards (including 
    designated uses), allocations of pollutant loads established by a TMDL, 
    and timing requirements for implementation of a TMDL. If the permitting 
    authority issues a State-wide general permit, the permitting authority 
    may include separate conditions tailored to individual watersheds or 
    urbanized areas. Of course, for a newly regulated MS4, modification of 
    an existing individual MS4 permit to include the newly regulated MS4 as 
    a ``limited co-permittee'' also remains an option.
    5. Tool Box
        During the FACA process, many Storm Water Phase II FACA 
    Subcommittee representatives expressed an interest, which was endorsed 
    by the full Committee, in having EPA develop a ``tool box'' to assist 
    States, Tribes, municipalities, and other parties involved in the Phase 
    II program. EPA made a commitment to work with Storm Water Phase II 
    FACA Subcommittee representatives in developing such a tool box, with 
    the expectation that a tool box would facilitate implementation of the 
    storm water program in an effective and cost-efficient manner. EPA has 
    developed a preliminary working tool box (available on EPA's web page 
    at www.epa.gov/owm/sw/toolbox). EPA intends to have the tool box fully 
    developed by the time of the first general permits. EPA also intends to 
    update the tool box as resources and data become available. The tool 
    box will include the following eight main components: fact sheets; 
    guidances; a menu of BMPs for the six MS4 minimum measures; an 
    information clearinghouse; training and outreach efforts; technical 
    research; support for demonstration projects; and compliance 
    monitoring/assistance tools. EPA intends to issue the menu of BMPs, 
    both structural and non-structural, by October 2000. In addition, EPA 
    will issue by October 2000 a ``model'' permit and will issue by October 
    2001 guidance materials on the development of measurable goals for 
    municipal programs.
        In an attempt to avoid duplication, the Agency has undertaken an 
    effort to identify and coordinate sources of information that relate to 
    the storm water discharge control program from both inside and outside 
    the Agency. Such information includes research and demonstration 
    projects, grants, storm water management-related programs, and 
    compendiums of available documents, including guidances, related 
    directly or indirectly to the comprehensive NPDES storm water program. 
    Based on this effort, EPA is developing a tool box containing fact 
    sheets and guidance documents pertaining to the overall program and 
    rule requirements (e.g., guidance on municipal and construction 
    programs, and permitting authority guidance on designation and waiver 
    criteria); models of current programs aimed at assisting States, 
    Tribes, municipalities, and others in establishing programs; a 
    comprehensive list of reference documents organized according to 
    subject area (e.g., illicit discharges, watersheds, water quality 
    standards attainment, funding sources, and similar types of 
    references); educational materials; technical research data; and 
    demonstration project results. The information collected by EPA will 
    not only provide the background for tool box materials, but will also 
    be made available through an information clearinghouse on the world 
    wide web.
        With assistance from EPA, the American Public Works Association 
    (APWA) developed a workbook and series of workshops on the proposed 
    Phase II rule. Ten workshops were held from September 1998 through May 
    1999. Depending on available funding, these workshops may continue 
    after publication of today's final rule. EPA also intends to provide 
    training to enable regional offices to educate States, Tribes, and 
    municipalities about the storm water program and the availability of 
    the tool box materials.
        The CWA currently provides funding mechanisms to support activities 
    related to storm water. These mechanisms will be described in the tool 
    box. Activities funded under grant and loan programs, which could be 
    used to assist in storm water program development, include programs in 
    the nonpoint source area, storm water demonstration projects, source 
    water protection and wastewater construction projects. EPA has already 
    provided funding for numerous research efforts in these areas, 
    including a database of BMP effectiveness studies (described below), an 
    assessment of technologies for storm water management, a study of the 
    effectiveness of storm water BMPs for controlling the impacts of 
    watershed imperviousness, protocols for wet weather monitoring, 
    development of a dynamic model for wet weather flows, and numerous 
    outreach projects.
        EPA has entered into a cooperative agreement with the Urban Water 
    Resources Research Council of the American Society of Civil Engineers 
    (ASCE) to develop a scientifically-based management tool for the 
    information
    
    [[Page 68738]]
    
    needed to evaluate the effectiveness of urban storm water runoff BMPs 
    nationwide. The long-term goal of the National Stormwater BMP Database 
    project is to promote technical design improvements for BMPs and to 
    better match their selection and design to the local storm water 
    problems being addressed. The project team has collected and evaluated 
    hundreds of existing published BMP performance studies and created a 
    database covering about 75 test sites. The database includes detailed 
    information on the design of each BMP and its watershed 
    characteristics, as well as its performance. Eventually the database 
    will include the nationwide collection of information on the 
    characteristics of structural and non-structural BMPs, data collection 
    efforts (e.g., sampling and flow gaging equipment), climatological 
    characteristics, watershed characteristics, hydrologic data, and 
    constituent data. The database will continue to grow as new BMP data 
    become available. The initial release of the database, which includes 
    data entry and retrieval software, is available on CD-ROM and operates 
    on Windows-compatible personal computers. The ASCE project 
    team envisions that periodic updates to the database will be 
    distributed through the Internet. The team is currently developing a 
    system for Internet retrieval of selected database records, and this 
    system is expected to be available in early 2000.
        EPA and ASCE invite BMP designers, owners and operators to 
    participate in the continuing database development effort. To make this 
    effort successful, a large database is essential. Interested persons 
    are encouraged to submit their BMP performance evaluation data and 
    associated BMP watershed characteristics for potential entry into the 
    database. The software included in the CD-ROM allows data providers to 
    enter their BMP data locally, retain and edit the data as needed, and 
    submit them to the ASCE Database Clearinghouse when ready.
        To obtain a copy of the database, please contact Jane Clary, 
    Database Clearinghouse Manager, Wright Water Engineers, Inc., 2490 W. 
    26th Ave., Suite 100A, Denver, CO 80211; Phone 303-480-1700; E-mail

        In addition, EPA requests that researchers planning to conduct BMP 
    performance evaluations compile and collect BMP reporting information 
    according to the standard format developed by ASCE. The format is 
    provided with the database software and is also available on the ASCE 
    website at www.asce.org/peta/tech/nsbd01.html.
    6. Deadlines Established in Today's Action
        Exhibit 2 outlines the various deadlines established under today's 
    final rule. EPA believes that the dates allow sufficient time for 
    completion of both the NPDES permitting authority's and the permittee's 
    program responsibilities.

    B. Readable Regulations
    
        Today, EPA is finalizing new regulations in a ``readable 
    regulation'' format. This reader-friendly, plain language approach is a 
    departure from traditional regulatory language and should enhance the 
    rule's readability. These plain language regulations use questions and 
    answers, ``you'' to identify the person who must comply, and terms like 
    ``must'' rather than ``shall'' to identify a mandate. This new format, 
    which minimizes layers of subparagraphs, should also allow the reader 
    to easily locate specific provisions of the regulation.
        Some sections of today's final rule are presented in the 
    traditional language and format because these sections amend existing 
    regulations. The readable regulation format was not used in these 
    existing provisions in an attempt to avoid confusion or disruption
    
    [[Page 68739]]
    
    of the readability of the existing regulations.
        Most commenters supported EPA's use of plain language and agreed 
    with EPA that the question and answer format makes the rule easier to 
    understand. Three commenters thought that EPA should retain the 
    traditional rule format. The June 1, 1998, Presidential memorandum 
    directs all government agencies to write documents in plain language. 
    Based on the majority of the comments, EPA has retained the plain 
    language format used in the January 9, 1998, proposal in today's final 
    rule.
        The proposal to today's final rule included guidance as well as 
    legal requirements. The word ``must'' indicates a requirement. Words 
    like ``should,'' ``could,'' or ``encourage'' indicate a recommendation 
    or guidance. In addition, the guidance was set off in parentheses to 
    distinguish it from requirements.
        EPA received numerous comments supporting the inclusion of guidance 
    in the text of the Code of Federal Regulations (CFR), as well as 
    comments opposing inclusion of guidance. Supporters stated that 
    preambles and guidance documents are often not accessible when rules 
    are implemented. Any language not included in the CFR is therefore not 
    available when it may be most needed. Commenters that opposed including 
    guidance in the CFR expressed the concern that any language in the rule 
    might be interpreted as a requirement, in spite of any clarifying 
    language. They suggested that guidance be presented in the preamble and 
    additional guidance documents.
        The majority of commenters on this issue thought that the guidance 
    should be retained but the distinction between requirements and 
    guidance should be better clarified. Suggestions included clarifying 
    text, symbols, and a change from use of the word ``should'' to ``EPA 
    recommends'' or ``EPA suggests''. EPA believes that it is important to 
    include the guidance in the rule and agrees that the distinction 
    between requirements and EPA recommendations must be very clear. In 
    today's final rule, EPA has put the guidance in paragraphs entitled 
    ``Guidance'' and replaced the word ``should'' with ``EPA recommends.'' 
    This is intended to clarify that the recommendations contained in the 
    guidance paragraphs are not legally binding.
    
    C. Program Framework: NPDES Approach
    
        Today's rule regulates Phase II sources using the NPDES permit 
    program. EPA interprets Clean Water Act section 402(p)(6) as 
    authorizing the Agency to develop a storm water program for Phase II 
    sources either as part of the existing NPDES permit program or as a 
    stand alone non-NPDES program such as a self-implementing rule. Under 
    either approach, EPA interprets section 402(p)(6) as directing EPA to 
    publish regulations that ``regulate'' the remaining unregulated 
    sources, specifically to establish requirements that are federally 
    enforceable under the CWA. Although EPA believes that it has the 
    discretion to not require sources regulated under CWA section 402(p)(6) 
    to be covered by NPDES permits, the Agency has determined, for the 
    reasons discussed below, that it is most appropriate to use NPDES 
    permits in implementing the program to address the sources designated 
    for regulation in today's rule.
        As discussed in Section II.A, Overview, EPA sought to achieve 
    certain goals in today's final rule. EPA believes that the NPDES 
    program best achieves EPA's goals for today's final rule for the 
    reasons discussed below.
        Requiring Phase II sources to be covered by NPDES permits helps 
    address the consistency problems currently caused by municipal ``donut 
    holes.'' Donut holes are gaps in program coverage where a small 
    unregulated MS4 is located next to or within a regulated larger MS4 
    that is subject to an NPDES permit under the Phase I NPDES storm water 
    program. The existence of such ``donut holes'' creates an equity 
    problem because similar discharges may remain unregulated even though 
    they cause or contribute to the same adverse water quality impacts. 
    Using NPDES permits to regulate the unregulated discharges in these 
    areas is intended to facilitate the development of a seamless 
    regulatory program for the mitigation and control of contaminated storm 
    water discharges in an urbanized area. For example, today's rule allows 
    a newly regulated MS4 to join as a ``limited'' co-permittee with a 
    regulated MS4 by referencing a common storm water management program. 
    Such cooperation should be further encouraged by the fact that the 
    minimum control measures required in today's rule for regulated small 
    MS4s are very similar to a number of the permit requirements for medium 
    and large MS4s under the Phase I storm water program. The minimum 
    control measures applicable to discharges from smaller MS4s are 
    described with slightly more generality than under the Phase I permit 
    application regulations for larger MS4s, thus enabling maximum 
    flexibility for operators of smaller MS4s to optimize efforts to 
    protect water quality.
        Today's rule also applies NPDES permit requirements to construction 
    sites below 5 acres that are similar to the existing requirements for 
    those 5 acres and above. In addition, the rule would allow compliance 
    with qualifying local, Tribal, or State erosion and sediment controls 
    to meet the erosion and sediment control requirements of the general 
    permits for storm water discharges associated with construction, both 
    above and below 5 acres.
        Incorporating the CWA section 402(p)(6) program into the NPDES 
    program capitalizes upon the existing governmental infrastructure for 
    administration of the NPDES program. Moreover, much of the regulated 
    community already understands the NPDES program and the way it works.
        Another goal of the NPDES program approach is to provide 
    flexibility in order to facilitate and promote watershed planning and 
    sensitivity to local conditions. NPDES permits promote those goals in 
    several ways. NPDES general permits may be used to cover a category of 
    regulated sources on a watershed basis or within political boundaries. 
    The NPDES permitting process provides a mechanism for storm water 
    controls tailored on a case-by-case basis, where necessary. In 
    addition, the NPDES permit requirements of a permittee may be satisfied 
    by another cooperating entity. Finally, NPDES permits may incorporate 
    the requirements of existing State, Tribal and local programs, thereby 
    accommodating State and Tribes seeking to coordinate the storm water 
    program with other programs, including those that focus on watershed-
    based nonpoint source regulation.
        In promoting the watershed approach to program administration, EPA 
    believes NPDES general permits can cover a category of dischargers 
    within a defined geographic area. Areas can be defined very broadly to 
    include political boundaries (e.g., county), watershed boundaries, or 
    State or Tribal land.
        NPDES permits generally require an application or a notice of 
    intent(NOI) to trigger coverage. This information exchange assures 
    communication between the permitting authority and the regulated 
    community. This communication is critical in ensuring that the 
    regulated community is aware of the requirements and the permitting 
    authority is aware of the potential for adverse impacts to water 
    quality from identifiable locations. The NPDES permitting process 
    includes the public as a valuable stakeholder and ensures
    
    [[Page 68740]]
    
    that the public is included and information is made publicly available.
        Another concern for EPA and several stakeholders was that the 
    program ensure citizen participation. The NPDES approach ensures 
    opportunities for citizen participation throughout the permit issuance 
    process, as well as in enforcement actions. NPDES permits are also 
    federally enforceable under the CWA.
        EPA believes that the use of NPDES permits makes a significant 
    difference in the degree of compliance with regulations in the storm 
    water program. The NPDES program provides for public participation in 
    the development, enforcement and revision of storm water management 
    programs. Citizen suit enforcement has assisted in focusing attention 
    on adverse water quality impacts on a localized, public priority basis. 
    Citizens frequently rely on the NPDES permitting process and the 
    availability of NOIs to track program implementation and help them 
    enforce regulatory requirements.
        NPDES permits are also advantageous to the permittee. The NPDES 
    permit informs the permittee about the scope of what it is expected do 
    to be in compliance with the Clean Water Act. As explained more fully 
    in EPA's April 1995 guidance, Policy Statement on Scope of Discharge 
    Authorization and Shield Associated with NPDES Permits, compliance with 
    an NPDES permit constitutes compliance with the Clean Water Act (see 
    CWA section 402(k)). In addition, NPDES permittees are excluded from 
    duplicative regulatory regimes under the Resource Conservation and 
    Recovery Act and the Comprehensive Emergency Response, Compensation and 
    Liability Act under RCRA's exclusions to the definition of ``solid 
    waste'' and CERCLA's exemption for ``federally permitted releases.''
        EPA considered suggestions that the Agency authorize today's rule 
    to be implemented as a self-implementing rule. This would be a 
    regulation promulgated at the Federal, State, or Tribal level to 
    control some or all of the storm water dischargers regulated under 
    today's rule. Under this approach, a rule would spell out the specific 
    requirements for dischargers and impose the restrictions and conditions 
    that would otherwise be contained in an NPDES permit. It would be 
    effective until modified by EPA, a State, or a Tribe, unlike an NPDES 
    permit which cannot exceed a duration of five years. Some stakeholders 
    believed that this approach would reduce the burden on the regulated 
    community (e.g., by not requiring permit applications), and 
    considerably reduce the amount of additional paperwork, staff time and 
    accounting required to administer the proposed permit requirements.
        EPA is sensitive to the interest of some stakeholders in having a 
    streamlined program that minimizes the burden associated with permit 
    administration and maximizes opportunities for field time spent by 
    regulatory authorities. Key provisions in today's rule address some of 
    these concerns by promoting a streamlined approach to permit issuance 
    by, for example, using general permits and allowing the incorporation 
    of existing programs. By adopting the NPDES approach rather than a 
    self-implementing rule, today's rule also allows for consistent 
    regulation between larger MS4s and construction sites regulated under 
    the existing storm water management rule and smaller sources regulated 
    under today's rule.
        EPA believes that it is most appropriate to use NPDES permits to 
    implement a program to address the sources regulated by today's rule. 
    In addition to the reasons discussed above, NPDES permits provide a 
    better mechanism than would a self-implementing rule for tailoring 
    storm water controls on a case-by-case basis, where necessary. One 
    commenter reasoned this concern could be addressed by including 
    provisions in the regulation that allow site-specific BMPs (i.e., case-
    by-case permits), suggesting storm water discharges that might require 
    site-specific BMPs can be identified during the designation process of 
    the regulatory authority. EPA believes that, in addition to its 
    complexity, the commenter's approach lacks the other advantages of the 
    NPDES permitting process.
        A self-implementing rule would not ensure the degree of public 
    participation that the NPDES permit process provides for the 
    development, enforcement and revision of the storm water management 
    program. A self-implementing rule also might not have provided the 
    regulated community the ``permit shield'' under CWA section 402(k) that 
    is provided by an NPDES permit. Based on all these considerations, EPA 
    declined to adopt a self-implementing rule approach and adopted the 
    NPDES approach.
        Some State representatives sought alternative approaches for State 
    implementation of the storm water program for Phase II sources. These 
    State representatives asserted that a non-NPDES alternative approach 
    best facilitated watershed management and avoided duplication and 
    overlapping regulations. These representatives believed the NPDES 
    approach would undercut State programs that had developed storm water 
    controls tailored to local watershed concerns. Finally, a number of 
    commenters expressed the view that States implement a variety of 
    programs not based on the CWA that are effective in controlling storm 
    water, and that EPA should provide incentives for their implementation 
    and improvement in performance.
        Throughout the development of the rule, State representatives 
    sought alternatives to the NPDES approach for State implementation of 
    the storm water program for Phase II sources. Discussions focused on an 
    approach whereby States could develop an alternative program that EPA 
    would approve or disapprove based on identified criteria, including 
    that the alternative non-NPDES program would result in ``equivalent or 
    better protection of water quality.'' The State representatives, 
    however, were unable to propose or recommend criteria for gauging 
    whether a program would provide equivalent protection. EPA also did not 
    receive any suggestions for objective, workable criteria in response to 
    the Agency's explicit request for specific criteria (by which EPA could 
    objectively judge such programs) in the preamble to the proposed rule.
        EPA evaluated several existing State initiatives to address storm 
    water and found many cases where standards under State programs may be 
    coordinated with the Federal storm water program. Where the NPDES 
    permit is developed in coordination with State standards, there are 
    opportunities to avoid duplication and overlapping requirements. Under 
    today's rule, an NPDES permitting authority may include conditions in 
    the NPDES permit that direct an MS4 to follow the requirements imposed 
    under State standards, rather than the requirements of Sec. 122.34(b). 
    This is allowed as long as the State program at a minimum imposes the 
    relevant requirements of Sec. 122.34(b). Additional opportunities 
    follow from other provisions in today's rule.
        Seeking to further explore the feasibility of a non-NPDES approach, 
    the Agency, after the proposal, had extensive discussions with 
    representatives of a number of States. Discussions related specifically 
    to possible alternatives for regulations of urban storm water 
    discharges and MS4s specifically. The Agency also sought input on these 
    issues from other stakeholders.
        As a result of these discussions, many of the commenters provided 
    input on issues such as: whether or not the Agency should require NPDES 
    permits; whether location of MS4s in urbanized
    
    [[Page 68741]]
    
    areas should be the basis for designation or whether designation should 
    be based on other determinations relating to water quality; whether 
    States should be allowed to satisfy the conditions of the rule through 
    the use of existing State programs; and issues concerning timing and 
    resources for program implementation.
        In response, today's rule still follows the regulatory scheme of 
    the proposed rule, but incorporates additional flexibility to address 
    some of the concerns raised by commenters.
        In order to facilitate implementation by States that utilize a 
    watershed permitting approach or similar approach (i.e., based on a 
    State's unified watershed assessments), today's rule allows States to 
    phase in coverage for MS4s in jurisdictions with a population less than 
    10,000. Under such an approach, States could focus their resources on a 
    rolling basis to assist smaller MS4s in developing storm water 
    programs.
        In addition, in response to concerns that the rule should not 
    require permit coverage for MS4s that do not significantly contribute 
    to water quality impairments, today's rule provides options for two 
    waivers for small MS4s. The rule allows permitting authorities to 
    exempt from the requirement for a permit any MS4 serving a jurisdiction 
    with a population less than 1,000, unless the State determines that the 
    MS4 must implement storm water controls because it is significantly 
    contributing to a water quality impairment. A second waiver option 
    applies to MS4s serving a jurisdiction with a population less than 
    10,000. For those MS4s, the State must determine that discharges from 
    the MS4 do not significantly contribute to a water quality impairment, 
    or have the potential for such an impairment, in order to provide the 
    exemption. The State must review this waiver on a periodic basis no 
    less frequently than once every five years.
        Throughout the development of today's rule, commenters questioned 
    whether the Clean Water Act authorized the use of the NPDES permit 
    program, pointing out that the text of CWA 402(p)(6) does not use the 
    word ``permit.'' Based on the absence of the word ``permit'' and the 
    express mention of State storm water management programs, the 
    commenters asserted that Congress did not intend for Phase II sources 
    to be regulated using NPDES permits.
        EPA disagrees with the commenters' interpretation of section 
    402(p)(6). Section 402(p)(6) does not preclude use of permits as part 
    of the ``comprehensive program'' to regulate designated sources. The 
    language provides EPA with broad discretion in the establishment of the 
    ``comprehensive program.'' Absence of the word ``permit'' (a term that 
    the statute does not otherwise define) does not preclude use of a 
    permit, which is a familiar and reasonably well understood regulatory 
    implementation vehicle. First, section 402(p)(6) says that EPA must 
    establish a comprehensive program that ``shall, at a minimum, establish 
    priorities, establish requirements for State stormwater management 
    programs, and establish expeditious deadlines.'' The ``at a minimum'' 
    language suggests that the Agency may, and perhaps should, develop a 
    comprehensive program that does more than merely attend to these 
    minimum criteria. Use of the term ``at a minimum'' preserves for the 
    Agency broad discretion to establish a comprehensive program that 
    includes use of NPDES permits.
        Further, in the final sentence of the section, Congress included 
    additional language to affirm the Agency's discretion. The final 
    sentence clarifies that the Phase II program ``may include performance 
    standards, guidelines, guidance, and management practices and treatment 
    requirements, as appropriate.'' Under existing CWA programs, 
    performance standards, (effluent limitations) guidelines, management 
    practices, and treatment requirements are typically implemented through 
    NPDES or dredge and fill permits.
        Although EPA believes that it had the discretion to not require 
    permits, the Agency has determined that it is reasonable to interpret 
    section 402(p)(6) to authorize permits. Moreover, for the reasons 
    discussed above, the Agency believes that it is appropriate to use 
    NPDES permits in implementing today's rule.
    
    D. Federal Role
    
        Today's final rule describes EPA's approach to expand the existing 
    storm water program under CWA section 402(p)(6). As in all other 
    Federal programs, the Federal government plays an integral role in 
    complying with, developing, implementing, overseeing, and enforcing the 
    program. This section describes EPA's role in the revised storm water 
    program.
    1. Develop Overall Framework of the Program
        The storm water discharge control program under CWA section 
    402(p)(6) consists of the rule, tool box, and permits. EPA's primary 
    role is to ensure timely development and implementation of all 
    components. Today's rule is a refinement of the first step in 
    developing the program. EPA is fully committed to continuing to work 
    with involved stakeholders on developing the tool box and issuing 
    permits. As noted in today's rule, EPA will assess the municipal storm 
    water program based on (1) evaluations of data from the NPDES municipal 
    storm water program, (2) research concerning water quality impacts on 
    receiving waters from storm water, and (3) research on BMP 
    effectiveness. (Section II.H, Municipal Role, provides a more detailed 
    discussion of this provision.)
        EPA is planning to standardize minimum requirements for 
    construction and post-construction BMPs in a new rulemaking under Title 
    III of the CWA. While larger construction sites are already subject to 
    NPDES permits (and smaller sites will be subject to permits pursuant to 
    today's rule), the permits generally do not contain specific 
    requirements for BMP design or performance. The permits require the 
    preparation of storm water pollution prevention plans, but actual BMP 
    selection and design is at the discretion of permittees, in conformance 
    with applicable State and local requirements. Where there are existing 
    State and local requirements specific to BMPs, they vary widely, and 
    many jurisdictions do not have such requirements.
        In developing these regulations, EPA intends to evaluate the 
    inclusion of design and maintenance criteria as minimum requirements 
    for a variety of BMPs used for erosion and sediment control at 
    construction sites, as well as for permanent BMPs used to manage post-
    construction storm water discharges. The Agency plans to consider the 
    merits and performance of all appropriate management practices (both 
    structural and non-structural) that can be used to reduce adverse water 
    quality impacts. EPA does not intend to require the use of particular 
    BMPs at specific sites, but plans to assist builders and developers in 
    BMP selection by publishing data on the performance to be expected by 
    various BMP types. EPA would like to build upon the successes of some 
    of the effective State and local storm water programs currently in 
    place around the country, and to establish nation-wide criteria to 
    support builders and local jurisdictions in appropriate BMP selection.
    2. Encourage Consideration of Smart Growth Approaches
        In the proposal, EPA invited comment on possible approaches for 
    providing
    
    [[Page 68742]]
    
    incentives for local decision making that would limit the adverse 
    impacts of growth and development on water quality. EPA asked for 
    comments on this ``smart growth'' approach.
        EPA received comments on all sides of this issue. A number of 
    commenters supported the idea of ``smart growth'' incentives but did 
    not present concrete ideas. Several commenters suggested ``smart 
    growth'' criteria. States that have adopted ``smart growth'' laws were 
    worried that EPA's focus on urbanized areas for municipal requirements 
    could encourage development outside of designated growth areas. Today's 
    final rule clearly allows States to expand coverage of their municipal 
    storm water program outside of urbanized areas. In addition, the 
    flexibility of the six municipal minimum measures should avoid 
    encouragement of development into rural rather than urban areas. For 
    example, as part of the post-construction minimum measure, EPA 
    recommends that municipalities consider policies and ordinances that 
    encourage infill development in higher density urban areas, and areas 
    with existing infrastructure, in order to meet the measure's intent.
        EPA also received several comments expressing concern that 
    incorporating ``smart growth'' incentives threatened the autonomy of 
    local governments. One commenter was worried that ``incentives'' could 
    become more onerous than the minimum measures. EPA is very aware of 
    municipal concerns about possible federal interference with local land 
    use planning. EPA is also cognizant of the difficulty surrounding 
    incentives for ``smart growth'' activities due to these concerns. 
    However, the Agency believes it has addressed these concerns by 
    proposing a flexible approach and will continue to support the concept 
    of ``smart growth'' by encouraging policies that limit the adverse 
    impacts of growth and development on water quality.
    3. Provide Financial Assistance
        Although Congress has not established a fund to fully finance 
    implementation of the proposed extension of the existing NPDES storm 
    water program under CWA section 402(p)(6), numerous federal financing 
    programs (administered by EPA and other federal agencies) can provide 
    some financial assistance. The primary funding mechanism is the Clean 
    Water State Revolving Fund (SRF) program, which provides sources of 
    low-cost financing for a range of water quality infrastructure 
    projects, including storm water. In addition to the SRF, federal 
    financial assistance programs include the Water Quality Cooperative 
    Agreements under CWA section 104(b)(3), Water Pollution Control Program 
    grants to States under CWA section 106, and the Transportation Equity 
    Act for the 21st Century (TEA-21) among others. In addition, Section 
    319 funds may be used to fund any urban storm water activities that are 
    not specifically required by a draft or final NPDES permit. EPA will 
    develop a list of potential funding sources as part of the tool box 
    implementation effort. EPA anticipates that some of these programs will 
    provide funds to help develop and, in limited circumstances, implement 
    the CWA section 402(p)(6) storm water discharge control program.
        EPA received numerous comments that requested additional funding. 
    Congress provided one substantial new source of potential funding for 
    transportation related storm water projects--TEA-21. The Department of 
    Transportation has included a number of water-related provisions in its 
    TEA-21 planning. These include Transportation Enhancements, 
    Environmental Restoration and Pollution Abatement, and Environmental 
    Streamlining. More information on TEA-21 is available at the following 
    internet sites: www.fhwa.dot.gov/tea21/outreach.htm and www.tea21.org.
    4. Implement the Program in Jurisdictions Not Authorized To Administer 
    the NPDES Program
        Because today's final rule uses the NPDES framework, EPA will be 
    the NPDES permitting authority in several States, Tribal jurisdictions, 
    and Territories. As such, EPA will have the same responsibilities as 
    any other NPDES permitting authority--issuing permits, designating 
    additional sources, and taking appropriate enforcement actions--and 
    will seek to tailor the storm water discharge control program to the 
    specific needs in that State, Tribal jurisdiction, or Territory. EPA 
    also plans to provide support and oversight, including outreach, 
    training, and technical assistance to the regulated communities. 
    Section II.G. of today's preamble provides a separate discussion 
    related to the NPDES permitting authority's responsibilities for 
    today's final rule.
    5. Oversee State and Tribal Programs
        Under the NPDES program, EPA plays an oversight role for NPDES-
    approved States and Tribes. In this role, EPA and the State or Tribe 
    work together to implement, enforce, and improve the NPDES program. 
    Part of this oversight role includes working with States and Tribes to 
    modify their programs where programmatic or implementation concerns 
    impede program effectiveness. This role will be vitally important when 
    States and Tribes make adjustments to develop, implement, and enforce 
    today's extension of the existing NPDES storm water discharge control 
    program. In addition, States maintain a continuing planning process 
    (CPP) under CWA section 303(e), which EPA periodically reviews to 
    assess the program's achievements.
        In its oversight role, EPA takes action to address States and 
    Tribes who have obtained NPDES authorization but are not fulfilling 
    their obligations under the NPDES program. If an NPDES-authorized State 
    or Tribe fails to implement an adequate NPDES storm water program, for 
    example, EPA typically enters into extensive discussions to resolve 
    outstanding issues. EPA has the authority to withdraw the entire NPDES 
    program when resolution cannot be reached. Partial program withdrawal 
    is not provided for under the CWA except for partial approvals.
        EPA is also working with the States and Tribes to improve nonpoint 
    source management programs and assessments to incorporate key program 
    elements. Key nonpoint source program elements include setting short 
    and long term goals and objectives; establishing public and private 
    partnerships; using a balanced approach incorporating Statewide and 
    watershed-wide abatement of existing impairments; preventing future 
    impairments; developing processes to address both impaired and 
    threatened waters; reviewing and upgrading all program components, 
    including program revisions on a 5-year cycle; addressing federal land 
    management and activities inconsistent with State programs; and 
    managing State nonpoint source management programs effectively.
        In particular, EPA works with the States and Tribes to strengthen 
    their nonpoint source pollution programs to address all significant 
    nonpoint sources, including agricultural sources, through the CWA 
    section 319 program. EPA is working with other government agencies, as 
    well as with community groups, to effect voluntary changes regarding 
    watershed protection and reduced nonpoint source pollution.
        In addition, EPA and NOAA have published programmatic and technical 
    guidance to address coastal nonpoint source pollution. Under Section 
    6217 of the CZARA, States are developing and implementing coastal 
    nonpoint pollution control programs approved by EPA and NOAA.
    
    [[Page 68743]]
    
    6. Comply With Applicable Requirements as a Discharger
        Today's final rule covers federally operated facilities in a 
    variety of ways. These facilities are generally areas where people 
    reside, such as a federal prison, hospital, or military base. It also 
    includes federal parkways and road systems with separate storm sewer 
    systems. Today's rule requires federal MS4s to comply with the same 
    application deadlines that apply to regulated small MS4s generally. EPA 
    believes that all federal MS4s serve populations of less than 100,000.
        EPA received several comments that asked if individual buildings 
    like post offices are considered to be small MS4s and thereby regulated 
    in today's rule if they are in an urbanized area. Most of these 
    buildings have at most a parking lot with runoff or a storm sewer that 
    connects with a municipality's MS4. EPA does not intend that individual 
    federal buildings be considered to be small MS4s. This is discussed in 
    section II.H.2.b. of today's preamble.
        Federal facilities can also be included under requirements 
    addressing storm water discharges associated with small construction 
    activities. In any case, discharges from these facilities will need to 
    comply with all applicable NPDES requirements and any additional water 
    quality-related requirements imposed by a State, Tribal, or local 
    government. Failure to comply can result in enforcement actions. 
    Federal facilities can act as models for municipal and private sector 
    facilities and implement or test state-of-the-art management practices 
    and control measures.
    
    E. State Role
    
        Today's final rule sets forth an NPDES approach for implementing 
    the extension of the existing storm water discharge control program 
    under CWA section 402(p)(6). State assumption of the NPDES program is 
    voluntary, consistent with the principles of federalism. Because most 
    States are approved to implement the NPDES program, they will tailor 
    their storm water discharge control programs to address their water 
    quality needs and objectives. While today's rule establishes the basic 
    framework for the section 402(p)(6) program, States as well as Tribes 
    (see discussion in section II.F) have an important role in fine-tuning 
    the program to address the water quality issues within their 
    jurisdictions. The basic framework allows for adjustments based on 
    factors that vary geographically, including climate patterns and 
    terrain.
        Where States do not have NPDES authority, they are not required to 
    implement the storm water discharge control program, but they may still 
    participate in water quality protection through participation in the 
    CWA section 401 certification process (for any permits) and through 
    development of water quality standards and TMDLs.
    1. Develop the Program
        In expanding the existing NPDES program for storm water discharges, 
    States must evaluate whether revisions to their NPDES programs are 
    necessary. If so, modifications must be made in accordance with 
    Sec. 123.62. Under Sec. 123.62, States must revise their NPDES programs 
    within 1 year, or within 2 years if statutory changes are necessary.
        Some States and departments of transportation (DOTs) commented that 
    this timeframe is too short, anticipating that the State legislative 
    process and the modification of regulations combined would take beyond 
    2 years. The deadline language in Sec. 123.62 is not new language for 
    the storm water discharge control program; it applies to all NPDES 
    programs. EPA believes the vast majority of States will meet the 
    deadline and will work with States in those cases where there may be 
    difficulty meeting this deadline due to the timing of legislative 
    sessions and the regulatory development process.
        An authorized State NPDES program must meet the requirements of CWA 
    section 402(b) and conform to the guidelines issued under CWA section 
    304(i)(2). Today's final rule under Sec. 123.25 adds specific cross 
    references to the storm water discharge control program components to 
    ensure that States adequately address these requirements.
    2. Comply With Applicable Requirements as a Discharger
        Today's final rule covers State operated separate storm sewer 
    systems in a variety of ways. These systems generally drain areas where 
    people reside, such as a prison, hospital, or other populated facility. 
    These systems are included under the definition of a regulated small 
    MS4, which specifically identifies systems operated by State 
    departments of transportation. Alternatively, storm water discharges 
    from State activities may be regulated under the section addressing 
    storm water discharges associated with small construction activities. 
    In any case, discharges from these facilities must comply with all 
    applicable NPDES requirements. Failure to comply can result in 
    enforcement actions. State facilities can act as models for municipal 
    and private sector facilities and implement or test state-of-the-art 
    management practices and control measures.
    3. Communicate With EPA
        Under approved NPDES programs, States have an ongoing obligation to 
    share information with EPA. This dialogue is particularly important in 
    the CWA section 402(p)(6) storm water program where these governments 
    continue to develop a great deal of the guidance and outreach related 
    to water quality.
    
    F. Tribal Role
    
        The proposal to today's final rule provides background information 
    on EPA's 1984 Indian Policy and the criteria for treatment of an Indian 
    Tribe in the same manner as a State. Today's final rule extends the 
    existing NPDES program for storm water discharges to two types of 
    dischargers located in Indian country. First, the final rule designates 
    storm water discharges from any regulated small MS4, including Tribal 
    systems. Second, the final rule regulates discharges associated with 
    construction activity disturbing between one and five acres of land, 
    including sites located in Indian country. Operators in each of these 
    categories of regulated activity must apply for coverage under an NPDES 
    permit by 3 years and 90 days from the date of publication of today's 
    final rule. Under existing regulations, however, EPA or an authorized 
    NPDES Tribe may require a specified storm water discharger to apply for 
    NPDES permit coverage before this deadline based on a determination 
    that the discharge is contributing to a violation of a water quality 
    standard (including designated uses) or is a significant contributor of 
    pollutants.
        Under today's rule, a Tribal governmental entity may regulate storm 
    water discharges on its reservation in two ways--as either an NPDES-
    authorized Tribe or as a regulated MS4. If a Tribe is authorized to 
    operate the NPDES program, the Tribe must implement today's final rule 
    for the NPDES program for storm water for covered dischargers located 
    within the EPA recognized boundaries. Otherwise, EPA is generally the 
    permitting/program authority within Indian country. Discussions about 
    the State Role in the preceding section also apply to NPDES authorized 
    Tribes. For additional information on the role and responsibilities of 
    the permitting authority in the NPDES storm water program, see 
    Sec. 123.35 (and Section II.G. of today's preamble) and Sec. 123.25(a).
    
    [[Page 68744]]
    
        Under today's final rule, if the Indian reservation is located 
    entirely or partially within an ``urbanized area,'' as defined in 
    Sec. 122.32(a)(1), the Tribe must obtain an NPDES permit if it operates 
    a small MS4 within the urbanized area portion. Tribal MS4s located 
    outside an urbanized area are not automatically covered, but may be 
    designated by EPA pursuant to Sec. 122.32(a)(2) of today's rule or may 
    request designation as a regulated small MS4 from EPA. A Tribe that is 
    a regulated MS4 for NPDES program purposes is required to implement the 
    six minimum control measures to the extent allowable under Federal law.
        The Tribal representative on the Storm Water Phase II FACA 
    Subcommittee asked EPA to provide a list of the Tribes located in 
    urbanized areas that would fall within the NPDES storm water program 
    under today's final rule. In December 1996, EPA developed a list of 
    federally recognized American Indian Areas located wholly or partially 
    in Bureau of the Census-designated urbanized areas (see Appendix 1). 
    Appendix 1 not only provides a listing of reservations and individual 
    Tribes, but also the name of the particular urbanized area in which the 
    reservation is located and an indication of whether the urbanized area 
    contains a medium or large MS4 that is already covered by the existing 
    Phase I regulations.
        Some of the Tribes listed in Appendix 1 are only partially located 
    in an urbanized area. If the Tribe's MS4 serves less than 1,000 people 
    within an urbanized area, the permitting authority may waive the 
    Tribe's MS4 storm water requirements if it meets the conditions of 
    Sec. 122.32(c). EPA does not have information on the Tribal populations 
    within the urbanized areas, so it can not identify the Tribes that are 
    eligible for a waiver. Therefore, a Tribe that believes it qualifies 
    for a waiver should contact its permitting authority.
    
    G. NPDES Permitting Authority's Role for the NPDES Storm Water Small 
    MS4 Program
    
        As noted previously, the NPDES permitting authority can be EPA or 
    an authorized State or an authorized Tribe. The following discussion 
    describes the role of the NPDES permitting authority under today's 
    final rule.
    1. Comply With Implementation Requirements
        NPDES permitting authorities must perform certain duties to 
    implement the NPDES storm water municipal program. Section 123.35(a) of 
    today's final rule emphasizes that permitting authorities have existing 
    obligations under the NPDES program. Section 123.35 focuses on specific 
    issues related to the role of the NPDES authority to support 
    administration and implementation of the municipal storm water program 
    under CWA section 402(p)(6).
    2. Designate Sources
        Section 123.35(b) of today's final rule addresses the requirements 
    for the NPDES permitting authority to designate sources of storm water 
    discharges to be regulated under Secs. 122.32 through 122.36. NPDES 
    permitting authorities must develop a process, as well as criteria, to 
    designate small MS4s. They must also have the authority to designate a 
    small MS4 if and when circumstances that support a waiver under 
    Sec. 122.32(c) change. EPA may make designations if an NPDES-approved 
    State or Tribe fails to do so.
        NPDES permitting authorities must examine geographic jurisdictions 
    that they believe should be included in the storm water discharge 
    control program but are not located in an ``urbanized area''. Small 
    MS4s in these areas are not designated automatically. Discharges from 
    such areas should be brought into the program if found to have actual 
    or potential exceedances of water quality standards, including 
    impairment of designated uses, or other adverse impacts on water 
    quality, as determined by local conditions or watershed and TMDL 
    assessments. EPA's aim is to address discharges to impaired waters and 
    to protect waters with the potential for problems. EPA encourages NPDES 
    permitting authorities, local governments, and the interested public to 
    work together in the context of a watershed plan to address water 
    quality issues, including those associated with municipal storm water 
    runoff.
        EPA received comments stating that the process of developing 
    criteria and applying it to all MS4s outside an urbanized area serving 
    a population of 10,000 or greater and with a density of 1,000 people 
    per square mile is too time-consuming and resource-intensive. These 
    commenters believe that the permitting authority should decide which 
    MS4s must be brought into the storm water discharge control program and 
    that population and density should not be an overriding criteria. One 
    suggested way of doing so was to only designate MS4s with demonstrated 
    contributions to the impairment of water quality uses as shown by a 
    TMDL. EPA disagrees with this suggestion. The TMDL process is time-
    consuming. MS4s outside of urbanized areas may cause water quality 
    problems long before a TMDL is completed.
        EPA believes that permitting authorities should consider the 
    potential water quality impacts of storm water from all jurisdictions 
    with a population of 10,000 or greater and a density of 1,000 people 
    per square mile. EPA is using data summarized in the NURP study and in 
    the CWA section 305(b) reports to support this approach for targeted 
    designation outside of urbanized areas. EPA is not mandating which 
    criteria are to be used, but has provided examples of criteria that may 
    be useful in evaluating potential water quality impacts. EPA believes 
    that the flexibility provided in this section of today's final rule 
    allows the permitting authority to develop criteria and a designation 
    process that is easy to use and protects water quality. Therefore, the 
    provisions of Sec. 123.35(b) remain as proposed.
    a. Develop Designation Criteria
        Under Sec. 123.35(b), the NPDES permitting authority must establish 
    designation criteria to evaluate whether a storm water discharge 
    results in or has the potential to result in exceedances of water 
    quality standards, including impairment of designated uses, or other 
    significant water quality impacts, including adverse habitat and 
    biological impacts.
        EPA recommends that NPDES permitting authorities consider, in a 
    balanced manner, certain locally-focused criteria for designating any 
    MS4 located outside of an urbanized area on the basis of significant 
    water quality impacts. EPA recommends consideration of criteria such as 
    discharge to sensitive waters, high growth or growth potential, high 
    population density, contiguity to an urbanized area, significant 
    contribution of pollutants to waters of the United States, and 
    ineffective control of water quality concerns by other programs. These 
    suggested designation criteria are intended to help encourage the 
    permitting authority to use an objective method for identifying and 
    designating, on a local basis, sources that adversely impact water 
    quality. More information about these criteria and the reasons why they 
    are suggested by EPA is included in the January 9, 1998, proposal (63 
    FR 1561) for today's final rule.
        The suggested criteria are meant to be taken in the aggregate, with 
    a great deal of flexibility as to how each should be weighed in order 
    to best account for watershed and other local conditions and to allow 
    for a more tailored case-by-case analysis. The application of criteria 
    is meant to be geographically specific. Furthermore, each criterion 
    does not have to be met in order for a small MS4
    
    [[Page 68745]]
    
    to qualify for designation, nor should an MS4 necessarily be designated 
    on the basis of one or two criteria alone.
        EPA believes that the application of the recommended designation 
    criteria provides an objective indicator of real and potential water 
    quality impacts from urban runoff on both the local and watershed 
    levels. EPA encourages the application of the recommended criteria in a 
    watershed context, thereby allowing for the evaluation of the water 
    quality impacts of the portions of a watershed outside of an urbanized 
    area. For example, situations exist where the urbanized area represents 
    a small portion of a degraded watershed, and the adjacent nonurbanized 
    areas of the watershed have significant cumulative effects on the 
    quality of the receiving waters.
        EPA received numerous suggestions of additional criteria that 
    should be added and reasons why some of the criteria in the proposal to 
    today's final rule were not appropriate. EPA developed its suggested 
    designation criteria based on findings of the NURP study and other 
    studies that indicate pollutants of concern, including total suspended 
    solids, chemical oxygen demand, and temperature. These criteria were 
    the subject of considerable discussion by the Storm Water Phase II FACA 
    Subcommittee. EPA developed them in response to recommendations from 
    the subcommittee during development of the proposed rule. The listed 
    criteria are only suggestions. Permitting authorities are required to 
    develop their own criteria. EPA has not found any reason to change its 
    suggested list of criteria and the suggestions remain as proposed.
    b. Apply Designation Criteria
        After customizing the designation criteria for local conditions, 
    the permitting authority must apply such criteria, at a minimum, to any 
    MS4 located outside of an urbanized area serving a jurisdiction with a 
    population of at least 10,000 and a population density of 1,000 people 
    per square mile or greater (see Sec. 123.35(b)(2)). If the NPDES 
    permitting authority determines that an MS4 meets the criteria, the 
    permitting authority must designate it as a regulated small MS4. This 
    designation must occur within 3 years of publication of today's final 
    rule. Alternatively, the NPDES authority can designate within 5 years 
    from the date of final regulation if the designation criteria are 
    applied on a watershed basis where a comprehensive watershed plan 
    exists (a comprehensive watershed plan is one that includes the 
    equivalents of TMDLs) (see Sec. 123.35(b)(3)). The extended 5 year 
    deadline is intended to provide incentives for watershed-based 
    designations. If an NPDES-authorized State or Tribe does not develop 
    and apply designation criteria within this timeframe, then EPA has the 
    opportunity to do so in lieu of the authorized State or Tribe.
        NPDES permitting authorities can designate any small MS4, including 
    one below 10,000 in population and 1,000 in density. EPA established 
    the 10,000/1,000 threshold based on the likelihood of adverse water 
    quality impacts at these population and density levels. In addition, 
    the 1,000 persons per square mile threshold is consistent with both the 
    Bureau of the Census definition of an ``urbanized area'' (see Section 
    II.H.2. below) and stakeholder discussions concerning the definition of 
    a regulated small MS4.
        One commenter requested that EPA develop interim deadlines for 
    development of designation criteria. EPA believes that the designation 
    deadline identified in today's final rule at Sec. 123.35(b)(3) provides 
    States and Tribes with a flexibility that allows them to develop and 
    apply the criteria locally in a timely fashion, while at the same time 
    establishing an expeditious deadline.
     c. Designate Physically Interconnected Small MS4s
        In addition to applying criteria on a local basis for potential 
    designation, the NPDES permitting authority must designate any MS4 that 
    contributes substantially to the pollutant loadings of a physically 
    interconnected municipal separate storm sewer that is regulated by the 
    NPDES program for storm water discharges (see Sec. 123.35(b)(4)). To be 
    ``physically interconnected,'' the MS4 of one entity, including roads 
    with drainage systems and municipal streets, is physically connected 
    directly to the municipal separate storm sewer of another entity. This 
    provision applies to all MS4s located outside of an urbanized area. EPA 
    added this section in recognition of the concerns of local government 
    stakeholders that a local government should not have to shoulder total 
    responsibility for a storm water program when storm water discharges 
    from another MS4 are also contributing pollutants or adversely 
    affecting water quality. This provision also helps to provide some 
    consistency among MS4 programs and to facilitate watershed planning in 
    the implementation of the NPDES storm water program. EPA recommended 
    physical interconnectedness in the existing NPDES storm water 
    regulations as a factor for consideration in the designation of 
    additional sources.
        Today's final rule does not include interim deadlines for 
    identifying physically interconnected MS4s. However, consistent with 
    the deadlines identified in Sec. 123.35(b)(3) of today's final rule, 
    EPA encourages the permitting authority to make these determinations 
    within 3 years from the date of publication of the final rule or within 
    5 years if the permitting authority is implementing a comprehensive 
    watershed plan. Alternatively, the affected jurisdiction could use the 
    petition process under 40 CFR 122.26(f) in seeking to have the 
    permitting authority designate the contributing jurisdiction.
        Several commenters expressed concerns about who could be designated 
    under this provision (Sec. 123.35(b)(4)). One commenter requested that 
    the word ``substantially'' be deleted from the rule because they 
    believe any MS4 that contributes at all to a physically interconnected 
    municipal separate storm sewer should be regulated. EPA believes that 
    the word ``substantially'' provides necessary flexibility to the 
    permitting authorities. The permitting authority can decide if an MS4 
    is contributing discharges to another municipal separate storm sewer in 
    a manner that requires regulation. If the operator of a regulated 
    municipal separate storm sewer believes that some of its pollutant 
    loadings are coming from an unregulated MS4, it can petition the 
    permitting authority to designate the unregulated MS4 for regulation.
    d. Respond to Public Petitions for Designation
        Today's final rule reiterates the existing opportunity for the 
    public to petition the permitting authority for designation of a point 
    source to be regulated to protect water quality. The petition 
    opportunity also appears in existing NPDES regulations at 40 CFR 
    122.26(f). Any person may petition the permitting authority to require 
    an NPDES permit for a discharge composed entirely of storm water that 
    contributes to a violation of a water quality standard or is a 
    significant contributor of pollutants to the waters of the United 
    States (see Sec. 123.32(b)). The NPDES permitting authority must make a 
    final determination on any petition within 180 days after receiving the 
    petition (see Sec. 123.35(c)). EPA believes that a 180 day limit 
    balances the public's need for a timely final determination with the 
    NPDES permitting authority's need to prioritize its workload. If an 
    NPDES-approved State or Tribe fails to act
    
    [[Page 68746]]
    
    within the 180-day timeframe, EPA may make a determination on the 
    petition. EPA believes that public involvement is an important 
    component of the NPDES program for storm water and feels that this 
    provision encourages public participation. Section II.K, Public 
    Involvement/Public Role, further discusses this topic.
    3. Provide Waivers
        Today's rule provides two opportunities for the NPDES permitting 
    authority to exempt certain small MS4s from the need for a permit based 
    on water quality considerations. See Secs. 122.32(d) and (e). The two 
    waiver opportunities have different size thresholds and take different 
    approaches to considering the water quality impacts of discharges from 
    the MS4.
        In the proposal, EPA requested comment on the option of waiving 
    coverage for all MS4s with less than 1,000 people unless the permitting 
    authority determined that the small MS4 should be regulated based on 
    significant adverse water quality impacts. A number of commenters 
    supported this option. They expressed concern that compliance with the 
    rule requirements and certification of one of the waiver provisions 
    were both costly for very small communities. They stated that the 
    permitting authority should identify a water quality problem before 
    requiring compliance. Today's rule essentially adopts this alternative 
    approach for MS4s serving a population under 1,000.
        The final rule has expanded the waiver provision that EPA proposed 
    for small MS4s with a population less than 1,000. The proposed rule 
    would have required a small MS4 operator to certify that storm water 
    controls are not needed based on either wasteload allocations that are 
    part of TMDLs that address the pollutants of concern, or a 
    comprehensive watershed plan implemented for the waterbody that 
    includes the equivalents of TMDLs and addresses the pollutant(s) of 
    concern. Commenters noted that the proposed waivers would be 
    unattainable if a TMDL or equivalent analysis was required for every 
    pollutant that could possibly be present in any amount in discharges 
    from an MS4 regardless of whether the pollutant is causing water 
    quality impairment. Commenters asked that EPA identify what constitutes 
    the ``pollutant(s) of concern'' for which a TMDL or its equivalent must 
    be developed. For example, Sec. 122.30(c) indicates that the MS4 
    program is intended to control ``sediment, suspended solids, nutrients, 
    heavy metals, pathogens, toxins, oxygen-demanding substances, and 
    floatables.'' Commenters asked whether TMDLs or equivalent analyses 
    have to address all of these.
        EPA has revised the proposed waiver in response to these concerns. 
    Under today's rule, NPDES permitting authorities may waive the 
    requirements of today's rule for any small MS4 with a population less 
    than 1,000 that does not contribute substantially to the pollutant 
    loadings of a physically interconnected MS4, unless the small MS4 
    discharges pollutants that have been identified as a cause of 
    impairment of the waters to which the small MS4 discharges. If the 
    small MS4 does discharge pollutants that have been identified as 
    impairing the water body into which the small MS4 discharges, the NPDES 
    permitting authority may grant a waiver only if it determines that 
    storm water controls are not needed based on an EPA approved or 
    established TMDL that addresses the pollutant(s) of concern.
        Unlike the proposed rule, Sec. 122.32(d) does not allow the waiver 
    for MS4s serving a population under 1,000 to be based on ``the 
    equivalent of a TMDL.'' Because Sec. 122.32(d) requires a pollutant 
    specific analysis only for a pollutant that has been identified as a 
    cause of impairment, a TMDL is required for such pollutant before the 
    waiver may be granted. Once a pollutant has been identified as the 
    cause of impairment of a water body, the State should develop a TMDL 
    for that pollutant for that water body. Thus, Sec. 122.32(d) takes a 
    different approach than that taken for the waiver in Sec. 122.32(e) for 
    MS4s serving a population under 10,000, which can be based upon an 
    analysis that is ``the equivalent of a TMDL.'' This is because 
    Sec. 122.32(d) requires an analysis to support the waiver for MS4s 
    under 1,000 only if a waterbody to which the MS4 discharges has been 
    identified as impaired. The Sec. 122.32(e) waiver, on the other hand, 
    would be available for larger MS4s but only after the State 
    affirmatively establishes lack of impairment based upon a comprehensive 
    analysis of smaller urban waters that might not otherwise be evaluated 
    for the purposes of CWA section 303. Since Sec. 122.32(e) requires the 
    analysis of waters that have not been identified as impaired, an actual 
    TMDL is not required and an analysis that is the equivalent of a TMDL 
    can suffice to support the waiver.
        Where a State is the NPDES permitting authority, the permitting 
    authority is responsible for the development of the TMDLs as well as 
    the assessment of the extent to which a small MS4's discharge 
    contributes pollutants to a neighboring regulated system. In States 
    where EPA is the permitting authority, EPA will use a State's TMDLs to 
    determine whether storm water controls are required for the small MS4s.
        The proposed rule would have required the operator of the small MS4 
    serving a population under 1,000 to certify that its discharge was 
    covered under a TMDL that indicated that discharges from its particular 
    system were not having an adverse impact on water quality (i.e., it was 
    either not assigned wasteload allocations under TMDLs or its discharge 
    is within an assigned allocation). Many commenters expressed concerns 
    that MS4 operators serving less than 1,000 persons may lack the 
    technical capacity to certify that their discharges are not 
    contributing to adverse water quality impacts. These commenters thought 
    that the permitting authority should make such a certification. Today's 
    rule provides flexibility as to how the waiver is administered. 
    Permitting authorities are ultimately responsible for granting the 
    waiver, but are free to determine whether or not to require small MS4 
    operators that are seeking waivers to submit information or a written 
    certification.
        Under Sec. 122.32(e) a State may grant a waiver to an MS4 serving a 
    population between 1,000 and 10,000 only if the State has made a 
    comprehensive effort to ensure that the MS4 will not cause or 
    contribute to water quality impairment. To grant a Sec. 122.32(e) 
    waiver, the NPDES permitting authority must evaluate all waters of the 
    U.S. that receive a discharge from the MS4 and determine that storm 
    water controls are not needed. The permitting authority's evaluation 
    must be based on wasteload allocations that are part of an EPA approved 
    or established TMDL or, if a TMDL has not been developed or approved, 
    an equivalent analysis that determines sources and allocations for the 
    pollutant(s) of concern. The pollutants of concern that the permitting 
    authority must evaluate include biochemical oxygen demand (BOD), 
    sediment or a parameter that addresses sediment (such as total 
    suspended solids, turbidity or siltation), pathogens, oil and grease, 
    and any other pollutant that has been identified as a cause of 
    impairment of any water body that will receive a discharge from the 
    MS4. Finally, the permitting authority must have determined that future 
    discharges from the MS4 do not have the potential to result in 
    exceedances of water quality standards, including impairment of 
    designated uses, or other significant
    
    [[Page 68747]]
    
    water quality impacts, including habitat and biological impacts.
        Although EPA did not propose this specific approach, the Agency did 
    request comment on whether to increase the proposed 1,000 population 
    threshold for a waiver. The Sec. 122.32(e) waiver was developed in 
    response to comments, including States' concerns that they needed 
    greater flexibility to focus their efforts on MS4s that were causing 
    water quality impairment. Several commenters thought that the threshold 
    should be increased from 1,000 to 5,000 or 10,000. Others suggested 
    additional ways of qualifying for a waiver for MS4s that discharge to 
    waters that are not covered by a TMDL or watershed plan. EPA carefully 
    considered all the options for expanding the waiver provisions and has 
    decided to expand the waiver only in the very narrow circumstances 
    described above where a comprehensive analysis has been undertaken to 
    demonstrate that the MS4 is not causing water quality impairment.
        The NPDES permitting authority can, at any time, mandate compliance 
    with program requirements from a previously waived small MS4 if 
    circumstances change. For example, a waiver can be withdrawn in 
    circumstances where the permitting authority later determines that a 
    waived small MS4's storm water discharge to a small stream will cause 
    adverse impacts to water quality or significantly interfere with 
    attainment of water quality standards. A ``change in circumstances'' 
    could involve receipt of new information. Changed circumstances can 
    also allow a regulated small MS4 operator to request a waiver at any 
    time.
        Some commenters expressed concerns about allowing any small MS4 
    waivers. One commenter stated that storm water pollution prevention 
    plans are necessary to control storm water pollution and should be 
    required from all regulated small MS4s. For the reasons stated in the 
    Background section above, EPA agrees that the discharges from most MS4s 
    in urbanized areas should be addressed by a storm water management 
    program outlined in today's rule. For MS4s serving very small areas, 
    however, the TMDL development process provides an opportunity to 
    determine whether an MS4 serving a population less than 1,000 is having 
    a negative impact on any receiving water that is impaired by a 
    pollutant that the MS4 discharges. MS4s serving populations up to 
    10,000 may receive a waiver only if a comprehensive analysis of its 
    impact on receiving water has been performed.
        Other commenters said that waivers should not be allowed for small 
    MS4s that discharge into another regulated MS4. These commenters stated 
    that the word ``substantially'' should be removed from 
    Sec. 122.32(d)(i) so that a waiver would not be allowed for any system 
    ``contributing to the storm water pollutant loadings of a physically 
    interconnected regulated MS4.'' As previously mentioned under the 
    designation discussion of section II.G.2.c, EPA believes that the word 
    ``substantially'' provides needed flexibility to the permitting 
    authorities. It is important to note that this is only one aspect that 
    the permitting authority must consider when deciding on the 
    appropriateness of a waiver.
    4. Issue Permits
        NPDES permitting authorities have a number of responsibilities 
    regarding the permit process. Sections 123.35(d) through (g) ensure a 
    certain level of consistency for permits, yet provide numerous 
    opportunities for flexibility. NPDES permitting authorities must issue 
    NPDES permits to cover municipal sources to be regulated under 
    Sec. 122.32, unless waived under Sec. 122.32(c). EPA encourages 
    permitting authorities to use general permits as the vehicle for 
    permitting and regulating small MS4s. The Agency notes, however, that 
    some operators may wish to take advantage of the option to join as a 
    co-permittee with an MS4 regulated under the existing NPDES storm water 
    program.
        Today's final rule includes a provision, Sec. 123.35(f), that 
    requires NPDES permitting authorities to either include the 
    requirements in Sec. 122.34 for NPDES permits issued for regulated 
    small MS4s or to develop permit limits based on a permit application 
    submitted by a small MS4. See Section II.H.3.a, Minimum Control 
    Measures, for more details on the actual Sec. 122.34 requirements. See 
    Section II.H.3.c for alternative and joint permitting options.
        In an attempt to avoid duplication of effort, Sec. 122.34(c) allows 
    NPDES permitting authorities to include permit conditions that direct 
    an MS4 to meet the requirements of a qualifying local, Tribal, or State 
    municipal storm water management program. For a local, Tribal, or State 
    program to ``qualify,'' it must impose, at a minimum, the relevant 
    requirements of Sec. 122.34(b). A regulated small MS4 must still follow 
    the procedural requirements for an NPDES permit (i.e., submit an 
    application, either an individual application or an NOI under a general 
    permit) but will instead follow the substantive pollutant control 
    requirements of the qualifying local, Tribal, or State program.
        Under Sec. 122.35(b), NPDES permitting authorities may also 
    recognize existing responsibilities among governmental entities for the 
    minimum control measures in an NPDES small MS4 storm water permit. For 
    example, the permit might acknowledge the existence of a State 
    administered program that addresses construction site runoff and 
    require that the municipalities only develop substantive controls for 
    the remaining minimum control measures. By acknowledging existing 
    programs, this provision is meant to reduce the duplication of efforts 
    and to increase the flexibility of the NPDES storm water program.
        Section 123.35(e) of today's final rule requires permitting 
    authorities to specify a time period of up to 5 years from the issuance 
    date of an NPDES permit for regulated small MS4 operators to fully 
    develop and implement their storm water programs. As discussed more 
    fully below, permitting authorities should be providing extensive 
    support to the local governments to assist them in developing and 
    implementing their programs.
        In the proposed rule, EPA stated that the permitting authority 
    would develop the menu of BMPs and if they failed to do so, EPA would 
    develop the menu. Commenters felt that EPA should develop a menu of 
    BMPs, rather than just providing guidance. In the settlement agreement 
    for seeking an extension to the deadline for issuing today's rule, EPA 
    committed to developing a menu of BMPs by October 27, 2000. Permitting 
    authorities can adopt EPA's menu or develop their own. The menu itself 
    is not intended to replace more comprehensive BMP guidance materials. 
    As part of the tool box efforts, EPA will provide separate guidance 
    documents that discuss the results from EPA-sponsored nationwide 
    studies on the design, operation and maintenance of BMPs. Additionally, 
    EPA expects that the new rulemaking on construction BMPs may provide 
    more specific design, operation and maintenance criteria.
    5. Support and Oversee the Local Programs
        NPDES permitting authorities are responsible for supporting and 
    overseeing the local municipal programs. Section 123.35(h) of today's 
    final rule highlights issues associated with these responsibilities.
        To the extent possible, NPDES permitting authorities should provide 
    financial assistance to MS4s, which
    
    [[Page 68748]]
    
    often have limited resources, for the development and implementation of 
    local programs. EPA recognizes that funding for programs at the State 
    and Tribal levels may also be limited, but strongly encourages States 
    and Tribes to provide whatever assistance is possible. In lieu of 
    actual dollars, NPDES permitting authorities can provide cost-cutting 
    assistance in a number of ways. For example, NPDES permitting 
    authorities can develop outreach materials for MS4s to distribute or 
    the NPDES permitting authority can actually distribute the materials. 
    Another option is to implement an erosion and sediment control program 
    across an entire State (or Tribal land), thus alleviating the need for 
    the MS4 to implement its own program. The NPDES permitting authority 
    must balance the need for site-specific controls, which are best 
    handled by a local MS4, with its ability to offer financial assistance. 
    EPA, States, Tribes, and MS4s should work as a team in making these 
    kinds of decisions.
        NPDES permitting authorities are responsible for overseeing the 
    local programs. Permitting authorities should work with the regulated 
    community and other stakeholders to assist in local program development 
    and implementation. This might include sharing information, analyzing 
    reports, and taking enforcement actions, as necessary. NPDES permitting 
    authorities play a vital role in supporting local programs by providing 
    technical and programmatic assistance, conducting research projects, 
    and monitoring watersheds. The NPDES permitting authority can also 
    assist the MS4 permittee in obtaining adequate legal authority at the 
    local level in order to implement the local component of the CWA 
    section 402(p)(6) program.
        NPDES permitting authorities are encouraged to coordinate and 
    utilize the data collected under several programs. States and Tribes 
    address point and nonpoint source storm water discharges through a 
    variety of programs. In developing programs to carry out CWA section 
    402(p)(6), EPA recommends that States and Tribes coordinate all of 
    their water pollution evaluation and control programs, including the 
    continuing planning process under CWA section 303(e), the existing 
    NPDES program, the CZARA program, and nonpoint source pollution control 
    programs.
        In addition, NPDES permitting authorities are encouraged to provide 
    a brief (e.g., two-page) reporting format to facilitate compilation and 
    analysis of data from reports submitted under Sec. 122.34(g)(3). EPA 
    intends to develop a model form for this purpose.
    
