    Approval and Promulgation of State Implementation Plans and 
    Redesignation of the South Coast Air Basin in California to Attainment 
    for Nitrogen Dioxide
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Direct final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: EPA is taking direct final action on attainment and 
    maintenance plans and a request submitted by the California Air 
    Resources Board (CARB) to redesignate the South Coast Air Basin (South 
    Coast) from nonattainment to attainment for the National Ambient Air 
    Quality Standards (NAAQS) for Nitrogen Dioxide (NO2). Under 
    the Clean Air Act (CAA), designations can be revised if sufficient data 
    are available to warrant such revisions. In this action, EPA is 
    approving the attainment and maintenance plans as revisions to the 
    California State Implementation Plan (SIP), and EPA is also approving 
    the State's request to redesignate the South Coast to attainment 
    because the plans and request meet the requirements set forth in the 
    CAA.
        EPA is publishing this rule without prior proposal because the 
    Agency views this as a noncontroversial amendment and anticipates no 
    adverse comments. However, in the proposed rules section of this 
    Federal Register publication, EPA is publishing a separate document 
    that will serve as the proposal to approve the SIP revision and grant 
    the redesignation request should relevant adverse comments be filed.
    
    DATES: This rule is effective September 22, 1998 unless the Agency 
    receives relevant adverse comments to the rulemaking by August 24, 
    1998. If adverse comment is received, EPA will publish a timely 
    withdrawal of the direct final rule in the Federal Register and inform 
    the public that the rule will not take effect.
    
    ADDRESSES: Comments should be addressed to the EPA contact below. The 
    rulemaking docket for this notice may be inspected and copied at the 
    following location during normal business hours. A reasonable fee may 
    be charged for copying parts of the docket.

    SUPPLEMENTARY INFORMATION:
    
    I. Clean Air Act Requirements
    
        Under section 109 of the CAA, EPA established primary and secondary 
    NAAQS for NO2 in 1971, and slightly revised the NAAQS in 
    1985.1 The level of both the primary and secondary NAAQS is 
    0.053 parts per million (ppm), or 100 micrograms per cubic meter, 
    annual arithmetic mean concentration. The standards are attained when 
    the annual arithmetic mean concentration in a calendar year is less 
    than or equal to 0.053 ppm, based upon hourly data that are at least 
    75% complete.2
    ---------------------------------------------------------------------------
    
        \1\ See 34 FR 8186, April 30, 1971, and 50 FR 25544, June 19, 
    1985, codified at 40 CFR 50.11. Nitrogen dioxide is a light brown 
    gas that can irritate the lungs and lower resistance to respiratory 
    infections such as influenza. The principal sources of nitrogen 
    oxides are high-temperature combustion processes, such as those 
    occurring in motor vehicles and power plants.
        \2\ EPA's monitoring requirements for NO2 are 
    codified at 40 CFR 50, Appendix F. In determining whether an 
    NO2 nonattainment area has attained the NAAQS, EPA 
    considers not only the most recent four quarters of monitored 
    ambient air quality data available, but also the previous four 
    quarters of monitoring data ``to assure that the current indication 
    of attainment was not the result of a single year's data reflecting 
    unrepresentative meteorological conditions.'' 43 FR 8962 (March 3, 
    1978).
    ---------------------------------------------------------------------------
    
        The Federal CAA was substantially amended in 1990 to establish new 
    planning requirements and attainment deadlines for the NAAQS. Under 
    section 107(d)(1)(C) of the amended Act, an area designated 
    nonattainment prior to enactment of the 1990 amendments (as was the 
    South Coast Air Basin) was designated nonattainment by operation of 
    law.3 Under section 191 of the Act, an NO2 area 
    designated nonattainment under section 107(d) was required to submit to 
    EPA within 18 months of the
    
    [[Page 39748]]
    
    designation a plan meeting the requirements of Part D of the Act. Under 
    section 192 of the Act, such plans were required to provide for 
    attainment of the NAAQS as expeditiously as practicable but no later 
    than 5 years from the date of designation. In addition, Section 172 of 
    the Act contains general requirements applicable to SIPs for 
    nonattainment areas.
    ---------------------------------------------------------------------------
    
