Environmental Protection Agency (EPA).
EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. This revision amends Pennsylvania's ten-year plan to maintain the 1-hour ozone national ambient air quality standard (NAAQS) in the Reading area (Berks County). The maintenance plan is being amended to revise the attainment year inventories and motor vehicle emission budgets using MOBILE6. The contingency measures portion of the plan is also being amended. This action is being taken under the Clean Air Act.
Written comments must be received on or before December 19, 2003.

On May 7, 1997 ( 62 FR 24826), EPA approved Pennsylvania's redesignation request and ten year plan for continued maintenance of the 1-hour ozone NAAQS in the Reading area as a revision to the Pennsylvania SIP. This maintenance plan included, among other things, MOBILE5-based motor vehicle emissions budgets (MVEBs).
On October 14, 2003, the Pennsylvania Department of Environmental Protection (DEP) submitted a request that EPA parallel process revisions to the Pennsylvania SIP's 1-hour ozone maintenance plan for the Reading area.
The maintenance plan identifies and establishes the applicable MVEBs for the Reading area to which the area's transportation improvement program and long range transportation plan must conform. Conformity to MVEBs in a SIP means that transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the NAAQS. The Reading area maintenance plan identifies and establishes the applicable MVEBs for the Reading area for both volatile organic compounds (VOC) and nitrogen oxides (NOX), which are precursors of ground level ozone, for the years 1992, 2004, and 2007.
The MOBILE model is an EPA emissions factor model for estimating pollution from on-road motor vehicles. The MOBILE model calculates emissions of VOCs, 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. The MOBILE model 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. MOBILE-based inventories are also used to meet the Federal Clean Air Act's SIP and transportation conformity requirements.
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. EPA released MOBILE6, a new version of the motor vehicle emissions factor model on January 29, 2002 (67 FR 4254). 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. Beginning in January of 2004, all conformity determinations for new Transportation Improvement Programs and/or Transportation Plans will be required to use the MOBILE6 emissions model to demonstrate conformity.
II. Summary of the Proposed SIP Revisions to the Reading Area Maintenance Plan
A. Revisions to the Motor Vehicle Emission Budgets (MVEBs)
In the original maintenance plan approved for the Reading area on May 7, 1997 (62 FR 24826), emissions growth was projected for all source categories (point, area, and highway mobile) starting with the year that the area attained the NAAQS (1992). Those original mobile emissions budgets were projected based on the MOBILE5 emissions model. The October 14, 2003, proposed SIP revision amends the mobile inventories for the attainment year (1992) and the MVEBs for 2004 and 2007 using MOBILE6.
B. Revisions to the Contingency Measures
In the original maintenance plan for the Reading area, the Commonwealth's motor vehicle inspection and Start Printed Page 65235maintenance (I&M) program was identified as a contingency measure. The October 14, 2003, proposed SIP revision moves the I&M program from the contingency measures portion of the plan and makes it part of the maintenance strategy. Improved rule effectiveness will remain as a contingency measure in the maintenance plan.
III. EPA's Evaluation of the Proposed Revisions to the Reading Area Maintenance Plan
A. The Revised Attainment Year (1992) Emission Inventories
The DEP's October 14, 2003, proposed revisions revise the 1992 attainment year motor vehicle emissions inventories and the 2004 and 2007 MVEBs using the MOBILE6 model. 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”  . EPA's review of the DEP's October 14, 2003, submittal indicates that it has appropriately applied this policy. EPA policy guidance also requires the Commonwealth to consider whether growth and control strategy assumptions for non-motor vehicle sources (i.e., point, area, and non-road mobile sources) were still accurate at the time the October 14, 2003, proposed revision was developed. Pennsylvania has reassessed the growth and control strategy assumptions for non-motor vehicle sources, and concluded that these assumptions continue to be valid for the 1-hour ozone maintenance demonstration for the Reading area.
Table 1 summarizes the MOBILE6-based motor vehicle emissions inventories in tons per summer day (tpd) for the 1992 attainment year in the Reading area.
|Maintenance area||1992 Attainment year|
|VOC (tpd)||NOX (tpd)|
B. The Revised Motor Vehicle Emissions Budgets (MVEBs)
For the Reading area maintenance plan, the MVEBs are the projected on-road mobile source components of the 2004 and 2007 maintenance inventories. Table 2 below summarizes Pennsylvania's proposed revised MOBILE6-based budgets. These budgets were developed using the latest planning assumptions, including 2002 vehicle registration data, vehicle miles traveled, speeds, fleet mix, and SIP control measures. Because DEP's October 14, 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 maintenance of the 1-hour ozone NAAQS, EPA is proposing to approve these budgets.
|VOC (tpd)||NOX (tpd)||VOC (tpd)||NOX (tpd)|
|Reading Area (Berks County)||17.02||28.99||13.81||23.06|
The October 14, 2003, submittal demonstrates that the new levels of motor vehicle emissions calculated using MOBILE6 continue to support the demonstration of maintenance of the 1-hour ozone NAAQS for the Reading area. This is evidenced by the fact that the 2004 and 2007 MVEBs shown in Table 2 continue to be well below the 1992 MOBILE6 based MVEBs for their attainment year.
IV. EPA's Proposed Action
EPA is proposing to approve the Commonwealth of Pennsylvania's proposed revisions to the maintenance plan for the Reading area which were submitted on October 14, 2003. Long term maintenance of the NAAQS is deemed to be demonstrated when total projected growth in emissions in all categories remains below the level of emissions that occurred in the attainment year. EPA's review of the DEP's October 14, 2003, submittal indicates that the proposed revisions to the maintenance plan continue to demonstrate long term maintenance of the 1-hour ozone standard for the Reading area. These revisions are being proposed under a procedure called parallel processing, whereby EPA proposes rulemaking action concurrent with the Commonwealth's procedures for amending its SIP. If the proposed revisions are substantially changed in areas other than those identified in this notice, EPA will evaluate those changes and may publish another notice of proposed rulemaking. If no substantial changes are made other than those areas cited in this notice, EPA will publish a Final Rulemaking Notice on the revisions. The final rulemaking action by EPA will occur only after the SIP revisions have been adopted by Pennsylvania and submitted formally to EPA for incorporation into the SIP.

V. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. 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). This proposed action merely proposes to approve Commonwealth law as meeting Federal requirements and imposes no additional requirements beyond those imposed by Commonwealth law. Accordingly, the Administrator certifies that this proposed 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.). Because this rule proposes to approve 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).
This proposed 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). 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 proposes to approve 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. This proposed 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.
In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of Start Printed Page 65237the 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.
This rule proposing to approve Pennsylvania's proposed revisions to the Reading area's maintenance plan for the 1-hour ozone NAAQS, submitted to EPA on October 14, 2003, for parallel-processing, does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).Start List of Subjects