    H. Municipal Role
    
    1. Scope of Today's Rule
        Today's final rule attempts to establish an equitable and 
    comprehensive four-pronged approach for the designation of municipal 
    sources. First, the approach defines for automatic coverage the 
    municipal systems believed to be of highest threat to water quality. 
    Second, the approach designates municipal systems that meet a set of 
    objective criteria used to measure the potential for water quality 
    impacts. Third, the approach designates on a case-by-case basis 
    municipal systems that ``contribute substantially to the pollutant 
    loadings of a physically-interconnected [regulated] MS4.'' Finally, the 
    approach designates on a case-by-case basis, upon petition, municipal 
    systems that ``contribute to a violation of a water quality standard or 
    are a significant contributor of pollutants.''
        Today's final rule automatically designates for regulation small 
    MS4s located in urbanized areas, and requires that NPDES permitting 
    authorities examine for potential designation, at a minimum, a 
    particular subset of small MS4s located outside of urbanized areas. 
    Today's rule also includes provisions that allow for waivers from the 
    otherwise applicable requirements for the smallest MS4s that are not 
    causing impairment of a receiving water body. Qualifications for the 
    waivers vary depending on whether the MS4 serves a population under 
    1,000 or a population under 10,000. See Secs. 122.32(d) and (e). These 
    waivers are discussed further in section II.G.3. Any small MS4 
    automatically designated by the final rule or designated by the 
    permitting authority under today's final rule is defined as a 
    ``regulated'' small MS4 unless it receives a waiver.
        In today's final rule, all regulated small MS4s must establish a 
    storm water discharge control program that meets the requirements of 
    six minimum control measures. These minimum control measures are public 
    education and outreach on storm water impacts, public involvement 
    participation, illicit discharge detection and elimination, 
    construction site storm water runoff control, post-construction storm 
    water management in new development and redevelopment, and pollution 
    prevention/good housekeeping for municipal operations.
        Today's rule allows for a great deal of flexibility in how an 
    operator of a regulated small MS4 is authorized to discharge under an 
    NPDES permit, by providing various options for obtaining permit 
    coverage and satisfying the required minimum control measures. For 
    example, the NPDES permitting authority can incorporate by reference 
    qualifying State, Tribal, or local programs in an NPDES general permit 
    and can recognize existing responsibilities among different 
    governmental entities for the implementation of minimum control 
    measures. In addition, a regulated small MS4 can participate in the 
    storm water management program of an adjoining regulated MS4 and can 
    arrange to have another governmental entity implement a minimum control 
    measure on their behalf.
    2. Municipal Definitions
    a. Municipal Separate Storm Sewer Systems (MS4s)
        The CWA does not define the term ``municipal separate storm 
    sewer.'' EPA defined municipal separate storm sewer in the existing 
    storm water permit application regulations to mean, in part, a 
    conveyance or system of conveyances (including roads with drainage 
    systems and municipal streets) that is ``owned or operated by a State, 
    city, town borough, county, parish, district, association, or other 
    public body * * * designed or used for collecting or conveying storm 
    water which is not a combined sewer and which is not part of a Publicly 
    Owned Treatment Works as defined at 40 CFR 122.2'' (see 
    Sec. 122.26(b)(8)(i)). Section 122.26 contains definitions of medium 
    and large municipal separate storm sewer systems but no definition of a 
    municipal separate storm sewer system, even though the term MS4 is 
    commonly used. In today's rule, EPA is adding a definition of municipal 
    separate storm sewer system and small municipal separate storm sewer 
    system along with the abbreviations MS4 and small MS4.
        The existing municipal permit application regulations define 
    ``medium'' and ``large'' MS4s as those located in an incorporated place 
    or county with a population of at least 100,000 (medium) or 250,000 
    (large) as determined by the latest Decennial Census (see 
    Secs. 122.26(b)(4) and 122.26(b)(7)). In today's final rule, these 
    regulations have been revised to define all medium and large MS4s as 
    those meeting the above population thresholds according to the 1990 
    Decennial Census.
        Today's rule also corrects the titles and contents of Appendices F, 
    G, H,& I to Part 122. EPA is adding those incorporated places and 
    counties whose 1990 population caused them to be defined as a 
    ``medium'' or ``large'' MS4. All of these MS4s have applied for
    
    [[Page 68749]]
    
    permit coverage so the effect of this change to the appendices is 
    simply to make them more accurate. They will not need to be revised 
    again because today's rule ``freezes'' the definition of ``medium'' and 
    ``large'' MS4s at those that qualify based on the 1990 census.
        EPA received several comments supporting and opposing the proposal 
    to ``freeze'' the definitions based on the 1990 census. Commenters who 
    disagreed with EPA's position cited the unfairness of municipalities 
    that reach the medium or large threshold at a later date having fewer 
    permitting requirements compared to those that were already at the 
    population thresholds when the existing storm water regulations took 
    effect. EPA recognizes this disparity but does not believe it is 
    unfair, as explained in the proposed rule. The decision was based on 
    the fact that the deadlines from the existing regulations have lapsed, 
    and because the permitting authority can always require more from 
    operators of MS4s serving ``newly over 100,000'' populations.
    b. Small Municipal Separate Storm Sewer Systems
        The proposal to today's final rule added ``the United States'' as a 
    potential owner or operator of a municipal separate storm sewer. This 
    addition was intended to address an omission from existing regulations 
    and to clarify that federal facilities are, in fact, covered by the 
    NPDES program for municipal storm water discharges when the federal 
    facility is like other regulated MS4s. EPA received a comment that this 
    change would cause federal facilities located in Phase 1 areas to be 
    considered Phase 1 dischargers due to the definition of medium and 
    large MS4s. All MS4s located in Phase 1 cities or counties are defined 
    as Phase 1 medium or large MS4s. EPA believes that all federal 
    facilities serve a population of under 100,000 and should be regulated 
    as small MS4s. Therefore, in Sec. 122.26(a)(16) of today's final rule, 
    EPA is adding federal facilities to the NPDES storm water discharge 
    control program by changing the proposed definition of small municipal 
    separate storm sewer system. Paragraph (i) of this section restates the 
    definition of municipal separate storm sewer with the addition of ``the 
    United States'' as a owner or operator of a small municipal separate 
    storm sewer. Paragraph (ii) repeats the proposed language that states 
    that a small MS4 is a municipal separate storm sewer that is not medium 
    or large.
        Most commenters agreed that federal facilities should be covered in 
    the same way as other similar MS4s. However, EPA received several 
    comments asking whether individual federal buildings such as post 
    offices or urban offices of the U.S. Park Service must apply for 
    coverage as regulated small MS4s. Most of these buildings have, at 
    most, a parking lot with runoff or a storm sewer that connects with a 
    municipality's MS4. In Sec. 122.26(a)(16)(iii), EPA clarifies that the 
    definition of small MS4 does not include individual buildings. These 
    buildings may have a municipal separate storm sewer but they do not 
    have a ``system'' of conveyances. The minimum measures for small MS4s 
    were written to apply to storm sewer ``systems'' providing storm water 
    drainage service to human populations and not to individual buildings. 
    This is true of municipal separate storm sewers from State buildings as 
    well as from federal buildings.
        There will likely be situations where the permitting authority must 
    decide if a federal or State complex should be regulated as a small 
    MS4. A federal complex of two or three buildings could be treated as a 
    single building and not be required to apply for coverage. In these 
    situations, permitting authorities will have to use their best judgment 
    as to the nature of the complex and its storm water conveyance system. 
    Permitting authorities should also consider whether the federal or 
    State complex cooperates with its municipality's efforts to implement 
    their storm water management program.
        Along with the questions about individual buildings, EPA received 
    many questions about how various provisions of the rule should be 
    interpreted for federal and State facilities. EPA acknowledges that 
    federal and State facilities are different from municipalities. EPA 
    believes, however, that the minimum measures are flexible enough that 
    they can be implemented by these facilities. As an example, DOD 
    commenters asked about how to interpret the term ``public'' for 
    military installations when implementing the public education measure. 
    EPA agrees with the suggested interpretation of ``public'' for DOD 
    facilities as ``the resident and employee population within the fence 
    line of the facility.''
        EPA also received many comments from State departments of 
    transportation (DOTs) that suggested the ways in which they are 
    different from municipalities and should therefore be regulated 
    differently. Storm water discharges from State DOTs in Phase 1 areas 
    should already be regulated under Phase I. The preamble to Phase 1 
    clearly states that ``all systems within a geographical area including 
    highways and flood control districts will be covered.'' Many permitting 
    authorities regulated State DOTs as co-permittees with the Phase 1 
    municipality in which the highway is located. State DOTs that are 
    already regulated under Phase I are not required to comply with Phase 
    II. State DOTs that are not already regulated have various options for 
    meeting the requirements of today's rule. These options are discussed 
    in Section II.H.3.c.iv below. Several DOTs commented that some of the 
    minimum measures are outside the scope of their mission or that they do 
    not have the legal authority required for implementation. EPA believes 
    that the flexibility of the minimum measures allows them to be 
    implemented by most MS4s, including DOTs. When a DOT does not have the 
    necessary legal authority, EPA encourages the DOT to coordinate their 
    storm water management efforts with the surrounding municipalities and 
    other State agencies. Under today's rule, DOTs can use any of the 
    options of Sec. 122.35 to share their storm water management 
    responsibilities. DOTs may also want to work with their permitting 
    authority to develop a State-wide DOT storm water permit.
        There are many storm water discharges from State DOTs and other 
    State MS4s located in Phase 1 areas that were not regulated under Phase 
    1. Today's rule adds many more State facilities as well as all federal 
    facilities located in urbanized areas. All of these State and federal 
    facilities that fit the definition of a small MS4 must be covered by a 
    storm water management program. The individual permitting authorities 
    must decide what type of permit is most applicable.
        The existing NPDES storm water program already regulates storm 
    water from federally or State-operated industrial sources. Federal or 
    State facilities that are currently regulated due to their industrial 
    discharges may already be implementing some of today's rule 
    requirements.
        EPA received comments that questioned the apparent inconsistency 
    between regulating a federal facility such as a hospital and not 
    regulating a similar private facility. Normally, this type of private 
    facility is regulated by the MS4. EPA believes that federal facilities 
    are subject to local water quality regulations, including storm water 
    requirements, by virtue of the waiver of sovereign immunity in CWA 
    section 313. However, there are special problems faced by MS4s in their 
    efforts to regulate federal facilities that have not been encountered 
    in regulating
    
    [[Page 68750]]
    
    similar private facilities. To ensure comprehensive coverage, today's 
    rule merely clarifies the need for permit coverage for these federal 
    facilities.
        i. Combined Sewer Systems (CSS). The definition of small MS4s does 
    not include combined sewer systems. A combined sewer system is a 
    wastewater collection system that conveys sanitary wastewater and storm 
    water through a single set of pipes to a publicly-owned treatment works 
    (POTW) for treatment before discharging to a receiving waterbody. 
    During wet weather events when the capacity of the combined sewer 
    system is exceeded, the system is designed to discharge prior to the 
    POTW treatment plant directly into a receiving waterbody. Such an 
    overflow is a combined sewer overflow or CSO. Combined sewer systems 
    are not subject to existing regulations for municipal storm water 
    discharges, nor will they be subject to today's regulations. EPA 
    addresses combined sewer systems and CSOs in the National Combined 
    Sewer Overflow (CSO) Control Policy issued on April 19, 1994 (59 FR 
    18688). The CSO Control Policy contains provisions for developing 
    appropriate, site-specific NPDES permit requirements for combined sewer 
    systems. CSO discharges are subject to limitations based on the best 
    available technology economically achievable for toxic pollutants and 
    based on the best conventional pollutant control technology for 
    conventional pollutants. MS4s are subject to a different technology 
    standard for all pollutants, specifically to reduce pollutants to the 
    maximum extent practicable.
        Some municipalities are served by both separate storm sewer systems 
    and combined sewer systems. If such a municipality is located within an 
    urbanized area, only the separate storm sewer systems within that 
    municipality is included in the NPDES storm water program and subject 
    to today's final rule. If the municipality is not located in an 
    urbanized area, then the NPDES permitting authority has discretion as 
    to whether the discharges from the separate storm sewer system is 
    subject to today's final rule. The NPDES permitting authority will use 
    the same process to designate discharges from portions of an MS4 for 
    permit coverage where the municipality is also served by a combined 
    sewer system.
        EPA recognizes that municipalities that have both combined and 
    separate storm sewer systems may wish to find ways to develop a unified 
    program to meet all wet weather water pollution control requirements 
    more efficiently. In the proposal to today's final rule, EPA sought 
    comment on ways to achieve such a unified program. Many municipalities 
    that are served by CSSs and MS4s commented that it is inequitable to 
    force them to comply with Phase II at this time because implementation 
    of the CSO Control Policy through their NPDES permits already imposes a 
    significant financial burden. They requested an extension of the 
    implementation time frame. They did not provide ideas on how to unify 
    the two programs. EPA encourages permitting authorities to work with 
    these municipalities as they develop and begin implementation of their 
    CSO and storm water management programs. If both sets of requirements 
    are carefully coordinated early, a cost-effective wet weather program 
    can be developed that will address both CSO and storm water 
    requirements.
        ii. Owners/Operators. Several commenters mentioned the difference 
    between the existing storm water application requirement for municipal 
    operators and the proposed municipal requirement for owners or 
    operators to apply. They felt that this inconsistency is confusing. The 
    preamble to the existing regulations makes numerous references to 
    owner/operator so there was no intent to make a clear distinction 
    between Phase I and Phase II. Section 122.21(b) states that when the 
    owner and operator are different, the operator must obtain the permit. 
    MS4s often have several operators. The owner may be responsible for one 
    part of the system and a regional authority may be responsible for 
    other aspects. EPA proposed the ``owner or operator'' language to 
    convey this dual responsibility. However, when the owner is responsible 
    for some part of a storm water management plan, it is also an operator.
        EPA has revised the regulation language to clarify that ``an 
    operator'' must apply for a permit. When responsibilities for the MS4 
    are shared, all operators must apply.
    c. Regulated Small MS4s
        In today's final rule, all small MS4s located in an urbanized area 
    are automatically designated as ``regulated'' small MS4s provided that 
    they were not previously designated into the existing storm water 
    program. Unlike medium and large MS4s under the existing storm water 
    regulations, not all small MS4s are designated under today's final 
    rule. Therefore, today's rule distinguishes between ``small'' MS4s and 
    ``regulated small'' MS4s.
        EPA's definition of ``regulated small MS4s'' in the proposal to 
    today's rule included mention of incorporated places and counties. 
    Along with the definition, EPA included Appendices 6 and 7 to assist in 
    the identification of areas that would probably require coverage as 
    ``automatically designated'' (Appendix 6) or ``potentially designated'' 
    (Appendix 7). The definition and the appendices raised many questions 
    about exactly who was required to comply with the proposed 
    requirements. Commenters raised issues about the definition of 
    ``incorporated place'' and the status of towns, townships, and other 
    places that are not considered incorporated by the Census Bureau. They 
    also asked about special districts, regional authorities, MS4s already 
    regulated, and other questions in order to clarify the rule's coverage.
        EPA has revised Sec. 122.32(a) to clarify that discharges are 
    regulated under today's rule if they are from a small MS4 that is in an 
    urbanized area and has not received a waiver or they are designated by 
    the permitting authority. Today's rule does not regulate the county, 
    city, or town. Today's rule regulates the MS4. Therefore, even though a 
    county may be listed in Appendix 6, if that county does not own or 
    operate the municipal storm sewer systems, the county does not have to 
    submit an application or develop a storm water management program. If 
    another entity does own or operate an MS4 within the county, for 
    example, a regional utility district, that other entity needs to submit 
    the application and develop the program.
        Some commenters suggested that EPA should change the rule language 
    to specifically allow regional authorities to be the permitted entity 
    and to allow small MS4s to apply as co-permittees. EPA believes that 
    the best way to clarify that regional authorities can be the primary 
    permitted entity is the change to Sec. 122.32(a) and the explanation 
    above. Because EPA assumes that today's regulation will be implemented 
    through general permits, MS4s will not be co-permittees under a general 
    permit in the same manner as under individual permits. EPA has added 
    Sec. 122.33(a)(4) and made a minor change to Sec. 122.35(a) to clarify 
    that small MS4s can work together to share the responsibilities of a 
    storm water management program. This is discussed further in Section 
    II.H.3.c.iv below.
        The proposed rule stated that when a county or Federal Indian 
    reservation is only partially included in an urbanized area, only MS4s 
    in the urbanized portion of the county or Federal Indian reservation 
    would be regulated. In the rare cases when an incorporated place is 
    only partially included in the urbanized area, the entire incorporated 
    place would be regulated. EPA received comments asking about towns and
    
    [[Page 68751]]
    
    townships, because they were not considered to be incorporated areas 
    according to the Census Bureau's definition. Would the whole town/
    township be covered or only the part of the town/township in the 
    urbanized area? States use many different types of systems in their 
    geographical divisions. Some towns are similar to incorporated cities 
    and others are large areas that are more similar to counties. Some 
    commenters thought that the urbanized area boundary was arbitrary, and 
    if part of a town or county was covered, it all should be covered. 
    Other commenters noted that some townships and counties encompass very 
    large areas of which only a small portion is urbanized. Due to the 
    great variety of situations, EPA has decided that for all geographical 
    entities, only MS4s in the urbanized area are automatically designated. 
    The population densities associated with the Census Bureau's 
    designation of urbanized areas provide the basis for designation of 
    these areas to protect water quality. This focused designation provides 
    for consistency and allows for flexibility on the part of the MS4 and 
    the permitting authority. In those situations where an incorporated 
    place or a town is not all in an ``urbanized area'', there is a good 
    possibility that it is served by more than one MS4. In those cases 
    where the area is served by the same MS4, it makes sense to develop a 
    storm water program for the whole area. Permitting authorities may also 
    decide to designate all MS4s within a county or township, if they 
    believe it is necessary to protect water quality.
        Most operators of MS4s will not need to independently determine the 
    status of coverage under today's rule. EPA has revised the proposed 
    Appendices 6 and 7 to include towns and townships. Therefore, these 
    appendices will alert most MS4s as to whether they are likely to be 
    covered under today's rule. However, each permitting authority must 
    make the decision as to who requires coverage. Most likely, an 
    illustrative list of the regulated areas will be published with the 
    general permit. If not, the operator can contact its permitting 
    authority or the Bureau of the Census to find out if their separate 
    storm sewer systems are within an urbanized area.
        i. Urbanized Area Description. Under the Bureau of the Census 
    definition of ``urbanized area,'' adopted by EPA for the purposes of 
    today's final rule, ``an urbanized area (UA) comprises a place and the 
    adjacent densely settled surrounding territory that together have a 
    minimum population of 50,000 people.'' The proposal to today's rule 
    provided the full definition and case studies to help explain the 
    census category of ``urbanized area.'' Appendix 2 is a simplified 
    urbanized area illustration to help demonstrate the concept of 
    urbanized areas in relation to today's final rule. The ``urbanized 
    area'' is the shaded area that includes within its boundaries 
    incorporated places, a portion of a Federal Indian reservation, 
    portions of two counties, an entire town, and portions of another town. 
    All small MS4s located in the shaded area are covered by the rule, 
    unless and until waived by the permitting authority. Any small MS4s 
    located outside of the shaded area are subject to potential designation 
    by the permitting authority.
        There are 405 urbanized areas in the United States that cover 2 
    percent of total U.S. land area and contain approximately 63 percent of 
    the nation's population (see Appendix 3 for a listing of urbanized 
    areas of the United States and Puerto Rico). These numbers include U.S. 
    Territories, although Puerto Rico is the only territory to have Census-
    designated urbanized areas. Urbanized areas constitute the largest and 
    most dense areas of settlement. The purpose of determining an 
    ``urbanized area'' is to delineate the boundaries of development and 
    map the actual built-up urban area. The Bureau of the Census 
    geographers liken it to flying over an urban area and drawing a line 
    around the boundary of the built-up area as seen from the air.
        Using data from the latest decennial census, the Census Bureau 
    applies the urbanized area definition nationwide (including U.S. Tribes 
    and Territories) and determines which places and counties are included 
    within each urbanized area. For each urbanized area, the Bureau 
    provides full listings of who is included, as well as detailed maps and 
    special CD-ROM files for use with computerized mapping systems (such as 
    GIS). Each State's data center receives a copy of the list, and some 
    maps, automatically. The States also have the CD-ROM files and a 
    variety of publications available to them for reference from the Bureau 
    of the Census. In addition, local or regional planning agencies may 
    have urbanized area files already. New listings for urbanized areas 
    based on the 2000 Census will be available by July/August 2001, but the 
    more comprehensive computer files will not be available until late 
    2001/early 2002.
        Additional designations based on subsequent census years will be 
    governed by the Bureau of the Census' definition of an urbanized area 
    in effect for that year. Based on historical trends, EPA expects that 
    any area determined by the Bureau of the Census to be included within 
    an urbanized area as of the 1990 Census will not later be excluded from 
    the urbanized area as of the 2000 Census. However, it is important to 
    note that even if this situation were to occur, for example, due to a 
    possible change in the Bureau of the Census' urbanized area definition, 
    a small MS4 that is automatically designated into the NPDES program for 
    storm water under an urbanized area calculation for any given Census 
    year will remain regulated regardless of the results of subsequent 
    urbanized area calculations.
        ii. Rationale for Using Urbanized Areas. EPA is using urbanized 
    areas to automatically designate regulated small MS4s on a nationwide 
    basis for several reasons: (1) studies and data show a high correlation 
    between degree of development/ urbanization and adverse impacts on 
    receiving waters due to storm water (U.S. EPA, 1983; Driver et al., 
    1985; Pitt, R.E. 1991. ``Biological Effects of Urban Runoff

    Prepared for the Sediment and Storm water Administration of the 
    Maryland Department of the Environment.; Klein, 1979), (2) the blanket 
    coverage within the urbanized area encourages the watershed approach 
    and addresses the problem of ``donut-holes,'' where unregulated areas 
    are surrounded by areas currently regulated (storm water discharges 
    from donut hole areas present a problem due to their contributing 
    uncontrolled adverse impacts on local waters, as well as by frustrating 
    the attainment of water quality goals of neighboring regulated 
    communities), (3) this approach targets present and future growth areas 
    as a preventative measure to help ensure water quality protection, and 
    (4) the determination of urbanized areas by the Bureau of the Census 
    allows operators of small MS4s to quickly determine whether they are 
    included in the NPDES storm water program as a regulated small MS4.
        Urbanized areas have experienced significant growth over the past 
    50 years. According to EPA calculations
    
    [[Page 68752]]
    
    based on Census data from 1980 to 1990, the national average rate of 
    growth in the United States during that 10-year period was more than 4 
    percent. For the same period, the average growth within urbanized areas 
    was 15.7 percent and the average for outside of urbanized areas was 
    just more than 1 percent. The new development occurring in these 
    growing areas can provide some of the best opportunities for 
    implementing cost-effective storm water management controls.
        EPA received many comments on the proposal to designate discharges 
    based on location within urbanized areas. EPA considered numerous other 
    approaches, several of which are discussed in the proposal to today's 
    final rule. Several commenters wanted designation to be based on proven 
    water quality problems rather than inclusion in an urbanized area. One 
    commenter proposed an approach based on the CWA 303(d) listing of 
    impaired waters and the wasteload allocation conducted under the TMDL 
    process. (See section II.L. on the section 303(d) and TMDL process). 
    The commenter's proposal would designate small MS4s on a case-by-case 
    basis, covering only those discharges where receiving streams are shown 
    to have water quality problems, particularly a failure to meet water 
    quality standards, including designated uses. The commenter further 
    described a non-NPDES approach where a State would require cost-
    effective measures based on a proportionate share under a waste load 
    allocation, equitably allocated among all pollutant contributors. These 
    waste load allocations would be developed with input from all 
    stakeholders, and remedial measures would be implemented in a phased 
    manner based on the probability of results and/or economic feasibility. 
    The States would then periodically reassess the receiving streams to 
    determine whether the remedial measures are working, and if not, 
    require additional control measures using the same procedure used to 
    establish the initial measures. What the commenter describes is almost 
    a TMDL.
        EPA considered a remedial approach based on water quality 
    impairment and rejected it for failure to prevent almost certain 
    degradation caused by urban storm water. EPA's main concern in opting 
    not to take a case-by-case approach to designation was that this 
    approach would not provide controls for storm water discharges in 
    receiving streams until after a site-specific demonstration of adverse 
    water quality impact. The commenter's suggestion would do nothing to 
    prevent pollution in waters that may be meeting water quality 
    standards, including supporting designated uses. The approach would 
    also rely on identifying storm water management programs following 
    comprehensive watershed plans and TMDL development. In most States, 
    water quality assessments have traditionally been conducted for 
    principal mainstream rivers and their major tributaries, not all 
    surface waters. The establishment of TMDLs nationwide will take many 
    years, and many States will conduct additional monitoring to determine 
    water quality conditions prior to establishing TMDLs. In addition, a 
    case-by-case approach would not address the problem of ``donut holes'' 
    within urbanized areas and a lack of consistency among similarly 
    situated municipal systems would remain commonplace. After careful 
    consideration of all comments, EPA still believes that the approach in 
    today's rule is the most appropriate to protect water quality. 
    Protection includes prevention as well as remediation.
    d. Municipal Designation by the Permitting Authority
        Today's final rule also allows NPDES permitting authorities to 
    designate MS4s that should be included in the storm water program as 
    regulated small MS4s but are not located within urbanized areas. The 
    final rule requires, at a minimum, that a set of designation criteria 
    be applied to all small MS4s within a jurisdiction that serves a 
    population of at least 10,000 and has a population density of at least 
    1,000. Appendix 7 to this preamble provides an illustrative list of 
    places that the Agency anticipates meet this criteria. In addition, any 
    small MS4 may be the subject of a petition to the NPDES permitting 
    authority for designation. See Section II.G, NPDES Permitting 
    Authority's Role for more details on the designation and petition 
    processes. EPA believes that the approach of combining nationwide and 
    local designation to determine municipal coverage balances the 
    potential for significant adverse impacts on water quality with local 
    watershed protection and planning efforts.
    e. Waiving the Requirements for Small MS4s
        Today's final rule includes some flexibility in the nationwide 
    coverage of all small MS4s located in urbanized areas by providing the 
    NPDES permitting authority with the discretion to waive the otherwise 
    applicable requirements of the smallest MS4s that are not causing the 
    impairment of a receiving water body. Qualifications for the waiver 
    vary depending on whether the MS4 serves a population under 1,000 or a 
    population between 1,000 and 10,000. Note that even if a small MS4 has 
    requirements waived, it can subsequently be brought back into the 
    program if circumstances change. See Section II.G, NPDES Permitting 
    Authority's Role, for more details on this process.
    3. Municipal Permit Requirements
    a. Overview
        i. Summary of Permitting Options. Today's rule outlines six minimum 
    control measures that constitute the framework for a storm water 
    discharge control program for regulated small MS4s that, when properly 
    implemented, will reduce pollutants to the maximum extent practicable 
    (MEP). These six minimum control measures are specified in 
    Sec. 122.34(b) and are discussed below in section ``II.H.3.b, Program 
    Requirements-Minimum Control Measures.'' All operators of regulated 
    small MS4s are required to obtain coverage under an NPDES permit, 
    unless the requirement is waived by the permitting authority in 
    accordance with today's rule. Implementation of Sec. 122.34(b) may be 
    required either through an individual permit or, if the State or EPA 
    makes one available to the facility, through a general permit. The 
    process for issuing and obtaining these permits is discussed below in 
    section ``II.H.3.c, Application Requirements.''
        As an alternative to implementing a program that complies with the 
    requirements of Sec. 122.34, today's rule provides operators of 
    regulated small MS4s with the option of applying for an individual 
    permit under Sec. 122.26(d). The permit application requirements in 
    Sec. 122.26 were originally drafted to apply to medium and large MS4s. 
    Although EPA believes that the requirements of Sec. 122.34 provide a 
    regulatory option that is appropriate for most small MS4s, the 
    operators of some small MS4s may prefer more individualized 
    requirements. This alternative permitting option for regulated small 
    MS4s that wish to develop their own program is discussed below in 
    section ``II.H.3.c.iii. Alternative Permit Option.'' The second 
    alternative permitting option for regulated small MS4s is to become co-
    permittees with a medium or large MS4 regulated under Sec. 122.26(d), 
    as discussed below in section ``II.H.3.c.v. Joint Permit Programs.''
        ii. Water Quality-Based Requirements. Any NPDES permit issued under 
    today's rule must, at a minimum, require the operator to develop, 
    implement, and
    
    [[Page 68753]]
    
    enforce a storm water management program designed to reduce the 
    discharge of pollutants from a regulated system to the MEP, to protect 
    water quality, and satisfy the appropriate water quality requirements 
    of the Clean Water Act (see MEP discussion in the following section). 
    Absent evidence to the contrary, EPA presumes that a small MS4 program 
    that implements the six minimum measures in today's rule does not 
    require more stringent limitations to meet water quality standards. 
    Proper implementation of the measures will significantly improve water 
    quality. As discussed further below, however, small MS4 permittees 
    should modify their programs if and when available information 
    indicates that water quality considerations warrant greater attention 
    or prescriptiveness in specific components of the municipal program. If 
    the program is inadequate to protect water quality, including water 
    quality standards, then the permit will need to be modified to include 
    any more stringent limitations necessary to protect water quality.
        Regardless of the basis for the development of the effluent 
    limitations (whether designed to implement the six minimum measures or 
    more stringent or prescriptive limitations to protect water quality), 
    EPA considers narrative effluent limitations requiring implementation 
    of BMPs to be the most appropriate form of effluent limitations for 
    MS4s. CWA section 402(p)(3)(b)(iii) expresses a preference for 
    narrative rather than numeric effluent limits, for example, by 
    reference to ``management practices, control techniques and system, 
    design and engineering methods, and such other provisions as the 
    Administrator or the State determines appropriate for the control of 
    such pollutants.'' 33 U.S.C. 1342(p)(3)(B)(iii). EPA determines that 
    pollutants from wet weather discharges are most appropriately 
    controlled through management measures rather than end-of-pipe numeric 
    effluent limitations. As explained in the Interim Permitting Policy for 
    Water Quality-Based Effluent Limitations in Storm Water Permits, issued 
    on August 1, 1996 [61 FR 43761 (November 26, 1996), EPA believes that 
    the currently available methodology for derivation of numeric water 
    quality-based effluent limitations is significantly complicated when 
    applied to wet weather discharges from MS4s (compared to continuous or 
    periodic batch discharges from most other types of discharge). Wet 
    weather discharges from MS4s introduce a high degree of variability in 
    the inputs to the models currently available for derivation of water 
    quality based effluent limitations, including assumptions about 
    instream and discharge flow rates, as well as effluent 
    characterization. In addition, EPA anticipates that determining 
    compliance with any such numeric limitations may be confounded by 
    practical limitations in sample collection.
        In the first two to three rounds of permit issuance, EPA envisions 
    that a BMP-based storm water management program that implements the six 
    minimum measures will be the extent of the NPDES permit requirements 
    for the large majority of regulated small MS4s. Because the six 
    measures represent a significant level of control if properly 
    implemented, EPA anticipates that a permit for a regulated small MS4 
    operator implementing BMPs to satisfy the six minimum control measures 
    will be sufficiently stringent to protect water quality, including 
    water quality standards, so that additional, more stringent and/or more 
    prescriptive water quality based effluent limitations will be 
    unnecessary.
        If a small MS4 operator implements the six minimum control measures 
    in Sec. 122.34(b) and the discharges are determined to cause or 
    contribute to non-attainment of an applicable water quality standard, 
    the operator needs to expand or better tailor its BMPs within the scope 
    of the six minimum control measures. EPA envisions that this process 
    will occur during the first two to three permit terms. After that 
    period, EPA will revisit today's regulations for the municipal separate 
    storm sewer program.
        If the permitting authority (rather than the regulated small MS4 
    operator) needs to impose additional or more specific measures to 
    protect water quality, then that action will most likely be the result 
    of an assessment based on a TMDL or equivalent analysis that determines 
    sources and allocations of pollutant(s) of concern. EPA believes that 
    the small MS4's additional requirements, if any, should be guided by 
    its equitable share based on a variety of considerations, such as cost 
    effectiveness, proportionate contribution of pollutants, and ability to 
    reasonably achieve wasteload reductions. Narrative effluent limitations 
    in the form of BMPs may still be the best means of achieving those 
    reductions.
        See Section II.L, Water Quality Issues, for further discussion of 
    this approach to permitting, consistent with EPA's interim permitting 
    guidance. Pursuant to CWA section 510, States implementing their own 
    NPDES programs may develop more stringent or more prescriptive 
    requirements than those in today's rule.
        EPA's interpretation of CWA section 402(p)(3)(B)(iii) was recently 
    reviewed by the Ninth Circuit in Defenders of Wildlife, et al v. 
    Browner, No. 98-71080 (September 15, 1999). The Court upheld the 
    Agency's action in issuing five MS4 permits that included water 
    quality-based effluent limitations. The Court did, however, disagree 
    with EPA's interpretation of the relationship between CWA sections 301 
    and 402(p). The Court reasoned that MS4s are not compelled by section 
    301(b)(1)(C) to meet all State water quality standards, but rather that 
    the Administrator or the State may rely on section 402(p)(3)(B)(iii) to 
    require such controls. Accordingly, the Defenders of Wildlife decision 
    is consistent with the Agency's 1996 ``Interim Permitting Policy for 
    Water Quality-Based Effluent Limitations in Storm Water Permits.''
        As noted, the 1996 Policy describes how permits would implement an 
    iterative process using BMPs, assessment, and refocused BMPs, leading 
    toward attainment of water quality standards. The ultimate goal of the 
    iteration would be for water bodies to support their designated uses. 
    EPA believes this iterative approach is consistent with and implements 
    section 301(b)(1)(C), notwithstanding the Ninth Circuit's 
    interpretation. As an alternative to basing these water quality-based 
    requirements on section 301(b)(1)(C), however, EPA also believes the 
    iterative approach toward attainment of water quality standards 
    represents a reasonable interpretation of CWA section 
    402(p)(3)(B)(iii). For this reason, today's rule specifies that the 
    ``compliance target'' for the design and implementation of municipal 
    storm water control programs is ``to reduce pollutants to the maximum 
    extent practicable (MEP), to protect water quality, and to satisfy the 
    appropriate water quality requirements of the CWA.'' The first 
    component, reductions to the MEP, would be realized through 
    implementation of the six minimum measures. The second component, to 
    protect water quality, reflects the overall design objective for 
    municipal programs based on CWA section 402(p)(6). The third component, 
    to implement other applicable water quality requirements of the CWA, 
    recognizes the Agency's specific determination under CWA section 
    402(p)(3)(B)(iii) of the need to achieve reasonable further progress 
    toward attainment of water quality standards according to the iterative 
    BMP process, as well as the determination that State or EPA officials 
    who establish TMDLs could allocate waste loads to
    
    [[Page 68754]]
    
    MS4s, as they would to other point sources.
        EPA does not presume that water quality will be protected if a 
    small MS4 elects not to implement all of the six minimum measures and 
    instead applies for alternative permit limits under Sec. 122.26(d). 
    Operators of such small MS4s that apply for alternative permit limits 
    under Sec. 122.26(d) must supply additional information through 
    individual permit applications so that the permit writer can determine 
    whether the proposed program reduces pollutants to the MEP and whether 
    any other provisions are appropriate to protect water quality and 
    satisfy the appropriate water quality requirements of the Clean Water 
    Act.
        iii. Maximum Extent Practicable. Maximum extent practicable (MEP) 
    is the statutory standard that establishes the level of pollutant 
    reductions that operators of regulated MS4s must achieve. The CWA 
    requires that NPDES permits for discharges from MS4s ``shall require 
    controls to reduce the discharge of pollutants to the maximum extent 
    practicable, including management practices, control techniques and 
    system, design and engineering methods.'' CWA Section 
    402(p)(3)(B)(iii). This section also calls for ``such other provisions 
    as the [EPA] Administrator or the State determines appropriate for the 
    control of such pollutants.'' EPA interprets this standard to apply to 
    all MS4s, including both existing regulated (large and medium) MS4s, as 
    well as the small MS4s regulated under today's rule.
        For regulated small MS4s under today's rule, authorization to 
    discharge may be under either a general permit or individual permit, 
    but EPA anticipates and expects that general permits will be the most 
    common permit mechanism. The general permit will explain the steps 
    necessary to obtain permit authorization. Compliance with the 
    conditions of the general permit and the series of steps associated 
    with identification and implementation of the minimum control measures 
    will satisfy the MEP standard. Implementation of the MEP standard under 
    today's rule will typically require the permittee to develop and 
    implement appropriate BMPs to satisfy each of the required six minimum 
    control measures.
        In issuing the general permit, the NPDES permitting authority will 
    establish requirements for each of the minimum control measures. 
    Permits typically will require small MS4 permittees to identify in 
    their NOI the BMPs to be performed and to develop the measurable goals 
    by which implementation of the BMPs can be assessed. Upon receipt of 
    the NOI from a small MS4 operator, the NPDES permitting authority will 
    have the opportunity to review the NOI to verify that the identified 
    BMPs and measurable goals are consistent with the requirement to reduce 
    pollutants under the MEP standard, to protect water quality, and to 
    satisfy the appropriate water quality requirements of the Clean Water 
    Act. If necessary, the NPDES permitting authority may ask the permittee 
    to revise their mix of BMPs, for example, to better reflect the MEP 
    pollution reduction requirement. Where the NPDES permit is not written 
    to implement the minimum control measures specified under 
    Sec. 122.34(b), for example in the case of an individual permit under 
    Sec. 122.33(b)(2)(ii), the MEP standard will be applied based on the 
    best professional judgment of the permit writer.
        Commenters argued that MEP is, as yet, an undefined term and that 
    EPA needs to further clarify the MEP standards by providing a 
    regulatory definition that includes recognition of cost considerations 
    and technical feasibility. Commenters argued that, without a 
    definition, the regulatory community is not adequately on notice 
    regarding the standard with which they need to comply. EPA disagrees 
    that affected MS4 permittees will lack notice of the applicable 
    standard. The framework for the small MS4 permits described in this 
    notice provides EPA's interpretation of the standard and how it should 
    be applied.
        EPA has intentionally not provided a precise definition of MEP to 
    allow maximum flexibility in MS4 permitting. MS4s need the flexibility 
    to optimize reductions in storm water pollutants on a location-by-
    location basis. EPA envisions that this evaluative process will 
    consider such factors as conditions of receiving waters, specific local 
    concerns, and other aspects included in a comprehensive watershed plan. 
    Other factors may include MS4 size, climate, implementation schedules, 
    current ability to finance the program, beneficial uses of receiving 
    water, hydrology, geology, and capacity to perform operation and 
    maintenance.
        The pollutant reductions that represent MEP may be different for 
    each small MS4, given the unique local hydrologic and geologic concerns 
    that may exist and the differing possible pollutant control strategies. 
    Therefore, each permittee will determine appropriate BMPs to satisfy 
    each of the six minimum control measures through an evaluative process. 
    Permit writers may evaluate small MS4 operator's proposed storm water 
    management controls to determine whether reduction of pollutants to the 
    MEP can be achieved with the identified BMPs.
        EPA envisions application of the MEP standard as an iterative 
    process. MEP should continually adapt to current conditions and BMP 
    effectiveness and should strive to attain water quality standards. 
    Successive iterations of the mix of BMPs and measurable goals will be 
    driven by the objective of assuring maintenance of water quality 
    standards. If, after implementing the six minimum control measures 
    there is still water quality impairment associated with discharges from 
    the MS4, after successive permit terms the permittee will need to 
    expand or better tailor its BMPs within the scope of the six minimum 
    control measures for each subsequent permit. EPA envisions that this 
    process may take two to three permit terms.
        One commenter observed that MEP is not static and that if the six 
    minimum control measures are not achieving the necessary water quality 
    improvements, then an MS4 should be expected to revise and, if 
    necessary, expand its program. This concept, it is argued, must be 
    clearly part of the definition of MEP and thus incorporated into the 
    binding and operative aspects of the rule. As is explained above, EPA 
    believes that it is. The iterative process described above is intended 
    to be sensitive to water quality concerns. EPA believes that today's 
    rule contains provisions to implement an approach that is consistent 
    with this comment.
    b. Program Requirements'Minimum Control Measures
        A regulated small MS4 operator must develop and implement a storm 
    water management program designed to reduce the discharge of pollutants 
    from their MS4 to protect water quality. The storm water management 
    program must include the following six minimum measures.
        i. Public Education and Outreach on Storm Water Impacts. Under 
    today's final rule, operators of small MS4s must implement a public 
    education program to distribute educational materials to the community 
    or conduct equivalent outreach activities about the impacts of storm 
    water discharges on water bodies and the steps to reduce storm water 
    pollution. The public education program should inform individuals and 
    households about the problem and the steps they can take to reduce or 
    prevent storm water pollution.
        EPA believes that as the public gains a greater understanding of 
    the storm water program, the MS4 is likely to gain
    
    [[Page 68755]]
    
    more support for the program (including funding initiatives). In 
    addition, compliance with the program will probably be greater if the 
    public understands the personal responsibilities expected of them. 
    Well-informed citizens can act as formal or informal educators to 
    further disseminate information and gather support for the program, 
    thus easing the burden on the municipalities to perform all educational 
    activities.
        MS4s are encouraged to enter into partnerships with their States in 
    fulfilling the public education requirement. It may be more cost-
    effective to utilize a State education program instead of numerous MS4s 
    developing their own programs. MS4 operators are also encouraged to 
    work with other organizations (e.g., environmental, nonprofit and 
    industry organizations) that might be able to assist in fulfilling this 
    requirement.
        The public education program should be tailored, using a mix of 
    locally appropriate strategies, to target specific audiences and 
    communities (particularly minority and disadvantaged communities). 
    Examples of strategies include distributing brochures or fact sheets, 
    sponsoring speaking engagements before community groups, providing 
    public service announcements, implementing educational programs 
    targeted at school age children, and conducting community-based 
    projects such as storm drain stenciling, and watershed and beach 
    cleanups. Operators of MS4s may use storm water educational information 
    provided by the State, Tribe, EPA, or environmental, public interest, 
    trade organizations, or other MS4s. Examples of successful public 
    education efforts concerning polluted runoff can be found in many State 
    nonpoint source pollution control programs under CWA section 319.
        The public education program should inform individuals and 
    households about steps they can take to reduce storm water pollution, 
    such as ensuring proper septic system maintenance, ensuring the use and 
    disposal of landscape and garden chemicals including fertilizers and 
    pesticides, protecting and restoring riparian vegetation, and properly 
    disposing of used motor oil or household hazardous wastes. 
    Additionally, the program could inform individuals and groups on how to 
    become involved in local stream and beach restoration activities as 
    well as activities coordinated by youth service and conservation corps 
    and other citizen groups. Finally, materials or outreach programs 
    should be directed toward targeted groups of commercial, industrial, 
    and institutional entities likely to have significant storm water 
    impacts. For example, MS4 operators should provide information to 
    restaurants on the impact of grease clogging storm drains and to auto 
    garages on the impacts of used oil discharges.
        EPA received comments from representatives of State DOTs and U.S. 
    Department of Defense (DOD) installations seeking exemption from the 
    public education requirement. While today's rule does not exempt DOTs 
    and military bases from the user education requirement, the Agency 
    believes the flexibility inherent in the Rule addresses many of the 
    concerns expressed by these commenters.
        Certain DOT representatives commented that if their agencies were 
    not exempt from the user education measure's requirements, they should 
    at least be allowed to count DOT employee education as an adequate 
    substitute. EPA supports the use of existing materials and programs, 
    granted such materials and programs meet the rule's requirement that 
    the MS4 user community (i.e., the public) is also educated concerning 
    the impacts of storm water discharges on water bodies and the steps to 
    reduce storm water pollution.
        Finally, certain DOD representatives requested that ``public,'' as 
    applied to their installations, be defined as the resident and employee 
    populations within the fence line of the facility. EPA agrees that the 
    education effort should be directed toward those individuals who 
    frequent the federally owned land (i.e., residents and individuals who 
    come there to work and use the MS4 facilities).
        EPA also received a number of comments from municipalities stating 
    that education would be more thorough and cost effective if 
    accomplished by EPA on the national level. EPA believes that a 
    collaborative State and local approach, in conjunction with significant 
    EPA technical support, will best meet the goal of targeting, and 
    reaching, specific local audiences. EPA technical support will include 
    a tool box which will contain fact sheets, guidance documents, an 
    information clearinghouse, and training and outreach efforts.
        Finally, EPA received comments expressing concern that the public 
    education program simply encourages the distribution of printed 
    material. EPA is sensitive to this concern. Upon evaluation, the Agency 
    made changes to the proposal's language for today's rule. The language 
    has been changed to reflect EPA's belief that a successful program is 
    one that includes a variety of strategies locally designed to reach 
    specific audiences.
        ii. Public Involvement/Participation. Public involvement is an 
    integral part of the small MS4 storm water program. Accordingly, 
    today's final rule requires that the municipal storm water management 
    program must comply with applicable State and local public notice 
    requirements. Section 122.34(b)(2) recommends a public participation 
    process with efforts to reach out and engage all economic and ethnic 
    groups. EPA believes there are two important reasons why the public 
    should be allowed and encouraged to provide valuable input and 
    assistance to the MS4's program.
        First, early and frequent public involvement can shorten 
    implementation schedules and broaden public support for a program. 
    Opportunities for members of the public to participate in program 
    development and implementation could include serving as citizen 
    representatives on a local storm water management panel, attending 
    public hearings, working as citizen volunteers to educate other 
    individuals about the program, assisting in program coordination with 
    other pre-existing programs, or participating in volunteer monitoring 
    efforts. Moreover, members of the public may be less likely to raise 
    legal challenges to a MS4's storm water program if they have been 
    involved in the decision making process and program development and, 
    therefore, internalize personal responsibility for the program 
    themselves.
        Second, public participation is likely to ensure a more successful 
    storm water program by providing valuable expertise and a conduit to 
    other programs and governments. This is particularly important if the 
    MS4's storm water program is to be implemented on a watershed basis. 
    Interested stakeholders may offer to volunteer in the implementation of 
    all aspects of the program, thus conserving limited municipal 
    resources.
        EPA recognizes that there are a number of challenges associated 
    with public involvement. One challenge is in engaging people in the 
    public meeting and program design process. Another challenge is 
    addressing conflicting viewpoints. Nevertheless, EPA strongly believes 
    that these challenges can be addressed by use of an aggressive and 
    inclusive program. Section II.K. provides further discussion on public 
    involvement.
        A number of municipalities sought clarification from EPA concerning 
    what the public participation program must
    
    [[Page 68756]]
    
    actually include. In response, the actual requirements are minimal, but 
    the Agency's recommendations are more comprehensive. The public 
    participation program must only comply with applicable State and local 
    public notice requirements. The remainder of the preamble, as well as 
    the Explanatory Note accompanying the regulatory text, provide guidance 
    to the MS4s concerning what elements a successful and inclusive program 
    should include. EPA will provide technical support as part of the tool 
    box (i.e., providing model public involvement programs, conducting 
    public workshops, etc.) to assist MS4 operators meet the intent of this 
    measure.
        Finally, the Agency encourages MS4s to seek public participation 
    prior to submitting an NOI. For example, public participation at this 
    stage will allow the MS4 to involve the public in developing the BMPs 
    and measurable goals for their NOI.
        iii. Illicit Discharge Detection and Elimination. Discharges from 
    small MS4s often include wastes and wastewater from non-storm water 
    ``illicit'' discharges. Illicit discharge is defined at 40 CFR 
    122.26(b)(2) as any discharge to a municipal separate storm sewer that 
    is not composed entirely of storm water, except discharges pursuant to 
    an NPDES permit and discharges resulting from fire fighting activities. 
    As detailed below, other sources of non-storm water, that would 
    otherwise be considered illicit discharges, do not need to be addressed 
    unless the operator of the MS4 identifies one or more of them as a 
    significant source of pollutants into the system. EPA's Nationwide 
    Urban Runoff Program (NURP) indicated that many storm water outfalls 
    still discharge during substantial dry periods. Pollutant levels in 
    these dry weather flows were shown to be high enough to significantly 
    degrade receiving water quality. Results from a 1987 study conducted in 
    Sacramento, California, revealed that slightly less than one-half of 
    the water discharged from a municipal separate storm sewer system was 
    not directly attributable to precipitation runoff (U.S. Environmental 
    Protection Agency, Office of Research and Development. 1993. 
    Investigation of Inappropriate Pollutant Entries Into Storm Drainage 
    Systems--A User's Guide. Washington, DC EPA 600/R-92/238.) A 
    significant portion of these dry weather flows results from illicit 
    and/or inappropriate discharges and connections to the municipal 
    separate storm sewer system. Illicit discharges enter the system 
    through either direct connections (e.g., wastewater piping either 
    mistakenly or deliberately connected to the storm drains) or indirect 
    connections (e.g., infiltration into the storm drain system or spills 
    collected by drain inlets).
        Under the existing NPDES program for storm water, permit 
    applications for large and medium MS4s are to include a program 
    description for effective prohibition against non-storm water 
    discharges into their storm sewers (see 40 CFR 122.26 (d)(1)(v)(B) and 
    (d)(1)(iv)(B)). Further, EPA believes that in implementing municipal 
    storm water management plans under these permits, large and medium MS4 
    operators generally found their illicit discharge detection and 
    elimination programs to be cost-effective. Properly implemented 
    programs also significantly improved water quality.
        In today's rule, any NPDES permit issued to an operator of a 
    regulated small MS4 must, at a minimum, require the operator to 
    develop, implement and enforce an illicit discharge detection and 
    elimination program. Inclusion of this measure for regulated small MS4s 
    is consistent with the ``effective prohibition'' requirement for large 
    and medium MS4s. Under today's rule, the NPDES permit will require the 
    operator of a regulated small MS4 to: (1) Develop (if not already 
    completed) a storm sewer system map showing the location of all 
    outfalls, and names and location of all waters of the United States 
    that receive discharges from those outfalls; (2) to the extent 
    allowable under State, Tribal, or local law, effectively prohibit 
    through ordinance, or other regulatory mechanism, illicit discharges 
    into the separate storm sewer system and implement appropriate 
    enforcement procedures and actions as needed; (3) develop and implement 
    a plan to detect and address illicit discharges, including illegal 
    dumping, to the system; and (4) inform public employees, businesses, 
    and the general public of hazards associated with illegal discharges 
    and improper disposal of waste.
        The illicit discharge and elimination program need only address the 
    following categories of non-storm water discharges if the operator of 
    the small MS4 identifies them as significant contributors of pollutants 
    to its small MS4: water line flushing, landscape irrigation, diverted 
    stream flows, rising ground waters, uncontaminated ground water 
    infiltration (as defined at 40 CFR 35.2005(20)), uncontaminated pumped 
    ground water, discharges from potable water sources, foundation drains, 
    air conditioning condensation, irrigation water, springs, water from 
    crawl space pumps, footing drains, lawn watering, individual 
    residential car washing, flows from riparian habitats and wetlands, 
    dechlorinated swimming pool discharges, and street wash water 
    (discharges or flows from fire fighting activities are excluded from 
    the definition of illicit discharge and only need to be addressed where 
    they are identified as significant sources of pollutants to waters of 
    the United States). If the operator of the MS4 identifies one or more 
    of these categories of sources to be a significant contributor of 
    pollutants to the system, it could require specific controls for that 
    category of discharge or prohibit the discharges completely.
        Several comments were received on the mapping requirements of the 
    proposal. Most comments said that more flexibility should be given to 
    the MS4s to determine their mapping needs, and that resources could be 
    better spent in addressing problems once the illicit discharges are 
    detected. EPA reviewed the mapping requirements in the proposed rule 
    and agrees that some of the information is not necessary in order to 
    begin an illicit discharge detection and elimination program. Today's 
    rule requires a map or set of maps that show the locations of all 
    outfalls and names and locations of receiving waters. Knowing the 
    locations of outfalls and receiving waters are necessary to be able to 
    conduct dry weather field screening for non-storm water flows and to 
    respond to illicit discharge reports from the public. EPA recommends 
    that the operator collect any existing information on outfall locations 
    (e.g., review city records, drainage maps, storm drain maps), and then 
    conduct field surveys to verify the locations. It will probably be 
    necessary to ``walk'' (i.e. wade small receiving waters or use a boat 
    for larger receiving waters) the streambanks and shorelines, and it may 
    take more than one trip to locate all outfalls. A coding system should 
    be used to mark and identify each outfall. MS4 operators have the 
    flexibility to determine the type (e.g. topographic, GIS, hand or 
    computer drafted) and size of maps which best meet their needs. The map 
    scale should be such that the outfalls can be accurately located. Once 
    an illicit discharge is detected at an outfall, it may be necessary to 
    map that portion of the storm sewer system leading to the outfall in 
    order to locate the source of the discharge.
        Several comments requested clarification of the requirement to 
    develop and implement a plan to detect and eliminate illicit 
    discharges. EPA recommends that plans include procedures for the 
    following: locating priority areas; tracing the source of an illicit 
    discharge; removing the source of the discharge; and program evaluation
    
    [[Page 68757]]
    
    and assessment. EPA recommends that MS4 operators identify priority 
    areas (i.e., problems areas) for more detailed screening of their 
    system based on higher likelihood of illicit connections (e.g., areas 
    with older sanitary sewer lines), or by conducting ambient sampling to 
    locate impacted reaches. Once priority areas are identified, EPA 
    recommends visually screening outfalls during dry weather and 
    conducting field tests, where flow is occurring, of selected chemical 
    parameters as indicators of the discharge source. EPA's manual for 
    investigation of inappropriate pollutant entries into the storm 
    drainage system (EPA, 1993) suggests the following parameter list: 
    specific conductivity, fluoride and/or hardness concentration, ammonia 
    and/or potassium concentration, surfactant and/or fluorescence 
    concentration, chlorine concentration, pH and other chemicals 
    indicative of industrial sources. The manual explains why each 
    parameter is a good indicator and how the information can be used to 
    determine the type of source flow. The Agency is not recommending that 
    fluoride and chlorine, generally used to locate potable water 
    discharges, be addressed under this program, therefore a short list of 
    parameters may include conductivity, ammonia, surfactant and pH. Some 
    MS4s have found it useful to measure for fecal coliform or E. coli in 
    their testing program. Observations of physical characteristics of the 
    discharge are also helpful such as flow rate, temperature, odor, color, 
    turbidity, floatable matter, deposits and stains, and vegetation.
        The implementation plan should also include procedures for tracing 
    the source of an illicit discharge. Once an illicit discharge is 
    detected and field tests provide source characteristics, the next step 
    is to determine the actual location of the source. Techniques for 
    tracing the discharge to its place of origin may include: following the 
    flow up the storm drainage system via observations and/or chemical 
    testing in manholes or in open channels; televising storm sewers; using 
    infrared and thermal photography; conducting smoke or dye tests.
        The implementation plan should also include procedures for removing 
    the source of the illicit discharge. The first step may be to notify 
    the property owner and specify a length of time for eliminating the 
    discharge. Additional notifications and escalating legal actions should 
    also be described in this part of the plan.
        Finally, the implementation plan should include procedures for 
    program evaluation and assessment. Procedures could include 
    documentation of actions taken to locate and eliminate illicit 
    discharges such as: number of outfalls screened, complaints received 
    and corrected, feet of storm sewers televised, numbers of discharges 
    and quantities of flow eliminated, number of dye or smoke tests 
    conducted. Appropriate records of such actions should be kept and 
    should be submitted as part of the annual reports for the first permit 
    term, as specified by the permitting authority (reports only need to be 
    submitted in years 2 and 4 in later permits). For more on reporting 
    requirements, see Sec. 122.34(g).
        EPA received comments regarding an MS4's legal authority beyond its 
    jurisdictional boundaries to inspect or take enforcement against 
    illicit discharges. EPA recognizes that illicit flows may originate in 
    one jurisdiction and cross into one or more jurisdictions before being 
    discharged at an outfall. In such instances, EPA expects the MS4 that 
    detects the illicit flow to trace it to the point where it leaves their 
    jurisdiction and notify the adjoining MS4 of the flow, and any other 
    physical or chemical information. The adjoining MS4 should then trace 
    it to the source or to the location where it enters their jurisdiction. 
    The process of notifying the adjoining MS4 should continue until the 
    source is located and eliminated. In addition, because any non-storm 
    water discharge to waters of the U.S. through an MS4 is subject to the 
    prohibition against unpermitted discharges pursuant to CWA section 301 
    (a), remedies are available under the federal enforcement provisions of 
    CWA sections 309 and 505.
        EPA requested and received comments regarding the prohibition and 
    enforcement provision for this minimum measure. Commenters specifically 
    questioned the proposal that the operator only has to implement the 
    appropriate prohibition and enforcement procedures ``to the extent 
    allowable under State or Tribal law.'' They raised concerns that by 
    qualifying prohibition and enforcement procedures in this manner, the 
    operator could altogether ignore this minimum measure where affirmative 
    legal authority did not exist. Comments suggested that EPA require 
    States to grant authority to those municipalities where it did not 
    exist. Other comments, however, stated that municipalities cannot 
    exercise legal authority not granted to them under State law, which 
    varies considerably from one State to another. EPA has no intention of 
    directing State legislatures on how to allocate authority and 
    responsibility under State law. As noted above, there is at least one 
    remedy (the federal CWA) to control non-storm water discharges through 
    MS4s. If State law prevents political subdivisions from controlling 
    discharges through storm sewers, EPA anticipates common sense will 
    prevail to provide those MS4 operators with the ability to meet the 
    requirements applicable for their discharges.
        One comment reinforced the importance of public information and 
    education to the success of this measure. EPA agrees and suggests that 
    MS4 operators consider a variety of ways to inform and educate the 
    public which could include storm drain stenciling; a program to 
    promote, publicize, and facilitate public reporting of illicit 
    connections or discharges; and distribution of visual and/or printed 
    outreach materials. Recycling and other public outreach programs could 
    be developed to address potential sources of illicit discharges, 
    including used motor oil, antifreeze, pesticides, herbicides, and 
    fertilizers.
        EPA received comments that State DOT's lack authority to implement 
    this measure. EPA believes that most DOTs can implement most parts of 
    this measure. If a DOT does not have the necessary legal authority to 
    implement any part of this measure, EPA encourages them to coordinate 
    their storm water management efforts with the surrounding MS4s and 
    other State agencies. Many DOTs that are regulated under Phase I of 
    this program are co-permittees with the local regulated MS4. Under 
    today's rule, DOTs can use any of the options of Sec. 122.35 to share 
    their storm water management responsibilities.
        EPA received comments requesting clarification of various terms 
    such as ``outfall'' and ``illicit discharge.'' One comment asked EPA to 
    reinforce the point that a ``ditch'' could be considered an outfall. 
    The term ``outfall'' is defined at 40 CFR 122.26(b)(9) as ``a point 
    source at the point where a municipal separate storm sewer discharges 
    to waters of the United States * * *''. The term municipal separate 
    storm sewer is defined at 40 CFR Sec. 122.26(b)(8) as ``a conveyance or 
    system of conveyances (including roads with drainage systems, municipal 
    streets, catch basins, curbs, gutters, ditches, man-made channels, or 
    storm drains) * * *''. Following the logic of these definitions, a 
    ``ditch'' may be part of the municipal separate storm sewer, and at the 
    point where the ditch discharges to waters of the United States, it 
    would be an outfall. As with any determination about jurisdictional 
    provisions of the CWA, however, final decisions require case specific 
    evaluations of fact.
    
