The North Carolina Department of Environment and Natural Resources said a crack in a Chatham County dam has been repaired by Duke Energy crews.

The agency last week approved Duke’s plan to repair a large crack that had opened in an earthen dam at the Cape Fear Steam Electric Station that holds back millions of tons of coal ash. The crack was reported on March 20.

Duke Energy reported no water leaked from the ash impoundment through the crack.

During the repair process, crews flattened the dam and stabilized it with a layer of geotextile fabric and riprap, DENR reported.

DENR said its officials will be working with Duke Energy on a long-term repair to the dam. DENR also said it’s requiring Duke Energy to provide documentation of repairs made to the dam by an engineer.

The structure is at the Cape Fear River plant, where North Carolina regulators said Duke illegally pumped 61 million gallons of contaminated water from a coal ash pit.

Cape Fear is rated by the Environmental Protection Agency as a high-hazard dam where a spill could cause catastrophic damage to nearby homes and threaten lives.
