EDEN, N.C. (AP) - Duke Energy says a pipe under a coal ash pond has broken releasing an unknown amount of coal ash into the Dan River in Rockingham County.
The utility said the pipe broke Sunday afternoon at the now closed Dan River Steam Station in Eden. Crews are working to get all the water out of the broken pipe.
Duke Energy says the dam holding back the water in the ash basin remains solid despite some erosion.
Engineers are trying to figure out how much ash and water made it into the Dan River, and Duke Energy promised to release those figures once the calculations are finished.
Environmental groups criticized Duke Energy for waiting a day to report the spill to the public and not immediately giving results of water quality tests.
