Summary

EPA is proposing to approve in part, and to conditionally approve or disapprove in part, the State Implementation Plan (SIP), submitted by the State of North Carolina, through the Department of Environment and Natural Resources (NC DENR), Division of Air Quality (DAQ), to demonstrate that the State meets the requirements of sections 110(a)(1) and (2) of the Clean Air Act (CAA or Act) for the 1997 8-hour ozone national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by the EPA, which is commonly referred to as an “infrastructure” SIP. DAQ certified that the North Carolina SIP contains provisions that ensure the 1997 8-hour ozone NAAQS are implemented, enforced, and maintained in North Carolina (hereafter referred to as “infrastructure submission”). With the exception of sub-element 110(a)(2)(E)(ii), EPA is proposing to determine that North Carolina's infrastructure submission, provided to EPA on December 12, 2007, and clarified in a subsequent submission submitted on June 20, 2008, addressed the required infrastructure elements for the 1997 8-hour ozone NAAQS.
