    Approval and Promulgation of Implementation Plans and Designation 
    of Areas for Air Quality Planning Purposes; Commonwealth of Kentucky
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Direct final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: On November 13, 1992, the Commonwealth of Kentucky through the 
    Natural Resources and Environmental Protection Cabinet (Cabinet), 
    submitted a maintenance plan and a request to redesignate the 
    Lexington, Owensboro, Paducah, and Edmonson County areas from 
    nonattainment to attainment for ozone (O3). Under the Clean Air 
    Act (CAA), designations can be changed if sufficient data are available 
    to warrant such changes and the redesignation request satisfies the 
    criteria set forth in the CAA. In this action, EPA is approving the 
    redesignation to attainment of the Lexington area (Fayette and Scott 
    counties) and the associated maintenance plan because it meets the 
    maintenance plan and redesignation requirements. EPA has approved the 
    requests to redesignate to attainment and maintenance plans for the 
    Owensboro, Edmonson County and Paducah areas. In this action, EPA is 
    also approving the 1990 base year inventory for the Lexington marginal 
    O3 nonattainment area.
    
    DATES: This final rule is effective November 13, 1995 unless adverse or 
    critical comments are received by October 11, 1995. If the effective 
    date is delayed, timely notice will be published in the Federal 
    Register.
    
    ADDRESSES: Written comments on this action should be addressed to Scott 
    Southwick, at the EPA Regional Office listed below. Copies of the 
    documents relative to this action are available for public inspection 
    during normal business hours at the following locations. The interested

    SUPPLEMENTARY INFORMATION: On November 15, 1990, the Clean Air Act 
    Amendments of 1990 (CAAA) were enacted. (Pub. L. 101-549, 104 Stat. 
    2399, codified at 42 U.S.C. 7401-7671q). Under section 107(d)(1), in 
    conjunction with the Governor of Kentucky, EPA designated the Lexington 
    area as nonattainment because the area violated the O3 standard 
    during the period from 1987 through 1989 (See 56 FR 56694 (Nov. 6, 
    1991) and 57 FR 56762 (Nov. 30, 1992), codified at 40 CFR 81.318).
        The Lexington marginal O3 nonattainment area (nonattainment 
    area) more recently has ambient monitoring data that show no violations 
    of the O3 National Ambient Air Quality Standards (NAAQS), during 
    the period from 1989 through 1991. In addition, there have been no 
    violations reported for the 1992, 1993, or 1994 O3 seasons. 
    Therefore, in an effort to comply with the amended CAA and to ensure 
    continued attainment of the NAAQS, on November 13, 1992, the Cabinet 
    submitted for parallel processing an O3 maintenance SIP for the 
    nonattainment area and requested redesignation of the nonattainment 
    area to attainment with respect to the O3 NAAQS and EPA found the 
    request complete. On November 24, 1992, the Cabinet submitted the 
    Marginal Ozone Nonattainment Areas Projection Inventory 1990-2004 as an 
    amendment to the SIP. On January 15, 1993, July 16, 1993, February 28, 
    1994, August 29, 1994, and June 14, 1995, the Cabinet submitted 
    revisions addressing public and/or EPA comments on the 
    
    [[Page 47090]]
    redesignation request, maintenance plan, and projection inventory.
        On May 7, 1993, Region 4 determined that the information received 
    from the Cabinet constituted a complete redesignation request under the 
    general completeness criteria of 40 CFR 51, appendix V, sections 2.1 
    and 2.2. However, for purposes of determining what requirements are 
    applicable for redesignation purposes, EPA believes it is necessary to 
    identify when the Cabinet first submitted a redesignation request that 
    meets the completeness criteria. EPA noted in a previous policy 
    memorandum that parallel processing requests for submittals under the 
    amended CAA, including redesignation submittals, would not be 
    determined complete. See ``State Implementation Plan (SIP) Actions 
    Submitted in Response to Clean Air Act (Act) Deadlines,'' Memorandum 
    from John Calcagni to Air Programs Division Directors, Regions I-X, 
    dated October 28, 1992 (Memorandum). The rationale for this conclusion 
    was that the parallel processing exception to the completeness criteria 
    (40 CFR Part 51, appendix V, section 2.3) was not intended to extend 
    statutory due dates for mandatory submittals. (See Memorandum at 3-4). 
    However, since requests for redesignation are not mandatory submittals 
    under the CAA, EPA believed it appropriate to change its policy with 
    respect to redesignation submittals to conform to the existing 
    completeness criteria (58 FR 38108 (July 15, 1993)). Therefore, EPA 
    believes, the parallel processing exception to the completeness 
    criteria may be applied to redesignation request submittals, at least 
    until such time as the EPA decides to revise that exception. The 
    Cabinet submitted a redesignation request and a maintenance plan on 
    November 13, 1992. When the maintenance plan became state effective on 
    June 14, 1995, the Commonwealth of Kentucky no longer needed parallel 
    processing for the redesignation request and maintenance plan.
        The Kentucky redesignation request for the nonattainment areas 
    meets the five requirements of section 107(d)(3)(E) for redesignation 
    to attainment. The following is a brief description of how the 
    Commonwealth of Kentucky has fulfilled each of these requirements. 
    Because the maintenance plan is a critical element of the redesignation 
    request, EPA will discuss its evaluation of the maintenance plan under 
    its analysis of the redesignation request.
    