    [[Page 68758]]
    
        One commenter specifically requested clarification on the 
    relationship between the term ``illicit discharge'' and non-storm water 
    discharges from fire fighting. The comment suggested that it would be 
    impractical to attempt to determine whether the flow from a specific 
    fire (i.e., during a fire) is a significant source of pollution. EPA 
    intends that MS4s will address all allowable non-storm water flows 
    categorically rather than individually. If an MS4 is concerned that 
    flows from fire fighting are, as a category, contributing substantial 
    amounts of pollutants to their system, they could develop a program to 
    address those flows prospectively. The program may include an analysis 
    of the flow from several sources, steps to minimize the pollutant 
    contribution, and a plan to work with the sources of the discharge to 
    minimize any adverse impact on water quality. During the development of 
    such a program, the MS4 may determine that only certain types of flows 
    within a particular category are a concern, for example, fire fighting 
    flows at industrial sites where large quantities of chemicals are 
    present. In this example, a review of existing procedures with the fire 
    department and/or hazardous materials team may reveal weaknesses or 
    strengths previously unknown to the MS4 operator.
        EPA received comments requesting modifications to the rule to 
    include on-site sewage disposal systems (i.e., septic systems) in the 
    scope of the illicit discharge program. On-site sewage disposal systems 
    that flow into storm drainage systems are within the definition of 
    illicit discharge as defined by the regulations. Where they are found 
    to be the source of an illicit discharge, they need to be eliminated 
    similar to any other illicit discharge source. Today's rule was not 
    modified to include discharges from on-site sewage disposal systems 
    specifically because those sources are already within the scope of the 
    existing definition of illicit discharge.
        iv. Construction Site Storm Water Runoff Control. Over a short 
    period of time, storm water runoff from construction site activity can 
    contribute more pollutants, including sediment, to a receiving stream 
    than had been deposited over several decades (see section I.B.3). Storm 
    water runoff from construction sites can include pollutants other than 
    sediment, such as phosphorus and nitrogen, pesticides, petroleum 
    derivatives, construction chemicals, and solid wastes that may become 
    mobilized when land surfaces are disturbed. Generally, properly 
    implemented and enforced construction site ordinances effectively 
    reduce these pollutants. In many areas, however, the effectiveness of 
    ordinances in reducing pollutants is limited due to inadequate 
    enforcement or incomplete compliance with such local ordinances by 
    construction site operators (Paterson, R.G. 1994. ``Construction 
    Practices: The Good, the Bad, and the Ugly.'' Watershed Protection 
    Techniques 1(2)).
        Today's rule requires operators of regulated small MS4s to develop, 
    implement, and enforce a pollutant control program to reduce pollutants 
    in any storm water runoff from construction activities that result in 
    land disturbance of 1 or more acres (see Sec. 122.34(b)(4)). 
    Construction activity on sites disturbing less than one acre must be 
    included in the program if the construction activity is part of a 
    larger common plan of development or sale that would disturb one acre 
    or more.
        The construction runoff control program of the regulated small MS4 
    must include an ordinance or other regulatory mechanism to require 
    erosion and sediment controls to the extent practicable and allowable 
    under State, Tribal or local law. The program also must include 
    sanctions to ensure compliance (for example, non-monetary penalties, 
    fines, bonding requirements, and/or permit denials for non-compliance). 
    The program must also include, at a minimum: requirements for 
    construction site operators to implement appropriate erosion and 
    sediment control BMPS, such as silt fences, temporary detention ponds 
    and diversions; procedures for site plan review by the small MS4 which 
    incorporate consideration of potential water quality impacts; 
    requirements to control other waste such as discarded building 
    materials, concrete truck washout, chemicals, litter, and sanitary 
    waste at the construction site that may adversely impact water quality; 
    procedures for receipt and consideration of information submitted by 
    the public to the MS4; and procedures for site inspection and 
    enforcement of control measures by the small MS4.
        Today's rule provides flexibility for regulated small MS4s by 
    allowing them to exclude from their construction pollutant control 
    program runoff from those construction sites for which the NPDES 
    permitting authority has waived NPDES storm water small construction 
    permit requirements. For example, if the NPDES permitting authority 
    waives permit coverage for storm water discharges from construction 
    sites less than 5 acres in areas where the rainfall erosivity factor is 
    less than 5, then the regulated small MS4 does not have to include 
    these sites in its storm water management program. Even if requirements 
    for a discharge from a given construction site are waived by the NPDES 
    permitting authority, however, the regulated small MS4 may still chose 
    to control those discharges under the MS4's construction pollutant 
    control program, particularly where such discharges may cause siltation 
    problems in storm sewers. See Section II.I.1.b for more information on 
    construction waivers by the permitting authority.
        Some commenters suggested that the proposed construction minimum 
    measure requirements went beyond the permit application requirements 
    concerning construction for medium and large MS4s. In response, EPA has 
    made changes to the proposed measure so that it more closely resembles 
    the MS4 permit application requirements in existing regulations. For 
    example, as described below, the Agency revised the proposed 
    requirements for ``pre-construction review of site management plans'' 
    to require ``procedures for site plan review.''
        One commenter expressed concerns that addressing runoff from 
    construction sites within urbanized areas (through the small MS4 
    program) differently from construction sites outside urbanized areas 
    (which will not be covered by the small MS4 program) will encourage 
    urban sprawl. Today's rule, together with the existing requirements, 
    requires all construction greater than or equal to 1 acre, unless 
    waived, to be covered by an NPDES permit whether it is located inside 
    or outside of an urbanized area (see Sec. 122.26(b)(15)). Today's rule 
    does not require small MS4s to control runoff from construction sites 
    more stringently or prescriptively than is required for construction 
    site runoff outside urbanized areas. Therefore, today's rule imposes no 
    substantively different onsite controls on runoff of storm water from 
    construction sites in urbanized areas than from construction sites 
    outside of urbanized areas.
        One commenter recommended that the small MS4 construction site 
    storm water runoff control program address all storm water runoff from 
    construction sites, not just the runoff into the MS4. The commenter 
    also believed that MS4s should provide clear, objective standards for 
    all construction sites. EPA agrees. Because today's rule only regulates 
    discharges from the MS4, the construction pollutant control measure 
    only requires small MS4 operators to control runoff into its system. As 
    a practical matter, however, EPA anticipates that MS4 operators will 
    find that regulation of all construction site
    
    [[Page 68759]]
    
    runoff, whether they runoff into the MS4 or not, will prove to be the 
    most simple and efficient program. The Agency may provide more specific 
    criteria for construction site BMPs in the forthcoming rule being 
    developed under CWA section 402(m). See section II.D.1 of today's rule.
        One commenter stated that there is no need for penalties at the 
    local level by the small MS4 because the CWA already imposes sufficient 
    penalties to ensure compliance. EPA disagrees and believes that 
    enforcement and compliance at the local level is both necessary and 
    preferable. Examples of sanctions, some not available under the CWA, 
    include non-monetary penalties, monetary fines, bonding requirements, 
    and denial of future or other local permits.
        One commenter recommended that EPA should not include the 
    requirement to control pollutants other than sediment from construction 
    sites in this measure. EPA disagrees with this comment. The requirement 
    is to control waste that ``may cause adverse impacts on water 
    quality.'' Such wastes may include discarded building materials, 
    concrete truck washout, chemicals, pesticides, herbicides, litter, and 
    sanitary waste. These wastes, when exposed to and mobilized by storm 
    water, can contribute to water quality impairment.
        The proposed rule required ``procedures for pre-construction review 
    of site management plans.'' EPA requested comment on expanding this 
    provision to require both review and approval of construction site 
    storm water plans. Many commenters expressed the concern that review 
    and approval of site plans is not only costly and time intensive, but 
    may unnecessarily delay construction projects and unduly burden staff 
    who administer the local program. In addition, some commenters 
    expressed confusion whether EPA proposed pre-construction review for 
    all site management plans or only higher priority sites. To address 
    these comments, and be consistent with the permit application 
    requirements for larger MS4s, EPA changed ``procedures for pre-
    construction review of site management plans'' to ``procedures for site 
    plan review.'' Today's rule requires the small MS4 to develop 
    procedures for site plan review so as to incorporate consideration of 
    adverse potential water quality impacts. Procedures should include 
    review of site erosion and sediment control plans, preferably before 
    construction activity begins on a site. The objective is for the small 
    MS4 operator and the construction site operator to address storm water 
    runoff from construction activity early in the project design process 
    so that potential consequences to the aquatic environment can be 
    assessed and adverse water quality impacts can be minimized or 
    eliminated.
        One commenter requested that EPA delete the requirement for 
    ``procedures for receipt and consideration of information submitted by 
    the public'' because it went beyond existing storm water requirements. 
    Another commenter stated that establishing a separate process to 
    respond to public inquiries on a project is a burden to small 
    communities, especially if the project has gone through an 
    environmental review. One commenter requested clarification of this 
    provision. EPA has retained this requirement in today's final rule to 
    require some formality in the process for addressing public inquiries 
    regarding storm water runoff from construction activities. EPA does not 
    intend that small MS4s develop a separate, burdensome process to 
    respond to every public inquiry. A small MS4 could, for example, simply 
    log public complaints on existing storm water runoff problems from 
    construction sites and pass that information on to local inspectors. 
    The inspectors could then investigate complaints based on the severity 
    of the violation and/or priority area.
        One commenter believed that the proposed requirement of ``regular 
    inspections during construction'' would require every construction 
    project to be inspected more than once by the small MS4 during the term 
    of a construction project. EPA has deleted the reference to ``regular 
    inspections.'' Instead, the small MS4 will be required to ``develop 
    procedures for site inspection and enforcement of control measures.'' 
    Procedures could include steps to identify priority sites for 
    inspection and enforcement based on the nature and extent of the 
    construction activity, topography, and the characteristics of soils and 
    receiving water quality.
        In order to avoid duplication of small MS4 construction 
    requirements with NPDES construction permit requirements, today's rule 
    adds Sec. 122.44(s) to recognize that the NPDES permitting authority 
    can incorporate qualifying State, Tribal, or local erosion and sediment 
    control requirements in NPDES permits for construction site discharges. 
    For example, a construction site operator who complies with MS4 
    construction pollutant control programs that are referenced in the 
    NPDES construction permit would satisfy the requirements of the NPDES 
    permit. See section II.I.1.d for more information on incorporating 
    qualifying programs by reference into NPDES construction permits. This 
    provision has no impact on, or direct relation to, the small MS4 
    operator's responsibilities under the construction site storm water 
    runoff control minimum measure. Conversely, under Sec. 122.35(b), the 
    permitting authority may recognize in the MS4's permit that another 
    governmental entity, or the permitting authority itself, is responsible 
    for implementing one or more of the minimum measures (including 
    construction site storm water runoff control), and not include this 
    measure in the small MS4's permit. In this case, the other governmental 
    entity's program must satisfy all of the requirements of the omitted 
    measure.
        v. Post-Construction Storm Water Management in New Development and 
    Redevelopment. The NURP study and more recent investigations indicate 
    that prior planning and designing for the minimization of pollutants in 
    storm water discharges is the most cost-effective approach to storm 
    water quality management. Reducing pollutant concentrations in storm 
    water after the discharge enters a storm sewer system is often more 
    expensive and less efficient than preventing or reducing pollutants at 
    the source. Increased human activity associated with development often 
    results in increased pollutant loading from storm water discharges. If 
    potential adverse water quality impacts are considered from the 
    beginning stages of a project, new development and redevelopment 
    provides more opportunities for water quality protection. For example, 
    minimization of impervious areas, maintenance or restoration of natural 
    infiltration, wetland protection, use of vegetated drainage ways, and 
    use of riparian buffers have been shown to reduce pollutant loadings in 
    storm water runoff from developed areas. EPA encourages operators of 
    regulated small MS4s to identify specific problem areas within their 
    jurisdictions and initiate innovative solutions and designs to focus 
    attention on those areas through local planning.
        In today's rule at Sec. 122.34(b)(5), NPDES permits issued to an 
    operator of a regulated small MS4 will require the operator to develop, 
    implement, and enforce a program to address storm water runoff from new 
    development and redevelopment projects that result in land disturbance 
    of greater than or equal to one acre, including projects less than one 
    acre that are part of a larger common plan of development or sale, that 
    discharge into the MS4. Specifically, the NPDES permit will require the 
    operator of a regulated small MS4 to: (1) Develop and implement
    
    [[Page 68760]]
    
    strategies which include a combination of structural and/or non-
    structural best management practices (BMPs) appropriate for the 
    community; (2) use an ordinance, or other regulatory mechanism to 
    address post-construction runoff from new development and redevelopment 
    projects to the extent allowable under State, Tribal or local law; (3) 
    ensure adequate long-term operation and maintenance of BMPs; and (4) 
    ensure that controls are in place that would minimize water quality 
    impacts. EPA intends the term ``redevelopment'' to refer to alterations 
    of a property that change the ``footprint'' of a site or building in 
    such a way that results in the disturbance of equal to or greater than 
    1 acre of land. The term is not intended to include such activities as 
    exterior remodeling, which would not be expected to cause adverse storm 
    water quality impacts and offer no new opportunity for storm water 
    controls.
        EPA received comments requesting guidance and clarification of the 
    rule requirements. The scope of the comments ranged from general 
    requests for more details on how MS4 operators should accomplish the 
    four requirements listed above, to specific requests for information 
    regarding transfer of ownership for structural controls, as well as 
    ongoing responsibility for operation and maintenance. By the term 
    ``combination'' of BMPs, EPA intends a combination of structural and/or 
    non-structural BMPs. For this requirement, the term ``combination'' is 
    meant to emphasize that multiple BMPs should be considered and adopted 
    for use in the community. A single BMP generally cannot significantly 
    reduce pollutant loads because pollutants come from many sources within 
    a community. The BMPs chosen should: (1) Be appropriate for the local 
    community; (2) minimize water quality impacts; and (3) attempt to 
    maintain pre-development runoff conditions. In choosing appropriate 
    BMPs, EPA encourages small MS4 operators to participate in locally-
    based watershed planning efforts which attempt to involve a diverse 
    group of stakeholders. Each new development and redevelopment project 
    should have a BMP component. If an approach is chosen that primarily 
    focuses on regional or non-structural BMPs, however, then the BMPs may 
    be located away from the actual development site (e.g., a regional 
    water quality pond).
        Non-structural BMPs are preventative actions that involve 
    management and source controls such as: (1) Policies and ordinances 
    that provide requirements and standards to direct growth to identified 
    areas, protect sensitive areas such as wetlands and riparian areas, 
    maintain and/or increase open space (including a dedicated funding 
    source for open space acquisition), provide buffers along sensitive 
    water bodies, minimize impervious surfaces, and minimize disturbance of 
    soils and vegetation; (2) policies or ordinances that encourage infill 
    development in higher density urban areas, and areas with existing 
    storm sewer infrastructure; (3) education programs for developers and 
    the public about project designs that minimize water quality impacts; 
    and (4) other measures such as minimization of the percentage of 
    impervious area after development, use of measures to minimize directly 
    connected impervious areas, and source control measures often thought 
    of as good housekeeping, preventive maintenance and spill prevention. 
    Detailed examples of non-structural BMPs follow.
        Preserving open space may help to protect water quality as well as 
    provide other benefits such as recharging groundwater supplies, 
    detaining storm water, supporting wildlife and providing recreational 
    opportunities. Although securing funding for open space acquisition may 
    be difficult, various funding mechanisms have been used. New Jersey 
    uses a portion of their State sales tax (voter approved for a ten year 
    period) as a stable source of funding to finance the preservation of 
    historic sites, open space and farmland. Colorado uses part of the 
    proceeds from the State lottery to acquire and manage open space. Some 
    local municipalities use a percentage of the local sales tax revenue to 
    pay for open space acquisition (e.g., Jefferson County, CO has had an 
    open space program in place since 1977 funded by a 0.50 percent sales 
    tax). Open space can be acquired in the form of: fee simple purchase; 
    easements; development rights; purchase and sellback or leaseback 
    arrangements; purchase options; private land trusts; impact fees; and 
    land dedication requirements. Generally, fee simple purchases provide 
    the highest level of development control and certainty of preservation, 
    whereas the other forms of acquisition may provide less control, though 
    they would also generally be less costly.
        Cluster development, while allowing housing densities comparable to 
    conventional zoning practice, concentrates housing units in a portion 
    of the total site area which provides for greater open space, 
    recreation, stream protection and storm water control. This type of 
    development, by reducing lot sizes, can protect sensitive areas and 
    result in less impervious surface, as well as reduce the cost for roads 
    and other infrastructure.
        Minimizing directly connected impervious areas (DCIAs) is a 
    drainage strategy that seeks to reduce paved areas and directs storm 
    water runoff to landscaped areas or to structural controls such as 
    grass swales or buffer strips. This strategy can slow the rate of 
    runoff, reduce runoff volumes, attenuate peak flows, and encourage 
    filtering and infiltration of storm water. It can be made an integral 
    part of drainage planning for any development (Urban Drainage and Flood 
    Control District, Denver, CO. 1992. Urban Storm Drainage Criteria 
    Manual, Volume 3--Best Management Practices). The Urban Drainage and 
    Flood Control District manual describes three levels for minimizing 
    DCIAs. At Level 1 all impervious surfaces are made to drain over grass-
    covered areas before reaching a storm water conveyance system. Level 2 
    adds to Level 1 and replaces street curb and gutter systems with low-
    velocity grass-lined swales and pervious street shoulders. In addition 
    to Levels 1 and 2, Level 3 over-sizes swales and configures driveway 
    and street crossing culverts to use grass-lined swales as elongated 
    detention basins.
        Structural BMPs include: (1) Storage practices such as wet ponds 
    and extended-detention outlet structures; (2) filtration practices such 
    as grassed swales, sand filters and filter strips; and (3) infiltration 
    practices such as infiltration basins and infiltration trenches.
        EPA recommends that small MS4 operators ensure the appropriate 
    implementation of the structural BMPs by considering some or all of the 
    following: (1) Pre-construction review of BMP designs; (2) inspections 
    during construction to verify BMPs are built as designed; (3) post-
    construction inspection and maintenance of BMPs; and (4) sanctions to 
    ensure compliance with design, construction or operation and 
    maintenance (O&M) requirements of the program.
        EPA cautions that certain infiltration systems such as dry wells, 
    bored wells or tile drainage fields may be subject to Underground 
    Injection Control (UIC) program requirements (see 40 CFR Part 144.12.). 
    To find out more about these requirements, contact your state UIC 
    Program, or call EPA's Safe Drinking Water Hotline at 1-800-426-4791.
        In order to meet the third post-construction requirement (ensuring 
    adequate long-term O&M of BMPs), EPA recommends that small MS4 
    operators evaluate various O&M management agreement options. The most 
    common options are agreements between the
    
    [[Page 68761]]
    
    MS4 operator and another party such as post-development landowners 
    (e.g., homeowners' associations, office park owners, other government 
    departments or entities), or regional authorities (e.g., flood control 
    districts, councils of government). These agreements typically require 
    the post-construction property owner to be responsible for the O&M and 
    may include conditions which: allow the MS4 operator to be reimbursed 
    for O&M performed by the MS4 operator that is the responsibility of the 
    property owner but is not performed; allow the MS4 operator to enter 
    the property for inspection purposes; and in some cases specify that 
    the property owner submit periodic reports.
        In providing the guidance above, EPA intends the requirements in 
    today's rule to be consistent with the permit application requirements 
    for large MS4s for post-construction controls for new development and 
    redevelopment. MS4 operators have significant flexibility both to 
    develop this measure as appropriate to address local concerns, and to 
    apply new control technologies as they become available. Storm water 
    pollution control technologies are constantly being improved. EPA 
    recommends that MS4s be responsive to these changes, developments or 
    improvements in control technologies. EPA will provide more detailed 
    guidance addressing the responsibility for long-term O&M of storm water 
    controls in guidance materials. The guidance will also provide 
    information on appropriate planning considerations, structural controls 
    and non-structural controls. EPA also intends to develop a broad menu 
    of BMPs as guidance to ensure flexibility to accommodate local 
    conditions.
        EPA received comments suggesting that requirements for new 
    development be treated separately from redevelopment in the rule. The 
    comment stressed that new development on raw land presents fewer 
    obstacles and more opportunities to incorporate elements for preventing 
    water quality impacts, whereas redevelopment projects are constrained 
    by space limitations and existing infrastructure. Another comment 
    suggested allowing waivers from the redevelopment requirements if the 
    redevelopment does not result in additional adverse water quality 
    impacts, and where BMPs are not technologically or economically 
    feasible. EPA recognizes that redevelopment projects may have more site 
    constraints which narrow the range of appropriate BMPs. Today's rule 
    provides small MS4 operators with the flexibility to develop 
    requirements that may be different for redevelopment projects, and may 
    also include allowances for alternate or off-site BMPs at certain 
    redevelopment projects. Non-structural BMPs may be the most appropriate 
    approach for smaller redevelopment projects.
        EPA received comments requesting clarification on what is meant by 
    ``pre-development'' conditions within the context of redevelopment. 
    Pre-development refers to runoff conditions that exist onsite 
    immediately before the planned development activities occur. Pre-
    development is not intended to be interpreted as that period before any 
    human-induced land disturbance activity has occurred.
        EPA received comments on the guidance language in the proposed rule 
    and preamble which suggest that implementation of this measure should 
    ``attempt to maintain pre-development runoff conditions'' and that 
    ``post-development conditions should not be different than pre-
    development conditions in a way that adversely affects water quality.'' 
    Many comments expressed concern that maintaining pre-development runoff 
    conditions is impossible and cost-prohibitive, and objected to any 
    reference to ``flow'' or increase in volume of runoff. Other comments 
    support the inclusion of this language in the final rule. Similar 
    references in today's rule relating to pre-development runoff 
    conditions are intended as recommendations to attempt to maintain pre-
    development runoff conditions. With these recommendations, EPA intends 
    to prevent water quality impacts resulting from increased discharges of 
    pollutants, which may result from increased volume of runoff. In many 
    cases, consideration of the increased flow rate, velocity and energy of 
    storm water discharges following development unavoidably must be taken 
    into consideration in order to reduce the discharge of pollutants, to 
    meet water quality standards and to prevent degradation of receiving 
    streams. EPA recommends that municipalities consider these factors when 
    developing their post-construction storm water management program.
        Some comments said that the quoted phrases in the paragraph above 
    are directives that imply federal land use control, which they argue is 
    beyond the authority of the CWA. EPA recognizes that land use planning 
    is within the authority of local governments.
        EPA disagrees, however, with the implication that today's rule 
    dictates any such land use decisions. The requirement for small MS4 
    operators to develop a program to address discharges resulting from new 
    development and redevelopment is essentially a pollution prevention 
    measure. The Rule provides the MS4 operator with flexibility to 
    determine the appropriate BMPs to address local water quality concerns. 
    EPA recognizes that these program goals may not be applied to every 
    site, and expects that MS4s will develop an appropriate combination of 
    BMPs to be applied on a site-by-site, regional or watershed basis.
        vi. Pollution Prevention/Good Housekeeping for Municipal 
    Operations. Under today's final rule, operators of MS4s must develop 
    and implement an operation and maintenance program (``program'') that 
    includes a training component and has the ultimate goal of preventing 
    or reducing storm water from municipal operations (in addition to those 
    that constitute storm water discharges associated with industrial 
    activity). This measure's emphasis on proper O&M of MS4s and employee 
    training, as opposed to requiring the MS4 to undertake major new 
    activities, is meant to ensure that municipal activities are performed 
    in the most efficient way to minimize contamination of storm water 
    discharges.
        The program must include government employee training that 
    addresses prevention measures pertaining to municipal operations such 
    as: parks, golf courses and open space maintenance; fleet maintenance; 
    new construction or land disturbance; building oversight; planning; and 
    storm water system maintenance. The program can use existing storm 
    water pollution prevention training materials provided by the State, 
    Tribe, EPA, or environmental, public interest, or trade organizations.
        EPA also encourages operators of MS4s to consider the following in 
    developing a program: (1) Implement maintenance activities, maintenance 
    schedules, and long-term inspection procedures for structural and non-
    structural storm water controls to reduce floatables and other 
    pollutants discharged from the separate storm sewers; (2) implement 
    controls for reducing or eliminating the discharge of pollutants from 
    streets, roads, highways, municipal parking lots, maintenance and 
    storage yards, waste transfer stations, fleet or maintenance shops with 
    outdoor storage areas, and salt/sand storage locations and snow 
    disposal areas operated by the MS4; (3) adopt procedures for the proper 
    disposal of waste removed from the separate storm sewer systems and 
    areas listed above in (2), including dredge
    
    [[Page 68762]]
    
    spoil, accumulated sediments, floatables, and other debris; and (4) 
    adopt procedures to ensure that new flood management projects are 
    assessed for impacts on water quality and existing projects are 
    assessed for incorporation of additional water quality protection 
    devices or practices. Ultimately, the effective performance of the 
    program measure depends on the proper maintenance of the BMPs, both 
    structural and non-structural. Without proper maintenance, BMP 
    performance declines significantly over time. Additionally, BMP neglect 
    may produce health and safety threats, such as structural failure 
    leading to flooding, undesirable animal and insect breeding, and odors. 
    Maintenance of structural BMPs could include: replacing upper levels of 
    gravel; dredging of detention ponds; and repairing of retention basin 
    outlet structure integrity. Maintenance of non-structural BMPs could 
    include updating educational materials periodically.
        EPA emphasizes that programs should identify and incorporate 
    existing storm water practices and training, as well as non-storm water 
    practices or programs that have storm water pollution prevention 
    benefits, as a means to avoid duplication of efforts and reduce overall 
    costs. EPA recommends that MS4s incorporate these new obligations into 
    their existing programs to the greatest extent feasible and urges 
    States to evaluate MS4 programs with programmatic efficiency in mind. 
    EPA designed this minimum control measure as a modified version of the 
    permit application requirements for medium and large MS4s described at 
    40 CFR 122.26(d)(2)(iv), in order to provide more flexibility for these 
    smaller MS4s. Today's requirements provide for a consistent approach to 
    control pollutants from O&M among medium, large, and regulated small 
    MS4s.
        By properly implementing a program, operators of MS4s serve as a 
    model for the rest of the regulated community. Furthermore, the 
    establishment of a long-term program could result in cost savings by 
    minimizing possible damage to the system from floatables and other 
    debris and, consequently, reducing the need for repairs.
        EPA received comments requesting clarification of what this measure 
    requires. Certain municipalities expressed concern that the measure has 
    the potential to impose significant costs associated with EPA's 
    requirement that operators of MS4s consider implementing controls for 
    reducing or eliminating the discharge of pollutants from streets, 
    roads, highways, municipal parking lots, and salt/sand storage 
    locations and snow disposal areas operated by the municipality. EPA 
    disagrees that a requirement to consider such controls will impose 
    considerable costs.
        One commenter objected to the preamble language from the proposal 
    suggesting that EPA does not expect the MS4 to undertake new activity. 
    While it remains the Agency's expectation that major new activity will 
    not be required, the MEP process should drive MS4s to incorporate the 
    measure's obligations into their existing programs to achieve the 
    pollutant reductions to the maximum extent practicable.
        Certain commenters requested a definition for ``municipal 
    operations.'' EPA has revised the language to more clearly define 
    municipal operations. Questions may remain concerning whether 
    discharges from specific municipal activities constitute discharges 
    associated with industrial activities (requiring NPDES permit 
    authorization according to the requirements for industrial storm water 
    that apply in that State) or from municipal operations (subject only to 
    the controls developed in the MS4 control program). Even though there 
    may be different substantive requirements that apply depending on the 
    source of the discharge, EPA has modified the deadlines for permit 
    coverage so that all the regulated municipally owned and operated 
    sources become subject to permit requirements on the same date. The 
    deadline is the same for permit coverage for this minimum measure as 
    for permit coverage for municipally owned/operated industrial sources.
    c. Application Requirements
        An NPDES permit that authorizes the discharge from a regulated 
    small MS4 may take the form of either an individual permit issued to 
    one or more facilities as co-permittees or a general permit that 
    applies to a group of MS4s. For reasons of administrative efficiency 
    and to reduce the paperwork burden on permittees, EPA expects that most 
    discharges from regulated small MS4s will be authorized under general 
    permits. These NPDES general permits will provide specific instructions 
    on how to obtain coverage, including application requirements. 
    Typically, such application requirements will be satisfied by the 
    submission of a Notice of Intent (NOI) to be covered by the general 
    permit. In this section, EPA explains the small MS4 operator's 
    application requirements for obtaining coverage under a NPDES permit 
    for storm water.
        i. Best Management Practices and Measurable Goals, Section 
    122.34(d) of today's rule requires the operator of a regulated small 
    MS4 that wishes to implement a program under Sec. 122.34 to identify 
    and submit to the NPDES permitting authority a list of the best 
    management practices (``BMPs'') that will be implemented for each 
    minimum control measure in their storm water management program. They 
    also must submit measurable goals for the development and 
    implementation of each BMP. The BMPs and the measurable goals must be 
    included either in an NOI to be covered under a general permit or in an 
    individual permit application.
        The operator's submission must identify, as appropriate, the months 
    and years in which the operator will undertake actions required to 
    implement each of the minimum control measures, including interim 
    milestones and the frequency of periodic actions. The Agency revised 
    references to ``starting and completing'' actions from the proposed 
    rule because many actions will be repetitive or ongoing. The submission 
    also must identify the person or persons responsible for implementing 
    or coordinating the small MS4 storm water program. See Sec. 122.34(d). 
    The submitted BMPs and measurable goals become enforceable according to 
    the terms of the permit. The first permit can allow the permittee up to 
    five years to fully implement the storm water management program.
        Several commenters opposed making the measurable goals enforceable 
    permit conditions. Some suggested that a permittee should be able to 
    change its goals so that BMPs that are not functioning as intended can 
    be replaced. EPA agrees that a permittee should be free to switch its 
    BMPs and corresponding goals to others that accomplish the minimum 
    measure or measures. The permittee is required to implement BMPs that 
    address the minimum measures in Sec. 122.34(b). If the permittee 
    determines that its original combination of BMPs are not adequate to 
    achieve the objectives of the municipal program, the MS4 should revise 
    its program to implement BMPs that are adequate and submit to the 
    permitting authority a revised list of BMPs and measurable goals. EPA 
    suggests that permits describe the process for revising BMPs and 
    measurable goals, such as whether the permittee should follow the same 
    procedures as were required for the submission of the original NOI and 
    whether the permitting authority's approval is necessary prior to the 
    permittee implementing the revised
    
    [[Page 68763]]
    
    BMPs. The permittee should indicate on its periodic report whether any 
    BMPs and measurable goals have been revised since the last periodic 
    report.
        Some commenters expressed concern that making the measurable goals 
    enforceable would encourage the development of easily attained goals 
    and, conversely, discourage the setting of ambitious goals. Others 
    noted that it is often difficult to determine the pollutant reduction 
    that can be achieved by BMPs until several years after implementation. 
    Much of the opposition to the enforceability of measurable goals 
    appears to have been based on a mistaken understanding that measurable 
    goals must consist of pollutant reduction targets to be achieved by the 
    corresponding BMPs.
        Today's rule requires the operator to submit either measurable 
    goals that serve as BMP design objectives or goals that quantify the 
    progress of implementation of the actions or performance of the 
    permittee's BMPs. At a minimum, the required measurable goals should 
    describe specific actions taken by the permittee to implement each BMP 
    and the frequency and the dates for such actions. Although the operator 
    may choose to do so, it is not required to submit goals that measure 
    whether a BMP or combination of BMPs is effective in achieving a 
    specific result in terms of storm water discharge quality. For example, 
    a measurable goal might involve a commitment to inspect a given number 
    of drainage areas of the collection system for illicit connections by a 
    certain date. The measurable goal need not commit to achieving a 
    specific amount of pollutant reduction through the elimination of 
    illicit connections. Other measurable goals could include the date by 
    which public education materials would be developed, a certain 
    percentage of the community participating in a clean-up campaign, the 
    development of a mechanism to address construction site runoff, and a 
    reduction in the percentage of imperviousness associated with new 
    development projects.
        To reduce the risk that permittees will develop inadequate BMPs, 
    EPA intends to develop a menu of BMPs to assist the operators of 
    regulated small MS4s with the development of municipal programs. States 
    may also develop a menu of BMPs. Today's rule provides that the 
    measurable goals that demonstrate compliance with the minimum control 
    measures in Secs. 122.34 (b)(3) through (b)(6) do not have to be met if 
    the State or EPA has not issued a menu of BMPs at the time the MS4 
    submits its NOI. Commenters pointed out that the proposed rule would 
    have made the measurable goals unenforceable if the menu of BMPs was 
    not available, but the proposal was silent as to the enforceability of 
    the implementation of BMPs. Today's rule clarifies that the operators 
    are not free to do nothing prior to the issuance of a menu of BMPs; 
    they still must make a good faith effort to implement the BMPs designed 
    to comply with each measure. See Sec. 122.34(d)(2). The operators would 
    not, however, be liable for failure to meet its measurable goals if a 
    menu of BMPs was not available at the time they submit their NOI.
        The proposed rule provision in Sec. 123.35 stated that the 
    ``[f]ailure to issue the menu of BMPs would not affect the legal status 
    of the general permit.'' This concept is included in the final rule in 
    Sec. 122.34(d)(2)'s clarification that the permittee still must comply 
    with other requirements of the general permit.
        Unlike the proposed rule, today's rule does not require that each 
    BMP in the menu developed by the State or EPA be regionally 
    appropriate, cost-effective and field-tested. Various commenters 
    criticized those criteria as unworkable, and one described them as 
    ``ripe for ambiguity and abuse.'' Other commenters feared that the 
    operators of regulated small MS4s would never be required to achieve 
    their goals until menus were developed that were cost-effective, field-
    tested and appropriate for every conceivable subregion.
        While some municipal commenters supported the requirement that a 
    menu of BMPs be made available that included BMPs that had been 
    determined to be regionally appropriate, field-tested and cost-
    effective, others raised concerns that they would be restricted to a 
    limited menu. Some commenters supported such a detailed menu because 
    they thought they would only be able to select BMPs that were on the 
    menu, while others thought that it was the permitting authority's 
    responsibility to develop BMPs narrowly tailored to their situation. In 
    response, EPA notes that the operators will not be restricted to 
    implementing only, or all of, the BMPs included on the menu. Since the 
    menu does not require permittees to implement the BMPs included on the 
    menu, it is also not necessary to apply the public notice and other 
    procedures that some commenters thought should be applied to the 
    development of the menu of BMPs.
        The purpose of the BMP menu is to provide guidance to assist the 
    operators of regulated small MS4s with the development and refinement 
    of their local program, not to limit their options. Permittees may 
    implement BMPs other than those on the menu unless a State restricts 
    its permittees to specific BMPs. To the extent possible, EPA will 
    develop a menu of BMPs that describes the appropriateness of BMPs to 
    specific regions, whether the BMPs have been field-tested, and their 
    approximate costs. The menu, however, is not intended to relieve 
    permittees of the need to implement BMPs that are appropriate for their 
    specific circumstances.
        If there are no known relevant BMPs for a specific circumstance, a 
    permittee has the option of developing and implementing pilot BMPs that 
    may be better suited to their circumstances. Where BMPs are 
    experimental, the permittee should consider committing to measurable 
    goals that address its schedule for implementing its selected BMPs 
    rather than goals of achieving specific pollutant reductions. If the 
    BMPs implemented by the permittee do not achieve the desired objective, 
    the permittee may be required to commit to different or revised BMPs.
        As stated in Sec. 123.35(g), EPA is committed to issuing a menu of 
    BMPs prior to the deadline for the issuance of permits. This menu would 
    serve as guidance for all operators of regulated small MS4s nationwide. 
    After developing the initial menu of BMPs, EPA intends to periodically 
    modify, update, and supplement the menu of BMPs based on the 
    assessments of the MS4 storm water program and research. States may 
    rely on EPA's menu of BMPs or issue their own. If States develop their 
    own menus, they would constitute additional guidance (or perhaps 
    requirements in some States) for the operators to follow. Several 
    commenters were confused by the proposed rule language that stated that 
    States must provide or issue a menu of BMPs and, if they fail to do so, 
    EPA ``may'' do so. Some read this language as not requiring either EPA 
    or the State to develop the menu. EPA had intended that it would 
    develop a menu and that States could either provide the EPA developed 
    menu or one developed by the State.
        EPA has dropped the proposed language that States ``must'' develop 
    the menu of BMPs. Some commenters thought that it was inappropriate to 
    require States to issue guidance. A menu of BMPs issued by either EPA 
    or a permittee's State will satisfy the condition in Sec. 122.34(d) 
    that a regulatory authority provide a menu of BMPs. A State could 
    require its permittees to follow its menu of BMPs provided that they 
    are adequate to implement Sec. 122.34(b).
        Several commenters raised concerns that operators of small MS4s 
    could be
    
    [[Page 68764]]
    
    required to submit their BMPs and measurable goals before EPA or the 
    State has issued a menu of BMPs. EPA has assumed primary responsibility 
    for developing a menu of BMPs to minimize the possibility of this 
    occurring. Should a general permit be issued before a menu of BMPs is 
    available, the permit writer would have the option of delaying the date 
    by which the identification of the BMPs and measurable goals must be 
    submitted to the permitting authority until some time after a menu of 
    BMPs is available.
        Several municipal commenters raised concerns that they would begin 
    to develop a program only to be later told by the permitting authority 
    or challenged in a citizen suit that their BMPs were inadequate. They 
    expressed a need for certainty regarding what their permit required. 
    Several commenters suggested that EPA require permitting authorities to 
    approve or disapprove the submitted BMPs and measurable goals. EPA 
    disagrees that formal approval or disapproval by the permitting 
    authority is needed.
        EPA acknowledges that the lack of a formal approval process does 
    place on the permittee some responsibility for designing and 
    determining the adequacy of its BMPs. Once the permittee has submitted 
    its BMPs to the permitting authority as part of its NOI, it must 
    implement them in order to achieve the corresponding measurable goals. 
    EPA does not believe that this results in the uncertainty to the extent 
    expressed by some commenters or unduly expose the permittee to the risk 
    of citizen suit. If the permit is very specific regarding what the 
    permittee must do, then the uncertainty is eliminated. If the permit is 
    less prescriptive, the permittee has greater latitude in determining 
    for itself what constitutes an adequate program. A citizen suit could 
    impose liability on the permittee only if the program that it develops 
    and implements clearly does not satisfy the requirements of the general 
    permit. EPA believes today's approach strikes a balance between the 
    competing goals of providing certainty as to what constitutes an 
    adequate program and providing flexibility to the permittees.
        Commenters were divided on whether five years was a reasonable and 
    expeditious schedule for a MS4 to implement its program. Some thought 
    that it was an appropriate amount of time to allow for the development 
    and implementation of adequate programs. One questioned whether the 
    permittee had to be implementing all of its program within that time, 
    and suggested that there may be cases where a permitting authority 
    would need flexibility to allow more time. One commenter suggested that 
    five years is too long and would amount to a relaxation of 
    implementation in their area. EPA believes it will take considerable 
    time to complete the tasks of initially developing a program, 
    commencing to implement it, and achieving results. EPA notes, however, 
    that full implementation of an appropriate program must occur as 
    expeditiously as possible, and not later than five years.
        EPA solicited comment on how an NOI form might best be formatted to 
    allow for measurable goal information (e.g., through the use of check 
    boxes or narrative descriptions) while taking into account the Agency's 
    intention to facilitate computer tracking. All commenters supported the 
    development of a checklist NOI, but most noted that there would need to 
    be room for additional information to cover unusual situations. One 
    noted that, while a summary of measurable goals might be reduced to one 
    sheet, attachments that more fully described the program and the 
    planned BMPs would be necessary. EPA agrees that in most cases a 
    ``checklist'' will not be able to capture the information on what BMPs 
    a permittee intends to implement and its measurable goals for their 
    implementation. EPA will continue to consider whether to develop a 
    model NOI form and make it available for permitting authorities that 
    choose to use it. What will be required on an MS4's NOI, however, is 
    more extensive than what is usually required on an NOI, so a ``form'' 
    NOI for MS4s may be impractical.
        ii. Individual Permit Application for a Sec. 122.34(b) program. In 
    some cases, an operator of a regulated small MS4s may seek coverage 
    under an individual NPDES permit, either because it chooses to do so or 
    because the NPDES permitting authority has not made the general permit 
    option available to that source. For small MS4s that are to implement a 
    Sec. 122.34(b) program in today's rule, EPA is promulgating simplified 
    individual permit application requirements at Sec. 122.33(b)(2)(i). 
    Under the simplified individual permit application requirements, the 
    operator submits an application to the NPDES permitting authority that 
    includes the information required under Sec. 122.21(f) and an estimate 
    of square mileage served by the small MS4. They are also required to 
    supply the BMP and measurable goal information required under 
    Sec. 122.34(d). Consistent with CWA section 308 and analogous State 
    law, the permitting authority could request any additional information 
    to gain a better understanding of the system and the areas draining 
    into the system.
        Commenters suggested that the requirements of Sec. 122.21(f) are 
    not necessarily applicable to a small MS4. One suggested that it was 
    not appropriate to require the following information: a description of 
    the activities conducted by the applicant which require it to obtain an 
    NPDES permit; the name, mailing address, and location of the facility; 
    and up to four Standard Industrial Classification (``SIC'') codes which 
    best reflect the principal products or services provided by the 
    facility. In response, EPA notes that the requirements in 
    Sec. 122.21(f) are generic application requirements applicable to NPDES 
    applicants. With the exception of the SIC code requirement, EPA 
    believes that they are applicable to MS4s. In the SIC code portion of 
    the standard application, the applicant may simply put ``not 
    applicable.''
        One commenter asked that EPA clarify whether Sec. 122.21(f)(5)'s 
    requirement to indicate ``whether the facility is located on Indian 
    lands,'' referred to tribal lands, Indian country, or Indian 
    reservations. For some local governments this is a complex issue with 
    no easy ``yes'' or ``no'' answer. See the discussion in the Section 
    II.F in the proposal to today's rule regarding what tribal lands are 
    subject to the federal trust responsibility for purposes of the NPDES 
    program.
        One commenter suggested that the application should not have to 
    list the permits and approvals required under Sec. 122.21(f)(6). EPA 
    notes that the applicant must only list the environmental permits that 
    the applicant has received that cover the small MS4. The applicant is 
    not required to list permits for other operations conducted by the 
    small MS4 operator (e.g., for an operation of an airport or landfill). 
    Again, in most cases the applicant could respond ``not applicable'' to 
    this portion of the application.
        One commenter suggested that the topographic map requirement of 
    Sec. 122.21(f)(7) was completely different from, and significantly more 
    onerous than, the mapping requirement outlined in the proposed rule at 
    Sec. 122.34(b)(3)(i). EPA agrees and has modified the final rule to 
    clarify that a map that satisfies the requirements of 
    Sec. 122.34(b)(3)(i) also satisfies the map requirements for MS4 
    applicants seeking individual permits under Sec. 122.33(b)(2)(i).
        EPA is adding a new paragraph to Sec. 122.44(k) to clarify that 
    requirements to implement BMPs developed pursuant to CWA 402(p) are 
    appropriate permit
    
    [[Page 68765]]
    
    conditions. While such conditions could be included under the existing 
    provision in Sec. 122.44(k)(3) for ``practices reasonably necessary to 
    achieve effluent limitations and standards or to carry out the purposes 
    and intent of the CWA,'' EPA believes it is clearer to specifically 
    list in Sec. 122.44(k) BMPs that implement storm water programs in 
    light of the frequency with which they are used as effluent 
    limitations.
        iii. Alternative Permit Options/Tenth Amendment. As an alternative 
    to implementing a program that addresses each of the six minimum 
    measures according to the requirements of Sec. 122.34(b), today's rule 
    provides the operators of regulated small MS4s with the option of 
    applying for an individual permit under existing Sec. 122.26(d). See 
    Sec. 122.33(b)(2)(ii). If a system operator does not want to be held 
    accountable for implementation of each of the minimum measures, an 
    individual permit option under Sec. 122.33(b)(2)(ii) remains available. 
    (As explained in the next section of this preamble, Sec. 122.35(b) also 
    provides an opportunity for relief from permit obligations for some of 
    the minimum measures, but that relief exists within the framework of 
    the minimum measures.)
        EPA originally drafted the individual permit application 
    requirements in Sec. 122.26(d) to apply to medium and large MS4s. 
    Today's rule abbreviates the individual permit application requirements 
    for small MS4s. Although EPA believes that the storm water management 
    program requirements of Sec. 122.34, including the minimum measures, 
    provide the most appropriate means to control pollutants from most 
    small MS4s, the Agency does recognize that the operators of some small 
    MS4s may prefer more individualized permit requirements. Among other 
    possible reasons, an operator may seek to avoid having to ``regulate'' 
    third parties discharging into the separate storm sewer system. 
    Alternatively, an operator may determine that structural controls, such 
    as constructed wetlands, are more appropriate or effective to address 
    the discharges that would otherwise be addressed under the construction 
    and/or development/redevelopment measures.
        Some MS4s commenters alleged that an absolute requirement to 
    implement the minimum measures violates the Tenth Amendment to the U.S. 
    Constitution. While EPA disagrees that requiring MS4s to implement the 
    minimum measures would violate the Constitution, today's rule does 
    provide small MS4s with the option of developing more individualized 
    measures to reduce the pollutants and pollution associated with urban 
    storm water that will be regulated under today's rule.
        Some commenters specifically objected that Sec. 122.34's minimum 
    measures for small MS4s violate the Tenth Amendment insofar as they 
    require the operators of MS4s to regulate third parties. The minimum 
    measures include requirements for small MS4 operators to prohibit 
    certain non-storm water discharges, control storm water discharges from 
    construction greater than one acre, and take other actions to control 
    third party sources of storm water discharges into their MS4s. 
    Commenters also argued that it was inappropriate for EPA to require 
    local governments to enact ordinances that will consume local revenues 
    and put local governments in the position of bearing the political 
    responsibility for implementing the program. One commenter argued that 
    EPA was prohibited from conditioning the issuance of an NPDES permit 
    upon the small MS4 operators waiving their constitutional right to be 
    free from such requirements to regulate third parties. The Agency 
    replies to each comment in turn.
        Because the rule does rely on local governments--who operate 
    municipal separate storm sewer systems--to regulate discharges from 
    third parties into storm sewers, EPA acknowledges that the rule 
    implicates the Tenth Amendment and constitutional principles of 
    federalism. EPA disagrees, however, that today's rule is inconsistent 
    with federalism principles. [As political subdivisions of States, 
    municipalities enjoy the same protections as States under the Tenth 
    Amendment.]
        The Supreme Court has interpreted the Tenth Amendment to preclude 
    federal actions that compel States or their political subdivisions to 
    enact or administer a federal regulatory program. See New York v. 
    United States, 505 U.S. 144 (1992); Printz v. United States, 117 S.Ct. 
    2365 (1997). The Printz case, however, did acknowledge that the 
    restriction does not apply when federal requirements of general 
    applicability--requirements that regulate all parties engaging in a 
    particular activity--do not excessively interfere with the functioning 
    of State governments when those requirements are applied to States (or 
    their political subdivisions). See Printz, 117 S.Ct. at 2383.
        Today's rule imposes a federal requirement of general 
    applicability, namely, the requirement to obtain and comply with an 
    NPDES permit, on municipalities that operate a municipal separate storm 
    sewer system. By virtue of this rule, the permit will require the 
    municipality/storm sewer operator to develop a storm water control 
    program. The rule specifies the components of the control program, 
    which are primarily ``management'-type controls, for example, municipal 
    regulation of third party storm water discharges associated with 
    construction, as well as development and redevelopment, when those 
    discharges would enter the municipal system.
    
