    -----------------------------------------------------------------------
    
    SUMMARY: In this action, the EPA is finalizing its approval of 
    revisions to the Louisiana State Implementation Plan (SIP) for the 
    Baton Rouge ozone nonattainment area. These revisions were submitted by 
    the State of Louisiana for the purpose of satisfying the Post-1996 
    Rate-of-Progress (ROP), Attainment Demonstration, and Contingency Plan 
    requirements of the Federal Clean Air Act (the Act), which will aid in 
    ensuring the attainment of the National Ambient Air Quality Standard 
    (NAAQS) for ozone. The EPA is also approving the associated 1999 Motor 
    Vehicle Emissions Budgets (MVEBs) for the area.
        The EPA is also taking final action to approve additional SIP 
    revisions submitted by Louisiana including codifying revisions that 
    were made to the 1990 base year emission inventory and submitted to the 
    EPA as part of the Baton Rouge 15% Rate-of-Progress Plan approved on 
    October 22, 1996. Furthermore, the EPA is approving additional 
    revisions to the 1990 base year emissions inventory submitted as part 
    of the Post-1996 ROP Plan. The EPA is also approving the State's point 
    source banking regulations. This rulemaking action is being taken under 
    sections 110, 301, and part D of the Act.
    
    EFFECTIVE DATE: This action is effective on August 2, 1999.

    I. Background
    
    A. Summary of Today's Action
    
        The EPA is finalizing approval of revisions to the SIP for the 
    Baton Rouge ozone nonattainment area including the Post-1996 ROP Plan, 
    Attainment Demonstration, and Contingency Plan. In addition, the EPA is 
    approving the associated 1999 MVEBs, revisions to the 1990 base year 
    emission inventory, and the Louisiana Point Source Banking Regulations.
        The EPA proposed approval of these SIP revisions on August 18, 1998 
    (63 FR 44192). The public comment period on the proposed rulemaking 
    ended on October 19, 1998. The EPA received no public comments on its 
    proposal. Accordingly, in today's rulemaking, the EPA is taking final 
    approval action to approve these revisions, which are summarized in the 
    following discussion. For more details on these SIP submittals, 
    relevant Clean Air Act requirements, etc., please refer to the EPA's 
    proposed rulemaking action.
    
    B. Clean Air Act Requirements
    
    1. Reasonable Further Progress (RFP) Requirements
        Section 182(c)(2)(B) of the Act requires each State having one or 
    more ozone nonattainment areas classified as serious or worse to 
    develop a plan by November 15, 1994, that provides for additional 
    actual volatile organic compound (VOC) reductions of at least three 
    percent per year, averaged over each consecutive three year period, 
    beginning six years after enactment of the Act, until such time as 
    these areas have attained the NAAQS for ozone. These plans are referred 
    to hereafter as Post-1996 ROP Plans. These plans were due to be 
    submitted to the EPA as a SIP revision by November 15, 1994.
        Section 182(b)(1) of the Act mandates a 15 percent VOC emission 
    reduction, net of growth, between 1990 and 1996 for each State having 
    one or more ozone nonattainment areas classified as moderate or worse. 
    That SIP revision was due to the EPA by November 15, 1993. The plan for 
    these reductions occurring between 1990-1996 is hereafter referred to 
    as the 15% ROP Plan.
        Sections 182(b)(1)(C), 182(b)(1)(D) and 182(c)(2)(B) of the Act 
    limit the creditability of certain control measures toward the ROP 
    requirements. Specifically, States cannot take credit for reductions 
    achieved by Federal Motor Vehicle Control Program (FMVCP) measures 
    (e.g., new car emissions standards) promulgated prior to 1990, or for 
    reductions stemming from regulations promulgated prior to 1990 to lower 
    the volatility (i.e., Reid Vapor Pressure (RVP)) of gasoline. 
    Furthermore, the Act does not allow credit towards ROP requirements for 
    post-1990 corrections to existing motor vehicle Inspection and 
    Maintenance 
    (I/M) Programs or corrections to Reasonably Available Control 
    Technology (RACT) rules, since these programs were required to be in 
    place prior to 1990. Emissions and emissions reductions shall be 
    calculated on a typical weekday basis for the ``peak'' 3-month ozone 
    period (generally June through August).
    2. Contingency Measures Requirements
        Sections 172(c)(9) and 182(c)(9) of the Act require contingency 
    measures to be included in the ROP and attainment plans. These measures 
    are required to be implemented immediately if reasonable further 
    progress has not been achieved, or if the NAAQS is not met by the 
    deadline set forth in the Act.
    3. Motor Vehicle Emissions Budgets
        Section 176(c) of the Act, and 40 CFR 51.452(b) of the Federal 
    Transportation Conformity Rule require States to establish motor 
    vehicle emissions budgets in any control strategy SIP that is submitted 
    for attainment and maintenance of the NAAQS.
    4. Attainment Demonstration Requirements
        Under section 182(c)(2)(A) of the Act, States required to submit 
    Post-1996 ROP Plans, by November 15, 1994, for serious or worse ozone 
    nonattaiment areas, must also submit for those areas an attainment 
    demonstration to provide for achievement of the ozone NAAQS by the 
    statutory deadline. This demonstration is to be based on photochemical 
    grid modeling, such as the Urban Airshed Model (UAM), or an equivalent 
    analytical method. The reader is referred to the proposal for a 
    discussion of the relevant EPA memoranda on attainment demonstration 
    submissions.
        The Baton Rouge ozone nonattainment area is classified as 
    ``serious'' and is subject to the section 182(b)(1) 15% ROP 
    requirements, section 182(c)(2)(B) Post-1996 ROP requirements, and 
    section 182(c)(2)(A) attainment demonstration requirements. The Baton 
    Rouge ozone nonattainment
    
    [[Page 35932]]
    
    area is comprised of the following parishes: East Baton Rouge, West 
    Baton Rouge, Ascension, Livingston, and Iberville. As a serious ozone 
    nonattainment area, Baton Rouge has a statutory attainment date of 
    November 15, 1999. Therefore, the area's Post-1996 ROP requirement is 
    to achieve an overall 9 percent reduction in actual VOCs (net of 
    growth) during the period 1996-1999 pursuant to section 182(c)(2)(B) of 
    the Act.
    