        \3\ By the date of enactment of the 1990 amendments, the South 
    Coast was the only remaining area in the country designated as 
    nonattainment for NO2. For a description of the 
    boundaries of the South Coast Air Basin (also known as the Los 
    Angeles-South Coast Air Basin Area), see 40 CFR 81.305. The 
    nonattainment area includes all of Orange County and the non-desert 
    portions of Los Angeles, San Bernardino, and Riverside Counties.
    ---------------------------------------------------------------------------
    
        The most fundamental of the CAA provisions for NO2 
    nonattainment areas is the requirement that the State submit a SIP 
    demonstrating attainment of the NAAQS as expeditiously as practicable 
    but no later than the applicable CAA deadline. Such a demonstration 
    must provide enforceable measures to achieve emission reductions each 
    year leading to emissions at or below the level predicted to result in 
    attainment of the NAAQS throughout the nonattainment area.
        EPA has issued a ``General Preamble'' describing the Agency's 
    preliminary views on how EPA intends to act on SIPs submitted under 
    Title I of the Act. See generally 57 FR 13498 (April 16, 1992) and 57 
    FR 18070 (April 28, 1992). The reader should refer to the General 
    Preamble for a more detailed discussion of EPA's preliminary 
    interpretations of Title I requirements. In this rulemaking action, EPA 
    is applying these policies to the South Coast NO2 SIP 
    submittal, taking into consideration the specific factual issues 
    presented.
        Section 107(d)(3)(E) of the 1990 CAA Amendments provides five 
    specific requirements that an area must meet in order to be 
    redesignated from nonattainment to attainment.
        1. The area must have attained the applicable NAAQS;
        2. The area must have a fully approved SIP under section 110 of 
    CAA;
        3. The air quality improvement must be permanent and enforceable;
        4. The area must have a fully approved maintenance plan pursuant to 
    section 175A of the CAA; and
        5. The area must meet all applicable requirements under section 110 
    and Part D of the CAA.
    
    II. Description of SIP Submittal
    
        On February 5, 1997, CARB submitted as a revision to the California 
    SIP the 1997 Air Quality Management Plan (AQMP) for the South Coast Air 
    Basin (SCAB), Antelope Valley, and Coachella Valley, adopted by the 
    South Coast Air Quality Management District (SCAQMD) on November 15, 
    1996. This submittal, which included a revised South Coast 
    NO2 attainment plan and a maintenance plan, was found to be 
    complete on April 1, 1997, with respect to portions of the AQMP 
    relating to NO2 SIP requirements.4 The 1997 
    NO2 plan supersedes all prior submittals.5 This 
    submittal was supplemented by documentation providing information to 
    substantiate the redesignation request. The additional documentation 
    was submitted on March 4, 1998, and determined to be complete on May 5, 
    1998.
    ---------------------------------------------------------------------------
    
        \4\ EPA adopted the completeness criteria on February 16, 1990 
    (55 FR 5830) and, pursuant to section 110(k)(1)(A) of the CAA, 
    revised the criteria on August 26, 1991 (56 FR 42216).
        \5\ The initial NO2 SIP for the South Coast was 
    adopted on April 3, 1992, and submitted on May 15,1992. EPA did not 
    act on this plan since significant revisions to the emissions 
    inventory and control strategy were already in progress. The plan 
    was revised as part of a 1994 AQMP update, which was adopted on 
    September 9, 1994, and submitted on November 15, 1994. A revision to 
    the 1994 AQMP was adopted on April 12, 1996, and submitted on July 
    10, 1996. On January 8, 1997, EPA approved the portions of the 1994 
    AQMP (as revised in 1996) relating to ozone, including the 
    commitments to adopt additional measures to reduce emissions of 
    volatile organic compounds (VOC) and oxides of nitrogen 
    (NOX).
    ---------------------------------------------------------------------------
    
        This 1997 NO2 plan provides, among other things, a 
    demonstration of attainment of the NO2 NAAQS, updated 
    historic and projected emission inventories, amended contingency 
    measures, and corrected air quality modeling analyses using the revised 
    inventories.
    