        Unlike the circumstances reviewed in the New York and Printz cases, 
    today's rule merely applies a generally applicable requirement (the CWA 
    permit requirement) to municipal point sources. The CWA establishes a 
    generally applicable requirement to obtain an NPDES permit to authorize 
    point source discharge to waters of the United States. Because 
    municipalities own and operate separate storm sewers, including storm 
    sewers into which third parties may discharge pollutants, NPDES permits 
    may require municipalities to control the discharge of pollutants into 
    the storm sewers in the first instance. Because NPDES permits can 
    impose end-of-pipe numeric effluent limits, narrative effluent limits 
    in the form of ``management'' program requirements are also within the 
    scope of Clean Water Act authority. As noted above, however, EPA 
    believes that such narrative limitations are the most appropriate form 
    of effluent limitation for these types of permits. For municipal 
    separate storm sewer permits, CWA section 402(p)(3)(B)(iii) 
    specifically authorizes ``controls to reduce pollutants to the maximum 
    extent practicable, including management practices, control techniques 
    and system, design and engineering methods, and such other provisions 
    as the Administrator or the State determines appropriate for the 
    control of such pollutants.''
        The Agency did not design the minimum measures in Sec. 122.34 to 
    ``commandeer'' state regulatory mechanisms, but rather to reduce 
    pollutant discharges from small MS4s. The permit requirement in CWA 
    section 402 is a requirement of general applicability. The operator of 
    a small MS4 that does not prohibit and/or control discharges into its 
    system essentially accepts ``title'' for those discharges. At a 
    minimum, by providing free and open access to the MS4s that convey 
    discharges to the waters of the United States, the municipal storm 
    sewer system enables water quality impairment by third parties. Section 
    122.34 requires the operator of a regulated small MS4 to control a 
    third
    
    [[Page 68766]]
    
    party only to the extent that the MS4 collection system receives 
    pollutants from that third party and discharges it to the waters of the 
    United States. The operators of regulated small MS4s cannot passively 
    receive and discharge pollutants from third parties. The Agency 
    concedes that administration of a municipal program will consume 
    limited local revenues for implementation; but those consequences stem 
    from the municipal operator's identity as a permitted sewer system 
    operator. The Tenth Amendment does not create a blanket municipal 
    immunity from generally applicable requirements. Development of a 
    program based on the minimum measures and implementation of that 
    program should not ``excessively interfere'' with the functioning of 
    municipal government, especially given the ``practicability'' threshold 
    under CWA section 402(p)(3)(B)(iii).
        As noted above, today's rule also allows regulated small MS4s to 
    opt out of the minimum measures approach. The individual permit option 
    provides for greater flexibility in program implementation and also 
    responds to the comment about requiring a municipal permit applicant's 
    waiver of any arguable constitutional rights. The individual permit 
    option responds to questions about the rule's alleged 
    unconstitutionality by more specifically focusing on the pollutants 
    discharged from municipal point sources. Today's rule gives operators 
    of MS4s the option to seek an individual permit that varies from the 
    minimum measures/management approach that is otherwise specified in 
    today's rule. Even if the minimum measures approach was 
    constitutionally suspect, a requirement that standing alone would 
    violate constitutional principles of federalism does not raise concerns 
    if the entity subject to the requirement may opt for an alternative 
    action that does not raise a federalism issue.
        For municipal system operators who seek to avoid third party 
    regulation according to all or some of the minimum measures, 
    Sec. 122.26(d) requires the operator to submit a narrative description 
    of its storm water sewer system and any existing storm water control 
    program, as well as the monitoring data to enable the permit writer to 
    develop appropriate permit conditions. The permit writer can then 
    develop permit conditions and limitations that vary from the six 
    minimum measures prescribed in today's rule. The information will 
    enable the permit writer to develop an NPDES permit that will result in 
    pollutant reduction to the maximum extent practicable. See NRDC v. EPA, 
    966 F.2d at 1308, n17. If determined appropriate under CWA section 
    402(p)(3)(B)(iii), for example BMPs to meet water quality standards, 
    the permit could also incorporate any more stringent or prescriptive 
    effluent limits based on the individual permit application information.
        For small MS4 operators seeking an individual permit, both Part 1 
    and Part 2 of the application requirements in Sec. 122.26(d)(1) and (2) 
    are required to be submitted within 3 years and 90 days of the date of 
    publication of this Federal Register notice. Some of the information 
    required in Part 1 will necessarily have to be developed by the permit 
    applicant prior to the development of Part 2 of the application. The 
    permit applicant should coordinate with its permitting authority 
    regarding the timing of review of the information.
        The operators of regulated small MS4s that apply under 
    Sec. 122.26(d) may apply to implement certain of the Sec. 122.34(b) 
    minimum control measures, and thereby focus the necessary evaluation 
    for additional limitations on alternative controls to the 
    Sec. 122.34(b) measures that the small MS4 will not implement. The 
    permit writer may determine ``equivalency'' for some or all of the 
    minimum measures by developing a rough estimate of the pollutant 
    reduction that would be achieved if the MS4 implemented the Sec. 122.34 
    minimum measure and to incorporate that pollutant reduction estimate in 
    the small MS4's individual permit as an effluent limitation. The Agency 
    recognizes that, based on current information, any such estimates will 
    probably have a wide range. Anticipation of this wide range is one of 
    the reasons EPA believes MS4 operators need flexibility in determining 
    the mix of BMPs (under the minimum measures) to achieve water quality 
    objectives. Therefore, for example, if a system operator seeks to 
    employ an alternative that involves structural controls, wide ranges 
    will probably be associated with gross pollutant reduction estimates. 
    Permit writers will undoubtedly develop other ways to ensure that 
    permit limits ensure reduction of pollutants to the maximum extent 
    practicable.
        Small MS4 operators that pursue this individual permit option do 
    not need to submit details about their future program requirements 
    (e.g., the MS4's future plans to obtain legal authority required by 
    Secs. 122.26(d)(1)(ii) and (d)(2)). A small MS4 operator might elect to 
    supply such information if it intends for the permit writer to take 
    those plans into account when developing the small MS4's permit 
    conditions.
        Several operators of small MS4s commented that they currently 
    lacked the authority they would need to implement one or more of the 
    minimum measures in Sec. 122.34(b). Today's rule recognizes that the 
    operators of some small MS4s might not have the authority under State 
    law to implement one or more of the measures using, for example, an 
    ordinance or other regulatory mechanism. To address these situations, 
    each minimum measure in Sec. 122.34(b) that would require the small MS4 
    operator to develop an ordinance or other regulatory mechanism states 
    that the operator is only required to implement that requirement to 
    ``the extent allowable under State, Tribal or local law.'' See 
    Sec. 122.34(b)(3)(ii) (illicit discharge elimination), 
    Sec. 122.34(b)(4)(ii) (construction runoff control) and 
    Sec. 122.34(b)(5)(ii) (post-construction storm water management). This 
    regulatory language does not mean that a operator of a small MS4 with 
    ordinance making authority can simply fail to pass an ordinance 
    necessary for a Sec. 122.34(b) program. The reference to ``the extent 
    allowable under * * * local law'' refers to the local laws of other 
    political subdivisions to which the MS4 operator is subject. Rather, a 
    small MS4 operator that seeks to implement a program under section 
    Sec. 122.34(b) may omit a requirement to develop an ordinance or other 
    regulatory mechanism only to the extent its municipal charter, State 
    constitution or other legal authority prevents the operator from 
    exercising the necessary authority. Where the operator cannot obtain 
    the authority to implement any activity that is only required to ``the 
    extent allowable under State, Tribal or local law,'' the operator may 
    satisfy today's rule by administering the remaining Sec. 122.34(b) 
    requirements.
        Finally, although today's rule provides operators of small MS4s 
    with an option of applying for a permit under Sec. 122.26(d), States 
    authorized to administer the NPDES program are not required to provide 
    this option. NPDES-authorized States could require all regulated small 
    MS4s to be permitted under the minimum measures management approach in 
    Sec. 122.34 as a matter of State law. Such an approach would be deemed 
    to be equally or more stringent than what is required by today's rule. 
    See 40 CFR 123.2(i). The federalism concerns discussed above do not 
    apply to requirements imposed by a State on its political subdivisions.
        iv. Satisfaction of Minimum Measure Obligations by Another Entity. 
    An operator of a regulated small MS4 may
    
    [[Page 68767]]
    
    satisfy the requirement to implement one or more of the six minimum 
    measures in Sec. 122.34(b) by having a third party implement the 
    measure or measures. Today's rule provides a variety of means for small 
    MS4 operators to share responsibility for different aspects of their 
    storm water management program. The means by which the operators of 
    various MS4s share responsibility may affect who is ultimately 
    responsible for performance of the minimum measure and who files the 
    periodic reports on the implementation of the minimum measure. Section 
    122.35 addresses these issues. The rule describes two different 
    variants on third party implementation with different consequences if 
    the third party fails to implement the measure.
        If the permit covering the discharge from a regulated small MS4 
    identifies the operator as the entity responsible for a particular 
    minimum control measure, then the operator-permittee remains 
    responsible for the implementation of that measure even if another 
    entity has agreed to implement the control measure. Section 122.35(a). 
    Another party may satisfy the operator-permittee's responsibility by 
    implementing the minimum control measure in a manner at least as 
    stringent or prescriptive as the corresponding NPDES permit 
    requirement. If the third party fails to do so, the operator-permittee 
    remains responsible for its performance. The operator of the MS4 should 
    consider entering into an agreement with the third party that 
    acknowledges the responsibility to implement the minimum measure. The 
    operator-permittee's NOI and its annual Sec. 122.34(f)(3) reports 
    submitted to the NPDES permitting authority must identify the third 
    party that is satisfying one or more of the permit obligations. This 
    requirement ensures that the permitting authority is aware which entity 
    is supposed to implement which minimum measures.
        If, on the other hand, the regulated small MS4's permit recognizes 
    that an NPDES permittee other than the operator-permittee is 
    responsible for a particular minimum control measure, then the 
    operator-permittee is relieved from the responsibility for implementing 
    that measure. The operator-permittee is also relieved from the 
    responsibility for implementing any measure that the operator's permit 
    indicates will be performed by the NPDES permitting authority. Section 
    122.35(b). The MS4 operator-permittee would be responsible for 
    implementing the remaining minimum measures.
        Today's final rule differs from the proposed version of 
    Sec. 122.35(b), which stated that, even if the third party's 
    responsibility is recognized in the permit, the MS4 operator-permittee 
    remained responsible for performance if the third party failed to 
    perform the measure consistent with Sec. 122.34(b). Under today's rule, 
    the operator-permittee is relieved from responsibility for performance 
    of a measure if the third party is an NPDES permittee whose permit 
    makes it responsible for performance of the measure (including, for 
    example, a State agency other than the State agency that issues NPDES 
    permits) or if the third party is the NPDES permitting authority 
    itself. Because the permitting authority is acknowledging the third 
    party's responsibility in the permit, commenters thought that the MS4 
    operator-permittee should not be responsible for ensuring that the 
    other entity is implementing the control measure properly. EPA agrees 
    that the operator-permittee should not be conditionally responsible 
    when the requirements are enforceable against some other NPDES 
    permittee. If the third party fails to perform the minimum measure, the 
    requirements will be enforceable against the third party. In addition, 
    the NPDES permitting authority could reopen the operator-permittee's 
    permit under Sec. 122.62 and modify the permit to make the operator 
    responsible for implementing the measure. A new paragraph has been 
    added to Sec. 122.62 to clarify that the permit may be reopened in such 
    circumstances.
        Today's rule also provides that the operator-permittee is not 
    conditionally responsible where it is the State NPDES permitting 
    authority itself that fails to implement the measure. The permitting 
    authority does not need to issue a permit to itself (i.e., to the same 
    State agency that issues the permit) for the sole purpose of relieving 
    the small MS4 from responsibility in the event the State agency does 
    not satisfy its obligation to implement a measure. EPA does not believe 
    that the small MS4 should be responsible in the situation where the 
    NPDES permit issued to the small MS4 operator recognizes that the State 
    agency that issues the permit is responsible for implementing a 
    measure. If the State does fail to implement the measure, the State 
    agency could be held accountable for its commitment in the permit to 
    implement the measure. Where the State does not fulfill its 
    responsibility to implement a measure, a citizen also could petition 
    for withdrawal of the State's NPDES program or it could petition to 
    have the MS4's permit reopened to require the MS4 operator to implement 
    the measure.
        EPA notes that not every State program that addresses erosion and 
    sediment control from construction sites will be adequate to satisfy 
    the requirement that each regulated small MS4 have a program to the 
    extent required by Sec. 122.34(b)(4). For example, although all NPDES 
    States are required to issue NPDES permits for construction activity 
    that disturbs greater than one acre, the State's NPDES permit program 
    will not necessarily be extensive enough to satisfy a regulated small 
    MS4's obligation under Sec. 122.34(b)(4). NPDES States will not 
    necessarily be implementing all of the required elements of that 
    minimum measure, such as procedures for site plan review in each 
    jurisdiction required to develop a program and procedures for receipt 
    and consideration of information submitted by the public on individual 
    construction sites. In order for a State erosion and sediment control 
    program to satisfy a small MS4 operator's obligation to implement 
    Sec. 122.34(b)(4), the State program would have to include all of the 
    elements of that minimum measure.
        Where the operator-permittee is itself performing one or more of 
    the minimum measures, the operator-permittee remains responsible for 
    all of the reporting requirements under Sec. 122.34(f)(3). The 
    operator-permittee's reports should identify each entity that is 
    performing the control measures within the geographic jurisdiction of 
    the regulated small MS4. If the other entity also operates a regulated 
    MS4 and files reports on the progress of implementation of the measures 
    within the geographic jurisdiction of the MS4, then the operator-
    permittee need not include that same information in its own reports.
        If the other entity operates a regulated MS4 and is performing all 
    of the minimum measures for the permittee, the permittee is not 
    required to file the reports required by Sec. 122.34(f)(3). This relief 
    from reporting is specified in Sec. 122.35(a).
        Section 122.35 addresses the concerns of some commenters who sought 
    relief for governmental facilities that are classified as small MS4s 
    under today's rule. These facilities frequently discharge storm water 
    through another regulated MS4 and could be regulated by that MS4's 
    program. For example, a State owned office complex that operates its 
    storm sewer system in an urbanized area will be regulated as an MS4 
    under today's rule even though its system may be subject to the storm 
    water controls of the municipality in
    
    [[Page 68768]]
    
    which it is located. Today's rule specifically revised the definition 
    of MS4 to recognize that different levels of government often operate 
    MS4s and that each such separate entity (including the federal 
    government) should be responsible for its discharges. If both MS4s 
    agree, the downstream MS4 can develop a storm water management program 
    that regulates the discharge from both MS4s. The upstream small MS4 
    operator still must submit an NOI that identifies the entity on which 
    the upstream small MS4 operator is relying to satisfy its permit 
    obligations. No reports are required from the upstream small MS4 
    operator, but the upstream operator must remain in compliance with the 
    downstream MS4 operator's storm water management program. This option 
    allows small MS4s to work together to develop one storm water 
    management program that satisfies the permit obligations of both. If 
    they cannot agree, the upstream small MS4 operator must develop its own 
    program.
        As mentioned previously, comments from federal facilities and State 
    organizations that operate MS4s requested that their permit 
    requirements differ from those of MS4s that are political subdivisions 
    of States (cities, towns, counties, etc.). EPA acknowledges that there 
    are differences; e.g., many federal and State facilities do not serve a 
    resident population and thus might require a different approach to 
    public education. EPA believes, however, that MS4s owned by State and 
    federal governments can develop storm water management plans that 
    address the minimum measures. Federal and State owned small MS4s may 
    choose to work with adjacent municipally owned MS4s to develop a 
    unified plan that addresses all of the required measures within the 
    jurisdiction of all of the contiguous MS4s. The options in Sec. 122.35 
    minimize the burden on small MS4s that are covered by another MS4's 
    program.
        One commenter recommended that if one MS4 discharges into a second 
    MS4, the operator of the upstream MS4 should have to provide a copy of 
    its NOI or permit application to the operator of the receiving MS4. EPA 
    did not adopt this recommendation because the NOI and permit 
    application will be publicly available; but EPA does recommend that 
    NPDES permitting authorities consider it as a possible permit 
    requirement. The commenter also suggested that monitoring data should 
    be collected by the upstream MS4 and provided to the downstream MS4. 
    EPA is not adopting such a uniform monitoring requirement because EPA 
    believes it is more appropriate to let the MS4 operators work out the 
    need for such data. If necessary, the downstream MS4s might want to 
    make such data a condition to allowing the upstream MS4 to connect to 
    its system.
        v. Joint Permit Programs. Many commenters supported allowing the 
    operators of small MS4s to apply as co-permittees so they each would 
    not have to develop their own storm water management program. Today's 
    rule specifically allows regulated small MS4s to join with either other 
    small MS4s regulated under Sec. 122.34(d) or with medium and large MS4s 
    regulated under Sec. 122.26(d).
        As is discussed in the previous section, regulated small MS4s may 
    indicate in their NOIs that another entity is performing one or more of 
    its required minimum control measures. Today's rule under 
    Sec. 122.33(b)(1) also specifically allows the operators of regulated 
    small MS4s to jointly submit an NOI. The joint NOI must clearly 
    indicate which entity is required to implement which control measure in 
    each geographic jurisdiction within the service area of the entire 
    small MS4. The operator of each regulated small MS4 remains responsible 
    for the implementation of each minimum measure for its MS4 (unless, as 
    is discussed in the previous section above, the permit recognizes that 
    another entity is responsible for completing the measure.) The joint 
    NOI, therefore, is legally equivalent to each entity submitting its own 
    NOI. EPA is, however, revising the rule language to specifically 
    authorize the joint submission of NOIs in response to comments that 
    suggested that such explicit authorization might encourage programs to 
    be coordinated on a watershed basis.
        Section 122.33(b)(2)(iii) authorizes regulated small MS4s to 
    jointly apply for an individual permit to implement today's rule, where 
    allowed by an NPDES permitting authority. The permit application should 
    contain sufficient information to allow the permitting authority to 
    allocate responsibility among the parties under one of the two 
    permitting options in Secs. 122.33(b)(2)(i) and (ii).
        Section 122.33(b)(3) of today's rule also allows an operator of a 
    regulated small MS4 to join as a co-permittee in an existing NPDES 
    permit issued to an adjoining medium or large MS4 or source designated 
    under the existing storm water program. This co-permittee option 
    applies only with the agreement of all co-permittees. Under this co-
    permittee arrangement, the operator of the regulated small MS4 must 
    comply with the terms and conditions of the applicable permit rather 
    than the permit condition requirements of Sec. 122.34 of today's rule. 
    The regulated small MS4 that wishes to be a co-permittee must comply 
    with the applicable requirements of Sec. 122.26(d), but would not be 
    required to fulfill all the permit application requirements applicable 
    to medium and large MS4s. Specifically, the regulated small MS4 is not 
    required to comply with the application requirements of 
    Sec. 122.26(d)(1)(iii) 
    (Part 1 source identification), Sec. 122.26 (d)(1)(iv) (Part 1 
    discharge characterization), and Sec. 122.26(d)(2)(iii) (Part 2 
    discharge characterization data). Furthermore, the regulated small MS4 
    operator could satisfy the requirements in Sec. 122.26(d)(1)(v) (Part 1 
    management programs) and Sec. 122.26(d)(2)(iv) (Part 2 proposed 
    management program) by referring to the adjoining MS4 operator's 
    existing plan. An operator pursuing this option must describe in the 
    permit modification request how the adjoining MS4's storm water program 
    addresses or needs to be supplemented in order to adequately address 
    discharges from the MS4. The request must also explain the role of the 
    small MS4 operator in coordinating local storm water activities and 
    describe the resources available to accomplish the storm water 
    management plan.
        EPA sought comments regarding the appropriateness of the 
    application requirements in these subsections of Sec. 122.26(d). One 
    commenter stated that newly regulated smaller MS4s should not be 
    required to meet the existing regulations' Part II application 
    requirements under Sec. 122.26(d) regarding the control of storm water 
    discharges from industrial activity. EPA disagrees. The smaller MS4 
    operators designated for regulation in today's rule may satisfy this 
    requirement by referencing the legal authority of the already regulated 
    MS4 program to the extent the newly regulated MS4 will rely on such 
    legal authority to satisfy its permit requirements. If the smaller MS4 
    operator plans to rely on its own legal authorities, it must identify 
    it in the application. If the smaller MS4 operator does not elect to 
    use its own legal authority, they may file an individual permit 
    application for an alternate program under Sec. 122.33(b)(2)(ii).
        The explanatory language in Sec. 122.33(b)(3) recommends that the 
    smaller MS4s designated under today's rule identify how an existing 
    plan ``would need to be supplemented in order to adequately address 
    your discharges.'' One commenter suggested that this must be regulatory 
    language and not guidance. EPA disagrees that this needs to be 
    mandatory language.
    
    [[Page 68769]]
    
    Since many of the smaller MS4s designated today are ``donut holes'' 
    within the geographic jurisdiction of an already regulated MS4, the 
    larger MS4's program generally will be adequate to address the newly 
    regulated MS4's discharges. The small MS4 applicant should consider the 
    adequacy of the existing MS4's program to address the smaller MS4's 
    water quality needs, but EPA is not imposing specific requirements. 
    Where circumstances suggest that the existing program is inadequate 
    with respect to the newly designated MS4 and the applicant does not 
    address the issue, the NPDES permitting authority must require that the 
    existing program be supplemented.
        Commenters recommended that the application deadline for smaller 
    MS4s designated today be extended so that existing regulated MS4s would 
    not have to modify their permit in the middle of their permit term, 
    provided that permit renewal would occur within a reasonable time (12 
    to 18 months) of the deadline. In response, EPA notes that today's rule 
    allows operators of newly designated small MS4s up to three years and 
    90 days from the promulgation of today's rule to submit an application 
    to be covered under the permit issued to an already regulated MS4. The 
    permitting authority has a reasonable time after receipt of the 
    application to modify the existing permit to include the newly 
    designated source. If an existing MS4's permit is up for renewal in the 
    near future, the operator of a newly designated small MS4 may take that 
    into account when timing its application and the NPDES permitting 
    authority may take that into account when processing the application.
        Another commenter suggested that the rule should include a 
    provision to allow permit application requirements for smaller MS4s 
    designated today to be determined by the permitting authority to 
    account for the particular needs/wants of an already regulated MS4 
    operator. EPA does not believe that the regulations should specifically 
    require this approach. When negotiating whether to include a newly 
    designated MS4 in its program, the already regulated MS4 operator may 
    require the newly designated MS4's operator to provide any information 
    that is necessary.
        The co-permitting approach allows small MS4s to take advantage of 
    existing programs to ease the burden of creating their own programs. 
    The operators of regulated small MS4s, however, may find it simpler to 
    apply for a program under today's rule, and to identify the medium or 
    large MS4 operator that is implementing portions of its Sec. 122.34(b) 
    minimum measures.
    d. Evaluation and Assessment
        Under today's rule, operators of regulated small MS4s are required 
    to evaluate the appropriateness of their identified BMPs and progress 
    toward achieving their identified measurable goals. The purpose of this 
    evaluation is to determine whether or not the MS4 is meeting the 
    requirements of the minimum control measures. The NPDES permitting 
    authority is responsible for determining whether and what types of 
    monitoring needs to be conducted and may require monitoring in 
    accordance with State/Tribe monitoring plans appropriate to the 
    watershed. EPA does not encourage requirements for ``end-of-pipe'' 
    monitoring for regulated small MS4s. Rather, EPA encourages permitting 
    authorities to carefully examine existing ambient water quality and 
    assess data needs. Permitting authorities should consider a combination 
    of physical, chemical, and biological monitoring or the use of other 
    environmental indicators such as exceedance frequencies of water 
    quality standards, impacted dry weather flows, and increased flooding 
    frequency. (Claytor, R. and W. Brown. 1996. Environmental Indicators to 
    Assess Storm Water Control Programs and Practices. Center for Watershed 
    Protection, Silver Spring, MD.) Section II.L., Water Quality Issues, 
    discusses monitoring in greater detail.
        As recommended by the Intergovernmental Task Force on Monitoring 
    Water Quality (ITFM), the NPDES permitting authority is encouraged to 
    consider the following watershed objectives in determining monitoring 
    requirements: (1) To characterize water quality and ecosystem health in 
    a watershed over time, (2) to determine causes of existing and future 
    water quality and ecosystem health problems in a watershed and develop 
    a watershed management program, (3) to assess progress of watershed 
    management program or effectiveness of pollution prevention and control 
    practices, and (4) to support documentation of compliance with permit 
    conditions and/or water quality standards. With these objectives in 
    mind, the Agency encourages participation in group monitoring programs 
    that can take advantage of existing monitoring programs undertaken by a 
    variety of governmental and nongovernental entities. Many States may 
    already have a monitoring program in effect on a watershed basis. The 
    ITFM report is included in the docket for today's rule 
    (Intergovernmental Task Force on Monitoring Water Quality. 1995. The 
    Strategy for Improving Water-Quality Monitoring in the United States: 
    Final Report of the Intergovernmental Task Force on Monitoring Water 
    Quality. Copies can be obtained from: U.S. Geological Survey, Reston, 
    VA.).
        EPA expects that many types of entities will have a role in 
    supporting group monitoring activities--including federal agencies, 
    State agencies, the public, and various classes or categories of point 
    source dischargers. Some regulated small MS4s might be required to 
    contribute to such monitoring efforts. EPA expects, however, that their 
    participation in monitoring activities will be relatively limited. For 
    purposes of today's rule, EPA recommends that, in general, NPDES 
    permits for small MS4s should not require the conduct of any additional 
    monitoring beyond monitoring that the small MS4 may be already 
    performing. In the second and subsequent permit terms, EPA expects that 
    some limited ambient monitoring might be appropriately required for 
    perhaps half of the regulated small MS4s. EPA expects that such 
    monitoring will only be done in identified locations for relatively few 
    pollutants of concern. EPA does not anticipate ``end-of-pipe'' 
    monitoring requirements for regulated small MS4s.
        EPA received a wide range of comments on this section of the rule. 
    Some commenters believe that EPA should require monitoring; others want 
    a strong statement that the newly regulated small MS4s should not be 
    required to monitor. Many commenters raised questions about exactly 
    what EPA expects MS4s to do to evaluate and assess their BMPs. EPA has 
    intentionally written today's rule to provide flexibility to both MS4s 
    and permitting authorities regarding appropriate evaluation and 
    assessment. Permitting authorities can specify monitoring or other 
    means of evaluation when writing permits. If additional requirements 
    are not specified, MS4s can decide what they believe is the most 
    appropriate way to evaluate their storm water management program. As 
    mentioned above, EPA expects that the necessity for monitoring and its 
    extent may change from permit cycle to permit cycle. This is another 
    reason for making the evaluation and assessment rule requirements very 
    flexible.
        i. Recordkeeping. The NPDES permitting authority is required to 
    include at least the minimum appropriate recordkeeping conditions in 
    each permit. Additionally, the NPDES permitting authority can specify 
    that permittees develop, maintain, and/or
    
    [[Page 68770]]
    
    submit other records to determine compliance with permit conditions. 
    The MS4 operator must keep these records for at least 3 years but is 
    not required to submit records to the NPDES permitting authority unless 
    specifically directed to do so. The MS4 operator must make the records, 
    including the storm water management program, available to the public 
    at reasonable times during regular business hours (see 40 CFR 122.7 for 
    confidentiality provision). The MS4 operator is also able to assess a 
    reasonable charge for copying and to establish advance notice 
    requirements for members of the public.
        EPA received a comment that questioned EPA's authority to require 
    MS4s to make their records available to the public. EPA disagrees with 
    the commenter and believes that the CWA does give EPA the authority to 
    require that MS4 records be available. It is also more practical for 
    the public to request records directly from the MS4 than to request 
    them from EPA who would then make the request to the MS4. Based on 
    comments, EPA revised the proposed rule so as not to limit the time for 
    advance notice requirements to 2 business days.
        ii. Reporting. Under today's rule, the operator of a regulated 
    small MS4 is required to submit annual reports to the NPDES permitting 
    authority for the first permit term. For subsequent permit terms, the 
    MS4 operator must submit reports in years 2 and 4 unless the NPDES 
    permitting authority requires more frequent reports. EPA received 
    several comments supporting this timing for report submittal. Other 
    commenters suggested that annual reports during the first permit cycle 
    are too burdensome and not necessary. EPA believes that annual reports 
    are needed during the first 5-year permit term to help permitting 
    authorities track and assess the development of MS4 programs, which 
    should be established by the end of the initial term. Information 
    contained in these reports can also be used to respond to public 
    inquiries.
        The report must include (1) the status of compliance with permit 
    conditions, an assessment of the appropriateness of identified BMPs and 
    progress toward achieving measurable goals for each of the minimum 
    control measures, (2) results of information collected and analyzed, 
    including monitoring data, if any, during the reporting period, (3) a 
    summary of what storm water activities the permittee plans to undertake 
    during the next reporting cycle, and (4) a change in any identified 
    measurable goal(s) that apply to the program elements.
        The NPDES permitting authority is encouraged to provide a brief 
    two-page reporting format to facilitate compiling and analyzing the 
    data from submitted reports. EPA does not believe that submittal of a 
    brief annual report of this nature is overly burdensome, and has not 
    changed the required reporting time frame from the proposal. The 
    permitting authority will use the reports in evaluating compliance with 
    permit conditions and, where necessary, will modify the permit 
    conditions to address changed conditions.
        iii. Permit-As-A-Shield. Section 122.36 describes the scope of 
    authorization (i.e. ``permit-as-a-shield'') under an NPDES permit as 
    provided by section 402(k) of the CWA. Section 402(k) provides that 
    compliance with an NPDES permit is deemed compliance, for purposes of 
    enforcement under CWA sections 309 and 505, with CWA sections 301, 302, 
    306, 307, and 403, except for any standard imposed under section 307 
    for toxic pollutants injurious to human health.
        EPA's Policy Statement on Scope of Discharge Authorization and 
    Shield Associated with NPDES Permits, originally issued on July 1, 
    1994, and revised on April 11, 1995, provides additional information on 
    this matter.
    e. Other Applicable NPDES Requirements
        Any NPDES permit issued to an operator of a regulated small MS4 
    must also include other applicable NPDES permit requirements and 
    standard conditions, specifically the applicable requirements and 
    conditions at 40 CFR 122.41 through 122.49. Reporting requirements for 
    regulated small MS4s are governed by Sec. 122.34 and not the existing 
    requirements for medium and large MS4s at Sec. 122.42(c). In addition, 
    the NPDES permitting authority is encouraged to consult the Interim 
    Permitting Approach, issued on August 1, 1996. The discussion on the 
    Interim Permitting Approach in Section II.L.1, Water Quality Based 
    Effluent Limits, provides more information. The provisions of 
    Secs. 122.41 through 122.49 establish permit conditions and limitations 
    that are broadly applicable to the entire range of NPDES permits. These 
    provisions should be interpreted in a manner that is consistent with 
    provisions that address specific classes or categories of discharges. 
    For example, Sec. 122.44(d) is a general requirement that each NPDES 
    permit shall include conditions to meet water quality standards. This 
    requirement will be met by the specific approach outlined in today's 
    rule for the implementation of BMPs. BMPs are the most appropriate form 
    of effluent limitations to satisfy technology requirements and water 
    quality-based requirements in MS4 permits (see the introduction to 
    Section II.H.3, Municipal Permit Requirements, Section II.H.3.h, 
    Reevaluation of Rule, and the discussion of the Interim Permitting 
    Policy in Section II.L.1. below).
    f. Enforceability
        NPDES permits are federally enforceable. Violators may be subject 
    to the enforcement actions and penalties described in CWA sections 309, 
    504, and 505 or under similar water pollution enforcement provisions of 
    State, tribal or local law. Compliance with a permit issued pursuant to 
    section 402 of the Clean Water Act is deemed compliance, for purposes 
    of sections 309 and 505, with sections 301, 302, 306, 307, and 403 
    (except any standard imposed under section 307 for toxic pollutants 
    injurious to human health).
    g. Deadlines
        Today's final rule includes ``expeditious deadlines'' as directed 
    by CWA section 402(p)(6). In proposed Sec. 122.26(e), the permit 
    application for the ``ISTEA'' facilities was maintained as August 7, 
    2001 and the permit application deadline for storm water discharges 
    associated with other construction activity was established as 3 years 
    and 90 days from the final rule date. In proposed Sec. 122.33(c)(1), 
    operators of regulated small MS4s were required to seek permit coverage 
    within 3 years and 90 days from the date of publication of the final 
    rule. In proposed Sec. 122.33(c)(2), operators of regulated small MS4s 
    designated by the NPDES permitting authority on a local basis under 
    Sec. 122.32(a)(2) must seek coverage under an NPDES permit within 60 
    days of notice, unless the NPDES permitting authority specifies a later 
    date.
        In order to increase the clarity of today's final rule, EPA has 
    changed the location of some of the above requirements. All application 
    deadlines for both Phase I and Phase II are now listed or referenced in 
    Sec. 122.26(e). Section 122.26(e)(1) contains the deadlines for storm 
    water associated with industrial activity. Paragraph (i) has been 
    changed to correct a typographical error. Paragraph (ii) has been 
    revised to reflect the changed application date for ``ISTEA'' 
    facilities. (See discussion in section I.3, ISTEA Sources). The 
    application deadline for storm water discharges associated with other 
    construction activity is now in a new Sec. 122.26(e)(8). The 
    application deadline for regulated small MS4s
    
    [[Page 68771]]
    
    remains in Sec. 122.33(c) because this section is written in ``readable 
    regulation'' format, but it is also described in a new 
    Sec. 122.26(e)(9).
        Under today's rule, permitting authorities are allowed up to 3 
    years to issue a general permit and MS4s designated under 
    Sec. 122.32(a)(1) are allowed up to 3 years and 90 days to submit a 
    permit application. Operators of regulated small MS4s that choose to be 
    a co-permittee with an adjoining MS4 with an existing NPDES storm water 
    permit must apply for a modification of that permit within the same 
    time frame. Several commenters stated that 90 days was not adequate 
    time to submit an NOI. This might be true if facilities did not start 
    developing their storm water program until publication of their general 
    permit. In fact, municipalities should start developing their storm 
    water program upon publication of today's final rule, if they have not 
    already done so. Municipalities that are uncertain if they fall within 
    the urbanized area should ask their permitting authority. EPA believes 
    that municipalities should not automatically take three years and 90 
    days to develop a program and submit their NOI. Three years is the 
    maximum amount of time to issue a general permit. MS4s that are 
    automatically designated under today's rule may have less than 3 years 
    and 90 days if the permitting authority issues a permit that requires 
    submission of NOIs before that time. EPA encourages States to modify 
    their NPDES program to include storm water and issue their permits as 
    soon as possible. It is important for permitting authorities to keep 
    their municipalities informed of their progress in developing or 
    modifying their NPDES storm water requirements.
        EPA recognizes that MS4s brought into the program due to the 2000 
    Census calculations do not have as much time to develop a program as 
    those already designated from the 1990 Census. However, the official 
    Bureau of the Census urbanized area calculation for the 2000 Census is 
    expected to be published in the Federal Register in the spring of 2002, 
    which should give the potentially affected MS4s adequate time to 
    prepare for compliance under the applicable permit. However, if the 
    publication of this information is delayed, MS4s in newly designated 
    urbanized areas will have 180 days from the time the new designations 
    are published to submit an NOI, consistent with the time frame for 
    other regulated MS4s that are designated after promulgation of the 
    rule.
        The proposed application deadline for MS4s designated under 
    Sec. 122.32(a)(2) was within 60 days of notice. Many commenters stated 
    that 60 days does not provide adequate time for the preparation of an 
    NOI or permit application. EPA agrees that newly designated MS4s may 
    not be aware that they might be designated since the permitting 
    authority could take several years to develop designation criteria. EPA 
    has decided that the application time frame for these facilities should 
    be consistent with the 180 days allowed for facilities designated under 
    Secs. 122.26(a)(9)(i)(C) and (D). Section 122.33(c)(2) of today's final 
    rule contains the modified time frame of 180 days to apply for 
    coverage.
    h. Reevaluation of Rule
        The municipal caucus of the Storm Water Phase II FACA Subcommittee 
    asked EPA to demonstrate its commitment to revisit the municipal 
    requirements of today's rule and make changes where necessary after 
    evaluating the storm water program and researching the effectiveness of 
    municipal BMPs. In Sec. 122.37 of today's final rule, EPA commits to 
    revisiting the regulations for the municipal storm water discharge 
    control program after completion of the first two permit terms. EPA 
    intends to use this time to work closely with stakeholders on research 
    efforts. Gathering and analyzing data related to the storm water 
    program, including data regarding the effectiveness of BMPs, is 
    critical to EPA's storm water program evaluation. EPA does not intend 
    to change today's NPDES municipal storm water program until the end of 
    this period, except under the following circumstances: a court decision 
    requires changes; a technical change is necessary for implementation; 
    or the CWA is modified, thereby requiring changes. After careful 
    analysis, EPA might also consider changes from consensus-based 
    stakeholder requests regarding requirements applicable to newly 
    regulated MS4s. EPA will apply the August 1, 1996, Interim Permitting 
    Approach to today's program during this interim period and encourages 
    all permitting authorities to use this approach in municipal storm 
    water permits for newly regulated MS4s and in determining MS4 permit 
    requirements under a TMDL approach. After careful consideration of the 
    data, EPA will make modifications as necessary.
        EPA received comments that supported waiting two permit cycles 
    before re-evaluating the rule and other comments that requested re-
    evaluation much sooner. EPA anticipates two full permit cycles are 
    necessary to obtain enough data to significantly evaluate the rule. The 
    re-evaluation time frame of 13 years from today remains as proposed.
    
    I. Other Designated Storm Water Discharges
    
    1. Discharges Associated with Small Construction Activity
        Section 122.26(b)(15) of today's rule designates certain 
    construction activities for regulation as ``storm water discharges 
    associated with small construction activity.'' Specifically, storm 
    water discharges from construction activity equal to or greater than 1 
    acre and less than 5 acres are automatically designated except in those 
    circumstances where the operator (i.e., person responsible for 
    discharges that might occur) certifies to the permitting authority that 
    one of two specific waiver circumstances (described in section b. 
    below) applies. Sites below one acre may be designated under 
    Sec. 122.26(b)(15)(ii) where necessary to protect water quality.
        Today's rule regulates these construction-related storm water 
    sources under CWA section 402(p)(6) to protect water quality rather 
    than under CWA section 402(p)(2). Designation under 402(p)(6) gives 
    States and EPA the flexibility to waive the permit requirement for 
    construction activity that is not likely to impair water quality, and 
    to designate additional sources below one acre that are likely to cause 
    water quality impairment. Thus, the one acre threshold of today's rule 
    is not an absolute threshold like the five acre threshold that applies 
    under the existing storm water rule.
        Today's rule regulating certain storm water discharges from 
    construction activity disturbing less than 5 acres is consistent with 
    the 9th Circuit remand in NRDC v. EPA, 966 F.2d 1292 (9th Cir. 1992). 
    In that case, the court remanded portions of the existing storm water 
    regulations related to discharges from construction sites. The existing 
    Phase I regulations define ``storm water discharges associated with 
    industrial activity'' to include storm water discharges from 
    construction sites disturbing 5 acres or more of total land area (see 
    40 CFR 122.26(b)(14)(x)). In its decision, the court concluded that the 
    5-acre threshold was improper because the Agency had failed to identify 
    information ``to support its perception that construction activities on 
    less than 5 acres are non-industrial in nature'' (966 F.2d at 1306). 
    The court remanded the exemption to EPA for further proceedings (966 
    F.2d at 1310). EPA's objectives in today's action include an effort to 
    (1) address the 9th Circuit
    
    [[Page 68772]]
    
    remand to reconsider regulation of storm water discharges from 
    construction activities that disturb less than 5 acres of land, (2) 
    address water quality concerns associated with such activities, and (3) 
    balance conflicting recommendations and concerns of stakeholders in the 
    regulation of additional construction activity.
        EPA responded to the Ninth Circuit's decision by designating 
    discharges from construction activities that disturb between 1 and 5 
    acres as ``discharges associated with small construction activity'' 
    under CWA section 402(p)(6), rather than as ``discharges associated 
    with industrial activity'' under CWA section 402(p)(2)(B). Although a 
    size criterion alone may be an indicator of whether runoff from 
    construction sites between 1 and 5 acres is ``associated with 
    industrial activity,'' the Agency is instead relying on a size 
    threshold in tandem with provisions that allow for designations and 
    waivers based on potential for ``predicted water quality impairments'' 
    to regulate construction sites between 1 and 5 acres under CWA section 
    402(p)(6). This approach was chosen by the Agency for the sake of 
    simplicity and certainty and, most importantly, to protect water 
    quality consistent with the mandate of CWA section 402(p)(6). Today's 
    rule also includes extended application deadlines for this new category 
    of dischargers under the authority of CWA section 402(p)(6) (see 
    Sec. 122.26(e)(8) of today's rule).
        In today's rule, EPA is regulating storm water discharges from 
    additional construction sites to better protect the Nation's waters, 
    while remaining sensitive to a concern that the Agency should not 
    regulate discharges from construction sites that might not or do not 
    have adverse water quality impacts. EPA believes that today's rule will 
    successfully accomplish this objective by establishing a 1-acre 
    threshold nationwide that includes the flexibility to allow the 
    permitting authority to both waive requirements for discharges from 
    sites that are not expected to cause adverse water quality impacts and 
    to designate discharges from sites below 1-acre based on adverse water 
    quality impacts.
        In addition to the diminishing water quality benefits of regulating 
    all sites below one acre, the Agency relied on practical considerations 
    in establishing a one acre threshold and not setting a lower threshold. 
    Regardless of the threshold established by EPA, a NPDES permit can only 
    be required if a construction site has a point source discharge. A 
    point source discharge means that pollutants are added to waters of the 
    United States through a discernible, confined, discrete conveyance. 
    ``Sheet flow'' runoff from a small construction site would not result 
    in a point source discharge unless and until it channelized. As the 
    amount of disturbed land surface decreases, precipitation is less 
    likely to channelize and create a ``point source'' discharge (assuming 
    the absence of steep slopes or other factors that lead to increased 
    channelization). Categorical designation of very small sites may create 
    confusion about applicability of the NPDES permitting program to those 
    sites. EPA's one acre threshold reflects, in part, the need to 
    recognize that smaller sites are less likely to result in point source 
    discharges. Of course, the NPDES permitting authority could designate 
    smaller sites (below one acre, assuming point source discharges occur 
    from the smaller designated sites) for regulation if a watershed or 
    other local assessment indicated the need to do so. The Phase II rule 
    includes this designation authority at 40 CFR 122.26(a)(9)(i)(D) and 
    (b)(15)(ii).
        The one acre threshold also provides an administrative tool for 
    more easily identifying those sites that are identified for coverage by 
    the rule (but may receive a waiver) and those that are not 
    automatically covered (but may be designated for inclusion). Although 
    all construction sites less than five acres could have a significant 
    water quality impact cumulatively, EPA is automatically designating for 
    permit coverage only those storm water discharges from construction 
    sites that disturb land equal to or greater than one acre. Categorical 
    regulation of discharges from construction below this one acre 
    threshold would overwhelm the resources of permitting authorities and 
    might not yield corresponding water quality benefits. Construction 
    activities that disturb less than one acre make up, in total, a very 
    small percentage of the total land disturbance from construction 
    nationwide. The one acre threshold is reasonable for accomplishing the 
    water quality goals of CWA section 402(p)(6) because it results in 
    97.5% of the total acreage disturbed by construction being designated 
    for coverage by the NPDES storm water program, while excluding from 
    automatic coverage the numerous smaller sites that represent 24.7% of 
    the total number of construction sites.
        Some commenters believed that EPA has not adequately identified 
    water quality problems associated with storm water discharges from 
    construction activity disturbing less than five acres. Other commenters 
    believed that storm water discharges from small construction activity 
    is a significant water quality problem nationwide. Section I.B.3, 
    Construction Site Runoff, provides a detailed discussion of adverse 
    water quality impacts resulting from construction site storm water 
    discharges. EPA is regulating storm water discharges from construction 
    activity disturbing between 1 and 5 acres because the cumulative impact 
    of many sources, and not just a single identified source, is typically 
    the cause for water quality impairments, particularly for sediment-
    related water quality standards.
        Several commenters requested that EPA regulate discharges from 
    small construction activity as ``discharges associated with industrial 
    activity'' under CWA 402(p)(4) and not, as proposed, as ``storm water 
    discharges associated with other activity'' under CWA 402(p)(6). EPA is 
    regulating discharges from small construction sites as ``small 
    construction activity'' under the authority of CWA section 402(p)(6), 
    rather than section 402(p)(4), to ensure that regulation of these 
    sources is water quality-sensitive. CWA section 402(p)(6) affords the 
    opportunity for designations and waivers of sources based on potential 
    for ``predicted water quality impairments.'' Regulation of storm water 
    ``associated with industrial activity'' does not necessarily focus 
    regulation to protect water quality.
    a. Scope
        The definition of ``storm water discharges associated with small 
    construction activity'' includes discharges from construction 
    activities, such as clearing, grading, and excavating activities, that 
    result in the disturbance of equal to or greater than 1 acre and less 
    than 5 acres (see Sec. 122.26(b)(15)(i)). Such activities could 
    include: road building; construction of residential houses, office 
    buildings, or industrial buildings; or demolition activity. The 
    definition of ``storm water discharges associated with small 
    construction activity'' also includes any other construction activity, 
    regardless of size, designated based on the potential for contribution 
    to a violation of a water quality standard or for significant 
    contribution of pollutants to waters of the United States 
    (Sec. 122.26(b)(15)(ii)). This designation is made by the Director, or 
    in States with approved NPDES programs, either the Director or the EPA 
    Regional Administrator.
        For the purposes of today's rule, the definition of ``storm water 
    discharges associated with small construction activity'' includes 
    discharges from activities disturbing less than 1 acre if that 
    construction activity is part of a
    
    [[Page 68773]]
    
    ``larger common plan of development or sale'' with a planned 
    disturbance of equal to or greater than 1 acre of land. A ``larger 
    common plan of development or sale'' means a contiguous area where 
    multiple separate and distinct construction activities are planned to 
    occur at different times on different schedules under one plan, e.g., a 
    housing development of five \1/4\ acre lots (Sec. 122.26(b)(15)(i)).
        In addition to the regulatory text for smaller construction, the 
    Agency is also revising the existing text of Sec. 122.26(b)(14)(x) to 
    clarify EPA's intention regarding construction projects involving a 
    larger common plan of development or sale ultimately disturbing 5 or 
    more acres. Operators of such sites are required to seek coverage under 
    an NPDES permit regardless of the number of lots in the larger plan 
    because designation for permit coverage is based on the total amount of 
    land area to be disturbed under the common plan. This designation 
    attempts to address the potential cumulative effects of numerous 
    construction activities concentrated in a given area.
        Several commenters asked that EPA allow the permitting authority to 
    set the appropriate size threshold based on water quality studies. 
    While EPA agrees that location-specific water quality studies provide 
    an ideal information base from which to make regulatory decisions, 
    today's rule establishes a default standard for regulation in the 
    absence of location-specific studies. The rule does allow for deviation 
    from the default standard through additional designations and waivers, 
    however, when supported by location-specific water quality information. 
    The rule codifies the ability of permitting authorities to provide 
    waivers for sites greater than or equal to one acre (the default 
    standard) and designate additional discharges from small sites below 
    one acre when location-specific information suggests that the default 1 
    acre standard is either unnecessary (waivers) or too limited 
    (designations) to protect water quality.
        Some commenters wanted EPA to base the regulation of storm water 
    discharges from construction sites not only on size, but also on the 
    duration and intensity of activity occurring on the site. EPA believes 
    that a national 1-acre threshold, in combination with waivers and 
    additional designations, is the most effective and simplest way to 
    address adverse water quality impacts from storm water from small 
    construction sites. Moreover, as discussed below, the waiver for 
    rainfall erosivity does account for projects of limited duration. EPA 
    believes, however, that the intensity of activity occurring on-site 
    would be a very difficult condition to quantify.
        Many commenters requested that EPA maintain the 5 acre threshold 
    from the existing regulations, which include opportunities for site-
    specific designation, as the regulatory scope for regulating storm 
    water from construction sites, i.e., that the Agency not automatically 
    regulate storm water discharges from sites less than 5 acres. Several 
    commenters wanted construction requirements to be applied to sites 
    smaller than 1 acre, while some commenters suggested alternative 
    thresholds of 2 or 3 acres. The rest of the commenters supported the 1 
    acre threshold. None of the commenters presented any data or rationales 
    to support a specific size threshold.
        EPA examined alternative size thresholds, including 0.5 acre, 1 
    acre, 2 acres and 5 acres. EPA had difficulty evaluating the 
    alternative size thresholds because, while directly proportional to the 
    size of the disturbed site, the water quality threat posed by 
    discharges from construction sites of differing sizes varies 
    nationwide, depending on the local climatological, geological, 
    geographical, and hydrological influences. In order to ensure 
    improvements in water quality nationwide, however, today's rule does 
    not allow various permitting authorities to establish different size 
    thresholds except based on the waiver and designation provisions of the 
    rule. EPA believes that the water quality impact from small 
    construction sites is as high as or higher than the impact from larger 
    sites on a per acre basis. By selecting the 1 acre size threshold and 
    coupling it with waivers and additional designations, EPA is seeking to 
    standardize improvement of water quality on a national basis while 
    providing permitting authorities with the opportunity to designate 
    those unregulated activities causing water quality impairments 
    regardless of site size, as well as to waive requirements when 
    information demonstrates that regulation is unnecessary.
        EPA recognizes that the size criterion alone may not be the most 
    ideal predictor of the need for regulation, but effective protection of 
    water quality depends as much on simplicity in implementation as it 
    does on the scientific information underlying the regulatory criteria. 
    The default size criterion of 1 acre will ensure protection against 
    adverse water quality impacts from storm water from small construction 
    sites while not overburdening the resources of permitting authorities 
    and the construction industry to implement the program to protect water 
    quality in the first place.
        One commenter stated a need to clarify whether routine road 
    maintenance is considered construction activity for the purpose of 
    today's rule. The NPDES general permit for discharges from construction 
    sites larger than 5 acres defined ``commencement of construction'' as 
    the initial disturbance of soils associated with clearing, grading, or 
    excavating activities or other construction activities (63 FR 7913). 
    For construction sites disturbing less than 5 acres, EPA does not 
    consider construction activity to include routine maintenance performed 
    to maintain the original line and grade, hydraulic capacity, or 
    original purpose of the facility.
        Two commenters believed that the Multi-Sector General Permit for 
    storm water discharges from industrial activities (MSGP) (60 FR 50804) 
    already applies to storm water discharges from construction activities 
    at oil and gas exploration and production sites and asked for a 
    clarification on this issue. Commenters also requested a single general 
    permit to authorize both industrial storm water discharges and 
    construction site discharges which occur at the same industrial site.
        Currently, when construction activity disturbing more than 5 acres 
    occurs on an industrial site covered by the MSGP, authorization under a 
    separate NPDES construction permit is needed because the MSGP does not 
    include the ``construction'' industrial sector. While the MSGP does 
    address sediment and erosion control, it is not as specific as the 
    NPDES general permit for storm water discharges from construction 
    activities disturbing more than 5 acres. Though permitting authorities 
    could conceivably develop a single general permit to authorize storm 
    water discharges associated with construction activity at these 
    industrial facilities, the commenter's request is not addressed by 
    today's rulemaking. When today's rule is implemented through general 
    permits (to be issued later), the permitting authority will have 
    discretion whether or not to incorporate the permit requirements for 
    both the industrial storm water discharges and construction site storm 
    water discharges into a single general permit. This type of request 
    should be addressed to the permitting authority.
        One commenter suggested that discharges from small construction 
    sites should be regulated through a ``self-implementing rule'' 
    approach. While today's rule is not a self-implementing rule, it does 
    add Sec. 122.28(b)(2)(v), which
    
    [[Page 68774]]
    
    gives the permitting authority the discretion to authorize a 
    construction general permit for sites less than 5 acres without 
    submitting a notice of intent. Such non-registration general permits 
    function similarly to self-implementing rules, but are, in fact, 
    permits. Today's rule will be implemented through NPDES permits rather 
    than self-implementing regulations to capitalize on the compliance, 
    tracking, enforcement, and public participation associated with NPDES 
    permits (see discussion in section II.C).
        Other commenters believed that only the permitting authority should 
    regulate construction site storm water discharges (under a NPDES 
    permit) and that a small MS4 operator's regulation of storm water 
    discharges associated with construction (under the small MS4 NPDES 
    storm water program) is redundant. EPA disagrees that control measure 
    implementation by the NPDES authority and the small MS4 operator is 
    redundant. To the extent the two efforts overlap, today's rule provides 
    for consolidation and coordination of substantive requirements via 
    incorporation by reference permitting. Small MS4s operators may choose 
    to impose more prescriptive requirements than an NPDES permitting 
    authority based on localized water quality needs. In those cases, EPA 
    intends that the substantive requirements from the small MS4 program 
    should apply as the NPDES permit requirements for the construction site 
    discharger. In cases where a small MS4 program does not prioritize and 
    focus on storm water from construction sites (beyond the small MS4 
    minimum control measure in today's rule, which does not require the 
    small MS4 operator to control construction site discharges in a manner 
    as prescriptive as is expected for discharges regulated under NPDES 
    permits), the Agency intends that the NPDES general permit will provide 
    the substantive standards applicable to the construction site 
    discharge. EPA does anticipate, however, that implementation of MS4 
    programs to address construction site runoff within their jurisdiction 
    will enhance overall NPDES compliance by construction site dischargers. 
    EPA also notes that under Sec. 122.35(b), the permitting authority may 
    recognize its own program to control storm water discharges from 
    construction sites in lieu of requiring such a program in an MS4's 
    NPDES permit, provided that the permitting authority's program 
    satisfies the requirements of Sec. 122.34(b)(4), including, for 
    example, procedures for site plan reviews and consideration of 
    information submitted by the public on individual construction sites in 
    each jurisdiction required to be covered by the program.
    b. Waivers
        Under Sec. 122.26(b)(15)(i) of today's rule, NPDES permitting 
    authorities may waive today's requirement for construction site 
    operators to obtain a permit in two circumstances. The first waiver is 
    intended to apply where little or no rainfall is expected during the 
    period of construction. The second waiver may be granted when a TMDL or 
    equivalent analysis indicates that controls on construction site 
    discharges are not needed to protect water quality.
        The first waiver is based on ``low predicted rainfall erosivity'' 
    which can be found using tables of rainfall-runoff erosivity (R) values 
    published for each region in the U.S. R factors are published in the 
    U.S. Department of Agriculture (USDA) Agricultural Handbook 703 
    (Renard, K.G., Foster, G.R., Weesies, G.A., McCool, D.K., and D.C. 
    Yoder. 1997. Predicting Soil Erosion by Water: A Guide to Conservation 
    Planning with the Revised Universal Soil Loss Equation (RUSLE). U.S. 
    Department of Agriculture Handbook 703). The R factor varies based on 
    the time during the year when construction activity occurs, where in 
    the country it occurs, and how long the construction activity lasts. 
    The permitting authority may determine, using Handbook 703, which times 
    of year, if any, the waiver opportunity is available for construction 
    activity. EPA will provide assistance either through computer programs 
    or the World Wide Web on how to determine whether this waiver applies 
    for a particular geographic area and time period. Application of this 
    waiver for regulatory purposes will be determined by the authorized 
    NPDES authority. This waiver is discussed further in the following 
    section titled Rainfall-Erosivity Waiver.
        The second waiver is based on a consideration of ambient water 
    quality. This waiver is available after a State or EPA develops and 
    implements TMDLs for the pollutant(s) of concern from storm water 
    discharges associated with construction activity. This waiver is also 
    available for sites discharging to non-impaired waters that do not 
    require TMDLs, when an equivalent analysis has determined allocations 
    for small construction sites for the pollutant(s) of concern or 
    determined that such allocations are not needed to protect water 
    quality based on consideration of existing in-stream concentrations, 
    expected growth in pollutant contributions from all sources, and a 
    margin of safety. The Agency envisions an equivalent analysis that 
    would demonstrate that water quality is not threatened by storm water 
    discharges from small construction activity. This waiver is discussed 
    further below in the sections titled TMDL Waiver and Water Quality 
    Issues.
        The proposed rule included a waiver based on ``low predicted soil 
    loss.'' This waiver provision would have been applicable on a case-by-
    case basis where the annual soil loss rate for the period of 
    construction for a site, using the Revised Universal Soil Loss Equation 
    (RUSLE), would be less than 2 tons/acre/year. The annual soil loss rate 
    of less than 2 tons/acre/year would be calculated through the use of 
    the RUSLE equation, assuming the constants of no ground cover and no 
    runoff controls in place.
        Several commenters found the low soil loss waiver too complex and 
    impractical, and stated that expertise is not available at the local 
    level to prepare and evaluate eligibility for the waiver. Another 
    commenter questioned whether two tons/acre/year was an appropriate 
    threshold for predicting adverse water quality impacts. Two other 
    commenters said that RUSLE was never intended to predict off-site 
    impacts and is not an indicator of potential harm to water quality. EPA 
    agrees with the commenters on the difficulty associated with 
    determining and implementing this waiver. Most construction site 
    operators are not familiar with the RUSLE program, and the potential 
    burden on the permitting authority, construction industry, USDA's 
    Natural Resources Conservation Service and conservation districts 
    probably would have been significant. The Agency has not included this 
    waiver in the final rule.
        Two commenters asked that EPA allow States the flexibility to 
    develop their own waiver criteria but did not suggest how the Agency 
    (or affected stakeholders) could evaluate the acceptability of 
    alternative State waiver criteria. Therefore, the final rule does not 
    provide for any such alternative waivers. If a State does seek to 
    develop alternate waiver criteria, then EPA procedures afford the 
    opportunity for subsequent actions, for example, under the Project XL 
    Program in EPA's Office of Reinvention, which seeks cleaner, smarter, 
    and cheaper solutions to environmental problems. Many commenters 
    suggested that EPA extend these waivers to existing industrial storm 
    water regulations for construction activity greater than 5 acres. These 
    construction site discharges are
    
