Duke Energy is now reporting 9,000 gallons of fuel spilled into the Ohio River August 18 at the W.C. Beckjord Station. The original estimate was about 5,000 gallons.

“We are pleased with the cleanup progress we’ve made and will continue to do further remediation as needed as a result of the spill,” said Chuck Whitlock, Duke Energy president of Midwest Commercial Generation and vice president of gas operations. “The collaboration of the different agencies during this cleanup has proven to be invaluable.”

Cleanup crews are monitoring the river and its banks, and are responding to any reports of residue or diesel product spotted in the water or on the shoreline, a release says. A handful of calls have been fielded through the Cleanup Hotline since Friday, with no significant findings. Anyone wanting to report additional fuel residue in the river or on its banks may call 855-645-8265.
