Transportation Conformity Rule: MOVES Regional Grace Period


AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to extend the grace period before the MOtor

Vehicle Emission Simulator model (currently MOVES2010a) is required for regional emissions analyses for transportation conformity determinations (``regional conformity analyses''). This proposal would provide an additional year to the previously established two-year conformity grace period, so that MOVES2010a would not be required for regional conformity analyses until March 2, 2013. This proposal would not affect EPA's previous approval of the use of MOVES in official state air quality implementation plan (SIP) submissions or the existing grace period before MOVES2010a is required for carbon monoxide and particulate matter hot-spot analyses for project-level conformity determinations.

DATES: Written comments on this proposal must be received on or before

November 14, 2011.

  7. Background

    1. What is transportation conformity?

      Transportation conformity is required under Clean Air Act (CAA) section 176(c) (42 U.S.C. 7506(c)) to ensure that transportation plans, transportation improvement programs (TIPs), and federally supported highway and transit projects are consistent with the purpose of the

      SIP. Conformity to the purpose of the SIP means that transportation activities will not cause or contribute to new air quality violations, worsen existing violations, or delay timely attainment of the relevant national ambient air quality standard (NAAQS) or required interim milestones.

      Transportation conformity (hereafter, ``conformity'') applies to areas that are designated nonattainment, and those areas redesignated to attainment after 1990 (``maintenance areas'') for transportation- related criteria pollutants: Ozone, particulate matter

      (PM2.5and PM10) \1\, carbon monoxide (CO), and nitrogen dioxide (NO2). EPA's conformity rule (40 CFR Parts 51 and 93) establishes the criteria and procedures for determining whether transportation activities conform to the SIP. EPA first promulgated the conformity rule on November 24, 1993 (58 FR 62188) and subsequently published several other amendments. The Department of

      Transportation (DOT) is EPA's federal partner in implementing the conformity regulation. EPA has coordinated with DOT, and they concur with this proposal.

      \1\ 40 CFR 93.102(b)(1) defines PM2.5and

      PM10as particles with an aerodynamic diameter less than or equal to a nominal 2.5 and 10 micrometers, respectively.

    2. What is MOVES2010a, and how has it been implemented to date?

      The MOtor Vehicle Emission Simulator model (MOVES) is EPA's state- of-the-art model for estimating emissions from highway vehicles, based on analyses of millions of emission test results and considerable advances in the Agency's understanding of vehicle emissions. MOVES is currently EPA's official emissions model for state and local agencies to estimate volatile organic compounds (VOCs), nitrogen oxides

      (NOX), PM, CO, and other precursors from cars, trucks, buses, and motorcycles for SIP purposes and conformity determinations outside of California. MOVES' database-centered design allows EPA to update emissions data more frequently and allows users much greater flexibility in organizing input and output data.

      MOVES2010a is the latest official version of MOVES that EPA has approved for SIP and conformity purposes. EPA originally announced the release of MOVES2010 in the Federal Register on March 2, 2010 (75 FR 9411) and subsequently released MOVES2010a on September 8, 2010.

      MOVES2010a includes minor revisions that enhance model performance and did not significantly affect criteria pollutant emissions results.

      Since these are minor revisions to MOVES2010, MOVES2010a is not considered a ``new model'' under section 93.111 of the conformity rule, as described further below.

      MOVES2010a is a significant improvement over the previous emissions model, MOBILE6.2,\2\ in terms of quality of results and overall functionality. It incorporates the latest emissions data, more sophisticated calculation algorithms, increased user flexibility, new software design, and significant new capabilities. While these changes improve the quality of on-road mobile source inventories, the overall degree of change in the model's function also adds to the start-up time required for the transition from MOBILE6.2 to MOVES2010a.

      \2\ EPA announced the release of MOBILE6.2 in 2004 (69 FR 28830).

      EPA developed MOVES as a completely new model. Whereas MOBILE6.2 was written in FORTRAN and used simple text files for data input and output, MOVES2010a is written in JAVA and uses a relational database structure in MYSQL to handle input and output as data tables. These changes make MOVES more flexible, and the analysis of new data incorporated within MOVES will enhance state and local agency understanding of how on-road mobile sources contribute to emissions inventories and the relative effectiveness of various control strategies. However, this new model framework has created a significant learning curve for state and local agency staff that are required to use MOVES.\3\

      \3\ Some states also purchased computers with additional capacity and features for running MOVES.

