## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve the State Implementation Plan (SIP) submission, submitted by the State of North Carolina, through the North Carolina Department of Environmental Quality, Division of Air Quality (NCDAQ) on August 23, 2013, to demonstrate that the State meets certain 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 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. NCDAQ certified that the North Carolina SIP contains provisions that ensure the 2010 1-hour NO<INF>2</INF> NAAQS is implemented, enforced, and maintained in North Carolina. EPA has determined that North Carolina's infrastructure SIP submission, provided to EPA on August 23, 2013, satisfies certain required infrastructure elements for the 2010 1-hour NO<INF>2</INF> NAAQS.