    [[Page 68775]]
    
    regulated as industrial storm water discharges under CWA 402(p)(2) and 
    are not eligible for such water quality-based waivers.
        Two commenters were concerned that waivers would create a potential 
    for significant degradation of small streams. EPA disagrees. If small 
    streams are threatened, the permitting authority would choose not to 
    provide any waivers. In addition, permitting authorities may protect 
    small streams by designating discharges from small construction 
    activity based on the potential for contribution to a violation of a 
    water quality standard or for significant contribution of pollutants to 
    waters of the U.S.
        Two commenters asked that the waiver options be eliminated. They 
    felt it would create a gross inequity within the construction community 
    if some projects will not be subject to the requirements of today's 
    rule. While the comments may be valid, EPA disagrees that waivers 
    should be disallowed on this basis. Construction site discharges that 
    qualify for a waiver from permitting requirements are not expected to 
    present a threat to water quality, which is the basis for designation 
    and regulation under today's rule.
        A number of commenters suggested additional waivers in cases where 
    new development will result in no additional adverse impacts to water 
    quality as compared to the existing development it replaces. EPA 
    believes these waivers are either unworkable or unnecessary. It would 
    be very difficult for most construction operators to determine, as well 
    as for other stakeholders to verify, on a site-by-site basis, that 
    there is no potential for adverse impact to water quality compared to 
    the replaced development.
        Other commenters proposed waivers in cases where a local erosion 
    and sediment control program covers the project or a separate waiver 
    for small linear utility projects. Instead of waivers, today's rule 
    addresses the first suggestion through the qualifying program provision 
    described in the section titled Cross-Referencing State/Local Erosion 
    and Sediment Control Programs below. Today's rule provides waivers for 
    small linear projects in so far as they satisfy conditions for low 
    rainfall erosivity. (See Sec. 122.26(b)(15)(i)(A).)
        Other commenters suggested waivers based on distance to water body, 
    existence of vegetated buffer around water body, slope of disturbed 
    land, or if discharging to very large bodies of water. As a result of 
    public outreach, EPA believes that these proposed waivers would be 
    generally unworkable for construction site dischargers and permitting 
    authorities because of the difficulty in applying them to all small 
    sites.
        One commenter mentioned that waivers for the R factor (rainfall-
    erosivity) and soil loss are effluent standards that have not been 
    developed in accordance with sections 301 and 304 of the CWA. EPA 
    disagrees that these sections are relevant to the designation of 
    sources in today's rule. The waiver provisions in this section of the 
    rule are jurisdictional because they affect the scope of the universe 
    of entities subject to the NPDES program. Therefore, the waiver 
    provisions are not themselves substantive control standards implemented 
    through NPDES permits, and thus, not subject to the statutory criteria 
    in sections 301 and 304.
        Another commenter stated that waivers would allow exemptions to the 
    technology based requirements and would thus be inconsistent with the 
    two-fold approach of the CWA (a technology based minimum and a water 
    quality based overlay). EPA acknowledges that the CWA does not 
    generally provide for waivers for the Act's technology-based 
    requirements. The waiver provisions do not create exemptions from 
    technology-based standards that apply to NPDES dischargers; they 
    provide exemption from the underlying requirement for an NPDES permit 
    in the first place. Protection of water quality is the reason these 
    smaller sites are designated for regulation under NPDES. The Act's two 
    fold approach imposes more stringent water quality based effluent 
    limitations when technology-based limitations applicable to regulated 
    dischargers are insufficient to meet water quality standards. Under 
    today's rule, water quality protection is the basis for determining 
    which of the unregulated sources should be regulated at all. Thus, 
    today's rule is entirely consistent with the Act's two fold approach.
        i. Rainfall-Erosivity Waiver. The rainfall-erosivity waiver under 
    Sec. 122.26(b)(15)(i)(A) is intended to exempt the requirements for a 
    permit when and where negligible rainfall/runoff-erosivity is expected. 
    In the development of the Universal Soil Loss Equation, analysis of 
    data indicated that when factors other than rainfall are held constant, 
    soil loss is directly proportional to a rainfall factor composed of 
    total storm kinetic energy times the maximum 30 minute intensity. The 
    average annual sum of the storm energy and intensity values for an area 
    comprise the R factor--the rainfall erosivity index. A detailed 
    explanation of the R factor can be found in Predicting Soil Erosion by 
    Water: A Guide to Conservation Planning With the Revised Universal Soil 
    Loss Equation (RUSLE) (USDA, 1997).
        This waiver is time-sensitive and is dependent on when during the 
    year a construction activity takes place, how long it lasts, and the 
    expected rainfall and intensity during that time. R factors vary based 
    on location. EPA anticipates that this waiver opportunity responds to 
    concerns about the requirement for a permit when it is not expected to 
    rain, especially in the arid areas of the U.S. Under today's rule, the 
    permitting authority could waive the requirements for a permit for time 
    periods when the rainfall-erosivity factor (``R'' in RUSLE) is less 
    than five during the period of construction. For the purposes of 
    calculating this waiver, the period of construction activity starts at 
    the time of initial disturbance and ends with the time of final 
    stabilization. The operator must submit a written certification to the 
    Director in order to apply for such a waiver. EPA believes that those 
    areas receiving negligible rainfall during certain times of the year 
    are unlikely to have storm events causing discharges that could 
    adversely impact receiving streams. Consequently, BMPs would not be 
    necessary on those smaller sites. This waiver is most applicable to 
    projects of short duration and to the arid regions of the country where 
    the occurrence of rainfall follows a cyclic pattern--between no rain 
    and extremely heavy rain. EPA review of rainfall records for these 
    areas indicates that, during periods of the year when the number of 
    events and quantity of rain are low, storm water discharges from the 
    smaller construction sites regulated under today's rule should be 
    minimal.
        Some commenters supported the use of the R factor as a waiver, 
    while others felt that a waiver based on rainfall statistics ignores 
    the fact that it may rain on any given day and it is the cumulative 
    effect of wet weather discharges which cause water quality impairments. 
    A commenter also asked what happens in ``El Nino'' years when 
    significantly more rainfall than normal occurs. Another commenter also 
    expressed concern that this waiver was not based on a measured water 
    quality impact, but instead on an indicator of potential impact. In 
    response to the previous comments, EPA notes that, under CWA 402(p)(6), 
    sources are designated on their potential for adverse impact. 
    Designation under the section is prospective, not retrospective or 
    remedial only. For that reason, the waivers under today's rule also 
    operate prospectively. EPA wanted to waive requirements for sites with 
    little
    
    [[Page 68776]]
    
    potential to impair water quality, and the R factor is the most 
    straightforward way to do this. The permitting authority, if electing 
    to use waivers, could always suspend the use of waivers in certain 
    areas or during certain times. In addition, the permitting authority 
    may choose to use a lower R factor threshold than the one set by EPA. 
    Application of this waiver is at the discretion of the permitting 
    authority, subject only to the limitation that R factors cannot exceed 
    5.
        One commenter expressed the need for EPA to provide a justification 
    for the threshold value used for the R factor. None of the commenters 
    included any data to show that EPA's proposed R factor of 2 was either 
    too high or too low. EPA is using the R factor as an indicator of the 
    potential to impact water quality. In an effort to determine which R 
    threshold should be used, EPA conducted additional analysis of the 
    rainfall/runoff erosivity factor for 134 sites across the country. For 
    an R factor threshold of 5, approximately 12% of sites would be waived 
    if the project period lasted 6 months, 27% for 3 months, 47% for 1 
    month, and 60% of sites would be waived if the project lasted for only 
    15 days. None of the 134 sites would be waived if the project lasted an 
    entire year. For an R factor threshold of 2, approximately 9% of sites 
    would be waived if the project period lasted 6 months, 15% for 3 
    months, 31% for 1 month, and 43% for 15 days. For an R factor threshold 
    of 10, approximately 22% of sites would be waived if the project period 
    lasted 6 months, 37% for 3 months, 60% for 1 month, and 78% for 15 
    days. EPA believes that an R factor of 5 is an adequate threshold to 
    waive requirements for sites because they would not reasonably be 
    expected to impair water quality.
        EPA will develop, as part of the tool box described in section 
    II.A.5, guidance materials and computer or web-accessible programs to 
    assist permitting authorities and construction site discharges in 
    determining if any resulting storm water discharges from specific 
    projects are eligible for this waiver.
        ii. Water Quality Waiver. The water quality waiver under 
    Sec. 122.26(b)(15)(i)(B) is available where storm water controls are 
    not needed based on a comprehensive, location-specific evaluation of 
    water quality needs. The waiver is available based on either an EPA-
    approved ``total maximum daily load'' (TMDL) under section 303(d) of 
    the CWA that addresses the pollutant(s) of concern or, for sites 
    discharging to non-impaired waters that do not require TMDLs, an 
    equivalent analysis that has either determined allocations for small 
    construction sites for the pollutant(s) of concern or determined that 
    such allocations are not needed to protect water quality based on 
    consideration of existing in-stream concentrations, expected growth in 
    pollutant contributions from all sources, and a margin of safety. The 
    pollutants of concern that must be addressed include sediment or a 
    parameter that addresses sediment (such as total suspended solids 
    (TSS), turbidity or siltation) and any other pollutant that has been 
    identified as a cause of impairment of any water body that will receive 
    a discharge from the construction activity. The operator must certify 
    to the NPDES permitting authority that the construction activity will 
    take place, and storm water discharges will occur, within the 
    applicable drainage area evaluated in the TMDLs or equivalent analyses.
        Today's rule modifies the approach in the proposed rule. EPA 
    proposed to allow a waiver of permit requirements for small 
    construction if storm water controls were determined to be unnecessary 
    based on ``wasteload allocations that are part of `total maximum daily 
    loads' (TMDLs) that address the pollutants of concern,'' or ``a 
    comprehensive watershed plan, implemented for the water body, that 
    includes the equivalents of TMDLs, and addresses the pollutants of 
    concern.''
        Commenters asked for clarification of the terms ``comprehensive 
    watershed plans'' and ``equivalent of TMDLs.'' EPA intended that both 
    terms would include a comprehensive analysis that determines that 
    controls on small construction sites are not needed based on 
    consideration of existing in-stream concentrations, expected growth in 
    pollutant contributions from all sources, and a margin of safety. 
    Today's rule makes this clarification.
        One commenter pointed out that there are no water quality standards 
    for suspended solids, the major pollutant expected in discharges from 
    construction activity. The commenter asserted that no waiver would ever 
    be available. Another commenter noted that there are no sediment 
    criteria developed for streams, also making this waiver useless. EPA 
    notes that a number of States and Tribes have water quality standards 
    that address TSS, which are narrative in form, and that may serve as a 
    basis for water quality-based effluent limits. As efforts to identify 
    impairments and improve water quality progress, some States may yet 
    develop water quality standards for suspended solids. Although several 
    TMDLs for sediment and related parameters have been established, EPA 
    does recognize that currently it is extremely difficult to develop 
    TMDLs for sediment. EPA is partially addressing this concern by 
    clarifying in today's rule that the waivers may be based on a TMDL or 
    equivalent analyses for sediment or one of the various pollutant 
    parameters that are a proxy for sediment. These include TSS, turbidity 
    and siltation.
        Other commenters noted that this waiver was unattainable if a TMDL 
    or equivalent analysis must be available for every pollutant that could 
    possibly be present in any amount in discharges from small construction 
    sites regardless of whether the pollutant is causing water quality 
    impairment. Commenters asked that EPA identify what constitutes the 
    ``pollutants of concern'' for which a TMDL or its equivalent must be 
    developed. EPA has revised the proposed rule in response to these 
    concerns.
        In order for discharges from construction sites under five acres to 
    qualify for the water quality waiver of today's rule, the construction 
    site operator must demonstrate that storm water controls are not 
    necessary for sediment or a parameter that addresses sediment (such as 
    TSS, turbidity or siltation) and any other pollutant that has been 
    identified as a cause of impairment of any water body that will receive 
    a discharge from the construction activity. Even if the water body is 
    not currently impaired for sediment, today's rule requires an analysis 
    of the potential impacts of sediment because the storm water discharges 
    from the construction activity will be a new source of loading to the 
    water body that could constitute a new impairment. Because the water 
    body will not necessarily have been included on a ``303(d) list'' and a 
    TMDL will not necessarily be required, the rule continues to allow an 
    analysis that is the equivalent of a TMDL. The designation of storm 
    water discharges from small construction activity for regulation in 
    today's rule is intended to control pollutants other than sediment. 
    This waiver provision requires a TMDL or equivalent analysis for a 
    pollutant other than gross particulates (i.e., sediment and other 
    particulate-focused pollutant parameters) only if the receiving water 
    is currently impaired for that pollutant.
        One commenter expressed the concern that construction operators 
    will not know if they are in a watershed covered by a TMDL. To the 
    extent this is an operator's concern, he or she could contact their 
    NPDES permitting
    
    [[Page 68777]]
    
    authority before applying for permit coverage to determine if receiving 
    water is subject to a TMDL. Alternatively, the permitting authority 
    could identify the TMDL (or equivalent analysis) areas in the general 
    permit or another operator-accessible information source.
        Another commenter expressed the concern that a TMDL waiver is 
    likely to be ineffective because the TMDL list is submitted only once 
    every 2 years. By the time a water is listed, the activity may have 
    been completed and stabilized. The commenter argued that, if a 
    watershed is impaired due to sediment from construction, then storm 
    water controls will still be needed, because small construction can 
    only be waived when it is not identified as a source of impairment. In 
    response, EPA notes that an analysis that is the equivalent of a TMDL 
    (specifically, equivalent to the component of a TMDL that 
    comprehensively analyses existing ambient conditions against the 
    applicable water quality standards) may also provide a basis for waiver 
    from the default 1 acre designation. Also, even if a water has been 
    identified as impaired for sediment, it is possible that a site or 
    category of sites may receive an allocation that is sufficiently high 
    enough to allow discharges without storm water controls.
    c. Permit Process and Administration
        The operator of the construction site, as with any operator of a 
    point source discharge, is responsible for obtaining coverage under a 
    NPDES permit as required by Sec. 122.21(b). The ``operator'' of the 
    construction site, as explained in the current NPDES construction 
    general permit, is typically the party or parties that either 
    individually or collectively meet the following two criteria: (1) 
    Operational control over the site specifications, including the ability 
    to make modifications in the specifications; and (2) day-to-day 
    operational control of those activities at the site necessary to ensure 
    compliance with permit conditions (63 FR 7859). If more than one party 
    meets these criteria, then each party involved would typically be a co-
    permittee with any other operators. The operator could be the owner, 
    the developer, the general contractor, or individual contractor. When 
    responsibility for operational control is shared, all operators must 
    apply.
        In today's rule, EPA is not requiring an NOI for NPDES general 
    permits for storm water discharges from construction activities 
    regulated by Sec. 122.26(b)(15) if the NPDES permitting authority finds 
    that the use of NOIs would be inappropriate (see Sec. 122.28(b)(2)(v)). 
    Under this approach, the NPDES permitting authority will have the 
    discretion to decide whether or not to require NOIs for discharges from 
    construction activity less than 5 acres. Compared to the existing storm 
    water regulation, the permitting authority thus has increased 
    flexibility in program implementation. EPA does recommend the use of 
    NOIs, however because NOIs track permit coverage and provide a useful 
    information source to prioritize inspections or enforcement. Requiring 
    an NOI allows for greater accountability by, and tracking of, 
    dischargers. This simple permit application and reporting mechanism 
    also allows for better outreach to the regulated community, uses an 
    existing and familiar mechanism, and is consistent with the existing 
    requirements for storm water discharges from larger construction 
    activities. Today's rule does not amend the requirement for NOIs in 
    general permits for storm water discharges from construction activity 
    disturbing 5 acres for more. See Sec. 122.28(b)(2)(v).
        EPA expects that the vast majority of discharges of storm water 
    associated with small construction activity identified in 
    Sec. 122.26(b)(15) will be regulated through general permits. In the 
    event that an NPDES permitting authority decides to issue an individual 
    construction permit, however, individual application requirements for 
    these construction site discharges are found at Sec. 122.26(c)(1)(ii). 
    For any discharges of storm water associated with small construction 
    activity identified in Sec. 122.26(b)(15) that are not authorized by a 
    general permit, a permit application made pursuant to Sec. 122.26(c) 
    must be submitted to the Director by 3 years and 90 days after 
    publication of the final rule.
        Some commenters expressed concern that linear construction projects 
    (e.g., roads, highways, pipelines) that cross several jurisdictions 
    will have to comply with multiple sets of requirements from various 
    jurisdictions, including multiple local governments and States. EPA is 
    limited in its options to address these concerns because the Agency 
    cannot issue NPDES permits in States authorized to implement the NPDES 
    program nor preempt other more stringent local and State requirements. 
    EPA believes, however, that the option for incorporating by reference 
    the State, Tribal or local requirements (see discussion in Section 
    II.I.2.d., Cross-Referencing State/Local Erosion and Sediment Control 
    Programs) should limit the administrative burden on the operator 
    responsible for discharges from linear construction projects. If the 
    operator were to implement the most comprehensive of the various 
    requirements for the whole project, it could avoid confusion due to 
    differing requirements for different sections of the project. In 
    addition, linear utility projects, which usually have a shorter project 
    period, are more likely to be eligible for the rainfall erosivity 
    waiver.
        One commenter stated there was no reason to delay the application 
    period for regulated storm water discharges from small construction 
    activities. The commenter requested that the newly regulated 
    construction site discharges should be required to seek permit coverage 
    within 90 days, as opposed to 3 years, of the effective date of the 
    rule. The Agency does not accept this request. EPA anticipates that 
    NPDES permitting authorities will need one to two years to develop 
    adequate legal authority to implement a program to address this new 
    category of discharges, as well as to develop and issue general 
    permits. Moreover, to ensure effective implementation to protect water 
    quality, regulatory authorities will need additional time to inform 
    small construction site operators of requirements and provide guidance 
    and training on these requirements.
        Finally, EPA received a comment requesting that the three year file 
    retention requirement be deleted for discharges from small construction 
    sites. While EPA recognizes that the three year record retention 
    schedule may be unnecessary for certain construction projects, the 
    Agency has determined it is necessary to retain files after the 
    completion of the project to ensure permit compliance, including 
    applicable construction site stabilization enabling permit termination 
    for such sites.
    d. Cross-Referencing State, Tribal or Local Erosion and Sediment 
    Control Programs
        In developing the NPDES permit requirements for construction sites 
    less than 5 acres, members of the Storm Water Phase II FACA 
    Subcommittee asked EPA to try to minimize redundancy in the 
    construction permit requirements. In response, today's rule at 
    Sec. 122.44(s) provides for incorporation of qualifying State, Tribal 
    or local erosion and sediment control program requirements by reference 
    into the NPDES permit authorizing storm water discharges from 
    construction sites (described under Secs. 122.26(b)(15) and 
    (b)(14)(x)). The incorporation by reference approach applies not only 
    to the newly regulated storm water discharges (from construction 
    activity disturbing between 1 and 5 acres, including designated sites, 
    but
    
    [[Page 68778]]
    
    excluding waived sites) but also to discharges from construction 
    activity disturbing 5 or more acres already covered by the existing 
    storm water regulations. For this latter category of discharges from 
    construction activity disturbing 5 or more acres, the incorporation by 
    reference approach requires that the pollutant control requirements 
    from the incorporated program also satisfy the statutory standard for 
    limitations representing application of the best available technology 
    economically achievable (BAT) and best conventional pollutant control 
    technology (BCT).
        For permits issued for discharges from small construction activity 
    defined under Sec. 122.26(b)(15), a qualifying State, Tribal, or local 
    erosion and sediment control program is one that includes the program 
    elements described under Sec. 122.44(s)(1). These elements include 
    requirements for construction site operators to implement appropriate 
    erosion and sediment control BMPs, requirements to control waste, a 
    requirement to develop a storm water pollution prevention plan, and 
    requirements to submit a site plan for review. A storm water pollution 
    prevention plan includes site descriptions, descriptions of appropriate 
    control measures, copies of approved State, Tribal or local 
    requirements, maintenance procedures, inspection procedures, and 
    identification of non-storm water discharges. The construction site's 
    permit would require it to follow the requirements of the qualifying 
    local program rather than require it to follow two different sets of 
    requirements. If a partially-qualifying program does not have all of 
    the elements described under Sec. 122.44(s)(1), then the NPDES 
    permitting authority may still incorporate language in the small 
    construction site discharge's permit that requires the construction 
    site operator to follow the program, but the construction site 
    discharge permit also must incorporate the missing required elements in 
    order to satisfy CWA requirements.
        The term ``local'' refers to the geographic area of applicability, 
    not the form of government that develops and administers the program. 
    Thus, a qualifying federal erosion and control program, such as certain 
    programs developed and administered by the federal Bureau of Land 
    Management, could be a qualifying local program.
        As a result of this provision, local requirements will, in effect, 
    provide the substantive construction site erosion and sediment control 
    requirements for the NPDES permit authorization. Therefore, by 
    following one set of erosion and sediment control requirements, 
    construction site operators satisfy both local and NPDES permit 
    requirements without duplicative effort. At the same time, 
    noncompliance with the referenced local requirements will be considered 
    noncompliance with the NPDES permit which is federally enforceable. The 
    NPDES permitting authority will, of course, retain the discretion to 
    decide whether to include the alternative requirements in the general 
    permit. EPA believes that this approach will best balance the need for 
    consideration of specific local requirements and local implementation 
    with the need for federal and citizen oversight, and will extend 
    supplemental NPDES requirements to control storm water discharges from 
    construction sites.
        EPA developed the ``incorporation by reference'' approach based on 
    implementation efforts designed by the State of Michigan. Michigan 
    relies on localities to develop substantive controls for storm water 
    discharges associated with construction activities on a localized 
    basis. Localities, however, are not required to do so. In areas where 
    the local authority does not choose to participate, the State 
    administers the sedimentation and erosion control requirements. The 
    State agency, as the NPDES permitting authority, receives an NOI 
    (termed ``notice of coverage'' by Michigan) under the general permit 
    and tracks and exercises oversight, as appropriate, over the activity 
    causing the storm water discharge. Michigan's goal under these 
    procedures is to utilize the existing erosion and sediment control 
    program infrastructure authorized under State law for storm water 
    discharge regulation. (See U.S. Environmental Protection Agency, Office 
    of Water. January 7, 1994. Memo: From Michael B. Cook, Director OWEC, 
    to Water Management Division Directors, Regarding the ``Approach Taken 
    by Michigan to Regulate Storm Water Discharges from Construction 
    Activities.'')
        Most commenters supported the general concept of incorporating by 
    reference qualifying programs. Two commenters expressed concern that 
    different local construction requirements will create an impossible 
    regulatory scheme for builders who work in different localities. EPA 
    believes that allowing States to incorporate qualifying programs by 
    reference will minimize the differences for builders who work in 
    different areas of the State. These differences already exist, however, 
    not only for erosion and sediment controls, but also other aspects of 
    construction. In any event, the criteria for qualification for 
    localized programs should provide a certain degree of standardization 
    for various localities' requirements. EPA expects that the new rule for 
    construction and post-construction BMPs being developed under CWA 
    section 304(m) will also encourage standardization of local 
    requirements. (See discussion of this new rulemaking in section II.D.1, 
    Federal Role of this preamble).
        Two commenters requested that an ``incorporation by reference'' 
    should include permission, in writing, from the qualifying local 
    program administrator because of a perceived extra burden on the 
    referenced program. Any program requirements incorporated by reference 
    in NPDES permits should already apply to construction site dischargers 
    in the applicable area and therefore should not add any additional 
    burden to the referenced program. EPA has left to the discretion of the 
    permitting authority the decision on whether to seek permission from 
    the qualifying program before cross-referencing it in an NPDES permit.
        One commenter stated that a qualifying local program should require 
    a SWPPP. The proposed rule defined the qualifying local program as a 
    program the meets the minimum program requirements established in the 
    proposed construction minimum control measure for small MS4s. To ensure 
    consistency in the controls for storm water discharges between the 
    larger, already regulated construction sites and the discharges from 
    smaller sites that will be regulated as a result of today's rule, EPA 
    has made a change to define a qualifying local program as one that 
    includes the elements described in Sec. 122.44(s)(1). Section 
    122.44(s)(1) requires the development and implementation of a storm 
    water pollution prevention plan as a criterion for qualification of 
    local programs for incorporation by reference. As noted above, if a 
    qualifying program does not include all the elements in 
    Sec. 122.44(s)(1) then the permitting authority will need to specify 
    the missing elements in order to rely on the incorporation by reference 
    approach.
        One commenter asked what happens in regard to the use of qualifying 
    programs when a construction site operator is also the qualifying local 
    program operator. The provision for incorporation by reference applies 
    in this situation also. The local program operator will be required to 
    comply with requirements it has established for others.

    e. Alternative Approaches
        EPA received a number of comments on alternative permitting 
    approaches. Several commenters supported regulating discharges only 
    from those construction sites within urbanized areas. Other commenters 
    opposed this approach. EPA chose to address storm water discharges from 
    construction sites located both within and outside urbanized areas 
    because of the potential for adverse water quality impact from storm 
    water discharges from smaller sites in all areas. Regulating only those 
    sites within urbanized areas would have excluded a large number of 
    potential contributors to water quality impairment and would not 
    address large areas of new development occurring on the outer fringes 
    of urbanized areas. In fact, designating only small construction 
    discharges within urbanized areas might create a perverse incentive for 
    building only outside urbanized areas. Such an incentive would be 
    inconsistent with the Agency's intention behind designating to protect 
    water quality. The Agency intends that designation to protect water 
    quality in today's rule should be both remedial and preventive.
        A number of commenters encouraged EPA to cover municipal 
    construction activities under the small MS4 general permit, instead of 
    issuing a separate NPDES construction permit to these municipal 
    construction projects. Similarly, a number of commenters supported EPA 
    giving industrial facilities the option of having storm water from 
    construction activities on the site covered by the industrial storm 
    water permit. Several other commenters found that combining multiple 
    permit types under one general permit introduced a degree of complexity 
    which was confusing to permittees. Permitting authorities have the 
    option of combining MS4 and construction permits or industrial and 
    construction permits, however, specific requirements for each would 
    still need to be included in the permit issued. EPA agrees that this 
    would probably result in a more complex and confusing permit compared 
    to the existing component permits.
        Several commenters supported an alternative for regulated small 
    MS4s where a local qualified program alone, without an NPDES permit, is 
    sufficient to enforce compliance with construction site discharge 
    requirements. On the other hand, one commenter stated that linking the 
    local construction erosion and sediment control program to the existing 
    NPDES program for storm water from larger construction has driven 
    improvements in many local programs. Another commenter stated that the 
    potential fines under the NPDES program will encourage compliance and 
    will be much stronger than any fines a local program may have. EPA 
    agrees that the NPDES program is the best approach to address water 
    quality impacts from construction sites and provides benefits such as 
    accountability and federal enforcement.
        A number of commenters supported issuing one permit for each 
    construction company, instead of a permit for each individual 
    construction activity (also requested for storm water discharges from 
    the larger, already regulated construction sites). Other commenters 
    found that a `licensing' program for construction site operators would 
    have many problems, including identifying who to permit and tracking 
    information on active sites. EPA is regulating only the storm water 
    discharges associated with construction activity from small sites, not 
    the construction activity itself. Separate NPDES permits (either 
    individual or general permit coverage) for construction site discharges 
    avoid potential problems in tracking sites and operator accountability. 
    Section 122.28(b)(2)(v) gives permitting authorities the option to 
    issue a general permit without requiring an NOI. If an NOI is not 
    required for each activity, permitting authorities could pursue other 
    options such as a company-wide NOI, license instead of an NOI, or 
    another mechanism.
    2. Other Sources
        In the Storm Water Discharges Potentially Addressed by Phase II of 
    the National Pollutant Discharge Elimination System Storm Water 
    Program, Report to Congress, March 1995, (``Report'') submitted by EPA 
    pursuant to CWA section 402(p)(5), EPA examined the remaining 
    unregulated point sources of storm water for the potential to adversely 
    affect water quality. Due to very limited national data on which to 
    estimate pollutant loadings on the basis of discharge categories, the 
    discussion of the extent of unregulated storm water discharges is 
    limited to an analysis of the number and geographic distribution of the 
    unregulated storm water discharges. Therefore, EPA is not designating 
    any additional unregulated point sources of storm water on a 
    nationwide, categorical basis. Instead, the remainder of the sources 
    will be regulated based on case-by-case post-promulgation designations 
    by the NPDES permitting authority.
        EPA did, however, evaluate a variety of categories of discharges 
    for potential designation in the Report. EPA's efforts to identify 
    sources and categories of unregulated storm water discharges for 
    potential designation for regulation in today's rule started with an 
    examination of approximately 7.7 million commercial, retail, 
    industrial, and institutional facilities identified as ``unregulated.'' 
    In general, the distribution of these facilities follows the 
    distribution of population, with a large percentage of facilities 
    concentrated within urbanized areas (see page 4-35 of the Report). This 
    examination resulted in identification of two general classes of 
    facilities with the potential for discharging pollutants to waters of 
    the United States through storm water point sources.
        The first group (Group A) included sources that are very similar, 
    or identical, to regulated ``storm water discharges associated with 
    industrial activity'' but that were not included in the existing storm 
    water regulations because EPA used SIC codes in defining the universe 
    of regulated industrial activities. By relying on SIC codes, a 
    classification system created to identify industries rather than 
    environmental impacts from these industries discharges, some types of 
    storm water discharges that might otherwise be considered 
    ``industrial'' were not included in the existing NPDES storm water 
    program. The second general class of facilities (Group B) was 
    identified on the basis of potential for activities and pollutants that 
    could contribute to storm water contamination.
        EPA estimates that Group A has approximately 100,000 facilities. 
    Discharges from facilities in this group, which may be of high priority 
    due to their similarity to regulated storm water discharges from 
    industrial facilities, include, for example, auxiliary facilities or 
    secondary activities (e.g., maintenance of construction equipment and 
    vehicles, local trucking for an unregulated facility such as a grocery 
    store) and facilities intentionally omitted from existing storm water 
    regulations (e.g., publicly owned treatment works with a design flow of 
    less than 1 million gallons per day, landfills that have not received 
    industrial waste).
        Group B consists of nearly one million facilities. EPA organized 
    Group B sources into 18 sectors for the purposes of the Report. The 
    automobile service sector (e.g., gas/service stations, general 
    automobile repair, new and used car dealerships, car and truck rental) 
    makes up more than one-third of the total number of facilities 
    identified in all 18 sectors.
        EPA conducted a geographical analysis of the industrial and 
    commercial facilities in Groups A and
    
    [[Page 68780]]
    
    B. The geographical analysis shows that the majority are located in 
    urbanized areas (see Section 4.2.2, Geographic Extent of Facilities, in 
    the Report). In general, about 61 percent of Group A facilities and 56 
    percent of Group B facilities are located in urbanized areas. The 
    analysis also showed that nearly twice as many industrial facilities 
    are found in all urbanized areas as are found in large and medium 
    municipalities alone. Notable exceptions to this generalization 
    included lawn/garden establishments, small unregulated animal feedlots, 
    wholesale livestock, farm and garden machinery repair, bulk petroleum 
    wholesale, farm supplies, lumber and building materials, agricultural 
    chemical dealers, and petroleum pipelines, which can frequently be 
    located in smaller municipalities or rural areas.
        In identifying potential categories of sources for designation in 
    today's notice, EPA considered designation of discharges from Group A 
    and Group B facilities. EPA applied three criteria to each potential 
    category in both groups to determine the need for designation: (1) The 
    likelihood for exposure of pollutant sources included in that category, 
    (2) whether such sources were adequately addressed by other 
    environmental programs, and (3) whether sufficient data were available 
    at this time on which to make a determination of potential adverse 
    water quality impacts for the category of sources. As discussed 
    previously, EPA searched for applicable nationwide data on the water 
    quality impacts of such categories of facilities.
        By application of the first criterion, the likelihood for exposure, 
    EPA considered the nature of potential pollutant sources in exposed 
    portions of such sites. As precipitation contacts industrial materials 
    or activities, the resultant runoff is likely to mobilize and become 
    contaminated by pollutants. As the size of these exposed areas 
    increases, EPA expects a proportional increase in the pollutant 
    loadings leaving the site. If EPA concluded that a category of sources 
    has a high potential for exposure of raw materials, intermediate 
    products, final products, waste materials, byproducts, industrial 
    machinery, or industrial activity to rainfall, the Agency rated that 
    category of sources as having ``high'' potential for adverse water 
    quality impact. EPA's application of the first criterion showed that a 
    number of Group A and B sources have a high likelihood of exposure of 
    pollutants.
        Through application of the second criterion, EPA assessed the 
    likelihood that pollutant sources are regulated in a comprehensive 
    fashion under other environmental protection programs, such as programs 
    under the Resource Conservation and Recovery Act (RCRA) or the 
    Occupational Health and Safety Act (OSHA). If EPA concluded that the 
    category of sources was sufficiently addressed under another program, 
    the Agency rated that source category as having ``low'' potential for 
    adverse water quality impact. Application of the second criterion 
    showed that some categories were likely to be adequately addressed by 
    other programs.
        After application of the third criterion, availability of 
    nationwide data on the various storm water discharge categories, EPA 
    concluded that available data would not support any such nationwide 
    designations. While such data could exist on a regional or local basis, 
    EPA believes that permitting authorities should have flexibility to 
    regulate only those categories of sources contributing to localized 
    water quality impairments.
        EPA received comments requesting designation of additional 
    industrial, commercial and retail sources (e.g. industrial activity 
    ``look-alikes'', roads, commercial facilities and institutions, and 
    vehicle maintenance facilities) in the final rule, because the 
    commenters believe that the data exist to support national designation 
    of some of these sources. Other comments were received opposing 
    designation of any additional sources. Today's rule does not designate 
    any additional industrial or commercial category of sources either 
    because EPA currently lacks information indicating a consistent 
    potential for adverse water quality impact or because of EPA's belief 
    that the likelihood of adverse impacts on water quality is low, with 
    some possible exceptions on a more local basis. Since the time the 
    Agency submitted the Report, EPA has continued to seek additional data 
    and has requested available data from the FACA members. If sufficient 
    regional or nationwide data become available in the future, the 
    permitting authority could at that time designate a category of sources 
    or individual sources on a case-by-case basis. Therefore, today's rule 
    encourages control of storm water discharges from Groups A and B 
    through self-initiated, voluntary BMPs, unless the discharge (or 
    category of discharges) is designated for permitting by the permitting 
    authority. See discussion in section I.D., EPA's Reports to Congress.
    3. ISTEA Sources
        Provisions within the Intermodal Surface Transportation and 
    Efficiency Act (ISTEA) of 1991 temporarily exempted storm water 
    discharges associated with industrial activity that are owned or 
    operated by municipalities serving populations less than 100,000 people 
    (except for airports, power plants, and uncontrolled sanitary 
    landfills) from the need to apply for or obtain a storm water discharge 
    permit (section 1068(c) of ISTEA). Congress extended the NPDES 
    permitting moratorium for these facilities to allow small 
    municipalities additional time to comply with NPDES requirements for 
    certain sources of industrial storm water. The August 7, 1995 storm 
    water final rule (60 FR 40230) further extended this moratorium until 
    August 7, 2001. However, today's rule changes this deadline so that 
    previously exempted industrial facilities owned or operated by 
    municipalities serving populations less than 100,000 people, must now 
    submit an application for a permit within 3 years and 90 days from date 
    of publication of today's rule.
        EPA received comments recommending that permit requirements for 
    municipally owned or operated industrial storm water discharges, 
    including those previously exempt under ISTEA, be included in a single 
    NPDES permit for all MS4 storm water discharges. The existing NPDES 
    regulations already provide permitting authorities the ability to issue 
    a single ``combination'' permit for MS4 discharges. However, if the 
    permitting authorities chose to issue this type of permit, they must 
    make sure that in doing so, they are not creating a double standard for 
    industrial facilities covered under the combination permit versus those 
    covered under separate general or individual permits. In order to avoid 
    this double standard, combination permits would have to contain 
    requirements that are the same or very similar to the requirements 
    found in separate MS4 and industrial permits, i.e., the minimum 
    measures and other necessary requirements of an MS4 permit, and the 
    SWPPP, monitoring and reporting requirements, and other necessary 
    requirements of an industrial permit. If such a combined MS4 general 
    permit were issued, the regulations require that each discharger submit 
    NOIs for their respective discharges, except for discharges from small 
    construction activities. Flexibility exists in developing a combination 
    NOI which could reduce the need to submit duplicative information, e.g. 
    owner/operator name and address. The combination NOI would still need 
    to require specific information for each separate municipally owned or 
    operated industrial location, including
    
    [[Page 68781]]
    
    construction projects disturbing 5 or more acres. The regulations at 
    Sec. 122.28(b)(2)(ii) list the necessary contents of an NOI, which 
    require: the facility name, facility address, type of facility or 
    discharge and receiving stream for each industrial discharge location. 
    When viewed in its entirety, a combination permit, which by necessity 
    would need to contain all elements of otherwise separate industrial and 
    MS4 permit requirements, and require NOI information for each separate 
    industrial activity, may have few advantages when compared to obtaining 
    separate MS4 and industrial general permit coverage.
        In order to allow the permitting authority to issue a single storm 
    water permit for the MS4 and all municipally owned or operated 
    industrial facilities, including those previously exempt under ISTEA, 
    today's rule requires applications for ISTEA sources within 3 yrs and 
    90 days from date of publication of today's rule. The permitting 
    authority has the ultimate decision to determine whether or not a 
    single all-encompassing MS4 permit is appropriate.
    4. Residual Designation Authority
        The NPDES permitting authority's existing designation authority, as 
    well as the petition provisions are being retained. Today's rule 
    contains two provisions related to designation authority at 
    Secs. 122.26(a)(9)(i)(C) and (D). Subsection (C) adds designation 
    authority where storm water controls are needed for the discharge based 
    upon wasteload allocations that are part of TMDLs that address the 
    pollutant(s) of concern. EPA intends that the NPDES permitting 
    authority have discretion in the matter of designations based on TMDLs 
    under subsection (C). Subsection (D) carries forward residual 
    designation authority under former Sec. 122.26(g), and has been 
    modified to provide clarification on categorical designation. Under 
    today's rule, EPA and authorized States continue to exercise the 
    authority to designate remaining unregulated discharges composed 
    entirely of storm water for regulation on a case-by-case basis 
    (including Sec. 123.35). Individual sources are subject to regulation 
    if EPA or the State, as the case may be, determines that the storm 
    water discharge from the source contributes to a violation of a water 
    quality standard or is a significant contributor of pollutants to 
    waters of the United States. This standard is based on the text of 
    section CWA 402(p). In today's rule, EPA believes, as Congress did in 
    drafting section CWA 402(p)(2)(E), that individual instances of storm 
    water discharge might warrant special regulatory attention, but do not 
    fall neatly into a discrete, predetermined category. Today's rule 
    preserves the regulatory authority to subsequently address a source (or 
    category of sources) of storm water discharges of concern on a 
    localized or regional basis. For example, as States and EPA implement 
    TMDLs, permitting authorities may need to designate some point source 
    discharges of storm water on a categorical basis either locally or 
    regionally in order to assure progress toward compliance with water 
    quality standards in the watershed.
        EPA received comments asking that Sec. 122.26(a)(9)(i)(D) as 
    proposed be modified to include specific language clarifying the 
    permitting authority's ability to designate additional sources on a 
    categorical basis as explained in the preamble to the proposed rule. 
    One comment requested that the designation language include 
    ``categories of sources on a Statewide basis.'' EPA agrees that the 
    intent of the language may not have been clear regarding categorical 
    designation. Today's rule modifies subsection (D) to clarify that the 
    designation authority can be applied within different geographic areas 
    to any single discharge (i.e., a specific facility), or category of 
    discharges that are contributing to a violation of a water quality 
    standard or are significant contributors of pollutants to waters of the 
    United States. The added term ``within a geographic area'' allows 
    ``State-wide'' or ``watershed-wide'' designation within the meaning of 
    the terms.
        One commenter questioned the Agency's legal authority to provide 
    for such residual designation authority. The stakeholder argued that 
    the lapse of the October 1, 1994, permitting moratorium under CWA 
    section 402(p)(1) eliminated the significance of the CWA section 
    402(p)(2) exceptions to the moratorium, including the exception for 
    discharges of storm water determined to be contributing to a violation 
    of a water quality standard or a significant contributor of pollutants 
    under CWA section 402(p)(2)(E). The stakeholder further argued that 
    EPA's authority to designate sources for regulation under CWA section 
    402(p)(6) is limited to storm water discharges other than those 
    described under CWA section 402(p)(2). Because CWA section 402(p)(2)(E) 
    describes individually designated discharges, the stakeholder concluded 
    that regulations under CWA section 402(p)(6) cannot provide for post-
    promulgation designation of individual sources. EPA disagrees.
        First, as explained previously, EPA anticipates that NPDES 
    permitting authorities may yet determine that individual unregulated 
    point sources of storm water discharges require regulation on a case-
    by-case basis. This conclusion is consistent with the Congress' 
    recognition of the potential need for such designation under the first 
    phase of storm water regulation as described in CWA section 
    402(p)(2)(E). Under CWA section 402(p)(2)(E), Congress recognized the 
    need for both EPA and the State to retain authority to regulate 
    unregulated point sources of storm water under the NPDES permit 
    program. Second, to the extent that CWA section 402(p)(6) requires 
    designation of a ``category'' of sources, the permitting authority may 
    designate such (as yet unidentified) sources as a category that should 
    be regulated to protect water quality. Though such sources may exist 
    and discharge today, if neither EPA nor the State/Tribal NPDES 
    permitting authority has designated the source for regulation under CWA 
    section 402(p)(2)(E) to date, then CWA section 402(p)(6) provides the 
    authority to designate such sources.
        The Agency can designate a category of ``not yet identified'' 
    sources to be regulated, based on local concerns, even if data do not 
    exist to support nationwide regulation of such sources. EPA does not 
    interpret the language in CWA section 402(p) to preclude States from 
    exercising designation authority under these provisions because such 
    designation (and subsequent regulation of designated sources) is within 
    the ``scope'' of the NPDES program.
        EPA also believes that sources regulated pursuant to a State 
    designation are part of (and regulated under) a federally approved 
    State NPDES program, and thus subject to enforcement under CWA sections 
    309 and 505. Under existing NPDES State program regulations, State 
    programs that are ``greater in scope of coverage'' are not part of the 
    federally-approved program. By contrast, any such State regulation of 
    sources in this ``reserved category'' will be within the scope of the 
    federal program because today's rule recognizes the need for such post 
    promulgation designations of unregulated point sources of storm water. 
    Such regulation will be ``more stringent'' than the federal program 
    rather than ``greater in scope of coverage'' (40 CFR 123.1(h)).
        EPA does not interpret the congressional direction in CWA section 
    402(p)(6) to preclude regulation of point sources of storm water that 
    should be regulated to protect water quality. Under CWA section 510, 
    Congress expressly recognized and preserved the authority of States to 
    adopt and enforce
    
    [[Page 68782]]
    
    more stringent regulation of point sources, as well as any requirement 
    respecting the control or abatement of pollution. Section 510 applies, 
    ``except as expressly provided'' in the CWA. CWA section 502(14) does 
    expressly provide affirmative limitations on the regulation of certain 
    pollutant sources through the point source control program, the NPDES 
    permitting program. Section 502(14) excludes agricultural storm water 
    and return flows from irrigated agriculture from the definition of 
    point source, and section 402(l) limits applicability of the section 
    402 permit program for return flows from irrigated agriculture, as well 
    as for storm water runoff from certain oil, gas, and mining operations. 
    Unlike sections 502(14) and 402(l), EPA does not interpret CWA section 
    402(p)(6) as an express provision limiting the authority to designate 
    point sources of storm water for regulation on a case-by-case basis 
    after the promulgation of final regulations. Any source of storm water 
    discharge is encouraged to assess its potential for storm water 
    contamination and take preventive measures against contamination. Such 
    proactive actions could result in the avoidance of future regulation.
        One comment was received requesting clarification of the term 
    ``non-municipal'' in Sec. 122.26(a)(9)(ii). The commenter is concerned 
    that the term ``non-municipal,'' in this context, implies that 
    municipally owned or operated facilities cannot be designated. The term 
    ``non-municipal'' in this context refers to the universe of unregulated 
    industrial and commercial facilities that could potentially be 
    designated according to Sec. 122.26(a)(9)(i) authority. There is no 
    exemption for municipally owned or operated facilities under these 
    designation provisions.
        Finally, EPA received comments and evaluated the proposal under 
    which operators of regulated small, medium, and large MS4s would be 
    responsible for controlling discharges from industrial and other 
    facilities into their systems in lieu of requiring NPDES permit 
    coverage for such facilities. EPA did not adopt this framework due to 
    concerns with administrative and technical burden on the MS4 operators, 
    as well as concerns about such an intergovernmental mandate.
    
    J. Conditional Exclusion for ``No Exposure'' of Industrial Activities 
    and Materials to Storm Water
    
    1. Background
        In 1992, the Ninth Circuit court remanded to EPA for further 
    rulemaking, a portion of the definition of ``storm water discharge 
    associated with industrial activity'' that excluded the category of 
    industrial activity identified as ``light industry'' when industrial 
    materials and/or activities were not exposed to storm water. See NRDC 
    v. EPA, 966 F.2d 1292, 1305 (9th Cir. 1992). Today's final rule 
    responds to that remand. In the 1990 storm water regulations, EPA 
    excluded the light industry category from the requirement for an NPDES 
    permit if the industrial materials and/or activities were not 
    ``exposed'' to storm water (see Sec. 122.26(b)(14)). The Agency had 
    reasoned that most of the activity at these types of facilities takes 
    place indoors and that emissions from stacks, use of unhoused 
    manufacturing equipment, outside material storage or disposal, and 
    generation of large amounts of dust or particles would be atypical (55 
    FR 48008, November 16, 1990).
        The Ninth Circuit determined that the exemption was arbitrary and 
    capricious for two reasons. First, the court found that EPA had not 
    established a record to support its assumption that light industry that 
    was not exposed to storm water was not ``associated with industrial 
    activity,'' particularly when other types of industrial activity not 
    exposed to storm water remained ``associated with industrial 
    activity.'' The court specifically found that ``[t]o exempt these 
    industries from the normal permitting process based on an 
    unsubstantiated assumption about this group of facilities is arbitrary 
    and capricious.'' Second, the court concluded that the exemption 
    impermissibly ``altered the statutory scheme'' for permitting because 
    the exemption relied on the unverified judgment of the light industrial 
    facility operator to determine non-applicability of the permit 
    application requirements. In other words, the court was critical that 
    the operator would determine for itself that there was ``no exposure'' 
    and then simply not apply for a permit without any further action. 
    Without a basis for ensuring the effective operation of the permitting 
    scheme--either that facilities would self-report actual exposure or 
    that EPA would be required to inspect and monitor such facilities--the 
    court vacated and remanded the rule to EPA for further rulemaking.
        One of the major concerns expressed by the FACA Committee, was that 
    EPA streamline and reinvent certain troublesome or problematic aspects 
    of the existing permitting program for storm water discharges. One area 
    identified was the mandatory applicability of the permitting program to 
    all industrial facilities, even those ``light industrial'' activities 
    that are of very low risk or of no risk to storm water contamination. 
    Such dischargers may not have any industrial sources of storm water 
    contamination on the plant site, yet they are still required to apply 
    for an NPDES storm water permit and meet all permitting requirements. 
    Examples of such facilities are a soap manufacturing plant (SIC Code 
    28) or hazardous waste treatment and disposal facility, where all 
    industrial activities, even loading docks, are inside a building or 
    under a roof.
        Although they did not provide a written report, the FACA Committee 
    members advised EPA that the existing storm water program should be 
    revised to allow such facilities to seek an exclusion from the NPDES 
    storm water permitting requirements. The Committee agreed that such an 
    exclusion should also provide a strong incentive for other industrial 
    facilities that conduct industrial activities outdoors to move the 
    activities under cover or into buildings to prevent contamination of 
    rainfall and storm water runoff. The committee believed that such a 
    ``no exposure'' permit exclusion could be a valuable incentive for 
    storm water pollution prevention.
        In today's final rule, the Agency responds to both of the bases for 
    the court's remand. The exclusion from permitting based on ``no 
    exposure'' applies to all industrial categories listed in the existing 
    storm water regulations except construction. The court's opinion 
    rejected EPA's distinction between light industry and other industry, 
    but it did not preclude an interpretation that treats all ``non-
    exposed'' industrial facilities in the same fashion. Presuming that an 
    industrial facility adequately prevents exposure of industrial 
    materials and activities to storm water, today's rule treats discharges 
    from ``non-exposed'' industrial facilities in a manner similar to the 
    way Congress intended for discharges from administrative buildings and 
    parking lots. Specifically, permits will not be required for storm 
    water discharges from these facilities on a categorical basis.
        To assure that discharges from industrial facilities really are 
    similar to discharges from administrative buildings and parking lots, 
    and to respond to the second basis for the court's remand, the 
    permitting exclusion is ``conditional''. The person responsible for a 
    point source discharge from a ``no exposure'' industrial source must 
    meet the conditions of the exclusion, and complete, sign and submit the 
    certification to the permitting authority for tracking and
    
    [[Page 68783]]
    
    accountability purposes. EPA believes today's rule, therefore, is fully 
    consistent with the direction provided by the court.
        EPA relied upon the ``no exposure'' concept discussed by the FACA 
    Committee in developing the ``no exposure'' provisions of today's rule. 
    EPA is deleting the sentence regarding ``no exposure'' for the 
    facilities in Sec. 122.26(b)(14)(xi) and adding a new Sec. 122.26(g) 
    titled ``Conditional Exclusion for No Exposure of Industrial Activities 
    to Storm Water.'' The ``no exposure'' provision will make storm water 
    discharges from all classes of industrial facilities eligible for 
    exclusion, except storm water discharges from regulated construction 
    activities. Regulated construction activities cannot claim ``no 
    exposure'' because the main pollutants of concern (e.g., sediment) 
    generally cannot entirely be sheltered from storm water.
        Today's rule represents a significant expansion in the scope of the 
    ``no exposure'' provision originally promulgated in the 1990 rule, 
    which was only for storm water discharges from light industry. The 
    intent of today's ``no exposure'' provision is to provide a simplified 
    method for complying with the CWA to all industrial facilities that are 
    entirely indoors. This includes facilities that are located within a 
    large office building, or at which the only items permanently exposed 
    to precipitation are roofs, parking lots, vegetated areas, and other 
    non-industrial areas or activities.
        EPA received several comments related to storm water runoff from 
    parking lots, roof tops, lawns, and other non-industrial areas of an 
    industrial facility. Storm water discharges from these areas, which may 
    contain pollutants or which may result in additional storm water flows, 
    are not directly regulated under the existing storm water permitting 
    program because they are not ``storm water discharges associated with 
    industrial activity''. Many comments on this issue supported 
    maintaining the exclusion from the existing regulations for storm water 
    permitting for discharges from administrative buildings, parking lots, 
    and other non-industrial areas. Other comments opposed allowing the 
    continued exclusion for discharges from non-industrial areas of the 
    site because discharges from these areas are potentially a significant 
    cause of receiving water impairment. These comments urged that such 
    discharges should not be excluded from NPDES permit coverage. Today's 
    rule does not require permit coverage for discharges from a facility's 
    exposed areas that are separate from industrial activities such as 
    runoff from office buildings and accompanying parking lots, lawns and 
    other non-industrial areas. This approach is consistent with the 
    existing storm water rules which were based on Congress's intent to 
    exclude non-industrial areas such as ``parking lots and administrative 
    and employee buildings.'' 133 Cong. Rec. 985 (1987). EPA also lacks 
    data indicating that discharges from these areas at an industrial 
    facility cause significant receiving water impairments. Therefore, the 
    non-industrial areas at a facility do not need to be assessed as part 
    of the ``no exposure'' certification.
        EPA received comments related to industrial facilities that achieve 
    ``no exposure'' by constructing large amounts of impervious surfaces, 
    such as roofs, where previously there were pervious or porous surfaces 
    into which storm water could infiltrate. Some commenters made the point 
    that large amounts of impervious area may cause a significant increase 
    in storm water volume flowing off the industrial facility, and thus may 
    cause adverse receiving water impacts simply due to the increased 
    quantity of storm water flow. Some commenters said that storm water 
    discharges from impervious areas at an industrial facility are 
    generally more frequent, and often larger, than discharges from the 
    pre-existing natural surfaces. They believe that these discharges will 
    contain pollutants typical of commercial areas and roads and are an 
    equal threat to direct human uses of the water and can cause equal 
    damage to aquatic life and its habitat. Other commenters believe that 
    if Congress or EPA addresses the issue of flow, it should be addressed 
    on a broader scale than merely through the ``no exposure'' exclusion, 
    and that EPA has no authority under any existing legal framework to 
    regulate flow directly. Some commenters stated that developing federal 
    parameters for the control of water quantity, i.e. flow, would result 
    in federal intrusion into land use planning, an authority that they 
    claim is solely within the purview of State governments and their 
    political subdivisions.
        EPA is not attempting to regulate flow via the ``no exposure'' 
    provisions. EPA does agree, however, that increases in impervious 
    surfaces can result in increased runoff volumes from the site which in 
    turn may increase pollutant loading. In addition, the Agency notes that 
    in some States water quality standards include water quality criteria 
    for flow or turbidity. Therefore, in order to provide a minimal amount 
    of information on possible impacts from increased pollutant loading and 
    runoff volume, EPA's ``no exposure'' certification form (see Appendix 
    4) asks the discharger to indicate if they have paved or roofed over a 
    formerly exposed, pervious area in order to qualify for the ``no 
    exposure'' exclusion. If the answer is yes, the discharger must 
    indicate, by choosing from three possible responses, approximately how 
    much impervious area was created to achieve ``no exposure''. The 
    choices are: (1) less than 1 acre, (2) 1 to 5 acres, and (3) more than 
    5 acres. This requirement provides additional information that will aid 
    in determining if discharges from the facility are causing adverse 
    receiving water impacts. EPA intends to prevent water quality impacts 
    resulting from increased discharges of pollutants, which may result 
    from increased volume of runoff. In many cases, consideration of the 
    increased flow rate, velocity and energy of storm water discharges, 
    following construction of large amounts of impervious surfaces, must be 
    taken into consideration in order to reduce the discharge of 
    pollutants, to meet water quality standards and to prevent degradation 
    of receiving streams. EPA recommends that dischargers consider these 
    factors when making modifications to their site in order to qualify for 
    the ``no exposure'' exclusion.
    2. Today's Rule
        In order to claim relief under the ``no exposure'' provision, the 
    discharger of an otherwise regulated facility must submit a no exposure 
    certification that incorporates the questions of Sec. 122.26(g)(4)(iii) 
    to the NPDES permitting authority once every 5 years. This provision 
    applies across all categories of industrial activity covered by the 
    existing program, except discharges from construction activities.
        In addition to submitting a ``no exposure'' certification every 5 
    years, the facility must allow the NPDES permitting authority or 
    operator of an MS4 (where there is a storm water discharge to the MS4) 
    to inspect the facility and to make such inspection reports publicly 
    available upon request. Also, upon request, the facility must submit a 
    copy of the ``no exposure'' certification to the operator of the MS4 
    into which the facility discharges (if applicable). All ``no exposure'' 
    certifications must be signed in accordance with the signatory 
    requirements of Sec. 122.22. The ``no exposure'' certification is non-
    transferable. In the event that the facility operator changes, the new 
    discharger must submit a new ``no exposure'' certification.
    
    [[Page 68784]]
    
        Members of the FACA Committee urged that EPA not allow dischargers 
    certifying ``no exposure'' to take actions to qualify for this 
    provision that result in a net environmental detriment. In developing a 
    regulatory implementation mechanism, however, EPA found that the phrase 
    ``no net environmental detriment,'' was too imprecise to use within 
    this context. Therefore, today's rule addresses this issue by requiring 
    information that should help the permitting authority to determine 
    whether actions taken to qualify for the exclusion interfere with the 
    attainment or maintenance of water quality standards, including 
    designated uses. Permitting authorities will be able, where necessary, 
    to make a determination by evaluating the activities that changed at 
    the industrial site to achieve ``no exposure'', and assess whether 
    these changes cause an adverse impact on, or have the reasonable 
    potential to cause an instream excursion of, water quality standards, 
    including designated uses. EPA anticipates that many efforts to achieve 
    ``no exposure'' will employ simple good housekeeping and contaminant 
    cleanup activities. Other efforts may involve moving materials and 
    industrial activities indoors into existing buildings or structures.
        In very limited cases, industrial operators may make major changes 
    at a site to achieve ``no exposure''. These efforts may include 
    constructing a new building or cover to eliminate exposure or 
    constructing structures to prevent run-on and storm water contact with 
    industrial materials or activities. Where major changes to achieve ``no 
    exposure'' increase the impervious area of the site, the facility 
    operator must provide this information on the ``no exposure'' 
    certification form as discussed above. Using this and other available 
    data and information, permitting authorities should be able to assess 
    whether any major change has resulted in increased pollutant 
    concentrations or loadings, toxicity of the storm water runoff, or a 
    change in natural hydrological patterns that would interfere with the 
    attainment and maintenance of water quality standards, including 
    designated uses or appropriate narrative, chemical, biological, or 
    habitat criteria where such State or Tribal water quality standards 
    exist. In these instances, the facility operator and their NPDES 
    permitting authority should take appropriate actions to ensure that 
    attainment or maintenance of water quality standards can be achieved. 
    The NPDES permitting authority should decide if the facility must 
    obtain coverage under an individual or general permit to ensure that 
    appropriate actions are taken to address adverse water quality impacts.
        While the intent of today's ``no exposure'' provision is to reduce 
    the regulatory burdens on industrial facilities and government 
    agencies, the FACA Committee suggested that the NPDES permitting 
    authority consider a compliance assessment program to ensure that 
    facilities that have availed themselves of this ``no exposure'' option 
    meet the applicable requirements. Inspections could be conducted at the 
    discretion of the NPDES authority and be coordinated with other 
    facility inspections. EPA expects, however, that the permitting 
    authority will conduct inspections when it becomes aware of potential 
    water quality impacts possibly caused by the facility's storm water 
    discharges or when requested to do so by adversely affected members of 
    the public. The intent of this provision is that the 5 year ``no 
    exposure'' certification be fully available to, and enforceable by, 
    appropriate federal and State authorities under the CWA. Private 
    citizens can enforce against facilities for discharges of storm water 
    that are inconsistent with a ``no exposure'' certification if storm 
    water discharges from such facilities are not otherwise permitted and 
    in compliance with applicable requirements.
        EPA received comments from owners, operators and representatives of 
    Phase I facilities classified as ``light industry'' as defined by the 
    regulations at Sec. 122.26(b)(14)(xi). The comments recommended 
    maintaining the approach of the existing regulations which does not 
    require the discharger to submit any supporting documentation to the 
    permitting authority in order to claim the ``no exposure'' exclusion 
    from permitting. As discussed previously, the ``no exposure'' concept 
    was developed in response to the Ninth Circuit court's remand of part 
    of the existing rules back to EPA. The court found that EPA cannot rely 
    on the ``unverified judgment'' of the facility. The comments opposing 
    documentation did not address the ``unverified judgment'' concern.
        Today's rule is a ``conditional'' exclusion from permitting which 
    requires all categories, including the ``light industrial'' facilities 
    that have no exposure of materials to storm water, to submit a 
    certification to the permitting authority. Upon receipt of a complete 
    certification, the permitting authority can review the information, or 
    call, or inspect the facility if there are doubts about the facility's 
    ``no exposure'' claim. Also, if the facility discharges into an MS4, 
    the operator of the MS4 can request a copy of the certification, and 
    can inspect the facility. The public can request a copy of the 
    certification and/or inspection reports. In adopting these conditional 
    ``no exposure'' provisions, the Agency addressed the Ninth Circuit 
    court's ruling regarding the discharger's unverified judgment.
        EPA received one comment requesting clarification on whether the 
    anti-backsliding provisions in the regulations at Sec. 122.44(l) apply 
    to industrial facilities that are currently covered under an NPDES 
    storm water permit, and whether such facilities could qualify for the 
    ``no exposure'' exclusion under today's rule. The anti-backsliding 
    provisions will not prevent most industrial facilities that can certify 
    ``no exposure'' under today's rule from qualifying for an exclusion 
    from permitting. The anti-backsliding provisions contain 5 exceptions 
    that allow permits to be renewed, reissued or modified with less 
    stringent conditions. One exception at Sec. 122.44(l)(2)(A) allows less 
    stringent conditions if ``material and substantial alterations or 
    additions to the permitted facility occurred after permit issuance 
    which justify the application of a less stringent effluent 
    limitation.'' Section 122.44(l)(B)(1) also allows less stringent 
    requirements if ``information is available which was not available at 
    the time of permit issuance and which would have justified the 
    application of less stringent effluent limitations at the time of 
    permit issuance.'' Facility's operators who certify ``no exposure'' and 
    submit the required information once every 5 years will have provided 
    the permitting authority ``information that was not available at the 
    time of permit issuance.'' Also, some facilities may, in order to 
    achieve ``no exposure'', make ``material and substantial alterations or 
    additions to the permitted facility.'' Therefore, most facilities 
    covered under existing NPDES general permits for storm water (e.g., 
    EPA's Multi-Sector General Permit) will be eligible for the conditional 
    ``no exposure'' exclusion from permitting without concern about the 
    anti-backsliding provisions. Such dischargers will have met one or both 
    of the anti-backsliding exceptions detailed above. Facilities that are 
    covered under individual permits containing numeric limitations for 
    storm water should consult with their permitting authority to determine 
    whether the anti-backsliding provisions will prevent them from 
    qualifying for the exclusion from permitting (for that discharge point) 
    based on a certification of ``no exposure''.
    
