Air Plan Approval; New York; Athens Generating Plant

The Environmental Protection Agency (EPA) is approving a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a Source-specific SIP (SSSIP) revision for the Athens Generating Plant, located at 9300 US Route 9 West, Athens, NY 12015 (Athens or the Facility). In accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS, the EPA finds that the control options in New York's SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to Oxides of Nitrogen (NO X ) emissions from the relevant Facility sources, which are identified as three combined-cycle Westinghouse model 501G combustion turbines with associated heat recovery steam generators and steam turbines (identified as Emission Units U-00001, U-00002, and U-00003 in the Facility's Title V permit and New York's submission). This action is being taken in accordance with the requirements of the Clean Air Act (CAA).
