The U.S. Coast Guard says they were called in from Buffalo for an oil spill in the Oswego Harbor Wednesday.

They are joined by the New York Department of Environmental Conservation to monitor an oil sheen that was seen near Breitbeck Park and Oswego Harbor Power LLC facility’s dock. Officials with the DEC say the source of the spoll is believed to be the Oswego Harbor Generating Station.

The city has closed the lower trail of Breitbeck Park. Management from the Oswego Harbor Generating Station has closed off the affected area to prevent spread and has contracted agencies to help with the cleanup effort. 

“Clean water in Oswego Harbor and Lake Ontario are critically important to our residents and wildlife.” Oswego Mayor Billy Barlow said in response to the spill. “We will do our part to ensure that the oil spread is limited and that as much of the fuel that can be captured is.”
