CINCINNATI (AP) -- Federal officials say most of a reddish-brown sheen from thousands of gallons of fuel oil spilled into the Ohio River from a power plant has dissipated as cleanup estimated at hundreds of thousands of dollars a day continues.
The U.S. Environmental Protection Agency said Wednesday about 1,000 gallons of oil and contaminated water from the Duke Energy plant spill near Cincinnati has been recovered. The EPA says it expects cleanup to cost about $250,000 a day based on Duke's estimates. The Charlotte, North Carolina-based company is responsible for cleaning up the estimated 3,000 to 5,000 gallons spilled.
A Duke Energy spokeswoman says the spill at the plant apparently resulted from human error. She says officials believe a valve was left open during a transfer of oil among tanks.