      In addition to the challenges of learning new software, state and local agencies also have to make substantial changes in the processes they have developed to create model input and apply model output. While there were incremental changes between each previous version of the

      MOBILE model, the basic input and output structure of that model was essentially unchanged since the early 1980s. Over time, state and local agencies developed their own methods for incorporating local inputs in

      MOBILE format and for post-processing MOBILE results for inventory development and air quality modeling. To help state and local agencies with this part of the current transition, EPA created a number of tools that take input data formatted for MOBILE6.2 and convert that data for use in MOVES2010a.

      EPA anticipated many of these challenges when it released MOVES. In order to assist in this model transition, EPA and DOT have already provided hands-on MOVES training in many states.\4\ Additional MOVES training for regional inventories has been requested, and will continue to be offered for the foreseeable future. EPA continues to provide other technical assistance to state and local agencies via on-going conference calls with user groups, e-mail and phone support, a frequently asked questions web page, and web-based presentations. All of these efforts are helping state and local agencies make the transition to MOVES2010a, and many agencies are making significant progress in applying the model for official purposes. However, other state and local agencies are still developing the technical capacity to use MOVES2010a, and need more time to transition to the model and then evaluate whether SIPs and their motor vehicle emissions budgets, or transportation plans and TIPs, should be

      Page 63578

      revised for future conformity determinations.

      \4\ To date, EPA and DOT staff have provided a 2-day hands-on

      MOVES course for regional emissions inventories (including regional conformity analyses) at over 30 locations around the country.

    3. Why is EPA conducting this rulemaking?

      If finalized, today's action would provide additional time that may be critical for nonattainment and maintenance areas to learn and apply

      MOVES2010a for regional conformity analyses.\5\ EPA has been contacted by several state and local transportation and air quality agencies and associations that are concerned that there has not been sufficient transition time for using MOVES2010a in regional conformity analyses.

      These concerns revolve around the time needed to build technical capacity for using MOVES2010a as well as completing necessary SIP and/ or transportation plan/TIP changes to assure conformity in the future.

      Further details on today's action are provided below.

      \5\ MPOs conduct regional conformity analyses to demonstrate that transportation plans and TIPs are consistent with the air quality purposes of the SIP. Regional conformity analyses are also conducted in ``isolated rural nonattainment and maintenance areas''

      (defined by 40 CFR 93.101).

      Today's proposal would not affect EPA's previous approval of

      MOVES2010a for official SIP submissions developed outside of

      California.\6\ Today's rulemaking would also not affect the existing grace period before MOVES2010a is required for PM2.5,

      PM10, and CO hot-spot analyses for project-level conformity determinations (75 FR 79370). EPA coordinated closely with DOT in developing today's action, and DOT concurs on this proposed rule.

      \6\ MOVES is not approved for use in California. EPA approved and announced the latest version of California's EMFAC model

      (EMFAC2007) for SIP development and regional conformity analyses in that state on January 18, 2008 (73 FR 3464).

  8. Extension of MOVES2010a Regional Conformity Grace Period

    1. Background

      CAA section 176(c)(1) states that ``* * * [t]he determination of conformity shall be based on the most recent estimates of emissions, and such estimates shall be determined from the most recent population, employment, travel, and congestion estimates * * *.'' To meet this requirement, section 93.111 of the conformity rule requires that conformity determinations be based on the latest motor vehicle emissions model approved by EPA. When EPA approves a new emissions model, EPA consults with DOT to establish a grace period before the model is required for conformity analyses (40 CFR 93.111(b)). EPA must consider many factors when establishing a grace period for conformity determinations (40 CFR 93.111(b)(2)). The length of the grace period will depend on the degree of change in the model and the scope of re- planning likely to be necessary for MPOs in order to assure conformity.

      The conformity rule provides for a grace period for new emissions models of between three and 24 months (40 CFR 93.111(b)(1)).

      In the preamble to the original 1993 conformity rule, EPA articulated its intentions for establishing the length of conformity grace period for a new emissions model (58 FR 62211):

      ``EPA and DOT will consider extending the grace period if the effects of the new emissions model are so significant that previous

      SIP demonstrations of what emission levels are consistent with attainment would be substantially affected. In such cases, states should have an opportunity to revise their SIPs before MPOs must use the model's new emissions factors. EPA encourages all agencies to inform EPA of the impacts of new emissions models in their area, and

      EPA may pause to seek such input before determining the length of the grace period.''

      Section 93.111 conformity requirements have not changed since 1993, and have been implemented successfully for many previous model transitions.

