**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Final rule.

**SUMMARY :**  EPA is making two final determinations under the Clean Air Act (Act) regarding the 1997 annual fine particle (PM2.5 ) nonattainment area of Detroit-Ann Arbor, Michigan (Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne Counties) (Detroit-Ann Arbor area or area). First, EPA is determining that the Detroit-Ann Arbor area has attained the 1997 annual PM2.5 National Ambient Air Quality Standard (NAAQS). EPA made this determination of attainment based upon complete, quality-assured, and certified ambient air monitoring data for 2009–2011, showing that the area has monitored attainment of the 1997 annual PM 2.5 NAAQS. Preliminary data available for 2012 indicate continued attainment. Pursuant to EPA rule, this determination suspends the requirements for the Detroit-Ann Arbor area to submit an attainment demonstration, associated reasonably available control measures (RACM) to include reasonably available control technology (RACT), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the 1997 annual PM 2.5 NAAQS so long as the area continues to attain the PM 2.5 NAAQS. EPA is also determining, based on complete, quality-assured and certified monitoring data for the 2007–2010 monitoring period, that the Detroit-Ann Arbor area had attained the 1997 annual PM 2.5 NAAQS by the its attainment date of April 5, 2010.

### 66546 Federal Register / Vol. 77, No. 215 / Tuesday, November 6, 2012 / Rules and Regulations

**SUPPLEMENTARY INFORMATION :**  This supplementary information section is arranged as follows: I. What action is EPA taking? II. What is the effect of this action? III. Statutory and Executive Order Reviews I. What action is EPA taking?

In this action, EPA is making final determinations solely with respect to the 1997 annual PM 2.5 NAAQS. First, EPA is finalizing its proposed determination that the Detroit-Ann Arbor area has attained the 1997 annual PM 2.5 NAAQS, based upon complete, quality-assured, and certified ambient air monitoring data for 2009–2011. Preliminary data for 2012 indicate continued attainment. Second, pursuant to section 179(c) of the Act, EPA is finalizing the proposed determination that the Detroit-Ann Arbor area attained the 1997 annual PM 2.5 NAAQS by its attainment date, April 5, 2010.

On July 5, 2012 (77 FR 39659), EPA proposed these two determinations related to the 1997 annual PM 2.5 NAAQS. A discussion of the rationale for these determinations and their effects was included in the notice of proposed rulemaking. EPA received one supportive comment related to these proposed determinations which can be found in the docket. EPA received no adverse comments addressing these proposed determinations for the 1997 PM2.5 NAAQS.

In its July 5, 2012 notice, EPA also proposed to make a separate determination with respect to the Detroit-Ann Arbor area’s attainment of the 24-hour 2006 PM 2.5 standard. EPA is not finalizing its proposal with respect to the 2006 PM 2.5 standard here. Instead, EPA intends to address the attainment status of the Detroit-Ann Arbor area for the 2006 PM 2.5 standard in a future, separate rulemaking action.

II. What is the effect of this action?

Under the provisions of EPA’s PM 2.5 implementation rule (40 CFR 51.1004(c)), EPA’s final determination that the area has attained the 1997 annual PM2.5 standard, based on the most recent quality-assured and certified data, suspends the requirements for the State of Michigan to submit for the Detroit Ann-Arbor area an attainment demonstration and associated RACM (including RACT), a RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS for so long as the area continues to attain the 1997 annual PM2.5 NAAQS. If EPA subsequently determines, after notice and comment rulemaking, that this area violates the 1997 annual PM 2.5 NAAQS, the basis for the suspension of the specific requirements, set forth at 40 CFR 51.1004(c), would no longer exist and the area would thereafter have to address the pertinent requirements.

