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

The Environmental Protection Agency (EPA) is proposing to approve in part, and disapprove, the November 4, 2011, State Implementation Plan (SIP) submission, provided by the Alabama Department of Environmental Management (ADEM) for inclusion into the Alabama 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. ADEM certified that the Alabama SIP contains provisions that ensure the 2008 Lead NAAQS is implemented, enforced, and maintained in Alabama. With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, which EPA is proposing no action through this notice, and with the exception of the provisions respecting state boards, for which EPA is proposing disapproval, EPA is proposing to approve Alabama's infrastructure SIP submission provided to EPA on November 4, 2011, as satisfying the required infrastructure elements for the 2008 Lead NAAQS.
