Approval and Promulgation of Implementation Plans Kentucky: Tennessee Valley Authority Paradise Facility State Implementation Plan Revision

EPA is taking final action to approve a source specific State Implementation Plan (SIP) revision submitted on October 19, 2007, by the Commonwealth of Kentucky through the Kentucky Division for Air Quality (KDAQ). This SIP revision supercedes a previous source-specific revision approved by EPA on August 25, 1989, including an equivalency demonstration supporting the redistribution of sulfur dioxide (SO<INF>2</INF>) emissions from Tennessee Valley Authority's (TVA's) Paradise Steam Plant located in Muhlenburg County, Kentucky. The revision being approved now includes SO<INF>2</INF> limits that are more stringent than the current SIP-approved statewide SO<INF>2</INF> limits for electric generating units (EGUs). Consistent with Kentucky Administrative Regulations (KAR) approved into the SIP, affected facilities located in Muhlenberg County are subject to an SO<INF>2</INF> emission limit of 3.1 pounds per million British Thermal Units (lbs/mmBTU). The 3.1 lbs/mmBTU limit was approved by EPA on June 24, 1983, as part of Kentucky's control strategy for attaining and maintaining the primary and secondary SO<INF>2</INF> national ambient air quality standard (NAAQS) in Muhlenberg County. This current SIP action will approve a limit of 1.2 lbs/mmBTU for all three units with limited bypass emissions of 3.1 lbs/mmBTU for scrubber maintenance on Unit 3. This revision was proposed for approval on February 5, 2008, and no adverse comments were received.
