Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The Ebensburg Power Company is located in Ebensburg, Cambria County, Pennsylvania. A circulating fluidized bed boiler is the primary steam generating unit within the Ebensburg Power facility. The CFB boiler burns bituminous waste coal and operates on a continuous basis. The CFB boiler as a current capacity to produce 510 klbs/hr of steam at 1,500 psig at 955 degrees F. The CFB boiler is equipped with a limestone addition feature for sulfur dioxide emissions control and a baghouse for particulate emissions control. Flue gas emissions are discharged through the baghouse to the atmosphere by a vertical stack. Industry/SCC/NAIS 221112
