Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to determine pursuant to the Clean Air Act (CAA), that the bi-state Louisville, Kentucky-Indiana, fine particulate (PM2.5) nonattainment area (hereafter referred to as “the Louisville Area” or “the Area”) has attained the 1997 annual PM2.5 national ambient air quality standards (NAAQS) by its applicable attainment date of April 5, 2010. The determination of attainment was previously made by EPA on March 9, 2011, based on quality-assured and certified monitoring data for the 2007-2009 monitoring period. EPA is now proposing to find that the Louisville Area attained the 1997 annual PM2.5 NAAQS by its applicable attainment date. EPA is proposing this action because it is consistent with the CAA and its implementing regulations.

II. What is the background for this action?

III. What is the air quality in the Louisville Area for the 1997 annual PM2.5 NAAQS for the 2007-2009 monitoring period?

V. Statutory and Executive Order Reviews

I. What action is EPA taking?

Based on EPA's review of the quality-assured and certified monitoring data for 2007-2009, and in accordance with section 179(c)(1) of the CAA and EPA's regulations, EPA proposes to determine that the Louisville Area has attained the 1997 annual PM2.5 NAAQS by the applicable attainment date of April 5, 2010. The Louisville Area is comprised of Jefferson County in Kentucky, and Clark, Floyd and a portion of Jefferson Counties in Indiana.

On March 9, 2011, EPA published a final rulemaking making a determination of attainment to suspend the requirements for the Louisville Area to submit an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency Start Printed Page 34936measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the 1997 annual PM2.5 NAAQS so long as the Area continues to attain the 1997 Annual PM2.5 NAAQS. See 76 FR 12860. Today's proposed action merely makes a determination that the Louisville Area has attained the 1997 annual PM2.5 NAAQS by its applicable attainment date. This action is not a re-proposal of the attainment determination to suspend the requirements for the Louisville Area to submit an attainment demonstration and associated RACM, a RFP plan, contingency measures, and other planning SIP revisions related to attainment of the standard. More information regarding the 1997 annual PM2.5 NAAQS and the Area's attainment of that NAAQS is available at 76 FR 12860 (March 9, 2011).

II. What is the background for this action?

As a nonattainment area for the 1997 annual PM2.5 NAAQS, the Louisville Area had an applicable attainment date of April 5, 2010 (based on 2007-2009 monitoring data). Pursuant to section 179(c) of the CAA, EPA is required to make a determination on whether the Area attained the standard by its applicable attainment date. Specifically, section 179(c)(1) of the CAA reads as follows: “As expeditiously as practicable after the applicable attainment date for any nonattainment area, but not later than 6 months after such date, the Administrator shall determine, based on the area's air quality as of the attainment date, whether the area attained the standard by that date.”

III. What is the air quality in the Louisville Area for the 1997 annual PM2.5 NAAQS for the 2007-2009 monitoring period?

Under EPA regulations at 40 CFR 50.7, the 1997 annual primary and secondary PM2.5 standards are met when the annual arithmetic mean concentration, as determined in accordance with 40 CFR part 50, Appendix N, is less than or equal to 15.0 μg/m3 at all relevant monitoring sites in the subject area.

EPA reviewed the ambient air monitoring data for the Louisville Area in accordance with the provisions of 40 CFR part 50, Appendix N. All data considered have been quality-assured, certified, and recorded in EPA's Air Quality System database. This review addresses air quality data collected in the 3-year period from 2007-2009. The 3-year period from 2007-2009 is the period EPA must consider for areas that had an applicable attainment date of April 5, 2010.

As shown above in Table 1, during the 2007-2009 design period, the Louisville Area met the 1997 annual PM2.5 NAAQS. The official annual design value for the Louisville Area for the 2007-2009 period is 14.6 μg/m3. More detailed information on the monitoring data for the Louisville Area during the 2007-2009 design period is provided in EPA's March 9, 2011, final rulemaking to approve the clean data determination for the Louisville Area for the 1997 annual PM2.5 NAAQS. See 76 FR 12860.

IV. What is the proposed action, and what is the effect of this action?

This action is a proposed determination that the Louisville Area has attained the 1997 annual PM2.5 NAAQS by its applicable attainment date of April 5, 2010, consistent with the CAA section 179(c)(1). Finalizing this proposed action would not constitute a redesignation of the Louisville Area to attainment of 1997 annual PM2.5 NAAQS under section 107(d)(3) of the CAA. Further, finalizing this proposed action does not involve approving a maintenance plan for the Louisville Area as required under section 175A of the CAA, nor would it find that the Louisville Area has met all other requirements for redesignation. Even if EPA finalizes today's proposed action, the designation status of the Louisville Area would remain nonattainment for the 1997 annual PM2.5 NAAQS until such time as EPA determines that the Area meets the CAA requirements for redesignation to attainment and takes action to redesignate the Area.

V. Statutory and Executive Order Reviews

This action proposes to make a determination of attainment based on air quality, and would not impose additional requirements beyond those imposed by State law. For that reason, this proposed 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);Start Printed Page 34937
  • 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 proposed 1997 annual average PM2.5 NAAQS data determination for the Louisville Area does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIPs are not approved to apply in Indian country located in the states, and EPA notes that it will not impose substantial direct costs on Tribal governments or preempt Tribal law.
