2011-13269. Approval and Promulgation of Implementation Plans and Designations of Areas for Air Quality Planning Purposes; Alabama, Georgia, and Tennessee: Chattanooga; Determination of Attaining Data for the 1997 Annual Fine Particulate Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

EPA has determined that the Chattanooga, Tennessee-Georgia, fine particulate (PM_2.5) nonattainment area (hereafter referred to as “the Chattanooga Area” or “Area”) has attained the 1997 annual average PM_2.5 National Ambient Air Quality Standard (NAAQS). The Chattanooga Area is comprised of Hamilton County in Tennessee, Catoosa and Walker Counties in Georgia, and a portion of Jackson County in Alabama. This determination of attainment is based upon quality-assured and certified ambient air monitoring data for the 2007-2009 period showing that the Area has monitored attainment of the 1997 annual PM_2.5 NAAQS. The requirements for the Area to submit an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the standard shall be suspended so long as the Area continues to attain the 1997 annual PM_2.5 NAAQS.

DATES:

Effective Date: This final rule is effective on June 30, 2011.

I. What action is EPA taking?

EPA is determining that the Chattanooga Area (comprised Hamilton County in Tennessee, Catoosa and Walker Counties in Georgia, and a portion of Jackson County in Alabama) has attaining data for the 1997 annual PM_2.5 NAAQS. This determination is based upon quality assured, quality controlled and certified ambient air monitoring data that shows the Area has monitored attainment of the 1997 annual PM_2.5 NAAQS based on the 2007-2009 data.

Other specific requirements of the determination and the rationale for EPA's action are explained in the notice of proposed rulemaking (NPR) published on March 22, 2011 (76 FR 15895). For summary purposes, a monitor in Rossville did not meet data completeness requirements for 2007 due to monitor shut-down. Data substitution was used to determine the attainment status of the Rossville site. The Georgia Environmental Protection Division (GA EPD) developed a weight-of-evidence approach for an alternative method of data substitution. EPA determined that GA EPD successfully demonstrated a strong correlation between the PM_2.5 data from the Rossville site and two other sites in the Area. The annual design value for 2007-2009 for the Chattanooga Area is 12.7 μg/m³, at the Siskin Drive site (47-065-4002). The comment period closed on April 21, 2011. No comments were received in response to the NPR.

II. What is the effect of this action?

This final action, in accordance with 40 CFR 51.1004(c), suspends the requirements for this Area to submit attainment demonstrations, associated RACM, RFP plans, contingency measures, and other planning SIPs related to attainment of the 1997 annual PM_2.5 NAAQS as long as this Area continues to meet the 1997 annual PM_2.5 NAAQS. Finalizing this action does not constitute a redesignation of the Chattanooga Area to attainment for the 1997 annual PM_2.5 NAAQS under section 107(d)(3) of the Clean Air Act (CAA). Further, finalizing this action does not involve approving maintenance plans for the Area as required under section 175A of the CAA, nor does it involve a determination that the Area has met all requirements for a redesignation.

III. What is EPA's final action?

EPA is determining that the Chattanooga Area has attaining data for the 1997 annual PM_2.5 NAAQS. This determination is based upon quality assured, quality controlled, and certified ambient air monitoring data showing that this Area has monitored attainment of the 1997 annual PM_2.5 NAAQS during the period 2007-2009. This final action, in accordance with 40 CFR 51.1004(c), will suspend the requirements for this Area to submit attainment demonstrations, associated RACM, RFP plans, contingency measures, and other planning SIPs related to attainment of the 1997 annual PM_2.5 NAAQS as long as the Area continues to meet the 1997 annual PM_2.5 NAAQS. EPA is taking this final action because it is in accordance with the CAA and EPA policy and guidance.

IV. Statutory and Executive Order Reviews

This action makes a determination of attainment based on air quality, and will result in the suspension of certain federal requirements, and it will not impose additional requirements beyond those imposed by state law. For that reason, this 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 CAA; 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, this 1997 PM_2.5 clean NAAQS data determination for the Chattanooga Area 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 August 1, 2011. 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).)
