12 coal ash basins could be excavated in North Carolina

Duke Energy has suggested full excavation of an additional 12 coal ash basins in North Carolina.

The company recommends excavating five basins at the Cape Fear plant (Moncure), five basins at H.F. Lee plant (Goldsboro), one basin at W.H. Weatherspoon plant (Lumberton) and one inactive basin at the Cliffside thermal plant (Mooresboro). This would mean the company now has 24 Carolina basins that it is willing to close by removing ash from its current storage locations at each power plant.

The majority of the excavated ash is intended to be safely relocated to previously discussed lined structural fills in Chatham and Lee counties in North Carolina or permanently disposed in lined landfills.

“We’re making strong progress to protect groundwater and close ash basins, delivering on our commitment to safe, sustainable, long-term solutions,” said Lynn Good, Duke Energy’s President and CEO.

Closure options include an approach that consolidates the ash onsite, caps it with a durable and impermeable liner and protects groundwater. Thorough groundwater assessments, groundwater modelling and other site-specific engineering are all continually being carried out to inform closure options.

Good continued: “A blue ribbon national advisory board and independent engineers, scientists, and dedicated teams at Duke Energy are spending thousands of hours studying data, building enhanced groundwater and surface water protection programmes, and identifying closure options that protect people and the environment in a cost-effective manner.”

The proposals are subject to public input and approval by the North Carolina Department of Environment and Natural Resources and the North Carolina Coal Ash Management Commission.
