CHARLOTTE, North Carolina — Duke Energy plans to store millions of tons of coal ash at lined on-site landfills at two retired North Carolina generating plants.
The utility announced Wednesday it is submitting plans for the landfills at its Dan River Station in Eden and at its Sutton Plant outside Wilmington.
Duke said the landfills will provide permanent storage for more than 6 million tons of coal ash. The company said they are in addition to plans to build off-site landfills to handle more than 3 million tons of ash from the plants.
Duke said the on-site landfills will have synthetic and natural barriers and the ash will be stored dry.
Last month state environmental officials fined Duke $25 million over pollution seeping into groundwater from unlined ash sites at the Sutton plant.
