The Environmental Protection Agency (EPA) is taking final action to approve portions of the State Implementation Plan (SIP) submission, submitted by the State of Georgia, through the Georgia Department of Natural Resources, Environmental Protection Division (GA EPD), on March 25, 2013, to demonstrate that the State meets 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. GA EPD certified that the Georgia SIP contains provisions that ensure the 2010 1-hour NO<INF>2</INF> NAAQS is implemented, enforced, and maintained in Georgia. EPA has determined that portions of Georgia's infrastructure submission, submitted on March 25, 2013, addresses certain required infrastructure elements for the 2010 1-hour NO<INF>2</INF> NAAQS.
