Duke Energy says outside engineers will finish assessing its coal ash ponds by May 31, following a February spill into the Dan River.
In a statement Wednesday that largely repeats what CEO Lynn Good wrote Gov. Pat McCrory on March 12, Duke said it will take a “disciplined, fact-based approach to evaluating long-term solutions for ash basins.”
Duke has said it will remove ash from ponds at its retired Dan River plant in Eden and the Riverbend power plant near Charlotte. It will continue moving ash from its Asheville plant to that city’s airport and accelerate closing the ponds at its Sutton plant in Wilmington.
Duke said it will consider retiring three units, at its Asheville and Cliffside plants, or convert them to a dry-ash handling system.
State environment Secretary John Skvarla has called that plan, outlined by Good earlier in the month, as inadequate for its lack of detail. McCrory has said the state wants Duke to move its ash away from water supplies like Charlotte’s Mountain Island Lake.
Apart from hiring the outside engineers, Duke added few new specifics Wednesday.
Duke said it has also started engineering work, to be finished by year’s end, on a “broad range of potential options” for remaining ash ponds. The company has 33 ponds at 14 active or retired power plants in North Carolina.
In a full-page ad in Sunday’s Observer, Good said Duke cares “deeply about getting this right.”
