    SUMMARY: On November 2, 1994, the United States Environmental 
    Protection Agency (USEPA) proposed to approve a November 17, 1993, 
    request for a State Implementation Plan (SIP) revision, addressing the 
    Lake and Porter County ozone nonattainment area, submitted by the State 
    of Indiana for the purpose of offsetting growth in emissions from 
    growth in vehicle miles traveled (VMT) or number of vehicle trips, and 
    to attain reduction in motor vehicle emissions, in combination with 
    other emission 
    
    [[Page 38719]]
    reduction requirements, as necessary to comply with Reasonable Further 
    Progress (RFP) milestones and attainment requirements of the Clean Air 
    Act (Act). Public comments were solicited on the proposed SIP revision, 
    and on USEPA's proposed rulemaking action. The public comment period 
    ended on December 2, 1994, and one public comment letter was received. 
    This rulemaking action approves, in final, the VMT Offset SIP revision 
    request for Lake and Porter Counties, Indiana as requested by Indiana.
    
    EFFECTIVE DATE: This final rulemaking becomes effective on August 28, 
    1995.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        Section 182(d)(1)(A) of the Act, as amended in 1990 (Act), requires 
    States containing ozone nonattainment areas classified as ``severe'' 
    pursuant to section 181(a) of the Act to adopt transportation control 
    measures (TCMs) and transportation control strategies to offset any 
    growth in emissions from growth in VMT or number of vehicle trips, and 
    to attain reductions in motor vehicle emissions (in combination with 
    other emission reduction requirements) as necessary to comply with the 
    Act's RFP milestones and attainment requirements. The requirements for 
    establishing a VMT Offset program are discussed in the April 16, 1992, 
    General Preamble to Title I of the Act (57 FR 13498), in addition to 
    section 182(d)(1)(A) of the Act.
        The VMT Offset provision requires that States submit by November 
    15, 1992, specific enforceable TCMs and strategies to offset any growth 
    in emissions from growth in VMT or number of vehicle trips sufficient 
    to allow total area emissions to comply with the RFP and attainment 
    requirements of the Act.
        As described in the November 2, 1994, proposed rule (see 59 FR 
    54866, 54867), the USEPA has observed that these three elements (i.e., 
    offsetting growth in mobile source emissions, attainment of the RFP 
    reduction, and attainment of the ozone National Ambient Air Quality 
    Standards (NAAQS)) can be divided into three separate submissions that 
    could be submitted on different dates.
        Under this approach, the first element, the emissions offset 
    element, was due on November 15, 1992. The USEPA believes this element 
    is not necessarily dependent on the development of the other elements. 
    The State could submit the emissions growth offset element independent 
    of an analysis of that element's consistency with the periodic 
    reduction and attainment requirements of the Act. Emissions trends from 
    other sources need not be considered to show compliance with this 
    offset requirement. As submitting this element in isolation does not 
    implicate the timing problem of advancing deadlines for RFP and 
    attainment demonstrations, USEPA does not believe it is necessary to 
    extend the statutory deadline for submittal of the emissions growth 
    offset element.
        The second element, which requires the VMT Offset SIP to comply 
    with the 15 percent RFP requirement of the Act, was due on November 15, 
    1993, which is the same date on which the 15 percent RFP SIP itself was 
    due under section 182(b)(1) of the Act. The USEPA believes it is 
    reasonable to extend the deadline for this element to the date on which 
    the entire 15 percent SIP was due, as this allows States to develop the 
    comprehensive strategy to address the 15 percent reduction requirement 
    and assure that the TCM elements required under section 182(d)(1)(A) 
    are consistent with the remainder of the 15 percent demonstration. 
    Indeed, USEPA believes that only upon submittal of the broader 15 
    percent plan can a State have had the necessary opportunity to 
    coordinate its VMT strategy with its 15 percent plan.
        The third element, which requires the VMT Offset SIP to comply with 
    the post-1996 RFP and attainment requirements of the Act, was due on 
    November 15, 1994, the statutory deadline for those broader 
    submissions. The USEPA believes it is reasonable to extend the deadline 
    for this element to the date on which the post-1996 RFP and attainment 
    SIPs are due for the same reasons it is reasonable to extend the 
    deadline for the second element. First, it is arguably impossible for a 
    State to make the showing required by Section 182(d)(1)(A) for the 
    third element until the broader demonstrations have been developed by 
    the State. Moreover, allowing States to develop the comprehensive 
    strategy to address post-1996 RFP and attainment by providing a fuller 
    opportunity to assure that the TCM elements comply with the broader RFP 
    and attainment demonstrations, will result in a better program for 
    reducing emissions in the long term.
        On November 17, 1993, Indiana submitted to USEPA documentation to 
    fulfill the first and second elements of the VMT-Offset SIP. A public 
    hearing was held on December 14, 1993, and documentation on the public 
    hearing was submitted to complete the SIP revision request. Indiana 
    does not at this time anticipate the need for additional TCMs to meet 
    the attainment demonstration requirement but will submit any necessary 
    TCMs with the attainment demonstration SIP.
    
