    Reissuance of the National Pollutant Discharge Elimination System 
    (NPDES) General Permit For Dewatering and Petroleum Fuel Contaminated 
    Ground/Storm Waters in the State of Florida
    
    AGENCY: Environmental Protection Agency.
    
    ACTION: Notice of Final Rule--Reissuance of a NPDES General Permit to 
    the State of Florida.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Regional Administrator, EPA, Region IV is reissuing the 
    final National Pollutant Discharge Elimination System (NPDES) General 
    Permit No. FLG830000 to facilities within the political boundary of the 
    State of Florida. This final reissued NPDES general permit contains 
    effluent limitations, prohibitions, reporting requirements and other 
    conditions on facilities which discharge uncontaminated groundwater 
    associated with dewatering or treated groundwater and/or storm water 
    incidental to the groundwater cleanup operation which have been 
    contaminated by automotive gasoline, aviation and/or diesel fuels. This 
    permit authorizes discharges from facilities currently located in and 
    discharging to surface waters within the political boundary of the 
    State of Florida, and any new treatment facilities placed in operation 
    during the term of this permit. Reissuance of this final NPDES will 
    allow general dewatering and cleanup actions at petroleum contaminated 
    sites to begin without the delays of individual NPDES permit issuance 
    procedures.
        For facilities seeking coverage for general dewatering discharges, 
    coverage under the general permit is automatic, upon the permittee's 
    receipt of acceptable groundwater screening values, as described in 
    Part I.A.3(c) of the general permit. The effluent from these general 
    dewatering activities shall be monitored within thirty (30) days after 
    commencement of the discharge and once every six months for the life of 
    the project to maintain coverage under the general permit. 
    Additionally, short-term pump tests, eight (8) hours in duration or 
    less, shall be automatically covered upon receipt of the permittee's 
    Notice of Intent (NOI) by EPA and the permittee will be responsible for 
    meeting the requirements of Parts I.A.1 or A.2. DMRs shall be submitted 
    within thirty (30) days after completion of the pump test discharge.
        Except for facilities meeting the above conditions, all other 
    facilities seeking coverage under the general permit by NOI requests 
    will be responded to by written notification of coverage by certified 
    mail from the Director, Water Management Division, U.S. EPA Region IV. 
    This method of notification will be applicable to both new dischargers 
    applying for coverage for the first time and existing dischargers which 
    are seeking coverage under the reissued general permit. Facilities 
    which are currently discharging under the previous NPDES general permit 
    are required to submit another NOI requesting coverage under the 
    reissued general permit by February 14, 1995, in accordance with Part 
    II, Section F(b).
    
    DATES: This general permit is effective on December 7, 1994, at 1:00 
    p.m. Eastern Daylight Savings Time.
        Dates for coverage: (1) Dewatering Activity discharges are 
    authorized upon the permittee's receipt of acceptable groundwater 
    screening values listed in Part I.A.3. (2) Short-Term Pump Test 
    discharges, eight (8) hours in duration or less, are authorized upon 
    receipt of a complete NOI, as described in Part II, Section F(f). (3) 
    Petroleum Contaminated discharges, are only authorized after written 
    notification of coverage by certified mail from the Director, Water 
    Management Division, U.S. EPA Region IV is received.
        This action constitutes the Environmental Protection Agency's final 
    permit decision, in accordance with Title 40, Code of Federal 
    Regulations (CFR) 124.72.
        The administrative record, including draft NPDES general permit, 
    fact sheet, state certification, comments received, and additional 
    information are available by writing the EPA, Region IV, or for review

    SUPPLEMENTARY INFORMATION:
    
    I. Introduction
    
        On Thursday, August 25, 1988 (53 FR 32442), EPA, Region IV proposed 
    the issuance of the draft NPDES General Permit. During the 30-day 
    comment period, a request for an extension of the comment period was 
    received, and on Tuesday, October 25, 1988 (53 FR 43035), the comment 
    period was extended to November 15, 1988. On Monday, July 17, 1989 (54 
    FR 29986), EPA, Region IV issued the Final NPDES General Permit for 
    Petroleum Fuel Contaminated Ground/Storm Waters in the State of 
    Florida.
        On Friday, February 22, 1991 (56 FR 7379), EPA, Region IV published 
    a notice of a proposed modification to the NPDES General Permit for 
    Petroleum Fuel Contaminated Ground/Storm Waters in the State of Florida 
    (56 FR 7379) to include dewatering activities. On Thursday, August 29, 
    1991 (56 FR 42736), the final modification was issued. The general 
    permit expired on July 16, 1994. On Monday, September 19, 1994, EPA 
    Region IV published a notice concerning the reissuance of the general 
    permit (59 FR 47862) that is being issued in final form today.
        The Region received comments from eight (8) commentors. All the 
    public comments received during the 30-day comment period are included 
    in the administrative record and were considered by Region IV in the 
    formulation of a final determination of the conditions of today's final 
    permit.
        For reference, Region IV published a detailed fact sheet with the 
    proposed draft permit in 59 FR 47862. The Region is incorporating by 
    reference that fact sheet as part of the final fact sheet for today's 
    final permit. The discussions presented in the previous fact sheet 
    should be consulted in reviewing the applicability and scope of the 
    final permit conditions.
        A formal hearing is available to challenge any NPDES permit issued 
    under 40 CFR 124.14 except for a general permit. Persons affected by a 
    general permit may not challenge the conditions of a general permit as 
    a right in further agency proceedings. They may instead either 
    challenge the general permit in court, or apply for an individual 
    permit under 40 CFR 122.21 as authorized at 40 CFR 122.28 and then 
    request a formal hearing on the issuance or denial of an individual 
    permit. Additional information regarding these procedures is available 
    by contacting Ms. Gwen Eason, Office of Regional Counsel, at the 
    address above or at (404) 347-2309.
    
    II. Other Legal Requirements
    
    A. Executive Order 12291
    
        The Office of Management and Budget has exempted this action from 
    the review requirements of Executive Order 12291 pursuant to Section 
    8[b] of that order.
    
    B. Paperwork Reduction Act
    
        EPA has reviewed the requirements imposed on regulated facilities 
    in this final general permit under the Paperwork Reduction Act of 1980, 
    44 U.S.C. Sec. 3501 et seq. The information collection requirements of 
    this permit have already been approved by the Office of Management and 
    Budget in submissions made for the NPDES permit program under the 
    provisions of the Clean Water Act.
    
    C. State Certification Requirements
    
        Section 301(b)(1)(c) of the Act requires that NPDES permits contain 
    conditions which ensure compliance with applicable State water quality 
    standards or limitations. Section 401 of the Act requires that States 
    certify that Federally issued permits are in compliance with State law. 
    This permit is for operations discharging to waters within the State of 
    Florida. Pursuant to 40 CFR 124.53, EPA requested certification of the 
    permit on September 15, 1994. On October 27, 1994, the Florida 
    Department of Environmental Protection waived certification of the 
    general permit.
    
    D. Effective Date
    
        The final NPDES general permit issued today, December 6th, 1994, is 
    effective on December 7, 1994.
    
    E. Regulatory Flexibility Act
    
        After review of the facts presented in this document, I hereby 
    certify, pursuant to the provisions of 5 U.S.C. Sec. 605(b), that this 
    NPDES general permit will not have a significant impact on a 
    substantial number of small entities. Moreover, the permit reduces a 
    significant administrative burden on regulated sources.

    Deputy Regional Administrator.
    