    [[Page 68785]]
    
        EPA received several comments regarding the timing of when the ``no 
    exposure'' certification should be submitted. The proposed rule said 
    that the ``no exposure'' certification notice must be submitted ``at 
    the beginning of each permit term or prior to commencing discharges 
    during a permit term.'' Some commenters interpreted this statement to 
    mean that existing facilities can only submit the certification at the 
    time a permit is being issued or renewed. EPA intended the phrase ``at 
    the beginning of each permit term'' to mean ``once every 5 years'' and 
    today's rule reflects this clarification. EPA envisions that the NPDES 
    storm water program will be implemented primarily through general 
    permits which are issued for a 5 year term. Likewise the ``no 
    exposure'' certification term is 5 years. The NPDES permitting 
    authority will maintain a simple registration list that should impose 
    only a minor administrative burden on the permitting authority. The 
    registration list will allow for tracking of industrial facilities 
    claiming the exclusion. This change allows a facility to submit a ``no 
    exposure'' certification at any time during the term of the permit, 
    provided that a new certification is submitted every 5 years from the 
    time it is first submitted (assuming that the facility maintains a ``no 
    exposure'' status). Once a discharger has established that the facility 
    meets the definition of ``no exposure'', and submits the necessary ``no 
    exposure'' certification, the discharger must maintain their ``no 
    exposure'' status. Failure to maintain ``no exposure'' at their 
    facility could result in the unauthorized discharge of pollutants to 
    waters of the United States and enforcement for violation of the CWA. 
    Where a discharger believes that exposure could occur in the future due 
    to some anticipated change at the facility, the discharger should 
    submit an application and obtain coverage under an NPDES permit prior 
    to such discharge to avoid penalties.
        Where EPA is the permitting authority, dischargers may submit a 
    ``no exposure'' certification at any time after the effective date of 
    today's rule. Where EPA is not the permitting authority, dischargers 
    may not be able to submit the certification until the non-federal 
    permitting authority completes any necessary statutory or regulatory 
    changes to adopt this ``no exposure'' provision. EPA recommends that 
    the discharger contact the permitting authority for guidance on when 
    the ``no exposure'' certification should be submitted.
        EPA received comments on the proposed rule requirement that the 
    discharger ``must comply immediately with all the requirements of the 
    storm water program including applying for and obtaining coverage under 
    an NPDES permit,'' if changes occur at the facility which cause 
    exposure of industrial activities or materials to storm water. The 
    comments expressed the difficultly of immediate compliance. EPA expects 
    that most facility changes can be anticipated, therefore dischargers 
    should apply for and obtain NPDES permit coverage in advance of changes 
    that result in exposure to industrial activities or materials. 
    Permitting authorities may grant additional time, on a case-by-case 
    basis, for preparation and implementation of a storm water pollution 
    prevention plan.
        Finally, today's rule at Sec. 122.26(g)(4) includes the information 
    which must be included on the ``no exposure'' certification. Authorized 
    States, Tribes or U.S. Territories may develop their own form which 
    includes this required information, at a minimum. EPA adopted the 
    requirements (with modification) from the draft ``No Exposure 
    Certification Form'' published as an appendix to the proposed rule. 
    Modifications were made to the draft form to address comments received 
    and to streamline the required information. EPA included these 
    certification requirements in today's rule in order to preserve its 
    integrity. Dischargers in areas where EPA is the permitting authority 
    should use the ``No Exposure Certification'' form included in Appendix 
    4.
    3. Definition of ``No Exposure''
        For purposes of this section, ``no exposure'' means that all 
    industrial materials or activities are protected by a storm resistant 
    shelter to prevent exposure to rain, snow, snowmelt, and/or runoff. 
    Industrial materials or activities include, but are not limited to, 
    material handling equipment or activities, industrial machinery, raw 
    materials, intermediate products, by-products, final products, or waste 
    products. Material handling activities include the storage, loading and 
    unloading, transportation, or conveyance of any raw material, 
    intermediate product, final product or waste product. However, storm 
    resistant shelter is not required for: (1) Drums, barrels, tanks, and 
    similar containers that are tightly sealed, provided those containers 
    are not deteriorated and do not leak; (2) adequately maintained 
    vehicles used in material handling; and (3) final products, other than 
    products that would be mobilized in storm water discharge (e.g., rock 
    salt). Each of these three exceptions to the no exposure definition are 
    discussed in more detail below.
        EPA intends the term ``storm resistant shelter'' to include 
    completely roofed and walled buildings or structures, as well as 
    structures with only a top cover but no side coverings, provided 
    material under the structure is not otherwise subject to any run-on and 
    subsequent runoff of storm water. While the Agency intends that this 
    provision promote permanent ``no exposure'', EPA understands that 
    certain vehicles could pass between buildings and, during passage, be 
    exposed to rain and snow. Adequately maintained vehicles such as 
    trucks, automobiles, forklifts, or other such general purpose vehicles 
    at the industrial site that are not industrial machinery, and that are 
    not leaking contaminants or are not otherwise a source of industrial 
    pollutants, could be exposed to precipitation or runoff. Such 
    activities alone does not prevent a discharger from being able to 
    certify no exposure under this provision. Similarly, trucks or other 
    vehicles awaiting maintenance at vehicle maintenance facilities, as 
    defined at Sec. 122.26(b)(14)(viii), that are not leaking contaminants 
    or are not otherwise a source of industrial pollutants, are not 
    considered exposed.
        In addition, EPA recognizes that there are circumstances where 
    permanent ``no exposure'' of industrial activities or materials is not 
    possible. Under such conditions, materials and activities may be 
    sheltered with temporary covers, such as tarps, between periods of 
    permanent enclosure. The final rule does not specify every such 
    situation. EPA intends that permitting authorities will address this 
    issue on a case-by-case basis. Permitting authorities can determine the 
    circumstances under which temporary structures will or will not meet 
    the requirements of this section. Until permitting authorities 
    specifically determine otherwise, EPA recommends application of the 
    ``no exposure'' exclusion for temporary sheltering of industrial 
    materials or activities only during facility renovation or 
    construction, provided that the temporary shelter achieves the intent 
    of this section. Moreover, ``exposure'' that results from a leak in 
    protective covering would only be considered ``exposure'' if not 
    corrected prior to the next storm water discharge event. EPA received 
    one comment requesting that this allowance for temporary shelter be 
    limited to facility renovation or construction directly related to the 
    industrial activity requiring temporary shelter, and be scheduled to 
    minimize the use of temporary shelter. Another comment suggested 
    placing time limits
    
    [[Page 68786]]
    
    on the use of temporary shelter. The commenter did not recommend a 
    specific time period, rather the comment said that renovation in some 
    instances may take years, and that EPA should not allow temporary 
    shelter over prolonged periods. EPA agrees that the use of temporary 
    shelter must be related to the renovation or construction at the site, 
    and be scheduled or designed to minimize the use of temporary shelter. 
    Further, EPA agrees that the use of temporary shelter should be limited 
    in duration, but does not intend to define ``temporary'' or ``prolonged 
    period''.
        Many final products are intended for outdoor use and pose little 
    risk of storm water contamination, such as new cars. Therefore, final 
    products, except those that can be mobilized in storm water discharge, 
    can be ``exposed'' and still allow the discharge to certify ``no 
    exposure''. EPA intends the term ``final products'' to mean those 
    products that are not used in producing another product. Any product 
    that can be used to make another product is considered an 
    ``intermediate product.'' For example, a facility that makes horse 
    trailers can store the finished trailers outdoors as a final product. 
    The storage of those final products does not prevent eligibility to 
    claim ``no exposure''. However, any facility that makes parts for the 
    horse trailers (e.g., metal tubing, sheet metal, paint) is not eligible 
    for the ``no exposure'' exclusion from permitting if those 
    ``intermediate products'' are stored outdoors (i.e., ``exposed'').
        EPA received comments related to materials in drums, barrels, tanks 
    and similar containers. Some comments objected to the language in the 
    preamble to the proposed rule that would have recommended that the 
    ``exposure'' determination for drums and barrels be based on the 
    ``potential to leak.'' Those comments said that all drums and barrels 
    have the potential to leak, thereby making certification impossible. 
    They recommended allowing outdoor storage of drums and barrels except 
    for those that ``are leaking'' at the time of certification. Other 
    comments suggested allowing drums and barrels to be stored outside only 
    if the drums and barrels: are empty; have secondary containment; or 
    there is a spill contingency plan in place. Opposing comments suggested 
    that allowing outdoor exposure of drums and barrels, based on existing 
    integrity and condition, is inconsistent with the ``however packaged'' 
    proposed rule language, and also would not satisfy the Ninth Circuit 
    remand. The comments point out that the former rule was invalidated by 
    the court in part because it relied on the ``unverified judgment'' of 
    the light industrial facility operator to determine the non-
    applicability of the permit requirements, and that allowing the 
    facility operator to determine the condition of their drums and barrels 
    would result in the same flaw.
        In response, EPA believes that drums and barrels that are stored 
    outdoors pose little risk of storm water contamination unless they are 
    open, deteriorated or leaking. The Agency has modified today's rule 
    accordingly. EPA intends the term ``open'' to mean any container that 
    is not tightly sealed and ``sealed'' to mean banded or otherwise 
    secured and without operational taps or valves. Drums, barrels, tanks, 
    and similar containers may only be stored outdoors under this 
    conditional exclusion. The addition of material to or withdrawing of 
    material from these containers while outside is deemed ``exposure''. 
    Moving the containers while outside does not create ``exposure'' 
    provided that the containers are not open, deteriorated or leaking. In 
    order to complete the ``no exposure'' certification, a facility 
    operator must inspect all drums, barrels, tanks or other containers 
    stored outside to ensure that they are not open, deteriorated, or 
    leaking. EPA recommends that the discharger designate someone at the 
    facility to conduct frequent inspections to verify that the drums, 
    barrels, tanks or other containers remain in a condition such that they 
    are not open, deteriorated or leaking. Drums, barrels, tanks or other 
    containers stored outside that have valves which are used to put 
    material in or take material out of the container, and that have 
    dripped or may drip, are considered to be ``leaking'' and must be under 
    a storm resistant shelter in order to qualify for the no exposure 
    exclusion. Likewise, leaking pipes containing contaminants exposed to 
    storm water are deemed ``exposed.'' If at any time drums, barrels, 
    tanks or similar containers are opened, deteriorated or leaking, the 
    discharger should take immediate actions to close or replace the 
    container. Any resulting unpermitted discharge would violate the CWA. 
    The Director, the operator of the MS4, or the municipality may inspect 
    the facility to verify that all of the applicable areas meet the ``no 
    exposure'' conditions as specified in the rule language. In requiring 
    submission of the conditional ``no exposure'' certification and 
    allowing the permitting authority and the operator of the MS4 to 
    inspect the facility, today's rule does not rely on the unverified 
    judgment of the facility to determine that the no exposure provision is 
    being met.
        EPA received several comments related to trash dumpsters that are 
    located outside. The preamble to the proposed rule listed dumpsters in 
    the same grouping as drums and barrels, which based exposure on the 
    ``potential to leak''. Today's rule distinguishes between dumpsters and 
    drums/barrels. In the Phase I Question and Answer document (volume 1, 
    question 52) the Agency noted that a covered dumpster containing waste 
    material that is kept outside is not considered ``exposed'' as long as 
    ``the container is completely covered and nothing can drain out holes 
    in the bottom, or is lost in loading onto a garbage truck.'' EPA 
    affirms this approach today. Industrial refuse and industrial trash 
    that is left uncovered is deemed ``exposed.''
        For purposes of this provision, particulate matter emissions from 
    roof stacks/vents that are regulated and in compliance under other 
    environmental protection programs, such as air quality control 
    programs, and that do not cause storm water contamination, are 
    considered ``not exposed.'' EPA received comments on the phrase in the 
    draft ``no exposure'' certification form that asked whether 
    ``particulate emissions from roof stacks/vents not otherwise regulated, 
    and in quantities detectable in the storm water outflow,'' are exposed 
    to precipitation. One comment expressed concern that the phrase ``in 
    quantities detectable in the storm water outflow'' implies that the 
    facility must conduct monitoring prior to completing the checklist, and 
    must continue to monitor after receiving the no exposure exclusion, in 
    order to be able to verify compliance with the no exposure provision. 
    Another comment said that current measurement technology allows 
    detection of pollutants at levels that may not cause environmental 
    harm. EPA does not intend to require monitoring of runoff from 
    facilities with roof stacks/vents prior to or after completing and 
    submitting the no exposure certification. EPA has thus replaced the 
    phrase ``in quantities detectable'' with ``evident'' to convey the 
    message that emissions from some roof stacks/vents have the potential 
    to contaminate storm water discharges in quantities that are considered 
    significant or that cause or contribute to a water quality standards 
    violation. In those instances where the permitting authority determines 
    that particulate emissions from facility roof stacks/vents are a 
    significant contributor of pollutants or contributing to water quality 
    violations, the permitting authority may require the discharger to 
    apply for and obtain coverage under a
    
    [[Page 68787]]
    
    permit. Visible deposits of residuals (e.g., particulate matter) near 
    roof or side vents are considered ``exposed''. Likewise, visible 
    ``track out'' (i.e., pollutants carried on the tires of vehicles) or 
    windblown raw materials are deemed ``exposed.''
        EPA received a comment requesting an allowance under the ``no 
    exposure'' provision for industrial facilities with several outfalls at 
    a site where some, but not all of the outfalls drain non-exposed areas. 
    The commenter provided an example of an industrial facility that has 5 
    outfalls draining different areas of the site, where two of those 
    outfalls drain areas where industrial activities or materials are not 
    exposed to storm water. The comment requested that the facility in this 
    example be allowed to submit a ``no exposure'' certification in order 
    to be relieved of permitting obligations for discharges from those two 
    outfalls.
        EPA agrees, but the comment would be implemented on an outfall-by-
    outfall basis in the permitting process, not through the ``no 
    exposure'' exclusion. The ``no exposure'' provision was developed to 
    allow exclusion from permitting of discharges from entire industrial 
    facilities (except construction), based on a claim of ``no exposure'' 
    for all areas of the facility where industrial materials or activities 
    occur. Where exposure to industrial materials or activities exist at 
    some but not all areas of the facility, the ``no exposure'' exclusion 
    from permitting is not allowed because permit coverage is still 
    required for storm water discharges from the exposed areas. Relief from 
    permit requirements for outfalls draining non-exposed areas should be 
    addressed through the permit process, in coordination with the 
    permitting authority. Most NPDES general permits for storm water 
    discharge provide enough flexibility to allow minimal or no 
    requirements for non-exposed areas at industrial facilities. If the 
    permitting authority determines that additional flexibility is needed 
    for this scenario, the permits could be modified as necessary.
    
    K. Public Involvement/Public Role
    
        The Phase II FACA Subcommittee discussed the appropriate role of 
    the public in successful implementation of a municipal storm water 
    program. EPA believes that an educated and actively involved public is 
    essential to a successful municipal storm water program. An educated 
    public increases program compliance from residents and businesses as 
    they realize their individual and collective responsibility for 
    protecting water resources (e.g., the residents and businesses could be 
    subject to a local ordinance that prohibits dumping used oil down storm 
    sewers). Finally, the program is also more likely to receive public 
    support and participation when the public is actively involved from the 
    program's inception and allowed to participate in the decision making 
    process.
        In a time of limited staff and financial resources, public 
    volunteers offer diverse backgrounds and expertise that may be used to 
    plan, develop, and implement a program that is tailored to local needs 
    (e.g., participate in public meetings and other opportunities for 
    input, perform lawful volunteer monitoring, assist in program 
    coordination with other preexisting and related programs, aid in the 
    development and distribution of educational materials, and provide 
    public training activities). The public's participation is also useful 
    in the areas of information dissemination/education and reporting of 
    violators, where large numbers of community members can be more 
    effective than a few regulators.
        The public can also petition the NPDES permitting authority to 
    require an NPDES permit for a discharge composed entirely of storm 
    water that contributes to a violation of a water quality standard or is 
    a significant contributor of pollutants to waters of the United States. 
    In evaluating such a petition, the NPDES permitting authority is 
    encouraged to consider the set of designation criteria developed for 
    the evaluation of small MS4s located outside of an urbanized area in 
    places with a population of at least 10,000 and a population density of 
    1,000 or more. Furthermore, any person can protect water bodies by 
    taking civil action under section 505 of the CWA against any person who 
    is alleged to be in violation of an effluent standard or permit 
    condition. If civil action is taken, EPA encourages citizen plaintiffs 
    to resolve any disagreements or concerns directly with the parties 
    involved, either informally or through any available alternative 
    dispute resolution process.
        EPA recognizes that public involvement and participation pose 
    challenges. It requires a substantial initial investment of staff and 
    financial resources, which could be very limited. Even with this 
    investment, the public might not be interested in participating. In 
    addition, public participation could slow down the decision making 
    process. However, the benefits are numerous.
        EPA encourages members of the public to contact the NPDES 
    permitting authority or local MS4s operator for information on the 
    municipal storm water program and ways to participate. Such information 
    may also be available from local environmental, nonprofit and industry 
    groups.
        Some commenters stressed the need to suggest to the public that 
    they have a responsibility to fund the municipal storm water program. 
    While EPA believes it is important that the program be adequately 
    funded, today's rule does not address appropriate mechanisms or levels 
    for such funding.
        EPA received comments expressing concern that considerable public 
    involvement requirements could result in increased litigation. EPA is 
    not convinced there is a correlation between meaningful public 
    education programs and any increased probability of litigation.
        Finally, EPA received comments stating that the Agency should not 
    en courage volunteer monitoring unless proper procedures are followed. 
    EPA agrees. EPA encourages only lawful monitoring, i.e., obtaining the 
    necessary approval if there is any question about lawful access to 
    sites. Moreover, as a matter of good practice and to enhance the 
    validity and usefulness of the results, any party, public or private, 
    conducting water quality monitoring is encouraged to use appropriate 
    quality control procedures and approved sampling and analytic methods.
    
    L. Water Quality Issues
    
    1. Water Quality Based Effluent Limits
        In addition to technology based requirements, all point source 
    discharges of industrial storm water are subject to more stringent 
    NPDES permitting requirements when necessary to meet water quality 
    standards. CWA sections 402(p)(3)(A) and 301(b)(1)(C). For municipal 
    separate storm sewers, EPA or the State may determine that other permit 
    provisions (e.g. one of the minimum measures) are appropriate to 
    protect water quality and, for discharges to impaired waters, to 
    achieve reasonable further progress toward attainment of water quality 
    standards pending implementation of a TMDL. CWA section 
    402(p)(3)(B)(iii). See Defenders of Wildlife, et al. Browner, No. 98-
    71080 (9th cir., August 11, 1999). Discharges of storm water also must 
    comply with applicable antidegradation policies and implementation 
    methods to maintain and protect water quality. 40 CFR 131.12. Section 
    122.34(a) emphasizes this point by specifically noting that a storm 
    water management program designed to reduce the discharge of pollutants 
    from the storm sewer system ``to the maximum extent practicable'' is 
    also designed to protect water quality.
    
    [[Page 68788]]
    
    Permits issued to non-municipal sources of storm water must include 
    water quality-based effluent limits where necessary to meet water 
    quality standards.
        Commenters challenged EPA's interpretation of the CWA as requiring 
    water quality-based effluent limits for MS4s when necessary to protect 
    water quality. Commenters asserted that CWA 402(p)(3)(B), which 
    addresses permit requirements for municipal discharges, limits the 
    scope of municipal program requirements to an effective prohibition on 
    non-storm water discharges to a separate storm sewer and to controls 
    which reduce pollutants to the ``maximum extent practicable, including 
    management practices, control techniques and system design and 
    engineering methods.'' They asserted that the final rule should clarify 
    that neither numeric nor narrative water quality-based limits are 
    appropriate or authorized for MS4s.
        EPA disagrees that section 402(p)(3) divests permitting authorities 
    of the tools necessary to issue permits to meet water quality 
    standards. Section 402(p)(3)(B)(iii) specifically preserves the 
    authority for EPA or the State to include other provisions determined 
    appropriate to reduce pollutants in order to protect water quality. 
    Defenders of Wildlife, slip op. at 11688. Small MS4s regulated under 
    today's rule are designated under CWA 402(p)(6) ``to protect water 
    quality.''
        Commenters argued that water quality standards, particularly 
    numeric criteria, were not designed to address storm water discharges. 
    The episodic nature and magnitude of storm water events, they argue, 
    make it impossible to apply the ``end of pipe'' compliance assessment 
    approach, for example, in the development of water quality based 
    effluent limits.
        EPA's disagrees with the commenters arguments about the inability 
    of water quality criteria to address high flow conditions. Today's 
    final rule does, however, address the concern that numeric effluent 
    limits will necessitate end of pipe treatment and the need to provide a 
    workable alternative.
        Today's rule was developed under the approach outlined in the 
    Interim Permitting Policy for Water Quality-Based Effluent Limitations 
    in Storm Water Permits, issued on August 1, 1996. 61 FR 43761 (November 
    26, 1996) (the ``Interim Permitting Policy''). EPA intends to issue 
    NPDES permits consistent with the Interim Permitting Policy, which 
    provides as follows:
        In response to recent questions regarding the type of water 
    quality-based effluent limitations that are most appropriate for NPDES 
    storm water permits, EPA is adopting an interim permitting approach for 
    regulating wet weather storm water discharges. Due to the nature of 
    storm water discharges, and the typical lack of information on which to 
    base numeric water quality-based effluent limitations (expressed as 
    concentration and mass), EPA will use an interim permitting approach 
    for NPDES storm water permits.
        ``The interim permitting approach uses best management practices 
    (BMPs) in first-round storm water permits, and expanded or better-
    tailored BMPs in subsequent permits, where necessary, to provide for 
    the attainment of water quality standards. In cases where adequate 
    information exists to develop more specific conditions or limitations 
    to meet water quality standards, these conditions or limitations are to 
    be incorporated into storm water permits, as necessary and appropriate. 
    This interim permitting approach is not intended to affect those storm 
    water permits that already include appropriately derived numeric water 
    quality-based effluent limitations. Since the interim permitting 
    approach only addresses water quality-based effluent limitations, it 
    also does not affect technology-based effluent limitations, such as 
    those based on effluent limitations guidelines or developed using best 
    professional judgment, that are incorporated into storm water permits.
        ``Each storm water permit should include a coordinated and cost-
    effective monitoring program to gather necessary information to 
    determine the extent to which the permit provides for attainment of 
    applicable water quality standards and to determine the appropriate 
    conditions or limitations of subsequent permits. Such a monitoring 
    program may include ambient monitoring, receiving water assessment, 
    discharge monitoring (as needed), or a combination of monitoring 
    procedures designed to gather necessary information.
        ``This interim permitting approach applies only to EPA; however, 
    EPA also encourages authorized States and Tribes to adopt similar 
    policies for storm water permits. This interim permitting approach 
    provides time, where necessary, to more fully assess the range of 
    issues and possible options for the control of storm water discharges 
    for the protection of water quality. This interim permitting approach 
    may be modified as a result of the ongoing Urban Wet Weather Flows 
    Federal Advisory Committee policy dialogue on this subject.''
        One commenter challenged the Interim Permitting Policy on a 
    procedural basis, arguing that it was published without opportunity for 
    public notice and comment. In response, EPA notes that the Policy was 
    included verbatim and made available for public comment in the proposal 
    to today's final rule. Prior to that proposal, the Agency defended the 
    application of the Policy on a case-by-case basis in individual permit 
    proceedings. Moreover, the essential elements of the Policy--that 
    narrative effluent limitations are the most appropriate form of 
    effluent limitations for storm water dischargers from municipal 
    sources--was inherent in Sec. 122.34(a) of the proposed rule, and was 
    the subject of extensive public comment. In any event, the Policy does 
    not constitute a binding obligation. It is policy, not regulation.
        Consistent with the recognition of data needs underlying the 
    Policy, EPA will evaluate the small MS4 storm water regulations after 
    the second round of permit issuance. Section 122.34(e)(2) of today's 
    rule expressly provides that for the interim ten-year period, ``EPA 
    strongly recommends that until the evaluation of the storm water 
    program in Sec. 122.37, no additional requirements beyond the minimum 
    control measures be imposed on regulated small MS4s without the 
    agreement of the operator of the affected small MS4, except where an 
    approved TMDL or equivalent analysis provides adequate information to 
    develop more specific measures to protect water quality.'' This 
    approach addresses the concern for protecting water resources from the 
    threat posed by storm water discharges with the important qualification 
    that there must be adequate information on the watershed or a specific 
    site as a basis for requiring tailored storm water controls beyond the 
    minimum control measures. As indicated, the Interim Permitting Policy 
    has several important limitations--it does not apply to technology-
    based controls or to sources that already have numeric end of pipe 
    effluent limitations. EPA encourages authorized States and Tribes to 
    adopt policies similar to the Interim Permitting Policy when developing 
    storm water discharge programs. For a discussion of appropriate 
    monitoring activities, see Section H.3.d., Evaluation and Assessment.
        Where a water quality analysis indicates there is a need and basis 
    for deriving water quality-based effluent limits in NPDES permits for 
    storm water discharges regulated under today's rule, EPA believes that 
    most of these cases would be satisfied by narrative effluent
    
    [[Page 68789]]
    
    limitations that require the implementation of BMPs. NPDES permit 
    limits will in most cases continue to be based on the specific approach 
    outlined in today's rule for the implementation of BMPs as the most 
    appropriate form of effluent limitation to satisfy technology and water 
    quality-based requirements. See Sec. 122.34(a). For storm water 
    management plans with existing BMPs, this may require further tailoring 
    of BMPs to address the pollutant(s) of concern, the nature of the 
    discharge and the receiving water. If the permitting authority 
    determines that, through implementation of appropriate BMPs required by 
    the NPDES storm water permit, the discharge has the necessary controls 
    to provide for attainment of water quality standards, additional 
    controls are not needed in the permit. Conversely, if a discharger 
    (MS4, industrial or construction) fails to adopt and implement adequate 
    BMPs, the permittee and/or the permitting authority should consider a 
    different mix of BMPs or more specific conditions to ensure water 
    quality protection.
        Some commenters observed that there was no evidence from the 
    experience of storm water dischargers regulated under the existing 
    NPDES storm water program, or from studies or reports that allegedly 
    support EPA's position, that implementation of BMPs to satisfy the six 
    minimum control measures would meet applicable water quality standards 
    for a regulated small MS4. In response, EPA acknowledges that the six 
    minimum measures are intended to implement the statutory requirement to 
    control discharges to the maximum extent practicable, and they may not 
    result in the attainment of water quality standards in all cases. The 
    control measures do, however, focus on and address well-documented 
    threats to water quality associated with storm water discharges. Based 
    on the collective expertise of the FACA Sub-committee, EPA believes 
    that implementation of the six minimum measures will, for most 
    regulated small MS4s, be adequate to protect water quality, and for 
    other regulated small MS4s will substantially reduce the adverse 
    impacts of their discharges on water quality.
        Some commenters asserted that analyses of existing water quality 
    criteria suggest that numeric criteria for aquatic life may be 
    overprotective if applied to storm water discharges. These comments 
    maintained that an approach that prohibits exceedance of applicable 
    water quality criteria is unworkable. Various commenters recommended 
    wet weather specific criteria, variances to the criteria during wet 
    weather events, and seasonal designated uses. Other commenters noted 
    that water quality-based effluent limits in NPDES permits have 
    traditionally been developed based on dry weather flow conditions 
    (e.g., assuming critical low-flow conditions in the receiving water to 
    ensure protection of aquatic life and human health). Wet weather 
    discharges, however, typically occur under high-flow conditions in the 
    receiving water. Assumptions regarding mass balance equations and size 
    of mixing zones may also not be pertinent during wet weather.
        EPA acknowledges the need to devise a regulatory program that is 
    both flexible enough to accommodate the episodic nature, variability 
    and volume of wet weather discharges and prescriptive enough to ensure 
    protection of the water resource. EPA believes that wet weather 
    discharges can be adequately addressed in the existing regulations 
    through refining designated uses and assigning criteria that are 
    tailored to the level of water quality protection described by the 
    refined designated use.
        EPA believes that lack of precision in assigning designated uses 
    and corresponding criteria by States and Tribes, in many cases may 
    result in application of water quality criteria that may not 
    appropriately match the intended condition of the water body. States 
    and Tribes have frequently designated uses without regard to site-
    specific wet weather conditions. Because certain uses (swimming, for 
    example) might not exist during high-intensity storm events or in the 
    winter, States may factor such climatic conditions and seasonal uses 
    into their use designations with appropriate analyses. This would 
    acknowledge that a lower level of control, at lower compliance cost, 
    would be appropriate to protect that use. Before modifying any 
    designated use, however, States would need to evaluate the effect of 
    less stringent water quality criteria on protecting other uses, 
    including any threatened or endangered species, drinking water supplies 
    and downstream uses. EPA will further evaluate these issues in the 
    context of the Water Quality Standards Regulation, Advance Notice of 
    Proposed Rule Making (ANPRM), 63 FR, 36742, July 7, 1998.
        One of the major themes presented by EPA in the ANPRM is that 
    refinement in use designations and tailoring of water quality criteria 
    to match refined use designations is an important future direction of 
    the water quality standards program. In assigning criteria to protect 
    general use classifications, a State or Tribe must ensure that the 
    criteria are sufficiently protective to safeguard the full range of 
    waters of the State, i.e., criteria would be based on the most 
    sensitive use. This approach has been disputed, especially for aquatic 
    life uses, where evidence suggests that the general use criteria will 
    require controls more stringent than needed to protect the existing or 
    potential aquatic life community for a specific water body. EPA 
    recognizes that there is a growing need to more precisely tailor use 
    descriptions and criteria to match site-specific conditions, ensuring 
    that uses and criteria provide an appropriate level of protection, 
    which, to the extent possible, are not overprotective. EPA is engaged 
    in an ongoing evaluation of its regulations in this area through the 
    ANPRM effort. At the same time, EPA continues to encourage States and 
    Tribes to review the applicability of the designated uses and 
    associated criteria using existing provisions in the water quality 
    standards regulation.
    2. Total Maximum Daily Loads and Analysis To Determine the Need for 
    Water Quality-Based Limitations
        The development and implementation of total maximum daily loads 
    (TMDLs) provide a link between water quality standards and effluent 
    limitations. CWA section 303(d) requires States to develop TMDLs to 
    provide more stringent water quality-based controls when technology-
    based controls are inadequate to achieve applicable water quality 
    standards. A TMDL is the sum of the individual wasteload allocations 
    for point sources and load allocations for nonpoint sources, with 
    consideration for natural background conditions. A TMDL quantifies the 
    maximum allowable loading of a pollutant to a water body and allocates 
    this maximum load to contributing point and nonpoint sources so that 
    water quality criteria will not be exceeded and designated uses will be 
    protected. A TMDL also includes a margin of safety to account for 
    uncertainty about the relationship between pollutant loads and water 
    quality.
        Today's final rule refers to TMDLs in several provisions. For the 
    purpose of today's rule, EPA relies on the component of the TMDL that 
    evaluates existing conditions and allocates loads. For discharges to 
    waters that are not impaired and for which a TMDL has not been 
    developed, today's rule also refers to an ``equivalent analysis.'' The 
    discussion that follows uses the term ``TMDL'' for both.
        Under revised Sec. 122.26(a)(9)(i)(C), the permitting authority may 
    designate
    
    [[Page 68790]]
    
    storm water discharges that require NPDES permits based on TMDLs that 
    address the pollutants of concern. For storm water discharges 
    associated with small construction activity, Sec. 122.26(b)(15)(i)(B) 
    provides a waiver provision where it may be determined that storm water 
    controls are not needed based on TMDLs that address sediment and any 
    other pollutants of concern. The NPDES permitting authority may waive 
    requirements under the program for certain small MS4s within urbanized 
    areas serving less than 1,000 persons provided that, if the small MS4 
    discharges any pollutant that has been identified as a cause of 
    impairment of a water body into which it discharges, the discharge is 
    in compliance with a wasteload allocation in a TMDL for the pollutant 
    of concern. The permitting authority may also waive requirements for 
    MS4s in urbanized areas serving between 1,000 and 10,000 persons, if 
    the permitting authority determines that storm water controls are not 
    needed, as provided in Sec. 123.35(d)(2). See Sec. 122.32(c).
        Under CWA section 303(d), States identify which of their water 
    bodies need TMDLs and rank them in order of priority. Generally, once a 
    TMDL has been completed for one or more pollutants in a water body, a 
    wasteload allocation for each point source discharging the pollutant(s) 
    is implemented as an enforceable condition in the NPDES permit. 
    Regulated small MS4s are essentially like other point source discharges 
    for purposes of the TMDL process.
        A TMDL and the resulting wasteload allocations for pollutant(s) of 
    concern in a water body may not be available because the water body is 
    not on the State's 303(d) list, the TMDL has not yet been completed, or 
    the TMDL did not include specific pollutants of concern. In these 
    cases, the permitting authority must determine whether point sources 
    discharge pollutant(s) in amounts that cause, have the reasonable 
    potential to cause, or contribute to excursions above State water 
    quality standards, including narrative water quality criteria. This so-
    called ``reasonable potential'' analysis is intended to determine 
    whether and for what pollutants water quality based effluent limits are 
    required. The analysis is, in effect, a substitute for a similar 
    determination that would be made as part of a TMDL, where necessary. 
    When ``reasonable potential'' exists, regulations at Sec. 122.44(d) 
    require a water quality-based effluent limit for the pollutant(s) of 
    concern in NPDES permits. The water quality-based effluent limits may 
    be narrative requirements to implement BMPs or, where necessary, may be 
    numeric pollutant effluent limitations.
        Commenters, generally from the regulated community, objected that, 
    due to references to the need to develop a program ``to protect water 
    quality'' and to additional NPDES permit requirements beyond the 
    minimum control measures based on TMDLs or their equivalent, regulated 
    small MS4s will be subject to uncertain permit limitations beyond the 
    six minimum control measures. Commenters also asserted that through the 
    imposition of a wasteload allocation under a TMDL in impaired water 
    bodies, there is a likelihood that unattainable, yet enforceable 
    narrative and numeric standards will be imposed on regulated small 
    MS4s.
        As is discussed in the preceding section, NPDES permits must 
    include any more stringent limitations when necessary to meet water 
    quality standards. However, even if a regulated small MS4 is subject to 
    water quality based effluent limits, such limits may be in the form of 
    narrative effluent limitations that require the implementation of BMPs. 
    As discussed earlier, EPA has adopted the Interim Permitting Policy and 
    incorporated it in the development of today's rule to recognize the 
    appropriateness of BMP-based limits developed on a case-by-case basis.
        EPA formed a Federal Advisory Committee to provide advice to EPA on 
    identifying water quality-limited water bodies, establishing TMDLs for 
    them as appropriate, and developing appropriate watershed protection 
    programs for these impaired waters in accordance with CWA section 
    303(d). Operating under the auspices of the National Advisory Council 
    for Environmental Policy and Technology (NACEPT), the committee 
    produced its Report of the Federal Advisory Committee on the Total 
    Maximum Daily Load (TMDL) Program (July 1998). EPA recently published a 
    proposed rule to implement the Report's recommendations (64 FR 46012, 
    August 23, 1999).
    3. Anti-Backsliding
        In general, the term ``anti-backsliding'' refers to statutory 
    provisions at CWA sections 303(d)(4) and 402(o) and regulatory 
    provisions at 40 CFR 122.44(l). These provisions prohibit the renewal, 
    reissuance, or modification of an existing NPDES permit that contain 
    effluent limits, permit terms, limitations and conditions, or standards 
    that are less stringent than those established in the previous permit. 
    There are also exceptions to this prohibition known as 
    ``antibacksliding exceptions.''
        The issue of backsliding from prior permit limits, standards, or 
    conditions is not expected to initially apply to most storm water 
    dischargers designated under today's proposal because they generally 
    have not been previously authorized by an NPDES permit. However, the 
    backsliding prohibition would apply if a storm water discharge was 
    previously covered under another NPDES permit. Also, the backsliding 
    prohibition could apply when an NPDES storm water permit is reissued, 
    renewed, or modified. In most cases, however, EPA does not believe that 
    these provisions would restrict revisions to storm water NPDES permits.
        One commenter questioned whether, if BMPs implemented by a 
    regulated small MS4 operator fail to produce results in removal of 
    pollutants and the permittee attempts to substitute a more effective 
    BMP, the small MS4 operator could be accused of violating the anti-
    backsliding provisions and also be exposed to citizen lawsuits. In 
    response, EPA notes that in such circumstances the MS4's permit has not 
    changed and, therefore, the prohibition against backsliding is not 
    applicable. Further, any change in the mix of BMPs that was intended to 
    be more effective at controlling pollutants would not be considered 
    backsliding, even if it did not include all of the previously 
    implemented BMPs.
    4. Water Quality-Based Waivers and Designations
        Several sections of today's final rule refer to water quality 
    standards in identifying those storm water discharges that are and are 
    not required to be permitted under today's rule. As noted in 
    Sec. 122.30 of today's rule, CWA section 402(p)(6) requires the 
    designation of municipal storm water sources that need to be regulated 
    to protect water quality and the establishment of a comprehensive storm 
    water program to regulate these sources. Requirements applicable to 
    certain municipal sources may be waived based on the absence of 
    demonstrable water quality impacts. Section 122.32(c). The section 
    402(p)(6) mandate to protect water quality also provides the basis for 
    regulating discharges associated with small construction. See also 
    Sec. 122.26(b)(15)(i). Further, today's rule carries forward the 
    existing authority for the permitting authority to designate sources of 
    storm water discharges based upon water quality considerations. Section 
    122.26(a)(9)(i)(C) and (D).
        As is discussed above in sections II.H.2.e (for small MS4s) and 
    II.I.1.b.ii
    
    [[Page 68791]]
    
    (for small construction), the requirements of today's rule may be 
    waived based on wasteload allocations that are part of ``total maximum 
    daily loads'' (TMDLs) that address the pollutants of concern or, in the 
    case of small construction and municipalities serving between 1,000 and 
    10,000 persons, the equivalents of TMDLs. One commenter stated that 
    waivers would allow exemptions to the technology based requirements and 
    would thus be inconsistent with the two-fold approach of the CWA (a 
    technology based minimum and a water quality based overlay). EPA 
    acknowledges that waivers are not allowed for other technology-based 
    requirements under the CWA. A more flexible approach is allowed, 
    however, for sources designated for regulation under 402(p)(6) to 
    protect water quality. For such sources EPA may allow a waiver where it 
    is demonstrated that an individual source does not present the threat 
    to water quality that was the basis for EPA's designation.
    
    III. Cost-Benefit Analysis
    
        EPA has determined that the range of the rule's benefits exceeds 
    the range of regulatory costs. The estimated rule costs range from 
    $847.6 million to $981.3 million annually with corresponding estimated 
    monetized annual benefits which range from $671.5 million to $1.628 
    billion, expected to exceed costs.
        The rule's cost and benefit estimates are based on an annual 
    comparison of costs and benefits for a representative year (1998) in 
    which the rule is implemented. This differs from the approach used for 
    the proposed rule which projected cost and benefits over three permit 
    terms. EPA has chosen to use the current approach because it determined 
    that the ratio of annual benefits and costs would not change 
    significantly over time. Moreover, because there is not an initial 
    outlay of capital costs with benefits accruing in the future (i.e., 
    benefits and costs are almost immediately at a steady state), it is not 
    necessary to discount costs in order to account for a time 
    differential.
        EPA developed detailed estimates of the costs and benefits of 
    complying with each of the incremental requirements imposed by the 
    rule. The Agency used two approaches, a national water quality model 
    and national water quality assessment, to estimate the potential 
    benefits of the rule. Both approaches show that the benefits are likely 
    to exceed costs.
        These estimates, including descriptions of the methodology and 
    assumptions used, are described in detail in the Economic Analysis of 
    the Final Phase II Rule, which is included in the record of this rule 
    making. Exhibit 3 summarizes costs and benefits associated with the 
    basic elements of today's rule.

    A. Costs
    
    1. Municipal Costs
        Initially, to determine municipal costs for the proposed rule, EPA 
    used anticipated expenditure data included in permit applications from 
    a sample of 21 Phase I MS4s. Certain commenters criticized the Agency 
    for using anticipated expenditures because they could be significantly 
    different from the actual expenditures. These commenters suggested that 
    the Agency use the actual cost incurred by the Phase I MS4s. Other 
    comments stated that because the Phase I MS4s, in general, are large 
    municipalities, they may not be representative of the Phase II MS4s for 
    estimating regulatory costs. Finally, one commenter noted that the 
    sample of 21 municipalities used to project cost was relatively small.
        To address the concerns of the commenters, EPA utilized a National 
    Association of Flood and Stormwater Management Agencies (NAFSMA) survey 
    of the Phase II community to obtain incremental cost estimates for 
    Phase II municipalities. Using the list of potential Phase II designees 
    published in the Federal Register (63 FR 1616), NAFSMA contacted more 
    than 1,600 jurisdictions. The goal of the survey was to solicit 
    information from those communities about the proposed Phase II NPDES 
    storm water program. Several of the survey questions corresponded 
    directly to the minimum measures required by the Phase II rule. One 
    hundred twenty-one surveys were returned to NAFSMA and were used to 
    develop municipal costs.
        Using the NAFSMA information, EPA estimated average annual per 
    household program costs for automatically designated municipalities. 
    EPA also estimated an average annual per household administrative cost 
    for municipalities to address application, record keeping, and 
    reporting requirements of the Rule. The total average per household 
    cost of the rule is expected to $9.16 per household.
        To determine potential national level costs for municipalities, EPA 
    multiplied the number of households (32.5 million) by the per household 
    cost ($9.16). EPA estimates the annual cost of the Phase II municipal 
    program at $298 million.
        As an alternative method, and point of comparison, to the NAFSMA-
    based approach, EPA reviewed actual expenditures reported from 35 Phase 
    I MS4s. The Agency targeted these 35 Phase I MS4s because they had 
    participated in the NPDES program for
    
    [[Page 68792]]
    
    nearly one permit term, were smaller in size and had detailed data 
    reflecting their actual program implementation costs. Of the 35 MS4s, 
    appropriate cost data was only available for 26 of those MS4s. EPA 
    analyzed the expenditure data and identified the relevant expenditures, 
    excluding costs presented in the annual reports unrelated to the 
    requirements of the Rule. The cost range and annual per household 
    program costs of $9.08 are similar to those found using the NAFSMA 
    survey data.
    2. Construction Costs
        In order to estimate the rule's construction-related cost on a 
    national level (the soil and erosion controls (SEC) requirements of the 
    rule and the potential impacts of the post-construction municipal 
    measure on construction), EPA estimated a per site cost for sites of 
    one, three, and five acres and multiplied these costs by the total 
    number of estimated Phase II construction starts across these size 
    categories.
        To estimate the percentage of starts subject to the soil and 
    erosion control requirements between 1 and 5 acres, with respect to 
    each category of building permits (residential, commercial, etc.), EPA 
    initially used data from Prince George's County (PGC), Maryland, and 
    applied these percentages to national totals. In the proposal, EPA 
    recognized that the PGC data may not be representative of the entire 
    country and requested data that could be used to develop better 
    estimates of the number of construction sites between 1 and 5 acres. 
    EPA did not receive any substantiated national data from commenters.
        In view of the unavailability of national data from commenters, EPA 
    made extensive efforts to collect construction site data around the 
    country. The Agency contacted more than 75 municipalities. EPA 
    determined that 14 of the contacted municipalities had useable 
    construction site data. Using data from these 14 municipalities, EPA 
    developed an estimate of the percentage of construction starts on one 
    to five acres. EPA then multiplied this percentage by the number of 
    building permits issued nationwide to determine the total number of 
    construction starts occurring on one to five acres. Finally, to isolate 
    the number of construction starts incrementally regulated by Phase II, 
    EPA subtracted the number of activities regulated under equivalent 
    programs (e.g., areas covered by the Coastal Zone Act Reauthorization 
    Amendments of 1990, and areas covered by equivalent State level soil 
    and erosion control requirements). Ultimately, EPA estimated that 
    110,223 construction starts would be incrementally covered by the rule 
    annually.
        EPA then used standard cost estimates from Building Construction 
    Cost Data and Site Work Landscape Cost Data (R.S. Means, 1997a and 
    1997b) to estimate construction BMP costs for 27 model sites in a 
    variety of typical site conditions across the United States. The model 
    sites included three different site sizes (one, three and five acres), 
    three slope variations (3%, 7%, and 12%), and three soil erosivity 
    conditions (low, medium, and high). EPA chose BMP combinations 
    appropriate to the model site conditions. Based on the assumption that 
    any combination of site factors is equally likely to occur in a given 
    site, EPA developed average cost of sediment and erosion control for 
    all model sites. EPA estimated that, on average, BMPs for a 1 acre site 
    will cost $1,206, for a 3 acre site $4,598 and for a 5 acre site 
    $8,709.
        EPA then estimated administrative costs per construction site for 
    the following elements required under the rule: Submittal of a notice 
    of intent for permit coverage; notification to municipalities; 
    development of a storm water pollution prevention plan; record 
    retention; and submittal of a notice of termination. EPA estimated the 
    average total administrative cost per site to be $937.
        EPA also considered the cost implications of NPDES permit 
    authorities waiving the applicability of requirements to storm water 
    discharges from small construction sites based on two different 
    criteria involving water quality impact and low rainfall. EPA received 
    comments stating that a waiver would require a significant investment 
    in training or acquisition of a consultant. Based on comments received, 
    EPA eliminated one of the waiver conditions involving low soil loss 
    threshold because it necessitated use of the Revised Universal Soil 
    Loss Equation which could require extensive technical expertise.
        Based on the opinions of construction industry experts, EPA 
    estimates that 15 percent of the construction sites that would 
    otherwise be covered by today's rule will be eligible to receive 
    waivers. Therefore, the Agency has excluded 15 percent of the 
    construction sites when deriving costs of sediment and erosion control. 
    The average cost for sites to qualify for the waiver is expected to be 
    $34 per site. The construction cost analysis for the proposed rule did 
    not include any costs for the preparation and submission of waiver 
    applications because EPA believed those costs would be negligible. 
    However, in response to public comments, EPA has estimated these 
    potential costs.
        EPA has also estimated the potential costs for construction site 
    operators to implement the post-construction minimum measure. These are 
    costs that may be incurred by construction site operators if the MS4 
    chooses to meet the post-construction minimum measure by requiring on-
    site structural, site-by-site control of post-construction runoff. 
    Municipalities may select from an array of structural and non-
    structural options in implementing this measure, so the potential costs 
    to construction operators is uncertain. Nonetheless, EPA developed 
    average annual BMP costs for sites of one, three, five and seven acres. 
    EPA's analysis accounted for varying levels of imperviousness that 
    characterize residential, commercial, and institutional land uses. 
    Nationwide, these costs are expected to range from $44 million to $178 
    million annually.
        Finally, to establish national incremental annual costs for Phase 
    II construction starts, EPA multiplied the total costs of compliance 
    for the chosen site size categories by the total number of Phase II 
    construction starts and added post-construction costs. EPA estimates 
    the annual compliance cost to range from $545 million to $678.7 
    million.
    
    B. Quantitative Benefits
    
        In the Economic Analysis for the proposed rule, a ``top-down'' 
    approach was used to estimate economic benefits. Under this approach, 
    the combined economic benefits for wet weather programs were estimated 
    first, and then were divided among various water programs on the basis 
    of expert opinion. As a result, the benefits estimates for an 
    individual program were rather uncertain. Moreover, this approach was 
    inconsistent with the approach used to estimate the cost of the 
    proposed storm water rule, which was developed using municipal-based 
    and cost-based data to develop ``bottom-up'' costs. Therefore, EPA 
    decided to use a ``bottom-up'' approach for estimating benefits of the 
    Phase II rule. To adequately reflect the quantifiable benefits of the 
    rule, EPA used two different methods: (1) National Water Quality Model 
    and (2) National Water Quality Assessment.
        To monetize benefits in both approaches, the Agency applied Carson 
    and Mitchell's (1993) estimates of household willingness-to-pay (WTP) 
    for water quality improvement to estimates of waters impaired by storm 
    water discharges. Carson and Mitchell's 1993 study reports the results 
    of their 1983 national survey of WTP for incremental
    
    [[Page 68793]]
    
    improvements in fresh water quality. Carson and Mitchell estimate the 
    WTP for three minimum levels of fresh water quality: boatable, 
    fishable, and sizable. EPA adjusted the WTP amounts to account for 
    inflation, growth in real per capita income, and increased attitudes 
    towards pollution control. The adjusted WTP amounts for improvements in 
    fresh water quality are $210 for boatable, $158 for fishable, and $177 
    for sizable. A brief summary of the national water quality model and 
    national water quality assessment approaches follow.
    1. National Water Quality Model
        One approach EPA used to estimate the benefits of the Phase II 
    municipal and construction site controls was the National Water 
    Pollution Control Assessment Model (NWPCAM). NWPCAM estimates benefits 
    of the storm water program at the national level, including the impact 
    on small streams. This model estimates water quality and the resultant 
    use support for the 632,000 miles of rivers and streams in the USEPA 
    Reach File Version 1 (RF1), which covers the continental United States. 
    The model analyzes water quality changes by stream reach. The 
    parameters modeled in the NWPCAM are biological oxygen demand (BOD), 
    total suspended solids (TSS), dissolved oxygen (DO), and fecal 
    coliforms (FC).
        The model projects changes in water quality due to the Phase II 
    municipal and construction site controls. To calculate the economic 
    benefits of change in water quality, the number of households in the 
    proximity of the stream reach are determined, by overlaying the model 
    results on the 1990 Census of Populated Places and Minor Civil 
    Divisions, and updating the population to 1998. Economic benefits are 
    calculated using the Carson and Mitchell WTP values. The benefits are 
    separately estimated for local and non-local waters on the basis of WTP 
    values and proximity to water quality changes.
        The value of the change in use support for local waters is greater 
    than the value of the non-local waters because of the opportunity to 
    use local waters by the local population. This model assumes that if 
    improvement occurs in waters that are not close to population centers 
    the economic value is lower. Therefore, benefits are estimated for 
    local and non-local waters separately. This assumption is based on 
    Carson and Mitchell's survey which asked respondents to apportion each 
    of their stated WTP values between achieving the water quality goals in 
    their own State and achieving those goals in the nation as a whole. On 
    average, respondents allocated 67% of their values to achieving in-
    State water quality goals and the remainder to the nation as a whole. 
    Carson and Mitchell argue that for valuing local water quality changes 
    67% is a reasonable upper bound for the local multiplier and 33% for 
    the non-local water quality changes. For the purposes of this analysis, 
    the locality is defined as urban sites and associated populations 
    linked into the NWPCAM framework. Using this methodology, the total 
    monetized benefits of Phase II control of urban and construction site 
    runoff is estimated to be $1.628 billion per year. The local and non-
    local benefits due to Phase II controls are presented in Exhibit 4.

    \1\ To estimate non-local willingness to pay per household, the 33% of willingness is multiplied by the fraction
      of previously impaired national waters (in each use category) that attain the beneficial use as a result of
      the Phase II rule. To estimate the aggregate non-local benefits, non-local willingness to pay is multiplied
      with the total number of households in the US.
    
        While the numbers of miles that are estimated to change their use 
    support are small, the benefits estimates are quite significant. This 
    is because urban runoff and, to a large extent, construction activity 
    occurs where the people actually reside and the water quality changes 
    mostly occur close to these population centers. NWPCAM indicates that 
    changes in pollution loads have the most effect immediately downstream 
    of pollution changes. As a result, the aggregate WTP is large because 
    large numbers of households in these population centers are associated 
    with the local waters that reflect improvement in designated use 
    support.
    2. National Water Quality Assessment
        EPA also estimated benefits of the Phase II Storm Water program 
    using the 1998 National Water Quality Inventory (305(b)) Report to 
    Congress, rather than the NWPCAM as a basis for estimating impairment 
    addressed by the rule. The Water Quality Assessment method separately 
    estimates benefits associated with improvements to fresh water, marine 
    water and construction site controls, and then aggregates these 
    separate categories into an estimate of total annual benefits.
    a. Municipal Measures
    
    i. Fresh Waters Benefits
    
        In order to develop estimates for the potential value of the 
    municipal measures (except storm water runoff controls for construction 
    sites), EPA applied Carson & Mitchell WTP values to estimated existing 
    and projected future fresh water impairment. Carson & Mitchell did not 
    evaluate marine waters, so only fresh water values were available from 
    their research. Even though the Carson and Mitchell estimates apply to 
    all fresh water, it is not clear how these values would be apportioned 
    among rivers, lakes, and the Great Lakes. The 305(b) data indicate that 
    lakes are the most impaired by urban runoff/storm sewers, followed 
    closely by the Great Lakes, and then rivers. Therefore, EPA applied the 
    WTP values to the categories separately and assumed that the higher 
    resulting value for lakes represents the high end of the range (i.e., 
    assuming that lake impairment is more indicative of national fresh 
    water impairment) and that the lower resulting value for impaired 
    rivers represents the low end of a value range for all fresh waters 
    (i.e., assuming that river impairment is more indicative of national 
    fresh water impairment). In addition, EPA estimated that the post-
    construction runoff
    
    [[Page 68794]]
    
    requirements of the municipal program might result in benefits of at 
    least $16.8 million annually from avoided future runoff. The post-
    construction estimate significantly underestimates potential program 
    benefits because it does not account for avoided hydrologic changes and 
    resulting water quality impairment associated with increases in 
    imperviousness from development and redevelopment. Summing the benefits 
    across the water quality use support levels yields an estimate of 
    benefits ranging from approximately $121.9 million to $378.2 million 
    per year.
    
    ii. Marine Waters Benefits
    
        In addition to the fresh water benefits captured by the Carson and 
    Mitchell study, EPA anticipates benefits as a result of improvements to 
    marine waters. Sufficient methods have not been developed to quantify 
    national-level benefits for commercial or recreational fishing. EPA 
    used beach closure data and visitation estimates from its Beach Watch 
    Program to estimate potential reductions in marine swimming visits due 
    to storm water runoff contamination events in 1997. The estimated 
    86,100 trips that did not occur because of beach closures in coastal 
    Phase II communities is a lower bound because it represents only those 
    beaches that report both closures and visitation data. EPA estimates 
    potential swimming benefits from the rule to be at least $2.1 million 
    annually.
        EPA developed an analysis of potential benefits associated with 
    avoided health impacts from exposure to contaminants in storm sewer 
    effluent. Based on a study of incremental illnesses found among people 
    who swam within one yard of storm drains in Santa Monica Bay, EPA 
    estimated a range of incremental illnesses (Haile et al., 1996). 
    Depending on assumptions made about number of exposures to contaminants 
    and contaminant concentrations, benefits ranged from $7.0 million to 
    $29.9 million annually.
    b. Construction Benefits
        The major pollutant resulting from construction activities is 
    sediment. However, in addition to sediment, construction activities 
    also yield pollutants such as pesticides, petroleum products, and 
    solvents. Because circumstances will vary considerably from site to 
    site, data is not available with which to develop estimates of benefits 
    for each site and aggregate to obtain a national-level estimate.
        In the proposed rule, EPA estimated the combined benefits of all 
    wet weather programs, and then used expert opinions to allocate them to 
    different individual programs. To eliminate the possible overlap 
    between the benefits of the soil and erosion control requirements, 
    municipal measures, and other wet weather storm water programs, EPA 
    chose to use an approach in today's final rule that directly estimates 
    the benefits of soil and erosion requirements.
        A survey of North Carolina residents (Paterson et al., 1993) 
    indicated that households are willing to pay for erosion and sediment 
    controls similar to those in today's rule. Based on income and other 
    indicators, the values derived from the study are expected to be 
    similar to values held in the rest of the country. Using the mean value 
    of the willingness to pay of $25 per household, EPA projects annual 
    benefits of the soil and erosion requirements to range from $540.5-$686 
    million.
    c. Summary of Benefits From the National Water Quality Assessment
        Total benefits from municipal measures and construction site 
    controls are expected to range from $671.5 million to $1.1 billion per 
    year, including benefits of approximately $13.7 million per year 
    associated with small stream improvements. A summary of the potential 
    benefits is presented in Exhibit 5.
        As shown in Exhibit 5, it was not possible to monetize all 
    categories of benefits using the WTP estimates. In particular, benefits 
    for improving marine water quality such as fishing and passive use 
    benefits are not included in the values used to estimate the potential 
    benefits of the municipal minimum measures (excluding construction 
    sites controls), and they are not estimated separately, because 
    information is not currently available.