    C. Related SIP Approvals
    
        As stated previously, section 182(b)(1) of the Act requires that 
    moderate and above ozone nonattainment areas reduce their 1990 
    emissions of VOCs by 15 percent (net of growth) on or before November 
    15, 1996. The 15% ROP Plan submittals were required to be submitted to 
    the EPA by November 15, 1993. The EPA approved Louisiana's 15% ROP Plan 
    on October 22, 1996 (61 FR 54737).
        The following is a summary of the emissions reductions in the 15% 
    ROP Plan:

        Louisiana subsequently submitted a site-specific revision to the 
    approved 15% ROP Plan on December 20, 1997. On May 11, 1998, the EPA 
    approved the 15% ROP Plan revision (63 FR 25773).
        In another rulemaking action, the EPA redesignated Pointe Coupee 
    Parish, which was formerly part of the six-parish Baton Rouge 
    nonattainment area, to attainment for the ozone NAAQS (62 FR 648, dated 
    January 6, 1997). The Baton Rouge area was designated nonattainment for 
    ozone and classified as serious pursuant to sections 107(d)(4) and 
    181(a) of the Act (56 FR 56694, dated November 6, 1991). (It should be 
    noted that, in the August 18, 1998, proposal, the EPA did not reopen or 
    request comment on the approval actions described in this section.)
    
    D. Current SIP Submittals
    
        In a letter from the Governor dated November 10, 1994, the State of 
    Louisiana submitted to the EPA the Post-1996 ROP Plan and attainment 
    demonstration according to section 182(c)(2). The combined plan 
    submittal addressed both the 9 percent VOC emissions reduction 
    requirement and the requirement to demonstrate attainment of the ozone 
    NAAQS by the area's statutory attainment date, November 15, 1999. The 
    SIP submittal was deemed administratively complete on May 15, 1995, by 
    operation of law pursuant to section 110(k)(1)(B) of the Clean Air Act.
        Subsequently, on December 22, 1995, the Governor of Louisiana 
    submitted revisions to the November 10, 1994, submittal. The EPA 
    determined that, in effect, this revised Post-1996 ROP Plan and 
    Attainment Demonstration superseded the previous submittal.1 
    The plan was determined to be administratively complete on March 22, 
    1996. The revisions that Louisiana made to the plan substantially 
    modified the mix of control measures utilized to satisfy the 9% ROP 
    requirement, and also made changes to the attainment demonstration 
    based on the EPA's draft guidance document on attainment modeling 
    entitled, Guidance on Use of Modeled Results to Demonstrate Attainment 
    of the Ozone NAAQS. As provided for by the draft guidance document on 
    modeling, the submittal included a weight-of-evidence determination in 
    support of the urban airshed modeling results.
    ---------------------------------------------------------------------------
    
        \1\ In this submittal, the State deleted several of the 
    appendices found in the previous submittal and substantially revised 
    the remaining portion of the plan (i.e., control strategy, modeling 
    demonstration, etc.). The December 22, 1995, submittal is capable of 
    standing alone and does not rely on the November 10, 1994, submittal 
    to be a complete plan. As such, the EPA's legal obligation to act on 
    the State's original Post-1996 ROP Plan/Attainment Demonstration 
    submittal, dated November 10, 1994, is rendered moot.
    ---------------------------------------------------------------------------
    
        Finally, on January 2, 1997, the Governor of Louisiana submitted a 
    revision to the December 22, 1995, submittal. The 1997 submittal 
    included significant changes to the 1990 base year emissions inventory 
    (and associated 15% and 9% ROP reductions) to account for the impending 
    redesignation of Pointe Coupee Parish to ozone attainment. Also, the 
    1997 submittal incorporated into the 1990 base year emissions inventory 
    previously unreported emissions from several point sources. In 
    addition, the 1997 submittal removed the emission reduction credits 
    taken for the vehicle I/M control measure in the December 22, 1995, 
    submittal, and replaced them with additional point source emission 
    reductions. Furthermore, the submittal incorporated enhanced mobile 
    modeling required by Federal conformity regulations, and also included 
    an analysis of how removal of the I/M reductions would impact the 
    modeling results submitted in the December 22, 1995, attainment 
    demonstration. The 1997 submittal was determined to be administratively 
    complete on June 20, 1997.
        In addition, Louisiana submitted its contingency measure, point 
    source emissions reduction banking
    
    [[Page 35933]]
    
    regulations, as part of the December 15, 1995, 15% ROP Plan pursuant to 
    sections 172(c)(9) and section 182(c)(9) of the Act. The State 
    subsequently submitted the same contingency measure in both the 
    December 22, 1995, and January 2, 1997, Post-1996 ROP/attainment 
    demonstration submittals. The EPA deferred taking action on the 
    regulations in the context of the 15% ROP Plan approval until its 
    rulemaking action on the Post-1996 ROP Plan/attainment demonstration 
    SIP. (The rationale is explained in more detail in the EPA's rulemaking 
    on the 15% ROP Plan, along with the associated Technical Support 
    Document (TSD).)
    
    II. Analysis of the Submittals
    
        The EPA has reviewed the State's submittals for consistency with 
    the Act and applicable EPA regulations and policy. A summary of the 
    EPA's analysis is provided below. More detailed support and technical 
    discussion are contained in the proposed rulemaking and associated TSD 
    entitled, ``TSD for Proposed Clean Air Act Approval and Promulgation of 
    the Post-1996 Rate-of-Progress Plan and Attainment Demonstration for 
    the Baton Rouge Ozone Nonattainment Area (July 1998).''
    
    A. Post-1996 Rate-of-Progress Plan
    
    1. Introduction
        As stated previously, section 182(c)(2)(B) of the Act requires each 
    serious and above ozone nonattainment area to submit a SIP revision by 
    November 15, 1994, which provides for an actual reduction in VOC 
    emissions of at least three percent per year averaged over each 
    consecutive 3-year period, beginning 6 years after enactment of the 
    Clean Air Act Amendments of 1990 (CAAA), until the area attains the 
    ozone standard.
    2. Base Year Emissions Inventory
        Under section 182(b)(1)(B), the baseline from which States 
    determine the required reductions for ROP planning is the 1990 base 
    year emissions inventory. The inventory is broken down into several 
    emissions source categories: stationary, area, on-road mobile, off-road 
    mobile, and biogenics. The EPA originally approved the Louisiana 1990 
    base year emissions inventory on March 15, 1995 (60 FR 13911).
        Louisiana's December 15, 1995, submittal made a number of 
    adjustments to the base year inventory. The EPA acted upon the revised 
    1990 base year inventory as part of its rulemaking on the 15% ROP Plan. 
    In that rulemaking, however, the EPA failed to codify its approval of 
    the revised base year inventory in the Code of Federal Regulations 
    (CFR) (specifically, 40 CFR part 52). In this rulemaking, the EPA is 
    taking final action to codify its approval of the revised base year 
    inventory (in the context of the rulemaking on the 15% ROP Plan). It 
    should be noted that, in the August 18, 1998, proposal, the EPA did not 
    reopen or ask for comment on its March 15, 1995, approval of the base 
    year inventory.
        Louisiana's January 2, 1997, submittal made a number of additional 
    revisions to the 1990 base year emissions inventory. The following 
    table compares the revised 1990 base year VOC emissions cited in the 
    January 2, 1997, submittal, with those cited in the approved 15% Plan 
    rulemaking.

