Description of the source (including control equipment). Please see the attachments for source or

 process flow diagram:

Edgecombe Power Station is a cogeneration plant which combusts bituminous coal in four (4) stoker-fired boilers, 

each rated at approximately 375 million Btu heat input per hour, to produce steam. A portion of the steam can be 

sold to an industrial host for use in their manufacturing process(s). Any steam not sold to an industrial host is used to 

drive a turbine-generator to provide electricity that is sold to an electric power cooperative. The boilers are traveling 

grate, overfeed stoker boilers manufactured by Combustion Engineering.
