Özet

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of North Carolina for the purpose of establishing system-wide emission limitations from the North Carolina Clean Smokestacks Act (CSA) into the North Carolina SIP. On August 21, 2009, the State of North Carolina, through the North Carolina Department of Environment and Natural Resources (NC DENR), Division of Air Quality (DAQ), submitted an attainment demonstration for the Hickory-Morganton-Lenoir and Greensboro-Winston Salem-High Point 1997 fine particulate matter (PM 2.5 ) nonattainment area. That submittal included a request that the system-wide emission limitations from the North Carolina CSA be incorporated into the State's federally approved SIP. EPA has determined that the CSA portion of this SIP revision is approvable pursuant to the Clean Air Act (CAA or Act).
