Duke Energy plans to submit permits to construct fully lined on-site landfills at the Dan River Steam Station in Eden, N.C., and the Sutton Plant in Wilmington, N.C. The landfills will be located on plant property and will provide a permanent storage solution for more than 6 million tons of coal ash at the two sites. The projects will also have contingency capacity for additional excavation at the sites, if needed. The proposed landfills are in addition to off-site solutions that Landfills at each site will feature multiple layers of synthetic and natural barriers. Coal ash will be stored dry in the landfills with additional layers of lining installed on top of the landfill - effectively containing the ash and separating it from surrounding soil and groundwater.