    Summary of Comments
    
    Appendix A--Public Comments
    
        Public notice of the draft permit reissuance was published at 59 FR 
    47862 (September 19, 1994). Additionally, the permit was publicly 
    noticed in five (5) major cities in the State of Florida on September 
    16, 1994, (Public Notice Number 94FL0167), to allow comments from 
    interested parties which would be considered in the formulation of a 
    final decision regarding reissuance of the proposed draft NPDES General 
    Permit No. FLG830000.
        The following parties responded with written comments on reissuance 
    of the proposed NPDES general permit: Florida Department of 
    Environmental Protection (FDEP), Chevron Research & Technology Company, 
    Morgan Lewis & Bockius, Mobil Oil Corporation, Exxon Company, Walt 
    Disney World Company, Florida Chemical Industry Council and the United 
    States Fish and Wildlife Service.
        Comment 1: The Florida Department of Environmental Protection 
    (FDEP), Bureau of Waste Cleanup, submitted comments by letter dated 
    October 3, 1994, which commented on Part I.A.3 of the general permit. 
    The FDEP wanted clarification concerning the intent of Part I.A.3. FDEP 
    stated that the statement on Page two (2) of the introduction states 
    that `` Except for facilities meeting the conditions of Part I.3, 
    written notice of intent to be covered by the reissued NPDES general 
    permit shall be provided to the Permit Issuing Authority prior to 
    initiation of discharge to waters of the United States,'' implies that 
    this includes subparts of Part I.3., including I.3.(a), (b), and (c). 
    FDEP stated that this implies that for discharges that are either 
    uncontaminated or are contaminated with petroleum only and are treated, 
    notification to EPA is not required. It was stated that this is not 
    consistent with the phrase under I.3(a) which states ``upon receipt of 
    written EPA notification of coverage that the Notice of Intent (NOI) 
    request is complete, these short-term discharges may commence.'' The 
    State mentioned that this implies that not only must prior notification 
    be given by EPA for the short-term discharges from sites contaminated 
    by petroleum only, but that the person responsible for the discharge 
    must wait for a reply from EPA, and this inconsistency should be 
    reconciled.
        Response: EPA agrees that the referenced statement on page 2 of the 
    introduction is incorrect. It has been corrected to read, ``except for 
    facilities meeting the conditions of Part I.A.3(c), written NOI to be 
    covered by the reissued permit shall be provided to the Permit Issuing 
    Authority.''
        Comment 2: FDEP stated that it is not reasonable to wait for a 
    response from EPA in order to initiate a short-term discharge for the 
    following reasons: (1) Chapter 62-770, requires that a Remedial Action 
    Plan (RAP) be submitted to the FDEP within 2 months of approval of a 
    Contamination Assessment Report (CAR), and that it is routine to 
    require pump tests to design information for the RAP, plus identify 
    aquifer characteristics. FDEP stated that it is not reasonable to delay 
    the RAP by requiring prior approval from EPA of these simple 8 hour 
    pump tests. (2) Due to varying hydrogeological conditions in Florida, 
    local departments commonly perform dewatering activities in their 
    right-of-way of previous retail service stations, plus have no 
    information before commencing these activities on the existence of 
    petroleum contamination. FDEP stated that these construction projects 
    should not be delayed for an extended period to wait on response from 
    EPA, since mobile treatment units can be deployed and designed to meet 
    EPA's discharge limitations in the NPDES general permit. (3) During 
    dewatering for construction and replacement of underground storage 
    tanks, FDEP mentioned that it was not reasonable for the tank 
    installation to be delayed for an extended period of time; especially 
    since discharges from these operations only last for a few hours at a 
    time and mobile equipment used is very reliable in achieving EPA's 
    discharge standards.
        Response: EPA concurs with FDEP reason No. 1 above which allows 
    short-term 8 hour pump tests at sites which have identified petroleum 
    contamination, to be covered upon receipt of the NOI by the Permit 
    Issuing Authority. Only short-term pump tests, 8 hours in duration or 
    less, designed to obtain information on aquifer characteristics, will 
    be automatically covered upon receipt of the permittee's NOI, and the 
    permittee will be responsible or meeting the discharge limitations of 
    Part A.1 or A.2. General Permit numbers will be assigned to these sites 
    and DMR's sent with a copy of the general permit and a letter 
    acknowledging receipt of the Notice of Intent.
        EPA responds to reasons # 2 and # 3 as proposed by the FDEP, which 
    would allow coverage by simply submitting an NOI for local departments 
    dewatering projects or scheduled dewatering during gasoline tank 
    replacements. It is EPA's understanding that the construction 
    activities described in No. 2 and No. 3 are planned well in advance of 
    the initiation of the dewatering process. For this reason, EPA sees no 
    reason to exempt these sites from NOI requirements. Unless preliminary 
    groundwater assessments have been performed along the right-of-way 
    project prior to startup, even the local departments may be unaware of 
    an contaminated plume that may be encountered during the road widening, 
    or excavation projects. The potential problem EPA expects in waiving 
    NOI requirements for these activities, is the lack of sufficient data 
    to cover these operations. The better approach would be for the 
    permittee to survey potential problem areas well in advance of the 
    dewatering startup, identify the type of contamination and seek 
    discharge coverage under the NPDES general permit using the NOI 
    process, for those potentially contaminated groundwater discharge 
    areas.
        Comment 3: FDEP also questioned whether the indicator criteria 
    values listed under Part I.A.3, should be analyzed using untreated 
    groundwater or treated groundwater. FDEP also stated that if the intent 
    of Part I.A.3 is to allow short term discharges from sites contaminated 
    with petroleum only, then the indicators should be applied to treated 
    recovered groundwater, because if these indicators were applied to 
    untreated groundwater, this would preclude discharges from sites 
    contaminated with petroleum only. However, FDEP stated that applying 
    these indicator values to the treated effluent may allow treatment 
    alternatives that are capable of removing the metals listed and become 
    eligible to discharge under the general permit, since the indicator 
    values were not exceeded (even if the source of contamination was not 
    petroleum in nature).
        Response: EPA notes that the indicator values apply to untreated 
    representative groundwater samples from the vicinity of the proposed 
    produced groundwater discharge. These could be tests from monitoring 
    wells, recovery wells, or samples of produced groundwater taken prior 
    to any treatment and would not allow treatment alternatives capable of 
    removing metals to be covered by this general permit. It should be 
    emphasized that the intent of Part I.A.3 is to allow the discharge of 
    produced groundwater from an uncontaminated site activity. If the site 
    is contaminated with petroleum fuels, the permit refers back to Parts 
    I.A.1 or I.A.2.
        Comment 4: FDEP requested EPA's determination on a particular issue 
    before the finalization of the general permit. FDEP stated that many 
    petroleum sites are located in urban areas, and other possible sources 
    of contamination may be located in the vicinity of the petroleum site. 
    In these situations commingling of plumes from non-petroleum sites may 
    occur. It was noted that many sites performing Contamination Assessment 
    Reports (CARs) had detected low levels of TCE or PCE for many sites 
    which had a dry cleaner in the vicinity. FDEP stated that since these 
    solvents had similar characteristics and were volatile, most treatment 
    system designs based on permit effluent requirements for the petroleum 
    compounds will easily remove the PCE or TCE to non-detectable levels 
    without any oversizing of equipment or additional treatment processes. 
    FDEP stated that other compounds in relatively low concentrations from 
    off site sources should not preclude eligibility of the general permit 
    for the overall cleanup, which is to remediate the petroleum plume and 
    requested EPA's determination on the issue.
        Response: EPA in it's initial conception of the general permit, 
    only made specific reference to contamination from petroleum fuels and 
    referenced gasoline, aviation gas, diesel and jet-fuel. The intent in 
    issuing this general permit was to provide general permit coverage for 
    the discharge of treated petroleum contaminated groundwater. To cover 
    other sources of contamination will require additional research and 
    public participation. Because the general permit expired on July 16, 
    1994, EPA sees an urgency to reissue this permit; therefore, EPA may 
    consider this issue in the future through a permit modification. EPA, 
    after collecting sufficient information, may consider the inclusion of 
    other chemicals associated with dry cleaners in the near future, but 
    due to the lack of sufficient information, will not address it at this 
    time.
        Comment 5: Chevron Research and Technology Company, by letter dated 
    October 4, 1994, requested a copy of the NPDES Best Management Practice 
    (BMP) Guidance Document.
        Response: EPA sent the NPDES BMP Guidance document to Chevron on 
    October 13, 1994.
        Comment 6: Morgan, Lewis & Bockius (ML&B), Counselors at Law, by 
    letter dated October 15, 1994, made two comments concerning the permit. 
    ML&B mentioned that all references to Florida Administrative Code 
    Chapter 17-770, 17-302, or any other ``17-'' should be changed to 
    Chapter ``62-770, or 62- 302, and mentioned that Chapter ``62-'' is 
    where the current law is found. ML&B also mentioned that the Fact Sheet 
    should contain some discussion of discharge to ``surface waters'', the 
    triggering event. ML&B also mentioned that the permittee should know 
    where to go in order look up the definition of ``surface waters'' or 
    discharges to surface waters. Mentioned that these issues and basic 
    guidance thereon may ensure that all facilities obligated under the 
    general permit actually apply for coverage and discussion of this 
    significant jurisdictional issue in the Fact Sheet or permit itself 
    seems appropriate.
        Response: EPA refers the commentor to the Clean Water Act (CWA) 
    which requires that point source discharges of pollutants to waters of 
    the United States be covered by NPDES permits. The definition of 
    ``point source'' and ``waters of the U.S.'' can be found at 40 CFR 
    Section 122.2. Additionally, all references that refer to Florida 
    Administrative Code Chapter ``17'' will be changed to Florida 
    Administrative Code Chapter ``62.''
        Comment 7: Mobil Oil Corporation (MOC), by letter dated October 17, 
    1994, supported the reissuance of the general permit, since it is more 
    efficient and cost effective approach to permitting routine activity 
    than the individual permitting process. MOC raised several concerns on 
    the draft NPDES general permit concerning the new requirements of the 
    whole effluent toxicity (WET) tests. MOC stated that the need for WET 
    testing has not been established. It was stated that the Fact Sheet 
    cited that the chemical criteria was significantly more stringent than 
    Florida's water quality standards and MOC stated that meeting the 
    chemical criteria, coupled with the required treatment processes should 
    be more than adequate to protect aquatic life.
        Response: In response to MOC comment, EPA notes that the chemical 
    specific discharge limitations mentioned do provide adequate protection 
    to meet Florida's chemical specific water quality standards. However, 
    since previous toxicity monitoring tests did indicate that a number of 
    effluents were toxic, which is also a violation of Florida 
    Administrative Code (FAC) Section 17-4.244(3)(a), WET limits were 
    incorporated into the permit.
        Comment 8: MOC stated that if WET testing is required, the 
    procedure outlined in Part V should be modified. MOC stated that if the 
    compliance limit for WET testing is an LC50 > 100%, the requirement for 
    a full concentration test is not warranted and only a screening test 
    (control and 100% final effluent only) should be run to demonstrate 
    compliance.
        Response: Regarding Mobil's comment on the use of multiple 
    dilutions, per the EPA acute WET protocol manual (EPA/600/4- 90/027F) 
    cited in the September 19,1994 Federal Register notice, such dilutions 
    are recommended to assess NPDES compliance for all WET tests (pg. 47-
    48). They provide more information about the dose-response of the test, 
    increase the statistical power of the test, and decrease the inherent 
    variability found in conducting a single test concentration with a 
    control.
        Comment 9: MOC stated that there was no advantage to static-renewal 
    versus the static procedure for these discharges and recommended the 
    static procedure for these WET tests.
        Response: Regarding Mobil's comment that static tests only be 
    conducted, the EPA acute WET protocol manual (EPA/600/4-90/027F) cited 
    in the Federal Register notice above mandates the use of static renewal 
    tests for all tests exceeding 48 hr (pg. 57, 61, 65, 69). Because the 
    acute WET tests specified in this notice are 96-hrs. in duration, 
    static renewals tests must be conducted.
        Comment 10: MOC also recommended that the mandatory requirement 
    that recommended concurrent standard reference toxicant (SRT) testing 
    be removed, since this provides limited information on the quality of 
    the testing laboratory. MOC mentioned that requiring facilities to pay 
    for these studies, when they receive no benefit is inappropriate.
        Response: Regarding Mobil's comment on the required concurrent 
    standard reference toxicant (SRT) testing with each WET test, the 
    September 19,1994 Federal Register notice does allow for monthly SRT 
    results to be submitted in lieu of such concurrent tests. Regarding 
    Mobil's comment on requiring contract laboratories to conduct such SRT 
    testing, EPA does not currently have a national laboratory 
    certification program for WET. EPA does acknowledge that some states do 
    have such a certification program. Until a national certification 
    program is established, EPA must have some means to assess the quality 
    of a given laboratory's performance. The use of SRTs is one way of 
    making that assessment. EPA notes that permittees have the option of 
    using in-house capabilities to conduct such WET tests. However, when 
    permittees rely on outside laboratories to conduct WET tests for NPDES 
    compliance purposes, the use of SRTs is required. EPA disagrees with 
    Mobil's comment that such SRT tests have no benefit for the permittee. 
    On the contrary, such SRT testing serves to validate the quality and 
    precision of the WET tests conducted by the contract laboratory on 
    behalf of the permittee that are submitted to the permitting authority.
        Comment 11: MOC mentioned that facilities covered by the existing, 
    but expired general permit may be required to perform another testing 
    requirement, such a EPA 624 and 625 although this sampling was 
    performed for the existing general permit.
        Response: EPA does not agree that facilities already discharging 
    under the general permit be excluded from performing an additional test 
    analysis on the effluent using EPA methods 624 or 625 priority 
    pollutant scan. This requirement conforms with the reapplication data 
    necessary for individual permits in which a permittee is required to 
    retest the effluent to obtain accurate information which determine 
    possible changes in effluent characteristics. This priority pollutant 
    scan shall be performed within 60 days of startup of the produced water 
    discharge, or within 60 days after receipt of notification of coverage 
    from EPA for facilities currently discharging under the previous 
    general permit.
        Comment 12: Exxon Company (EC), by letter dated October 20, 1994, 
    stated that some risk-based analysis is an important element in 
    establishing water quality criteria for certain processes, and that the 
    proposed 1.0 ug/l benzene effluent limit appears to be absent of any 
    risk-based approach. EC stated that scientific data does not warrant 
    the restrictive 1.0 ug/l benzene effluent limit for release into 
    surface water and is even more stringent than that required under 
    Florida Administrative Code (FAC) 17-302.530 for Class I potable water 
    supplies and recommended that the national limit of 5.0 ug/l be 
    substituted as the benzene effluent limit.
        Response: EPA concurs that the 1.0 ug/l limit for benzene is more 
    stringent than Florida's water quality standards. The limitation for 
    benzene is based on the best treatment technology available and happens 
    to be more stringent than FAC 17-302.530(9)[4/25/94], Class I potable 
    water supplies which is 1.18 ug/l. The 1.0 ug/l limitation is also more 
    stringent than Florida Class III water quality standard, which requires 
    an annual average limitation of 71.28 ug/l for benzene. Therefore, 
    since technology has proven capable of consistently maintaining the 1.0 
    ug/l limitation for benzene and numerous permittees have consistently 
    designed treatment systems that meet the requirements of the NPDES 
    general permit, EPA will retain the benzene limit. In addition, 
    maintaining the 1.0 ug/l benzene limit complies with Section 402(o)(1) 
    of the Water Quality Act of 1987, which states that a permit may not be 
    renewed, reissued, or modified to contain effluent limitations which 
    are less stringent than the comparable effluent limitations in the 
    previous permit except in compliance with Section 303 (d)(4).
        Comment 13: Exxon Company (EC) mentioned that the acceptable pH for 
    treated effluent under the previous and proposed NPDES general permit 
    is 6.0-8.5 standard units (SUs), and mentioned that many lakes and 
    streams in Central and North Florida have a pH range of 5.0-6.0 SUs. EC 
    stated that many influent pH samples for remedial pump and treat 
    systems are also in this range and recommended reducing the allowed 
    lower limit from 6.0 to 5.5 SUs. Response: In response to EC comments, 
    the pH language in the current proposed draft permit does allow some 
    variation for pH depending on natural background of the receiving 
    water. However, this natural background data must be furnished to EPA 
    by the permittee in the initial NOI request; in order to be considered 
    in determining the pH range for the facility during the notification of 
    coverage request. It should be noted that the pH of the receiving 
    stream, not the influent or effluent, influences the pH permit limits.
        Comment 14: Exxon Company (EC) commented on Part I.A.3 concerning 
    the screen for metals that would indicate contamination from sources 
    other than petroleum fuels. EC mentioned that it is unwarranted to 
    require screening for additional metals that are not ordinarily 
    considered constituents of petroleum fuels as a basis for securing a 
    NPDES general permit for petroleum fuel contamination. EC mentioned 
    that if there is a cause for this additional screening at a particular 
    site, the regulatory processes in place will generate the additional 
    site investigation and testing needed, instead of testing every site 
    whether justified or not and recommended that the screening for other 
    metals be removed as a requirement from the NPDES general permit. EC 
    mentioned that if additional metal testing is required, annual testing 
    is much more appropriate than semi-annual, especially for groundwater 
    remedial systems at underground storage tank cleanup sites.
        Response: In response to Exxon Company (EC) comments, EPA clarifies 
    the misconception that contaminated petroleum fuel sites must perform 
    the Part I.A.3 testing requirements for metals; these discharges must 
    comply only with the requirements of Part I.A.1 or I.A.2. EPA refers to 
    the general applicability of Part I.A.3, that allows produced water 
    discharges from any noncontaminated site, which could include 
    dewatering for tank removals, construction activity, or aquifer pump 
    tests from water wells. Any point source discharge of pollutants to 
    waters of the U.S. requires an NPDES permit, regardless of whether the 
    site is contaminated or uncontaminated. EPA, in its approach to 
    covering dewatering of produced groundwater associated with any 
    activity, placed the burden for verification on the permittee for 
    determining that the site groundwater has not been contaminated with 
    sources other than petroleum fuels. Requiring all permittees to perform 
    this screening allows facilities performing dewatering activities to be 
    placed under the general permit, assuming that the screening reveals no 
    contamination from sources other than petroleum fuels.
        Comment 15: Exxon Company (EC) mentioned that the Discharge 
    Monitoring Report forms should be revised and the reporting procedure 
    should be simplified. Also, mentioned that the quality of forms 
    initially received from EPA tend to become illegible when photocopied. 
    EC also requested that EPA retain the current level of bioassay testing 
    instead of increasing the frequency as proposed.
        Response: EPA will send original Discharge Monitoring Reports to 
    the permittee so that more legible photocopies can be produced. EPA 
    recommends that these originals be maintained by the permittee for 
    copying purposes. In reference to the bioassay requirements, permittees 
    which have previously obtained coverage under this general permit, 
    which effluents have not demonstrated unacceptable toxicity (LC 50 < 100%),="" may="" continue="" to="" sample="" 1/year.="" all="" sampling="" procedures="" and="" test="" methods="" must=""