    II. Evaluation of the State Submittal
    
        Section 182(d)(1)(A) of the Act requires the State to offset any 
    growth in emissions from growth in VMT. As discussed in the General 
    Preamble, the purpose is to prevent a growth in motor vehicle emissions 
    from canceling out the emission reduction benefits of the federally 
    mandated programs in the Act. The USEPA interprets this provision to 
    require that sufficient measures be adopted so that projected motor 
    vehicle volatile organic compound (VOC) emissions will never be higher 
    during the ozone season in one year than during the ozone season in the 
    year before. When growth in VMT and vehicle trips would otherwise cause 
    a motor vehicle emissions upturn, this upturn must be prevented. The 
    emissions level at the point of upturn becomes a ceiling on motor 
    vehicle emissions. This requirement applies to projected emissions in 
    the years between the submission of the SIP revision and the attainment 
    deadline, and is above and beyond the separate requirements for the RFP 
    and the attainment demonstrations. The ceiling level is defined, 
    therefore, up to the point of upturn, as motor vehicle emissions that 
    would occur in the ozone season of that year, with VMT growth, if all 
    measures for that area in that year were implemented as required by the 
    Act. When this curve begins to turn up due to growth in VMT or vehicle 
    trips, the ceiling becomes a fixed value. The ceiling line would 
    include the effects of Federal measures such as new motor vehicle 
    standards, phase II RVP controls, and reformulated gasoline, as well as 
    the Act-mandated SIP requirements. 
    
    [[Page 38720]]
    
        The State of Indiana has demonstrated in its submittal of November 
    17, 1993, that the predicted growth in VMT in Lake and Porter Counties, 
    Indiana, is not expected to result in a growth in motor vehicle 
    emissions that will negate the effects of the reductions mandated by 
    the Act. Further, Indiana has projected motor vehicle emissions to the 
    year 2007 and, using the most current socioeconomic data, has not 
    predicted an upturn in motor vehicle emissions. In the event that the 
    projected socioeconomic data and associated VMT grow more rapidly than 
    currently predicted, Indiana is required by Section 182(c)(5) to track 
    actual VMT starting with 1996 and every three years thereafter to 
    demonstrate that the actual VMT is equal to or less than the projected 
    VMT. TCMs will be required to offset VMT that is above the projected 
    levels (section 182(c)(5)).
        The VMT offset submittal from Indiana dated November 17, 1993, 
    contains the final report ``TCMs to Offset Emissions from VMT Growth in 
    Northwestern Indiana.'' The report used the most current socioeconomic 
    data and the travel network model in conjunction with the MOBILE5a to 
    estimate mobile source emissions to the attainment year of 2007.
        This report also documents the progress Indiana has made in 
    evaluating TCMs to reduce growth in VMT and thus reduce emissions. 
    Indiana may choose to take credit for TCM emission reductions as part 
    of the post-1996 RFP requirement or to meet the attainment requirement. 
    Not only has Indiana evaluated the effectiveness and predicted impact 
    of a number of TCMs, but actual implementation of selected TCMs has 
    been ongoing. Several examples are cited in the proposed rule.
        These specific TCMs, however, are not a part of the current SIP 
    revision request and are not a required portion of this SIP revision. 
    Thus, Indiana is not currently taking credit for the emission 
    reductions from these TCM measures and the State is not bound to 
    implement or continue to implement any specific TCMs. These measures, 
    however, illustrate Indiana's work in evaluating and implementing TCMs 
    to meet the goals of the Act. Also, the TCMs may be used in subsequent 
    SIP submittals as necessary to meet the post 1996 RFP requirement or 
    the attainment requirement.
        Indiana submitted a 15 percent RFP SIP for northwest Indiana to the 
    USEPA in November 1993, but the submittal was found incomplete in a 
    letter dated January 25, 1994. The RFP SIP lacked enforceable 
    regulations and a public hearing. The public hearing was held on March 
    29, 1994.
        On June 26, 1995, Indiana submitted an updated 15 percent SIP which 
    contained all enforceable regulations. Indiana's submitted 15 percent 
    SIP was found complete by the USEPA in a letter dated July 7, 1995. The 
    submittal details the adopted enforceable regulations that have been 
    submitted to support the 15 percent RFP demonstration. The SIP 
    submission contains a menu of adopted emissions reductions measures 
    that the State believes will achieve the 15 percent reduction 
    requirement by November 15, 1996. Also, Indiana is moving forward with 
    implementation of the 15 percent measures including the enhanced 
    inspection and maintenance program. In the submission, Indiana does not 
    rely upon TCMs in order to satisfy the 15 percent reduction 
    requirement. Rather, the majority of the reduction would be obtained 
    from stationary source shutdowns and the enhanced inspection and 
    maintenance program. Indiana believes that TCMs will not be necessary 
    to attain the 15 percent reduction requirement.
        The attainment demonstration and post-1996 RFP plans, were 
    submitted on December 5, 1994, and became complete by operation of law 
    under 110(k)(1)(B) on June 5, 1995. Indiana is planning to use the 
    Phase I and II approach to submission of the attainment demonstration 
    and post-1996 RFP as described in the March 2, 1995, memorandum from 
    Mary Nichols. The USEPA is reserving action on the third element of the 
    VMT Offset SIP until such time as the phase I and II attainment 
    submittals are complete.
        Indiana has met the first and second elements of the VMT offset SIP 
    requirements of section 182(d)(1)(A). Regarding the first element, 
    Indiana has identified and evaluated TCMs to reduce VMT, and has shown 
    that VMT growth will not result in a growth of motor vehicle emissions 
    that will negate the effects of the reductions required under the Act 
    and that there will not be an upturn of motor vehicle emissions. 
    Regarding the second element, Indiana has submitted a complete 15 
    percent SIP that does not rely upon TCMs to make its proffered showing 
    that the 15 percent reduction will be achieved. Consequently, USEPA 
    does not believe it is necessary to delay taking action on this second 
    element of the VMT SIP, and that the Agency can at this point rely upon 
    Indiana's submitted 15 percent SIP to make a judgment that TCM's will 
    not be necessary to satisfy the second VMT SIP element. However, if in 
    evaluating the 15 percent SIP for approval it is determined that 
    Indiana would in fact have to implement TCMs to meet the 15 percent RFP 
    requirement, and a subsequent submission of a revised 15 percent SIP is 
    required, EPA would have to reevaluate its approval of the second 
    element of the VMT SIP.
        The third requirement is for Indiana to use TCMs as necessary to 
    attain the standard. This third requirement will be submitted with the 
    attainment demonstration SIP and will be addressed in a future Federal 
    Register notice.
    