    ----------------------------------------------------------------------------------------------------------------
    
        The bases for these changes to the inventory were discussed in 
    detail in the EPA's proposed rulemaking.
        The EPA is taking final action to approve the revised 1990 base 
    year emissions inventory submitted on January 2, 1997.
        Overall, these revisions to the 1990 base year inventory decrease 
    the ``1990 ROP inventory,'' which is the 1990 base year inventory less 
    the biogenic emissions, for the Baton Rouge nonattainment area from 
    220.4 tons/day to 215.6 tons/day. The decrease of 4.8 tons/day in the 
    1990 ROP inventory reduces the 15% ROP Plan reductions requirement by 
    .6 tons/day. Since the reductions in the approved 15% ROP Plan have 
    remained unchanged, Louisiana added the .6 tons/day differential to the 
    15% Plan surplus reductions resulting in a total surplus of 3.2 tons/
    day available to be carried over to the Post-1996 ROP Plan. The EPA has 
    determined this revised surplus to be acceptable for use in the Post-
    1996 ROP Plan.
    3. Adjusted Base Year Inventory
        Section 182(c)(2)(B) states that the rate-of-progress reductions 
    must be achieved ``from the baseline emissions described in subsection 
    182(b)(1)(B).'' This baseline value is termed the 1990 adjusted base 
    year inventory. Section 182(b)(1)(B) defines baseline emissions (for 
    the purposes of calculating each milestone VOC/nitrogen oxides (NOx) 
    emissions reduction) as ``the total amount of actual VOC or NOx 
    emissions from all anthropogenic sources in the area during the 
    calendar year of enactment.'' This section excludes from the baseline 
    the emissions that would be eliminated by FMVCP regulations promulgated 
    by January 1, 1990, and the RVP regulations promulgated by the time of 
    enactment (at 55 FR 23666, June 11, 1990), which require maximum RVP 
    limits for gasoline to be sold in nonattainment areas during the peak 
    ozone season.
        In the August 18, 1998, proposal, the EPA provided a detailed 
    explanation of the methodology for calculating the FMVCP/RVP 
    adjustment. The EPA is taking final action to approve the FMVCP/RVP 
    adjustment factor and the inventories discussed above, as follows:
    
    ------------------------------------------------------------------------
                         Emissions inventory                        Tons/Day
    ------------------------------------------------------------------------
    A. 1990 Base Year Emissions Inventory........................      315.2
    B. 1990 Rate-of-Progress Inventory (Base Year--Biogenics)....      215.6
    C. Emissions Reductions from the Pre-1990 FMVCP and Phase II        24.4
     RVP Expected by 1999........................................
    D. 1990 Adjusted Base Year Inventory (B-C)...................      191.2
    ------------------------------------------------------------------------
    
    4. Required Rate-of-Progress Reductions
        The next step is then to calculate the Post-1996 ROP reductions 
    requirement. In order to do so, the 1990 adjusted base
    
    [[Page 35934]]
    
    year VOC inventory is multiplied by nine percent. Thus, the Post-1996 
    ROP reduction requirement is 17.2 tons/day (.09  x  191.2). The EPA has 
    determined the State's calculation of the Post-1996 ROP reduction 
    requirement to be acceptable.
    5. Fleet Turnover Correction Term
        In the absence of any new requirements of the CAAA, some decrease 
    in motor vehicle emissions will occur automatically due to fleet 
    turnover. States are not allowed to take credit for these reductions 
    for ROP purposes. During the State's calculation of the 1996 target 
    level of emissions, these FMVCP reductions, along with non-creditable 
    RVP reductions that would occur between 1990 and 1996, were subtracted 
    from the 1990 ROP inventory to calculate the 1990 adjusted base year 
    inventory. This 1990 adjusted base year inventory was then used to 
    calculate the required reductions and the 1996 target level of 
    emissions.
        Between 1996 and 1999, there will be some additional reductions in 
    emissions due to fleet turnover that are not creditable. These 
    additional, non-creditable reductions are referred to as the fleet 
    turnover correction term. The fleet turnover correction term is the 
    difference between the 1999 and 1996 FMVCP/RVP mobile source 
    reductions, or 3.0 tons/day. The EPA has determined the fleet turnover 
    correction term in the Baton Rouge Post-1996 ROP Plan to be acceptable.
    6. Calculation of Target Level of Emissions
        For the purpose of calculating the 1999 target, the 1996 target 
    inventory (obtained from the 15% ROP Plan calculations) is used. The 
    1996 target inventory used by the State in this calculation was revised 
    from the target inventory approved as part of the 15% ROP Plan 
    rulemaking in order to account for the changes made to the 1990 base 
    year inventory described in detail in the August 18, 1998, proposal. 
    The EPA is taking final action to approve the State's revised 1996 
    target level of emissions of 163.8 tons/day.
        The 1999 target level of emissions is the amount of VOC emissions 
    that must be achieved in order for the nonattainment area to 
    demonstrate that the 9% ROP requirement has been met. The 1999 target 
    level used by the State in the Post-1996 ROP Plan is the revised 1996 
    target level (163.8 tons/day), less the 9% ROP reductions (17.2 tons/
    day), less the fleet turnover correction term (3.0 tons/day), or 143.6 
    tons/day. The EPA is taking final action to approve the State's 1999 
    target level of emissions of 143.6 tons/day.
    7. Growth Calculations
        a. Introduction. The EPA has interpreted the Act to require that 
    States must provide for sufficient control measures in their ROP Plans 
    to offset any emissions growth expected to occur after 1996. Therefore, 
    to meet the ROP requirement, a State must provide for sufficient 
    emissions reductions to offset projected growth in emissions in 
    addition to the three percent annual average reduction of VOC 
    emissions. Thus, an estimate of growth in emissions from 1996 to 1999 
    is required for determining the total amount of required reductions in 
    the Post-1996 ROP Plan.
        b. EPA Action. In the August 18, 1998, proposal, the EPA provided a 
    detailed description of the methodology the State followed for 
    projecting growth in each source category during the period 1996-1999.
        The following Table summarizes the projected emissions growth by 
    source category for the nonattainment area:
    