        An LC50 of 100% or less in a test of 96 hours duration or less 
    will constitute a violation of Florida Administrative Code (FAC) (July 
    11, 1993) Sec. 62-4.244(3)(a) and the terms of this permit. The testing 
    for this requirement must conform with Part V of this permit.
        For fresh waters and coastal waters, the pH of the effluent shall 
    not be lowered to less than 6.0 units for fresh waters, or less than 
    6.5 units for marine waters, or raised above 8.5 units, unless the 
    permittee submits natural background data in the NOI request confirming 
    a natural background pH outside of this range. If natural background of 
    the receiving water, as revealed by sampling data from the permittee in 
    the NOI request, is determined to be less than 6.0 units for fresh 
    waters, or less than 6.5 units in marine waters, the pH shall not vary 
    below natural background or vary more than one (1) unit above natural 
    background for fresh and coastal waters. If natural background of the 
    receiving water, as revealed by sampling data from the permittee in the 
    NOI request, is determined to be higher than 8.5 units, the pH shall 
    not vary above natural background or vary more than one (1) unit below 
    natural background of fresh and coastal waters. The acceptable pH range 
    will be included in the letter granting permit coverage and on the DMR. 
    The pH shall be monitored once every month by grab sample, or 
    continuously with a recorder. (See item I.B.4).
        In accordance with FAC Sec. 62-302.500(1)(a-c)(4-25-93), the 
    discharge shall at all times be free from floating solids, visible 
    foam, turbidity, or visible oil in such amounts as to form nuisances on 
    surface waters.
        Samples taken in compliance with the monitoring requirements 
    specified above shall be taken at the following location(s): Nearest 
    accessible point after final treatment but prior to actual discharge or 
    mixing with the receiving waters.

