06-72. Determination of Attainment, Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Indiana; Redesignation of the Vigo County Nonattainment Area to Attainment of the 8-Hour Ozone Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

EPA is determining that the Vigo County 8-hour ozone nonattainment area has attained the 8-hour ozone National Ambient Air Quality Standard (NAAQS). EPA is approving a request from the State of Indiana, submitted on July 5, 2005 and supplemented on October 20, 2005 and November 4, 2005, to redesignate Vigo County from nonattainment to attainment for the 8-hour ozone NAAQS. EPA's approval of the redesignation request is based on the determination that Vigo County and the State of Indiana have met the criteria for redesignation to attainment set forth in the Clean Air Act (CAA), including the determination that Vigo County has attained the 8-hour ozone standard. In conjunction with this approval, EPA is approving the State's plan for maintaining the 8-hour ozone NAAQS in Vigo County through 2015 as a revision to the Indiana State Implementation Plan (SIP). EPA also finds as adequate and approves the 2015 Volatile Organic Compounds (VOC) and Nitrogen Oxides (NO_X) Motor Vehicle Emission Budgets (MVEBs) for this area.

DATES:

This rule is effective on February 6, 2006.

I. What Is the Background for This Rule?

EPA has determined that ground-level ozone is detrimental to human health. On July 18, 1997, the EPA promulgated an 8-hour ozone NAAQS (62 FR 38856) of 0.08 parts per million parts of air (0.08 ppm). This standard is violated in an area when any ozone monitor in the area records an average of the annual fourth-highest daily maximum 8-hour ozone concentrations equaling or exceeding 0.085 ppm over a three-year period. Ground-level ozone is not emitted directly by sources. Rather, emitted VOC and NO_X react in the presence of sunlight to form ground-level ozone along with other secondary compounds. VOC and NO_X are referred to as “ozone precursors.”

In accordance with section 107(d) of the CAA as amended in 1977, EPA designated Vigo County as an ozone nonattainment area for the 8-hour ozone NAAQS based on ozone data collected in this area during the 2001-2003 period. The Federal Register notice making this designation was signed on April 15, 2004, and was published on April 30, 2004 (69 FR 23857).

The Clean Air Act contains two sets of provisions—subpart 1 and subpart 2—that address planning and emission control requirements for nonattainment areas (both subparts are found in title I, part D of the CAA). Subpart 1 contains general, less prescriptive requirements for nonattainment areas governed by any NAAQS, and applies to all nonattainment areas. Subpart 2 contains more specific requirements for certain ozone nonattainment areas, and applies to ozone nonattainment areas classified under section 181 of the CAA.

In the April 30, 2004 ozone designation rulemaking, EPA divided 8-hour ozone nonattainment areas into the categories of subpart 1 nonattainment and subpart 2 nonattainment based on their 8-hour ozone design values (i.e., the three-year average annual fourth-highest daily maximum 8-hour ozone concentrations at the worst-case ozone monitoring sites in the designated areas) and their 1-hour ozone design values (i.e., the fourth-highest daily maximum 1-hour ozone concentrations over the three-year period at the worst-case monitoring sites in the designated areas).^[1] 8-hour ozone nonattainment areas with 1-hour ozone design values equaling or exceeding 0.121 ppm were designated as classified nonattainment areas (as nonattainment areas required to meet the requirements of subpart 2 of the CAA). All other 8-hour nonattainment areas were designated as “basic” nonattainment areas subject only to the requirements of subpart 1 of the CAA.

In the April 30, 2004 designation rulemaking, Vigo County was designated as nonattainment for the 8-hour ozone standard, and was identified as a subpart 1 basic nonattainment area. This designation was based on ozone data collected in Vigo County from the period of 2001-2003.

On July 5, 2005, the State of Indiana requested redesignation of Vigo County to attainment of the 8-hour ozone NAAQS based on ozone data collected during the period of 2002-2004. This request was supplemented with submittals dated October 20, 2005 and November 4, 2005. This redesignation request also included a 10-year ozone maintenance plan for Vigo County and the VOC and NO_X MVEBs for Vigo County are based on emission projections in the ozone maintenance plan.

On November 23, 2005, EPA published a proposed rule (70 FR 70751), proposing to: (1) Determine that Vigo County has attained the 8-hour ozone NAAQS and to approve Indiana's request to redesignate Vigo County to attainment of the 8-hour ozone NAAQS; (2) approve Indiana's ozone maintenance plan for Vigo County; and (3) approve the 2015 VOC and NO_X MVEBs for Vigo County and notify the public that these MVEBs are adequate for purposes of transportation conformity. This proposed rule established a 30-day public comment period.

II. What Comments Did We Receive on the Proposed Action?

EPA provided a 30-day review and comment period on the proposal published in the Federal Register on November 23, 2005 (70 FR 70751). We received no comments on our proposed rulemaking.

III. What Are Our Final Actions?

EPA is making a determination that Vigo County has attained the 8-hour ozone NAAQS, and EPA is approving the redesignation of Vigo County from nonattainment to attainment for the 8-hour ozone NAAQS. After evaluating Indiana's redesignation request, EPA has determined that it meets the redesignation criteria set forth in section 107(d)(3)(E) of the CAA. The final approval of this redesignation request changes the official designation for Vigo County from nonattainment to attainment for the 8-hour ozone standard.

EPA is also approving the maintenance plan SIP revision for Vigo County. Approval of the maintenance plan is based on Indiana's demonstration that the plan meets the requirements of section 175A of the CAA. Additionally, EPA is finding adequate and approving the 2015 MVEBs submitted by Indiana in conjunction with the redesignation request.

No comments were received on the proposed rule. Therefore, all proposed actions are being finalized here.

IV. Statutory and Executive Order Review

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

Because it is not a “significant regulatory action” under Executive Order 12866 or a “significant energy action,” 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. Redesignation of an area to attainment under section 107(d)(3)(E) of the Clean Air Act does not impose any new requirements on small entities. Redesignation is an action that affects the status of a geographical area and does not impose any new regulatory requirements on sources. 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). Redesignation is an action that merely affects the status of a geographical area, and does not impose any new requirements on sources, or allows a state to avoid adopting or implementing additional requirements, and does not alter the relationship or 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. Redesignation is an action that affects the status of a geographical area but does not impose any new requirements on sources. 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.

Environmental Justice

Executive Order 12898 establishes a Federal policy for incorporating environmental justice into Federal agency actions by directing agencies to identify and address, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority and low-income populations. As explained elsewhere in this document (see responses to Comments 5 and 9), today's action is designed to prevent violations of the health-based national ambient air quality standard. It does not result in the relaxation of control measures on existing sources and therefore will not cause emissions increases from those sources. Overall, as discussed in response to Comments 5 and 9, emissions in the area are projected to decline following the redesignation. Thus, today's action will not have disproportionately high and adverse effects on any communities in the area, including minority and low-income communities.

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 March 6, 2006. 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).)