    1. The Area Must Have Attained the O3 NAAQS
    
        The Cabinet's request is based on an analysis of quality assured 
    ambient air quality monitoring data which is relevant to the 
    maintenance plan and to the redesignation request. Ambient air quality 
    monitoring data for calendar year 1989 through calendar year 1991 show 
    an expected exceedance rate of less than 1.0 per year of the O3 
    NAAQS in the marginal nonattainment area. (See 40 CFR 50.9 and appendix 
    H.) In addition, there were no violations reported for the 1992, 1993, 
    and 1994 O3 seasons and there have been no violations to date in 
    1995. Because the nonattainment area has complete quality-assured data 
    showing no violations of the standard over the most recent consecutive 
    three calendar year period, the area has met the first statutory 
    criterion of attainment of the O3 NAAQS. The Commonwealth of 
    Kentucky has committed to continue monitoring the nonattainment area in 
    accordance with 40 CFR 58.
    
    2. The Area Has Met All Applicable Requirements Under Section 110, and 
    Part D of the Act
    
        On January 25, 1980, August 7, 1981, November 24, 1981, November 
    30, 1981, and March 30, 1983, EPA fully approved Kentucky's SIP as 
    meeting the requirements of section 110(a)(2) and part D of the 1977 
    CAA (45 FR 6092, 46 FR 40188, 46 FR 57486, 46 FR 58080, and 48 FR 
    13168). The approved control strategy did not result in attainment of 
    NAAQS for O3. Additionally, the amended CAA revised section 
    182(a)(2)(A), 110(a)(2) and, under part D, revised section 172 and 
    added new requirements for all nonattainment areas. Therefore, for 
    purposes of redesignation, to meet the requirement that the SIP contain 
    all applicable requirements under the CAA, EPA reviewed the Kentucky 
    SIP to ensure that it contains all measures due under the amended CAA 
    prior to or at the time the Commonwealth of Kentucky submitted its 
    redesignation request.
    
    A. Section 110 Requirements
    
        Although section 110 was amended by the CAA of 1990, the Kentucky 
    SIP for the marginal nonattainment area meets the requirements of 
    amended section 110(a)(2). A number of the requirements did not change 
    in substance and, therefore, EPA believes that the pre-amendment SIP 
    met these requirements.
    
