Air Quality Plans; Kentucky; Infrastructure Requirements for the 2010 Sulfur Dioxide National Ambient Air Quality Standard

The Environmental Protection Agency (EPA) is taking final action to approve portions of the 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 (KDAQ), on April 26, 2013, for inclusion into the Kentucky 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." KDAQ certified that the Kentucky SIP contains provisions that ensure the 2010 1-hour SO<INF>2</INF> NAAQS is implemented, enforced, and maintained in Kentucky. EPA has determined that Kentucky's infrastructure SIP submission, provided to EPA on April 26, 2013, satisfies certain required infrastructure elements for the 2010 1-hour SO<INF>2</INF> NAAQS.