                          BATON ROUGE GROWTH, 1996-1999

                                                                 -----------
    Total Growth in 9% Plan.....................................        2.8
    ------------------------------------------------------------------------
    
        The EPA has determined that the State's methodology for estimating 
    emissions growth for the period 1996-1999 is acceptable.
    8. Total Required Reductions
        The total required reductions in the plan include the 9% ROP 
    reductions, reductions to offset projected growth (1996-1999), and the 
    FMVCP/RVP turnover correction reductions (1996-1999). These required 
    reductions total 23.0 tons/day. The State's ``share'' of the required 
    reductions consists of the 9% ROP reductions (17.2 tons/day) plus the 
    growth offset (2.8 tons/day), or 20.0 tons/day. The FMVCP/RVP turnover 
    correction reductions (3.0 tons/day) are the Federal reductions that 
    are not creditable towards meeting the ROP/growth offset requirements.
    9. Measures to Achieve the Required Reductions
        a. Introduction. As described in the August 18, 1998, proposed 
    rulemaking, the State relied on a combination of surplus emission 
    reductions from the 15% ROP Plan, along with additional control 
    measures to achieve the emissions reductions required for the Post-1996 
    ROP Plan. The EPA has determined that both the surplus reductions from 
    the 15% ROP Plan and the emissions reductions claimed from the control 
    measures in the Post-1996 ROP Plan are acceptable for meeting the 9% 
    (net of growth) emissions reductions requirement. The reader is 
    referred to the proposal and associated TSD for a detailed description 
    of the control measures and their associated reductions, which are 
    summarized below:

    b. EPA Action. The EPA is taking final action to approve the 
    emissions reductions claimed in the January 2, 1997, Post-1996 ROP 
    Plan as creditable towards the 9% ROP requirements of section 
    182(C)(2)(B) of the Act. The EPA is also approving into the SIP the 
    Borden Chemical and Plastics Reasonable Further Progress Agreed To 
    Order. The barge cleaner permit modification was issued under a 
    SIP-approved nonattainment new source review program and is, 
    therefore, already part of the Louisiana SIP and Federally 
    enforceable. In addition, the State's waste gas regulation (LAC 
    33:III.2115), which requires controls on glycol dehydrators and 
    vent streams, has already been approved into the SIP.
    
    B. Motor Vehicle Emissions Budgets
    
    1. Introduction
        As stated previously, section 176(c) of the Act, and the Federal 
    Transportation Conformity Rule require States to establish motor 
    vehicle emissions budgets in any control strategy SIP that is submitted 
    for attainment and maintenance of the NAAQS. Louisiana submitted, in 
    the January 2, 1997, Post-1996 ROP Plan, projected (1999) motor vehicle 
    emissions budgets for VOC and NOX for the 5-parish Baton 
    Rouge ozone nonattainment area.
        Specifically, for the 5-parish serious ozone nonattainment area, 
    the State established the following VOC/NOX mobile vehicle 
    emissions budgets:
    
              Baton Rouge, LA 1999 Motor Vehicle Emissions Budgets
    ------------------------------------------------------------------------
                     Pollutant                        Budget (Tons/Day)
    ------------------------------------------------------------------------
    VOC.......................................  33.93
    NOx.......................................  58.03
    ------------------------------------------------------------------------
    
    2. EPA Action
        The EPA has determined that the State's methodology for projecting 
    the 1999 motor vehicle VOC and NOX emissions is acceptable. 
    Therefore, the EPA is taking final action to approve the figures in the 
    above table as the official 1999 MVEBs to be used for transportation 
    conformity determinations.
    
    C. Contingency Measures
    
    1. Introduction
        Under section 172(c)(9) of the Act, ozone nonattainment areas 
    classified as moderate or above must submit contingency measures to be 
    implemented if RFP is not achieved or if the standard is not attained 
    by the applicable attainment date. The ``General Preamble for the 
    Implementation of Title I of the Clean Air Act Amendments of 1990'' (57 
    FR 13498, April 16, 1992) states that the contingency measures should, 
    at a minimum, ensure that an appropriate level of emissions reduction 
    progress continues to be made if attainment or RFP is not achieved in a 
    timely manner and additional planning by the State is needed.
        In the General Preamble, the EPA interpreted the Act to require 
    States with moderate and above ozone nonattainment areas to include 
    sufficient contingency measures in their November 1993 submittals so 
    that, upon implementation of such measures, additional emissions 
    reductions of up to three percent of the emissions in the adjusted base 
    year inventory (or a lesser percentage that will cure the identified 
    failure) would be achieved in the year following the year in which the 
    failure has been identified. States must show that their contingency 
    measures can be implemented with minimal further action on their part 
    and with no additional rulemaking actions such as public hearings or 
    legislative review.
        Additional contingency provisions are included in section 182(c)(9) 
    for serious ozone nonattainment areas. These latter provisions are 
    similar to the section 172(c)(9) requirements except that the focus in 
    section 182 (Ozone Areas) is on meeting emissions reductions milestones 
    (section 182(g)).
    2. Point Source Emissions Banking
        Louisiana identified, in both its 15% and Post-1996 ROP Plans 
    submittals, the State's point source VOC/NOX banking 
    regulations (LAC 33:III sections 601, 603, 605, 607, 613, 615, 617, 
    619, 621, 623, and 625) 2 as the three percent contingency 
    measure. These banking regulations are intended to meet the contingency 
    measure requirements of both section 172(c)(9) and section 182(c)(9) of 
    the Act. The adopted point source banking regulations were initially 
    submitted to the EPA for approval in the December 15, 1995, 15% ROP 
    Plan submittal. The EPA deferred taking action on the regulations in 
    the context of the 15% ROP Plan approval until its rulemaking action on 
    the Post-1996 ROP Plan/Attainment Demonstration SIP. (The rationale for 
    ``carving out'' the contingency measures was explained in detail in the 
    TSD to the August 18, 1998, proposed rulemaking, as well as the TSD to 
    the 15% ROP Plan rulemaking.) The reader is referred to the EPA's 
    proposal for an in-depth discussion of the point source banking 
    regulations.
    ---------------------------------------------------------------------------
    
