 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: EPA is approving the requests of Ohio and Indiana to redesignate the Ohio and Indiana portions of the Cincinnati-Hamilton, OH-KY-IN 8-hour ozone nonattainment area, “the Cincinnati-Hamilton area,” to attainment for that standard, because these requests meet the statutory requirements for redesignation under the Clean Air Act (CAA). The Ohio Environmental Protection Agency (Ohio EPA) and the Indiana Department of Environmental Management (IDEM) submitted these requests on December 14, 2009, and January 21, 2010, respectively. (EPA will address the Kentucky portion of the Cincinnati-Hamilton area in a separate rulemaking action.) These approvals involve several related actions. EPA is making a determination under the CAA that the Cincinnati-Hamilton area has attained the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). The Cincinnati-Hamilton area includes Butler, Clermont, Clinton, Hamilton, and Warren Counties in Ohio, Lawrenceburg Township in Dearborn County, Indiana, and Boone, Campbell, and Kenton Counties in Kentucky. This determination is based on three years of complete, quality-assured ambient air quality monitoring data for the 2007-2009 ozone seasons that demonstrate that the 8-hour ozone NAAQS has been attained in the entire Cincinnati-Hamilton area. EPA is also approving, as revisions to the Ohio and Indiana State Implementation Plans (SIPs), the States' plans for maintaining the 8-hour ozone NAAQS through 2020 in the area. EPA is approving the 2002 base year emissions inventory submitted by IDEM on June 13, 2007, as meeting the base year emissions inventory requirement of the CAA for the Indiana portion of the Cincinnati-Hamilton area. EPA is approving the 2005 base year emissions inventory submitted by Ohio EPA as part of its redesignation request as meeting the base year emissions inventory requirements of the CAA for the Ohio portion of the Cincinnati-Hamilton area. Finally, EPA finds adequate and is approving the States' 2015 and 2020 Motor Vehicle Emission Budgets (MVEBs) for the Ohio and Indiana portion of the Cincinnati-Hamilton area.
 DATES: This final rule is effective May 11, 2010.

SUPPLEMENTARY INFORMATION: Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA. This supplementary information section is arranged as follows: Table of Contents I. What is the background for these actions? II. What comments did we receive on the proposed rule? III. What action is EPA taking? IV. Statutory and Executive Order Reviews. I. What is the background for these actions? The background for today's actions is discussed in detail in EPA's February 26, 2010, proposal (75 FR 8871). In that rulemaking, we noted that, under EPA regulations at 40 CFR part 50, the 8-hour ozone standard is attained when the three-year average of the annual fourth-highest daily maximum 8-hour average ozone concentrations is less than or equal to 0.08 ppm. (
                    *See*69 FR 23857 (April 30, 2004) for further information.) Under the CAA, EPA may redesignate nonattainment areas to attainment if sufficient complete, quality-assured data are available to determine that the area has attained the standard and if it meets the other CAA redesignation requirements in section 107(d)(3)(E). The Ohio EPA and IDEM submitted requests to redesignate the Ohio and Indiana portions of the Cincinnati-Hamilton area to attainment for the 8-hour ozone standard on December 14, 2009, and January 21, 2010, respectively. The redesignation requests included three years of complete, quality-assured data for the period of 2007 through 2009, indicating the 8-hour NAAQS for ozone, as promulgated in 1997, had been attained for the Cincinnati-Hamilton area. The February 26, 2010, proposed rule provides a detailed discussion of how Ohio and Indiana met this and other CAA requirements. II. What comments did we receive on the proposed rule? EPA provided a 30-day review and comment period. The comment period closed on March 29, 2010. We received no comments on the proposed rule. III. What action is EPA taking? EPA is making a determination that the Cincinnati-Hamilton area has attained the 1997 8-hour ozone NAAQS. EPA is also approving the maintenance plan SIP revisions for the Ohio and Indiana portions of the Cincinnati-Hamilton area. EPA's approval of the maintenance plans is based on the States' demonstrations that the plans meet the requirements of section 175A of the CAA. After evaluating the redesignation requests submitted by Ohio and Indiana, EPA believes that the requests meet the redesignation criteria set forth in section 107(d)(3)(E) of the CAA. Therefore, EPA is approving the redesignation of the Ohio and Indiana portions of the Cincinnati-Hamilton area from nonattainment to attainment for the 1997 8-hour ozone NAAQS. EPA is also approving Ohio EPA's 2005 base year emissions inventory for the Ohio 
                    ( print page 26119)
                    portion of the Cincinnati-Hamilton area and IDEM's 2002 base year emissions inventory for Dearborn County as meeting the requirements of section 172(c)(3) of the CAA. Finally, EPA finds adequate and is approving the States' 2015 and 2020 MVEBs for Ohio and Indiana portions of the Cincinnati-Hamilton area. In accordance with 5 U.S.C. 553(d), EPA finds there is good cause for this action to become effective immediately upon publication. This is because a delayed effective date is unnecessary due to the nature of a redesignation to attainment, which relieves the area from certain CAA requirements that would otherwise apply to it. The immediate effective date for this action is authorized under both 5 U.S.C. 553(d)(1), which provides that rulemaking actions may become effective less than 30 days after publication if the rule “grants or recognizes an exemption or relieves a restriction,” and section 553(d)(3), which allows an effective date less than 30 days after publication “as otherwise provided by the agency for good cause found and published with the rule.” The purpose of the 30-day waiting period prescribed in section 553(d) is to give affected parties a reasonable time to adjust their behavior and prepare before the final rule takes effect. Today's rule, however, does not create any new regulatory requirements such that affected parties would need time to prepare before the rule takes effect. Rather, today's rule relieves the state of various requirements for this 8-hour ozone nonattainment area. For these reasons, EPA finds good cause under 5 U.S.C. 553(d)(3) for this action to become effective on the date of publication of this action. IV. Statutory and Executive Order Reviews Under the CAA, redesignation of an area to attainment and the accompanying approval of a maintenance plan under section 107(d)(3)(E) are actions that affect the status of a geographical area and do not impose any additional regulatory requirements on sources beyond those imposed by state law. A redesignation to attainment does not in and of itself create any new requirements, but rather results in the applicability of requirements contained in the CAA for areas that have been redesignated to attainment. Moreover, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. These actions do not impose additional requirements beyond those imposed by state law and the CAA. For that reason, these actions: Are not “significant regulatory actions” subject to review by the Office of Management and Budget underExecutive Order 12866 (58 FR 51735, October 4, 1993);
                Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 
                    *et seq.*);
                Are certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 
                    *et seq.*);
                Do 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);
                Do not have Federalism implications as specified inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Are not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Are not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001);
                Are not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
                Do not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, underExecutive Order 12898 (59 FR 7629, February 16, 1994). In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law. 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 action 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by July 12, 2010. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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. (