      On March 2, 2010, EPA announced the official release of MOVES2010 and established a two-year grace period before this model was required for new regional conformity analyses (75 FR 9411). Although the original grace period was established for MOVES2010, EPA clarified in

      September 2010 that the same grace period for regional conformity analyses also applies to MOVES2010a.\7\ EPA based its decision to establish a two-year conformity grace period on the factors under section 93.111(b)(2), and advised areas to use the interagency consultation process to examine the impact of using MOVES in their future regional conformity analyses.

      \7\ See ``EPA Releases MOVES2010a Mobile Source Emissions Model

      Update: Questions and Answers'' (EPA-420-F-10-050, August 2010) at:

      Without further EPA action, MOVES2010a would be required for regional conformity analyses that begin after March 2, 2012. As discussed further in today's action, the special circumstances of the transition from MOBILE to MOVES2010a require a reevaluation of the length of this conformity grace period.

    2. Description of Proposed Rule

      In today's action, EPA is proposing to provide an additional year before MOVES2010a is required for regional conformity analyses. If finalized, MOVES2010a would be required for new regional conformity analyses that begin after March 2, 2013. State and local agencies outside California would use MOVES2010a for regional conformity analyses earlier than March 2, 2013, if desired, and would be required to do so under limited circumstances such as after MOVES2010a SIP motor vehicle emissions budgets have been found adequate or approved for conformity purposes.

      Due to the unique circumstances presented by the transition from

      MOBILE6.2 to MOVES2010a, EPA is proposing to add a new paragraph (b)(3) to section 93.111 of the conformity rule. This provision would only apply to MOVES2010a and any future minor revisions to this model that

      EPA releases before March 2, 2013. Such minor revisions would not start a new grace period for regional conformity analyses and could include performance enhancements that reduce MOVES run time or model improvements to reduce errors in operating the model. Any major model updates, such as an update that significantly changes MOVES results for criteria pollutant emissions, would be evaluated separately as a ``new model'' under conformity rule section 93.111, pursuant to previously established requirements.

      Before the end of the extended conformity grace period (March 2, 2013), areas would use the interagency consultation process to examine how MOVES2010a would impact their future MPO transportation plan/TIP conformity determinations. Isolated rural areas would also consider the impact of using MOVES2010a on future regional conformity analyses. If finalized, agencies should carefully consider whether the SIP and its motor vehicle emissions budgets should be revised with MOVES2010a or if transportation plans and TIPs should be revised before the end of the conformity grace period, since doing so may be necessary to ensure conformity in the future.

      The proposal would allow regional conformity analyses that are started during the grace period to be based on either MOBILE6.2 or

      MOVES2010a. If the grace period ended on March 2, 2013, MOVES2010a would become the only approved motor vehicle emissions model for regional conformity analyses outside California at that time. This would mean that all new regional conformity analyses started after the end of the grace period must be based on MOVES2010a, even if the SIP is based

      Page 63579

      on MOBILE6.2 or earlier versions of MOBILE.

      For complete explanations of how MOVES2010a is to be implemented for transportation conformity, including details about using MOVES2010a during the grace period, refer to EPA's existing MOVES policy guidance.\8\

      \8\ ``Policy Guidance on the Use of MOVES2010 for State

      Implementation Plan Development, Transportation Conformity, and

      Other Purposes'' (EPA-420-B-09-046, December 2009) can be found on the EPA's transportation conformity Web site at:

    3. Rationale

      MOVES2010a is EPA's best tool for estimating criteria pollutant emissions, and it is a significant improvement over previous MOBILE models. State and local agencies have made significant progress to date in using MOVES2010a, and EPA supports these efforts and encourages that they continue. However, as discussed above, challenges related to start-up and model application have been much greater in the transition to MOVES2010a, compared to past transitions between MOBILE model versions. As a result, EPA has determined that a one-year extension of the MOVES2010a grace period is necessary for state and local agencies to complete the current transition. Today's action would ensure that state and local governments have the necessary time to implement the conformity rule as originally intended.

      Since 1993, the fundamental purpose of section 93.111(b) of the conformity rule has been to provide a sufficient amount of time for

      MPOs and other state and local agencies to adapt to using new emissions tools. As discussed above, the transition to a new emissions model for conformity involves more than learning to use the new model and preparing input data and model output. After model start-up is complete, state and local agencies also need to consider how the model affects regional conformity analysis results and whether SIP and/or transportation plan/TIP changes are necessary to assure future conformity determinations. EPA believes that the proposed one-time extension of the current MOVES2010a regional grace period is critical to assure future conformity determinations based on MOVES2010a.