        \2\ It should be noted that, in the preamble discussion to its 
    August 18, 1998, proposal (pp. 44200 and 44207), the EPA's 
    description of the State's submission inadvertently left out 
    references to certain sections of the point source banking 
    regulations submitted by the State. The correct sections, however, 
    were actually discussed (generally and/or specifically) elsewhere in 
    the proposal/TSD and are correctly set out in the preamble to this 
    final rule.
    ---------------------------------------------------------------------------
    
        In the December 22, 1995, Post-1996 ROP Plan submittal, the State 
    provided a table of the emissions reductions that had been banked by 
    industry to date pursuant to the regulations. The State's contingency 
    measure requirement is 5.7 tons/day of VOCs (three percent times the 
    adjusted base year inventory of 191.2 tons/day). The VOC reductions 
    ``on deposit,'' 13.0 tons/day, are well in excess of the three percent 
    requirement.
        The EPA has determined that the State has met the contingency 
    measures requirements by having adopted and
    
    [[Page 35936]]
    
    submitted the point source banking regulations, and demonstrating the 
    bank has sufficient VOC credits ``on deposit'' and available for 
    confiscation in the event of a missed milestone/failure to attain. 
    Furthermore, the EPA has determined that the banking rules provide for 
    expeditious implementation of the contingency measures consistent with 
    the time frames identified in the General Preamble.
        As mentioned in the August 18, 1998, proposal, Louisiana also 
    submitted to the EPA, in the January 2, 1997, submittal, a correction 
    to a typographical error in section 615, ``Schedule for Submitting 
    Applications.'' The EPA is taking final action to also approve this 
    correction to the point source banking rules.
    3. EPA Action
        The EPA is taking final action to approve the already-banked VOC 
    emissions reductions credits (totaling 5.7 tons/day) toward meeting the 
    three percent contingency measure requirement pursuant to sections 
    172(c)(9) and 182(c)(9) of the Act.
        The EPA has determined that the point source VOC/NOX 
    banking regulations are generally consistent with the Act, EPA policy/
    guidance and Federal regulations. Therefore, the EPA is taking final 
    action to approve the State's banking regulations as meeting the 
    requirements for SIP approval under part D and section 110 of the Act.
        It should be noted that the scope of this final rulemaking is to 
    approve the banked VOC emissions reductions as creditable toward the 
    contingency measures pursuant to sections 172(c)(9) and 182(c)(9) of 
    the Act, and to approve all of the point source banking regulations as 
    an acceptable SIP revision pursuant to part D and section 110 of the 
    Act. The EPA is not, however, approving the banking regulations as an 
    economic incentive program (EIP) pursuant to the EPA's Economic 
    Incentives Program Rules (59 FR 16690) and section 182(g) of the Act. 
    (Since the State has not expressly submitted the point source banking 
    regulations as a section 182(g) SIP revision, the EPA believes it 
    beyond the scope of this rulemaking to act upon the banking regulations 
    as an EIP.)
    
    D. Additional Rule Submitted
    
        The State elected to include regulation LAC 33:III.611, ``Mobile 
    Sources Emissions Reductions,'' in the January 2, 1997, submittal for 
    the EPA's approval as part of the overall emissions banking program. 
    However, the State is not taking any reduction credit in the 
    contingency plan from this voluntary mobile source emissions reduction 
    program. In fact, no vehicles have actually been scrapped to date under 
    the program and, hence, no mobile emission reduction credits have been 
    banked statewide as part of the vehicle scrappage program.
        Since the State's submission of section 611, certain national 
    policy issues have arisen surrounding the use of mobile source-
    generated emissions reductions credits for use by point sources. 
    Pending resolution of these issues, the EPA is deferring taking action 
    on the regulation at this time. The deferral will have no effect on 
    either the Post-1996 ROP Plan or the Attainment Demonstration since the 
    State is not relying on reductions from the vehicle scrappage program 
    to meet the reductions target or demonstrate attainment. (A more in-
    depth discussion of the EPA's rationale for deferring action on the 
    rule was provided in the TSD to the August 18, 1998, proposed 
    rulemaking.)
    
    E. Attainment Demonstration
    
    1. Introduction
        As stated previously, section 182(c)(2)(A) of the Act stipulates 
    that serious and above ozone nonattainment areas must submit a revision 
    to the SIP that includes a demonstration that the plan, as revised, 
    will provide for attainment of the NAAQS for ozone by November 15, 
    1999. In addition to the 15% and 9% (net of growth) ROP reductions 
    requirements, if the mandatory emission reductions are not sufficient 
    to demonstrate attainment of the ozone NAAQS by November 15, 1999, 
    emissions (VOCs and/or NOX) must be further reduced until 
    attainment is demonstrated through photochemical grid modeling.
        For ozone nonattainment areas classified as serious or above, 
    section 182(c)(2)(A) of the Act requires an attainment demonstration 
    based on photochemical grid modeling, for which the Urban Airshed Model 
    (UAM) is the EPA-approved model. See appendix W of 40 CFR part 51.
        The following guidance documents establish the acceptable 
    techniques for application of UAM to demonstrate attainment of the 
    ozone NAAQS:
    
    EPA's Guideline on Air Quality Models (Revised) (July 1986);
    EPA's Guideline for Regulatory Application of the UAM (July 1991); and
    EPA's final Guidance on use of Modeled Results to Demonstrate 
    Attainment of the Ozone NAAQS (June 1996).
    
