    Approval and Promulgation of Maintenance Plan Revisions; Ohio
    
    AGENCY: Environmental Protection Agency.
    
    ACTION: Direct final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The United States Environmental Protection Agency (EPA) is 
    approving through ``direct final'' procedure, a March 13, 1998, request 
    from Ohio, for a State Implementation Plan (SIP) maintenance plan 
    revision for the Columbus ozone maintenance area (Franklin, Delaware 
    and Licking Counties). The maintenance plan revision establishes a new 
    maintenance year of 2010 for the area and a new transportation 
    conformity mobile source emissions budget for the year 2010. The 2010 
    emissions budget projections incorporate future emission reductions 
    from area and point sources. The newly established 2010 emissions 
    projections determine the area's safety margins for Oxides of Nitrogen 
    (NOX) and Volatile Organic Compounds (VOCs). Also being 
    approved is the State's request that a portion of the safety margins be 
    allocated to the area's 2010 mobile source emissions budget for 
    transportation conformity purposes. The area's safety margin is defined 
    as the difference between the attainment inventory level (the Columbus 
    area's attainment inventory year is 1990) of the total emissions and 
    the projected levels of the total emissions in the final year of the 
    maintenance plan (as established for Columbus in this rule to be 2010).
    
    DATES: This direct final rule is effective on September 8, 1998, unless 
    EPA receives relevant adverse or critical written comments by August 
    10, 1998. If adverse comment is received, the 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. Any parties interested 
    in commenting on this action should do so at this time. If no such 
    comments are received, the public is informed that

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        The Clean Air Act, in section 176(c), requires conformity of 
    activities to an implementation plan's purpose of attaining and 
    maintaining the National Ambient Air Quality Standards. On November 24, 
    1993, EPA promulgated a final rule establishing criteria and procedures 
    for determining conformity of transportation plans, programs and 
    projects funded or approved under Title 23 U.S.C. of the Federal 
    Transit Act. The State of Ohio finalized and adopted State 
    transportation conformity rules on August 1, 1995, the rules became 
    effective August 21, 1995, and Ohio submitted the rules as a SIP 
    revision request on August 17, 1995. The rules were approved by EPA on 
    July 15, 1996 (61 FR 24702).
        The transportation conformity rules require, among other things, a 
    comparison to the mobile source emissions budget established by a 
    control strategy SIP. A control strategy SIP is defined by the 
    conformity rules to be a maintenance plan, an attainment demonstration, 
    or a rate of progress plan. The Columbus area is an attainment area 
    with an approved maintenance plan. The EPA approval of the maintenance 
    plan established the mobile source emissions budget for transportation 
    conformity purposes.
        The emissions budget concept is explained in the preamble to the 
    November 24, 1993, transportation conformity rule (58 FR 62188). The 
    preamble also describes how to establish the mobile source emissions 
    budget in the SIP and how to revise the emissions budget. The State 
    transportation conformity rule at 3745-101-16 of the Ohio 
    Administrative Code allows the mobile source emissions budget to be 
    changed as long as the total level of emissions from all sources remain 
    below the milestone level. In the case of a maintenance plan the 
    milestone level is the attainment level established in the maintenance 
    plan.
        The maintenance plan is designed to provide for future growth while 
    still maintaining the ozone air quality standard. Growth in industries, 
    population and traffic is offset with reductions from cleaner cars and 
    other emissions reduction programs. Through the maintenance plan the 
    State and local agencies can manage and maintain air quality while 
    providing for growth.
    
    II. Evaluation of the State Submittal
    
        On March 13, 1998, Ohio submitted to EPA a SIP revision request for 
    the Columbus maintenance area. A public hearing on this proposal was 
    held on April 15, 1998. Documentation on the public hearing was 
    submitted on May 14, 1998 to complete the SIP revision request.
        In the submittal Ohio requested to establish a new maintenance year 
    of 2010, and new 2010 mobile source emissions budget for transportation 
    conformity for the Columbus, Ohio maintenance area.
    
    A. 2010 Budget Projections for Point and Area Sources
    
        The 2010 emissions projections for point and area sources were 
    developed by multiplying the individual 1990-2010 population growth 
    factors for each county in the area by the individual county 1990 
    baseline inventory. The population growth factors used in the point and 
    area source projections were derived from census population forecasts 
    from Ohio's Data Users Center. The projected emissions for each county 
    were then added together to arrive at the total projected emissions for 
    the point and area source sectors for the year 2010.
    
    B. NOX Point and Area Source Emission Changes for the 2010 
    Budget
    
        In developing the area's 2010 emissions projections for 
    NOX, the state took credit for reductions from the point and 
    area source sectors. Projected NOX reductions in point 
    sources were obtained from the shutdown of the Columbus Trashburning 
    Power Plant (3.04 tons/day NOX) and the installation of a 
    pure oxygen combustion system at Techniglass Inc. (1.43 tons/day 
    NOX). These point sources were included in Ohio's point 
    source emissions inventory that was submitted to EPA. The point source 
    NOX emission reductions were subtracted from the total 
    projected 2010 point source emission tonnage.
        Projected reductions in area sources were obtained by considering 
    the new federal ``Emission Standards for Locomotives and Locomotive 
    Engines; Final Rule'' (63 FR 18977; April 16, 1998) for new and 
    remanufactured diesel-powered locomotives. The federal locomotive 
    standards are expected to achieve a 41% reduction in NOX by 
    the year 2010. To be on the conservative side, Ohio calculated its' 
    projected NOX reductions from locomotives assuming 20% 
    NOX reductions by 2010 instead of 41% for the 2010 budget 
    (total reduction of 16.07 tons/day NOX from area sources). 
    The 16.07 tons/day NOX reduction was subtracted from the 
    total projected 2010 area source emission tonnage.
        The 2010 emission projections reflect the point and area source 
    reductions and are illustrated in Table 1.

