AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

The EPA is approving revisions to the State Implementation Plan (SIP) submitted by the Florida Department of Environmental Protection (FDEP) on December 20, 2002. This SIP revision satisfies the requirement of the Clean Air Act (CAA) as amended in 1990 for the second 10-year update for the Tampa Bay area (Hillsborough and Pinellas Counties) 1-hour ozone maintenance plan. For transportation purposes, EPA is also finalizing its adequacy determination of the new Motor Vehicle Emissions Budgets (MVEBs) for the year 2015. EPA has determined that the MVEBs for the year 2015 contained in this SIP revision are adequate for transportation conformity purposes.

DATES:

This direct final rule is effective May 28, 2004, without further notice, unless EPA receives adverse comment by April 28, 2004. If adverse comment is received, EPA will publish a timely withdrawal of the direct final rule in the Federal Register and inform the public that the rule will not take effect.

SUPPLEMENTARY INFORMATION:

I. Background

The air quality maintenance plan is a requirement of the 1990 CAA for nonattainment areas that come into compliance with the national ambient air quality standard (NAAQS). The Tampa Bay area (Hillsborough and Pinellas Counties) was not in compliance with the 1-hour ozone air quality standard until 1990, when air quality measurements showed compliance with the standard. The State subsequently requested that EPA redesignate these counties as attainment/maintenance for the 1-hour ozone standard. Included with this request was a 10-year air quality maintenance plan covering the years 1995 to 2005. This plan was developed in accordance with the appropriate guidelines. The EPA published approval of this plan on December 7, 1995, with an effective date of February 6, 1996 (60 FR 62748).

Subsequent revisions to this maintenance plan have been made. The current plan was approved by EPA on August 15, 2002, and became effective on October 15, 2002 (66 FR 53314). FDEP revised the original plan to update emissions inventories reflecting more accurate emission estimates, to define specific MVEBs, and to remove emissions reduction credits attributable to the motor vehicle inspection program (MVIP) (67 FR 53314).

II. Analysis of State's Submittal

On December 20, 2002, the FDEP submitted revisions to Florida's SIP to provide a 10-year update to the maintenance plan as required by section 175A(b) of the CAA as amended in 1990. The underlying strategy of the maintenance plan is to maintain compliance with the 1-hour ozone standard by assuring that current and future emissions of Volitile Organic Compound (VOC) and Nitrogen Oxide (NO_X) remain at or below attainment year emission levels. The estimated emissions of ozone precursors (i.e., VOC and NO_X) for the two counties for the Tampa Bay area during the 1990 ozone season are provided in the following table. Projected VOC and NO_X emissions for 2005 and 2015 are also provided.

This SIP revision satisfies the requirement of the CAA for the second 10-year update for the Tampa Bay area 1-hour ozone maintenance plan. Changes to the current maintenance plan include revisions to the emissions inventory for both on-road and non-road mobile sources, reflecting improved methodologies contained in the MOBILE6 and NONROAD emission models. New emissions data for both the base year (1990 attainment year) and the projected years (2005 and 2015) are calculated.

III. Finalization of MVEBs Adequacy Determination for Transportation Conformity Purposes

The second 10-year update for the Tampa Bay area 1-hour ozone maintenance plan also contains updated MVEBs in support of the transportation conformity process. These updated MVEBs are defined for VOC and NO_X for each county in the Tampa Bay maintenance area. The updated budgets for 2005 replace the previous MVEBs contained in the first maintenance plan, which were based on an older emissions estimate using MOBILE5 emission factors for on-road motor vehicles. Additionally, this maintenance plan update provides new MVEBs for the year 2015.

The availability of the SIP with MVEBs for 2015 was placed on EPA's adequacy web page on January 7, 2003. No request for this SIP submittal or adverse comments were received by the end of the public comment period on February 7, 2003. In this action, EPA finds the 2015 MVEBs adequate for transportation conformity, and is approving the MVEBs for 2005 and 2015. Note, since the 2005 MVEB are replacing existing 2005 MVEBs, these budgets are not subject to EPA's adequacy process. This is because EPA generally will not review the adequacy of a budget from a submitted SIP that revises an existing approved SIP with budgets for the same year and CAA requirement because as a matter of law, a submitted SIP may not supersede an approved SIP for the same CAA requirement, year, and pollutant (68 FR 38974).

Under the CAA, States are required to submit, at various times, control strategy SIPs and maintenance plans in ozone areas. These control strategy SIPs (e.g., reasonable further progress SIPs and attainment demonstration SIPs) and maintenance plans create MVEBs for criteria pollutants and/or their precursors to address pollution from cars and trucks. The MVEBs are the portion of the total allowable emissions that is allocated to highway and transit vehicle use and emissions. The MVEBs serve as a ceiling on emissions from an area's planned transportation system. 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 MVEBs in the SIP and revise the MVEBs.