        The UAM model uses an inventory of pollutant emissions, together 
    with air quality and meteorological data, as input to a system of 
    algorithms incorporating chemistry and dispersion, in order to simulate 
    an observed pollution episode. Once a ``base case'' is developed that 
    meets the minimum performance criteria, projected future emissions are 
    used as input to simulate air quality in the attainment deadline year. 
    Various combinations of geographically uniform emission reductions are 
    simulated to determine approximate attainment reduction targets. 
    Planners design a control strategy to meet these targets, and then 
    simulate it with UAM, including the spatially and temporally varying 
    effects of the selected controls. Attainment is demonstrated when the 
    modeled air quality with emission controls in effect is below the NAAQS 
    throughout the geographical modeling domain.
        The EPA's Guidance on the Use of Modeled Results to Demonstrate 
    Attainment of the Ozone NAAQS allows States to use a ``weight-of-
    evidence'' determination if the modeled attainment test is not fully 
    passed, showing that attainment of the NAAQS is still likely. (The 
    reader is referred to the EPA's proposal for a detailed discussion of 
    UAM modeling procedures and requirements.)
    2. EPA Action
        The EPA's review focused on the data sources used, technical 
    judgments, and procedures followed in input preparation and performing 
    quality assurance and diagnostics. The EPA also evaluated the model's 
    base case performance, consistency of control measure simulation inputs 
    with submitted control measures, adequacy of the demonstration of 
    attainment of the NAAQS, and the consistency/completeness of the 
    modeling documentation.
        a. Episode Selection and Base Case Performance. As explained in the 
    Guideline for the Regulatory Application of the Urban Airshed Model, 
    episodes are chosen for modeling based on their high ozone levels, data 
    availability and other criteria. Generally, episodes should be chosen 
    that are approximately as severe as the area's design value, which is 
    based on historical ozone highs. During a particular episode, the 
    observed ozone peak may be higher or lower than the design value; but 
    as long as it is relatively close, that episode can be accepted for use 
    in an attainment demonstration.
        The Guideline for the Regulatory Application of the Urban Airshed 
    Model calls for a minimum of three primary episode days to be modeled. 
    The EPA
    
    [[Page 35937]]
    
    may allow areas to use just two episode days if they are based on a 
    field study, since this provides substantially more complete data, and, 
    hence, more confidence in model development procedures and results. In 
    the case of the Baton Rouge demonstration, the State modeled three 
    primary episode days.
        The following three episodes were selected for use in the December 
    22, 1995, Baton Rouge Attainment Demonstration SIP submittal: August 
    15-16, 1989, May 24-25, 1990; and August 18-19, 1993.
        Once the episodes were chosen, the modelers are required to 
    simulate these observed pollution episodes using the urban airshed 
    model. In conducting the Baton Rouge base case model performance 
    evaluation, the State employed both graphical and statistical 
    performance measures to gauge their success. (A discussion of the 
    graphical and statistical tests used in the evaluation of the Baton 
    Rouge modeling demonstration was provided in the EPA's August 18, 1998, 
    proposal and associated TSD.) In the Baton Rouge base case simulations, 
    the model performance for the August 15-16, 1989, and August 18-19, 
    1993, episodes was rated ``good,'' and the model performance for the 
    May 24-25, 1990, episode was rated ``very good.'' The EPA has 
    determined that the Baton Rouge episodes had acceptable performance and 
    met the Guideline criteria.
        b. Attainment Test. The Guidance on use of Modeled Results to 
    Demonstrate Attainment of the Ozone NAAQS (June 1996) identifies two 
    approaches that the State can use for demonstrating attainment of the 
    ozone NAAQS. One of the acceptable approaches is called the 
    ``Deterministic Approach,'' which consists of a deterministic test and 
    an optional weight-of-evidence determination. The deterministic test is 
    passed if predicted maximum ozone concentrations are less than or equal 
    to 124 parts per billion (ppb) in all surface grid cells on all modeled 
    primary episode days. If the test is not passed, a weight-of-evidence 
    determination may be used to show that attainment of the NAAQS is still 
    likely.
        Meanwhile, the second acceptable approach is called the 
    ``Statistical Approach.'' This approach consists of two parts: a 
    statistical test and a weight-of-evidence determination. The 
    statistical test includes three benchmarks. The first benchmark limits 
    the number of allowed exceedences, the second restricts the magnitude 
    of an allowed exceedence, and the third requires a minimum level of 
    improvement in air quality to be exceeded. If one or more of the 
    benchmarks is failed, a weight-of-evidence determination may also be 
    performed using corroborative information. If the corroborative 
    information is consistent with the likelihood that a proposed strategy 
    will lead to attainment of the ozone NAAQS by statutory dates, 
    attainment has been demonstrated.
        As discussed in detail in the EPA's August 18, 1998, proposal, the 
    State elected to follow the ``Statistical Approach,'' consisting of a 
    statistical test and weight-of-evidence determination, for 
    demonstrating attainment of the ozone NAAQS through UAM modeling.
        c. Photochemical Grid Model Used. The State used UAM Version IV, an 
    EPA-approved photochemical grid model, to develop the attainment 
    demonstration for the Baton Rouge area. The State performed its 
    modeling activities as outlined in the UAM modeling protocols and 
    according to the EPA's Guideline for Regulatory Application of the 
    Urban Airshed Model. (In advance of performing the UAM analyses, the 
    State developed a specific protocol for conducting its modeling 
    activities, which EPA reviewed and approved.)
        The Baton Rouge modeling domain covers all or part of 20 parishes 
    in Louisiana, including the Baton Rouge serious ozone nonattainment 
    area consisting of East Baton Rouge, West Baton Rouge, Livingston, 
    Iberville, and Ascension Parishes.
        The EPA has determined that the State followed acceptable 
    procedures to develop the meteorological and air quality inputs, base 
    case emissions inventories, projection inventories, and future boundary 
    conditions used in the UAM modeling. (The reader is referred to the 
    EPA's proposal for a more in-depth discussion of the methodology the 
    State followed in developing these model inputs.)
        d. Demonstration of Attainment. The EPA's Guideline for the 
    Regulatory Application of the Urban Airshed Model stipulates that, for 
    the primary episode days modeled, there should be no predicted daily 
    maximum ozone concentrations greater than 124 ppb anywhere in the 
    modeling domain for each primary episode day modeled. However, in its 
    subsequent Guidance on the Use of Modeled Results to Demonstrate 
    Attainment of the Ozone NAAQS (June 1996), the EPA revised the model 
    test for demonstrating attainment of ozone NAAQS. (The revisions were 
    intended to make the modeled attainment test more closely reflect the 
    form of the NAAQS.) In the Guidance, the EPA recommended that either 
    the ``Statistical Approach'' or ``Deterministic Approach'' should be 
    used for the attainment demonstration of the ozone NAAQS. (These 
    approaches were discussed in detail in the proposed rulemaking.)
        As stated above, the State elected to use the ``Statistical 
    Approach,'' consisting of a statistical test with optional weight-of-
    evidence determination, to demonstrate attainment of the ozone NAAQS. 
    The statistical test included the application of three benchmark tests. 
    The weight-of-evidence determination entailed the use of supplementary 
    analyses to determine whether attainment was likely, despite model 
    results which did not pass the statistical test.
        The State used the three selected episodes, all having good to very 
    good base case model performance ratings, for demonstrating attainment 
    of the ozone NAAQS. These episodes were modeled using the projected 
    1999 emission inventory, which included the emission controls to be 
    implemented through 1999. The results of the various benchmark tests 
    are discussed in detail in the August 18, 1998, proposed rulemaking.
        e. Modeling Evaluation. The EPA has determined that the State's 
    attainment demonstration for the Baton Rouge ozone nonattainment area 
    fulfills the requirements of section 182(c)(2)(A) of the Act. The State 
    adequately followed the EPA's guidance on the application of the UAM 
    for demonstrating attainment of the ozone NAAQS. Following the 
    ``Statistical Approach,'' it demonstrated that two of the three 
    episodes met or nearly met all the specified benchmark criteria. 
    Furthermore, supplementary information provided by the State for 
    consideration in the weight-of-evidence determination (i.e., mid-course 
    review, severity of selected episodes, uncertainty in the boundary 
    condition estimates, etc.) supported the modeled attainment 
    demonstration.
        The Guidance on the Use of Modeled Results to Demonstrate 
    Attainment of the Ozone NAAQS also allows the use of normalized trend 
    data, results from observational models and or other models and 
    consideration of incremental cost/benefit estimates, etc., in a weight-
    of-evidence determination. In determining whether the State's 
    ``Statistical Approach'' to demonstrating attainment was adequate, the 
    EPA considered general trend data, which reflected reductions in 
    monitored ozone values, precursor emissions, and total exceedence days 
    since 1990.
    