    III. Public Comments
    
        On November 2, 1994, the USEPA proposed to approve the first and 
    second elements of the Indiana VMT Offset SIP and requested public 
    comment. The public comment period closed on December 2, 1994, and the 
    Natural Resources Defense Council (NRDC) submitted comments on December 
    2, 1994. The following summarizes NRDC's comments and USEPA's response 
    to these comments:
        Comment 1: The Act requires TCMs to offset emissions resulting from 
    all growth in VMT above 1990 levels, and USEPA is required by the Act 
    to ensure emission reductions despite an increase in VMT. The 
    legislative history states that ``[t]he baseline for determining 
    whether there has been a growth in emissions due to increased VMT is 
    the level of vehicle emissions that would occur if VMT held constant in 
    the area.'' See H.Rep. No. 101-490, Part I, 101st Cong., 2nd Sess. at 
    242, and S.Rep. No. 101-228, 101st Cong., 1st Sess. at 44.
        Response: As discussed in the General Preamble, USEPA believes that 
    section 182(d)(1)(A) of the Act requires the State to ``offset any 
    growth in emissions'' from growth in VMT but not, as suggested by the 
    comment, all emissions resulting from VMT growth (see 57 FR 13498, 
    13522-13523, April 16, 1992). The purpose is to prevent a growth in 
    motor vehicle emissions from canceling out the emission reduction 
    benefits of the federally mandated programs in the Act. The baseline 
    for emissions is the 1990 level of vehicle emissions and the subsequent 
    reductions in emission levels required to reach attainment. Thus, the 
    anticipated benefits from the mandated measures such as the Federal 
    motor vehicle pollution control program, lower reid vapor pressure, 
    enhanced inspection and maintenance and all other motor vehicle 
    emission control programs are included in the ceiling line calculation 
    used by Indiana in the VMT Offset SIP. Table 13 in the Indiana SIP 
    submittal demonstrates how motor vehicle emissions will decline 
    substantially from 136.63 tons per day (tpd) in 1990 to 25.04 tpd in 
    2007 and 
    
