Description of the source (including control equipment). Please see the attachments for source or process flow diagram: Cogentrix Virginia Leasing Corporation is a cogeneration plant which combusts bituminous coal in six (6) stoker-fired boilers, each rated at approximately 200 million Btu heat input per hour, to produce steam. A portion of the steam is sold to an industrial host for use in their manufacturing process. The remainder of the steam is used to drive a turbine-generator to provide electricity that is sold to Virginia Power. The boilers are traveling grate, overfeed, stoker boilers manufactured by Foster Wheeler and are normally operated at full load, 24 hours per day, 7 days per week. Industry/SCC/NAIS221112