    += positive benefits expected but not monetized.
    \1\ Includes water quality benefit of municipal programs, based on 80%
      effectiveness of municipal programs.
    \2\ Based on research by Carson and Mitchell (1993). Fresh water value
      only. Does not include commercial fishery, navigation, or diversionary
      (e.g. municipal drinking water cost savings or risk reductions)
      benefits. May not fully capture human health risk reduction or
      ecological values.
    \3\ Based on research by Paterson et al. (1993). Although the survey's
      description of the benefits of reducing soil erosion from construction
      sites included reduced dredging, avoided flooding, and water storage
      capacity benefits, these benefit categories may not be fully
      incorporated in the WTP values. Small streams may account for over 2%
      of total benefits.
    
    C. Qualitative Benefits
    
        There are additional benefits to storm water control that cannot be 
    quantified or monetized. Thus, the current estimate of monetized 
    benefits may understate the true value of storm water controls because 
    it omits many ways in which society is likely to benefit from reduced 
    storm water pollution, such as improved
    
    [[Page 68795]]
    
    aesthetic quality of waters, benefits to wildlife and to threatened and 
    endangered species, cultural values, and biodiversity benefits.
        A benefit that EPA did not monetize completely is the flood control 
    benefits attributable to municipal storm water controls reducing 
    downstream flooding, although flood control benefits associated with 
    sediment and erosion control are already reflected to some extent in 
    the construction benefits. Similarly, the Agency could not value the 
    benefits from increased property value due to storm water controls 
    reflected in the rule, even though a commenter suggested inclusion of 
    these benefits in the estimates.
        Moreover, while a number of commenters requested that EPA include 
    ecological benefits, the Agency was not able to fully monetize these 
    benefits. Urbanization usually increases the amount of sediment, 
    nutrients, metals and other pollutants associated with land disturbance 
    and development. Development usually not only results in a dramatic 
    increase in the volume of water runoff, but also in a substantial 
    decrease in that water's quality due to stream scour, runoff and 
    dispersion of toxic pollutants, and oversiltation. These kinds of 
    secondary benefits could not be fully reflected in the monetized 
    benefits. EPA was able to only monetize the aquatic life support 
    benefits for waters assumed to be impaired. Thus, only the aquatic life 
    support benefits attributable to municipal controls, reflected through 
    human satisfaction, are taken into account.
        Reduced nutrient level is another benefit of the storm water 
    control which is not fully captured by the economic analysis. High 
    nutrient levels often lead to eutrophication of the aquatic system. The 
    quality change in ecological sources as the result of storm water 
    controls to reduce pollutants is not fully reflected in the present 
    benefits.
    
    D. National Economic Impact
    
        Finally, the Agency determined that the rule will have minimal 
    impacts on the economy or employment. This is because the final rule 
    regulates small MS4s and construction sites under 5 acres, not the 
    typical industrial plants or other non-construction activities that 
    could directly impact production and thus those sectors of the economy.
        Discussions with representatives within the construction industry 
    indicate that construction costs will likely be passed on to buyers, 
    thus not seriously affecting the housing industry directly. One 
    commenter argued that the rule will have a negative employment effect 
    because the builders will build fewer homes requiring less building 
    materials as a result of the declining demand induced by the cost of 
    the soil and erosion controls. EPA disagrees with this argument because 
    the cost of the controls, as the percentage of the price of a median 
    home, is negligible and will be passed on to final buyers.
        Flexibility within the rule allows MS4s to tailor the storm water 
    program requirements to their needs and financial position, minimizing 
    impacts. For sedimentation and erosion controls on construction sites, 
    the rule contemplates application of commonly used BMPs to reduce costs 
    for the construction industry. Thus, the rule attempts to use existing 
    practices to prevent pollution, which should minimize impacts on 
    States, Tribes, municipalities and the construction industry.
        Thus, EPA concludes that the effect of the rule, if any, on the 
    national economy will be minimal. The benefits of today's rule more 
    than offset any cost impacts on the national economy.
    
    IV. Regulatory Requirements
    
    A. Paperwork Reduction Act
    
        The Office of Management and Budget (OMB) has approved some of the 
    information collection requirements contained in this final rule (i.e. 
    those found in 40 CFR 122.26(g) and 123.35(b)) under the provisions of 
    the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned 
    OMB control number 2040-0211.
        The burden and costs described below are for the information 
    collection, reporting, and record keeping requirements for the three 
    year period beginning with the effective date of today's rule. 
    Additional information collection requirements for regulated small MS4s 
    and small construction sites will occur after this initial three year 
    period and will be counted in a subsequent information collection 
    requirement. The total burden of the information collection 
    requirements for the first three years of this rule is estimated at 
    56,369 hours with a corresponding cost of $2,151,305 million annually. 
    This burden and cost is for industrial facilities to complete and 
    submit the no exposure certification, for NPDES-authorized States to 
    process and review the no exposure certification, and for the NPDES-
    authorized States to develop designation criteria and assess additional 
    MS4s outside of urbanized areas. Compliance with the applicable 
    information collection requirements imposed under this rule are 
    mandatory, pursuant to CWA section 402.
        Exhibit 6 presents average annual burden and cost estimates for 
    Phase II respondents for the first three years. Burden means the total 
    time, effort, or financial resources expended by persons to generate, 
    maintain, retain, disclose or provide information to or for a Federal 
    agency. This includes the time needed to review instructions; develop, 
    acquire, install, and utilize technology and systems for the purposes 
    of collecting, validating, and verifying information, processing and 
    maintaining information, and disclosing and providing information; 
    adjust existing ways for complying with any previously applicable 
    instructions and requirements; train personnel to be able to respond to 
    a collection of information; search data sources; complete and review 
    the collection of information; and transmit or otherwise disclose the 
    information.

    Notes:
    \1\ Source: U.S. EPA, Office of Wastewater Management. Economic Analysis for the Storm Water Phase II Rule.
    \2\ The total number of potential no exposure respondents was divided by 5 to estimate an annual total. It was
      assumed that the annual number of respondents for the no exposure certification would be spread over the five
      year period the exclusion applies.
    \3\ The number of respondents in each category represents only those respondents located within the 44 NPDES-
      authorized States and Territories. The burden and cost estimates provided in this section are for the NPDES-
      authorized States in their role as the permitting authority for municipal designations and industrial no
      exposure.
    \4\ The number of respondents for this activity, 15, represents the number of NPDES-authorized States and
      Territories that must develop designation criteria and assess small MS4s located outside of an urbanized area
      for possible Phase II coverage divided by the three year ICR period.
    
        Given the requirements of today's regulation, EPA believes there 
    will be no capital startup and no operation and maintenance costs 
    associated with information collection requirements of the rule.
        The government burden associated with today's rule will impact 
    State, Tribal, and Territorial governments (NPDES-authorized 
    governmental entities) that have storm water program authority, as well 
    as the federal government (i.e., EPA), where it is the NPDES permitting 
    authority. As of March 1999, 43 States and the Virgin Islands had NPDES 
    authority.
        The annual burden imposed upon authorized governmental entities 
    (delegated States and the Virgin Islands) and the federal government 
    for the next three years is estimated to be 19,992 hours ($537,985) and 
    4,087 hours ($115,948) respectively, for a total of 24,079 hours 
    ($653,933). This estimate is based on the average time that governments 
    will expend to carry out the following activities: designate additional 
    MS4s (332.8 hours) and process and review ``no exposure'' certificates 
    from industrial dischargers (0.5 hour).
        Under the existing rule, storm water discharges from light 
    industrial activities identified under Sec. 122.26(b)(14)(xi) were 
    exempted from the permit application requirements if they were not 
    exposed to storm water. Today's rule expands the applicability of the 
    ``no exposure'' exclusion to include all industrial activity regulated 
    under Sec. 122.26(b)(14) (except category (x), construction). The ``no 
    exposure'' provision is applied through the use of a written 
    certification process, thus representing a slight reporting burden 
    increase for ``light'' industries with ``no exposure'.
        In addition to the information collection, reporting, and record 
    keeping burden for the next three years, today's rule contains 
    information collection requirements that will not begin until three 
    years or more from the effective date of today's rule. These 
    information collection requirements were not included in the 
    information collection request approved by OMB. EPA will submit these 
    burden estimates for OMB approval when it submits ICR 2040-0211 to OMB 
    for renewal in three years. The rule burdens for regulated small MS4s 
    and small construction sites that will be included in the ICR renewal 
    fall into three areas: application for an NPDES permit or submittal of 
    waiver information, record keeping of storm water management 
    activities, and submittal of reports to the permitting authority. There 
    will also be an additional burden for the permitting authority to 
    review this information.
        An agency may not conduct or sponsor, and a person is not required 
    to respond to a collection of information unless it displays a 
    currently valid OMB control number. The OMB control numbers for EPA's 
    regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15. EPA is 
    amending the table in 40 CFR Part 9 of currently approved ICR control 
    numbers issued by OMB for various regulations to list the first three 
    years of information requirements contained in this final rule.
    
    B. Executive Order 12866
    
        Under Executive Order 12866, [58 FR 51,735 (October 4, 1993)] the 
    Agency must determine whether the regulatory action is ``significant'' 
    and therefore subject to OMB review and the requirements of the 
    Executive Order. The Order defines ``significant regulatory action'' as 
    one that is likely to result in a rule that may:
        (1) have an annual effect on the economy of $100 million or more or 
    adversely affect in a material way the economy, a sector of the 
    economy, productivity, competition, jobs, the environment, public 
    health or safety, or State, local, or tribal governments or 
    communities;
        (2) create a serious inconsistency or otherwise interfere with an 
    action taken or planned by another agency;
        (3) materially alter the budgetary impact of entitlements, grants, 
    user fees, or loan programs or the rights and obligations of recipients 
    thereof; or
        (4) raise novel legal or policy issues arising out of legal 
    mandates, the President's priorities, or the principles set forth in 
    the Executive Order.
        Pursuant to the terms of Executive Order 12866, it has been 
    determined that this rule is a ``significant regulatory action''. As 
    such, this action was submitted to OMB for review. Changes made in 
    response to OMB suggestions or recommendations will be documented in 
    the public record.
    
    C. Unfunded Mandates Reform Act
    
        Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
    Law 104-4, establishes requirements for Federal agencies to assess the 
    effects of their regulatory actions on State, local, and tribal 
    governments and the private sector. Under section 202 of the UMRA, EPA 
    generally must prepare a written statement, including a cost-benefit 
    analysis, for proposed and final rules with ``Federal mandates'' that 
    may result in expenditures to State, local, and tribal governments, in 
    the aggregate, or to the private sector, of $100 million or more in any 
    one year. Before promulgating an EPA rule for which a
    
    [[Page 68797]]
    
    written statement is needed, section 205 of the UMRA generally requires 
    EPA to identify and consider a reasonable number of regulatory 
    alternatives and adopt the least costly, most cost-effective or least 
    burdensome alternative that achieves the objectives of the rule. The 
    provisions of section 205 do not apply when they are inconsistent with 
    applicable law. Moreover, section 205 allows EPA to adopt an 
    alternative other than the least costly, most cost-effective or least 
    burdensome alternative if the Administrator publishes with the final 
    rule an explanation why that alternative was not adopted.
        EPA has determined that today's rule contains a Federal mandate 
    that may result in expenditures of $100 million or more in any one year 
    for both State, local, and tribal governments, in the aggregate, and 
    the private sector. Accordingly, EPA has prepared under section 202 of 
    the UMRA a written statement which is summarized below.
    1. Summary of UMRA Section 202 Written Statement
        EPA promulgates today's storm water regulation pursuant to the 
    specific mandate of Clean Water Act section 402(p)(6), as well as 
    sections 301, 308, 402, and 501. (33 U.S.C. sections 1342(p)(6), 1311, 
    1318, 1342, 1361.) Section 402(p)(6) of the CWA requires that EPA 
    designate sources to be regulated to protect water quality and 
    establish a comprehensive program to regulate those sources.
        In the Economic Analysis of the Final Phase II Rule (EA), EPA 
    describes the qualitative and monetized benefits associated with 
    today's rule and then compares the monetized benefits with the 
    estimated costs for the rule. EPA developed detailed estimates of the 
    costs and benefits of complying with each of the incremental 
    requirements imposed by the rule. These estimates, including 
    descriptions of the methodology and assumptions used, are described in 
    detail in the EA. The Agency used two approaches, a national water 
    quality model and national water quality assessment, to estimate the 
    potential benefits of the rule. Both approaches show that the benefits 
    are likely to exceed costs. Exhibit 3 in section III of this preamble 
    summarizes the costs and benefits associated with the basic elements of 
    today's rule.
        There are additional benefits to storm water control that cannot be 
    quantified or monetized. Thus, the current estimate of monetized 
    benefits may understate the true value of storm water controls because 
    it omits many ways by which society is likely to benefit from reduced 
    storm water pollution, such as improved aesthetic quality of waters, 
    benefits to wildlife and to threatened and endangered species, cultural 
    values, and biodiversity benefits.
        Several commenters asserted that today's rule is an unfunded 
    mandate and that, without funding, the monitoring of the already 
    existing pollution control programs would suffer. In section II.D.3 of 
    the preamble, EPA lists some of the programs that EPA anticipates may 
    provide funds to help develop and, in limited circumstances, implement 
    storm water management programs.
        In the EA, EPA reviewed the expected effect of today's rule on the 
    national economy. The Agency determined that the rule will have minimal 
    impacts on the economy or employment. This is because the final rule 
    regulates small MS4s and construction sites under 5 acres, not the 
    typical industrial plants or other non-construction activities that 
    could directly impact production and thus those sectors of the economy.
        Discussions with representatives within the construction industry 
    indicate that construction costs will likely be passed on to buyers, 
    thus not seriously affecting the housing industry directly. Flexibility 
    within the rule allows MS4s to tailor the storm water program 
    requirements to their needs and financial position, minimizing impacts. 
    For sedimentation and erosion controls on construction sites, the rule 
    contemplates application of commonly used BMPs to reduce costs for the 
    construction industry. Thus, the rule attempts to use existing 
    practices to prevent pollution, which should minimize impacts on 
    States, Tribes, municipalities and the construction industry.
        Thus, EPA concludes that the effect of the rule, if any, on the 
    national economy would be minimal. The benefits of today's rule more 
    than offset any cost impacts on the national economy.
        Consistent with the intergovernmental consultation provisions of 
    section 204 of the UMRA and Executive Order 12875, ``Enhancing the 
    Intergovernmental Partnership,'' EPA consulted with the governmental 
    entities affected by this rule.
        First, EPA provided States, Tribal and local governments with the 
    opportunity to comment on draft alternative approaches for the proposed 
    rule through publishing a notice requesting information and public 
    comment in the Federal Register on September 9, 1992 (57 FR 41344). 
    This notice presented a full range of regulatory alternatives. At that 
    time, EPA received more than 130 comments, including approximately 43 
    percent from municipalities and 24 percent from State or Federal 
    agencies. These comments were the genesis of many of the provisions in 
    the today's rule, including reliance on the NPDES program framework 
    (including general permits), providing State and local governments 
    flexibility in selecting additional sources requiring regulation, and 
    focusing on high priority polluters. These comments helped to focus on 
    pollution prevention, watershed-based concerns and BMPs. They also led 
    to certain exemptions for facilities that do not pollute national 
    waters.
        In early 1993, EPA, in conjunction with the Rensselaerville 
    Institute, held public and expert meetings to assist in developing and 
    analyzing options for identifying unregulated storm water sources and 
    possible controls. These meetings provided participants an additional 
    opportunity to provide input into the CWA section 402(p)(6) program 
    development process. The final rule addresses several of the key 
    concerns identified in these groups, including provisions that provide 
    flexibility to the States to select sources to be controlled and types 
    of permits to be issued, and flexibility to MS4s in selecting BMPs.
        EPA also conducted outreach with representatives of small entities, 
    including small government representatives, in conjunction with the 
    convening of a Small Business Advocacy Review Panel under SBREFA which 
    is discussed in section IV.E. of the preamble.
        In addition, EPA established the Urban Wet Weather Flows Advisory 
    Committee under the Federal Advisory Committee Act (FACA). The Urban 
    Wet Weather Flows Advisory Committee, in turn established the Storm 
    Water Phase II Subcommittee. Consistent with FACA, the membership of 
    the Committee and the Storm Water Phase II Subcommittee was balanced 
    among EPA's various outside stakeholder interests, including 
    representatives from State governments, municipal governments (both 
    elected officials and appointed officials) and Tribal governments, as 
    well as industrial and commercial sectors, agriculture, environmental 
    and public interest groups.
        In general, municipal and Tribal government representatives 
    supported the NPDES approach in today's rule for the following reasons: 
    It will be uniformly applied on a nationwide basis; it provides 
    flexibility to allow incorporation of State and local programs; it 
    resolves the problem of donut holes that cause water quality impacts in 
    urbanized areas; and it allows co-permitting of small regulated
    
    [[Page 68798]]
    
    MS4s with those regulated under the existing storm water program.
        In contrast, State representatives sought alternative approaches 
    for State implementation of the storm water program for Phase II 
    sources. State representatives asserted that a non-NPDES alternative 
    approach best facilitated watershed management and avoided duplication 
    and overlapping regulations. These representatives pointed out that 
    there are a variety of State programs--not based on the CWA--
    implementing effective storm water controls, and that EPA should 
    provide incentives for their implementation and improvement in 
    performance. EPA continues to believe that an NPDES approach is the 
    best approach in order to adequately protect water quality. However, 
    EPA has worked with States on an alternative approach that provides 
    flexibility within the NPDES framework. The final rule allows States 
    with a watershed permitting approach to phase in permit coverage for 
    MS4s in jurisdictions with a population less than 10,000 and provides 
    two waivers from coverage for small MS4s. This issue is discussed in 
    section II.C of the preamble, Program Framework: NPDES Approach.
        Some municipal governments objected that the rule's minimum 
    measures for small MS4s violate the Tenth Amendment insofar as they 
    require the operators of MS4s to regulate third parties according to 
    the ``minimum measures'' for municipal storm water management programs. 
    EPA disagrees that today's rule is inconsistent with Tenth Amendment 
    principles. Permits issued under today's rule will not compel political 
    subdivisions of States to regulate in their sovereign capacities, but 
    rather to effectively control discharges out of their storm sewer 
    systems in their owner/operator capacities. For MS4s that do not accept 
    this ``default'' minimum measures-based approach (to control discharges 
    out of the storm sewer system by exercising local powers to control 
    discharges into the storm sewer system), today's rule allows for 
    alternative permits through individual permit applications. EPA made 
    revisions to the rule to allow regulated small MS4s to opt out of the 
    minimum measures approach and instead apply for an individual permit. 
    This issue is discussed in section II.H.3.c.iii of the preamble, 
    Alternative Permit Option/Tenth Amendment.
    2. Selection of the Least Costly, Most Cost-Effective or Least 
    Burdensome Alternative That Achieves the Objectives of the Statute
        Today's rule evolved over time and incorporated aspects of 
    alternatives that responded to concerns presented by the various 
    stakeholders. A primary characteristic of today's rule is the 
    flexibility it offers both the permitting authority and the regulated 
    sources (small MS4s and small construction sites), by the use of 
    general permits, implementation of BMPs suited to specific locations, 
    and allowing MS4s to develop their own program goals.
        In the administrative record supporting the proposed rule, EPA 
    estimated ranges of costs associated with six different options, 
    including a no action option, the proposed option, and four other 
    options that considered various combinations of the following: Covering 
    all the unregulated construction sites below 5 acres, all small MS4s, 
    certain industrial and commercial activities, and all point sources. 
    EPA developed detailed cost estimates for the incremental requirements 
    imposed under the final regulation, and for each of the alternatives, 
    and applied these estimates to the remaining unregulated point sources 
    of storm water. The Agency compared the estimated annual range of costs 
    imposed under today's rule and other major options considered. The 
    range of values for each option included the costs for compliance, 
    including paperwork requirements for the operators of small 
    construction sites, industrial facilities, and MS4s and administrative 
    costs for State and Federal NPDES permitting authorities.
        Today's rule reflects the least costly option that achieves the 
    objectives of the statute, thus meeting the requirements of section 
    205. EPA did not consider ``no regulation'' to be an ``option'' because 
    it would not achieve the objectives of CWA section 402(p)(6). A portion 
    of currently unregulated point sources of storm water need to reduce 
    pollutants to protect water quality.
        Today's rule is estimated to range in cost from $847.6 million to 
    $981.3 million annually, although the cost estimate for the proposed 
    rule was reported as a range of $138 to $869 million annually. That 
    range reflected a unit cost range for the municipal minimum measures 
    and a cost range per construction site for soil erosion control. EPA 
    has since revised its cost analysis to allow it to report the current 
    estimate, which is toward the high end of the original cost range. The 
    four other regulatory options considered at proposal involved higher 
    regulatory costs and, therefore, were not selected. These four options 
    and their estimated costs are as follows:
        (1) An option based on the August 7, 1995 direct final rule was 
    estimated to cost between $2.2 billion and $78.9 billion per year.
        (2) A ``Plan B'' option was estimated to cost between $0.6 billion 
    and $3.2 billion per year.
        (3) An option based on the September 30, 1996 draft proposed rule 
    was estimated to cost between $0.2 billion and $3.7 billion per year.
        (4) An option based on the February 13, 1997 draft proposed rule, 
    was estimated to cost between $0.2 billion and $3.5 billion.
        There are three reasons why the costs for these four options 
    exceeded the estimated cost range for the proposed rule. The first two 
    options regulated substantially more municipal governments. The first, 
    third, and fourth options required industrial facilities to apply for 
    permits. Finally, the first three options applied permit requirements 
    to construction sites below 1 acre. Consequently, these options would 
    be more costly than today's rule even with the revised analysis methods 
    used to estimate costs.
    3. Effects on Small Governments
        Before EPA establishes any regulatory requirements that may 
    significantly or uniquely affect small governments, including tribal 
    governments, it must have developed under section 203 of the UMRA a 
    small government agency plan. The plan must provide for notifying 
    potentially affected small governments, enabling officials of affected 
    small governments to have meaningful and timely input in the 
    development of EPA regulatory proposals with significant Federal 
    intergovernmental mandates, and informing, educating, and advising 
    small governments on compliance with the regulatory requirements. EPA 
    has determined that this rule contains no regulatory requirements that 
    might significantly or uniquely affect small governments. Although 
    today's rule expands the NPDES program (with modifications) to certain 
    MS4s serving populations below 100,000 and although many MS4s are owned 
    by small governments, EPA does not believe today's rule significantly 
    or uniquely affects small governments. As explained in section IV.E. of 
    the preamble, EPA today certifies that the rule will not have a 
    significant impact on small governmental jurisdictions. In addition, 
    the rule will not have a unique impact on small governments because the 
    rule will affect small governments in
    
    [[Page 68799]]
    
    to the same extent as (or to a lesser extent than) larger governments 
    that are already covered by the existing storm water rules. Thus, 
    today's rule is not subject to the requirements of section 203 of UMRA.
        Notwithstanding this finding, in developing today's rule, EPA 
    provided notice of the requirements to potentially affected small 
    governments; enabled officials of affected small governments to provide 
    meaningful and timely input in the development of regulatory proposals; 
    and informed, educated and advised small governments on compliance with 
    the requirements.
        Concerning notice, EPA provided States, local, and Tribal 
    governments with the opportunity to comment on alternative approaches 
    for an early draft of the proposed rule by publishing a notice 
    requesting information and public comment in the Federal Register on 
    September 9, 1992 (57 FR 41344). This notice presented a full range of 
    regulatory alternatives. At that time, EPA received more than 130 
    comments, including approximately 43 percent from municipalities and 24 
    percent from State or Federal agencies.
        The Agency also provided, through the SBREFA panel process and the 
    FACA process, the opportunity for elected officials of small 
    governments (and their representatives) to meaningfully participate in 
    the development of the rule. Through such participation and exchange, 
    EPA not only notified potentially affected small governments of 
    requirements of the developing rule, but also allowed officials of 
    affected small governments to have meaningful and timely input into the 
    development of regulatory proposals.
        In addition to involving municipalities in the development of the 
    rule, EPA also continues to inform, educate, and advise small 
    governments on compliance with the requirements of today's rule. For 
    example, EPA supported 10 workshops, presented by the American Public 
    Works Association from September 1998 through May 1999, designed to 
    educate local governments on the implementation of the rule. The 
    workshop curriculum included information on a variety of key issues 
    such as anticipated regulatory requirements, agency reporting, best 
    management practices, construction site controls, post construction 
    management for new and redeveloped sites, public education and public 
    involvement strategies, detection and control of illicit discharges, 
    and good housekeeping practices. Moreover, EPA has prepared a series of 
    fact sheets, available on the EPA website at www.epa.gov/owm/sw/
    toolbox, that explains the rule in detail.
        Finally, to assist small governments in implementing the Phase II 
    program, EPA is committed to the following: (1) developing a tool box 
    of implementation strategies; (2) providing written technical 
    assistance, including guidance on developing BMPs and measurable goals; 
    and (3) compiling a comprehensive evaluation of the NPDES municipal 
    storm water Phase II program over the next 13 years.
    
    D. Executive Order 13132
    
        Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
    10, 1999), requires EPA to develop an accountable process to ensure 
    ``meaningful and timely input by State and local officials in the 
    development of regulatory policies that have federalism implications.'' 
    ``Policies that have federalism implications'' is defined in the 
    Executive Order to include regulations that have ``substantial direct 
    effects on the States, on the relationship between the national 
    government and the States, or on the distribution of power and 
    responsibilities among the various levels of government.'' Under 
    Executive Order 13132, EPA may not issue a regulation that has 
    federalism implications, that imposes substantial direct compliance 
    costs, and that is not required by statute, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by State and local governments, or EPA consults with 
    State and local officials early in the process of developing the 
    proposed regulation. EPA also may not issue a regulation that has 
    federalism implications and that preempts State law unless the Agency 
    consults with State and local officials early in the process of 
    developing the proposed regulation.
        If EPA complies by consulting, Executive Order 13132 requires EPA 
    to provide to the Office of Management and Budget (OMB), in a 
    separately identified section of the preamble to the rule, a federalism 
    summary impact statement (FSIS). The FSIS must include a description of 
    the extent of EPA's prior consultation with State and local officials, 
    a summary of the nature of their concerns and the agency's position 
    supporting the need to issue the regulation, and a statement of the 
    extent to which the concerns of State and local officials have been 
    met. For final rules subject to Executive Order 13132, EPA also must 
    submit to OMB a statement from the agency's Federalism Official 
    certifying that EPA has fulfilled the Executive Order's requirements.
        EPA has concluded that this final rule may have federalism 
    implications. As discussed above in section IV.C., the rule contains a 
    Federal mandate that may result in the expenditure by State, local and 
    tribal governments, in the aggregate, of $100 million or more in any 
    one year. Accordingly, the rule may have substantial direct effects on 
    the States, on the relationship between the national government and the 
    States, or on the distribution of power and responsibilities among the 
    various levels of government, as specified in Executive Order 13132. 
    Moreover, the rule will impose substantial direct compliance costs on 
    State or local governments. Accordingly, EPA provides the following 
    FSIS under section 6(b) of Executive Order 13132.
    1. Description of the Extent of the Agency's Prior Consultation with 
    State and Local Governments
        Although this rule was proposed long before the November 2, 1999 
    effective date of Executive Order 13132, EPA consulted extensively with 
    affected State and local governments pursuant to the intergovernmental 
    consultation provisions of Executive Order 12875, ``Enhancing the 
    Intergovernmental Partnership'' (now revoked by Executive Order 13132) 
    and section 204 of UMRA.
        First, EPA provided State and local governments the opportunity to 
    comment on draft alternative approaches for the proposed rule through 
    publishing a notice requesting information and public comment in the 
    Federal Register on September 9, 1992 (57 FR 41344). This notice 
    presented a full range of regulatory alternatives. At that time, EPA 
    received more than 130 comments, including approximately 43 percent 
    from municipalities and 24 percent from State or Federal agencies. 
    These comments were the genesis of many of the provisions in the 
    today's rule, including reliance on the NPDES program framework 
    (including general permits), providing State and local governments 
    flexibility in selecting additional sources requiring regulation, and 
    focusing on high priority polluters. These comments helped to focus on 
    pollution prevention, watershed-based concerns and BMPs. They also led 
    to certain exemptions for facilities that do not pollute national 
    waters.
        In early 1993, EPA, in conjunction with the Rensselaerville 
    Institute, held public and expert meetings to assist in developing and 
    analyzing options for identifying unregulated storm water sources and 
    possible controls. These meetings provided participants an additional 
    opportunity to provide input into the CWA section 402(p)(6) program
    
    [[Page 68800]]
    
    development process. The final rule addresses several of the key 
    concerns identified in these groups, including provisions that provide 
    flexibility to the States to select sources to be controlled and types 
    of permits to be issued, and flexibility to MS4s in selecting BMPs.
        EPA also conducted outreach with representatives of small entities, 
    including small governments, in conjunction with the convening of a 
    Small Business Advocacy Review Panel under SBREFA which is discussed in 
    section III.F. of the preamble.
        In addition, EPA established the Urban Wet Weather Flows Advisory 
    Committee (FACA), which in turn established the Storm Water Phase II 
    Subcommittee. Consistent with the Federal Advisory Committee Act, the 
    membership of the Committee and the Storm Water Phase II Subcommittee 
    was balanced among EPA's various outside stakeholder interests, 
    including representatives from State governments, municipal governments 
    (both elected officials and appointed officials) and Tribal 
    governments, as well as industrial and commercial sectors, agriculture, 
    environmental and public interest groups.
    2. Summary of Nature of State and Local Government Concerns, and 
    Statement of the Extent to Which Those Concerns Have Been Met
        In general, municipal government representatives supported the 
    NPDES approach in today's rule for the following reasons: it will be 
    uniformly applied on a nationwide basis; it provides flexibility to 
    allow incorporation of State and local programs; it resolves the 
    problem of donut holes that cause water quality impacts in urbanized 
    areas; and it allows co-permitting of small regulated MS4s with those 
    regulated under the existing storm water program.
        In contrast, State representatives sought alternative approaches 
    for State implementation of the storm water program for Phase II 
    sources. State representatives asserted that a non-NPDES alternative 
    approach best facilitated watershed management and avoided duplication 
    and overlapping regulations. These representatives pointed out that 
    there are a variety of State programs--not based on the CWA--
    implementing effective storm water controls, and that EPA should 
    provide incentives for their implementation and improvement in 
    performance. EPA continues to believe that an NPDES approach is the 
    best approach in order to adequately protect water quality. However, 
    EPA has worked with States on an alternative approach that provides 
    flexibility within the NPDES framework. The final rule allows States 
    with a watershed permitting approach to phase in permit coverage for 
    MS4s in jurisdictions with a population less than 10,000 and provides 
    two waivers from coverage for small MS4s. This issue is discussed in 
    section II.C of the preamble, Program Framework: NPDES Approach.
        Some municipal governments objected that the rule's minimum 
    measures for small MS4s violate the Tenth Amendment insofar as they 
    require the operators of MS4s to regulate third parties according to 
    the ``minimum measures'' for municipal storm water management programs. 
    EPA disagrees that today's rule is inconsistent with Tenth Amendment 
    principles. Permits issued under today's rule will not compel political 
    subdivisions of States to regulate in their sovereign capacities, but 
    rather to effectively control discharges out of their storm sewer 
    systems in their owner/operator capacities. For MS4s that do not accept 
    this ``default'' minimum measures-based approach (to control discharges 
    out of the storm sewer system by exercising local powers to control 
    discharges into the storm sewer system), today's rule allows for 
    alternative permits through individual permit applications. EPA made 
    revisions to the rule to allow regulated small MS4s to opt out of the 
    minimum measures approach and instead apply for an individual permit. 
    This issue is discussed in section II.H.3.c.iii of the preamble, 
    Alternative Permit Option/Tenth Amendment.
    3. Summary of the Agency's Position Supporting the Need To Issue the 
    Regulation
        As discussed more fully in section I.B. above, today's rule is 
    needed because uncontrolled storm water discharges from areas of urban 
    development and construction activity have been shown to have negative 
    impacts on receiving waters by changing the physical, biological, and 
    chemical composition of the water, resulting in an unhealthy 
    environment for aquatic organisms, wildlife, and people. As discussed 
    in section II.C., the NPDES approach in today's rule is needed to 
    ensure uniform application on a nationwide basis, to provide 
    flexibility to allow incorporation of State and local programs, to 
    resolve the problem of donut holes that cause water quality impacts in 
    urbanized areas, and to allow co-permitting of small regulated MS4s 
    with those regulated under the existing storm water program.
        The draft final rule was transmitted to OMB on July 6, 1999. 
    Because transmittal occurred before the November 2, 1999 effective date 
    of Executive Order 13132, certification under section 8 of the 
    Executive Order is not required.
    
    E. Regulatory Flexibility Act (RFA), as amended by the Small Business 
    Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et 
    seq.
    
        The RFA generally requires an Agency to prepare a regulatory 
    flexibility analysis of any rule subject to notice and comment 
    rulemaking requirements under the Administrative Procedure Act or any 
    other statute unless the agency certifies that the rule will not have a 
    significant economic impact on a substantial number of small entities. 
    Small entities include small businesses, small organizations, and small 
    governmental jurisdictions.
        For purposes of assessing the impact of today's rule on small 
    entities, small entity is defined as: (1) a building contractor (SIC 
    15) with up to $17.0 million in annual revenue; (2) a small 
    governmental jurisdiction that is a government of a city, county, town, 
    school district, or special district with a population of less than 
    50,000; and (3) a small organization that is any not-for-profit 
    enterprise which is independently owned and operated and is not 
    dominant in its field.
        After considering the economic impacts of today's final rule on 
    small entities, I certify that this action will not have a significant 
    economic impact on a substantial number of small entities.
        Although this final rule will not have a significant economic 
    impact on a substantial number of small entities, EPA nonetheless has 
    tried to reduce the impact of this rule on small entities.
        For purposes of evaluating the economic impact of this rule on 
    small governmental jurisdictions, EPA compared annual compliance costs 
    with annual government revenues obtained from the 1992 Census of 
    Governments, using state-specific estimates of annual revenue per 
    capita for municipalities in three population size categories (fewer 
    than 10,000, 10,000-25,000, and 25,000-50,000).
        In order to estimate the annual compliance cost for small 
    governmental jurisdictions, EPA used the mean variable municipal cost 
    of $8.93 per household as calculated in a 1998 study of 121 
    municipalities conducted by the national Association of Flood and 
    Stormwater Management Agencies (NAFSMA). In addition, EPA used the 
    estimated fixed administrative costs of $1,545 per municipality for 
    reporting,
    
    [[Page 68801]]
    
    recordkeeping, and application requirements for today's rule.
        In evaluating the economic impact of this rule on small 
    governmental jurisdictions, EPA determined that compliance costs 
    represent more than 1 percent of estimated revenues for only 10 percent 
    of small governments and more than 3 percent of the revenue for 0.7 
    percent of these entities. In both absolute and relative terms, EPA 
    does not consider this a significant economic impact on a substantial 
    number of small entities.
        EPA normally uses the ``sales test'' for determining the economic 
    impact on small businesses. Under a sales test, annual compliance costs 
    are compared with the small business's total annual sales. However, the 
    direct application of the sales test is not suitable in this case, 
    because of the uncertainty associated with estimating the number of 
    units an ``average'' developer/contractor develops or builds in a 
    typical year. For this rule, EPA has approximated the sales test by 
    estimating compliance costs for three sizes of construction sites and 
    comparing them with a representative sale price for three building 
    categories. Although EPA's analysis is not exactly a ``sales test,'' it 
    is similar to the sales test, producing comparable results.
        For small building contractors, EPA estimated administrative 
    compliance costs of $870 per site for applying for coverage, reporting, 
    record keeping, monitoring and preparing a storm water pollution 
    prevention plan. EPA estimated compliance costs for installing soil and 
    erosion controls as ranging from $1,206 to $8,709 per site. EPA 
    compliance cost estimates are based on 27 theoretical model 
    construction sites designed to mimic the mostly likely used best 
    management practices around the country.
        In evaluating the economic impact on small building contractors, 
    EPA divided the revised compliance costs per construction start by the 
    appropriate homes-to-site ratio for each of the three sizes of 
    construction sites. The average compliance cost per home ranges from 
    approximately $450 to $650. EPA concluded that compliance costs are 
    roughly 0.22 to 0.43 percent of both the mean, $181,300, and median, 
    $151,000, sale price of a home.
        The absence of data to specifically assess annual compliance costs 
    for building contractors as a percentage of annual sales (i.e., a very 
    direct estimate of the impact on potentially affected small businesses) 
    led EPA to perform additional market analysis to examine the ability of 
    potentially affected firms to pass along regulatory costs to buyers for 
    single-family homes constructed subject to today's rule. If the small 
    building contractors covered by the rule are able to pass on the costs 
    of compliance, either completely or partially, to their purchasers, 
    then the rule's impact on these small business entities is 
    significantly reduced. The market analysis shows that demand for homes 
    is not overly sensitive to small changes in price, therefore builders 
    should be able to pass on at least a significant fraction of the 
    compliance costs to buyers.
        EPA also assessed the effect of the building contractors' costs on 
    average monthly mortgage rates and on the demand for new homes. Based 
    on that screening analysis, EPA concludes that the costs to building 
    contractors, and the potential changes in housing prices and monthly 
    mortgage payments for single-family home buyers, are not expected to 
    have a significant impact on the market for single-family houses. In 
    both absolute and relative terms, EPA does not consider this a 
    significant economic impact on a substantial number of small entities.
        EPA also certified this rule at proposal. Even though the Agency 
    was not required to, we convened a Small Business Advocacy Review Panel 
    (``Panel'') in June 1997. A number of small entity representatives had 
    already been actively involved with EPA through the FACA process, and 
    were, therefore, broadly knowledgeable about the development of the 
    proposed and final rules. Prior to convening the Panel, EPA consulted 
    with the Small Business Administration to identify a group of small 
    entity representatives to advise the Panel. The Agency distributed a 
    briefing package describing its preliminary analysis under the RFA to 
    the small entity representatives (as well as to representatives from 
    OMB and SBA) and conducted two telephone conference calls and an all-
    day meeting at EPA Headquarters in May of 1997 with small entity 
    representatives. With this preliminary work complete, in June 1997, EPA 
    formally convened the SBREFA Panel, comprising representatives from 
    OMB, SBA, EPA's Office of Water and EPA's Small Business Advocacy 
    Chair. The Panel received written comments from small entity 
    representatives based on their involvement in the earlier meetings, and 
    invited additional comments.
        Consistent with requirements of the RFA, the Panel evaluated the 
    assembled materials and small-entity comments on issues related to: (1) 
    a description and the number of small entities that would be regulated; 
    (2) a description of the projected record keeping, reporting and other 
    compliance requirements applicable to small entities; (3) 
    identification of other Federal rules that may duplicate, overlap, or 
    conflict with the proposal to the final rule; and (4) regulatory 
    alternatives that would minimize any significant economic impact of the 
    rule on small entities while accomplishing the stated objectives of the 
    CWA section 402(p)(6).
        On August 7, 1997, the Panel provided a Final Report (hereinafter, 
    ``Report'') to the EPA Administrator. A copy of the Report is included 
    in the docket for the rule. The Panel acknowledged and commended EPA's 
    efforts to work with stakeholders, including small entities, through 
    the FACA process. The SBREFA Panel stated that, because of EPA's 
    extensive outreach and responsiveness in addressing stakeholder 
    concerns, commenters during the SBREFA process raised fewer concerns 
    than might otherwise have been expected. Based on the advice and 
    recommendations of the Panel, today's rule includes a number of 
    provisions designed to minimize any significant impact on small 
    entities. (See Appendix 5).
    
    F. National Technology Transfer And Advancement Act
    
        Section 12(d) of the National Technology Transfer and Advancement 
    Act of 1995 (``NTTAA''), Public Law 104-113, section 12(d) (15 U.S.C. 
    272 note) directs EPA to use voluntary consensus standards in its 
    regulatory activities unless to do so would be inconsistent with 
    applicable law or otherwise impractical. Voluntary consensus standards 
    are technical standards (e.g., materials specifications, test methods, 
    sampling procedures, and business practices) that are developed or 
    adopted by voluntary consensus standard bodies. The NTTAA directs EPA 
    to provide Congress, through OMB, explanations when the Agency decides 
    not to use available and applicable voluntary consensus standards.
        This action does not mandate the use of any particular technical 
    standards, although in designing appropriate BMPs regulated small MS4s 
    and small construction sites are encouraged to use any voluntary 
    consensus standards that may be applicable and appropriate. Because no 
    specific technical standards are included in the rule, section 12(d) of 
    the NTTAA is not applicable.
    
    G. Executive Order 13045
    
        Executive Order 13045: ``Protection of Children from Environmental 
    Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
    to any rule that: (1) Is determined to be ``economically
    
    [[Page 68802]]
    
    significant'' as defined under E.O. 12866, and (2) concerns an 
    environmental health or safety risk that EPA has reason to believe may 
    have a disproportionate effect on children. If the regulatory action 
    meets both criteria, the Agency must evaluate the environmental health 
    or safety effects of the planned rule on children, and explain why the 
    planned regulation is preferable to other potentially effective and 
    reasonably feasible alternatives considered by the Agency.
        This final rule is not subject to E.O. 13045 because it does not 
    concern an environmental health or safety risk that may have a 
    disproportionate effect on children. The rule expands the scope of the 
    existing NPDES permitting program to require small municipalities and 
    small construction sites to regulate their storm water discharges. The 
    rule does not itself, however, establish standards or criteria that 
    would be included in permits for those sources. Such standards or 
    criteria will be developed through other actions, for example, in the 
    establishment of water quality standards or subsequently in the 
    issuance of permits themselves. As such, today's action does not 
    concern an environmental health or safety risk that may have a 
    disproportionate effect on children. To the extent it does address a 
    risk that may have a disproportionate effect on children, expanding the 
    scope of the permitting program will have a corresponding 
    disproportionate benefit to children to protect them from such risk.
    
    H. Executive Order 13084
    
        Under Executive Order 13084, EPA may not issue a regulation that is 
    not required by statute, that significantly or uniquely affects the 
    communities of Indian tribal governments, and that imposes substantial 
    direct compliance costs on those communities, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by the Tribal governments, or EPA consults with those 
    governments. If EPA complies by consulting, Executive Order 13084 
    requires EPA to provide to the Office of Management and Budget, in a 
    separately identified section of the preamble to the rule, a 
    description of the extent of EPA's prior consultation with 
    representatives of affected Tribal governments, a summary of the nature 
    of their concerns, and a statement supporting the need to issue the 
    regulation. In addition, Executive Order 13084 requires EPA to develop 
    an effective process permitting elected officials and other 
    representatives of Indian Tribal governments ``to provide meaningful 
    and timely input in the development of regulatory policies on matters 
    that significantly or uniquely affect their communities.''
        Today's rule does not significantly or uniquely affect the 
    communities of Indian Tribal governments. Even though the Agency is not 
    required to address Tribes under the Regulatory Flexibility Act, EPA 
    used the same revenue test that was used for municipalities to assess 
    the impact of the rule on communities of Tribal governments and 
    determine that they will not be significantly affected. In addition, 
    the rule will not have a unique impact on the communities of Tribal 
    governments because small municipal governments are also covered by 
    this rule and larger municipal governments are already covered by the 
    existing storm water rules. Accordingly, the requirements of section 
    3(b) of Executive Order 13084 do not apply to this rule.
    
    I. Congressional Review Act
    
        The Congressional Review Act, 5 U.S.C. section 801 et seq., as 
    added by the Small Business Regulatory Enforcement Fairness Act of 
    1996, generally provides that before a rule may take effect, the agency 
    promulgating the rule must submit a rule report, which includes a copy 
    of the rule, to each House of the Congress and the Comptroller General 
    of the United States. EPA will submit a report containing this rule and 
    other required information to the U.S. Senate, the U.S. House of 
    Representatives, and the Comptroller General of the United States prior 
    to publication of the rule in the Federal Register. A major rule cannot 
    take effect until 60 days after it is published in the Federal 
    Register. This rule is a ``major rule'' as defined by 5 U.S.C. 804(2). 
    This rule will be effective on February 7, 2000.

    Please Note
    
        ``(pt.)'' indicates that the American Indian Area (AIA) listed 
    is only partially located within the referenced urbanized area.
        The first line under ``American Indian Area'' is the name of the 
    federally-recognized reservation/colony/rancheria or trust land as 
    it appears in the Bureau of the Census data. After this first line, 
    the names of the tribes included in the AIA are listed as they 
    appear in the Bureau of Indian Affairs' list of Federally Recognized 
    Indian Tribes. [Federal Register: Nov. 13, 1996, Vol. 66, No. 220, 
    pgs. 58211-58216]
        ``TJSAs'' are Tribal Jurisdiction Statistical Areas in Oklahoma 
    that are defined in conjunction with the federally-recognized tribes 
    in Oklahoma who have definite land areas under their jurisdiction, 
    but do not have reservation status.
        ``(Phase I)'' indicates that the referenced urbanized area 
    includes a medium or large MS4 currently regulated under the 
    existing NPDES storm water program (i.e., Phase I). Any Tribally 
    operated MS4 within these such urban areas would not automatically 
    have been covered under Phase I, however.

    Appendix 5 to Preamble--Regulatory Flexibility for Small Entities
    
    A. Regulatory Flexibility for Small Municipal Storm Sewer Systems 
    (MS4s)
    
    Different Compliance, Reporting, or Timetables That Are Responsive 
    to Resources of Small Entities
    
        NPDES permitting authorities can issue general permits instead 
    of requiring individual permits. This flexibility avoids the high 
    application costs and administrative burden associated with 
    individual permits.
        NPDES permitting authorities can specify a time period of up to 
    five years for small MS4s to fully develop and implement their 
    program
        Analytic monitoring is not required.
        After the first permit term and subsequent permit terms, 
    submittal of a summary report is only required in years two and four 
    (Phase I municipalities are currently required to submit a detailed 
    report each year).
        A brief reporting format is encouraged to facilitate compiling 
    and analyzing data from submitted reports. EPA intends to develop a 
    model form for this purpose.
        NPDES Permitting Authorities can phase in permit coverage for 
    small MS4s serving jurisdictions with a population under 10,000 on a 
    schedule consistent with a State watershed permitting approach.
    
    Clarifying, Consolidating, or Simplifying Compliance and Reporting 
    Requirements
    
        The rule avoids duplication in permit requirements by allowing 
    NPDES permitting authorities to include permit conditions that 
    direct an MS4 to follow the requirements of a qualifying local 
    program rather than the requirements of a minimum measure. 
    Compliance with these programs is considered compliance with the 
    NPDES general permit.
        The rule allows NPDES permitting authorities to recognize 
    existing responsibilities among different municipal entities to 
    satisfy obligations for the minimum control measures.
        A further alternative allows a small MS4 to satisfy its NPDES 
    permit obligations if another governmental entity is already 
    implementing a minimum control measure in the jurisdiction of the 
    small MS4. The following conditions must be met:
        1. The other entity is implementing the control measure,
        2. The particular control measure (or component thereof) is at 
    least as stringent as the corrersponding NPDES permit requirement, 
    and
        3. The other entity agrees to implement the control measure on 
    your behalf.
        The rule allows a covered small MS4 to ``piggy-back'' on to the 
    storm water management program of an adjoining Phase I MS4. A small 
    MS4 is waived from the application requirements of 
    Sec. 122.26(d)(1)(iii), (iv) and (d)(2)(iii) [discharge 
    characterization] and may satisfy the requirements of 
    Sec. 122.26(d)(1)(v) and (d)(2)(iv) [identifying a management plan] 
    by referencing the adjoining Phase I MS4's storm water management 
    plan.
        The rule accommodates the use of the watershed approach through 
    NPDES general permits that could be issued on a watershed basis. The 
    small MS4 can develop measures that are tailored to meet their 
    watershed requirements. The small MS4's storm water management 
    program can tie into watershed-wide plans.
    
    Performance Rather Than Design Standards for Small Entities
    
        Small governmental jurisdictions whose MS4s are covered by this 
    rule are allowed to choose the best management practices (BMPs) to 
    be implemented and the measurable goals for each of the minimum 
    control measures:
        1. Public education and outreach on storm water impacts
        2. Public Involvement/Participation
        3. Illicit discharge detection and elimination
    
    [[Page 68812]]
    
        4. Construction site storm water runoff control
        5. Post-construction storm water management in new development 
    and redevelopment
        6. Pollution prevention/good housekeeping for municipal 
    operations
        EPA will provide guidance and recommend, but not mandate, 
    certain BMPs for some of the minimum control measures listed above. 
    States can provide guidance to supplement or supplant EPA guidance.
        Small MS4s can identify the measurable goals for each of the 
    minimum control measures listed above. In their reports to the NPDES 
    permitting authority, the small MS4s must evaluate their progress 
    towards achievement of their identified measurable goals.
    
    Waivers for Small Entities From Coverage
    
        The rule allows permitting authorities to waive from coverage 
    MS4s operated by small governmental jurisdictions located within an 
    urbanized area and serving a population less than 1,000 people where 
    the permitting authority has determined the MS4 is not contributing 
    substantially to the pollutant loadings of an interconnected MS4 
    and, if the MS4 discharges pollutants that have been identified as a 
    cause of impairment in the receiving water of the MS4 then the 
    permitting authority has determined that storm water controls are 
    not needed based on a TMDL that addresses the pollutants of concern.
        The rule allows the permitting authority to waive from coverage 
    MS4s serving a population under 10,000 where the permitting 
    authority has evaluated all waters that receive a discharge from the 
    MS4 and the permitting authority has determined that storm water 
    controls are not needed based on a TMDL that addresses the 
    pollutants of concern and future discharges do not have the 
    potential to result in exceedances of water quality standards.
    
    B. Regulatory Flexibility for Small Construction Activities
    
    Different Compliance, Reporting, or Timetables That Are Responsive 
    to Resources of Small Entities
    
        The rule gives NPDES permitting authorities discretion not to 
    require the submittal of a notice of intent (NOI) for coverage under 
    a NPDES general permit, thereby reducing administrative and 
    financial burden. All construction sites disturbing greater than 5 
    acres must submit an NOI.
    
    Clarifying, Consolidating, or Simplifying Compliance and Reporting 
    Requirements
    
        The rule avoids duplication by allowing the NPDES permitting 
    authority to incorporate by reference State, Tribal, or local 
    programs under a NPDES general permit. Compliance with these 
    programs is considered compliance with the NPDES general permit.
    
    Performance Rather Than Design Standards for Small Entities
    
        The operator of a covered construction activity selects and 
    implement the BMPs most appropriate for the construction site based 
    on the operator's storm water pollution prevention plan.
    
    Waivers for Small Entities From Coverage
    
        Waivers could be granted based on the use of a rainfall 
    erosivity factor or a comprehensive analysis of water quality 
    impacts.
        (A) Low rainfall waiver: When the rainfall erosivity factor 
    (``R'' from Revised Universal Soil Loss Equation) is less than 5 
    during the period of construction activity, a permit is not 
    required.
        (B) Determination based on Water Quality Analysis: The NPDES 
    permitting authority can waive from coverage construction activities 
    disturbing from 1 acre up to 5 acres of land where storm water 
    controls are not needed based on:
        1. A TMDL approved or established by EPA that addresses the 
    pollutants of concern, or
        2. For non-impaired waters, an equivalent analysis that 
    determines that such allocations are not needed to protect water 
    quality based on consideration of existing in-stream concentrations, 
    expected growth in pollutant contributions from all sources, and a 
    margin of safety.
    
    C. Regulatory Flexibility for Industrial/Commercial Facilities
    
    Waivers for Small Entities From Coverage
    
        The rule provides a ``no-exposure'' waiver provision for Phase I 
    industrial/commercial facilities. Qualifying facilities seeking this 
    provision simply need to complete a self-certification form 
    indicating that no industrial materials or activities are exposed to 
    rain, snow, snow melt and/or runoff.
    
    Appendix 6 of Preamble--Governmental Entities Located Fully or 
    Partially Within an Urbanized Area
    
        (This is a reference list only, not a list of all operators of 
    small MS4s subject to Secs. 122.32-122.36. For example, a listed 
    governmental entity is only regulated if it operates a small MS4 
    within an ``urbanized area'' boundary as determined by the Bureau of 
    the Census. Furthermore, entities such as military bases, large 
    hospitals, prison complexes, universities, sewer districts, and 
    highway departments that operate a small MS4 within an urbanized 
    area are also subject to the permitting regulations but are not 
    individually listed here. See Sec. 122.26(b)(16) for the definition 
    of a small MS4 and Sec. 122.32(a) for the definition of a regulated 
    small MS4.)

    Appendix 7 of Preamble--Governmental Entities (Located Outside of 
    an Urbanized Area) That Must Be Examined By the NPDES Permitting 
    Authority for Potential Designation Under Sec. 123.35(b)(2)
    
        (All listed entities have a population of at least 10,000 and a 
    population density of at least 1,000. A listed entity would only be 
    potentially designated if it operates a small MS4. See 
    Sec. 122.26(b)(16) for the definition of a small MS4.)
        (This list does not include all operators of small MS4s that may 
    be designated by the NPDES permitting authority. Operators of small 
    MS4s in areas with populations below 10,000 and densities below 
    1,000 may also be designated but examination of them is not 
    required. Also, entities such as military bases, large hospitals, 
    prison complexes, universities, sewer districts, and highway 
    departments that operate a small MS4 in an area listed here, or in 
    an area otherwise designated by the NPDES permitting authority, may 
    be designated and become subject to permitting regulations.)

        1. The authority citation for part 122 continues to read as 
    follows:
    
        Authority: The Clean Water Act, 33 U.S.C. 1251 et seq.
    
        2. Revise Sec. 122.21(c)(1) to read as follows:
    
    
    Sec. 122.21  Application for a permit (applicable to State programs, 
    see Sec. 123.25).
    
    * * * * *
        (c) Time to apply. (1) Any person proposing a new discharge, shall 
    submit an application at least 180 days before the date on which the 
    discharge is to commence, unless permission for a later date has been 
    granted by the Director. Facilities proposing a new discharge of storm 
    water associated with industrial activity shall submit an application 
    180 days before that facility commences industrial activity which may 
    result in a discharge of storm water associated with that industrial 
    activity. Facilities described under Sec. 122.26(b)(14)(x) or 
    (b)(15)(i) shall submit applications at least 90 days before the date 
    on which construction is to commence. Different submittal dates may be 
    required under the terms of applicable general permits. Persons 
    proposing a new discharge are encouraged to submit their applications 
    well in advance of the 90 or 180 day requirements to avoid delay. See 
    also paragraph (k) of this section and Sec. 122.26(c)(1)(i)(G) and 
    (c)(1)(ii).

        d. Add paragraphs (e)(8) and (e)(9); and
        e. Revise paragraphs (f)(4), (f)(5), and (g).
        The additions and revisions read as follows:
    
    
    Sec. 122.26  Storm water discharges (applicable to State NPDES 
    programs, see Sec. 123.25).
    