    and New Dischargers
    
        2. During the period beginning on the effective date of the permit 
    and lasting through the term of this permit, the permittee is 
    authorized to discharge treated groundwater and storm water that has 
    been contaminated by Aviation Gasoline, Jet Fuel or Diesel.
        It is anticipated that these contaminated waters will be treated by 
    air stripping, followed by activated carbon adsorption, if necessary, 
    or equivalent treatment to meet the following effluent limitations. 
    Such discharges shall be limited and monitored by the permittee as 
    specified below:

    A. Effluent Limitations and Monitoring Requirements
    
        3. During the period beginning on the effective date of the permit 
    and lasting through the term of this permit, the permittee is 
    authorized to discharge produced groundwater from any noncontaminated 
    site activity which discharges by a point source to waters of the 
    United States, only if the reported values for the parameters listed 
    below do not exceed any of the screening values below. Before discharge 
    of produced groundwater can occur from such sites, analytical tests on 
    samples of the untreated proposed discharge water shall be performed to 
    determine if contamination exists from other sources.
        The following are the minimum reporting requirements for all 
    produced groundwater dischargers which have acceptable screening value 
    results as described below:
        The effluent shall be sampled at the final effluent within thirty 
    (30) days after commencement of discharge and once every six months for 
    the life of the project to maintain continued coverage under this 
    general permit. The effluent shall be sampled for the parameters listed 
    below and the analytical results obtained shall be submitted to EPA at 
    the address given in Part III.A.

        If at any time during discharge, the effluent exceeds these 
    screening values, EPA may require the facility to cease discharge.
        If any of the analytical test results, (except TOC, benzene or 
    naphthalene), exceed the above screening values, discharge is not 
    authorized by this permit. See paragraph I.A.(3)(b) for further 
    guidance.
        For excessive benzene or naphthalene concentrations, see Part 
    A.(3)(a) below. For initial excessive TOC values that may be caused by 
    naturally-occurring, high molecular weight organic compounds, the 
    permittee may request to be exempted from the TOC requirement by 
    submitting additional information with the NOI which describes the 
    method used to exclude these naturally ocurring compounds.
        In accordance with FAC 62-302.500(1)(a-c), the discharge shall at 
    all times be free from floating solids, visible foam, turbidity, or 
    visible oil in such amounts as to form nuisances on surface waters.
        All discharges must comply with the following permit requirements:
        (a) If analytical tests of Part I.A.3 reveal excessive benzene and 
    naphthalene concentrations indicative of contamination from petroleum 
    fuels, and the discharge will occur for thirty (30) days or less, the 
    permittee shall comply only with the applicable effluent limitations 
    and monitoring requirements in Part I.A.1 or I.A.2 for benzene, pH, 
    and/or naphthalene and total lead. The commencement of the Part V 
    biomonitoring program and Part I.B.3 EPA method 624 and 625 (one time 
    analysis) is not required for this short-term activity. One (1) grab 
    sample shall be analyzed per seven (7) days during the discharge 
    period, and the total volume discharged shall be recorded. For 
    discharges contaminated by petroleum fuels that last for less than a 
    week, daily monitoring will be required for the applicable parameters. 
    Upon receipt of written EPA notification of coverage that the NOI 
    request is complete, these short-term discharges may commence. 
    Discharge Monitoring Reports shall be submitted to EPA within thirty 
    (30) days after termination of the discharge.
        (b) If contamination from sources other than petroleum 
    contamination does exist, as indicated by the results of the analytical 
    tests required by Part I. A.3 above, the discharge is not covered by 
    this general permit. The operator shall apply for an individual NPDES 
    permit at least one hundred and twenty (120) days prior to the date a 
    discharge to waters of the United States is expected. No discharge is 
    permissible without an effective NPDES permit.
        (c) If analytical tests reveal no contamination exists from 
    petroleum fuels or sources other than petroleum contamination as a 
    result of the required analytical screening tests required in Part I. 
    A.3, the permittee can commence discharge immediately and is covered by 
    this permit without having to submit an NOI request for coverage to 
    EPA, Region IV. A short summary of the proposed activity and copy of 
    these analytical tests shall be sent to the same address specified in 
    Part III.A one (1) week after discharge begins. These analytical tests 
    shall be kept on site during discharge and made available to EPA, if 
    requested. Additionally, no Discharge Monitoring Report (DMR) forms are 
    required to be submitted to EPA, Region IV.
    
    B. Other Requirements
    
        1. Any more frequent effluent discharge monitoring required by the 
    Florida Department of Environmental Protection (FDEP) for the 
    parameters limited in this permit, or different parameters, shall be 
    reported to the Permit Issuing Authority in accordance with the 
    requirements of Part III of this permit.
        2. Effluent limitations for combining contaminated groundwater 
    pumped to above-ground storage tanks with contaminated groundwater from 
    the site's recovery wells: The permittee shall notify FDEP of any 
    intent to combine contaminated groundwater pumped to above-ground 
    storage tanks with contaminated groundwater from the recovery well. 
    Approval of this combined effluent discharge by FDEP will constitute 
    approval to apply for coverage under this permit.
        3. Within sixty (60) days of the effective date of this permit or 
    startup of discharge the permittee shall also submit the results of the 
    following analyses. These analyses shall be performed on a 
    representative sample of the groundwater effluent discharge, taken 
    after final treatment.
        Required analyses (one time only):
    
    a. EPA Method 625--Acid and base/neutral extractable organics
    b. EPA Method 624--Purgeable Organics
    
        If such analyses required in Part B.3 above reveal toxic pollutants 
    other than those regulated in Part I.A. or subsequent Whole Effluent 
    Toxicity (WET) tests reveal an LC50 of 100% or less in a test of 
    96 hours duration or less, coverage under this general permit will be 
    reviewed for termination by EPA Region IV Enforcement Section.
        4. If the pH is monitored continuously, the pH values shall not 
    deviate outside the required range more than 1% of the time in any 
    calendar month; and no individual excursion shall exceed 60 minutes. An 
    ``excursion'' is an unintentional and temporary incident in which the 
    pH value of discharge wastewater exceeds the range set forth in this 
    permit.
    
    C. Test Procedures
    
        1. In performing the analysis for the dissolved constituents in the 
    surface water and groundwater, the permittee shall use the guidelines 
    recommended and described in FAC Sections 62-770.600(8)[a-d] of the 
    Petroleum Contamination Cleanup Criteria (PCCC), amended February 20, 
    1990, or the most current edition.
        2. If the petroleum contamination is from a petroleum fuel in which 
    the source of contamination has not been identified, the groundwater 
    shall be analyzed (using the recommended methods) for the following 
    parameters as described in FAC Section 62.770.600(8)(c)1, of the PCCC, 
    amended February 20, 1990, or the most current edition:
    
    
    a. Lead.......................................  (EPA Method 239.2 or    
                                                     Standard Method 304)   
    b. Priority Pollutant Volatile Organics.......  (EPA Method 624)        
    c. Priority Pollutant Extractable Organics....  (EPA Method 625)        
    d. Non-Priority Pollutant Organics (with GC/MS  (EPA Methods 624 and    
     Peaks greater than 10 ppb).                     625)                   
                                                                            
    
    D. Schedule of Compliance
    
        1. The permittee shall achieve compliance with the effluent 
    limitations specified for discharges in accordance with the following 
    schedule:
        Permittees with Revoked Individual Permits:
    
    Operational level attained--Upon Receipt of Notification of Coverage 
        New Dischargers:
    Operational level attained--Upon Commencement of Discharge
    
        2. No later than fourteen (14) calendar days after any date 
    identified in the above schedule of compliance the permittee shall 
    submit either a report of progress or, in the case of specific actions 
    being required by identified dates, a written notice of compliance or 
    noncompliance. In the latter case, the notice shall include the cause 
    of noncompliance, any remedial actions taken, and the probability of 
    meeting the next scheduled requirement.
    
