 Environmental Protection Agency 40 CFR Part 52
[EPA-R04-OAR-2009-0561-200919; FRL-8965-8]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Proposed rule.
 SUMMARY: EPA is proposing to determine that the Greensboro-Winston Salem-High Point, North Carolina, (hereafter referred to as “Greensboro, North Carolina”) nonattainment area for the 1997 fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS) has attained the 1997 PM2.5
                         NAAQS. This proposed determination is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for the years 2006-2008 showing that this area has monitored attainment of the 1997 PM2.5
                         NAAQS. In addition, monitoring data thus far available, but not yet certified, in the EPA Air Quality System (AQS) database for 2009 show that this area continues to meet the 1997 PM2.5
                         NAAQS. If this proposed determination is made final, the requirement for the State of North Carolina 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 Plans (SIPs) related to attainment of the standard for the Greensboro, North Carolina, PM2.5
                         nonattainment area, shall be suspended. This requirement would remain suspended as long as this area continues to meet the 1997 PM2.5
                         NAAQS.

SUPPLEMENTARY INFORMATION: I. What Action Is EPA Taking? II. What Is the Effect of This Action? III. What Is the Background for This Action? IV. What Is EPA's Analysis of the Relevant Air Quality Data? V. Proposed Action VI. Statutory and Executive Order Reviews I. What Action Is EPA Taking? EPA is proposing to determine that the Greensboro, North Carolina, PM2.5
                     nonattainment area has attained the 1997 PM2.5
                     NAAQS. This determination is based upon complete, quality assured, quality controlled, and certified ambient air monitoring data for the years 2006-2008 showing that the area has monitored attainment of the 1997 PM2.5
                     NAAQS. In addition, monitoring data thus far available, but not yet certified, in the EPA AQS database for 2009, show that this area continues to meet the 1997 PM2.5
                     NAAQS. II. What Is the Effect of This Action? If this determination is made final, under the provisions of EPA's PM2.5
                     implementation rule (
                    *see*40 CFR 51.1004(c)), the requirement for the State of North Carolina to submit an attainment demonstration and associated RACM, RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5
                     NAAQS for the Greensboro, North Carolina, PM2.5
                     nonattainment area, shall be suspended. This requirement would remain suspended as long as this area continues to meet the 1997 PM2.5
                     NAAQS. As further discussed below, the proposed determination for the Greensboro, North Carolina, PM2.5
                     nonattainment area would: (1) Suspend the requirement to submit an attainment demonstration and associated RACM (including reasonably available control technologies), RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5
                     NAAQS; (2) continue until such time, if any, that EPA subsequently determines that the area has violated the 1997 PM2.5
                     NAAQS; (3) be separate from, and not influence or otherwise affect, any future designation determination or requirements for the Greensboro, North Carolina, area based on the 2006 PM2.5
                     NAAQS; and (4) remain in effect regardless of whether EPA designates this area as a nonattainment area for purposes of the 2006 PM2.5
                     NAAQS. Furthermore, as described below, any such final determination would not be equivalent to the redesignation of the area to attainment based on the 1997 PM2.5
                     NAAQS. If this rulemaking is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the 
                    **Federal Register**
                    , that the area has violated the 1997 PM2.5
                     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 pertinent requirements. The determination that EPA proposes with this 
                    **Federal Register**
                     notice is not equivalent to a redesignation of the area to attainment. This proposed action, if finalized, would not constitute a redesignation to attainment under section 107(d)(3) of the Clean Air Act (CAA) because we would not yet have an approved maintenance plan for the area as required under section 175A of the CAA nor a determination that the area has met the other requirements for redesignation. The designation status of the area would remain nonattainment for the 1997 PM2.5
                     NAAQS until such time as EPA determines that it meets the CAA requirements for redesignation to attainment. This proposed action, if finalized, is limited to a determination that the Greensboro, North Carolina, PM2.5
                     nonattainment area has attained the 1997 PM2.5
                     NAAQS. The 1997 PM2.5
                     NAAQS became effective on July 18, 1997 (62 FR 36852), and are set forth at 40 CFR 50.7. The 2006 PM2.5
                     NAAQS, which became effective on December 18, 2006 (71 FR 61144), are set forth at 40 CFR 50.13. EPA is currently in the process of making designation determinations, as required by CAA section 107(d)(1), for the 2006 PM2.5
                     NAAQS. EPA has not made any designation determination for the Greensboro, North Carolina, area based on the 2006 PM2.5
                     NAAQS. This proposed determination, and any final determination, will have no effect on, and is not related to, any future designation determination that EPA may make based on the 2006 PM2.5
                     NAAQS for the Greensboro, North Carolina, area. Conversely, any future designation determination of the Greensboro, North Carolina, area, based on the 2006 PM2.5
                     NAAQS, will not have any effect on the determination proposed by this notice. If this proposed determination is made final and the Greensboro, North Carolina, area continues to demonstrate attainment with the 1997 PM2.5
                     NAAQS, the requirement for the State of North Carolina to submit for the Greensboro, North Carolina, PM2.5
                     nonattainment area an attainment demonstration and associated RACM, RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5
                     NAAQS will remain suspended regardless of whether EPA designates this area as a nonattainment area for purposes of the 2006 PM2.5
                     NAAQS. Once the area is designated for the 2006 NAAQS, it will have to meet all applicable requirements for that designation.
