According to a release from Duke Energy, approximately 5,000 gallons of fuel spilled into the Ohio River on Monday night.
The spill happened at about 11:15 p.m. Monday during a routine transfer of fuel oil at the W.C. Beckjord Station.
The release was stopped by 11:30 p.m, according to the company.
Local, state and environmental agencies, along with the Coast Guard were promptly notified. Northern Kentucky Water District and Greater Cincinnati Water Works also were notified to take appropriate action.
"We notified state and local authorities of the incident and have been working with them throughout the overnight hours," said Chuck Whitlock, Duke Energy president of Midwest Commercial Generation and vice president of gas operations. "We have cleanup crews on site that are identifying the appropriate actions that will be needed to remediate."
Beckjord Station is located in Clermont County, approximately 20 miles east of Cincinnati. Duke Energy owns 100 percent of units 1 through 5 (units 1 through 4 have already been retired), and 37.5 percent of unit 6. Dayton Power & Light owns 50 percent of unit 6 and American Electric Power owns 12.5 percent. The station also has four combustion turbine generating units which burn #2 fuel oil. The combustion turbine generating units are primarily used for generating electric during periods of high demand or emergency situations.
The station is dispatched into PJM. Duke Energy Ohio anticipates it will retire all six coal-fired units by Jan. 1, 2015.