    B. Part D Requirements
    
        Before the nonattainment area may be redesignated to attainment, it 
    must have fulfilled the applicable requirements of part D. Under part 
    D, an area's classification indicates the requirements to which it will 
    be subject. Subpart 1 of part D sets forth the basic nonattainment 
    requirements applicable to all nonattainment areas, classified as well 
    as nonclassifiable. Subpart 2 of part D establishes additional 
    requirements for O3 nonattainment areas classified under table 1 
    of section 181(a). The Lexington nonattainment area was classified as 
    marginal (See 56 FR 56694, codified at 40 CFR 81.318). The Commonwealth 
    of Kentucky submitted their request for redesignation of the marginal 
    nonattainment area prior to November 15, 1992. Therefore, in order to 
    be redesignated to attainment, the Commonwealth of Kentucky must meet 
    the applicable requirements of subpart 1 of part D, specifically 
    sections 172(c) and 176, but is not required to meet the applicable 
    requirements of subpart 2 of part D, which became due on or after 
    November 15, 1992.
    B1. Subpart 1 of Part D
        Under section 172(b), the section 172(c) requirements are 
    applicable as determined by the Administrator, but no later than three 
    years after an area has been designated to nonattainment. EPA has not 
    determined that these requirements were applicable to O3 
    nonattainment areas on or before November 13, 1992, the date that the 
    Commonwealth of Kentucky submitted a complete redesignation request for 
    the marginal nonattainment area. Therefore, the Commonwealth of 
    Kentucky was not required to meet these requirements for purposes of 
    redesignation. The Lexington area currently has a fully approvable New 
    Source Review (NSR) program which was last revised on June 23, 1994 (59 
    FR 32343). Upon redesignation of the area to attainment, the Prevention 
    of Significant Deterioration (PSD) provisions contained in part C of 
    title I are applicable. On January 25, 1978; September 1, 1989; 
    November 6, 1989; November 13, 1989; November 28, 1989; February 7, 
    1990; and June 23, 1994, the EPA approved revisions to the Commonwealth 
    of Kentucky's PSD program (43 FR 3360, 54 FR 36307, 54 FR 46613, 54 FR 
    47211, 54 FR 48887, 55 FR 4169 and 59 FR 32343).
        Section 176(c) of the CAA requires states to revise their SIPs to 
    establish criteria and procedures to ensure that Federal actions, 
    before they are taken, conform to the air quality planning goals in the 
    applicable state SIP. The requirement to determine conformity applies 
    to transportation plans, programs and projects developed, 
    
    [[Page 47091]]
    funded or approved under Title 23 U.S.C. or the Federal Transit Act 
    (``transportation conformity''), as well as to all other Federal 
    actions (``general conformity''). Section 176 further provides that the 
    conformity revisions to be submitted by states must be consistent with 
    Federal conformity regulations that the CAA required EPA to promulgate. 
    Congress provided for the state revisions to be submitted by November 
    15, 1992, one year after the date for promulgation of final EPA 
    conformity regulations which were due November 15, 1991. When that date 
    passed without such promulgation, EPA's General Preamble for the 
    Implementation of Title I informed states that its conformity 
    regulations would establish a submittal date [see 57 FR 13498, 13557 
    (April 16, 1992)].
        The EPA promulgated final transportation conformity regulations on 
    November 24, 1993, (58 FR 62188) and general conformity regulations on 
    November 30, 1993 (58 FR 63214). These conformity rules require that 
    states adopt both transportation and general conformity provisions in 
    the SIP for areas designated nonattainment or subject to a maintenance 
    plan approved under CAA section 175A. Pursuant to section 51.396 of the 
    transportation conformity rule and section 51.851 of the general 
    conformity rule, the Commonwealth of Kentucky is required to submit a 
    SIP revision containing transportation conformity criteria and 
    procedures consistent with those established in the Federal rule by 
    November 25, 1994. Similarly, Kentucky is required to submit a SIP 
    revision containing general conformity criteria and procedures 
    consistent with those established in the Federal rule by December 1, 
    1994. Because the Commonwealth requested redesignation of the Lexington 
    area prior to the deadline for these submittals, they are not 
    applicable requirements under section 107(d)(3)(E)(v) and, thus, do not 
    affect approval of this redesignation request.
        On February 24, 1994, the Commonwealth of Kentucky revised their 
    maintenance plan to commit to revise the SIP by November 25, 1994, to 
    be consistent with the final Federal regulations on conformity. In 
    addition, the Division for Air Quality and the Kentucky Transportation 
    Cabinet are cooperating in adopting regulations consistent with the 
    final conformity regulation.
    B2. Subpart 2 of Part D
        The CAA was amended on November 15, 1990, Pub. L. 101-549, 104 
    Stat. 2399, codified at 42 U.S.C. 7401-7671q. EPA was required to 
    classify O3 nonattainment areas according to the severity of their 
    problem. On November 6, 1991 (56 FR 56694), the Lexington area was 
    designated as marginal O3 nonattainment. Because this area is 
    marginal, the area must meet section 182(a) of the CAA. EPA has 
    analyzed the SIP and determined that it is consistent with the 
    requirements of amended section 182. Below is a summary of how the area 
    has meet the requirements of these sections.
    (1) Emissions Inventory
        The CAA required an inventory of all actual emissions from all 
    sources as described in section 172(c)(3) by November 15, 1992. On 
    November 13, 1992, the Cabinet submitted an emission inventory on the 
    Lexington area. This emission inventory is being approved in this 
    notice.
    (2) Reasonably Available Control Technology (RACT)
        The CAA also amended section 182(a)(2)(A), in which Congress 
    statutorily adopted the requirement that O3 nonattainment areas 
    fix their deficient Reasonably Available Control Technology (RACT) 
    rules for O3. Areas designated nonattainment before amendment of 
    the CAA and which retained that designation and were classified as 
    marginal or above as of enactment are required to meet the RACT Fix-ups 
    requirement. The Lexington area was not designated nonattainment prior 
    to 1990 and was classified as marginal O3 nonattainment pursuant 
    to the 1990 CAA. Therefore, this area is not subject to the RACT fix-up 
    requirement. However, Kentucky chose to apply RACT on all major sources 
    which commenced on or after the effective date of a particular RACT 
    rule. Kentucky submitted VOC RACT SIP revisions through the Cabinet to 
    EPA on February 12, 1992; October 20, 1992; February 17, 1993; and 
    March 4, 1993. Action was taken December 12, 1993, to approve the SIP 
    revision submitted on February 12, 1992. Action was taken June 23, 
    1994, to approve the SIP revisions submitted on October 20, 1992, 
    February 17, 1993, and March 4, 1993.
    (3) Emissions Statements
        The CAA required that the SIP be revised by November 15, 1992, to 
    require stationary sources of oxides of nitrogen (NOX) and VOCs to 
    provide the State with a statement showing actual emissions each year. 
    This request to redesignate was submitted prior to the November 15, 
    1992, emissions statement deadline. Therefore, the emissions statement 
    program is not a requirement for the Lexington area.
    (4) New Source Review (NSR)
        The CAA required all classified nonattainment areas to meet several 
    requirements regarding NSR, including provisions to ensure that 
    increased emissions of VOCs compounds will not result from any new or 
    major source modifications and a general offset rule. A SIP revision 
    incorporating these requirements was due November 15, 1992. This 
    request to redesignate was submitted prior to the November 15, 1992, 
    NSR deadline. Therefore, the NSR program is not a requirement for the 
    Lexington area.
    