                    ( print page 51251) III. What Is the Background for This Action? On July 18, 1997 (62 FR 36852), EPA established a health-based PM2.5
                     NAAQS at 15.0 micrograms per cubic meter (μg/m3
                    ) based on a 3-year average of annual mean PM2.5
                     concentrations, and a twenty-four hour standard of 65 μg/m3
                     based on a 3-year average of the 98th percentile of 24-hour concentrations. EPA established the standards based on significant evidence and numerous health studies demonstrating that serious health effects are associated with exposure to particulate matter. The process for designating areas following promulgation of a new or revised NAAQS is contained in section 107(d)(1) of the CAA. EPA and State air quality agencies initiated the monitoring process for the 1997 PM2.5
                     NAAQS in 1999 and began operating all air quality monitors by January 2001. On January 5, 2005, 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 (70 FR 944). These designations became effective on April 5, 2005. The Greensboro, North Carolina, area is comprised of Davidson County and Guilford County, North Carolina, and was designated nonattainment for the 1997 PM2.5
                     NAAQS (
                    *see*40 CFR part 81). IV. What Is EPA's Analysis of the Relevant Air Quality Data? EPA has reviewed the ambient air monitoring data for PM2.5, consistent with the requirements contained in 40 CFR part 50, as recorded in the EPA AQS database for the Greensboro, North Carolina, PM2.5
                     nonattainment area. On the basis of that review, EPA has concluded that this area attained the 1997 PM2.5
                     NAAQS during the 2006-2008 monitoring period. Under EPA regulations at 40 CFR 50.7: (1) The 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
                    . (2) The 24-hour primary and secondary PM2.5
                     standards are met when the 98th percentile 24-hour concentration, as determined in accordance with 40 CFR Part 50, Appendix N, is less than or equal to 65 μg/m3
                    . Table 1 shows the design values (the metrics calculated in accordance with 40 CFR part 50, appendix N, for determining compliance with the NAAQS) for the 1997 Annual PM2.5
                     NAAQS for the Greensboro, North Carolina, nonattainment area monitors for the years 2006-2008. Table 2 shows the design values for the 1997 24-hour PM2.5
                     NAAQS for these same monitors for the same 3-year period. Table 1—Design Value for Counties in the Greensboro, North Carolina Nonattainment Area for 1997 PM2.5

 EPA's review of these data indicates that the Greensboro, North Carolina, nonattainment area has met and continues to meet the 1997 PM2.5
                     NAAQS. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action. V. Proposed Action EPA is proposing to determine that the Greensboro, North Carolina, nonattainment area for the 1997 PM2.5
                     NAAQS has attained the 1997 PM2.5
                     NAAQS based on 2006-2008 monitoring data. As provided in 40 CFR 51.1004(c), if EPA finalizes this determination, it will suspend the requirements for the State of North Carolina to submit for this area an attainment demonstration and associated RACM, RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5
                     NAAQS as long as the area continues to attain the 1997 PM2.5
                     NAAQS. VI. Statutory and Executive Order Reviews This action proposes to make a determination based on air quality data, and would, if finalized, result in the suspension of certain Federal requirements. For that reason, this proposed action: Is not a “significant regulatory action” subject to review by the Office of Management and Budget underExecutive 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Is not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001);
                Is not subject to requirements of Section 12(d) of the National( print page 51252)
                    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, underExecutive Order 12898 (59 FR 7629, February 16, 1994). In addition, this 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.
