This Section is a summary of the Independent Engineers Review of Management Units for the Roxboro Steam Electric Plant (Roxboro). The Report was prepared by Paul C. Rizzo Associates, Inc. (RIZZO) for the United States Environmental Protection Agency (USEPA) under subcontract to Lockheed Martin. This Section summarizes the finding, assessments, conclusions, and recommendations of the Independent Engineer. The Roxboro Plant is a coal fired power plant located on the South side of Hyco Lake, an impoundment of the Hyco River, near Semora, Person County, North Carolina. The facility is located approximately 9 miles northwest of Roxboro, North Carolina, approximately 6.5 miles downstream of the Town of Roxboro's surface water supply intake, and is owned and operated by Progress Energy Carolinas, Inc. (PGN). Under normal operating conditions, byproducts of coal combustion including fly ash, bottom ash, boiler slag, flue gas emission control residuals, and other general wastewater products are sluiced into either the West Ash Pond storage basin south of the plant or into a wastewater treatment system. The waste water treatment system consists of a FGD Settling Pond and FGD Flush Pond constructed within the West Ash Pond for the treatment of the blow down steam from the FGD absorber units at the power plant.
