In November of 1999, EPA issued two memoranda  to articulate its policy regarding states that incorporated MOBILE5-based interim Tier 2 standard  benefits into their 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 MOBILE5-based 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.
On December 26, 2000, Illinois submitted a revision to the One-Hour Ozone Attainment Demonstration SIP for the Chicago severe ozone area. This SIP revision included, among other things, revised MVEBs using interim MOBILE5-based estimates of the Tier 2 standards and an enforceable commitment to revise the attainment demonstration using the MOBILE6 model, including MVEBs, within two years of the release of the model. Additional information on EPA's final approval of Illinois' December 26, 2000 submittal is in the November 13, 2001 Federal Register (66 FR 56931).
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 notice constituted the start of the two year time period in which Illinois was required to revise its One-Hour Ozone Attainment Demonstration SIP using the MOBILE6 model. Illinois was required to submit this SIP revision to EPA by January 29, 2004.
III. What Is MOBILE6?
MOBILE is an EPA emissions factor model for estimating pollution from on-road motor vehicles in states outside of California. MOBILE calculates emissions of volatile organic compounds (VOCs), oxides of nitrogen (NOX) and carbon monoxide (CO) from passenger cars, motorcycles, buses, and light-duty and heavy-duty trucks. The model accounts for the emission impacts of factors such as changes in vehicle emission standards, changes in vehicle populations and activity, and variation in local conditions such as temperature, humidity, fuel quality, and air quality programs.
MOBILE is used to calculate current and future inventories of motor vehicle emissions at the national and local level. These inventories are used to make decisions about air pollution policies and programs at the local, state and national level. Inventories based on MOBILE are also used to meet the federal Clean Air Act's SIP and transportation conformity requirements.
MOBILE6 is the first major update of the MOBILE model since 1993. The MOBILE model was first developed in 1978. It has been updated many times to reflect changes in the vehicle fleet and fuels, to incorporate EPA's growing understanding of vehicle emissions, and to cover new emissions regulations and modeling needs. Although some minor updates were made in 1996 with the release of MOBILE5b, MOBILE6 is the first major revision to MOBILE since MOBILE5a was released in 1993.
IV. What Is the Purpose and Content of Illinois' Submittal?
To address its enforceable commitment made in the December 26, 2000, Attainment Demonstration SIP revision, the State submitted a requested SIP revision on April 11, 2003, which revises the 2005 and 2007 motor vehicle emissions inventories and the 2005 and 2007 MVEBs using the MOBILE6 model. The April 11, 2003, submittal demonstrates that the new levels of motor vehicle emissions calculated using MOBILE6 continue to support achievement of the projected attainment of the one-hour ozone NAAQS for the Chicago area.
V. What Are the Revised MOBILE6 Inventories?
Table 1 below summarizes the revised motor vehicle emissions inventories in tons per summer day (tpd). The State developed these revised inventories using the latest planning assumptions, including updated vehicle registration data, vehicle miles traveled (VMT), speeds, fleet mix, and SIP control measures. EPA is approving these revised 2005 and 2007 motor vehicle emissions inventories.
|Chicago Severe Area||151.11||127.42||280.40|
VI. Are the Revised MOBILE6 Inventories Consistent With Illinois' One-Hour Ozone Attainment Demonstration?
Illinois' attainment demonstration used photochemical grid modeling. For one-hour ozone, the daily peak one-hour concentration predicted in every grid cell by the model was compared to the ozone standard concentration of 124 parts per billion (ppb). This is best represented by the deterministic approach described in the 1996 Guidance on Use of Modeled Results to Demonstrate Attainment of the Ozone NAAQS, EPA, June 1996. That guidance also describes a statistical approach which allows a specific number of exceedances of the standard. However, final attainment is still determined in an absolute sense by comparing a predicted concentration with the one-hour standard value of 124 ppb. 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”  and “Clarification of Policy Guidance for MOBILE6 in Mid-course Review Start Printed Page 53890Areas.”  This policy requires that new MOBILE6 MVEBs in areas that demonstrated attainment with absolute modeling meet two conditions. First, the new MOBILE6 based mobile source inventories are compared to the MOBILE5 based inventories for the attainment year. If the MOBILE6 mobile emissions are less than or equal to the MOBILE5 emissions, then the SIP continues to demonstrate attainment. Second, EPA's policy guidance requires the State to consider whether growth and control strategy assumptions for non-motor vehicle sources (i.e., point, area, and non-road mobile sources) are still accurate at the time the State developed the submittal.
Consistent with this policy guidance, Illinois' updated MOBILE6 inventories were less than the MOBILE5 attainment demonstration inventories for the Chicago area. It should be noted that Illinois used the latest planning assumptions in development of the updated inventories. Illinois reviewed the growth and control strategy assumptions for non-motor vehicle sources, and concluded that these assumptions continue to be valid and support the one-hour Ozone Attainment Demonstration.
In summary, Illinois' April 11, 2003, 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 one-Hour Ozone NAAQS by the attainment date of 2007.
VII. Are Illinois' Motor Vehicle Emissions Budgets Approvable?
Table 2 below summarizes Illinois' revised 2005, and 2007 MVEBs contained in the April 11, 2003, submittal. The State developed MVEBs using the latest planning assumptions, including updated vehicle registration data, vehicle miles of travel (VMT), speeds, fleet mix, and SIP control measures. The Illinois submittal met all applicable requirements and EPA is approving these budgets.
|Chicago Severe Area||151.11||127.42||280.40|
VIII. EPA Action
EPA is approving the Illinois SIP revision submitted on April 11, 2003. This submittal revises Illinois' 2005, and 2007 motor vehicle emission inventories and 2005, and 2007 MVEBs using MOBILE6 for the Chicago severe 1-hour ozone nonattainment area.
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, EPA is proposing to approve the SIP revision should adverse written comments be filed. This action will be effective without further notice unless EPA receives relevant adverse written comments by October 15, 2003. Should the Agency receive such comment, we will publish a final rule informing the public that this action will not take effect. Any parties interested in commenting on this action should do so at this time. If we do not receive comments, this action will be effective on November 14, 2003.
IX. Statutory and Executive Order Reviews
Executive Order 12866: Regulatory Planning and Review
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
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 pre-existing 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. 104-4).
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 Start Printed Page 53891EPA, 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 November 14, 2003. 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).)Start List of Subjects
