EPA is approving revisions to the North Carolina State Implementation Plan (SIP) to allow the State air pollution control agency and the Forsyth County, North Carolina air pollution control agency to utilize exclusionary rules for the purpose of limiting potential to emit (PTE) criteria pollutants for certain source categories to less than the title V permitting major source thresholds. EPA is also approving under section 112(l) of the Clean Air Act several source-categories of the submitted regulations for limiting PTE of hazardous air pollutants (HAP) to less than title V permitting major source thresholds. These exclusionary rules allow facilities to compute potential emissions based on actual emissions or raw material usage for the following source categories: gasoline service stations and dispensing facilities; coating, solvent degreasing, and graphic arts operations; dry cleaning facilities, grain elevators, cotton gins, and emergency generators. On August 4, 1995, the State of North Carolina through the Department of Environment, Health, and Natural Resources (DEHNR) submitted a SIP revision fulfilling the requirements necessary to utilize exclusionary rules to limit PTE of air pollutants in a federally enforceable manner. On December 28, 1995, the Forsyth County Department of Environmental Affairs (FCDEA) through the DEHNR submitted a SIP revision fulfilling the requirements necessary to allow Forsyth County to utilize exclusionary rules to limit PTE of air pollutants in a federally enforceable manner. Forsyth County's SIP regulations are a verbatim adoption of the State of North Carolina exclusionary regulations.