    Part II
    
    Standard Conditions for NPDES Permits
    
    Section A. General Conditions
    
    1. Duty to Comply
        The permittee must comply with all conditions of this permit. Any 
    permit noncompliance constitutes a violation of the Clean Water Act and 
    is grounds for enforcement action; for permit termination, revocation 
    and reissuance, or modification; or for denial of a permit renewal 
    application.
    2. Penalties for Violations of Permit Conditions
        Any person who violates a permit condition is subject to a civil 
    penalty not to exceed $25,000 per day of such violation. Any person who 
    willfully or negligently violates permit conditions is subject to a 
    fine of up to $50,000 per day of violation, or by imprisonment for not 
    more than 1 year, or both. Any person who knowingly violates permit 
    conditions is subject to criminal penalties of $5,000 to 50,000 per day 
    of violation, or imprisonment for not more than 3 years, or both. Also, 
    any person who violates a permit condition may be assessed an 
    administrative penalty not to exceed $10,000 per violation with the 
    maximum not to exceed $125,000. [Ref: CFR 122.41(a)].
    3. Duty to Mitigate
        The permittee shall take all reasonable steps to minimize or 
    prevent any discharge in violation of this permit which has a 
    reasonable likelihood of adversely affecting human health or the 
    environment.
    4. Duty to Reapply
        Where EPA is the Permit Issuing Authority (PIA), the terms and 
    conditions of this permit are automatically continued in accordance 
    with 40 CFR 122.6, only where the permittee has submitted a timely and 
    complete Notice of Intent 180 days prior to expiration of this permit, 
    and the PIA is unable through no fault of the permittee to issue a new 
    permit before the expiration date.
    5. Permit Modification
        After notice and opportunity for a hearing, this permit may be 
    modified, terminated, or revoked for cause (as described in 40 CFR 
    122.62 et seq) including, but not limited to, the following:
        a. Violation of any terms or conditions of this permit;
        b. Obtaining this permit by misrepresentation or failure to 
    disclose fully all relevant facts;
        c. A change in any conditions that requires either temporary 
    interruption or elimination of the permitted discharge; or
        d. Information newly acquired by the Agency indicating the 
    discharge poses a threat to human health or welfare.
        If the permittee believes that any past or planned activity would 
    be cause for modification or revocation and reissuance under 40 CFR 
    122.62, the permittee must report such information to the Permit 
    Issuing Authority. The submittal of a new application may be required 
    of the permittee. The filing of a request by the permittee for a permit 
    modification, revocation and reissuance, or termination, or a 
    notification of planned changes or anticipated noncompliance, does not 
    stay any permit condition.
    6. Toxic Pollutants
        Notwithstanding Paragraph A-4, above, if a toxic effluent standard 
    or prohibition (including any schedule of compliance specified in such 
    effluent standard or prohibition) is established under Section 307(a) 
    of the Act for a toxic pollutant which is present in the discharge and 
    such standard or prohibition is more stringent than any limitation for 
    such pollutant in this permit, this permit shall be modified or revoked 
    and reissued to conform to the toxic effluent standard or prohibition 
    and the permittee so notified.
    7. Civil and Criminal Liability
        Except as provided in permit conditions on ``Bypassing'' Section B, 
    Paragraph B-3, nothing in this permit shall be construed to relieve the 
    permittee from civil or criminal penalties for noncompliance.
    8. Oil and Hazardous Substance Liability
        Nothing in this permit shall be construed to preclude the 
    institution of any legal action or relieve the permittee from any 
    responsibilities, liabilities, or penalties to which the permittee is 
    or may be subject under Section 311 of the Act.
    9. State Laws
        Nothing in this permit shall be construed to preclude the 
    institution of any legal action or relieve the permittee from any 
    responsibilities, liabilities, or penalties established pursuant to any 
    applicable State law or regulation under authority preserved by Section 
    510 of the Act.
    10. Property Rights
        The issuance of this permit does not convey any property rights of 
    any sort, or any exclusive privileges, nor does it authorize any injury 
    to private property or any invasion of personal rights, nor any 
    infringement of Federal, State or local laws or regulations.
    11. Severability
        The provisions of this permit are severable, and if any provision 
    of this permit, or the application of any provision of this permit to 
    any circumstance, is held invalid, the application of such provision to 
    other circumstances, and the remainder of this permit, shall not be 
    affected thereby.
    12. Duty to Provide Information
        The permittee shall furnish to the Permit Issuing Authority, within 
    a reasonable time, any information which the Permit Issuing Authority 
    may request to determine whether cause exists for modifying, revoking 
    and reissuing, or terminating this permit or to determine compliance 
    with this permit. The permittee shall also furnish to the Permit 
    Issuing Authority upon request, copies of records required to be kept 
    by this permit.
    
     Section B. Operation and Maintenance of Pollution Controls
    
    1. Proper Operation and Maintenance
    
        The permittee shall at all times properly operate and maintain all 
    facilities and systems of treatment and control (and related 
    appurtenances) which are installed or used by the permittee to achieve 
    compliance with the conditions of this permit. Proper operation and 
    maintenance also includes adequate laboratory controls and appropriate 
    quality assurance procedures. This provision requires the operation of 
    back-up or auxiliary facilities or similar systems which are installed 
    by a permittee only when the operation is necessary to achieve 
    compliance with the conditions of the permit.
    
    2. Need to Halt or Reduce Not a Defense
    
        It shall not be a defense for a permittee in an enforcement action 
    that it would have been necessary to halt or reduce the permitted 
    activity in order to maintain compliance with the condition of this 
    permit.
    
    3. Bypass of Treatment Facilities
    
    a. Definitions
        (1) ``Bypass'' means the intentional diversion of waste streams 
    from any portion of a treatment facility, which is not a designed or 
    established operating mode for the facility.
        (2) ``Severe property damage'' means substantial physical damage to 
    property, damage to the treatment facilities which causes them to 
    become inoperable, or substantial and permanent loss of natural 
    resources which can reasonably be expected to occur in the absence of a 
    bypass. Severe property damage does not mean economic loss caused by 
    delays in production.
    b. Bypass Not Exceeding Limitations
        The permittee may allow any bypass to occur which does not cause 
    effluent limitations to be exceeded, but only if it also is for 
    essential maintenance to assure efficient operation. These bypasses are 
    not subject to the provisions of Paragraphs c. and d. of this section.
    c. Notice
        (1) Anticipated bypass. If the permittee knows in advance of the 
    need for a bypass, it shall submit prior notice, if possible at least 
    ten days before the date of the bypass; including an evaluation of the 
    anticipated quality and effect of the bypass.
        (2) Unanticipated bypass. The permittee shall submit notice of an 
    unanticipated bypass as required in Section D, Paragraph D-4 (24-hour 
    notice).
    d. Prohibition of Bypass
        (1) Bypass is prohibited and the Permit Issuing Authority may take 
    enforcement action against a permittee for bypass, unless:
        (a) Bypass was unavoidable to prevent loss of life, personal 
    injury, or severe and extensive property damage;
        (b) There were no feasible alternatives to the bypass, such as 
    maintenance of sufficient reserve holding capacity, the use of 
    auxiliary treatment facilities, retention of untreated wastes, waste 
    hauling, or maintenance during normal periods of equipment downtime. 
    This condition is not satisfied if adequate back-up equipment should 
    have been installed in the exercise of reasonable engineering judgment 
    to prevent a bypass which occurred during normal periods of equipment 
    downtime or preventive maintenance; and
        (c) The permittee submitted notices as required under Paragraph c. 
    of this section.
        (2) The Permit Issuing Authority may, within its authority, approve 
    an anticipated bypass, after considering its adverse effects, if the 
    Permit Issuing Authority determines that it will meet the three 
    conditions listed above in Paragraph d.(1) of this section.
    
    4. Upsets
    
        ``Upset'' means an exceptional incident in which there is 
    unintentional and temporary noncompliance with technology based permit 
    effluent limitations because of factors beyond the control of the 
    permittee. An upset does not include noncompliance to the extent caused 
    by operational error, improperly designed treatment facilities, 
    inadequate treatment facilities, lack of preventive maintenance, or 
    careless or improper operation. An upset constitutes an affirmative 
    defense to an action brought for noncompliance with such technology 
    based permit limitation if the requirements of 40 CFR 122.41(n)(3) are 
    met. (Note that this provision does not apply to water quality 
    requirements.)
    
    5. Removed Substances
    
        This permit does not authorize discharge of solids, sludge, filter 
    backwash, or other pollutants removed in the course of treatment or 
    control of wastewaters to waters of the United States unless 
    specifically limited in Part 1.
    
    Section C. Monitoring and Records
    
    1. Representative Sampling
    
        Samples and measurements taken as required herein shall be 
    representative of the volume and nature of the monitored discharge. All 
    samples shall be taken at the monitoring points specified in this 
    permit and, unless otherwise specified, before the effluent joins or is 
    diluted by any other wastestream, body of water, or substance. 
    Monitoring points shall not be changed without notification to and the 
    approval of the Permit Issuing Authority.
    
