AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to determine that the West Virginia portions of three nonattainment areas for the 1997 fine particulate (PM2.5) National Ambient Air Quality Standard (NAAQS) have clean data for the 1997 PM2.5 NAAQS. These are Berkeley County, part of the Hagerstown-Martinsburg MD-WV nonattainment area; Wood County, part of the Parkersburg-Marietta WV-OH nonattainment area; and Marshall County and Ohio County, part of the Wheeling WV-OH nonattainment area, hereinafter referred to in this notice as the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM2.5 nonattainment areas. This proposed determination is based upon quality assured, quality controlled, and certified ambient air monitoring data that show that these areas have monitored attainment of the 1997 PM2.5 NAAQS based on 2006-2008 data. In addition, quality controlled and quality assured monitoring data for 2009 that are available in the EPA Air Quality System (AQS) database, but not yet certified, show these areas continue to have clean data for the 1997 PM2.5 NAAQS. If this proposed determination is made final, the requirements for these areas to submit an attainment demonstration, 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 meet the 1997 PM2.5 NAAQS.

VI. Statutory and Executive Order Reviews

I. What Action Is EPA Taking?

EPA is proposing to determine that the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM2.5 nonattainment areas have clean data for the 1997 PM2.5 NAAQS. This determination is based upon quality assured, quality controlled, and certified ambient air monitoring data that show these areas have monitored attainment of the 1997 PM2.5 NAAQS based on 2006-2008 data. In addition, quality controlled and quality assured monitoring data for 2009 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 section 51.1004(c)), the requirements for the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM2.5 nonattainment areas to submit an attainment demonstration, 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 these areas continue to meet the 1997 PM2.5 NAAQS.

As further discussed below, the proposed determination would: (1) For the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM2.5 nonattainment areas, suspend the requirements to submit an attainment demonstration, associated reasonably available control measures (RACM) (including reasonably available control technologies (RACT)), a reasonable further progress (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 these areas have violated the 1997 PM2.5 NAAQS; (3) be separate from, and not influence or otherwise affect, any future designation determination or requirements for the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling areas based on the 2006 PM2.5 NAAQS; and (4) remain in effect regardless of whether EPA designates these areas as nonattainment areas 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 these areas have violated the 1997 PM2.5 NAAQS, the basis for the suspension of the specific requirements, set forth at 40 CFR section 51.1004(c), would no longer exist, and these areas would thereafter have to address the pertinent requirements.

EPA's determination that the air quality data for these areas shows clean data for the 1997 PM2.5 NAAQS, as proposed in this Federal Register notice, is not equivalent to the redesignation of the areas 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 these areas as required under section 175A of the CAA, nor a determination that these areas have met the other requirements for redesignation. The designation status of these areas would remain nonattainment for the 1997 PM2.5 NAAQS until such time as EPA determines that these areas meet the CAA requirements for redesignation to attainment.

This proposed action, if finalized, is limited to a determination that the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM2.5 nonattainment areas have clean data for the 1997 PM2.5 NAAQS. The 1997 PM2.5 NAAQS Start Printed Page 38156became effective on July 18, 1997 (62 FR 36852) and are set forth at 40 CFR section 50.7. The 2006 PM2.5 NAAQS, which became effective on December 18, 2006 (71 FR 61144) are set forth at 40 CFR section 50.13. At this point, 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 Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling areas 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 Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling areas. Conversely, any future designation determination of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling areas, 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 Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling nonattainment areas continue to demonstrate attainment with the 1997 PM2.5 NAAQS, the requirements for the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling nonattainment areas to submit an attainment demonstration, 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 (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 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 Hagerstown-Martinsburg nonattainment area (Berkeley County, WV and Washington County, MD), the Parkersburg-Marietta nonattainment area (Wood County, WV and Washington County, OH), and the Wheeling nonattainment area (Marshall County, WV, Ohio County, WV, and Belmont County, OH) were 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 Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM2.5 nonattainment areas from 2006 to the present time. On the basis of that review, EPA has concluded that these areas are meeting the 1997 PM2.5 NAAQS based on 2006-2008 data. In addition, quality controlled and quality assured monitoring data for 2009 that are available in the EPA AQS database, but not yet certified, show these areas continue to attain the 1997 PM2.5 NAAQS.

Under EPA regulations at 40 CFR Part 50, section 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.

Tables 1.a, 1.b, and 1.c show the 2006-2008 design values for the 1997 Annual PM2.5 NAAQS for the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling nonattainment area monitors, respectively. Table 2.a, 2.b, and 2.c show the 2006-2008 design values for the 1997 24-Hour PM2.5 NAAQS for these same respective monitors. All design values in the tables are in micrograms per cubic inch (μg/m3).

EPA's review of these data indicate that the Martinsburg-Hagerstown MD-WV, Parkersburg-Marietta WV-OH, and Wheeling WV-OH nonattainment areas have met and continue 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 West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling nonattainment areas have clean data for the 1997 PM2.5 NAAQS. As provided in 40 CFR section 51.1004(c), if EPA finalizes this determination, it would suspend the requirements for these areas to submit an attainment demonstration, 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 these areas continue to attain the 1997 PM2.5 NAAQS.

VI. Statutory and Executive Order Reviews

Under the Clean Air Act, 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 Clean Air Act. Accordingly, this action merely proposes to approve 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 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, this proposed determination that the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling nonattainment areas have clean data for the 1997 PM2.5 standard 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 Start Printed Page 38158it will not impose substantial direct costs on tribal governments or preempt tribal law.