This action does not constitute a redesignation of the Detroit Ann-Arbor area to attainment of the 1997 annual PM2.5 NAAQS under section 107(d)(3) of the Act. Further, this action is not an EPA approval of a maintenance plan for the area as required under section 175A of the Act, nor a finding that the area has met all other requirements for redesignation. Even after a determination of attainment by EPA, thedesignation status of the Detroit AnnArbor area remains nonattainment for the 1997 annual PM 2.5 NAAQS until such time as EPA determines that the area meets the Act requirements for redesignation to attainment and takesaction to redesignate the Detroit AnnArbor area.

Pursuant to section 179(c)(1) of the Act, EPA is also determining that the Detroit-Ann Arbor area attained the 1997 annual PM 2.5 NAAQS by its attainment date of April 5, 2010. In finalizing this action, EPA has satisfied its obligation under section 179(c). III. Statutory and Executive Order Reviews

This final action makes attainment determinations of the Detroit area’s attainment of the 1997 PM 2.5 NAAQS based on air quality data and results in the suspension of certain Federal requirements and does not impose any additional requirements. For that reason, this final action:

• Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• Is 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. );

• 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);

• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• Is 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 Act; and

• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, these 1997 PM2.5 NAAQS attainment determinations do 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 Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by January 7, 2013. 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. (See section 307(b)(2).) List of Subjects in 40 CFR Part 52

**ACTION :**  Final rule.

**SUMMARY :**  EPA is approving the fine particulate matter (PM2.5 ) 2005 base year emissions inventory, a portion of the State Implementation Plan (SIP) revision submitted by the Michigan Department of Environmental Quality (MDEQ) on June 13, 2008. The emissions inventory is part of Michigan’s SIP revision that was submitted to meet the nonattainment requirements related to the state’s Detroit-Ann Arbor (Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne Counties) nonattainment area for the 1997 annual PM 2.5 national ambient air quality standards (NAAQS). This action is being taken pursuant to sections 110 and 172 of the Clean Air Act (CAA).

**DATES :**  This final rule is effective on December 6, 2012.

**SUPPLEMENTARY INFORMATION :**  Throughout this document whenever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, we mean EPA. This supplementary information section is arranged as follows: I. What action is EPA taking? II. Final Action III. Statutory and Executive Order Reviews I. What action is EPA taking?

On August 1, 2012 (77 FR 45532), EPA published a proposed rulemaking to approve Michigan’s PM 2.5 2005 baseyear emissions inventory for the DetroitAnn Arbor area. EPA did not receive any comments, adverse or otherwise, on the August 1, 2012, proposed rulemaking. Pursuant to section 110 and 172 of the CAA, EPA is now taking final action to approve the Detroit-Ann Arbor area PM 2.5 2005 base year emissions inventory as provided in EPA’s August 1, 2012, proposed rulemaking. A summary of the background for today’s final action is provided below. For more detail, please refer to EPA’s proposed rulemaking at 77 FR 45532.

Section 172(c)(3) of the CAA requires areas to submit a comprehensive, accurate, and current inventory from all sources of actual emissions of the relevant pollutant or pollutants in such area. Michigan selected 2005 as the base year for the emissions inventory per 40 CFR 51.1008(b). Emissions contained in Michigan’s SIP revision covered the general source categories of point sources, non-road mobile sources, area sources, marine, aircraft and rail, and on-road mobile sources. A detailed discussion of the emissions inventory and its development can be found in the August 1, 2012, proposal. EPA has reviewed Michigan’s Detroit-Ann Arbor PM 2.5 2005 base year emissions inventory and has determined that it is adequate for the purposes of meeting the section 172(c)(3) emissions inventory requirement. Further, EPA has made the determination that the emissions were developed consistent with the CAA, implementing regulations, and EPA guidance for emission inventories.

II. Final Action

EPA is taking final action to approve the PM 2.5 2005 base year emissions inventory portion of the SIP revision submitted by MDEQ on June 13, 2008, consistent with sections 110 and 172 of the CAA. III. Statutory and Executive Order Reviews

Under the CAA, 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. Accordingly, this final action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this final action:

• Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• Is certified as not having a significant economic impact on a substantial number of small entities