    2. Flow Measurements
    
        Appropriate flow measurement devices and methods consistent with 
    accepted scientific practices shall be selected and used to insure the 
    accuracy and reliability of measurements of the volume of monitored 
    discharges. The devices shall be installed, calibrated and maintained 
    to insure that the accuracy of the measurements are consistent with the 
    accepted capability of that type of device. Devices selected shall be 
    capable of measuring flows with a maximum deviation of less than 
     10% from the true discharge rates throughout the range of 
    expected discharge volumes. Guidance in selection, installation, 
    calibration and operation of acceptable flow measurement devices can be 
    obtained from the following references:

        Monitoring must be conducted according to test procedures approved 
    under 40 CFR Part 136, unless other test procedures have been specified 
    in this permit.
    
    4. Penalties for Tampering
    
        The Clean Water Act provides that any person who falsifies, tampers 
    with, or knowingly renders inaccurate, any monitoring device or method 
    required to be maintained under this permit shall, upon conviction, be 
    punished by a fine of not more than $10,000 per violation, or by 
    imprisonment for not more than 2 years per violation, or by both.
    
    5. Retention of Records
    
        The permittee shall retain records of all monitoring information, 
    including all calibration and maintenance records and all original 
    strip chart recordings for continuous monitoring instrumentation, 
    copies of all reports required by this permit, and records of all data 
    used to complete the application for this permit, for a period of at 
    least 3 years from the date of the sample, measurement, report or 
    application. This period may be extended by the Permit Issuing 
    Authority at any time.
    
    6. Record Contents
    
        Records of monitoring information shall include:
        a. The date, exact place, and time of sampling or measurements;
        b. The individual(s) who performed the sampling or measurements;
        c. The date(s) analyses were performed;
        d. The individual(s) who performed the analyses;
        e. The analytical techniques or methods used; and
        f. The results of such analyses.
    
    7. Inspection and Entry
    
        The permittee shall allow the Permit Issuing Authority, or an 
    authorized representative, upon the presentation of credentials and 
    other documents as may be required by law, to:
        a. Enter upon the permittee's premises where a regulated facility 
    or activity is located or conducted, or where records must be kept 
    under the conditions of this permit;
        b. Have access to and copy, at reasonable times, any records that 
    must be kept under the conditions of this permit;
        c. Inspect at reasonable time any facilities, equipment (including 
    monitoring and control equipment), practices, or operations regulated 
    or required under this permit; and
        d. Sample or monitor at reasonable times, for the purposes of 
    assuring permit compliance or as otherwise authorized by the Clean 
    Water Act, any substances or parameters at any location.
    
    Section D. Reporting Requirements
    
    1. Change in Discharge
    
        The permittee shall give notice to the Permit Issuing Authority as 
    soon as possible of any planned physical alterations or additions to 
    the permitted facility. Notice is required only when:
        a. The alteration or addition to a permitted facility may meet one 
    of the criteria for determining whether a facility is a new source; or
        b. The alteration or addition could significantly change the nature 
    or increase the quantity of pollutants discharged. This notification 
    applies to pollutants which are subject neither to effluent limitations 
    in the permit, nor to notification requirements under Section D, 
    Paragraph D-10(a).
    
    2. Anticipated Noncompliance
    
        The permittee shall give advance notice to the Permit Issuing 
    Authority of any planned change in the permitted facility or activity 
    which may result in noncompliance with permit requirements. Any 
    maintenance or facilities, which might necessitate unavoidable 
    interruption of operation and degradation of effluent quality, shall be 
    scheduled during noncritical water quality periods and carried out in a 
    manner approved by the Permit Issuing Authority.
    
    3. Transfer of Ownership or Control
    
        A permit may be automatically transferred to another party if:
        a. The permittee notifies the Permit Issuing Authority of the 
    proposed transfer at least 30 days in advance of the proposed transfer 
    date;
        b. The notice includes a written agreement between the existing and 
    new permittees containing a specific date for transfer of permit 
    responsibility, coverage, and liability between them; and
        c. The Permit Issuing Authority does not notify the existing 
    permittee of his or her intent to modify or revoke and reissue the 
    permit. If this notice is not received, the transfer is effective on 
    the date specified in the agreement mentioned in paragraph b.
    
    4. Monitoring Reports
    
        See Part III of this permit.
    
    5. Additional Monitoring by the Permittee
    
        If the permittee monitors any pollutant more frequently than 
    required by this permit, using test procedures approved under 40 CFR 
    136 or as specified in this permit, the results of this monitoring 
    shall be included in the calculation and reporting of the data 
    submitted in the Discharge Monitoring Report (DMR). Such increased 
    frequency shall also be indicated.
    
    6. Averaging of Measurements
    
        Calculations for limitations which require averaging of 
    measurements shall utilize an arithmetic mean unless otherwise 
    specified by the Permit Issuing Authority in the permit.
    
    7. Compliance Schedules
    
        Reports of compliance or noncompliance with, or any progress 
    reports on, interim and final requirements contained in any compliance 
    schedule of this permit shall be submitted no later than 14 days 
    following each schedule date. Any reports of noncompliance shall 
    include the cause of noncompliance, any remedial actions taken, and the 
    probability of meeting the next scheduled requirement.
    
    8. Twenty-Four Hour Reporting
    
        The permittee shall orally report any noncompliance which may 
    endanger health or the environment, within 24 hours from the time the 
    permittee becomes aware of the circumstances. A written submission 
    shall also be provided within 5 days of the time the permittee becomes 
    aware of the circumstances. The written submission shall contain a 
    description of the noncompliance and its cause, the period of 
    noncompliance, including exact dates and times; and if the 
    noncompliance has not been corrected, the anticipated time it is 
    expected to continue, and steps taken or planned to reduce, eliminate, 
    and prevent reoccurrence of the noncompliance. The Permit Issuing 
    Authority may verbally waive the written report, on a case-by-case 
    basis, when the oral report is made. The following violations shall be 
    included in the 24 hour report when they might endanger health or the 
    environment:
        a. An unanticipated bypass which exceeds any effluent limitation in 
    the permit.
        b. Any upset which exceeds any effluent limitation in the permit.
    
    9. Other Noncompliance
    
        The permittee shall report in narrative form, all instances of 
    noncompliance not previously reported under Section D, Paragraphs D-2, 
    D-4, D-7, and D-8 at the time monitoring reports are submitted. The 
    reports shall contain the information listed in Paragraph D-8.
    
    10. Changes in Discharges of Toxic Substances
    
        The permittee shall notify the Permit Issuing Authority as soon as 
    it knows or has reason to believe:
        a. That any activity has occurred or will occur which would result 
    in the discharge, on a routine or frequent basis, of any toxic 
    substance(s) (listed at 40 CFR 122, Appendix D, Table II and III) which 
    is not limited in the permit, if that discharge will exceed the highest 
    of the following ``notification levels'':
        (1) One hundred micrograms per liter (100 ug/l); or
        (2) Two hundred micrograms per liter (200 ug/l) for acrolein and 
    acrylonitrile; five hundred micrograms per liter (500 ug/l) for 2, 4-
    dinitrophenol and for 2-methyl-4, 6-dinitrophenol; and one milligram 
    per liter (1 mg/l) for antimony.
        b. That any activity has occurred or will occur which would result 
    in any discharge, on a non-routine or infrequent basis, of a toxic 
    pollutant (listed at 40 CFR 122, Appendix D. Table II and III) which is 
    not limited in the permit, if that discharge will exceed the highest of 
    the following ``notification levels'':
        (1) Five hundred micrograms per liter (500 ug/l); or
        (2) One milligram per liter (1 mg/l) for antimony.
    
    11. Signatory Requirements
    
        All applications, reports, or information submitted to the Permit 
    Issuing Authority shall be signed and certified.

    permit, including monitoring reports or reports of compliance or 
    noncompliance shall, upon conviction, be punished by a fine of not more 
    than $10,000 per violation, or by imprisonment for not more than 2 
    years per violation, or by both.
    
    Section E. Definitions
    
    1. Permit Issuing Authority
    
        The Regional Administrator of EPA Region IV or his designee, unless 
    at some time in the future the State receives the authority to 
    administer the NPDES program and assumes jurisdiction over the permit; 
    at which time, the Director of the State program receiving 
    authorization becomes the issuing authority.
    
    2. Act
    
        ``Act'' means the Clean Water Act (formerly referred to as the 
    Federal Water Pollution Control Act) Public Law 92-500, as amended by 
    Public Laws 95-217, 95-576, 96-483, 97-117, and Public Law 100-4, 33 
    U.S.C. 1251 et seq.
    
    3. Concentration Measurements
    
        a. The ``average monthly concentration'', is the sum of the 
    concentrations of all daily discharges sampled and/or measured during a 
    calendar month on which daily discharges are sampled and measured, 
    divided by the number of daily discharges sampled and/or measured 
    during such month (arithmetic mean of the daily concentration values). 
    The daily concentration value is equal to the concentration of a 
    composite sample or in the case of grab samples is the arithmetic mean 
    (weighted by flow value) of all the samples collected during the 
    calendar day.
        b. The ``maximum daily concentration'', is the concentration of a 
    pollutant discharge during a calendar day. It is identified as ``Daily 
    Maximum'' under ``Other Limits'' in Part I of the permit and the 
    highest such value recorded during the reporting period is reported 
    under the ``Maximum'' column under ``Quality'' on the DMR.
    