      EPA has the discretion to establish an extended grace period for

      MOVES2010a, and today's action is consistent with CAA section 176(c)(1) requirements. EPA believes that the proposal to provide one additional year is appropriate due to this unique transition from MOBILE6.2 to

      MOVES2010a. This decision is consistent with the existing conformity criteria in section 93.111(b)(2) of the conformity rule that requires the length of the grace period to be based on ``the degree of change in the model and the scope of re-planning likely to be necessary by MPOs in order to assure conformity.''

      Today's proposal would not delay the use of MOVES2010a in SIP development or slow down past progress toward using the new model for regional conformity analyses. As noted above, many state and local agencies are already learning and applying MOVES2010a. Some are revising existing SIP budgets using the new model, while others may be incorporating MOVES2010a into new maintenance plans or clean data determinations. Under EPA's existing MOVES policy guidance, new or revised SIP budgets must still be based on MOVES2010a. For example,

      MOVES2010a continues to be required for attainment SIPs for the 2006 24-hour PM2.5NAAQS. Under the proposal, MOVES2010a would also be required for any regional conformity analyses prior to March 2, 2013 if SIP budgets based on MOVES2010 or MOVES2010a are approved or found adequate sooner.\9\

      \9\ See Questions 5, 6, and 11 of ``Policy Guidance on the Use of MOVES2010 for State Implementation Plan Development,

      Transportation Conformity, and Other Purposes'' (EPA-420-B-09-046,

      December 2009).

      In addition, today's action would not change the current MOVES2010a grace period for new PM2.5, PM10, and CO hot-spot analyses for project-level conformity determinations. EPA noted previously that a two-year conformity grace period was necessary to apply MOVES2010a for hot-spot analyses (75 FR 79370). However, the transition to MOVES2010a for project-level hot-spot analyses does not involve the complexity associated with the regional level, where SIP budgets and/or transportation plans/TIPs may need to be revised before regional conformity analyses based on MOVES2010a can be completed.

      Finally, in issuing this proposal, EPA is not proposing to proceed pursuant to or reopen as a general matter the process and length of conformity grace periods for future emissions model approvals, which were previously established in 1993 (58 FR 62211). The unique set of circumstances involved in the current transition warrants the proposed additional state and local flexibility before MOVES2010a is required for regional conformity analyses.

  9. Conformity SIPs

    The proposed MOVES2010a regional grace period extension would apply on the effective date of a final rule in all nonattainment and maintenance areas. Section 51.390(a) of the conformity rule states that the federal rule applies for the portion of the requirements that are not included in a state's approved conformity SIP.\10\ Section 51.390(b) further allows state conformity provisions to contain criteria and procedures that are more stringent than the federal requirements. However, in the case of states with conformity SIPs that include the grace period provision in 40 CFR 93.111(b)(1), EPA concludes that such states did not intend to require a shorter grace period than EPA, in consultation with DOT, believes is needed.

    Therefore, since the MOVES2010a grace period extension would be a new provision being added to the conformity rule, it is not included in any current state conformity SIP and therefore would apply immediately, if finalized, in all areas pursuant to section 51.390(a).

    \10\ A conformity SIP is required by the CAA and contains a state's conformity requirements, including the state's specific interagency consultation procedures.

    In addition, section 51.390(c) of the conformity rule requires states to submit a new or revised conformity SIP to EPA within 12 months of the Federal Register publication date of final conformity rules in certain situations. States with approved conformity SIPs that are prepared in accordance with current CAA requirements would not be required to submit new conformity SIP revisions under a final rule, since section 93.111 of the conformity rule is not contained in these

    SIPs. A conformity SIP prepared in accordance with current CAA requirements contains only the state's criteria and procedures for interagency consultation (40 CFR 93.105) and two additional provisions related to written commitments for certain control and mitigation measures (40 CFR 93.122(a)(4)(ii) and 93.125(c)). However, states with approved conformity SIPs that include section 93.111 from a previous rulemaking would be required to submit a SIP revision within 12 months of the publication date of any final rule, although EPA strongly encourages these states to submit a SIP revision with only the three required provisions.\11\ A state without an approved conformity SIP would not be required to submit a new conformity SIP

    Page 63580

    within one year of a final rule, but previous conformity SIP deadlines continue to apply.

    \11\ The conformity SIP may contain provisions more stringent than the federal requirements, and in these cases, states would specify this intention in its original conformity SIP submission.