    3. The Area Has a Fully Approved SIP Under Section 110(k) of the 
    CAA
    
        Based on the approval of provisions under the pre-amended CAA and 
    EPA's prior approval of SIP revisions under the amended CAA, EPA has 
    determined that Kentucky has a fully approved O3 SIP under section 
    110(k) for the marginal nonattainment areas, which also meets the 
    applicable requirements of section 110 and part D as discussed above.
    
    4. The Air Quality Improvement Must Be Permanent and Enforceable
    
        Several control measures have come into place since the 
    nonattainment area violated the O3 NAAQS. Of these control 
    measures, the reduction of fuel volatility from 11.4 psi to 8.6 psi, as 
    measured by the Reid Vapor Pressure (RVP), and fleet turnover produced 
    the most significant decreases in VOC emissions. The table below 
    summarizes total emissions for VOCs. The difference between 1988 and 
    1990 are actual permanent and enforceable emission reductions which are 
    responsible for the recent air quality improvement in the areas. The 
    VOC emissions in the base year are not artificially low due to local 
    economic downturn.

    5. The Area Must Have a Fully Approved Maintenance Plan Pursuant to 
    Section 175A of the CAA
    
        Section 175A of the CAA sets forth the elements of a maintenance 
    plan for areas seeking redesignation from nonattainment to attainment. 
    The plan 
    
    [[Page 47092]]
    must demonstrate continued attainment of the applicable NAAQS for at 
    least ten years after the Administrator approves a redesignation to 
    attainment. Eight years after the redesignation, the State must submit 
    a revised maintenance plan which demonstrates attainment for the ten 
    years following the initial ten-year period. To provide for the 
    possibility of future NAAQS violations, the maintenance plan must 
    contain contingency measures, with a schedule for implementation, 
    adequate to assure prompt correction of any air quality problems.
        In this notice, EPA is approving the Commonwealth of Kentucky's 
    maintenance plan for the Lexington marginal nonattainment area because 
    EPA finds that the Commonwealth of Kentucky's submittal meets the 
    requirements of section 175A.
    