Under section 176(c) of the CAA, new transportation projects, such as the construction of new highways, must “conform” to (e.g., be consistent with) the part of the State's air quality plan that addresses pollution from cars and trucks. “Conformity” to the SIP means that transportation activities will not cause new air quality violations, worsen existing violations, or delay timely attainment of the national ambient air quality standards. If a transportation plan does not “conform,” most projects that would expand the capacity of roadways cannot go forward. Regulations at 40 CFR part 93 set forth by EPA policy, criteria, and procedures for demonstrating and assuring conformity of such transportation activities to a SIP.

When reviewing submitted “control strategy” SIPs or maintenance plans containing MVEBs, EPA must affirmatively find the MVEBs budget contained therein “adequate” for use in determining transportation conformity before they can be used for such purposes. Once EPA affirmatively finds the submitted MVEB is adequate for transportation conformity purposes, that MVEB can be used by the state and federal agencies in determining whether proposed transportation projects “conform” to the state implementation plan as required by section 176(c) of the Clean Air Act. EPA's substantive criteria for determining “adequacy” of MVEBs is set out in 40 CFR 93.118(e)(4).

EPA's process for determining “adequacy” consists of three basic steps: public notification of a SIP submission, a public comment period, and EPA's adequacy finding. This process for determining the adequacy of submitted SIP MVEBs is set out in EPA's May 14, 1999 guidance, “Conformity Guidance on Implementation of March 2, 1999, Conformity Court Decision.” This guidance is incorporated into EPA's June 30, 2003, proposed rulemaking entitled “Transportation Conformity Rule Amendments: Response to Court Decision and Additional Rule Changes” (68 FR 38974). EPA follows this guidance in making its adequacy determination.

Specific emissions budgets are defined for VOC and NO_X for the Tampa Bay area in the Florida submittal. Pursuant to 40 CFR 93.124(d), Tampa Bay has elected to allocate subarea budgets for each of the counties for the purpose of transportation conformity. The specific MVEBs for Hillsborough County in 2005 and 2015 are 53.6 tpd for VOC and 91.8 tpd for NO_X. Pinellas County's MVEBs for 2005 and 2015 are 30.8 tpd for VOC and 52.5 tpd for NO_X. With this allocation, each county must demonstrate conformity to the county-specific subarea budgets. The chart below provides a summary of the county-specific subarea budgets.

MVEB

[tons per day]

County	Pollutant	2005	2015
Hillsborough	VOC	53.6	53.6
	NOX	91.8	91.8
Pinellas	VOC	30.8	30.8
	NOX	52.5	52.5
Total	VOC	84.4	84.4
	NOX	144.3	144.3

The MVEBs are defined for each Tampa Bay county, for 2005 and 2015, in the State's submittal. The values, for both years, are equal to the 2005 on-road mobile source projected level of emissions plus a buffer of 25 percent. This buffer, which is an allocation from the safety margin, accounts for uncertainty in the projections and is available because of significant reductions of VOC and NO_X that have occurred, and are projected to occur, primarily from mobile sources. The MVEBs are constrained in each of the budget years to assure that the total emissions (i.e., all source categories) do not exceed the 1990 attainment year emissions. In no case are the projected total emissions from mobile sources for any year, greater than the attainment year emissions totals for either VOC or NO_X.

Under 40 CFR 93.101, the term safety margin is the difference between the attainment level (from all sources) and the projected level of emissions (from all sources) in the maintenance plan. The attainment level of emissions is the level of emissions during one of the years in which the area met the air quality health standard. The safety margin credit can be allocated to the transportation sector, however the total emission level must stay below the attainment level.

IV. Final Action

EPA is approving the second 10-year update for the Tampa Bay 1-hour ozone maintenance plan. In this action, EPA also finds the 2015 MVEBs adequate for transportation conformity purposes and is approving the MVEBs for 2005 and 2015. EPA's adequacy determination for the 2015 MVEBs is based on EPA's finding that the substantive criteria for determining adequacy of a MVEB, under 40 CFR 93.118(e)(4), have been met. The MVEBs will be available for use upon the effective date of this action. The MVEBs, based on the on-road mobile sources, are to be used by the local metropolitan planning organizations and transportation authorities to assure that transportation plans, programs, and projects are consistent with, and conform to, the long term maintenance of acceptable air quality in the Tampa Bay area.

The EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed. This rule will be effective May 28, 2004, without further notice unless the Agency receives adverse comments by April 28, 2004.

If the EPA receives such comments, then EPA will publish a document withdrawing the final rule and informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. The EPA will not institute a second comment period. Parties interested in commenting should do so at this time. If no such comments are received, the public is advised that this rule will be effective on May 28, 2004, and no further action will be taken on the proposed rule. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.

VI. 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. 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 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.). 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).

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). 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. 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.

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. 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.).

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 May 28, 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).)