        (a) * * *
        (9)(i) On and after October 1, 1994, for discharges composed 
    entirely of storm water, that are not required by paragraph (a)(1) of 
    this section to obtain a permit, operators shall be required to obtain 
    a NPDES permit only if:
        (A) The discharge is from a small MS4 required to be regulated 
    pursuant to Sec. 122.32;
        (B) The discharge is a storm water discharge associated with small 
    construction activity pursuant to paragraph (b)(15) of this section;
        (C) The Director, or in States with approved NPDES programs either 
    the Director or the EPA Regional Administrator, determines that storm 
    water controls are needed for the discharge based on wasteload 
    allocations that are part of ``total maximum daily loads'' (TMDLs) that 
    address the pollutant(s) of concern; or
        (D) The Director, or in States with approved NPDES programs either 
    the Director or the EPA Regional Administrator, determines that the 
    discharge, or category of discharges within a geographic area, 
    contributes to a violation of a water quality standard or is a 
    significant contributor of pollutants to waters of the United States.
        (ii) Operators of small MS4s designated pursuant to paragraphs 
    (a)(9)(i)(A), (a)(9)(i)(C), and (a)(9)(i)(D) of this section shall seek 
    coverage under an NPDES permit in accordance with Secs. 122.33 through 
    122.35. Operators of non-municipal sources designated pursuant to 
    paragraphs (a)(9)(i)(B), (a)(9)(i)(C), and (a)(9)(i)(D) of this section 
    shall seek coverage under an NPDES permit in accordance with paragraph

        (14) Storm water discharge associated with industrial activity 
    means the discharge from any conveyance that is used for collecting and 
    conveying storm
    
    [[Page 68839]]
    
    water and that is directly related to manufacturing, processing or raw 
    materials storage areas at an industrial plant. The term does not 
    include discharges from facilities or activities excluded from the 
    NPDES program under this part 122. For the categories of industries 
    identified in this section, the term includes, but is not limited to, 
    storm water discharges from industrial plant yards; immediate access 
    roads and rail lines used or traveled by carriers of raw materials, 
    manufactured products, waste material, or by-products used or created 
    by the facility; material handling sites; refuse sites; sites used for 
    the application or disposal of process waste waters (as defined at part 
    401 of this chapter); sites used for the storage and maintenance of 
    material handling equipment; sites used for residual treatment, 
    storage, or disposal; shipping and receiving areas; manufacturing 
    buildings; storage areas (including tank farms) for raw materials, and 
    intermediate and final products; and areas where industrial activity 
    has taken place in the past and significant materials remain and are 
    exposed to storm water. For the purposes of this paragraph, material 
    handling activities include storage, loading and unloading, 
    transportation, or conveyance of any raw material, intermediate 
    product, final product, by-product or waste product. The term excludes 
    areas located on plant lands separate from the plant's industrial 
    activities, such as office buildings and accompanying parking lots as 
    long as the drainage from the excluded areas is not mixed with storm 
    water drained from the above described areas. Industrial facilities 
    (including industrial facilities that are federally, State, or 
    municipally owned or operated that meet the description of the 
    facilities listed in paragraphs (b)(14)(i) through (xi) of this 
    section) include those facilities designated under the provisions of 
    paragraph (a)(1)(v) of this section. The following categories of 
    facilities are considered to be engaging in ``industrial activity'' for 
    purposes of paragraph (b)(14):
    * * * * *
        (x) Construction activity including clearing, grading and 
    excavation, except operations that result in the disturbance of less 
    than five acres of total land area. Construction activity also includes 
    the disturbance of less than five acres of total land area that is a 
    part of a larger common plan of development or sale if the larger 
    common plan will ultimately disturb five acres or more;
        (xi) Facilities under Standard Industrial Classifications 20, 21, 
    22, 23, 2434, 25, 265, 267, 27, 283, 285, 30, 31 (except 311), 323, 34 
    (except 3441), 35, 36, 37 (except 373), 38, 39, and 4221-25;
        (15) Storm water discharge associated with small construction 
    activity means the discharge of storm water from:
        (i) Construction activities including clearing, grading, and 
    excavating that result in land disturbance of equal to or greater than 
    one acre and less than five acres. Small construction activity also 
    includes the disturbance of less than one acre of total land area that 
    is part of a larger common plan of development or sale if the larger 
    common plan will ultimately disturb equal to or greater than one and 
    less than five acres. Small construction activity does not include 
    routine maintenance that is performed to maintain the original line and 
    grade, hydraulic capacity, or original purpose of the facility. The 
    Director may waive the otherwise applicable requirements in a general 
    permit for a storm water discharge from construction activities that 
    disturb less than five acres where:
        (A) The value of the rainfall erosivity factor (``R'' in the 
    Revised Universal Soil Loss Equation) is less than five during the 
    period of construction activity. The rainfall erosivity factor is 
    determined in accordance with Chapter 2 of Agriculture Handbook Number 
    703, Predicting Soil Erosion by Water: A Guide to Conservation Planning 
    With the Revised Universal Soil Loss Equation (RUSLE), pages 21-64, 
    dated January 1997. The Director of the Federal Register approves this 
    incorporation by reference in accordance with 5 U.S.C 552(a) and 1 CFR 
    part 51. Copies may be obtained from EPA's Water Resource Center, Mail 
    Code RC4100, 401 M St. S.W., Washington, DC 20460. A copy is also 
    available for inspection at the U.S. EPA Water Docket , 401 M Street 
    S.W., Washington, DC. 20460, or the Office of the Federal Register, 800 
    N. Capitol Street N.W. Suite 700, Washington, DC. An operator must 
    certify to the Director that the construction activity will take place 
    during a period when the value of the rainfall erosivity factor is less 
    than five; or
        (B) Storm water controls are not needed based on a ``total maximum 
    daily load'' (TMDL) approved or established by EPA that addresses the 
    pollutant(s) of concern or, for non-impaired waters that do not require 
    TMDLs, an equivalent analysis that determines allocations for small 
    construction sites for the pollutant(s) of concern or that determines 
    that such allocations are not needed to protect water quality based on 
    consideration of existing in-stream concentrations, expected growth in 
    pollutant contributions from all sources, and a margin of safety. For 
    the purpose of this paragraph, the pollutant(s) of concern include 
    sediment or a parameter that addresses sediment (such as total 
    suspended solids, turbidity or siltation) and any other pollutant that 
    has been identified as a cause of impairment of any water body that 
    will receive a discharge from the construction activity. The operator 
    must certify to the Director that the construction activity will take 
    place, and storm water discharges will occur, within the drainage area 
    addressed by the TMDL or equivalent analysis.
        (ii) Any other construction activity designated by the Director, or 
    in States with approved NPDES programs either the Director or the EPA 
    Regional Administrator, based on the potential for contribution to a 
    violation of a water quality standard or for significant contribution 
    of pollutants to waters of the United States.

    * * * * *
        (c) Application requirements for storm water discharges associated 
    with industrial activity and storm water discharges associated with 
    small construction activity--(1) Individual application. Dischargers of 
    storm water associated with industrial activity and with small 
    construction activity are required to apply for an individual permit or 
    seek coverage under a promulgated storm water general permit. * * *
    * * * * *
        (ii) An operator of an existing or new storm water discharge that 
    is associated with industrial activity solely under paragraph 
    (b)(14)(x) of this section or is associated with small construction 
    activity solely under paragraph (b)(15) of this section, is exempt from 
    the requirements of Sec. 122.21(g) and paragraph (c)(1)(i) of this

    general or individual permit, other than an airport, powerplant, or 
    uncontrolled sanitary landfill, the permit application must be 
    submitted to the Director by March 10, 2003.
    * * * * *
        (5) A permit application shall be submitted to the Director within 
    180 days of notice, unless permission for a later date is granted by 
    the Director (see Sec. 124.52(c) of this chapter), for:
        (i) A storm water discharge that the Director, or in States with 
    approved NPDES programs, either the Director or the EPA Regional 
    Administrator, determines that the discharge contributes to a violation

    section.
        (5) The Director shall make a final determination on any petition 
    received under this section within 90 days after receiving the petition 
    with the exception of petitions to designate a small MS4 in which case 
    the Director shall make a final determination on the petition within 
    180 days after its receipt.
        (g) Conditional exclusion for ``no exposure'' of industrial 
    activities and materials to storm water. Discharges composed entirely 
    of storm water are not storm water discharges associated with 
    industrial activity if there is ``no exposure'' of industrial materials 
    and activities to rain, snow, snowmelt and/or runoff, and the 
    discharger satisfies the conditions in paragraphs (g)(1) through (g)(4) 
    of this section. ``No exposure'' means that all industrial materials 
    and activities are protected by a storm resistant shelter to prevent 
    exposure to rain, snow, snowmelt, and/or runoff. Industrial materials 
    or activities include, but are not limited to, material handling 
    equipment or activities, industrial machinery, raw materials, 
    intermediate products, by-products, final products, or waste
    
    [[Page 68841]]
    
    products. Material handling activities include the storage, loading and 
    unloading, transportation, or conveyance of any raw material, 
    intermediate product, final product or waste product.
        (1) Qualification. To qualify for this exclusion, the operator of 
    the discharge must:
        (i) Provide a storm resistant shelter to protect industrial 
    materials and activities from exposure to rain, snow, snow melt, and 
    runoff;
        (ii) Complete and sign (according to Sec. 122.22) a certification 
    that there are no discharges of storm water contaminated by exposure to 
    industrial materials and activities from the entire facility, except as 
    provided in paragraph (g)(2) of this section;
        (iii) Submit the signed certification to the NPDES permitting 
    authority once every five years;
        (iv) Allow the Director to inspect the facility to determine 
    compliance with the ``no exposure'' conditions;
        (v) Allow the Director to make any ``no exposure'' inspection 
    reports available to the public upon request; and
        (vi) For facilities that discharge through an MS4, upon request, 
    submit a copy of the certification of ``no exposure'' to the MS4 
    operator, as well as allow inspection and public reporting by the MS4 
    operator.
        (2) Industrial materials and activities not requiring storm 
    resistant shelter. To qualify for this exclusion, storm resistant 
    shelter is not required for:
        (i) Drums, barrels, tanks, and similar containers that are tightly 
    sealed, provided those containers are not deteriorated and do not leak 
    (``Sealed'' means banded or otherwise secured and without operational 
    taps or valves);
        (ii) Adequately maintained vehicles used in material handling; and
        (iii) Final products, other than products that would be mobilized 
    in storm water discharge (e.g., rock salt).
        (3) Limitations. (i) Storm water discharges from construction 
    activities identified in paragraphs (b)(14)(x) and (b)(15) are not 
    eligible for this conditional exclusion.
        (ii) This conditional exclusion from the requirement for an NPDES 
    permit is available on a facility-wide basis only, not for individual 
    outfalls. If a facility has some discharges of storm water that would 
    otherwise be ``no exposure'' discharges, individual permit requirements 
    should be adjusted accordingly.
        (iii) If circumstances change and industrial materials or 
    activities become exposed to rain, snow, snow melt, and/or runoff, the 
    conditions for this exclusion no longer apply. In such cases, the 
    discharge becomes subject to enforcement for un-permitted discharge. 
    Any conditionally exempt discharger who anticipates changes in 
    circumstances should apply for and obtain permit authorization prior to 
    the change of circumstances.
        (iv) Notwithstanding the provisions of this paragraph, the NPDES 
    permitting authority retains the authority to require permit 
    authorization (and deny this exclusion) upon making a determination 
    that the discharge causes, has a reasonable potential to cause, or 
    contributes to an instream excursion above an applicable water quality 
    standard, including designated uses.
        (4) Certification. The no exposure certification must require the 
    submission of the following information, at a minimum, to aid the NPDES 
    permitting authority in determining if the facility qualifies for the 
    no exposure exclusion:
        (i) The legal name, address and phone number of the discharger (see 
    Sec. 122.21(b));
        (ii) The facility name and address, the county name and the 
    latitude and longitude where the facility is located;
        (iii) The certification must indicate that none of the following 
    materials or activities are, or will be in the foreseeable future, 
    exposed to precipitation:
        (A) Using, storing or cleaning industrial machinery or equipment, 
    and areas where residuals from using, storing or cleaning industrial 
    machinery or equipment remain and are exposed to storm water;
        (B) Materials or residuals on the ground or in storm water inlets 
    from spills/leaks;
        (C) Materials or products from past industrial activity;
        (D) Material handling equipment (except adequately maintained 
    vehicles);
        (E) Materials or products during loading/unloading or transporting 
    activities;
        (F) Materials or products stored outdoors (except final products 
    intended for outside use, e.g., new cars, where exposure to storm water 
    does not result in the discharge of pollutants);
        (G) Materials contained in open, deteriorated or leaking storage 
    drums, barrels, tanks, and similar containers;
        (H) Materials or products handled/stored on roads or railways owned 
    or maintained by the discharger;
        (I) Waste material (except waste in covered, non-leaking 
    containers, e.g., dumpsters);
        (J) Application or disposal of process wastewater (unless otherwise 
    permitted); and
        (K) Particulate matter or visible deposits of residuals from roof 
    stacks/vents not otherwise regulated, i.e., under an air quality 
    control permit, and evident in the storm water outflow;
        (iv) All ``no exposure'' certifications must include the following 
    certification statement, and be signed in accordance with the signatory 
    requirements of Sec. 122.22: ``I certify under penalty of law that I 
    have read and understand the eligibility requirements for claiming a 
    condition of ``no exposure'' and obtaining an exclusion from NPDES 
    storm water permitting; and that there are no discharges of storm water 
    contaminated by exposure to industrial activities or materials from the 
    industrial facility identified in this document (except as allowed 
    under paragraph (g)(2)) of this section. I understand that I am 
    obligated to submit a no exposure certification form once every five 
    years to the NPDES permitting authority and, if requested, to the 
    operator of the local MS4 into which this facility discharges (where 
    applicable). I understand that I must allow the NPDES permitting 
    authority, or MS4 operator where the discharge is into the local MS4, 
    to perform inspections to confirm the condition of no exposure and to 
    make such inspection reports publicly available upon request. I 
    understand that I must obtain coverage under an NPDES permit prior to 
    any point source discharge of storm water from the facility. I certify 
    under penalty of law that this document and all attachments were 
    prepared under my direction or supervision in accordance with a system 
    designed to assure that qualified personnel properly gathered and 
    evaluated the information submitted. Based upon my inquiry of the 
    person or persons who manage the system, or those persons directly 
    involved in gathering the information, the information submitted is to 
    the best of my knowledge and belief true, accurate and complete. I am 
    aware there are significant penalties for submitting false information, 
    including the possibility of fine and imprisonment for knowing 
    violations.''
        4. Revise Sec. 122.28(b)(2)(v) to read as follows:

    separate storm sewer systems, primary industrial facilities, and storm 
    water discharges associated with industrial activity, may, at the 
    discretion of the Director, be authorized to discharge under a general 
    permit without submitting a notice of intent where the Director finds 
    that a notice of intent requirement would be inappropriate. In making 
    such a finding, the Director shall consider: the type of discharge; the 
    expected nature of the discharge; the potential for toxic and 
    conventional pollutants in the discharges; the expected volume of the 
    discharges; other means of identifying discharges covered by the 
    permit; and the estimated number of discharges to be covered by the 
    permit. The Director shall provide in the public notice of the general 
    permit the reasons for not requiring a notice of intent.
    * * * * *
        5. Add Secs. 122.30 through 122.37 to subpart B to read as follows:
    
    
    Sec. 122.30  What are the objectives of the storm water regulations for 
    small MS4s?
    
        (a) Sections 122.30 through 122.37 are written in a ``readable 
    regulation'' format that includes both rule requirements and EPA 
    guidance that is not legally binding. EPA has clearly distinguished its 
    recommended guidance from the rule requirements by putting the guidance 
    in a separate paragraph headed by the word ``guidance''.
        (b) Under the statutory mandate in section 402(p)(6) of the Clean 
    Water Act, the purpose of this portion of the storm water program is to 
    designate additional sources that need to be regulated to protect water 
    quality and to establish a comprehensive storm water program to 
    regulate these sources. (Because the storm water program is part of the 
    National Pollutant Discharge Elimination System (NPDES) Program, you 
    should also refer to Sec. 122.1 which addresses the broader purpose of 
    the NPDES program.)
        (c) Storm water runoff continues to harm the nation's waters. 
    Runoff from lands modified by human activities can harm surface water 
    resources in several ways including by changing natural hydrologic 
    patterns and by elevating pollutant concentrations and loadings. Storm 
    water runoff may contain or mobilize high levels of contaminants, such 
    as sediment, suspended solids, nutrients, heavy metals, pathogens, 
    toxins, oxygen-demanding substances, and floatables.
        (d) EPA strongly encourages partnerships and the watershed approach 
    as the management framework for efficiently, effectively, and 
    consistently protecting and restoring aquatic ecosystems and protecting 
    public health.
    
    
    Sec. 122.31  As a Tribe, what is my role under the NPDES storm water 
    program?
    
        As a Tribe you may:
        (a) Be authorized to operate the NPDES program including the storm 
    water program, after EPA determines that you are eligible for treatment 
    in the same manner as a State under Secs. 123.31 through 123.34 of this 
    chapter. (If you do not have an authorized NPDES program, EPA 
    implements the program for discharges on your reservation as well as 
    other Indian country, generally.);
        (b) Be classified as an owner of a regulated small MS4, as defined 
    in Sec. 122.32. (Designation of your Tribe as an owner of a small MS4 
    for purposes of this part is an approach that is consistent with EPA's 
    1984 Indian Policy of operating on a government-to-government basis 
    with EPA looking to Tribes as the lead governmental authorities to 
    address environmental issues on their reservations as appropriate. If 
    you operate a separate storm sewer system that meets the definition of 
    a regulated small MS4, you are subject to the requirements under 
    Secs. 122.33 through 122.35. If you are not designated as a regulated 
    small MS4, you may ask EPA to designate you as such for the purposes of 
    this part.); or
        (c) Be a discharger of storm water associated with industrial 
    activity or small construction activity under Secs. 122.26(b)(14) or 
    (b)(15), in which case you must meet the applicable requirements. 
    Within Indian country, the NPDES permitting authority is generally EPA, 
    unless you are authorized to administer the NPDES program.
    
    
    Sec. 122.32  As an operator of a small MS4, am I regulated under the 
    NPDES storm water program?
    
        (a) Unless you qualify for a waiver under paragraph (c) of this 
    section, you are regulated if you operate a small MS4, including but 
    not limited to systems operated by federal, State, Tribal, and local 
    governments, including State departments of transportation; and:
        (1) Your small MS4 is located in an urbanized area as determined by 
    the latest Decennial Census by the Bureau of the Census. (If your small 
    MS4 is not located entirely within an urbanized area, only the portion 
    that is within the urbanized area is regulated); or
        (2) You are designated by the NPDES permitting authority, including 
    where the designation is pursuant to Secs. 123.35(b)(3) and (b)(4) of 
    this chapter, or is based upon a petition under Sec. 122.26(f).
        (b) You may be the subject of a petition to the NPDES permitting 
    authority to require an NPDES permit for your discharge of storm water. 
    If the NPDES permitting authority determines that you need a permit, 
    you are required to comply with Secs. 122.33 through 122.35.
        (c) The NPDES permitting authority may waive the requirements 
    otherwise applicable to you if you meet the criteria of paragraph (d) 
    or (e) of this section. If you receive a waiver under this section, you 
    may subsequently be required to seek coverage under an NPDES permit in 
    accordance with Sec. 122.33(a) if circumstances change. (See also 
    Sec. 123.35(b) of this chapter.)
        (d) The NPDES permitting authority may waive permit coverage if 
    your MS4 serves a population of less than 1,000 within the urbanized 
    area and you meet the following criteria:
        (1) Your system is not contributing substantially to the pollutant 
    loadings of a physically interconnected MS4 that is regulated by the 
    NPDES storm water program (see Sec. 123.35(b)(4) of this chapter); and
        (2) If you discharge any pollutant(s) that have been identified as 
    a cause of impairment of any water body to which you discharge, storm 
    water controls are not needed based on wasteload allocations that are 
    part of an EPA approved or established ``total maximum daily load'' 
    (TMDL) that addresses the pollutant(s) of concern.
        (e) The NPDES permitting authority may waive permit coverage if 
    your MS4 serves a population under 10,000 and you meet the following 
    criteria:
        (1) The permitting authority has evaluated all waters of the U.S., 
    including small streams, tributaries, lakes, and ponds, that receive a 
    discharge from your MS4;
        (2) For all such waters, the permitting authority has determined 
    that storm water controls are not needed based on wasteload allocations 
    that are part of an EPA approved or established TMDL that addresses the 
    pollutant(s) of concern or, if a TMDL has not been developed or 
    approved, an equivalent analysis that determines sources and 
    allocations for the pollutant(s) of concern;
        (3) For the purpose of this paragraph (e), the pollutant(s) of 
    concern include biochemical oxygen demand (BOD), sediment or a 
    parameter that addresses sediment (such as total suspended solids, 
    turbidity or siltation), pathogens, oil and grease, and any pollutant 
    that has been identified as a cause of impairment of any water body 
    that will receive a discharge from your MS4; and
    
    [[Page 68843]]
    
        (4) The permitting authority has determined that future discharges 
    from your MS4 do not have the potential to result in exceedances of 
    water quality standards, including impairment of designated uses, or 
    other significant water quality impacts, including habitat and 
    biological impacts.
    
    
    Sec. 122.33  If I am an operator of a regulated small MS4, how do I 
    apply for an NPDES permit and when do I have to apply?
    
        (a) If you operate a regulated small MS4 under Sec. 122.32, you 
    must seek coverage under a NPDES permit issued by your NPDES permitting 
    authority. If you are located in an NPDES authorized State, Tribe, or 
    Territory, then that State, Tribe, or Territory is your NPDES 
    permitting authority. Otherwise, your NPDES permitting authority is the 
    EPA Regional Office.
        (b) You must seek authorization to discharge under a general or 
    individual NPDES permit, as follows:
        (1) If your NPDES permitting authority has issued a general permit 
    applicable to your discharge and you are seeking coverage under the 
    general permit, you must submit a Notice of Intent (NOI) that includes 
    the information on your best management practices and measurable goals 
    required by Sec. 122.34(d). You may file your own NOI, or you and other 
    municipalities or governmental entities may jointly submit an NOI. If 
    you want to share responsibilities for meeting the minimum measures 
    with other municipalities or governmental entities, you must submit an 
    NOI that describes which minimum measures you will implement and 
    identify the entities that will implement the other minimum measures 
    within the area served by your MS4. The general permit will explain any 
    other steps necessary to obtain permit authorization.
        (2)(i) If you are seeking authorization to discharge under an 
    individual permit and wish to implement a program under Sec. 122.34, 
    you must submit an application to your NPDES permitting authority that 
    includes the information required under Secs. 122.21(f) and 122.34(d), 
    an estimate of square mileage served by your small MS4, and any 
    additional information that your NPDES permitting authority requests. A 
    storm sewer map that satisfies the requirement of Sec. 122.34(b)(3)(i) 
    will satisfy the map requirement in Sec. 122.21(f)(7).
        (ii) If you are seeking authorization to discharge under an 
    individual permit and wish to implement a program that is different 
    from the program under Sec. 122.34, you will need to comply with the 
    permit application requirements of Sec. 122.26(d). You must submit both 
    Parts of the application requirements in Secs. 122.26(d)(1) and (2) by 
    March 10, 2003. You do not need to submit the information required by 
    Secs. 122.26(d)(1)(ii) and (d)(2) regarding your legal authority, 
    unless you intend for the permit writer to take such information into 
    account when developing your other permit conditions.
        (iii) If allowed by your NPDES permitting authority, you and 
    another regulated entity may jointly apply under either paragraph 
    (b)(2)(i) or (b)(2)(ii) of this section to be co-permittees under an 
    individual permit.
        (3) If your small MS4 is in the same urbanized area as a medium or 
    large MS4 with an NPDES storm water permit and that other MS4 is 
    willing to have you participate in its storm water program, you and the 
    other MS4 may jointly seek a modification of the other MS4 permit to 
    include you as a limited co-permittee. As a limited co-permittee, you 
    will be responsible for compliance with the permit's conditions 
    applicable to your jurisdiction. If you choose this option you will 
    need to comply with the permit application requirements of Sec. 122.26, 
    rather than the requirements of Sec. 122.34. You do not need to comply 
    with the specific application requirements of Sec. 122.26(d)(1)(iii) 
    and (iv) and (d)(2)(iii) (discharge characterization). You may satisfy 
    the requirements in Sec. 122.26 (d)(1)(v) and (d)(2)(iv) 
    (identification of a management program) by referring to the other 
    MS4's storm water management program.
        (4) Guidance: In referencing an MS4's storm water management 
    program, you should briefly describe how the existing plan will address 
    discharges from your small MS4 or would need to be supplemented in 
    order to adequately address your discharges. You should also explain 
    your role in coordinating storm water pollutant control activities in 
    your MS4, and detail the resources available to you to accomplish the 
    plan.
        (c) If you operate a regulated small MS4:
        (1) Designated under Sec. 122.32(a)(1), you must apply for coverage 
    under an NPDES permit, or apply for a modification of an existing NPDES 
    permit under paragraph (b)(3) of this section by March 10, 2003, unless 
    your MS4 serves a jurisdiction with a population under 10,000 and the 
    NPDES permitting authority has established a phasing schedule under 
    Sec. 123.35(d)(3) of this chapter.
        (2) Designated under Sec. 122.32(a)(2), you must apply for coverage 
    under an NPDES permit, or apply for a modification of an existing NPDES 
    permit under paragraph (b)(3) of this section, within 180 days of 
    notice, unless the NPDES permitting authority grants a later date.
    
    
    Sec. 122.34  As an operator of a regulated small MS4, what will my 
    NPDES MS4 storm water permit require?
    
        (a) Your NPDES MS4 permit will require at a minimum that you 
    develop, implement, and enforce a storm water management program 
    designed to reduce the discharge of pollutants from your MS4 to the 
    maximum extent practicable (MEP), to protect water quality, and to 
    satisfy the appropriate water quality requirements of the Clean Water 
    Act. Your storm water management program must include the minimum 
    control measures described in paragraph (b) of this section unless you 
    apply for a permit under Sec. 122.26(d). For purposes of this section, 
    narrative effluent limitations requiring implementation of best 
    management practices (BMPs) are generally the most appropriate form of 
    effluent limitations when designed to satisfy technology requirements 
    (including reductions of pollutants to the maximum extent practicable) 
    and to protect water quality. Implementation of best management 
    practices consistent with the provisions of the storm water management 
    program required pursuant to this section and the provisions of the 
    permit required pursuant to Sec. 122.33 constitutes compliance with the 
    standard of reducing pollutants to the ``maximum extent practicable.'' 
    Your NPDES permitting authority will specify a time period of up to 5 
    years from the date of permit issuance for you to develop and implement 
    your program.
        (b) Minimum control measures--(1) Public education and outreach on 
    storm water impacts. (i) You must implement a public education program 
    to distribute educational materials to the community or conduct 
    equivalent outreach activities about the impacts of storm water 
    discharges on water bodies and the steps that the public can take to 
    reduce pollutants in storm water runoff.
        (ii) Guidance: You may use storm water educational materials 
    provided by your State, Tribe, EPA, environmental, public interest or 
    trade organizations, or other MS4s. The public education program should 
    inform individuals and households about the steps they can take to 
    reduce storm water pollution, such as ensuring proper septic system 
    maintenance, ensuring the proper use and disposal of landscape and 
    garden chemicals including fertilizers and pesticides, protecting and 
    restoring riparian vegetation, and properly disposing of used motor oil 
    or
    
    [[Page 68844]]
    
    household hazardous wastes. EPA recommends that the program inform 
    individuals and groups how to become involved in local stream and beach 
    restoration activities as well as activities that are coordinated by 
    youth service and conservation corps or other citizen groups. EPA 
    recommends that the public education program be tailored, using a mix 
    of locally appropriate strategies, to target specific audiences and 
    communities. Examples of strategies include distributing brochures or 
    fact sheets, sponsoring speaking engagements before community groups, 
    providing public service announcements, implementing educational 
    programs targeted at school age children, and conducting community-
    based projects such as storm drain stenciling, and watershed and beach 
    cleanups. In addition, EPA recommends that some of the materials or 
    outreach programs be directed toward targeted groups of commercial, 
    industrial, and institutional entities likely to have significant storm 
    water impacts. For example, providing information to restaurants on the 
    impact of grease clogging storm drains and to garages on the impact of 
    oil discharges. You are encouraged to tailor your outreach program to 
    address the viewpoints and concerns of all communities, particularly 
    minority and disadvantaged communities, as well as any special concerns 
    relating to children.
        (2) Public involvement/participation. (i) You must, at a minimum, 
    comply with State, Tribal and local public notice requirements when 
    implementing a public involvement/ participation program.
        (ii) Guidance: EPA recommends that the public be included in 
    developing, implementing, and reviewing your storm water management 
    program and that the public participation process should make efforts 
    to reach out and engage all economic and ethnic groups. Opportunities 
    for members of the public to participate in program development and 
    implementation include serving as citizen representatives on a local 
    storm water management panel, attending public hearings, working as 
    citizen volunteers to educate other individuals about the program, 
    assisting in program coordination with other pre-existing programs, or 
    participating in volunteer monitoring efforts. (Citizens should obtain 
    approval where necessary for lawful access to monitoring sites.)
        (3) Illicit discharge detection and elimination. (i) You must 
    develop, implement and enforce a program to detect and eliminate 
    illicit discharges (as defined at Sec. 122.26(b)(2)) into your small 
    MS4.
        (ii) You must:
        (A) Develop, if not already completed, a storm sewer system map, 
    showing the location of all outfalls and the names and location of all 
    waters of the United States that receive discharges from those 
    outfalls;
        (B) To the extent allowable under State, Tribal or local law, 
    effectively prohibit, through ordinance, or other regulatory mechanism, 
    non-storm water discharges into your storm sewer system and implement 
    appropriate enforcement procedures and actions;
        (C) Develop and implement a plan to detect and address non-storm 
    water discharges, including illegal dumping, to your system; and
        (D) Inform public employees, businesses, and the general public of 
    hazards associated with illegal discharges and improper disposal of 
    waste.
        (iii) You need address the following categories of non-storm water 
    discharges or flows (i.e., illicit discharges) only if you identify 
    them as significant contributors of pollutants to your small MS4: water 
    line flushing, landscape irrigation, diverted stream flows, rising 
    ground waters, uncontaminated ground water infiltration (as defined at 
    40 CFR 35.2005(20)), uncontaminated pumped ground water, discharges 
    from potable water sources, foundation drains, air conditioning 
    condensation, irrigation water, springs, water from crawl space pumps, 
    footing drains, lawn watering, individual residential car washing, 
    flows from riparian habitats and wetlands, dechlorinated swimming pool 
    discharges, and street wash water (discharges or flows from fire 
    fighting activities are excluded from the effective prohibition against 
    non-storm water and need only be addressed where they are identified as 
    significant sources of pollutants to waters of the United States).
        (iv) Guidance: EPA recommends that the plan to detect and address 
    illicit discharges include the following four components: procedures 
    for locating priority areas likely to have illicit discharges; 
    procedures for tracing the source of an illicit discharge; procedures 
    for removing the source of the discharge; and procedures for program 
    evaluation and assessment. EPA recommends visually screening outfalls 
    during dry weather and conducting field tests of selected pollutants as 
    part of the procedures for locating priority areas. Illicit discharge 
    education actions may include storm drain stenciling, a program to 
    promote, publicize, and facilitate public reporting of illicit 
    connections or discharges, and distribution of outreach materials.
        (4) Construction site storm water runoff control. (i) You must 
    develop, implement, and enforce a program to reduce pollutants in any 
    storm water runoff to your small MS4 from construction activities that 
    result in a land disturbance of greater than or equal to one acre. 
    Reduction of storm water discharges from construction activity 
    disturbing less than one acre must be included in your program if that 
    construction activity is part of a larger common plan of development or 
    sale that would disturb one acre or more. If the NPDES permitting 
    authority waives requirements for storm water discharges associated 
    with small construction activity in accordance with 
    Sec. 122.26(b)(15)(i), you are not required to develop, implement, and/
    or enforce a program to reduce pollutant discharges from such sites.
        (ii) Your program must include the development and implementation 
    of, at a minimum:
        (A) An ordinance or other regulatory mechanism to require erosion 
    and sediment controls, as well as sanctions to ensure compliance, to 
    the extent allowable under State, Tribal, or local law;
        (B) Requirements for construction site operators to implement 
    appropriate erosion and sediment control best management practices;
        (C) Requirements for construction site operators to control waste 
    such as discarded building materials, concrete truck washout, 
    chemicals, litter, and sanitary waste at the construction site that may 
    cause adverse impacts to water quality;
        (D) Procedures for site plan review which incorporate consideration 
    of potential water quality impacts;
        (E) Procedures for receipt and consideration of information 
    submitted by the public, and
        (F) Procedures for site inspection and enforcement of control 
    measures.
        (iii) Guidance: Examples of sanctions to ensure compliance include 
    non-monetary penalties, fines, bonding requirements and/or permit 
    denials for non-compliance. EPA recommends that procedures for site 
    plan review include the review of individual pre-construction site 
    plans to ensure consistency with local sediment and erosion control 
    requirements. Procedures for site inspections and enforcement of 
    control measures could include steps to identify priority sites for 
    inspection and enforcement based on the nature of the construction 
    activity, topography, and the characteristics of soils and receiving
    
    [[Page 68845]]
    
    water quality. You are encouraged to provide appropriate educational 
    and training measures for construction site operators. You may wish to 
    require a storm water pollution prevention plan for construction sites 
    within your jurisdiction that discharge into your system. See 
    Sec. 122.44(s) (NPDES permitting authorities' option to incorporate 
    qualifying State, Tribal and local erosion and sediment control 
    programs into NPDES permits for storm water discharges from 
    construction sites). Also see Sec. 122.35(b) (The NPDES permitting 
    authority may recognize that another government entity, including the 
    permitting authority, may be responsible for implementing one or more 
    of the minimum measures on your behalf.)
        (5) Post-construction storm water management in new development and 
    redevelopment.
        (i) You must develop, implement, and enforce a program to address 
    storm water runoff from new development and redevelopment projects that 
    disturb greater than or equal to one acre, including projects less than 
    one acre that are part of a larger common plan of development or sale, 
    that discharge into your small MS4. Your program must ensure that 
    controls are in place that would prevent or minimize water quality 
    impacts.
        (ii) You must:
        (A) Develop and implement strategies which include a combination of 
    structural and/or non-structural best management practices (BMPs) 
    appropriate for your community;
        (B) Use an ordinance or other regulatory mechanism to address post-
    construction runoff from new development and redevelopment projects to 
    the extent allowable under State, Tribal or local law; and
        (C) Ensure adequate long-term operation and maintenance of BMPs.
        (iii) Guidance: If water quality impacts are considered from the 
    beginning stages of a project, new development and potentially 
    redevelopment provide more opportunities for water quality protection. 
    EPA recommends that the BMPs chosen: be appropriate for the local 
    community; minimize water quality impacts; and attempt to maintain pre-
    development runoff conditions. In choosing appropriate BMPs, EPA 
    encourages you to participate in locally-based watershed planning 
    efforts which attempt to involve a diverse group of stakeholders 
    including interested citizens. When developing a program that is 
    consistent with this measure's intent, EPA recommends that you adopt a 
    planning process that identifies the municipality's program goals 
    (e.g., minimize water quality impacts resulting from post-construction 
    runoff from new development and redevelopment), implementation 
    strategies (e.g., adopt a combination of structural and/or non-
    structural BMPs), operation and maintenance policies and procedures, 
    and enforcement procedures. In developing your program, you should 
    consider assessing existing ordinances, policies, programs and studies 
    that address storm water runoff quality. In addition to assessing these 
    existing documents and programs, you should provide opportunities to 
    the public to participate in the development of the program. Non-
    structural BMPs are preventative actions that involve management and 
    source controls such as: policies and ordinances that provide 
    requirements and standards to direct growth to identified areas, 
    protect sensitive areas such as wetlands and riparian areas, maintain 
    and/or increase open space (including a dedicated funding source for 
    open space acquisition), provide buffers along sensitive water bodies, 
    minimize impervious surfaces, and minimize disturbance of soils and 
    vegetation; policies or ordinances that encourage infill development in 
    higher density urban areas, and areas with existing infrastructure; 
    education programs for developers and the public about project designs 
    that minimize water quality impacts; and measures such as minimization 
    of percent impervious area after development and minimization of 
    directly connected impervious areas. Structural BMPs include: storage 
    practices such as wet ponds and extended-detention outlet structures; 
    filtration practices such as grassed swales, sand filters and filter 
    strips; and infiltration practices such as infiltration basins and 
    infiltration trenches. EPA recommends that you ensure the appropriate 
    implementation of the structural BMPs by considering some or all of the 
    following: pre-construction review of BMP designs; inspections during 
    construction to verify BMPs are built as designed; post-construction 
    inspection and maintenance of BMPs; and penalty provisions for the 
    noncompliance with design, construction or operation and maintenance. 
    Storm water technologies are constantly being improved, and EPA 
    recommends that your requirements be responsive to these changes, 
    developments or improvements in control technologies.
        (6) Pollution prevention/good housekeeping for municipal 
    operations. (i) You must develop and implement an operation and 
    maintenance program that includes a training component and has the 
    ultimate goal of preventing or reducing pollutant runoff from municipal 
    operations. Using training materials that are available from EPA, your 
    State, Tribe, or other organizations, your program must include 
    employee training to prevent and reduce storm water pollution from 
    activities such as park and open space maintenance, fleet and building 
    maintenance, new construction and land disturbances, and storm water 
    system maintenance.
        (ii) Guidance: EPA recommends that, at a minimum, you consider the 
    following in developing your program: maintenance activities, 
    maintenance schedules, and long-term inspection procedures for 
    structural and non-structural storm water controls to reduce floatables 
    and other pollutants discharged from your separate storm sewers; 
    controls for reducing or eliminating the discharge of pollutants from 
    streets, roads, highways, municipal parking lots, maintenance and 
    storage yards, fleet or maintenance shops with outdoor storage areas, 
    salt/sand storage locations and snow disposal areas operated by you, 
    and waste transfer stations; procedures for properly disposing of waste 
    removed from the separate storm sewers and areas listed above (such as 
    dredge spoil, accumulated sediments, floatables, and other debris); and 
    ways to ensure that new flood management projects assess the impacts on 
    water quality and examine existing projects for incorporating 
    additional water quality protection devices or practices. Operation and 
    maintenance should be an integral component of all storm water 
    management programs. This measure is intended to improve the efficiency 
    of these programs and require new programs where necessary. Properly 
    developed and implemented operation and maintenance programs reduce the 
    risk of water quality problems.
        (c) If an existing qualifying local program requires you to 
    implement one or more of the minimum control measures of paragraph (b) 
    of this section, the NPDES permitting authority may include conditions 
    in your NPDES permit that direct you to follow that qualifying 
    program's requirements rather than the requirements of paragraph (b) of 
    this section. A qualifying local program is a local, State or Tribal 
    municipal storm water management program that imposes, at a minimum, 
    the relevant requirements of paragraph (b) of this section.
        (d)(1) In your permit application (either a notice of intent for 
    coverage
    
    [[Page 68846]]
    
    under a general permit or an individual permit application), you must 
    identify and submit to your NPDES permitting authority the following 
    information:
        (i) The best management practices (BMPs) that you or another entity 
    will implement for each of the storm water minimum control measures at 
    paragraphs (b)(1) through (b)(6) of this section;
        (ii) The measurable goals for each of the BMPs including, as 
    appropriate, the months and years in which you will undertake required 
    actions, including interim milestones and the frequency of the action; 
    and
        (iii) The person or persons responsible for implementing or 
    coordinating your storm water management program.
        (2) If you obtain coverage under a general permit, you are not 
    required to meet any measurable goal(s) identified in your notice of 
    intent in order to demonstrate compliance with the minimum control 
    measures in paragraphs (b)(3) through (b)(6) of this section unless, 
    prior to submitting your NOI, EPA or your State or Tribe has provided 
    or issued a menu of BMPs that addresses each such minimum measure. Even 
    if no regulatory authority issues the menu of BMPs, however, you still 
    must comply with other requirements of the general permit, including 
    good faith implementation of BMPs designed to comply with the minimum 
    measures.
        (3) Guidance: Either EPA or your State or Tribal permitting 
    authority will provide a menu of BMPs. You may choose BMPs from the 
    menu or select others that satisfy the minimum control measures.
        (e)(1) You must comply with any more stringent effluent limitations 
    in your permit, including permit requirements that modify, or are in 
    addition to, the minimum control measures based on an approved total 
    maximum daily load (TMDL) or equivalent analysis. The permitting 
    authority may include such more stringent limitations based on a TMDL 
    or equivalent analysis that determines such limitations are needed to 
    protect water quality.
        (2) Guidance: EPA strongly recommends that until the evaluation of 
    the storm water program in Sec. 122.37, no additional requirements 
    beyond the minimum control measures be imposed on regulated small MS4s 
    without the agreement of the operator of the affected small MS4, except 
    where an approved TMDL or equivalent analysis provides adequate 
    information to develop more specific measures to protect water quality.
        (f) You must comply with other applicable NPDES permit 
    requirements, standards and conditions established in the individual or 
    general permit, developed consistent with the provisions of 
    Secs. 122.41 through 122.49, as appropriate.
        (g) Evaluation and assessment--(1) Evaluation. You must evaluate 
    program compliance, the appropriateness of your identified best 
    management practices, and progress towards achieving your identified 
    measurable goals.
    
        Note to Paragraph (g)(1): The NPDES permitting authority may 
    determine monitoring requirements for you in accordance with State/
    Tribal monitoring plans appropriate to your watershed. Participation 
    in a group monitoring program is encouraged.
    
        (2) Recordkeeping. You must keep records required by the NPDES 
    permit for at least 3 years. You must submit your records to the NPDES 
    permitting authority only when specifically asked to do so. You must 
    make your records, including a description of your storm water 
    management program, available to the public at reasonable times during 
    regular business hours (see Sec. 122.7 for confidentiality provision). 
    (You may assess a reasonable charge for copying. You may require a 
    member of the public to provide advance notice.)
        (3) Reporting. Unless you are relying on another entity to satisfy 
    your NPDES permit obligations under Sec. 122.35(a), you must submit 
    annual reports to the NPDES permitting authority for your first permit 
    term. For subsequent permit terms, you must submit reports in year two 
    and four unless the NPDES permitting authority requires more frequent 
    reports. Your report must include:
        (i) The status of compliance with permit conditions, an assessment 
    of the appropriateness of your identified best management practices and 
    progress towards achieving your identified measurable goals for each of 
    the minimum control measures;
        (ii) Results of information collected and analyzed, including 
    monitoring data, if any, during the reporting period;
        (iii) A summary of the storm water activities you plan to undertake 
    during the next reporting cycle;
        (iv) A change in any identified best management practices or 
    measurable goals for any of the minimum control measures; and
        (v) Notice that you are relying on another governmental entity to 
    satisfy some of your permit obligations (if applicable).
    
    
    Sec. 122.35  As an operator of a regulated small MS4, may I share the 
    responsibility to implement the minimum control measures with other 
    entities?
    
        (a) You may rely on another entity to satisfy your NPDES permit 
    obligations to implement a minimum control measure if:
        (1) The other entity, in fact, implements the control measure;
        (2) The particular control measure, or component thereof, is at 
    least as stringent as the corresponding NPDES permit requirement; and
        (3) The other entity agrees to implement the control measure on 
    your behalf. In the reports you must submit under Sec. 122.34(g)(3), 
    you must also specify that you rely on another entity to satisfy some 
    of your permit obligations. If you are relying on another governmental 
    entity regulated under section 122 to satisfy all of your permit 
    obligations, including your obligation to file periodic reports 
    required by Sec. 122.34(g)(3), you must note that fact in your NOI, but 
    you are not required to file the periodic reports. You remain 
    responsible for compliance with your permit obligations if the other 
    entity fails to implement the control measure (or component thereof). 
    Therefore, EPA encourages you to enter into a legally binding agreement 
    with that entity if you want to minimize any uncertainty about 
    compliance with your permit.
        (b) In some cases, the NPDES permitting authority may recognize, 
    either in your individual NPDES permit or in an NPDES general permit, 
    that another governmental entity is responsible under an NPDES permit 
    for implementing one or more of the minimum control measures for your 
    small MS4 or that the permitting authority itself is responsible. Where 
    the permitting authority does so, you are not required to include such 
    minimum control measure(s) in your storm water management program. (For 
    example, if a State or Tribe is subject to an NPDES permit that 
    requires it to administer a program to control construction site runoff 
    at the State or Tribal level and that program satisfies all of the 
    requirements of Sec. 122.34(b)(4), you could avoid responsibility for 
    the construction measure, but would be responsible for the remaining 
    minimum control measures.) Your permit may be reopened and modified to 
    include the requirement to implement a minimum control measure if the 
    entity fails to implement it.
    
    [[Page 68847]]
    
    Sec. 122.36  As an operator of a regulated small MS4, what happens if I 
    don't comply with the application or permit requirements in 
    Secs. 122.33 through 122.35?
    
        NPDES permits are federally enforceable. Violators may be subject 
    to the enforcement actions and penalties described in Clean Water Act 
    sections 309 (b), (c), and (g) and 505, or under applicable State, 
    Tribal, or local law. Compliance with a permit issued pursuant to 
    section 402 of the Clean Water Act is deemed compliance, for purposes 
    of sections 309 and 505, with sections 301, 302, 306, 307, and 403, 
    except any standard imposed under section 307 for toxic pollutants 
    injurious to human health. If you are covered as a co-permittee under 
    an individual permit or under a general permit by means of a joint 
    Notice of Intent you remain subject to the enforcement actions and 
    penalties for the failure to comply with the terms of the permit in 
    your jurisdiction except as set forth in Sec. 122.35(b).
    
    
    Sec. 122.37  Will the small MS4 storm water program regulations at 
    Secs. 122.32 through 122.36 and Sec. 123.35 of this chapter change in 
    the future?
    
        EPA will evaluate the small MS4 regulations at Secs. 122.32 through 
    122.36 and Sec. 123.35 of this chapter after December 10, 2012 and make 
    any necessary revisions. (EPA intends to conduct an enhanced research 
    effort and compile a comprehensive evaluation of the NPDES MS4 storm 
    water program. EPA will re-evaluate the regulations based on data from 
    the NPDES MS4 storm water program, from research on receiving water 
    impacts from storm water, and the effectiveness of best management 
    practices (BMPs), as well as other relevant information sources.)
        6. In Sec. 122.44, redesignate paragraphs (k)(2) and (k)(3) as 
    paragraphs (k)(3) and (k)(4), remove the comma at the end of newly 
    redesignated paragraph (k)(3) and add a semicolon in its place, and add 
    new paragraphs (k)(2) and (s) to read as follows:
    
    
    Sec. 122.44  Establishing limitations, standards, and other permit 
    conditions (applicable to State NPDES programs, see Sec. 123.25).

    water discharges;
    * * * * *
        (s) Qualifying State, Tribal, or local programs. (1) For storm 
    water discharges associated with small construction activity identified 
    in Sec. 122.26(b)(15), the Director may include permit conditions that 
    incorporate qualifying State, Tribal, or local erosion and sediment 
    control program requirements by reference. Where a qualifying State, 
    Tribal, or local program does not include one or more of the elements 
    in this paragraph (s)(1), then the Director must include those elements 
    as conditions in the permit. A qualifying State, Tribal, or local 
    erosion and sediment control program is one that includes:
        (i) Requirements for construction site operators to implement 
    appropriate erosion and sediment control best management practices;
        (ii) Requirements for construction site operators to control waste 
    such as discarded building materials, concrete truck washout, 
    chemicals, litter, and sanitary waste at the construction site that may 
    cause adverse impacts to water quality;
        (iii) Requirements for construction site operators to develop and 
    implement a storm water pollution prevention plan. (A storm water 
    pollution prevention plan includes site descriptions, descriptions of 
    appropriate control measures, copies of approved State, Tribal or local 
    requirements, maintenance procedures, inspection procedures, and 
    identification of non-storm water discharges); and
        (iv) Requirements to submit a site plan for review that 
    incorporates consideration of potential water quality impacts.
        (2) For storm water discharges from construction activity 
    identified in Sec. 122.26(b)(14)(x), the Director may include permit 
    conditions that incorporate qualifying State, Tribal, or local erosion 
    and sediment control program requirements by reference. A qualifying 
    State, Tribal or local erosion and sediment control program is one that 
    includes the elements listed in paragraph (s)(1) of this section and 
    any additional requirements necessary to achieve the applicable 
    technology-based standards of ``best available technology'' and ``best 
    conventional technology'' based on the best professional judgment of 
    the permit writer.
        7. Add Sec. 122.62(a)(14) to read as follows:
    
    
    Sec. 122.62  Modification or revocation and reissuance of permits 
    (applicable to State programs, see Sec. 123.25).
    
    * * * * *
        (a) * * *
        (14) For a small MS4, to include an effluent limitation requiring 
    implementation of a minimum control measure or measures as specified in 
    Sec. 122.34(b) when:
        (i) The permit does not include such measure(s) based upon the 
    determination that another entity was responsible for implementation of 
    the requirement(s); and
        (ii) The other entity fails to implement measure(s) that satisfy 
    the requirement(s).

    PART 123--STATE PROGRAM REQUIREMENTS
    
        1. The authority citation for part 123 continues to read as 
    follows:
    
        Authority: The Clean Water Act, 33 U.S.C. 1251 et seq.
    
        2. Amend Sec. 123.25 by removing the word ``and'' at the end of 
    paragraph (a)(37), by removing the period at the end of paragraph 
    (a)(38) and adding a semicolon in its place, and by adding paragraphs 
    (a)(39) through (a)(45) to read as follows:
    
    
    Sec. 123.25  Requirements for permitting.
    
        (a) * * *
    
    [[Page 68850]]
    
        (39) Sec. 122.30 (What are the objectives of the storm water 
    regulations for small MS4s?);
        (40) Sec. 122.31 (For Indian Tribes only) (As a Tribe, what is my 
    role under the NPDES storm water program?);
        (41) Sec. 122.32 (As an operator of a small MS4, am I regulated 
    under the NPDES storm water program?);
        (42) Sec. 122.33 (If I am an operator of a regulated small MS4, how 
    do I apply for an NPDES permit? When do I have to apply?);
        (43) Sec. 122.34 (As an operator of a regulated small MS4, what 
    will my NPDES MS4 storm water permit require?);
        (44) Sec. 122.35 (As an operator of a regulated small MS4, may I 
    share the responsibility to implement the minimum control measures with 
    other entities?); and
        (45) Sec. 122.36 (As an operator of a regulated small MS4, what 
    happens if I don't comply with the application or permit requirements 
    in Secs. 122.33 through 122.35?).
    * * * * *
        3. Add Sec. 123.35 to subpart B to read as follows:
    
    
    Sec. 123.35  As the NPDES Permitting Authority for regulated small 
    MS4s, what is my role?
    
        (a) You must comply with the requirements for all NPDES permitting 
    authorities under Parts 122, 123, 124, and 125 of this chapter. (This 
    section is meant only to supplement those requirements and discuss 
    specific issues related to the small MS4 storm water program.)
        (b) You must develop a process, as well as criteria, to designate 
    small MS4s other than those described in Sec. 122.32(a)(1) of this 
    chapter, as regulated small MS4s to be covered under the NPDES storm 
    water discharge control program. This process must include the 
    authority to designate a small MS4 waived under paragraph (d) of this 
    section if circumstances change. EPA may make designations under this 
    section if a State or Tribe fails to comply with the requirements 
    listed in this paragraph. In making designations of small MS4s, you 
    must:
        (1)(i) Develop criteria to evaluate whether a storm water discharge 
    results in or has the potential to result in exceedances of water 
    quality standards, including impairment of designated uses, or other 
    significant water quality impacts, including habitat and biological 
    impacts.
        (ii) Guidance: For determining other significant water quality 
    impacts, EPA recommends a balanced consideration of the following 
    designation criteria on a watershed or other local basis: discharge to 
    sensitive waters, high growth or growth potential, high population 
    density, contiguity to an urbanized area, significant contributor of 
    pollutants to waters of the United States, and ineffective protection 
    of water quality by other programs;
        (2) Apply such criteria, at a minimum, to any small MS4 located 
    outside of an urbanized area serving a jurisdiction with a population 
    density of at least 1,000 people per square mile and a population of at 
    least 10,000;
        (3) Designate any small MS4 that meets your criteria by December 9, 
    2002. You may wait until December 8, 2004 to apply the designation 
    criteria on a watershed basis if you have developed a comprehensive 
    watershed plan. You may apply these criteria to make additional 
    designations at any time, as appropriate; and
        (4) Designate any small MS4 that contributes substantially to the 
    pollutant loadings of a physically interconnected municipal separate 
    storm sewer that is regulated by the NPDES storm water program.
        (c) You must make a final determination within 180 days from 
    receipt of a petition under Sec. 122.26(f) of this chapter (or 
    analogous State or Tribal law). If you do not do so within that time 
    period, EPA may make a determination on the petition.
        (d) You must issue permits consistent with Secs. 122.32 through 
    122.35 of this chapter to all regulated small MS4s. You may waive or 
    phase in the requirements otherwise applicable to regulated small MS4s, 
    as defined in Sec. 122.32(a)(1) of this chapter, under the following 
    circumstances:
        (1) You may waive permit coverage for each small MS4s in 
    jurisdictions with a population under 1,000 within the urbanized area 
    where all of the following criteria have been met:
        (i) Its discharges are not contributing substantially to the 
    pollutant loadings of a physically interconnected regulated MS4 (see 
    paragraph (b)(4) of this section); and
        (ii) If the small MS4 discharges any pollutant(s) that have been 
    identified as a cause of impairment of any water body to which it 
    discharges, storm water controls are not needed based on wasteload 
    allocations that are part of an EPA approved or established ``total 
    maximum daily load'' (TMDL) that address the pollutant(s) of concern.
        (2) You may waive permit coverage for each small MS4 in 
    jurisdictions with a population under 10,000 where all of the following 
    criteria have been met:
        (i) You have evaluated all waters of the U.S., including small 
    streams, tributaries, lakes, and ponds, that receive a discharge from 
    the MS4 eligible for such a waiver.
        (ii) For all such waters, you have determined that storm water 
    controls are not needed based on wasteload allocations that are part of 
    an EPA approved or established TMDL that addresses the pollutant(s) of 
    concern or, if a TMDL has not been developed or approved, an equivalent 
    analysis that determines sources and allocations for the pollutant(s) 
    of concern.
        (iii) For the purpose of paragraph (d)(2)(ii) of this section, the 
    pollutant(s) of concern include biochemical oxygen demand (BOD), 
    sediment or a parameter that addresses sediment (such as total 
    suspended solids, turbidity or siltation), pathogens, oil and grease, 
    and any pollutant that has been identified as a cause of impairment of 
    any water body that will receive a discharge from the MS4.
        (iv) You have determined that current and future discharges from 
    the MS4 do not have the potential to result in exceedances of water 
    quality standards, including impairment of designated uses, or other 
    significant water quality impacts, including habitat and biological 
    impacts.
        (v) Guidance: To help determine other significant water quality 
    impacts, EPA recommends a balanced consideration of the following 
    criteria on a watershed or other local basis: discharge to sensitive 
    waters, high growth or growth potential, high population or commercial 
    density, significant contributor of pollutants to waters of the United 
    States, and ineffective protection of water quality by other programs.
        (3) You may phase in permit coverage for small MS4s serving 
    jurisdictions with a population under 10,000 on a schedule consistent 
    with a State watershed permitting approach. Under this approach, you 
    must develop and implement a schedule to phase in permit coverage for 
    approximately 20 percent annually of all small MS4s that qualify for 
    such phased-in coverage. Under this option, all regulated small MS4s 
    are required to have coverage under an NPDES permit by no later than 
    March 8, 2007. Your schedule for phasing in permit coverage for small 
    MS4s must be approved by the Regional Administrator no later than 
    December 10, 2001.
        (4) If you choose to phase in permit coverage for small MS4s in 
    jurisdictions with a population under 10,000, in accordance with 
    paragraph (d)(3) of this section, you may also provide waivers in 
    accordance with paragraphs (d)(1) and (d)(2) of this section pursuant 
    to your approved schedule.
    
    [[Page 68851]]
    
        (5) If you do not have an approved schedule for phasing in permit 
    coverage, you must make a determination whether to issue an NPDES 
    permit or allow a waiver in accordance with paragraph (d)(1) or (d)(2) 
    of this section, for each eligible MS4 by December 9, 2002.
        (6) You must periodically review any waivers granted in accordance 
    with paragraph (d)(2) of this section to determine whether any of the 
    information required for granting the waiver has changed. At a minimum, 
    you must conduct such a review once every five years. In addition, you 
    must consider any petition to review any waiver when the petitioner 
    provides evidence that the information required for granting the waiver 
    has substantially changed.
        (e) You must specify a time period of up to 5 years from the date 
    of permit issuance for operators of regulated small MS4s to fully 
    develop and implement their storm water program.
        (f) You must include the requirements in Secs. 122.33 through 
    122.35 of this chapter in any permit issued for regulated small MS4s or 
    develop permit limits based on a permit application submitted by a 
    regulated small MS4. (You may include conditions in a regulated small 
    MS4 NPDES permit that direct the MS4 to follow an existing qualifying 
    local program's requirements, as a way of complying with some or all of 
    the requirements in Sec. 122.34(b) of this chapter. See Sec. 122.34(c) 
    of this chapter. Qualifying local, State or Tribal program requirements 
    must impose, at a minimum, the relevant requirements of Sec. 122.34(b) 
    of this chapter.)
        (g) If you issue a general permit to authorize storm water 
    discharges from small MS4s, you must make available a menu of BMPs to 
    assist regulated small MS4s in the design and implementation of 
    municipal storm water management programs to implement the minimum 
    measures specified in Sec. 122.34(b) of this chapter. EPA plans to 
    develop a menu of BMPs that will apply in each State or Tribe that has 
    not developed its own menu. Regardless of whether a menu of BMPs has 
    been developed by EPA, EPA encourages State and Tribal permitting 
    authorities to develop a menu of BMPs that is appropriate for local 
    conditions. EPA also intends to provide guidance on developing BMPs and 
    measurable goals and modify, update, and supplement such guidance based 
    on the assessments of the NPDES MS4 storm water program and research to 
    be conducted over the next thirteen years.
        (h)(1) You must incorporate any additional measures necessary to 
    ensure effective implementation of your State or Tribal storm water 
    program for regulated small MS4s.
        (2) Guidance: EPA recommends consideration of the following:
        (i) You are encouraged to use a general permit for regulated small 
    MS4s;
        (ii) To the extent that your State or Tribe administers a dedicated 
    funding source, you should play an active role in providing financial 
    assistance to operators of regulated small MS4s;
        (iii) You should support local programs by providing technical and 
    programmatic assistance, conducting research projects, performing 
    watershed monitoring, and providing adequate legal authority at the 
    local level;
        (iv) You are encouraged to coordinate and utilize the data 
    collected under several programs including water quality management 
    programs, TMDL programs, and water quality monitoring programs;
        (v) Where appropriate, you may recognize existing responsibilities 
    among governmental entities for the control measures in an NPDES small 
    MS4 permit (see Sec. 122.35(b) of this chapter); and
        (vi) You are encouraged to provide a brief (e.g., two page) 
    reporting format to facilitate compiling and analyzing data from 
    submitted reports under Sec. 122.34(g)(3) of this chapter. EPA intends 
    to develop a model form for this purpose.
    
    PART 124--PROCEDURES FOR DECISIONMAKING
    
        1. The authority citation for part 124 continues to read as 
    follows:
    
        Authority: Resource Conservation and Recovery Act, 42 U.S.C. 
    6901 et seq.; Safe Drinking Water Act, 42 U.S.C. 300(f) et seq.; 
    Clean Water Act, 33 U.S.C. 1251 et seq.; Clean Air Act, 42 U.S.C. 
    7401 et seq.
    
        2. Revise Sec. 124.52(c) to read as follows:
    
    
    Sec. 124.52  Permits required on a case-by-case basis.
    
    * * * * *
        (c) Prior to a case-by-case determination that an individual permit 
    is required for a storm water discharge under this section (see 
    Sec. 122.26(a)(1)(v), (c)(1)(v), and (a)(9)(iii) of this chapter), the 
    Regional Administrator may require the discharger to submit a permit 
    application or other information regarding the discharge under section 
    308 of the CWA. In requiring such information, the Regional 
    Administrator shall notify the discharger in writing and shall send an 
    application form with the notice. The discharger must apply for a 
    permit within 180 days of notice, unless permission for a later date is 
    granted by the Regional Administrator. The question whether the initial 
    designation was proper will remain open for consideration during the 
    public comment period under Sec. 124.11 or Sec. 124.118 and in any 
    subsequent hearing.
