Abstract
The Environmental Protection Agency (EPA) is taking action on a state implementation plan (SIP) revision submitted by the Commonwealth of Pennsylvania (Pennsylvania). This revision consists of regulatory amendments intended to meet certain reasonably available control technology (RACT) requirements under the 1997 and 2008 8-hour ozone national ambient air quality standards (NAAQS). EPA is approving most parts of the Pennsylvania SIP revision as meeting RACT requirements under the Clean Air Act (CAA), while conditionally approving certain provisions, based upon Pennsylvania's commitment to submit additional enforceable measures that meet RACT. This action is being taken in accordance with the requirements of the CAA.
