Summary

EPA is proposing to make a determination that the Metropolitan Washington, District of Columbia-Maryland-Virginia (DC-MD-VA) and Martinsburg-Hagerstown, West Virginia-Maryland (WV-MD) fine particle (PM ^2.5 ) nonattainment areas (hereafter referred to as “Areas”) have attained the 1997 annual PM ^2.5 National Ambient Air Quality Standard (NAAQS) by the applicable attainment date of April 5, 2010. These determinations are based upon complete, quality-assured, and certified ambient air monitoring data for the 2007-2009 monitoring period. EPA is finding these Areas to be in attainment, in accordance with the requirements of the Clean Air Act (CAA).

Supplementary Information

Throughout this document, whenever “we,” “us,” or “our” is used, we mean EPA. This supplementary information section is arranged as follows: I. What is EPA proposing? II. What is the background of these actions? III. What is EPA's analysis of the relevant air quality data? IV. What are the effects of these actions? V. Statutory and Executive Order Reviews I. What is EPA proposing? In accordance with section 179(c)(1) of the CAA, EPA is proposing to determine that the Metropolitan Washington, DC-MD-VA PM ^2.5 nonattainment area and the Martinsburg-Hagerstown, WV-MD PM ^2.5 nonattainment area have attained the 1997 annual PM ^2.5 NAAQS by the applicable attainment date of April 5, 2010. The proposal is based upon complete, quality-assured, and certified ambient air monitoring data for the 2007-2009 monitoring period. II. What is the background for these actions? On July 18, 1997 (62 FR 36852), EPA established a health-based PM ^2.5 NAAQS at 15.0 micrograms per cubic meter (μg/m 3 ) based on a 3-year average of annual mean PM ^2.5 concentrations (hereafter referred to as “the annual PM ^2.5 NAAQS” or “the annual standard”). At that time, EPA also established a 24-hour standard of 65 μg/m 3 (the “1997 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 PM ^2.5 NAAQS based upon air quality monitoring data from those monitors for calendar years 2001-2003. These designations became effective on April 5, 2005. The Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD nonattainment areas were designated nonattainment for the 1997 PM ^2.5 NAAQS during this designations process. See 40 CFR part 81.309 (the District), 40 CFR 81.321 (Maryland), 40 CFR 81.347 (Virginia), and 40 CFR 81.349 (West Virginia). The Metropolitan Washington 1997 annual PM ^2.5 nonattainment area consists of the District of Columbia (the District), a Northern Virginia portion (Arlington, Fairfax, Loudoun, and Prince William Counties and the cities of Alexandria, Falls Church, Fairfax, Manassas, and Manassas Park), and Charles, Frederick, Montgomery, and Prince George's Counties in Maryland. The Martinsburg-Hagerstown 1997 annual PM ^2.5 nonattainment area consists of Washington County in Maryland and Berkley County in West Virginia. On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual PM ^2.5 NAAQS at 15 μg/m 3 based on a 3-year average of annual mean PM ^2.5 concentrations, and promulgated a 24-hour standard of 35 μg/m 3 based on a 3-year average of the 98th percentile of 24-hour concentrations (the “2006 24-hour standard”). On November 13, 2009, EPA designated the Martinsburg-Hagerstown, WV-MD and Metropolitan Washington, DC-MD-VA areas 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 these geographical Areas were designated as nonattainment for the annual standard, but attainment for the 1997 24-hour standard (40 CFR part 81.309 for the District, 40 CFR part 81.321 for Maryland, 40 CFR part 81.347 for Virginia, and 40 CFR part 81.349 for West Virginia). Today's action, however, does not address attainment designations of either the 1997 or the 2006 24-hour standard. 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 standard 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 standards are essentially identical, attainment of the 1997 annual standard would also indicate attainment of the remanded 2006 annual standard. EPA previously made clean data determinations related to the 1997 annual PM ^2.5 NAAQS for each of these Areas pursuant to 40 CFR 51.1004(c). Determinations were made for the Metropolitan Washington Area on January 12, 2009 (74 FR 1146) and for the Martinsburg-Hagerstown Area on November 20, 2009 (74 FR 60199). These clean data determinations remain in effect. Under CAA section 179(c), EPA is required to make a determination that a nonattainment area has attained by its attainment date, and publish that determination in the Federal Register . The determination of attainment is not equivalent to a redesignation, and the states must still meet the statutory requirements for redesignation in order for the Areas to be redesignated to attainment. Complete, quality-assured, and certified PM ^2.5 air quality monitoring data recorded in the EPA Air Quality System (AQS) database for 2007 through 2009, show that the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD nonattainment areas attained the 1997 annual PM ^2.5 NAAQS by their applicable attainment date of April 5, 2010. III. What is EPA's analysis of the relevant air quality data? EPA has reviewed the ambient air monitoring data for PM ^2.5 , consistent with the requirements contained in 40 CFR part 50 and recorded in the data in the EPA AQS database for the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD nonattainment areas for the monitoring period from 2007 through 2009. On the basis of that review, EPA has concluded that the Areas attained the 1997 annual PM ^2.5 NAAQS based on data for the 2007-2009 monitoring period. Under EPA regulations at 40 CFR 50.7, the annual primary and secondary PM ^2.5 standards are met when the annual arithmetic mean concentrations, as determined in accordance with 40 CFR part 50, appendix N, is less than or equal to 15.0 μg/m 3 , at all relevant monitoring sites. The values calculated in accordance with 40 CFR part 50, appendix N, are referred to as design values, and these values are used to determine if an area is attaining the PM ^2.5 NAAQS. According to the PM ^2.5 implementation rule, the attainment date for these Areas is April 5, 2010 and the monitoring data from 2007 through 2009 is used to determine if the Areas attained by April 5, 2010. Table 1 shows the annual PM ^2.5 design values for each monitor in the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD areas for the years 2007-2009. All 2007-2009 design values are below 15.0 μg/m 3 . Based on these data, the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD areas have attained the 1997 annual PM ^2.5 NAAQS by the attainment date. A detailed summary of EPA's rationale for proposing these determinations may be found in the Technical Support Document (TSD) for this action which is available on line at http://www.regulations.gov , Docket number EPA-R03-OAR-2011-0801.

