An estimated 3,000 gallons of fuel spilled Friday at Cincinnati Municipal Lunken Airport.

The fuel spilled "as the result of a mishap during the refueling of a plane," wrote Cincinnati City Manager Patrick Duhaney in an email sent Saturday to City Council.

Duhaney called it a "considerable" spill, with some of the fuel flowing into a storm drain system.

However, a valve was closed, isolating the storm drains from the Little Miami River, Duhaney wrote.

"At this time there are no safety or environmental concerns," Duhaney added.

The Cincinnati Fire Department, Ohio Environmental Protection Agency and a spill response team contracted by the company that owns the plane were among the agencies that responded to the incident. Duhaney did not name the company in his email.
