NOTICE: RULES

ACTION: Air quality implementation plans; approval and promulgation; various States:

DOCUMENT ACTION: Direct final rule.

SUBJECT CATEGORY: Approval and Promulgation of Implementation Plans Indiana: Revised Mobile Source Inventories and Motor Vehicle Emissions Budgets for 2005 and 2007 Using MOBILE6

DATES: This ``direct final'' rule is effective on October 12, 2004, unless EPA receives adverse written comments by September 27, 2004. If adverse comment is received, EPA will publish a timely withdrawal of the rule in the Federal Register and inform the public that the rule will not take effect.

DOCUMENT SUMMARY: EPA is approving Indiana's August 6, 2004, submittal of revised mobile emission inventories and 2005 and 2007 motor vehicle emissions budgets (MVEBs) which have been developed using MOBILE6, an updated model for calculating mobile emissions of ozone precursors. These inventories and associated motor vehicle emissions budgets are part of the 1hour ozone attainment plan approved for the Northwest Indiana area. The Northwest Indiana area consists of Lake and Porter Counties in Indiana. The State's submittal meets a commitment by the State of Indiana to revise and resubmit the MVEBs using MOBILE6 methods within two years following EPA's release of MOBILE6, provided that transportation conformity is not determined without adequate MOBILE6 based MVEBs during the second year. The lack of approved motor vehicle emissions budgets has resulted in an administrative freeze on transportation conformity in this area. The approval of these budgets will allow transportation conformity determinations to be made in Northwest Indiana.

II. What Is the Background for This Action?

In November of 1999, EPA issued two memoranda \1\ to articulate its policy regarding states that incorporated MOBILE5based interim Tier 2 standard \2\ benefits into their State Implementation Plans (SIPs) and MVEBs. Although these memoranda primarily targeted certain serious and severe ozone nonattainment areas, EPA has implemented this policy in all other areas that have made use of federal Tier 2 benefits in air quality plans from EPA's April 2000 MOBILE5 guidance, ``MOBILE5 Information Sheet 8: Tier 2 Benefits Using MOBILE5.'' All states whose attainment demonstrations or maintenance plans include interim MOBILE5based estimates of the Tier 2 standards were required to make a commitment to revise and resubmit their MVEBs within either one or two years of the final release of MOBILE6 in order to gain SIP approval.
\1\ Memoranda, ``Guidance on Motor Vehicle Emissions Budgets in 1Hour Ozone Attainment Demonstrations,'' issued November 3, 1999, and ``1Hour Ozone Attainment Demonstrations and Tier2/Sulfur Rulemaking,'' issued November 8, 1999. Copies of these memoranda are on EPA's Web site at http://www.epa.gov/otaq/transp/traqconf.htm. \2\ The final rule on Tier 2 Motor Vehicle Emissions Standards and Gasoline Sulfur Control Requirements (``Tier 2 standards'') for passenger cars, light trucks, and larger passenger vehicles was published on February 10, 2000 (65 FR 6698).

EPA officially released the MOBILE6 motor vehicle emissions factor model on January 29, 2002 (67 FR 4254). Thus, the effective date of that Federal Register action constituted the start of the twoyear time period in which Indiana was required to revise the maintenance plan SIPs using the MOBILE6 model.

MOBILE5b, as released, did not allow the user to estimate the emission reduction credits for the Tier 2/Low Sulfur rule. This situation existed since the Tier 2 rule was promulgated after the release of MOBILE5b. Therefore, in order to allow areas that wanted to claim emission reduction credit for the Tier 2/Low Sulfur rule to estimate the benefits, EPA provided a method to estimate those reductions. This MOBILE5b approximation methodology represented the information available for use in onroad mobile source modeling at that time when MOBILE5b was the approved model. EPA recognized these approximations could change as more data are analyzed and incorporated into the next version of the MOBILE model, MOBILE6. EPA required areas that used the MOBILE5b approximation method to resubmit MVEBs recalculated with MOBILE6. Specifically, EPA established a policy that MVEBs would not be approved as being adequate for purposes of conformity unless the SIP also included an enforceable commitment to revise and resubmit the MVEBs using MOBILE6 methods within one year after the EPA released MOBILE6 or, alternatively, within two years following the release of MOBILE6, provided that transportation conformity is not determined in the area without adequate MOBILE6based MVEBs during the second year. Based on this policy, EPA required Indiana to update the MVEBs in the 1hour ozone attainment
demonstration for Northwest Indiana within two years after the release of MOBILE6. In addition, any new conformity analysis in the area cannot be found to conform during the second year until MVEBs based on MOBILE6 calculations are found adequate (November 13, 2001, 66 FR 56944). For a more detailed explanation of EPA's rationale for this policy, please refer to the January 18, 2002, ``Policy Guidance on the Use of MOBILE6 for SIP Development and Transportation Conformity'' (http://www.epa.gov/otaq/models/mobile6/m6policy.pdf ).