    4. Other Measurements
    
        a. The effluent flow expressed as MGD is the 24 hour average flow 
    averaged monthly. It is the arithmetic mean of the total daily flows 
    recorded during the calendar month. Where monitoring requirements for 
    flow are specified in Part I of the permit the flow rate values are 
    reported in the ``Average'' column under ``Quantity'' on the DMR.
        b. An ``instantaneous flow measurement'' is a measure of flow taken 
    at the time of sampling, when both the sample and flow will be 
    representative of the total discharge.
        c. Where monitoring requirements for pH or dissolved oxygen are 
    specified in Part I of the permit, the values are generally reported in 
    the ``Quality or Concentration'' column on the DMR.
    
    5. Types of Samples
    
        a. Grab Sample: A ``grab sample'' is a single influent or effluent 
    portion which is not a composite sample. The sample(s) shall be 
    collected at the period(s) most representative of the total discharge.
    
    6. Calendar Day
    
        A calendar day is defined as the period from midnight of one day 
    until midnight of the next day. However, for purposes of this permit, 
    any consecutive 24-hour period that reasonably represents the calendar 
    day may be used for sampling.
    
    7. Hazardous Substance
    
        A hazardous substance means any substance designated under 40 CFR 
    Part 116 pursuant to Section 311 of the Clean Water Act.
    
    8. Toxic Pollutant
    
        A toxic pollutant is any pollutant listed as toxic under Section 
    307(a)(1) of the Clean Water Act.
    
    Section F. Application Requirements
    
        a. For expired individual NPDES permits, dischargers desiring 
    coverage under this general permit are required to submit a notice of 
    intent (NOI) to the Permit Issuing Authority. The NOI shall include (1) 
    the name and address of the person that the permit will be issued to 
    (2) the name, and address of the operation, including county location, 
    (3) the applicable individual NPDES number(s), (4) the identification 
    of any new discharge location not contained in the expired permit, (5) 
    evidence that the operation has obtained approval of a Remedial Action 
    Plan (RAP) Order from the FDEP, (6) a map showing the facility and 
    discharge location (including latitude and longitude), (7) the name of 
    the receiving water, and (8) for discharges lasting over one (1) year a 
    pollution prevention plan. (See Part IV.2) Operators having several 
    individual permits are encouraged to consolidate requests for coverage 
    into one NOI for all individual permits. The previous submission of the 
    proper forms in the renewal application does not relieve the permittee 
    desiring coverage under the general permit of the requirement to file a 
    NOI.
        b. All facilities continued by the previous general permit, will be 
    required to submit a NOI requesting continued coverage under the 
    reissued general permit by [insert date 60 calendar days after the date 
    of publication in the Federal Register]. The NOI shall contain the same 
    information specified in paragraph a above.
        c. Dischargers with current individual NPDES permits that desire 
    coverage under this general permit are required to file an NOI to the 
    Permit Issuing Authority at least thirty (30) days prior to expiration 
    of their current permit(s). The NOI shall contain the same information 
    specified in paragraph a above. Permittees desiring to renew their 
    individual permit are required to submit the appropriate application 
    forms at least 180 days before expiration of their individual permit.
        d. Dischargers who have not previously obtained an individual NPDES 
    permit are required to submit to EPA the FDEP approval order letter 
    approving the site RAP. The RAP approval order shall be attached to an 
    NOI to be covered by the general permit and shall contain the same 
    information specified in paragraph (a) above. The application for 
    coverage under the general permit must be made at least fourteen (14) 
    days before the discharge is to commence.
        e. Dischargers seeking coverage under Part I A.3.a. will be 
    required to submit to EPA the date the discharge is expected to cease, 
    results of analytical data and the same information in paragraph a 
    above, except items (3), (4), (5) and (8). Notification of coverage to 
    discharge will be upon receipt of EPA's short-term coverage letter.
        f. Notification of coverage will be given by the Permit Issuing 
    Authority by certified mail to the permittee (except for short-term 
    pump tests, 8-hours in duration or less), for dischargers seeking 
    coverage under Part I Sections A.1 and A.2, with the issuance date for 
    each facility being the effective date of coverage by the Permit 
    Issuing Authority.
        Short-term pump tests, shall be covered automatically once the 
    permittee receives acceptable groundwater screening values, and the 
    permittee will be responsible meeting the requirements of Parts I.A.1 
    or A.2. The DMR's for these pump tests shall be submitted to within 
    thirty (30) days after discharge ceases.
        g. Dischargers meeting the conditions set forth in Part I A.3.c. 
    are not required to submit an detailed NOI as outlined above, but must 
    submit a copy of the analytical tests and a summary of the proposed 
    activity one (1) week after discharge begins. These dischargers are 
    covered upon receipt of the data, unless notified otherwise by EPA.
        h. The coverage of the permit shall expire on December 6, 1999.
        i. In accordance with 40 CFR 122.28(a)(2) permittees who are 
    covered by this general permit who seek to be continued under this 
    general permit, shall submit an complete NOI in accordance with 
    paragraph a, to EPA 180 days before the expiration of this permit.
    
    Section G. Additional General Permit Conditions
    
        1. The Permit Issuing Authority may require any person authorized 
    by this permit to apply for and obtain an individual NPDES permit when:
        a. The discharge(s) is a significant contributor of pollution;
        b. The discharger is not in compliance with the conditions of this 
    permit;
        c. A change has occurred in the availability of the demonstrated 
    technology of practices for the control or abatement of pollutants 
    applicable to the point sources;
        d. Effluent limitation guidelines are promulgated for point sources 
    covered by this permit;
        e. A Water Quality Management Plan containing requirements 
    applicable to such point source is approved; or
        f. The point source(s) covered by this permit no longer:
        (1) Involve the same or substantially similar types of operations;
        (2) Discharge the same types of wastes;
        (3) Require the same effluent limitations or operating conditions;
        (4) Require the same or similar monitoring; and
        (5) In the opinion of the RA, are more appropriately controlled 
    under an individual permit than under a general permit. The Regional 
    Administrator (RA) may require any operator authorized by this permit 
    to apply for an individual NPDES permit only if the operator has been 
    notified in writing that a permit application is required.
        2. Any operator authorized to discharge by this permit may request 
    to be excluded from the coverage of this general permit by applying for 
    an individual permit. The operator shall submit an application together 
    with the reasons supporting the request to the RA.
        3. When an individual NPDES permit is issued to an operator 
    otherwise subject to this general permit, the applicability of this 
    permit to the owner or operator is automatically terminated on the 
    effective date of the individual permit.
        4. A source excluded from coverage under this general permit solely 
    because it already has an individual permit may request that its 
    individual permit be revoked, and that it be covered by this general 
    permit. Upon revocation of the individual permit, this general permit 
    shall apply to the source.
        5. A petroleum contamination recovery operation may be excluded 
    from this general permit if it proposes discharges to receiving waters 
    that are classified as ``Special Protection, Outstanding Florida 
    Waters, Outstanding National Resource Waters'' as set forth by FAC 62-
    302.700, dated April 25, 1993.
        6. The permittee shall notify the Permit Issuing Authority within 
    30 days after the permanent termination of discharge from their 
    facility. This letter shall include the necessary Site Rehabilitation 
    Completion Order (SRCO) from Florida Bureau of Waste Cleanup which 
    constitutes final action on the State level for completion of cleanup 
    activities at the affected site. After review of the SRCO, EPA will 
    inactivate coverage of the general NPDES permit for the facility. 
    Dischargers covered under this general permit without RAP approval 
    shall submit a No Discharge Certification Form to EPA, within 30 days 
    after ceasing discharge.
    
    Part III
    
    Other Requirements
    
    A. Reporting of Monitoring Results
    
        Monitoring results obtained for each calendar month shall be 
    summarized and reported on a DMR Form (EPA No. 3320-1), one DMR for 
    each month. Unless otherwise required in Part V, these forms shall be 
    submitted after each calendar quarter and postmarked no later than the 
    28th day of the month following the completed calendar quarter. (For 
    example, data for January-March shall be submitted by April 28.) 
    Calendar quarters are January-March, April-June, July-September and 
    October-December. Signed copies of these and all other reports required 
    by Section D of Part II, Reporting Requirements, and Part V shall be 
    submitted to the Permit Issuing Authority at the following address: 
    U.S. Environmental Protection Agency, Region IV, Enforcement Section, 
    Water Permits and Enforcement Branch, 345 Courtland Street, N.E., 
    Atlanta, GA 30365.
        If no discharge occurs during the reporting period, sampling 
    requirements of this permit do not apply. The statement ``No 
    Discharge'' shall be written on the DMR form. If, during the term of 
    this permit, the facility ceases discharge to surface waters, the 
    Permit Issuing Authority shall be notified immediately upon cessation 
    of discharge.
    
