National Emission Standards for Hazardous Air Pollutants From the Portland Cement Manufacturing Industry and Standards of Performance for Portland Cement Plants
The Environmental Protection Agency (EPA or Agency) is denying in part and granting in part the petitions to reconsider the final revised National Emission Standards for Hazardous Air Pollutants emitted by the Portland Cement Industry and the New Source Performance Standards for Portland Cement Plants issued under sections 112(d) and 111(b) of the Clean Air Act, respectively. The EPA is also denying all requests that the EPA issue an administrative stay of the National Emission Standards for Hazardous Air Pollutants and the New Source Performance Standards.
Proposed Approval of Air Quality Implementation Plan; Ohio and West Virginia; Determinations of Attainment of the 1997 Annual Fine Particle Standard for Four Nonattainment Areas
EPA is proposing to make two determinations regarding the fine particle (PM2.5) nonattainment areas of Cleveland-Akron, Columbus, Dayton-Springfield, and Steubenville-Weirton (hereafter referred to as ``Areas''). First, EPA is proposing to determine that these Areas have attained the 1997 annual average PM2.5 National Ambient Air Quality Standard (NAAQS) under the Clean Air Act (CAA). 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 areas have monitored attainment of the annual PM2.5 NAAQS. EPA also evaluated incomplete data from this period from other monitors in the Cleveland- Akron area, as well as complete preliminary quality-assured data available to date for 2010. EPA believes these data support the determination that the Areas have attained the 1997 annual PM2.5 NAAQS. If this proposed determination is made final, the requirements for these Areas to submit an attainment demonstration, associated reasonably available control measures (RACM) to include reasonably available control technology (RACT), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to attainment of the 1997 annual PM2.5 NAAQS shall be suspended for so long as the Areas continue to attain the 1997 annual PM2.5 NAAQS. Second, EPA is also proposing to determine, based on quality-assured and certified monitoring data for the 2007-2009 monitoring period, that these Areas have attained the 1997 annual PM2.5 NAAQS by the applicable attainment date of April 5, 2010.

Delegation of Authority to the State of West Virginia To Implement and Enforce Additional or Revised National Emission Standards for Hazardous Air Pollutants and New Source Performance Standards
On January 5, 2011, EPA sent West Virginia a letter acknowledging that West Virginia's delegation of authority to implement and enforce NESHAP and NSPS had been updated, as provided for under previously approved delegation mechanisms. To inform regulated facilities and the public of West Virginia's updated delegation of authority to implement and enforce NESHAP and NSPS, EPA is making available a copy of EPA's letter to West Virginia through this notice.
