Summary

The Environmental Protection Agency (EPA) is proposing to approve in part and disapprove in part portions of the April 23, 2013, and December 9, 2015, update State Implementation Plan (SIP) submissions, submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), for inclusion into the Alabama SIP. This proposal pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2010 1-hour nitrogen dioxide (NO<INF>2</INF>) national ambient air quality standard (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 2010 1-hour NO<INF>2</INF> NAAQS is implemented, enforced, and maintained in Alabama. With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting, and visibility in other states, for 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 submissions provided to EPA on April 23, 2013, and updated on December 9, 2015, as satisfying the required infrastructure elements for the 2010 NO<INF>2</INF> NAAQS.