    [[Page 38721]]
    will not begin to turn up. Emission reductions are expected every year 
    through the year 2007.
        The ceiling line approach does not ``tolerate increases in traffic 
    of a magnitude that would wipe out the air quality gains'' as suggested 
    by the comment. In fact, the ceiling line level decreases from year to 
    year as the State implements various control measures and the 
    decreasing ceiling line prevents an upturn in mobile source emissions. 
    Dramatic increases in VMT that could wipe out the benefits of motor 
    vehicle emission reduction measures will not be allowed and will 
    trigger the implementation of TCMs. This prevents mere preservation of 
    the status quo, and ensures emissions reductions despite an increase in 
    VMT such that the rate of emissions decline is not slowed by increases 
    in VMT or number of trips. To prevent future growth changes from 
    adversely impacting emissions from motor vehicles, Indiana is required 
    by section 182(c)(5) to track actual VMT starting with 1996 and every 
    three years thereafter to demonstrate that the actual VMT is equal to 
    or less than the projected VMT. TCMs will be required to offset VMT 
    that is above the projected levels (section 182(c)(5)).
        Under the commenter's approach to section 182(d)(1)(A), Indiana 
    would have to offset VMT growth even while vehicle emissions are 
    declining. Although the statutory language could be read to require 
    offsetting any VMT growth, EPA believes that the language can also be 
    read so that only actual emissions increases resulting from VMT growth 
    need to be offset. The statute by its own terms requires offsetting of 
    ``any growth in emissions from growth in VMT.'' It is reasonable to 
    interpret this language as requiring that VMT growth must be offset 
    only where such growth results in emissions increases from the motor 
    vehicle fleet in the area.
        While it is true that the language of the legislative history 
    appears to support the commenter's interpretation of the statutory 
    language, such an interpretation would have drastic implications for 
    Indiana if the State were forced to ignore the beneficial impacts of 
    all vehicle tailpipe and alternative fuel controls. Although the 
    original authors of the provision and the legislative history may in 
    fact have intended this result, EPA does not believe that the Congress 
    as a whole, or even the full House of Representatives, believed at the 
    time it voted to pass the 1990 Amendments to the Act that the words of 
    this provision would impose such severe restrictions.
        Given the susceptibility of the statutory language to these two 
    alterative interpretations, EPA believes it is the Agency's role in 
    administering the statute to take the interpretation most reasonable in 
    light of the practical implications of such interpretation and the 
    purposes and intent of the statutory scheme as a whole. In the context 
    of the intricate planning requirements Congress established in title I 
    to bring areas towards attainment of the ozone NAAQS, and in light of 
    the absence of any discussion of this aspect of the VMT offset 
    provision by the Congress as a whole (either in floor debate or in the 
    Conference Report), EPA concludes that the appropriate interpretation 
    of section 182(d)(1)(A) requires offsetting VMT growth only when such 
    growth would result in actual emissions increases.
        Comment 2: Section 182(d)(1)(A) of the Act requires that emissions 
    of oxides of nitrogen (NOX) as well as VOCs resulting from VMT 
    growth must be offset.
        Response: USEPA disagrees with the commenter's interpretation that 
    section 182(d)(1)(A) requires NOx emissions from VMT growth to be 
    offset. While that section provides that ``any growth in emissions'' 
    from growth in VMT must be offset, USEPA believes that Congress clearly 
    intended that the offset requirement be limited to VOC emissions. 
    First, section 182(d)(1)(A)'s requirement that a State's VMT TCMs 
    comply with the ``periodic emissions reduction requirements'' of 
    sections 182(b) and (c) the Act indicates that the VMT offset SIP 
    requirement is VOC-specific. Section 182(c)(2)(B), which requires 
    reasonable further progress demonstrations for serious ozone 
    nonattainment areas, provides that such demonstrations will result in 
    VOC emissions reductions; thus, the only ``periodic emissions reduction 
    requirement'' of section 182(c)(2)(B) is VOC-specific. In fact, it is 
    only in section 182(c)(2)(C)--a provision not referenced in section 
    182(d)(1)(A)--that Congress provided States the authority to submit 
    demonstrations providing for reductions of emissions of VOCs and 
    NOX in lieu of the SIP otherwise required by section 182(c)(2)(B).
        Moreover, the 15 percent periodic reduction requirement of section 
    182(b)(1)(A)(i) applies only to VOC emissions, while only the separate 
    ``annual'' reduction requirement applies to both VOC and NOX 
    emissions. USEPA believes that Congress did not intend the terms 
    ``periodic emissions reductions'' and ``annual emissions reductions'' 
    to be synonymous, and that the former does not include the latter. In 
    section 176(c)(3)(A)(iii) of the Act, Congress required that conformity 
    SIPs ``contribute to annual emissions reductions'' consistent with 
    section 182(b)(1) (and thus achieve NOX emissions reductions), but 
    does not refer to the 15 percent periodic reduction requirement. 
    Conversely, section 182(d)(1)(A) refers to the periodic emissions 
    reduction requirements of the Act, but does not refer to annual 
    emissions reduction requirements that require NOX reductions. 
    Consequently, USEPA interprets the requirement that VMT SIPs comply 
    with periodic emissions reduction requirements of the Act to mean that 
    only VOC emissions are subject to section 182(d)(1)(A) in severe ozone 
    nonattainment areas.
        Finally, USEPA notes that where Congress intended section 182 ozone 
    SIP requirements to apply to NOX as well as VOC emissions, it 
    specifically extended applicability to NOX. Thus, references to 
    ozone or emissions in general in section 182 do not on their own 
    implicate NOX. For example, in section 182(a)(2)(C), the Act 
    requires States to require preconstruction permits for new or modified 
    stationary sources ``with respect to ozone''; Congress clearly did not 
    believe this reference to ozone alone was sufficient to subject 
    NOX emissions to the permitting requirement, since it was 
    necessary to enact section 182(f)(1) of the Act, which specifically 
    extends the permitting requirement to major stationary sources of 
    NOX. Since section 182(d)(1)(A) does not specifically identify 
    NOX emissions requirements in addition to the VOC emissions 
    requirements identified in the provision, USEPA does not believe States 
    are required to offset NOX emissions from VMT growth in their 
    section 182(d)(1)(A) SIPs.
    