    III. EPA Review of the SIP Submittal
    
    A. Attainment Plan
    
    1. Procedural Requirements
        Both the SCAQMD and CARB have satisfied applicable statutory and 
    regulatory requirements for reasonable public notice and hearing prior 
    to adoption of the plan. The SCAQMD conducted numerous public workshops 
    and public hearings prior to the adoption hearing on November 15, 1996, 
    at which the 1997 AQMP was adopted by the Governing Board of the SCAQMD 
    (Resolution No. 96-23). On January 23, 1997, the Governing Board of 
    CARB adopted the plan (Resolution No. 97-1). The plan was submitted to 
    EPA by Michael P. Kenny, Executive Officer of CARB, on February 5, 
    1997. The SIP submittal includes proof of publication for notices of 
    SCAQMD and CARB public hearings, as evidence that all hearings were 
    properly noticed.
        Supplemental information from the SCAQMD and a formal redesignation 
    request by the State (Executive Order G-125-231) were formally 
    submitted to EPA by Michael P. Kenny on March 4, 1998. The supplemental 
    information was submitted pursuant to the resolutions by the Governing 
    Boards of SCAQMD and CARB in adopting the 1997 AQMP.
        Therefore, EPA proposes to approve the NO2 plan as 
    meeting the procedural requirements of section 110(a)(1) of the CAA.
    2. Emissions Inventory
        Appendix III of the 1997 AQMP includes planning emission 
    inventories for NOX for the historical years 1987, 1990, and 
    1993. The plan also includes future year inventories through the year 
    2010, both with and without planned controls. The inventories detail 
    emissions from all stationary and mobile source categories.
        EPA emissions inventory guidance allows approval of California's 
    motor vehicle emissions factors in place of the corresponding federal 
    emissions factors.6 The motor vehicle emissions factors used 
    in the plan were generated by the CARB EMFAC7G and BURDEN7G program. 
    The gridded inventory for motor vehicles was then produced using an 
    updated Caltrans Direct Travel Impact Model (DTIM2) to combine EMFAC7G 
    data with transportation modeling performed by the Southern California 
    Association of Governments (SCAG). SCAG also provided the socioeconomic 
    data used in the plan.
    ---------------------------------------------------------------------------
    
        \6\ EPA's general guidance for preparing emission inventories is 
    referenced in Appendix B to the General Preamble (57 FR 18070, April 
    28, 1992).
    ---------------------------------------------------------------------------
    
        The baseline emissions inventory meets CAA requirements in that it 
    is comprehensive, accurate, and current. EPA approves the emissions 
    inventory portion of the plan as meeting the requirements of section 
    172(c)(3) of the CAA.
    3. Attainment Demonstration
        The 1990 CAA Amendments required the South Coast to demonstrate 
    attainment no later than November 15, 1995.7 The 
    demonstration must show that emissions will be (or have been) reduced 
    to levels at which the NO2 NAAQS will not be exceeded. This 
    means that the SIP must show that the annual arithmetic mean of 
    NO2 ambient concentrations will not exceed 0.053 ppm at any 
    location within the nonattainment area.
    ---------------------------------------------------------------------------
    
        \7\ The South Coast area was designated nonattainment for 
    NO2 before the date of enactment of the 1990 amendments, 
    but the area lacked a fully approved SIP for NO2. 
    Consequently, the area was subject to the provisions of CAA section 
    191(b), which required submittal of an attainment plan within 18 
    months of enactment of the 1990 amendments (or May 15, 1992), and 
    section 192(b), which required attainment within 5 years after the 
    date of enactment of the amendments (or November 15, 1995).
    ---------------------------------------------------------------------------
    
        The peak annual arithmetic mean concentrations for all monitoring 
    stations in the South Coast have been
    
