NEW ORLEANS — The U.S. Coast Guard said it responded to a fuel oil spill on the Mississippi River near Gramercy, Louisiana.

The Coast Guard in New Orleans said it received a report Thursday morning from the National Response Center of a discharge originating from Petroleum Fuel and Terminal Mt. Airy on the Mississippi River. The estimated discharge amount is 2,500 gallons (9,460 liters).

Officials said initial reports indicated the spill happened during a transfer of oil from the facility to a barge.

Eight boats with a combination of skimming packages, boom, and absorbents were deployed.
