## Abstract

The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted under cover letters dated December 21, 2016, and August 25, 2017, by the Commonwealth of Kentucky, through the Energy and Environment Cabinet (Cabinet). The SIP revisions were submitted by the Cabinet on behalf of the Louisville Metro Air Pollution Control District (LMAPCD or District) and make amendments to Jefferson County's regulations regarding definitions and the federally enforceable district origin operating permit (FEDOOP) program. EPA is approving the revisions modifying these regulations because the Agency believes they are consistent with the Clean Air Act (CAA or Act).