    [[Page 39749]]
    
    0.0507 ppm in 1992, 0.0499 ppm in 1993, 0.0499 ppm in 1994, 0.0464 ppm 
    in 1995, 0.0461 ppm in 1996, and 0.043 ppm in 1997. Thus, the South 
    Coast has not exceeded the NO2 NAAQS since 1991 at any of 
    the 24 monitoring locations in the air basin.
        The South Coast monitoring network is reviewed annually by CARB and 
    EPA, and has been determined to be generally reflective of air quality 
    throughout the air basin. Periodic CARB and EPA reviews also confirm 
    that the data collected has met applicable Federal standards for 
    quality assurance.
        As discussed below in the description of the maintenance plan 
    provisions, the SCAQMD has also performed modeling for key locations in 
    the air basin to show that future NO2 concentrations will 
    remain below the NAAQS, taking credit for only those controls that were 
    already fully adopted in regulatory form by September 30, 1996. This 
    modeling shows a continuing decline in NO2 concentrations 
    throughout the air basin.
        EPA approves the attainment demonstration portion of the plan as 
    meeting the requirements of sections 192(b) of the CAA, since it 
    demonstrates that the area attained the NAAQS before the applicable 
    deadline of November 15, 1995.
    4. Additional Attainment Plan Requirements
        Section 172(c)(1) requires that plans provide for the 
    implementation of all reasonably available control measures (RACMs) as 
    expeditiously as practicable, including the adoption of reasonably 
    available control technology (RACT). In numerous prior actions, EPA has 
    approved NOX RACT regulations for the SCAQMD. The SCAQMD's 
    extensive NOX regulations are generally recognized as among 
    the most stringent and comprehensive in the nation. Therefore, EPA 
    approves the NO2 plan with respect to the RACM requirement 
    of section 172(c)(1).
        Section 172(c)(2) of the CAA requires that nonattainment area plans 
    require reasonable further progress (RFP), which section 171(1) defines 
    as ``annual incremental reductions in emissions of the relevant air 
    pollutant as are required * * * for the purpose of ensuring attainment 
    * * * by the applicable date.'' The emissions inventory data included 
    in the 1997 AQMP and supplement show significant annual declines in 
    NOX emissions from 1990 through the present. These 
    reductions, derived from SCAQMD stationary and area source controls and 
    CARB mobile source controls, were sufficient to prevent violations of 
    the NO2 NAAQS after 1991, several years before the statutory 
    attainment deadline of 1995. Therefore, EPA approves the plan as 
    meeting the RFP requirements of section 172(c)(2).
        CAA sections 172(c)(4) and (5) require that nonattainment plans 
    quantify emissions from major new or modified stationary sources, and 
    include a permit program for these sources that meets the requirements 
    of section 173. The 1997 plan's emissions inventory includes 
    projections of emissions from new sources. EPA has previously approved 
    the South Coast's permit program (Regulation XIII) as meeting the 
    requirements of the CAA and EPA's New Source Review regulations. See 61 
    FR 64291 (December 4, 1996). Therefore, EPA approves the plan as 
    meeting the new source requirements of sections 172(c)(4) and (5) of 
    the CAA.
        CAA section 172(c)(9) requires that nonattainment plans include 
    contingency measures to take effect if the area fails to meet RFP or to 
    attain by the applicable deadline. Since the area attained the 
    NO2 NAAQS before its deadline, this requirement is no longer 
    germane. In Section III.B., below, EPA addresses the contingency 
    measure requirement for the NO2 maintenance plan.
    