    ----------------------------------------------------------------------------------------------------------------
    
    C. Safety Margin Allocations and 2010 Mobile Source Emissions Budget
    
        In the submittal Ohio requested to allocate to the mobile source 
    emissions budget part of the area's safety margin. The Columbus area's 
    safety margin is the difference between the 1990 attainment inventory 
    year and the 2010 projected emissions inventory (6.42 tons/day VOC 
    safety margin, and 13.88 tons/day NOX safety margin) as 
    shown in Table 1. The SIP revision requests the allocation of 6.27 
    tons/day VOC, and 9.91 tons/day NOX, into the area's mobile 
    source emissions budget from the safety margin. The 2010 mobile source 
    emissions budget showing the safety margin allocations are outlined in 
    Table 2. The mobile source emissions budget in Table 2 will be used for 
    transportation conformity purposes.

          Totals................................................       189.12       185.82       188.33      185.15 
    Remaining Safety Margin = 1990 total emissions -2010 total emissions = 3.97 tons/day NOX                        
    ----------------------------------------------------------------------------------------------------------------
    
        Table 2 illustrates that the requested portion of the safety 
    margins can be allocated to the 2010 mobile source budget and still 
    remain at or below the 1990 attainment level of total emissions for the 
    Columbus maintenance area. This allocation is allowed by the conformity 
    rule since the area would still be at or below the 1990 attainment 
    level for the total emissions.
    
    III. EPA Action
    
        After review of the SIP revision request, EPA finds that the 
    requested allocation of the safety margin for the Columbus area is 
    approvable since the approval of the new mobile source emissions 
    budgets for NOX and VOCs illustrates that the total 
    emissions for the area will be at or below the attainment year 
    inventory level as required by the transportation conformity 
    regulations. Therefore, EPA is approving the requested allocation of 
    the safety margin to the mobile source budget for the Columbus area.
        The EPA is publishing this action without prior proposal because 
    EPA views this as a noncontroversial revision 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 specified written adverse or critical comments be filed. This 
    action will become effective without further notice unless the Agency 
    receives relevant adverse written comments within 30 days from the date 
    of publication, as indicated above. Should the Agency receive such 
    comments, it will publish a final rule informing the public that this 
    action did not take effect. Any parties interested in commenting on 
    this action should do so at this time.
    
    IV. Administrative Requirements
    
    A. Executive Order 12866
    
        The Office of Management and Budget has exempted this regulatory 
    action from Executive Order 12866 review.
    
    B. Executive Order 13045
    
        The Final rule is not subject to Executive Order 13045, titled 
    ``Protection of Children from Environmental Health Risks and Safety 
    Risks,'' because it is not an ``economically significant'' action under 
    Executive Order 12866.
    
    C. Future Requests
    
        Nothing in this action should be construed as permitting, 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
    
    [[Page 37258]]
    
    factors and in relation to relevant statutory and regulatory 
    requirements.
    
    D. Regulatory Flexibility
    
        The Regulatory Flexibility Act (RFA) 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 Clean Air 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 
    Clean Air Act, preparation of a flexibility analysis would constitute 
    Federal inquiry into the economic reasonableness of state action. The 
    Clean Air Act forbids EPA to base its actions concerning SIPs on such 
    grounds. Union Electric Co., v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 
    42 U.S.C. 7410(a)(2).
    
    E. Unfunded Mandates
    
        Under section 202 of the Unfunded Mandates Reform Act of 1995, 
    signed into law on March 22, 1995, EPA must undertake various actions 
    in association with 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. 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 the private 
    sector, result from this action.
    
    F. Audit Privilege and Immunity Law
    
        Nothing in this action should be construed as making any 
    determination or expressing any position regarding Ohio's audit 
    privilege and immunity law (sections 3745.70--3745.73 of the Ohio 
    Revised Code ). EPA will be reviewing the effect of the Ohio audit 
    privilege and immunity law on various Ohio environmental programs, 
    including those under the Clean Air Act, and taking appropriate 
    action(s), if any, after thorough analysis and opportunity for Ohio to 
    state and explain its views and positions on the issues raised by the 
    law. The action taken herein does not express or imply any viewpoint on 
    the question of whether there are legal deficiencies in this or any 
    Ohio Clean Air Act program resulting from the effect of the audit 
    privilege and immunity law. As a consequence of the review process, the 
    regulations subject to the action taken herein may be disapproved, 
    federal approval for the Clean Air Act program under which they are 
    implemented may be withdrawn, or other appropriate action may be taken, 
    as necessary.
    
    G. Submission to Congress and the General Accounting Office
    
        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. 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. 804(2).
    
    H. Petitions 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 September 8, 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)).

    maintenance plan for the Columbus area. The revision consists of 
    establishing a new out year for the area's emissions budget. The new 
    out year emissions projections include reductions from point and area 
    sources; the revision also defines new safety margins according to the 
    difference between the areas 1990 baseline inventory and the out year 
    projection. Additionally, the revision consists of allocating a portion 
    of the Columbus area's safety margins to the transportation conformity 
    mobile source emissions budget. The mobile source budgets for 
    transportation conformity purposes for the Columbus area are now: 67.99 
    tons per day of volatile organic compound emissions for the year 2010 
    and 70.99 tons per day of oxides of nitrogen emissions for the year 
    2010.
