Approval and Promulgation of Air Quality Implementation Plan: Kentucky; Approval Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard for the Paducah Area

EPA is proposing to approve a revision to the Kentucky State Implementation Plan (SIP) concerning the maintenance plan addressing the 1997 8-hour ozone standard for the Paducah 8-hour ozone attainment area, which comprises Marshall County and a portion of Livingston County (hereafter referred to as the "Paducah Area"). This maintenance plan was submitted to EPA on May 27, 2008, by the Commonwealth of Kentucky, and ensures the continued attainment of the 1997 8-hour ozone national ambient air quality standard (NAAQS) through the year 2020. On July 15, 2009, the Commonwealth of Kentucky submitted supplemental information with updated emissions tables for this Area to reflect actual emissions. EPA proposes to find that this plan meets the statutory and regulatory requirements, and is consistent with EPA's guidance. EPA is proposing to approve the revisions to the Kentucky SIP, pursuant to Section 110 of the Clean Air Act (CAA). On March 12, 2008, EPA issued a revised ozone standard. The current action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for the Paducah Area under the 2008 standard will be addressed in the future.