    B. Reopener Clause
    
        This permit shall be modified, or alternatively revoked and 
    reissued to comply with any applicable effluent standard or limitation 
    issued or approved under Sections 301(b)(2)(C), and (D), 304(b)(2), and 
    307(a)(2) of the Clean Water Act (the Act), if the effluent standard or 
    limitation so issued or approved--
        1. Contains different conditions or is otherwise more stringent 
    than any condition in this permit; or
        2. Controls any pollutant not limited in the permit. The permit as 
    modified or reissued under this paragraph shall also contain any other 
    requirements of the Act then applicable.
    
    Part IV
    
    Best Management Practices and Pollution Prevention Conditions
    
    Section A. General Conditions
    
    1. BMP Plan
        Preparation of a Best Management Practices (BMP) Plan shall be 
    prepared in conjunction with development of the Remedial Action Plan 
    required by Florida Department of Environmental Protection (See Part 
    II.F.c.). The permittee shall maintain the BMP plan at the facility and 
    shall make the plan available to the permit issuing authority upon 
    request. The ``NPDES Guidance Document'' can be used as a reference 
    which contains technical information on BMPs and the elements of the 
    BMP program. The permittee shall develop and implement a BMP plan which 
    prevents, or minimizes the potential for, the release of pollutants 
    from ancillary activities, including material storage areas; plant site 
    runoff; in-plant transfer, process and material handling areas; loading 
    and unloading operations, and sludge and waste disposal areas, to the 
    waters of the United States through plant site runoff; spillage or 
    leaks; sludge or waste disposal; or drainage from raw material storage. 
    The term pollutants refers to any substance listed as toxic under 
    Section 307(a)(1) of the Clean Water Act, oil, as defined in Section 
    311(a)(1) of the Act, and substance listed as hazardous under Section 
    311 of the Act. Copies of the ``NPDES Guidance Document'' may be 
    obtained by submitting written requests to: Director, Water Management 
    Division, U.S. EPA Region IV, 345 Courtland St. N.E., Atlanta, Georgia 
    30365.
    2. Pollution Prevention Plan
        New permittees with long term treatment systems expected to 
    discharge one (1) year or more shall develop a Pollution Prevention 
    Plan for the site and submit it with the NOI. It shall contain the 
    following information:
        (a) A Narrative of What Caused the Groundwater Contamination.
        (b) Methods currently being deployed at the site to prevent 
    groundwater contamination from reoccurring.
        (c) Other alternative treatment options which were considered in 
    reducing the groundwater contamination.
        (d) Explanation of why long term treatment of discharge to Surface 
    Waters of the United States was chosen as opposed to:
        (1) Reduction-Monitor Phase I--Using a combination of techniques to 
    significantly reduce groundwater contamination that could be achieved 
    in three (3) months or less, with the objective of reaching a monitor-
    only status.
        (2) Reduction-Monitor Phase II--Using a combination of techniques 
    to significantly reduce groundwater contamination that could be 
    achieved in six (6) months or less, with the objective of reaching a 
    monitor-only status.
        In an effort to promote pollution prevention, the Permit Issuing 
    Authority may issue permits which include or require pollution 
    prevention activities.
    
    Part V
    
    Whole Effluent Toxicity Testing Program, Acute Freshwater Language
    
        As required by Part I of the permit, within 30-days after 
    commencement of discharge, permittees discharging to fresh waters, 
    which are surface waters in which the chloride concentration at the 
    surface is less than 1500 milligrams per liter, shall initiate the 
    series of tests described below to evaluate whole effluent toxicity of 
    the discharge from the outfall. If more than one (1) outfall exists, 
    separate tests will be performed on each outfall. All test species, 
    procedures and quality assurance criteria used shall be in accordance 
    with Methods for Measuring the Acute Toxicity of Effluents to 
    Freshwater and Marine Organisms, EPA/600/4-90/027F, or the most current 
    edition. The dilution/control water used will be moderately hard water 
    as described in EPA/600/4-90/027F, Section 7, or the most current 
    edition. A standard reference toxicant quality assurance test shall be 
    conducted concurrently with each species used in the toxicity tests and 
    the results submitted with the discharge monitoring report (DMR). 
    Alternatively, if monthly QA/QC reference toxicant tests are conducted, 
    these results must be submitted with the DMR.
        1. a. The permittee shall conduct 96-hour acute static-renewal 
    multi-concentration toxicity tests using the daphnid (Ceriodaphnia 
    dubia) and the fathead minnow (Pimephales promelas). All tests shall be 
    conducted on one grab sample of 100% final effluent. All tests shall be 
    conducted on a control (0%) and the following dilution concentrations 
    at a minimum: 100.0%, 50.0%, 25.0%, 12.5%, and 6.25%.
        b. If control mortality exceeds 10% for either species in any test, 
    the test(s) for that species (including the control) shall be repeated. 
    A test will be considered valid only if control mortality does not 
    exceed 10% for either species.
        2. The toxicity tests specified above shall be conducted once every 
    month until three (3) valid monthly tests have been completed, and once 
    every year thereafter for the duration of the permit, unless notified 
    otherwise by the permit issuing authority. These tests are referred to 
    as ``routine'' tests.
        3. a. If unacceptable acute toxicity (an LC50 of 100% or less 
    occurs in either test species in any of the above-described tests 
    within the specified time) is found in a ``routine'' test, the 
    permittee shall conduct two additional acute toxicity tests in the same 
    manner as the ``routine'' test on the specie(s) indicating unacceptable 
    acute toxicity. For each additional test, the sample collection 
    requirements and test acceptability criteria specified in Section 1 
    above must be met for the test to be considered valid. The first test 
    shall begin within two weeks of the end of the ``routine'' tests, and 
    shall be conducted weekly thereafter until two additional, valid tests 
    are completed. The additional tests will be used to determine if the 
    toxicity found in the ``routine'' test is still present.
        b. Results from additional tests, required due to unacceptable 
    acute toxicity in the ``routine'' test(s), must be reported on the 
    Discharge Monitoring Report (DMR) Form for the month in which the test 
    was begun. Such test results must be submitted within 45 days of 
    completion of the second additional, valid test.
    
    Part V
    
    Whole Effluent Toxicity Testing Program, Acute Saltwater Language
    
        As required by Part I of this permit, within 30-days after 
    commencement of discharge, permittees discharging to marine waters, 
    which are surface waters in which the chloride concentration at the 
    surface is greater than or equal to 1500 milligrams per liter, shall 
    initiate the series of tests described below to evaluate whole effluent 
    toxicity of the discharge from the outfall. If more than one (1) 
    outfall exists, separate tests will be performed on each outfall. All 
    test species, procedures and quality assurance criteria used shall be 
    in accordance with Methods for Measuring the Acute Toxicity of 
    Effluents to Freshwater and Marine Organisms, EPA/600/4-90/027F, or the 
    most current edition. The dilution/control water and effluent used will 
    be adjusted to a salinity of 20 parts per thousand using artificial sea 
    salts as described in EPA/600/4-90/027F, Section 7 (or the most current 
    edition). A standard reference toxicant quality assurance test shall be 
    conducted concurrently with each species used in the toxicity tests and 
    the results submitted with the discharge monitoring report (DMR). 
    Alternatively, if monthly QA/QC reference toxicant tests are conducted, 
    these results must be submitted with the DMR.
        1. a. The permittee shall conduct 96-hour acute static-renewal 
    multi-concentration toxicity tests using the mysid shrimp (Mysidopsis 
    bahia) and the inland silverside (Menidia beryllina). All tests shall 
    be conducted on one grab sample of 100% final effluent. All tests shall 
    be conducted on a control (0%) and the following dilution 
    concentrations at a minimum: 100.0%, 50.0%, 25.0%, 12.5%, and 6.25%.
        b. If control mortality exceeds 10% for either species in any test, 
    the test(s) for that species (including the control) shall be repeated. 
    A test will be considered valid only if control mortality does not 
    exceed 10% for either species.
        2. The toxicity tests specified above shall be conducted once every 
    month until three (3) valid monthly tests have been completed, and once 
    every year thereafter for the duration of the permit, unless notified 
    otherwise by the permit issuing authority. These tests are referred to 
    as ``routine'' tests.
        3. a. If unacceptable acute toxicity (an LC50 of 100% or less 
    occurs in either test species in any of the above- described tests 
    within the specified time) is found in a ``routine'' test, the 
    permittee shall conduct two additional acute toxicity tests in the same 
    manner as the ``routine'' test on the specie(s) indicating unacceptable 
    toxicity. For each additional test, the sample collection requirements 
    and test acceptability criteria specified in Section 1 above must be 
    met for the test to be considered valid. The first test shall begin 
    within two weeks of the end of the ``routine'' tests, and shall be 
    conducted weekly thereafter until two additional, valid tests are 
    completed. The additional tests will be used to determine if the 
    toxicity found in the ``routine'' test is still present.
        b. Results from additional tests, required due to unacceptable 
    acute toxicity in the ``routine'' test(s), must be reported on the 
    Discharge Monitoring Report (DMR) Form for the month in which the test 
    was begun. Such test results must be submitted within 45 days of 
    completion of the second additional, valid test.
