Crews are investigating an oil spill in the Ohio River that originated from Duke Energy's Beckjord Station in New Richmond.
Sally Thelen, Duke Energy spokeswoman, said fuel spilled into the river, but officials have not yet confirmed how much.
"There was a leak late last night. It was stopped within 10 to 15 minutes," she said. "We're waiting until the sun comes up to get a better estimate of what was discharged."
Several crews from Anderson Township launched from Coney Island at about 6 a.m. Tuesday, according to a dispatcher from Hamilton County. The spill originated in Clermont County.
Crews were dispatched to several areas Tuesday morning after reports of a strong chemical odors were reported.
Police reported a smell coming from the river near California Nature Preserve near 5400 Kellogg Road at about 6:15 p.m.
Another caller who lives in the 6600 block of Beechmont reported a strong chemical odor inside and outside his residence, and said his eyes were burning. It is unclear if that incident is related to the spill.
Waterworks has shut off water intake valves that may be affected, according to emergency communications.
Clean Harbors, a company based in Cincinnati that provides hazardous waste disposal, also responded to the scene.
