Approval and Promulgation of Air Quality Implementation Plans;
West Virginia; Determination of Attainment and Determination of Clean
Data for the Annual 1997 Fine Particle Standard for the Charleston Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
SUMMARY: EPA is proposing to make two determinations regarding the
Charleston, West Virginia fine particulate matter (PM2.5) nonattainment area (hereafter referred to as ``Charleston Area'' or
``Area''). First, EPA is proposing to determine that the Area has attained the 1997 annual average PM2.5National Ambient Air
Quality Standard (NAAQS). This proposed determination of attainment is based upon complete, quality-assured, and certified ambient air monitoring data for the 2007-2009 period showing that the Charleston
Area has attained the 1997 annual PM2.5NAAQS and data available to date for 2010 in EPA's Air Quality System (AQS) database that show the area continues to attain. If EPA finalizes this proposed determination of attainment, the requirements for the Charleston Area to submit attainment demonstrations 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 for so long as the Area continues to attain the annual
PM2.5NAAQS. Second, EPA is also proposing to determine based on quality-assured and certified monitoring data for the 2007- 2009 monitoring period that the area has attained the 1997 annual
PM2.5NAAQS, by its applicable attainment date of April 5, 2010.
DATES: Comments must be received on or before August 15, 2011.

What actions is EPA taking?
In accordance with section 179(c)(1) of the Clean Air Act (CAA), 42
United States Code section 7509(c)(1), and 40 Code of Federal Register
(CFR) section 51.1004(c), EPA is proposing to determine that the
Charleston Area (composed of Kanawha and Putnam Counties) has attained the 1997 annual PM2.5NAAQS. This proposed action 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 PM2.5NAAQS and data available to date for 2010 that show the Area continues to attain. EPA is also proposing to determine, in accordance with EPA's
PM2.5Implementation Rule of April 25, 2007 (72 FR 20664), that the Charleston Area has attained the 1997 annual PM2.5
NAAQS by its applicable attainment date of April 5, 2010.
-
What is the background for these actions?
On July 18, 1997 (62 FR 36852), EPA established an annual
PM2.5NAAQS at 15.0 micrograms per cubic meter ([mu]g/m\3\) based on a 3-year average of annual mean PM2.5 concentrations (hereafter referred to as ``the annual PM2.5
NAAQS'' or ``the annual standard''). At that time, EPA also established a 24-hour standard of 65 [mu]g/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 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 Charleston Area was designated nonattainment for the annual 1997 PM2.5NAAQS during this designations process.
See 40 CFR 81.349 (West Virginia).
On October 17, 2006 (71 FR 61144), EPA retained the 1997 annual
PM2.5NAAQS at 15.0 [mu]g/m\3\ based on a 3-year average of annual mean PM2.5concentrations and promulgated a 24-hour standard of 35 [mu]g/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 Charleston Area as nonattainment for the 2006 24-hour standard (74 FR 58688). In that action, EPA also clarified the designations for the PM2.5
NAAQS promulgated in 1997, stating that the Charleston Area was designated as nonattainment for the annual standard and attainment for the 1997 24-hour standard. Today's action, however, does not address 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 Circuit 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.
On April 25, 2007 (72 FR 20664), EPA promulgated its
PM2.5implementation rule, codified at 40 CFR part 51, subpart Z, in which the Agency provided guidance for state and tribal plans to implement the 1997 PM2.5standard. This rule, at 40
CFR 51.1004(c), specifies some of the regulatory consequences of attaining the standard, as discussed below.
-
Has the Charleston Area attained the 1997 annual PM2.5 standard?
A. Criteria
Today's rulemaking proposes to approve that the Charleston Area has attained the 1997 annual PM2.5NAAQS, based on the most recent three years of quality-assured data and that the Area attained the 1997 annual PM2.5NAAQS by its applicable attainment date of April 5, 2010. Under EPA regulations at 40 CFR 50.7, the annual primary and secondary PM2.5standards 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 [micro]g/m\3\ at all relevant monitoring sites in the subject area.
B. Charleston Area Air Quality
EPA has determined that the PM2.5monitoring network for the Charleston Area is adequate. First, the number of
Page 41741
monitors in the Area meets the minimum regulatory requirements given in 40 CFR part 58 Appendix D. Second, the monitoring is in accordance with state monitoring plans that have been reviewed and approved by EPA.
Table 1 shows the design values (i.e., the 3-year average of annual mean PM2.5concentrations) for the 1997 annual
PM2.5NAAQS for the Charleston Area monitors for the years 2007-2009. All data considered have been quality-assured, certified, and recorded in AQS. The highest 3-year average annual concentration for 2007-2009 on this table was recorded in Kanawha County, West
Virginia at the South Charleston site 54-039-1005, recording a 3-year average annual concentration of 14.4 [mu]g/m\3\.
EPA's review of these data indicates that the Charleston Area has met the 1997 annual PM2.5NAAQS. Table 1 and the related discussion below show that based on EPA's analysis of data for 2007- 2009, the Area attained the 1997 annual PM2.5standard by its attainment date of April 5, 2010. In addition, Table 2 and the related discussion below, show that the Area continues to attain the standard based on data available to date for 2010.

