# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Final rule.

# SUMMARY:

                        EPA is determining that the bi-state Louisville (Indiana and Kentucky) fine particle (PM2.5) nonattainment area has attained the 1997 annual average PM2.5                         National Ambient Air Quality Standard (NAAQS). This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2007-2009 period showing that the area has monitored attainment of the annual PM2.5                         NAAQS. Preliminary data for 2010 available to date are consistent with continued attainment. As a result of this determination, 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 standards shall be suspended for so long as the area continues to attain the annual PM2.5                         NAAQS.                    

# DATES:

This final rule is effective on March 9, 2011.

## I. What action is EPA taking?

                    EPA is determining that the Louisville PM2.5                     annual NAAQS nonattainment area (which includes Jefferson and Bullitt Counties in Kentucky and Clark and Floyd Counties and the Madison Township of Jefferson County in Indiana) has attained the 1997 annual PM2.5                     NAAQS. This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2007-2009 monitoring period that show that the area has monitored attainment of the 1997 annual PM2.5                     NAAQS. Preliminary data available for 2010 are consistent with continued attainment.                

## II. What is the background for this action?

                    On July 18, 1997 (62 FR 36852), EPA established an annual PM2.5                     NAAQS at 15.0 micrograms per cubic meter (μg/                          ( print page 12861)                        m3                    ) based on a three-year average of annual mean PM2.5                     concentrations. At that time, EPA also established a 24-hour standard of 65 μg/m3                     (today's action does not address the 24-hour standard). See 40 CFR 50.7. On January 5, 2005 (70 FR 944), EPA published its air quality designations and classifications for the 1997 PM2.5                     NAAQS based upon air quality monitoring data from those monitors for calendar years 2001-2003. These designations became effective on April 5, 2005. The Louisville area was designated nonattainment for the 1997 PM2.5                     NAAQS. See 40 CFR 81.315 (Indiana) and 40 CFR 81.318 (Kentucky).                

                    On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual PM2.5                     NAAQS at 15.0 μg/m3                     based on a three-year average of annual mean PM2.5                     concentrations, and promulgated a 24-hour standard of 35 μg/m3                     based on a three-year average of the 98th percentile of 24-hour concentrations. On November 13, 2009, EPA designated the Louisville area as attainment for the 2006 24-hour standard (74 FR 58688). In that action, EPA also clarified the designations for the NAAQS promulgated in 1997, stating that the Louisville area was designated as nonattainment for the annual standards but attainment for the 24-hour standards. Thus, today's action does not address attainment of either the 1997 or the 2006 24-hour standards.                

                    In response to legal challenges of the annual standards promulgated in 2006, the U.S. Court of Appeals for the District of Columbia Circuit (DC Circuit) remanded these standards to EPA for further consideration. See                     *American Farm Bureau Federation and National Pork Producers Council, et al.*                     v.                     *EPA,*                     559 F.3d 512 (D.C. Cir. 2009). However, given that the 1997 and 2006 annual standards are essentially identical, attainment of the 1997 annual standards would also indicate attainment of the remanded 2006 annual standards.                

                    On April 25, 2007 (72 FR 20664), EPA promulgated its PM2.5                     implementation rule, codified at 40 CFR part 51, subpart Z, in which the Agency provided guidance for state and tribal plans to implement the 1997 PM2.5                     standards. This rule, at 40 CFR 51.1004(c), specifies some of the regulatory consequences of attaining the standards, as discussed below.                

## III. What did EPA propose?

                    EPA proposed that the Louisville area (including portions in Indiana and Kentucky) has attained the 1997 PM2.5                     NAAQS. EPA published this proposed determination on September 14, 2010, at 75 FR 55725. Further details regarding the proposal are available in the proposed rule. EPA's proposed action provided a 30-day public comment period. We did not receive any comments.                

## IV. What does the most recent monitoring data show?

                    EPA examined monitoring data for 2010 that are available to date in the EPA Air Quality System (AQS) database, but not yet certified. While these data are insufficient to represent full year average concentrations, all sites within the area average below 15.0 μg/m3                     and thus the available data suggest that this area continues to attain the 1997 annual PM2.5                     NAAQS.                