III. What Action Is EPA Taking Today?

EPA is approving revisions to the Indiana SIP submitted by the Indiana Department of Environmental Management (IDEM). The SIP revision request was originally submitted on July 2, 2004, with a request to parallel process the draft revision. The state public comment period ended on July 30, 2004, and IDEM submitted the final SIP revision request on August 6, 2004. The State's revisions update the MVEBs for the years 2005 and 2007 and also update the projected mobile source emissions (upon which the MVEBs are based) using MOBILE6 for Lake and Porter Counties in Indiana, which are part of the Chicago 1hour severe ozone nonattainment area. These revisions meet the requirements established in the final approval of the attainment demonstration (November 13, 2001, 66 FR 56944). These revisions also meet the criteria in the January 18, 2002, Guidance document, ``Policy Guidance on the Use of MOBILE6 for SIP Development and Transportation Conformity.''
IV. What Changes Were Made to the Northwest Indiana 1Hour Ozone MVEBs?

Indiana revised MVEBs and mobile source emissions using MOBILE6.2, the current version of MOBILE6, and using the latest population and transportation model updates. The revised 2005 MVEB for the Lake and Porter County area is 15.18 tons per summer day (tpd) for Volatile Organic Compounds (VOC). The revised 2007 MVEBs for the Lake and Porter County area are 12.37 tpd VOC and 63.33 tpd for Nitrogen Oxides (NOX) (Please refer to the table below for details.)

Table 1 below summarizes the revised motor vehicle emissions inventories for VOC for the Lake and Porter County area in pounds (lbs) per summer day. These revised inventories were developed using the latest planning assumptions, including vehicle registration data, vehicle miles traveled (VMT), speeds, fleet mix, and SIP emission control measures. These inventories meet the Rate of Progress (ROP) targets for the Lake and Porter County area. Indiana was required to reduce VOC emissions by nine percent between 2002 to 2005. In the original ROP Plan, Indiana had additional emission reductions above and beyond what was required. The approved ROP Plan had an extra reduction of 7,852 lbs. per summer day. The extra creditable reductions were primarily from the shutdown of certain steel operations. The Indiana ROP Plan was approved as part of the attainment demonstration approval on November 13, 2001, (66 FR 56944).

Total......................... ......................... 529,519 211,191 204,238

The Indiana submittal also addresses the 6% ROP emission reduction needed for the years 2005 to 2007. Again, Indiana had additional VOC emissions in the originally approved ROP Plan. These additional emissions are above and beyond the 3% contingency requirements which were also met and approved. Indiana has used the additional, excess emissions reductions by allocating them to the mobile source sector for the emissions budgets. By using the excess emission reductions, Indiana no longer has additional excess ROP emissions in the approved ROP Plan.

IDEM and EPA also reviewed planning assumptions for the point, area, and nonroad source categories to ensure there have been no major changes since approval of the attainment demonstration. The emissions for point, area, and nonroad source categories are shown in Table 1, in addition to the mobile source emissions.

EPA has articulated its policy regarding the use of MOBILE6 in SIP development in its ``Policy Guidance on the Use of MOBILE6 for SIP Development and Transportation Conformity'' \3\ and ``Clarification of Policy Guidance for MOBILE6 in Midcourse Review Areas.'' \4\ \3\ Memorandum, ``Policy Guidance on the Use of MOBILE6 for SIP development and Transportation Conformity,'' issued January 18, 2002. A copy of this memorandum can be found on EPA's Web site at http://www.epa.gov/otaq/transp/traqconf.htm. \4\ Memorandum, ``Clarification of Policy Guidance for MOBILE6 SIPs in Midcourse Review Areas,'' issued February 12, 2003. A copy of this memorandum can be found on EPA's Web site at http://www.epa.gov/otaq/transp/traqconf.htm .

Consistent with this policy guidance, Indiana's August 6, 2004, submittal includes urban airshed modeling results to show that its 1 Hour Ozone Attainment Demonstration Plan continues to demonstrate attainment using revised MOBILE6 inventories for the Northwest Indiana area and the entire Lake Michigan area. The State's methodology for the urban airshed modeling consisted of modeling the critical episode from 1995 with the increased emissions in Northwest Indiana to determine if attainment will still be predicted by the established 2007 attainment date. The emissions were increased by a 5% margin to assure that, even with extra emissions, the area would demonstrate attainment. The modeling showed that the regional strategy met the three benchmarks in EPA's 1hour attainment test (``Guidance on Use of Modeled Results to Demonstrate Attainment of the Ozone NAAQS'', June 1996). The benchmarks set limits on the number of modeled exceedance days. All three of the benchmarks were met by the modeling that considered increased emissions.