IV. What are the effects of these actions? If EPA's proposed determination that the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD nonattainment areas have attained the 1997 annual PM ^2.5 standard by the applicable attainment date (April 5, 2010) is finalized, EPA will have met its requirement pursuant to section 179(c) of the CAA to make a determination based on the Areas' air quality data as of the attainment date that the Areas attained the standard by that date. The action described above is a proposed determination regarding the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD Areas' attainment of the 1997 annual PM ^2.5 NAAQS. Finalizing this proposed action would not constitute a redesignation of the Areas to attainment of the 1997 annual PM ^2.5 NAAQS under section 107(d)(3) of the CAA. Further, finalizing this proposed action does not involve approving maintenance plans for the Areas as required under section 175A of the CAA, nor would it find that the Areas have met all other requirements for redesignation. Even if EPA finalizes the proposed action, the designation status of the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD areas would remain nonattainment for the 1997 annual PM ^2.5 NAAQS until such time as EPA determines that the Areas meet the CAA requirements for redesignation to attainment and take action to redesignate the Metropolitan Washington, DC-MD-VA and the Martinsburg-Hagerstown, WV-MD areas. EPA is soliciting comment on the action discussed in this document. These comments will be considered before EPA takes final action. Please note that if EPA receives adverse comment on either of the proposed determinations described above and if that determination may be severed from the remainder of the final agency action, EPA may adopt as final these provisions of the final agency action that are not the subject of an adverse comment. V. Statutory and Executive Order Reviews This action proposes to make attainment determinations based on air quality data and would not, if finalized, result in the suspension of certain Federal requirements and would not impose any additional requirements. 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 Clean Air Act; 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, these proposed PM ^2.5 NAAQS attainment determinations for the Metropolitan Washington and Martinsburg-Hagerstown Areas, do 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.
