As with many coal burning plants, the W.S. Lee Station has coal ash basins and other combustion residuals stored onsite. There were two active ash basins, an inactive ash basin, an ash structural fill, and an ash fill totaling about 3.2 million tons of ash. A geotechnical consultant indicated in 2010 that the active basins pose a potential threat if the embankments were to fail. Duke energy said that it would excavate the inactive basin and the ash fill, remove the ash, and haul it to a landfill near
Homer, Georgia. The active basins and the structural landfill would be excavated and put in a lined landfill. Status of coal ash basin closure is available for all Duke Energy plants. ==References==