## V. What is the effect of this action?

                    On the basis of this review, EPA has determined that the Louisville area has attained the 1997 annual PM2.5                     NAAQS based on complete, quality-assured and certified 2007-2009 data. Data available for 2010 that are in the EPA AQS database but not yet certified suggest that the area continues to attain the 1997 annual PM2.5                     NAAQS. As a result of this determination, under the provisions of EPA's PM2.5                     implementation rule (                    *see*40 CFR 51.1004(c)), the requirements for Indiana and Kentucky to submit attainment demonstrations and associated RACM, RFP plans, contingency measures, and any other planning SIPs related to attainment of the 1997 annual PM2.5                     NAAQS for the Louisville PM2.5                     nonattainment area are suspended for so long as the area continues to attain the 1997 annual PM2.5                     NAAQS. This suspension will continue until such time, if any, that EPA subsequently determines that the area has violated the 1997 annual PM2.5                     NAAQS.                

                    If EPA subsequently determines, after notice-and-comment rulemaking in the                     **Federal Register**                    , that the area has violated the 1997 annual PM2.5                     NAAQS, the basis for the suspension of the specific requirements, set forth at 40 CFR 51.1004(c), would no longer exist for the pertinent area, and EPA would take action to withdraw the determination and direct the pertinent area to address the suspended requirements.                

                    The determination that the air quality data show attainment of the 1997 annual PM2.5                     NAAQS is not equivalent to the redesignation of the area to attainment for the 1997 annual PM2.5                     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. The designation status of the area will 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 for that standard.                

## VI. When is this action effective?

                    EPA finds that there is good cause for this determination to become effective on the date of publication of this action in the                     **Federal Register**                    , because a delayed effective date is unnecessary due to the nature of the action. The expedited effective date for this action is authorized under both 5 U.S.C. 553(d)(1), which provides that rule actions may become effective less than 30 days after publication if the rule “grants or recognizes an exemption or relieves a restriction,” and 5 U.S.C. 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.” As noted above, this determination of attainment will result in a suspension of the requirements for the Louisville area to submit an attainment demonstration, a RFP plan, section 172(c)(9) contingency measures, and any other planning SIPs related to attainment of the 1997 annual PM2.5                     NAAQS for so long as the area continues to attain the PM2.5                     NAAQS. The suspension of these requirements is sufficient reason to allow an expedited effective date of this rule under 5 U.S.C. 553(d)(1). In addition, the suspension of the obligations of Indiana and Kentucky to make submissions for these requirements provides good cause to make this rule effective on the date of publication of this action in the                     **Federal Register**                    , pursuant to 5 U.S.C. 553(d)(3). The purpose of the 30-day waiting period prescribed in 5 U.S.C. 553(d) is to give affected parties a reasonable time to adjust their behavior and prepare before the final rule takes effect. Where, as here, the final rule suspends requirements rather than imposing obligations, affected parties, such as the Louisville area, do not need time to adjust and prepare before the rule takes effect.                

## VII. Statutory and Executive Order Reviews

                    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. For this reason, this action is not subject to                           ( print page 12862)    Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action makes a determination based on air quality data and results in the suspension of certain Federal requirements. 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.*). Because this rule makes a determination based on air quality data, and results in the suspension of certain Federal requirements, 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).                

This rule also does not have tribal applications 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). 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), because it merely makes a determination based on air quality data and results in the suspension of certain Federal requirements, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks” (62 FR 19885, April 23, 1997) because it determines that air quality in the affected area is meeting Federal standards.

                    The requirements of 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply because it would be inconsistent with applicable law for EPA, when determining the attainment status of an area, to use voluntary consensus standards in place of promulgated air quality standards and monitoring procedures to otherwise satisfy the provisions of the CAA. This rule does not impose an information collection burden under the provisions of the Paper Reduction Act of 1995 (44 U.S.C. 3501*et seq.*).                

Under Executive Order 12898, EPA finds that this rule, pertaining to the determination of attainment of the fine particle standards for the Louisville (Indiana and Kentucky) area, involves determination of attainment based on air quality data and will not have disproportionately high and adverse human health or environmental effects on any communities in the area, including minority and low-income communities.

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because there is no federally recognized Indian country located in the states, 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 these actions 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 rules in the                     **Federal Register**                    . A major rule cannot take effect until 60 days after it is published in the                     **Federal Register**                    . These actions are not “major rules” as defined by 5 U.S.C. 804(2).                

                    Under section 307(b)(1) of the CAA, petitions for judicial review of these actions must be filed in the United States Court of Appeals for the appropriate circuit by May 9, 2011. Filing a petition for reconsideration by the Administrator of these final rules 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. These actions may not be challenged later in proceedings to enforce its requirements. (                    *See*                     section 307(b)(2).)