    IV. Final Rulemaking Action
    
        Based on the State's submittal request and in consideration of the 
    public comments received in response to the proposed rule, USEPA is 
    approving the SIP revision submitted by the State of Indiana as 
    satisfying the first two of the three VMT offset plan requirements.
        The Office of Management and Budget has exempted this regulatory 
    action from Executive Order 12866 review.
        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 any 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., USEPA 
    must prepare a regulatory flexibility analysis assessing the impact of 
    any proposed or 
    
    [[Page 38722]]
    final rule on small entities. 5 U.S.C. 603 and 604. Alternatively, 
    USEPA 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 enterprises, and government entities 
    with jurisdiction over populations of less than 50,000.
        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 impose any new requirements, I certify that it does 
    not have a significant impact on small entities affected. Moreover, due 
    to the nature of the Federal-state relationship under the Act, 
    preparation of a regulatory flexibility analysis would constitute 
    Federal inquiry into the economic reasonableness of state action. The 
    Act forbids USEPA to base its actions concerning SIPs on such grounds. 
    See Union Electric Co. v. U.S. E.P.A. , 427 U.S. 246, 256-66 (S. Ct. 
    1976); 42 U.S.C. 7410(a)(2).
        Under Section 202 of the Unfunded Mandates Reform Act of 1995 
    (``Unfunded Mandates Act''), signed into law on March 22, 1995, the 
    USEPA must prepare a budgetary impact statement to accompany any 
    proposed or final rule that includes a Federal mandate that may result 
    in estimated costs to State, local, or tribal governments in the 
    aggregate; or to the private sector, of $100 million or more. Under 
    Section 205, the USEPA 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 the USEPA 
    to establish a plan for informing and advising any small governments 
    that may be significantly or uniquely impacted by the rule.
        The USEPA has determined that the approval action promulgated today 
    does not include a Federal mandate that may result in estimated 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 Federal requirements. Accordingly, no 
    additional costs to State, local, or tribal governments, or the private 
    sector, result from this action.
        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 26, 1995. 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)).

        (h) On November 17, 1993, Indiana submitted two of three elements 
    required by section 182(d)(1)(A) of the Clean Air Amendments of 1990 to 
    be incorporated as part of the vehicle miles traveled (VMT) State 
    Implementation Plan intended to offset any growth in emissions from a 
    growth in vehicle miles traveled. These elements are the offsetting of 
    growth in emissions attributable to growth in VMT which was due 
    November 15, 1992, and, any transportation control measures (TCMs) 
    required as part of Indiana's 15 percent reasonable further progress 
    (RFP) plan which was due November 15, 1993. Indiana satisfied the first 
    requirement by projecting emissions from mobile sources and 
    demonstrating that no increase in emissions would take place. Indiana 
    satisfied the second requirement by determining that no TCMs were 
    required as part of Indiana's 15 percent RFP plan.
