Duke Energy says heavy rain of Florence has a slope to be deposited on the shaft of a coal deposit on a closed power plant in the near of the coast of North Carolina.
Duke spokeswoman Paige Sheehan said about 2,000 cubic yards (1,530 cubic meters) of ash were displaced in the L. V. Sutton Power Station outside of Wilmington, and that polluted runoff probably flowed into the plant cooling pond. The company is not yet established whether the weir which drains the lake was open or if the contamination may have flowed into the Cape Fear River.
Florence slammed into North Carolina as a major hurricane on Friday, dumping nearly three feet (1 meter) of rain and the swelling of the region the rivers in the midst of major flooding.
Sheehan, says the company has reported the incident to the state and federal regulators.
