## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve in part and disapprove in part portions of the April 23, 2013, State Implementation Plan (SIP) submission, submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), for inclusion into the Alabama SIP. This final action pertains to the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2010 1-hour sulfur dioxide (SO<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 submission." ADEM certified that the Alabama SIP contains provisions that ensure the 2010 1-hour SO<INF>2</INF> NAAQS is implemented, enforced, and maintained in Alabama. EPA has determined that portions of Alabama's infrastructure SIP submission, provided to EPA on April 23, 2013, satisfy certain required infrastructure elements for the 2010 1-hour SO<INF>2</INF> NAAQS.