C. How did EPA address the air quality in Charleston?
There are two monitors located in Kanawha County. There is a monitor located in Charleston and a monitor located in South
Charleston. There was a Guthrie site monitor also located in Kanawha
County that was shut down in 2007 because a carbon monitor for the
PM2.5chemical speciation network replaced it at its respective location. EPA data completeness requirements require at least 75 percent of the scheduled sampling days for each quarter have valid data. See 40 CFR part 50, Appendix N section 4.1(b). The use of less than complete data is subject to the approval of EPA, which may consider factors such as monitoring site closures/moves, monitoring diligence, and nearby concentrations in determining whether to use such data (40 CFR part 50, Appendix N, section 4.1(c)).
Determinations of attainment are based on three years of complete, quality-assured data. Nevertheless, any such assessment should consider additional quality-assured data, to the extent that quality-assured data exist. In accordance with Appendix N and standard EPA practice, this review of data is based on the three most recent years of complete data, generally 2007-2009. Quality-assured data are now available for 2010, which EPA used to compute preliminary design values. The
Charleston site has a preliminary 2008-2010 design value of 11.8 [mu]g/ m\3\ and the South Charleston site has a preliminary 2008-2010 design value of 13.2 [mu]g/m\3\. On the basis of this review, EPA is proposing to determine that the Charleston Area has attained the 1997 annual
PM2.5NAAQS and is soliciting public comments on its proposed determination.

D. Has the Charleston Area met the 1997 annual PM2.5air quality standard?
EPA has reviewed the ambient air monitoring data for
PM2.5, consistent with the requirements contained in 40 CFR part 50 and recorded the data in the EPA AQS database, for the
Charleston Area from 2007 through the present time.
On the basis of this review, EPA proposes to determine that the
Charleston Area has attained and continues to attain the 1997 annual
PM2.5NAAQS based on the quality-assured data for the 2007- 2009 period and preliminary data for the 2008-2010 monitoring period.
In addition, based on EPA's review of the data for 2007-2009 and in accordance with section 179(c)(1) of the CAA and EPA's regulations, EPA proposes to determine that the Charleston Area attained the 1997 annual
PM2.5NAAQS by its applicable attainment date of April 5, 2010.
-
What is the effect of these actions?
If EPA's proposed determination of attainment, based on the most recent three years of quality-assured data is made final, the requirements for the Charleston Area to submit attainment demonstrations and associated RACM, a RFP plan, contingency measures, and any other planning SIPs related to attainment of the 1997 annual
PM2.5NAAQS would be suspended for so long as the Charleston
Area continues to attain the 1997 annual PM2.5NAAQS. See 40
CFR 51.1004(c). Notably, as described below, any such determination would not be equivalent to the redesignation of the Charleston Area to attainment for the 1997 annual PM2.5NAAQS.
If this proposed determination of attainment is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the
Federal Register, that the Area has violated the 1997 annual
PM2.5NAAQS, the basis for the suspension of the specific requirements would no longer exist for the Charleston 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 1997 annual
PM2.5NAAQS under section 107(d)(3) of the CAA. Further, finalizing this proposed action does not involve approving maintenance plans for the Area as required under section 175A of
Page 41742
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 Charleston Area would remain nonattainment for the 1997 annual PM2.5NAAQS until such time as EPA determines that the Area meets the CAA requirements for redesignation to attainment and takes action to redesignate the Charleston Area.
In addition, if EPA's separate and independent proposed determination that the Area has attained the 1997 annual
PM2.5standard by its applicable attainment date (April 5, 2010), is finalized, EPA will have met its requirement pursuant to section 179(c)(1) of the CAA to make a determination based on the
Area's air quality data as of the attainment date whether the Area attained the standard by that date. These two actions described above are proposed determinations regarding the Charleston Area's attainment only with respect to the 1997 annual PM2.5NAAQS. Today's actions do not address the 24-hour PM2.5NAAQS.
-
Statutory and Executive Order Reviews
These actions propose to make determinations of attainment based on air quality, and would, if finalized, result in the suspension of certain federal requirements, and it would not impose additional requirements beyond those imposed by state law. For that reason, these proposed actions:
Are not ``significant regulatory actions'' subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Are 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.);
Do 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);
Do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Are not economically significant regulatory actions based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
Are not significant regulatory actions subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Are 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
Do 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 1997 annual PM2.5NAAQS determinations for the Charleston Area 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.
