Approval and Promulgation of Implementation Plans Kentucky: Approval of Revisions to the State Implementation Plan

الملخص

EPA is proposing to approve a request submitted on May 25, 2007, by the Commonwealth of Kentucky (Kentucky), through the Kentucky Division for Air Quality (KDAQ), to remove the "Potentially hazardous matter or toxic substances" rule from the EPA-approved Kentucky State Implementation Plan (SIP). KDAQ requested that EPA remove this rule from the Kentucky SIP, because the rule is not related to the attainment and maintenance of the National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve this request and correct the Kentucky SIP by removing this rule from the SIP pursuant to section 110(k)(6) of the Clean Air Act (CAA).