Indiana's August 6, 2004 submittal satisfies the conditions outlined in EPA's MOBILE6 Policy guidance, and demonstrates that the new levels of motor vehicle emissions calculated using MOBILE6 continue to support achievement of the projected attainment of the 1Hour Ozone NAAQS by the attainment date of November 15, 2007, for the Northwest Indiana area.

V. What Is Transportation Conformity?

Transportation conformity means that the level of emissions from the transportation sector (i.e., cars, trucks and buses) must be consistent with the requirements in the SIP to attain and maintain the National Ambient Air Quality Standard (NAAQS). The Clean Air Act, in section 176(c), requires conformity of transportation plans, programs and projects to a SIP's purpose of attaining and maintaining the NAAQS. On November 24, 1993, EPA published a final rule establishing criteria and procedures for determining if transportation plans, programs and projects funded or approved under Title 23 United States Code or the Federal Transit Act conform to the SIP. EPA revised the Transportation Conformity Rule on August 7, 1995 (60 FR 40098), November 14, 1995 (60 FR 57179), and August 15, 1997 (62 FR 43780), and codified the revisions under 40 CFR part 51, subpart T and 40 CFR part 93, subpart AConformity to State or Federal Implementation Plans of
Transportation Plans, Programs, and Projects Developed, Funded or Approved Under Title 23 United States Code or the Federal Transit Laws (62 FR 43780). The transportation conformity rules require the comparison of an ozone nonattainment area to the actual projected emissions from cars, trucks and buses on the highway network, to the MVEB established by the SIP. The Northwest Indiana area has an approved attainment demonstration. EPA's approval of the attainment demonstration on November 13, 2001, (66 FR 56944) established interim MVEBs for transportation conformity purposes. These SIP revisions revise the MVEBs and reestablish the MVEBs for transportation conformity purposes.

VI. What Is a MVEB?

A MVEB is the projected level of controlled emissions from the transportation sector (mobile sources) that is estimated in the SIP. The SIP controls emissions through regulations, for example, on fuels and exhaust levels for cars. The MVEB concept is further explained in the preamble to the November 24, 1993, transportation conformity rule (58 FR 62188). The preamble also describes how to establish the MVEB in the SIP and revise the MVEB. The transportation conformity rule allows the MVEB to be changed as long as the total level of emissions from all sources remains below the attainment level of emissions.
VII. How Does This Action Change Implementation of Transportation Conformity for the Northwest Indiana Area?

In today's action, EPA is approving revisions to the 2005 and 2007 MVEBs for the Indiana portion of the Chicago 1hour ozone nonattainment area. The revised 2005 MVEB for the Northwest Indiana area is 15.18 tpd for VOC. The revised 2007 MVEBs for the Lake and Porter County area are 12.37 tpd for VOC and 63.33 tpd for NOX.

As a result of these findings, the Northwest Indiana area must use the revised 2005 and 2007 MVEBs for future conformity determinations effective on the date of this action. EPA's approval of the MVEBs removes the administrative freeze on transportation conformity on the area and allows the area to demonstrate conformity.

VIII. What Is the Action?

EPA is approving Indiana's SIP revisions because they meet all of the requirements of section 110 of the Clean Air Act, as interpreted by EPA policy and guidance. Additionally, these SIP revisions meet the applicable requirements of the Transportation Conformity Rule. [[Page 52431]]

IX. Did Indiana Hold a Public Hearing?

Indiana held a public hearing on July 28, 2004 in Merrillville, Indiana. The public comment period extended until July 30, 2004. No comments were received during the comment period including at the public hearing.

X. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a ``significant regulatory action'' and therefore is not subject to review by the Office of Management and Budget.
Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

For this reason, this action is also not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). Regulatory Flexibility Act

This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.).

Unfunded Mandates Reform Act

Because this rule approves preexisting requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 1044).
Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

Executive Order 13132: Federalism

This action also does not have Federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act.
Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

This rule also is not subject to Executive Order 13045 ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because it is not economically significant. National Technology Transfer Advancement Act

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply.

Paperwork Reduction Act

This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

Congressional Review Act

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. A major rule cannot 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).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 25, 2004. 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).)