    B. Maintenance Plan and Redesignation
    
    1. Attainment of the NAAQS
        The supplemental information submitted on March 4, 1998, includes 
    Attachment A, which presents a table displaying NO2 annual 
    arithmetic average values for all South Coast monitors for the period 
    1976 through 1996. This table indicates that the last year with an 
    NO2 violation was 1991, when the Pomona site had a 0.0550 
    ppm value, slightly above the 0.053 ppm NAAQS. During the most recent 
    year shown in the submittal (1996), only 5 of 23 stations had values 
    above 0.0400 ppm. The peak value, at the East San Fernando Valley site, 
    was 0.0461 ppm, approximately 15% below the NAAQS. Data for 1997 
    entered in EPA's Aerometric Information Retrieval System (AIRS) show 
    that air quality has improved further, with a peak concentration of 
    0.043 ppm for the year, almost 20% below the NAAQS. The docket for this 
    rulemaking includes the SCAQMD data summary and the AIRs data for 1997.
        The South Coast more than meets applicable EPA redesignation 
    requirements for NO2, since the area has reached and then 
    sustained attainment by having had no exceedances of the NAAQS for 6 
    complete, consecutive calendar years.
    2. Approval of the Applicable Implementation Plan
        As set forth in Section III.A. above, this criterion for 
    redesignation is satisfied because the NO2 plan for the 
    South Coast is fully approved.
    3. Improvement in Air Quality Due to Permanent and Enforceable Measures
        Redesignation to attainment requires that the improvements in air 
    quality must be shown to have occurred because of enforceable controls, 
    rather than as a result of temporary economic conditions or favorable 
    meteorology. The South Coast NOX emissions inventory shows 
    increases in activity levels for most of the significant categories 
    (including motor vehicle use) during the years with no NO2 
    violations. This shows that the reductions in NOX emissions 
    are not due to an economic recession, but are associated with the 
    impact of permanent and enforceable CARB controls on mobile source 
    emissions and SCAQMD regulations on stationary and area sources. Fleet 
    turnover and progressively more stringent CARB requirements for future 
    year vehicles and engines are expected to sustain this continuing 
    decline in areawide NOX emissions, despite projected growth. 
    Therefore, this redesignation criterion is met.
    4. Fully Approved Maintenance Plan
        Section 175A of the CAA requires States to submit maintenance plans 
    for areas eligible for redesignation to attainment. The maintenance 
    plan must include four elements: an emissions inventory, a 
    demonstration that the NAAQS will be maintained for at least 10 years 
    from the date of redesignation, contingency measures, and a commitment 
    to submit a revised maintenance SIP eight years after the area is 
    redesignated to attainment.
        a. Emissions inventory. As discussed above, the 1997 plan includes 
    baseline inventory data for 1987, 1990, and 1993, and thus covers the 
    period associated with attaining the NAAQS, as required for maintenance 
    plans.8
    ---------------------------------------------------------------------------
    
        \8\ See, for example, the General Preamble at 57 FR 13563 (April 
    16, 1992).
    ---------------------------------------------------------------------------
    
        As discussed above in Section II, the emission inventories meet 
    applicable inventory requirements and EPA also approves the inventory 
    portions of the plan under section 175A.
        b. Demonstration of maintenance. For the maintenance demonstration, 
    the plan must either demonstrate that the future year inventory will 
    not exceed the inventory that existed at the time of the request for 
    redesignation, or include a modeling analysis showing that the
    
    [[Page 39750]]
    
    future mix of emissions, assuming existing SIP controls, will not cause 
    violations of the NAAQS.
        The 1997 NO2 plan projects baseline emissions to 2010. 
    The table below, labeled ``South Coast NOX Emissions,'' 
    shows the decline in NOX emissions from 1993 through 2010, 
    assuming no new control measures. Projections are made for Pomona 
    because that area has generally experienced the highest measured annual 
    NO2 concentrations in the air basin.
    