    [[Page 35938]]
    
        As stated previously under ``Current SIP Submittals,'' the State, 
    in its January 2, 1997, submittal, removed the emission reduction 
    credits taken for the vehicle inspection and maintenance control 
    measure included in the December 22, 1995 Post-1996 ROP Plan submittal, 
    and replaced them with additional point source reductions. The January 
    2, 1997, submittal provided an analysis of how removal of the I/M 
    reductions would impact the modeling results submitted in the December 
    22, 1995, attainment demonstration. The EPA reviewed the State's 
    analysis and concurred that removal of the I/M reductions from the plan 
    would not significantly alter the modeling results.
        In summary, based on the results of the statistical test, the 
    weight-of-evidence determination, and the I/M impact analysis, the EPA 
    has determined that State adequately demonstrated the modeled control 
    strategy would provide for attainment of the ozone NAAQS by the 
    statutory attainment date.
        f. Control Strategy Evaluation. The EPA has determined that the 
    modeling results for Baton Rouge adequately demonstrate that the area 
    could attain the ozone standard by 1999 through the implementation of a 
    VOC-only control strategy consisting of the Federally enforceable 15 
    Percent and Post-1996 ROP VOC reductions (net of growth) from the 1990 
    base year levels. The reader is referred to the proposed rulemaking for 
    a more in-depth discussion of the control strategy modeled.
        The EPA is taking final action to approve Louisiana's Attainment 
    Demonstration SIP submittals, dated December 22, 1995, and January 2, 
    1997, as meeting the requirements of section 182(c)(2)(A) of the Act 
    for demonstrating attainment of the NAAQS for ozone by November 15, 
    1999. Through photochemical grid modeling, the State has demonstrated 
    to the EPA's satisfaction that the VOC reductions in the 15% and Post-
    1996 ROP Plans (34.8 and 21.4 3 tons/day, respectfully) are 
    sufficient to demonstrate attainment of the ozone NAAQS by the 
    statutory deadline.
    ---------------------------------------------------------------------------
    
        \3\ The 21.4 tons/day in emissions reductions includes the 3.2 
    tons/day surplus reductions from the 15% ROP Plan carried over to 
    the Post-1996 ROP Plan.
    ---------------------------------------------------------------------------
    
    III. Final Rulemaking Action
    
        The EPA has reviewed the SIP submittals for consistency with the 
    Act, applicable EPA regulations and EPA policy, and is approving the 
    following under sections 110(k)(3), 301(a), and part D of the Act:
        A. The Baton Rouge, Louisiana, Post-1996 Rate-of-Progress Plan, 
    submitted December 22, 1995, and revised January 2, 1997, as meeting 
    the requirements of section 182(c)(2)(B) of the Act to achieve a 
    reduction in VOC emissions (net of growth) of 9 percent between 1996 
    and 1999.
        B. The Baton Rouge, Louisiana, contingency plan, initially 
    submitted as part of the 15% ROP Plan on December 15, 1995, and, 
    subsequently, as part of the Post-1996 ROP Plan submitted December 22, 
    1995, and revised January 2, 1997. The EPA is taking final action to 
    approve the contingency plan as meeting the requirements of sections 
    172(c)(9) and 182(c)(9) of the Act that moderate and above ozone 
    nonattainment areas include contingency measures in their ROP Plan 
    submittals. Specifically, the EPA is taking final action to approve the 
    contingency-reserved VOC banked emissions reductions of 5.7 tons/day 
    (achieved through the State's banking regulations), identified in a 
    table in appendix T of the December 22, 1995, submittal, as creditable 
    towards the 3 percent contingency requirements of sections 172(c)(9) 
    and 182(c)(9) of the Act. In addition, the EPA is taking final action 
    to approve the point source VOC and NOX emissions reductions 
    banking regulations (LAC 33:III sections 601, 603, 605, 607, 613, 615, 
    617, 619, 621, 623, and 625) submitted December 15, 1995, and revised 
    January 2, 1997, as meeting the requirements for SIP approval under 
    part D and section 110 of the CAAA.
        C. The 1999 Motor Vehicle Emissions Budgets for on-road mobile VOC 
    and NOX emissions for the Baton Rouge 5-parish ozone 
    nonattainment area submitted January 2, 1997, as meeting the 
    requirements of section 176(c) of the Act and 40 CFR 51.452(b) of the 
    Federal Transportation Conformity Rule.
        D. The Baton Rouge, Louisiana Attainment Demonstration submitted 
    December 22, 1995, and revised January 2, 1997, including the modeling 
    analyses, as meeting the requirements of section 182(c)(2)(A) of the 
    CAAA to provide for attainment of the ozone NAAQS by the applicable 
    November 15, 1999, attainment date.
        E. Revisions to the 1990 base year VOC emissions inventory 
    submitted January 2, 1997 as meeting the requirements of section 
    182(a)(1) of the Act. In addition, the EPA is taking final action to 
    codify the revisions to the 1990 base year emissions inventory 
    submitted as part of the 15% ROP Plan approved October 22, 1996 (61 FR 
    54737).
        F. The revision to the 1996 target level of VOC emissions submitted 
    January 2, 1997, as meeting the requirements of part D and EPA 
    guidance.
        The EPA is deferring taking any action at this time on the State's 
    accelerated vehicle retirement regulation (LAC 33:III.611) entitled, 
    ``Mobile Sources Emission Reductions,'' which was submitted to the EPA 
    on January 2, 1997. Deferring action on this regulation has no effect 
    on either the Baton Rouge Post-1996 ROP Plan or on the Baton Rouge 
    Attainment Demonstration since the State took no credit in these plans 
    for reductions from vehicle scrappage.
    
