Proposed State Implementation Plan Revision: 2011 Base Year Emissions Inventory for the Allentown-Bethlehem-Easton, Lancaster, Philadelphia-Wilmington-Atlantic City (Pennsylvania Portion), Pittsburgh-Beaver Valley, and Reading Nonattainment Areas for the 2008 8-Hour Ozone National Ambient Air Quality Standards Availability for Public Comment and Notice of Public Hearings On March 27, 2008, the U. S. Environmental Protection Agency (EPA) published a final rule establishing revised primary and secondary 8-hour ozone National Ambient Air Quality Standards (NAAQS) (73 FR 16436) of 75 parts per billion. Subsequently, EPA designated ozone nonattainment areas for the 2008 ozone NAAQS and classified 36 areas in the country including the Allentown-Bethlehem-Easton, Lancaster, Philadelphia-Wilmington-Atlantic City (Pennsylvania portion), Pittsburgh-Beaver Valley, and Reading as "marginal" nonattainment areas (77 FR 30088; May 21, 2012). The Department of Environmental Protection (Department or DEP) is seeking public comment on the proposed State Implementation Plan (SIP) mandated under Sections 172(c)(3) and 182(a)(1) of the Clean Air Act, 42 U.S.C. §§ 7502(c)(3) and 7511a(a)(1), which require the submission of "a comprehensive, accurate, current inventory of actual emissions from all sources of the relevant pollutant or pollutants in such area." This SIP revision contains the comprehensive 2011 Base Year Emissions Inventory for the previously mentioned nonattainment areas for the 2008 ozone NAAQS. The proposed SIP revision meets the requirements necessary for an approvable SIP revision, including a detailed explanation of the 2011 base year emissions inventory for stationary, area, nonroad, and mobile anthropogenic sources as well as biogenic sources in the areas in Pennsylvania that EPA designated as nonattainment for the 2008 ozone NAAQS. The proposed anthropogenic emissions were estimated for volatile organic compounds, oxides of nitrogen, and carbon monoxide for both annual and a typical ozone season day emissions. The final SIP revision will be submitted to the U.S. Environmental Protection Agency for approval. The proposed SIP revision is available in the Department's eLibrary at www.dep.state.pa.us (select ''Tools,'' then ''eLibrary,'' then ''Publications,'' then "Air Quality", then ''State Implementation Plans - SIP Revisions'') or through the contact person listed below.
