Approval and Promulgation of Air Quality Implementation Plans; Kentucky; Approval of Revisions to State Implementation Plan; Revised Format for Materials Being Incorporated by Reference for Jefferson County, Kentucky

EPA is approving revisions to the Jefferson County portion of the Kentucky State Implementation Plan (SIP). The revisions were adopted by the Air Pollution Control District of Jefferson County (APCDJC) and submitted to EPA on February 3, 1998; September 22, 1998; February 11, 1999; May 21, 1999; July 20, 1999; and September 22, 2000, by the Commonwealth of Kentucky (Commonwealth) through the Kentucky Natural Resources and Environmental Protection Cabinet (KNREPC). These submittals include miscellaneous rule revisions and the recodification of APCDJC regulations. EPA is also revising the format of 40 CFR part 52 for materials submitted by the Commonwealth that are incorporated by reference (IBR) into the Jefferson County portion of the Kentucky SIP. This format revision primarily affects the "Identification of plan" section of 40 CFR part 52, as well as the format of the SIP materials that will be available for public inspection at the Office of the Federal Register (OFR), the Air and Radiation Docket and Information Center located in Waterside Mall, Washington, DC, and the Regional Office. The sections of 40 CFR part 52 pertaining to provisions promulgated by EPA or State- submitted materials that are not subject to IBR remain unchanged.
