[Federal Register: October 22, 2008 (Volume 73, Number 205)] [Proposed Rules] [Page 62945-62948] From the Federal Register Online via GPO Access [wais.access.gpo.gov] [DOCID:fr22oc08-27] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 52 [EPA-R03-OAR-2008-0736; FRL-8732-2] Approval and Promulgation of Air Quality Implementation Plans; The Metropolitan Washington Nonattainment Area; Determination of Attainment of the Fine Particle Standard AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: EPA is proposing to determine that the Metropolitan Washington, DC-MD-VA nonattainment area for the 1997 fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS) has attained the 1997 PM2.5 NAAQS. This proposed determination is based upon quality assured, quality controlled, and certified ambient air monitoring data that show that the area has monitored attainment of the 1997 PM2.5 NAAQS since the 2004-2006 monitoring period, and continues to monitor attainment of the standard based on 2005-2007 data. In addition, quality controlled and quality assured monitoring data for 2008 that are available in the EPA Air Quality System (AQS) database, but not yet certified, show this area continues to attain the 1997 PM2.5 NAAQS. If this proposed determination is made final, the requirements for this area to submit an attainment demonstration and associated reasonably available measures, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the standard shall be suspended for so long as the area continues to attain the 1997 PM2.5 NAAQS.

The following outline is provided to aid in locating information in this preamble. 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 Metropolitan Washington, DC- MD-VA PM2.5 nonattainment area has attained the 1997 PM2.5 NAAQS. This determination is based upon quality assured, quality controlled, and certified ambient air monitoring data that show the area has monitored attainment of the 1997 PM2.5 NAAQS since the 2004-2006 monitoring period, and monitoring data that continue to show attainment of the 1997 PM2.5 NAAQS based on the 2005-2007 data. In addition, quality controlled and quality assured monitoring data for 2008 that are available in the EPA AQS database, but not yet certified, show this area continues to attain 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 requirements for the Metropolitan Washington, DC-MD-VA PM2.5 nonattainment area to submit an attainment demonstration and associated reasonably available control measures, a reasonable further progress plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS would be suspended for so long as the area continues to attain the 1997 PM2.5 NAAQS. As further discussed below, the proposed determination would: (1) For the Metropolitan Washington, DC-MD-VA nonattainment area, suspend the requirements to submit an attainment demonstration and associated reasonably available control measures (RACM) (including reasonably available control technologies (RACT)), a reasonable further progress plan (RFP), 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 Metropolitan Washington, DC-MD-VA 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 the pertinent requirements. The determination that EPA proposes with this Federal Register notice, that the air quality data shows attainment of the 1997 PM2.5 NAAQS, is not equivalent to the 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 Metropolitan Washington, DC-MD-VA PM2.5 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 Metropolitan Washington, DC-MD-VA 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 Metropolitan Washington, DC-MD-VA area. Conversely, any future designation determination of the Metropolitan Washington, DC-MD-VA area, based on the 2006 PM2.5 NAAQS, will not have [[Page 62947]] any effect on the determination proposed by this notice. If this proposed determination is made final and the Metropolitan Washington, DC-MD-VA area continues to demonstrate attainment with the 1997 PM2.5 NAAQS, the requirements for the Metropolitan Washington, DC-MD-VA area to submit an attainment demonstration and associated reasonably available control measures, a reasonable further progress plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS would 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. 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 ([mu]g/ m3) based on a 3-year average of annual mean PM2.5 concentrations, and a twenty-four hour standard of 65 [mu]g/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 exposures 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 developed all air quality monitors by January 2001. 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 Metropolitan Washington, DC-MD-VA (Charles, Frederick, Montgomery, Prince George's, Alexandria, Arlington, Fairfax, Loudoun, Prince William, Falls Church, Manassas, Manassas Park, Fairfax City, and the District of Columbia) area 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 and recorded in the EPA AQS database for the Metropolitan Washington, DC-MD-VA PM2.5 nonattainment area from 2004 through the present time. On the basis of that review, EPA has concluded that this area attained the 1997 PM2.5 NAAQS since the 2004-2006 monitoring period, and continues to monitor attainment of the NAAQS based on 2005-2007 data. In addition, quality controlled and quality assured monitoring data for 2008 that are available in the EPA AQS database, but not yet certified, show this area continues to attain the 1997 PM2.5 NAAQS. Under EPA regulations at 40 CFR Part 50, Sec. 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 [mu]g/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 [mu]g/m3. Table 1 shows the design values for the 1997 Annual PM2.5 NAAQS for the Metropolitan Washington, DC-MD-VA nonattainment area monitors for the years 2004-2006 and 2005-2007. Table 2 shows the design values for the 1997 24-Hour PM2.5 NAAQS for these same monitors and the same 3-year periods.

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 Metropolitan Washington, DC- MD-VA nonattainment area for the 1997 PM2.5 NAAQS has attained the 1997 PM2.5 NAAQS and continues to attain the standard based on data through 2008. As provided in 40 CFR 51.1004(c), if EPA finalizes this determination, it would suspend the requirements for this area to submit an attainment demonstration and associated reasonably available control measures, a reasonable further progress plan, contingency measures, and any other planning SIPs related to attainment of the 1997 PM2.5 NAAQS so long as the area continues to attain the 1997 PM2.5 NAAQS. VI. Statutory and Executive Order Reviews Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed 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 Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action proposes to make a determination based on air quality data, and would, if finalized, result 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 proposes to make a determination based on air quality data, and would, if finalized, result 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 proposed 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 proposed 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 proposes to make a determination based on air quality data and would, if finalized, result 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 proposed rule also is not subject to Executive Order 13045 ``Protection of Children from Environmental Health Risks'' (62 FR 19885, April 23, 1997) because it proposes to determine that air quality in the affected area is meeting Federal standards. The requirements of section 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 proposed 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 District of Columbia, Maryland and Virginia's determination of attainment of the fine particle standard for the Metropolitan Washington, DC-MD-VA area, involves a proposed 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.
