Air Plan Approval; Reasonably Available Control Technology (RACT) Determinations for Case-by-Case Sources Under the 2008 8-Hour Ozone National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is proposing to approve multiple state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions were submitted by the Pennsylvania Department of Environmental Protection (PADEP) to establish and require reasonably available control technology (RACT) for ten major sources of volatile organic compounds (VOC) and/or nitrogen oxides (NO<INF>X</INF>) pursuant to the Commonwealth of Pennsylvania's conditionally approved RACT regulations. In this rulemaking action, EPA is proposing to approve source-specific (also referred to as ``case-by-case'') RACT determinations for ten major sources located in Allegheny County. These RACT evaluations were submitted to meet RACT requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS). This action is being taken under the Clean Air Act (CAA).
