This supplementary information section is arranged as follows:

II. Summary of SIP Revision

IV. Statutory and Executive Order Reviews

I. Background

On July 18, 1997, EPA established an annual PM2.5 NAAQS at 15.0 micrograms per cubic meter (μg/m3) (hereafter referred to as “the 1997 annual PM2.5 NAAQS”), based on a 3-year average of annual mean PM2.5 concentrations (62 FR 38652). At that time, EPA also established a 24-hour standard of 65 μg/m3. See 40 CFR 50.7. The 1997 annual PM2.5 NAAQS were 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. On January 5, 2005, EPA published its air quality designations and classifications for the 1997 annual PM2.5 NAAQS based upon air quality monitoring data for calendar years 2001-2003 (70 FR 944). These designations became effective on April 5, 2005. On April 14, 2005, EPA promulgated a supplemental rule amending the initial designations (70 FR 19844), with the same effective date (April 5, 2005) at 70 FR 944. As a result of this supplemental rule, the Steubenville-Weirton Area was designated nonattainment for the 1997 annual PM2.5 NAAQS. The Steubenville-Weirton Area is comprised of Brooke County and Hancock County in West Virginia (the West Virginia portion), and Jefferson County in Ohio. See 40 CFR 81.336 (Ohio) and 40 CFR 81.349 (West Virginia).

On September 14, 2011 (76 FR 56641), EPA determined that the West Virginia portion of the Steubenville-Weirton Area had attained the 1997 annual PM2.5 NAAQS. That determination was based on complete, quality-assured, quality-controlled, and certified ambient air monitoring data for the 2007-2009 period showing that the entire Steubenville-Weirton Area had monitored attainment of the 1997 annual PM2.5 NAAQS. EPA also evaluated preliminary quality-assured data available to date for 2010. The September 14, 2011 determination suspended the requirements for West Virginia to submit, for the West Virginia portion of the Steubenville-Weirton Area, an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning SIP revisions related to attainment of the standard for so long as the Steubenville-Weirton Area continues to meet the 1997 annual PM2.5 NAAQS.

Section 172(c)(3) of the CAA requires states to submit a comprehensive, accurate, and current inventory of actual emissions for each nonattainment area. EPA's requirements for an emissions inventory for the PM2.5 NAAQS are set forth in 40 CFR 51.1008. This proposed rulemaking action is limited to the approval of the emissions inventory included in West Virginia's June 24, 2009 submittal for the West Virginia portion of the Steubenville-Weirton Area. A separate action will be taken on the remainder of the SIP submittal.

II. Summary of SIP Revision

The 2002 base year emission inventory submitted by WVDEP on June 24, 2009 for the West Virginia portion of the Steubenville-Weirton Area includes emissions estimates that cover the general source categories of point sources, area sources, on-road mobile sources, and non-road mobile sources. The pollutants that comprise the inventory are PM2.5, coarse particles (PM10), nitrogen oxides (NOX), volatile organic compounds (VOC), ammonia (NH3), and sulfur dioxide (SO2). EPA has reviewed the results, procedures and methodologies for the base year emissions inventory submitted by WVDEP. The year 2002 was selected by WVDEP as the base year for the emissions inventory per 40 CFR 51.1008(b). A discussion of the emissions inventory development as well as the emissions inventory for the West Virginia portion of the Steubenville-Weirton Area can be found in Appendix C of the June 24, 2009 SIP submittal. Table 1, below, provides a summary of the annual 2002 emissions of PM2.5, PM10, SO2, NOX, VOC, and NH3 for the June 24, 2009 West Virginia submittal.

The CAA section 172(c)(3) emissions inventory is developed by the incorporation of data from multiple sources. States were required to develop and submit to EPA a triennial emissions inventory according to the Consolidated Emissions Reporting Rule (CERR) for all source categories (i.e., point, area, nonroad mobile and on-road mobile). EPA's review and evaluation of the methods used for the emissions inventory submitted by West Virginia are found in the Technical Support Document dated August 12, 2010, available online at www.regulations.gov, Docket No. EPA-R03-OAR-2012-0369. EPA finds that the process used to develop this emissions inventory for the West Virginia portion of the Steubenville Weirton Area is adequate to meet the requirements of CAA section 172(c)(3), the implementing regulations, and EPA guidance for emission inventories.

III. Proposed Action

EPA is proposing to approve the 2002 base year emissions inventory portion of the SIP revision submitted by the State of West Virginia on June 24, 2009 for the West Virginia portion of the Steubenville-Weirton Area, as it meets the requirements of section 172(c)(3) of the CAA. EPA has made the determination that this action is consistent with section 110 of the CAA. EPA is soliciting public comments on the issues discussed in this document, which will be considered before taking final action.

IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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 CAA. 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 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, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this proposed rule, pertaining to the 2002 base year emissions inventory for the West Virginia portion of the Steubenville-Weirton Area for the West Virginia SIP, 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.
