Air Plan Approval; Kentucky; Louisville Miscellaneous Rule Revisions

On August 29, 2012, the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), submitted changes to the Kentucky State Implementation Plan (SIP) on behalf of the Louisville Metro Air Pollution Control District (District or Jefferson County). The Environmental Protection Agency (EPA) is approving several changes that modify the District's air quality regulations as incorporated into the SIP. The changes to the regulatory portion of the SIP that EPA is approving pertain to definitional changes, administrative amendments, open burning, standards of performance, and volatile organic compounds (VOCs). EPA is approving these changes because the Commonwealth and Jefferson County have demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).
