An estimated 2,500 gallons of fuel oil spilled into the Mississippi River near Gramercy on Thursday morning, according to the U.S. Coast Guard. 

A news released says the spill was reported to the New Orleans sector of the Coast Guard's Incident Management Division from the National Response Center just before 8:30 a.m.

The spill originated from Petroleum Fuel and Terminal Mount Airy during a transfer of oil from the facility to a barge at mile marker 144.6 on the Mississippi River.

The Coast Guard conducted two overflights and deployed multiple teams to assess the impact of the spill. Eight boats with a combination of skimming packages, boom and absorbents have been deployed and the Center for Toxicology and Environmental Health LLC is conducting air monitoring. 

The Coast Guard, Louisiana Oil Spill Coordinators Office, Louisiana Department of Wildlife and Fisheries and Department of Environmental Quality are investigating the incident.