    A. Emissions Inventory--Base Year Inventory
    
        On November 13, 1992, the Commonwealth of Kentucky submitted 
    comprehensive inventories of VOC, NOX, and CO emissions for the 
    Lexington marginal nonattainment area. The inventories included 
    biogenic, area, stationary, and mobile sources using 1990 as the base 
    year for calculations to demonstrate maintenance. The 1990 inventory is 
    considered representative of attainment conditions because the O3 
    NAAQS was not violated during 1990.
        The Commonwealth of Kentucky submittal contains the detailed 
    inventory data and summaries by county and source category. This 
    comprehensive base year emissions inventory was submitted in the SIP 
    Air Pollutant Inventory Management System (SAMS) format. Finally, this 
    inventory was prepared in accordance with EPA guidance. A summary of 
    the base year and projected maintenance year inventories for the 
    Lexington area is included in this notice for VOCs and NOX. The CO 
    and the biogenic VOC values are shown below and are a part of the 1990 
    base year emission inventory. This notice is approving the base year 
    inventory.

                     VOC and NOX Projected Emissions Changes                
    ------------------------------------------------------------------------
                                                              VOCs     NOX

    ------------------------------------------------------------------------
    
    
        Because there were increases in VOC and NOX emissions, 
    Kentucky was required to model to demonstrate maintenance of the 
    O3 standard despite emissions growth. The Empirical Kinetics 
    Modeling Approach (EKMA) was the model used. EKMA models Nonmethane 
    Organic Compounds (NMOC) and NMOC data were available in 1989. For this 
    reason, the model was run using meteorological data from June 23, June 
    26, and July 18, 1989. These days correspond to the highest ozone 
    monitor readings for which on-site NMOC were available. The EKMA 
    modeling projected O3 values of 0.106 parts per million (ppm) for 
    June 23, 1989, .116 ppm for July 26, 1989, and .064 ppm for July 18, 
    1995.
        The modeling indicated that the future mix of emissions produced 
    ozone levels below the federal O3 standard. Thus, the analysis 
    indicated that the Lexington area should continue to maintain the 
    standard throughout the maintenance period.
    
    C. Verification of Continued Attainment
    
        Continued attainment of the O3 NAAQS in the marginal 
    nonattainment areas depends, in part, on the Commonwealth of Kentucky's 
    efforts toward tracking indicators of continued attainment during the 
    maintenance period. The Commonwealth of Kentucky's contingency plan is 
    triggered by two indicators, the emissions inventory for interim years 
    exceeding the baseline emission inventory by more than 10% or an air 
    quality violation. As stated in the maintenance plan, the Cabinet will 
    be developing these emissions inventories every three years beginning 
    in 1996. These periodic inventories will help to verify continued 
    attainment.
    
    D. Contingency Plan
    
        The level of VOC and NOX emissions in the nonattainment area 
    will largely determine its ability to stay in compliance with the 
    O3 NAAQS in the future. Despite the Commonwealth's best efforts to 
    demonstrate continued compliance with the NAAQS, the ambient air 
    pollutant concentrations may exceed or violate the NAAQS. Therefore, 
    the Commonwealth of Kentucky has provided contingency measures with a 
    schedule for implementation in the event of a future O3 air 
    quality problem. The plan contains a contingency to implement RACT on 
    existing major sources in the area where the violation occurred within 
    ninety (90) days. RACT was not required for this nonattainment area 
    because it was designated as a marginal nonattainment area pursuant to 
    the CAA. EPA finds that the contingency measures provided in the 
    Commonwealth of Kentucky's submittal meet the requirements of section 
    175A(d) of the CAA.
    
    E. Subsequent Maintenance Plan Revisions
    
        In accordance with section 175A(b) of the CAA, the Commonwealth of 
    Kentucky has agreed to submit a revised maintenance SIP eight years 
    after the marginal nonattainment areas redesignate to attainment. Such 
    revised SIP will provide for maintenance for an additional ten years.
    