    South Coast NOX Emissions in tons per winter day for the South Coast Air
                            Basin and the Pomona Area                       
                       [1997 AQMP, Appendix V, Table 1-1]                   
    ------------------------------------------------------------------------
                            Year                            SCAB     Pomona 
    ------------------------------------------------------------------------
    1993................................................     1284       36.7
    2000................................................      960       28.0
    2010................................................      759       21.9
    ------------------------------------------------------------------------
    
        The SCAQMD also employed a linear rollback modeling approach, 
    assuming that ambient concentrations are directly proportional to 
    emissions in adjacent areas. The analysis used NO2/
    NOX ratios averaged over the period 1992-4 for each site. 
    The results of this modeling analysis show annual average 
    NO2 concentrations for a 2010 baseline scenario, assuming 
    reductions only from existing regulations. At the peak site (Pomona), 
    the projected concentration is approximately 0.030 ppm, more than 45% 
    below the NAAQS.
        c. Contingency measures. Maintenance plans for attainment areas 
    must include contingency provisions, or extra measures beyond those 
    needed for attainment, to offset any unexpected increase in emissions 
    and ensure that the standard is maintained (175(A)(d)). Typically, 
    contingency measures are held in reserve and implemented only if an 
    area violates the standard in the future. However, the California SIP 
    already includes fully adopted regulations which will generate (as 
    shown above) reductions in NOX emissions in future years 
    that will provide an ample margin of safety to ensure maintenance of 
    the standard and to provide adequate additional reductions to cover the 
    contingency requirements. These regulations include the California 
    motor vehicle and fuels program, California and Federal requirements 
    for nonroad vehicles and engines, and SCAQMD ``declining cap'' 
    regulations for stationary sources: Rule 1135--Emissions of Oxides of 
    Nitrogen from Electric Power Generating Systems, and Regulation XX--
    Regional Clean Air Incentives Market (RECLAIM). In addition, in acting 
    on the 1994 ozone SIP for the South Coast, EPA has approved and made 
    federally enforceable commitments by SCAQMD and CARB to adopt further 
    stationary and mobile source controls on NOX emissions. 
    These controls are scheduled to achieve more than 150 tons per day in 
    reductions of NOX emissions in the South Coast by the year 
    2010.9 Therefore, EPA approves the contingency measure 
    provisions under section 175A, based on the regulations and enforceable 
    commitments that have already been incorporated into the SIP.

        \9\ See 62 FR 1150-1187 (January 8, 1997), EPA's final approval 
    of the California ozone SIPs, which lists the federally approved 
    CARB and SCAQMD measures, along with both the VOC and NOX 
    reductions associated with the measures for each ozone milestone 
    year through 2010 (1999, 2002, 2005, 2008, and 2010).

        d. Subsequent maintenance plan revisions. In accordance with 
    section 175A(b) of the CAA, the State has agreed to submit a revised 
    maintenance SIP eight years after the area is redesignated to 
    attainment. Such revised SIP will provide for maintenance for an 
    additional ten years. In California, nonattainment areas must update 
    their plans every 3 years to meet State law requirements, so even more 
    frequent updates to the maintenance plan are expected.
        e. Approval of the maintenance plan and redesignation request. EPA 
    approves under section 110(k)(3) of the CAA the South Coast 
    NO2 maintenance plan as meeting the requirements of sections 
    110 and 175A of the CAA. Since all of the CAA section 107(d)(3)(E) 
    redesignation requirements have been met, EPA grants the request of the 
    State to redesignate the South Coast Air Basin to attainment for the 
    NO2 NAAQS.
    
    IV. EPA Final Action
    
        Under CAA section 110(k)(3), EPA approves the South Coast 
    NO2 plan portion of the 1997 AQMP as meeting the 
    requirements of CAA sections 110, 172, and 192 with respect to the 
    nonattainment plan requirements, and the requirements of CAA sections 
    110 and 175A with respect to the maintenance plan requirements. EPA is 
    redesignating the South Coast to attainment for NO2 under 
    CAA section 107.
        EPA is taking these actions without prior proposal because the 
    Agency views this as noncontroversial and anticipates no adverse 
    comments. However, if EPA receives relevant adverse comments by August 
    24, 1998, then EPA will publish a document that withdraws the rule and 
    informs the public that the rule will not take effect. EPA will then 
    address those comments in a final action based upon the proposed rule, 
    which appears as a separate document in the proposed rules section of 
    this Federal Register publication. EPA will not institute a second 
    comment period. Any parties interested in commenting should do so at 
    this time. If no such comments are received, the public is advised that 
    this rule will be effective on September 22, 1998, and no further 
    action will be taken on the proposed rule.
        Nothing in this action should be construed as permitting or 
    allowing or establishing a precedent for any future implementation 
    plan. Each request for revision to the state implementation plan shall 
    be considered separately in light of specific technical, economic, and 
    environmental factors and in relation to relevant statutory and 
    regulatory requirements.
    
