The Environmental Protection Agency (EPA) is proposing to approve revisions to the Indiana State Implementation Plan (SIP) submitted by the Indiana Department of Environmental Management (IDEM) to EPA on January 27, 2016, and February 5, 2016, for parallel processing. The submittal consists of orders issued by the Commissioner of IDEM that require more stringent sulfur dioxide (SO<INF>2</INF>) emissions limits than those currently contained in the SIP for Vectren's A. B. Brown Generating Station ("A.B. Brown") and Indiana- Kentucky Electric Corporation's Clifty Creek Generating Station ("Clifty Creek"). IDEM submitted these limits to enable the areas near these generating stations to qualify for being designated "attainment" of the 2010 primary SO<INF>2</INF> National Ambient Air Quality Standards (NAAQS), a matter that will be addressed in a separate future rulemaking. EPA's approval of these revisions to the Indiana SIP would make the Commissioner's orders' SO<INF>2</INF> emissions limits federally enforceable.