    Final Action
    
        EPA is approving Lexington's O3 maintenance plan because it 
    meets the requirements of section 175A. The EPA is redesignating the 
    Lexington nonattainment area to attainment for O3 because the 
    Commonwealth of Kentucky has demonstrated compliance with the 
    requirements of section 107(d)(3)(E) for redesignation. In addition, 
    EPA is approving the 1990 base year emission inventory for the 
    Lexington nonattainment area. Nothing in this action should be 
    construed as permitting or allowing or establishing a precedent for any 
    future request for revision to any SIP. Each request for revision to 
    the SIP shall be considered separately in light of specific technical, 
    economic, and environmental factors and in relation to relevant 
    statutory and regulatory requirements.
        The O3 SIP is designed to satisfy the requirements of part D 
    of the CAA and to provide for attainment and maintenance of the O3 
    NAAQS. This final redesignation should not be interpreted as 
    authorizing the Commonwealth of Kentucky to delete, alter, or rescind 
    any of the VOC or NOX emission limitations and restrictions 
    contained in the approved O3 SIP. Changes to O3 SIP VOC 
    regulations rendering them less stringent than those contained in the 
    EPA approved plan cannot be made unless a revised plan for attainment 
    and maintenance is submitted to and approved by EPA. Unauthorized 
    relaxations, deletions, and changes could result in both a finding of 
    nonimplementation (section 173(b) of the CAA) and in a SIP deficiency 
    call made pursuant to section 110(a)(2)(H) of the CAA.
        The EPA is publishing this action without prior proposal because 
    the Agency views this as a noncontroversial amendment and anticipates 
    no adverse comments. However, in a separate document in this Federal 
    Register publication, the EPA is proposing to approve the SIP revision 
    should adverse or critical comments be filed. This action will be 
    effective November 13, 1995 unless, by October 11, 1995, adverse or 
    critical comments are received.
        If the EPA receives such comments, this action will be withdrawn 
    before the effective date by publishing a subsequent document that will 
    withdraw the final action. All public comments received will then be 
    addressed in a subsequent final rule based on this action serving as a 
    proposed rule. The EPA will not institute a second comment period on 
    this action. Any parties interested in commenting on this action should 
    do so at this time. If no such comments are received, the public is 
    advised that this action will be effective November 13, 1995.
        Under section 307(b)(1) of the CAA, 42 U.S.C. 7607 (b)(1), 
    petitions for judicial review of this action must be filed in the 
    United States Court of Appeals for the appropriate circuit by November 
    13, 1995. Filing a petition for reconsideration by the Administrator of 
    this final rule does not affect the finality of this rule for 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) of the Act, 42 U.S.C. 7607 (b)(2).)
        The OMB has exempted these actions from review under Executive 
    Order 12866.
        Nothing in this action shall be construed as permitting or allowing 
    or establishing a precedent for any future request for a revision to 
    any SIP. Each request for revision to the SIP shall be considered 
    separately in light of specific technical, economic, and environmental 
    factors and in relation to relevant statutory and regulatory 
    requirements.
        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 businesses, small not-for-profit 
    
    [[Page 47094]]
    enterprises, and government entities with jurisdiction over populations 
    of less than 50,000.
        Redesignation of an area to attainment under section 107(d)(3)(E) 
    of the CAA does not impose any new requirements on small entities. 
    Redesignation is an action that affects the status of a geographical 
    area and does not impose any regulatory requirements on sources. The 
    Administrator certifies that the approval of the redesignation request 
    will not affect a substantial number of small entities.
    
    Unfunded Mandates
    
        Under Sections 202, 203, and 205 of the Unfunded Mandates Reform 
    Act of 1995 (``Unfunded Mandates Act''), signed into law on March 22, 
    1995, EPA must undertake various actions in association with proposed 
    or final rules that include a Federal mandate that may result in 
    estimated costs of $100 million or more to the private sector, or to 
    State, local, or tribal governments in the aggregate.
        Through submission of this state implementation plan or plan 
    revision, the State and any affected local or tribal governments have 
    elected to adopt the program provided for under Section 107 of the 
    Clean Air Act. These rules may bind State, local and tribal governments 
    to perform certain actions and also require the private sector to 
    perform certain duties. To the extent that the rules being approved by 
    this action will impose no new requirements; such sources are already 
    subject to these regulations under State law. Accordingly, no 
    additional costs to State, local, or tribal governments, or to the 
    private sector, result from this action. 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.