    IV. Administrative Requirements
    
    A. Executive Order (E.O.) 12866
    
        The Office of Management and Budget (OMB) has exempted this 
    regulatory action from E.O. 12866, entitled ``Regulatory Planning and 
    Review.''
    
    B. Executive Order 12875
    
        Under E.O. 12875, EPA may not issue a regulation that is not 
    required by statute and that creates a mandate upon a State, local or 
    tribal government, unless the Federal government provides the funds 
    necessary to pay the direct compliance costs incurred by those 
    governments, or EPA consults with those governments. If EPA complies by 
    consulting, E.O. 12875 requires EPA to provide to the OMB a description 
    of the extent of EPA's prior consultation with representatives of 
    affected State, local and tribal governments, the nature of their 
    concerns, copies of any written communications from the governments, 
    and a statement supporting the need to issue the regulation. In 
    addition, E.O. 12875 requires EPA to develop an effective process 
    permitting elected officials and other representatives of State, local 
    and tribal governments ``to provide meaningful and timely input in the 
    development of regulatory proposals containing significant unfunded 
    mandates.''
        Today's rule does not create a mandate on State, local, or tribal 
    governments. The rule does not impose any enforceable rules on any of 
    these entities. This action does not create any new requirements but 
    simply approves requirements that the State is already imposing. 
    Accordingly, the requirements of section 1(a) of E.O. 12875 do not 
    apply to this rule.
    
    C. Executive Order 13045
    
        Executive Order 13045, entitled ``Protection of Children from 
    Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
    1997),
    
    [[Page 35939]]
    
    applies to any rule that: (1) is determined to be ``economically 
    significant'' as defined under E.O. 12866, and (2) concerns an 
    environmental health or safety risk that the EPA has reason to believe 
    may have a disproportionate effect on children. If the regulatory 
    action meets both criteria, the Agency must evaluate the environmental 
    health or safety effects of the planned rule on children, and explain 
    why the planned regulation is preferable to other potentially effective 
    and reasonably feasible alternatives considered by the Agency.
        The EPA interprets E.O. 13045 as applying only to those regulatory 
    actions that are based on health or safety risks, such that the 
    analysis required under section 5-501 of the Order has the potential to 
    influence the regulation. This final rule is not subject to E.O. 13045 
    because it approves a State program.
    
    D. Executive Order 13084
    
        Under E.O. 13084, EPA may not issue a regulation that is not 
    required by statute, that significantly or uniquely affects the 
    communities of Indian tribal governments, and that imposes substantial 
    direct compliance costs on those communities, unless the Federal 
    Government provides the funds necessary to pay the direct compliance 
    costs incurred by the tribal governments, or EPA consults with those 
    governments. If EPA complies by consulting, E.O. 13084 requires EPA to 
    provide to the OMB, in a separately identified section of the preamble 
    to the rule, a description of the extent of EPA's prior consultation 
    with representatives of affected tribal governments, a summary of the 
    nature of their concerns, and a statement supporting the need to issue 
    the regulation. In addition, E.O. 13084 requires EPA to develop an 
    effective process permitting elected officials and other 
    representatives of Indian tribal governments ``to provide meaningful 
    and timely input in the development of regulatory policies on matters 
    that significantly or uniquely affect their communities.''
        Today's rule does not significantly or uniquely affect the 
    communities of Indian tribal governments. This action does not involve 
    or impose any new requirements that affect Indian tribes. Accordingly, 
    the requirements of section 3(b) of E.O. 13084 do not apply to this 
    rule.
    
    E. Regulatory Flexibility Act
    
        The Regulatory Flexibility Act (RFA), 5 U.S.C. 600 et seq., 
    generally requires an agency to conduct a regulatory flexibility 
    analysis of any rule subject to notice and comment rulemaking 
    requirements unless the agency certifies that the rule will not have a 
    significant economic impact on a substantial number of small entities. 
    Small entities include small businesses, small not-for-profit 
    enterprises, and small governmental jurisdictions. This final rule will 
    not have a significant impact on a substantial number of small entities 
    because SIP approvals under section 110 and subchapter I, part D of the 
    Act do not create any new requirements but simply approve requirements 
    that the State is already imposing. Therefore, because the Federal SIP 
    approval does not create any new requirements, I certify that this 
    action will not have a significant economic impact on a substantial 
    number of small entities. Moreover, due to the nature of the Federal-
    State relationship under the Act, preparation of a flexibility analysis 
    would constitute Federal inquiry into the economic reasonableness of 
    state action. The Act forbids EPA to base its actions concerning SIPs 
    on such grounds. See Union Electric Co., v. U.S. EPA, 427 U.S. 246, 
    255-66 (1976); 42 U.S.C. 7410(a)(2).
    
    F. Unfunded Mandates
    
        Under section 202 of the Unfunded Mandates Reform Act of 1995, 
    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 annual costs to State, 
    local, or tribal governments in the aggregate; or to 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.
        The EPA has determined that the approval action promulgated does 
    not include a Federal mandate that may result in estimated annual costs 
    of $100 million or more to either 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 
    requirements. Accordingly, no additional costs to State, local or 
    tribal governments, or to the private sector, result from this action.
    
    G. Submission to Congress and the Comptroller General
    
        The Congressional Review Act, 5 U.S.C. 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. The EPA will submit a report containing this rule and 
    other required information to the U.S. Senate, the U.S. House of 
    Representatives, and the Comptroller General of the United States prior 
    to publication of the rule in the Federal Register. A major rule can 
    not take effect until 60 days after it is published in the Federal 
    Register. This action is not a ``major'' rule as defined by 5 U.S.C. 
    804(2). This rule will be effective August 2, 1999.
    
    H. Petition for Judicial Review
    
        Under section 307(b)(1) of the Act, petitions for judicial review 
    of this action must be filed in the United States Court of Appeals for 
    the appropriate circuit by August 31, 1999. 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).
