Air Permit Number: 52007 Permitted Source ID/Name: Boilers 1 and 2 Combined in Common Stack 1 and 2 Permitted Maximum Process Rate: Two 834.5 MMBtu/Hr Boilers Max. Normal Operation Process Rate: Target Process Test Rate

Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The Dominion Generation, Mecklenburg Facility consists of two pulverized coal boilers, each with a scrubber, a fabric filter baghouse, and a turbine generator. The flue gases from the two boilers are exhausted through a common stack. Each boiler produces 600,000 lb/hr of steam at a coal feed rate of 26.33 tons/hr. Steam from the boilers is fed to a condensing turbine generator. The rated generator output is approximately 834.5 mmBtu/hr, or 64.6 MW per unit (129.2 MW for the plant) with a 25,000 lb/hr steam extraction. Industry/SCC/NAIS 221112