    For additional information on conformity SIPs, please refer to the

    January 2009 guidance entitled, ``Guidance for Developing

    Transportation Conformity State Implementation Plans'' available on

    EPA's Web site at:

  10. Statutory and Executive Order Reviews

    1. Executive Order 12866: Regulatory Planning and Review

      Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is a ``significant regulatory action.'' Accordingly, EPA submitted this action to the Office of Management and Budget (OMB) for review under Executive Orders 12866 and 13563 (76 FR 3821, January 21, 2011) and any changes made in response to OMB recommendations have been documented in the docket for this action.

    2. Paperwork Reduction Act

      This action would not impose any new information collection burden.

      The information collection requirements of EPA's existing transportation conformity regulations and the proposed revisions in today's action are already covered by EPA information collection request (ICR) entitled, ``Transportation Conformity Determinations for

      Federally Funded and Approved Transportation Plans, Programs and

      Projects.'' OMB has previously approved the information collection requirements contained in the existing regulations at 40 CFR Part 93 under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB control number 2060-0561. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR Part 9.

    3. Regulatory Flexibility Act

      The Regulatory Flexibility Act (RFA) generally requires an Agency to prepare a regulatory flexibility analysis of rules subject to notice-and-comment rulemaking requirements under the Administrative

      Procedure Act or any other statute 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 organizations and small government jurisdictions.

      For purposes of assessing the impacts of today's proposal on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration's (SBA) regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise that is independently owned and operated and is not dominant in its field.

      After considering the economic impacts of today's proposed rule on small entities, I certify that this action would not have a significant economic impact on a substantial number of small entities. This proposal would directly affect federal agencies and MPOs that, by definition, are designated under federal transportation laws only for metropolitan areas with a population of at least 50,000. These organizations do not constitute small entities within the meaning of the RFA. Therefore, this proposal would not impose any requirements on small entities.

    4. Unfunded Mandates Reform Act (UMRA)

      This proposal does not contain a Federal mandate that may result in expenditures of $100 million or more for state, local, and tribal governments, in the aggregate, or the private sector in any one year.

      This rule would merely implement already established law that imposes conformity requirements and would not itself impose requirements that may result in expenditures of $100 million or more in any year. Thus, today's proposal is not subject to the requirements of sections 202 and 205 of the UMRA.

      This proposal is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. This proposal would not significantly or uniquely impact small governments because it directly affects federal agencies and MPOs that, by definition, are designated under federal transportation laws only for metropolitan areas with a population of at least 50,000.

    5. Executive Order 13132: Federalism

      This proposal does not have federalism implications. It would not have substantial direct effects on states, on the relationship between the national government and states, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. The CAA requires conformity to apply in certain nonattainment and maintenance areas as a matter of law, and today's action would merely revise one provision for transportation planning entities in subject areas to follow in meeting their existing statutory obligations. Thus, Executive Order 13132 does not apply to this proposal.

    6. Executive Order 13175: Consultation and Coordination With Indian

      Tribal Governments

      This action does not have tribal implications, as specified in

      Executive Order 13175 (65 FR 67249, November 9, 2000). The CAA requires transportation conformity to apply in any area that is designated nonattainment or maintenance by EPA. Because today's proposal would not significantly or uniquely affect the communities of Indian tribal governments, Executive Order 13175 does not apply to this action.

    7. Executive Order 13045: Protection of Children From Environmental

      Health and Safety Risks

      This proposal is not subject to Executive Order 13045 (62 FR 19885,

      April 23, 1997) because it is not economically significant as defined in Executive Order 12866, and because the Agency does not believe the environmental health or safety risks addressed by this action present a disproportionate risk to children.

    8. Executive Order 13211: Actions Concerning Regulations That

      Significantly Affect Energy Supply, Distribution, or Use

      This proposal is not a ``significant energy action'' as defined in

      Executive Order 13211 (66 FR 18355 (May 22, 2001)), because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. It would not create a serious inconsistency or otherwise interfere with an action taken or planned by another agency regarding energy. This action is not subject to

      Executive Order 13211 because it does not have any adverse energy effects.

  11. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement

    Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., material specifications, test methods,

    Page 63581

    sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards. This proposal does not involve technical standards. Therefore, EPA is not considering the use of any voluntary consensus standards.

    1. Executive Order 12898: Federal Actions To Address Environmental

    Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.

    EPA has determined that this action would not have disproportionately high and adverse human health or environmental effects on minority or low-income populations. The proposed rule involves a minor revision that provides administrative relief but does not change the conformity rule's underlying requirements for regional conformity analyses.