    V. Administrative Requirements
    
    A. Executive Order 12866
    
        The Office of Management and Budget (OMB) has exempted this 
    regulatory action from E.O. 12866 review.
    
    B. Regulatory Flexibility Act
    
        Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
    must prepare a regulatory flexibility analysis assessing the impact of 
    any proposed or final rule on small entities. 5 U.S.C. 603 and 604. 
    Alternatively, EPA may certify that the rule will not have a 
    significant impact on a substantial number of small entities. Small 
    entities include small business, small not-for-profit enterprises and 
    government entities with jurisdiction over populations of less than 
    50,000.
        SIP approvals under sections 110 and subchapter I, part D of the 
    CAA, do not create any new requirements, but simply approve 
    requirements that the State is already imposing. Therefore, because the 
    Federal SIP approval does not impose any new requirements, the 
    Administrator certifies that it does not have a significant impact on 
    any small entities affected. Moreover, due to the nature of the 
    Federal-State relationship under the CAA, preparation of a regulatory 
    flexibility analysis would constitute Federal inquiry into the economic 
    reasonableness of state action. The CAA forbids EPA to base its actions 
    concerning SIP's on such grounds. Union Electric Co. v. U.S.E.P.A., 427 
    U.S. 246, 256-66 (S.Ct. 1976); 42 U.S.C. 7410(a)(2).
    
    C. Unfunded Mandates
    
        Under sections 202 of the Unfunded Mandates Reform Act of 1995
    
    [[Page 39751]]
    
    (``Unfunded Mandates Act'') signed into law on March 22, 1995, EPA must 
    prepare a budgetary impact statement to accompany any proposed or final 
    rule that includes a Federal mandate that may result in estimated costs 
    to State, local, or tribal governments in the aggregate; or to the 
    private sector, of $100 million or more. Under Section 205, EPA must 
    select the most cost-effective and least burdensome alternative that 
    achieves the objectives of the rule and is consistent with statutory 
    requirements. Section 203 requires EPA to establish a plan for 
    informing and advising any small governments that may be significantly 
    or uniquely impacted by the rule.
        EPA has also determined that this final action does not include a 
    mandate that may result in estimated costs of $100 million or more to 
    State, local, or tribal governments in the aggregate or to the private 
    sector. This Federal action approves pre-existing requirements under 
    State or local law, and imposes no new Federal requirements. 
    Accordingly, no additional costs to State, local, or tribal 
    governments, or to the private sector, result from this action.
    
    D. Submission to Congress and the General Accounting Office
    
        The Congressional Review Act, 5 U.S.C. Sec. 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 to 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. This rule is 
    not a ``major'' rule as defined by 5 U.S.C. Sec. 804(2).
    
    E. Petitions for Judicial Review
    
        Under section 307(b)(1) of the Clean Air Act, petitions for 
    judicial review of this action must be filed in the United States Court 
    of Appeals for the appropriate circuit by September 22, 1998. Filing a 
    petition for reconsideration by the Administrator of this final rule 
    does not affect the finality of this rule for the purposes of judicial 
    review nor does it extend the time within which a petition for judicial 
    review may be filed, and shall not postpone the effectiveness of such 
    rule or action. This action may not be challenged later in proceedings 
    to enforce its requirements. (See section 307(b)(2).)
    
    F. Executive Order 13045
    
        The final rule is not subject to E.O. 13045, entitled Protection of 
    Children from Environmental Health Risks and Safety Risks, because it 
    is not an ``economically significant'' action under E.O. 12866.
