[44 Pa.B. 7243]
[Saturday, November 15, 2014]

 Particulate matter (PM) includes both solid and liquid particles suspended in the air. Fine particle pollution describes particulate matter that is less than or equal to 2.5 micrometers in diameter (PM2.5). PM2.5 concentrations above the Federal health-based standard pose a serious human health threat. With significant improvements in air quality in the Pittsburgh-Beaver Valley Area, this nonattainment area is monitoring attainment of the 1997 annual and the 2006 24-hour PM2.5 National Ambient Air Quality Standards (NAAQS). The Pittsburgh-Beaver Valley nonattainment area for the PM2.5 NAAQS includes Beaver, Butler, Washington and Westmoreland Counties and portions of Allegheny, Armstrong, Greene and Lawrence Counties.

 In accordance with applicable Federal Clean Air Act (CAA) (42 U.S.C.A. §§ 7401—7671q) requirements, the Department of Environmental Protection (Department) intends to submit a request to the United States Environmental Protection Agency (EPA) for redesignation of the area to attainment of the 1997 and 2006 PM2.5 NAAQS. The Department is seeking public comments on the Redesignation Request and a proposed revision to the State Implementation Plan (SIP) containing the 2007 comprehensive inventory as required under section 172(c)(3) of the CAA (42 U.S.C.A. § 7502(c)(3)) and a Maintenance Plan demonstrating that the area can maintain the 1997 annual and 2006 24-hour PM2.5 health-based NAAQS for at least 10 years following redesignation as required under section 175A(a) of the CAA (42 U.S.C.A. § 7505a(a)). Upon the EPA approval of the SIP revision, the Maintenance Plan will also establish new motor vehicle emission budgets for transportation conformity purposes.
