RALEIGH, N.C. (AP) — North Carolina regulators have cited five more Duke Energy power plants for lacking required storm water permits after a pipe collapse at one of the company's coal ash dumps caused a massive spill, coating 70 miles of the Dan River in toxic sludge.
The state Department of Environment and Natural Resources said Monday that Charlotte-based Duke had been issued formal notices of violation for not having the needed permits, which are required to legally discharge rainwater draining from its plants into public waterways.
Two other violations were issued Friday against the Dan River Steam Station, site of the Feb. 2 spill. State regulators indicated they had been aware since at least 2010 that some Duke facilities lacked the required storm water permits, yet took no enforcement action until after last month's disaster.
Duke declined to comment.
