Approval and Promulgation of Implementation Plans; Kentucky Infrastructure Requirements for the 2008 Lead National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is proposing to approve the July 17, 2012, State Implementation Plan (SIP) submission, submitted by the Commonwealth of Kentucky, Energy and Environment Cabinet, Department for Environmental Protection, through the Kentucky Division for Air Quality (KY DAQ) for inclusion into the Kentucky SIP. This proposal pertains to the Clean Air Act (CAA or the Act) infrastructure requirements for the 2008 Lead national ambient air quality standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure SIP submission.'' KY DAQ certified that the Kentucky SIP contains provisions that ensure the 2008 Lead NAAQS is implemented, enforced, and maintained in Kentucky. With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, EPA is proposing to determine that Kentucky's infrastructure SIP submission, provided to EPA on July 17, 2012, satisfies the required infrastructure elements for the 2008 Lead NAAQS.
