DEQ Submittals:

This document serves as a revision to the North Carolina SIP, submitted to the U.S. Environmental Protection Agency on September 3, 2014. The North Carolina Division of Air Quality (NCDAQ) believes the requirements of Section 110(l) of the Clean Air Act relative to repeal of the transportation facilities rules have been met. The NCDAQ concludes that repeal of the transportation facility rules does not interfere with the attainment of any applicable national ambient air quality standard (NAAQS). All three maintenance areas, Charlotte, Winston-Salem and Raleigh/Durham are well below the 8 hour carbon monoxide (CO) standard. The North Carolina limited maintenance plan for carbon monoxide includes a contingency plan based on a triggering event and mechanisms that will ensure the state continues to maintain the CO NAAQS.
