Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to determine that the Rome, Georgia, fine particulate (PM2.5) nonattainment area (hereafter referred to as “the Rome Area”) has attained the 1997 annual average PM2.5 National Ambient Air Quality Standards (NAAQS). The Rome Area is comprised of Floyd County in its entirety. This proposed clean data 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 1997 annual PM2.5 NAAQS. If EPA finalizes this proposed clean data 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 standard shall be suspended so long as the Area continues to attain the annual PM2.5 NAAQS.

I. What action is EPA taking?

EPA is proposing to determine that the Rome Area (comprised of Floyd County) has attaining data for the 1997 annual PM2.5 NAAQS.[1] The proposal 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.

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/m3) based on a 3-year average of annual mean PM2.5 concentrations. At that time, EPA also established a 24-hour NAAQS of 65 μg/m3. 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 Rome Area was designated nonattainment for the 1997 annual PM2.5 NAAQS. See 40 CFR 81.311.

On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual PM2.5 NAAQS at 15.0 μg/m3 based on a 3-year average of annual mean PM2.5 concentrations, and promulgated a 24-hour NAAQS of 35 μg/m3 based on a 3-year average of the 98th percentile of 24-hour concentrations. On November 13, 2009, EPA designated the Rome Area as attainment for the 2006 24-hour NAAQS (74 FR 58688). In that action, EPA also clarified the designations for the NAAQS promulgated in 1997, stating that the Rome Area was designated as nonattainment for the annual NAAQS but attainment for the 24-hour standard. Thus, today's action does not address attainment of either the 1997 or the 2006 24-hour NAAQS.

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

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 NAAQS. This rule, at 40 CFR 51.1004(c), specifies some of the regulatory consequences of attaining the NAAQS, as discussed below.

III. Does the Rome area meet the annual PM2.5 NAAQS?

A. Criteria

Today's rulemaking proposes that the Rome Area is attaining the 1997 annual PM2.5 NAAQS. The Rome Area is comprised of Floyd County in its entirety.

Under EPA regulations at 40 CFR 50.7, the annual primary and secondary PM2.5 NAAQS 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.

B. Rome Area Air Quality

EPA has reviewed the ambient air monitoring data for the Rome 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 following table provides the annual average concentrations averaged over 2007-2009 at the site in the Rome Area with at least 75 percent complete data in each quarter of each of those 3 years. Quarters 1 and 2 of 2008 had completeness of approximately 73 percent for site 13-115-0005, which is the only particulate matter monitoring site in this Area. Data substitution, as described in 40 CFR part 50, Appendix Start Printed Page 77597N, was used to make a complete record. In March 2009, 13-115-0005 was relocated to site 13-115-0003. The design value below is a combined monitor record. The 3-year average annual concentration for 2007-2009 on this table without data substitution is 13.3 μg/m3 and 14.6 μg/m3 with data substitution.

Table 1—Annual Average Concentrations in the Rome Area

CountySite No.Annual average concentration (μg/m3)
Without data substitutionFloyd13-115-000313.3
With data substitutionFloyd13-115-000314.6

The Rome Area is meeting the 1997 annual PM2.5 NAAQS both with and without data substitution. More generally, EPA believes that the Rome Area is now meeting the 1997 annual PM2.5 NAAQS.

Since few data are available for 2010, the 2007-2009 data represent the most recent available data for EPA to use in its assessment. On the basis of this review, EPA is proposing to determine that the Rome Area has attained the 1997 annual PM2.5 NAAQS.

EPA is soliciting public comments on its proposal to determine that the Rome Area has attained the 1997 annual PM2.5 NAAQS.

IV. What is the effect of this action?

If this proposed clean data determination is made final, the requirements for the Rome PM2.5 nonattainment Area to submit an attainment demonstration and associated RACM, a RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 annual PM2.5 NAAQS would be suspended for so long as the Area continues to attain the PM2.5 NAAQS. See 40 CFR 51.1004(c). Notably, as described below, any such determination would not be equivalent to the redesignation of the Area to attainment for the annual PM2.5 NAAQS.

If this proposed rulemaking is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the Federal Register, that the Area has violated the annual PM2.5 NAAQS, the basis for the suspension of the specific requirements would no longer exist for the Rome nonattainment Area, and the Area would thereafter have to address the applicable requirements. See 40 CFR 51.1004(c).

Finalizing this proposed action would not constitute a redesignation of the Area to attainment of the annual PM2.5 NAAQS under section 107(d)(3) of the Clean Air Act (CAA or Act). Further, finalizing this proposed action does not involve approving a maintenance plan for the Area as required under section 175A of the CAA, nor would it find that the Area has met all other requirements for redesignation. Even if EPA finalizes the proposed action, the designation status of the Rome 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.

This action is only a proposed clean data determination that the Rome Area has attained the 1997 annual PM2.5 NAAQS. Today's action does not address the 24-hour PM2.5 NAAQS.

If the Rome Area continues to monitor attainment of the annual PM2.5 NAAQS, the requirements for the Rome Area to submit an attainment demonstration and associated RACM, a RFP plan, contingency measures, and any other planning SIPs related to attainment of the annual PM2.5 NAAQS will remain suspended.

V. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act 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 proposed 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 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);
  • 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 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.
