Summary

The Environmental Protection Agency (EPA) is proposing to approve portions of the State Implementation Plan (SIP) submission, submitted by the State of North Carolina, through the North Carolina Department of Environment and Natural Resources (NC DENR), Division of Air Quality (NCDAQ) on August 23, 2013, for inclusion into the North Carolina 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 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 submission. 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 is proposing to find that portions of North Carolina's infrastructure SIP submission, provided to EPA on August 23, 2013, satisfy certain infrastructure elements for the 2010 1-hour NO<INF>2</INF> NAAQS.
