Heavy rainfall at Duke Energy’s Rogers Energy Complex in Mooresboro, North Carolina, US, caused stormwater from the site’s coal pile to overflow and reach the Broad River, the company said in a press release.
The overflow was identified during a routine inspection on 2 August. The inspection determined that stormwater had come into contact with the site’s coal pile. It did not, however, come into contact with the 7.8 million short t of coal ash that is held at the ponds.
The company’s initial estimates put the amount of stormwater reaching the river at between 15 000 and 50 000 thousand gal.
According to the company, the stormwater runoff has now stopped and steps have been taken to ensure the issue does not occur again. The North Carolina Department of Environmental Quality (DEQ) has been notified.
The DEQ said it was investigating the site and would take “appropriate enforcement action” after its review.
