Site description

Duke Energy's Marshall Steam Station began operating in 1965 on the northwestern shore of Lake Norman in Terrell, North Carolina. It is one of the largest Duke Energy plants in the Carolinas and can generate up to 2,090 MW of electricity per year. One active ash basin currently receives coal combustion waste at the site, and the Environmental Protection Agency classified it as having a significant-hazard dam. In August 2013, the State of North Carolina entered into a consent decree with Duke Energy regarding seeps and other un-permitted discharges to groundwater from the site.
