Development and Implementation of a Quality Assurance Program for the TVA Kingston Ash Recovery Project

摘要

On December 22, 2008, a coal fly ash release occurred at the Tennessee Valley Authority’s (TVA’s) Kingston Fossil Plant (KIF), allowing a large amount of fly ash to escape into the adjacent waters of the Emory River. The plant is located in Roane County, Tennessee, near the town of Kingston. Ash produced by the combustion of coal for power generation is stored on site in containment areas including a former dredge cell. KIF generates 10 billion kilowatts of electricity per year-enough to supply electricity to approximately 670,000 homes. There are nine coal-fired generating units in operation at KIF and the plant consumes an average of 14,000 tons (12,698 metric tons) of coal per day.
