About 2,000 gallons of airplane fuel spilled into the Potomac River near Reagan National Airport this morning.

Although flights haven’t been affected by the spill, a spokeswoman for the District Department of Energy & Environment tells City Desk that crews are working to clean it up while an investigation into the cause of the spill gets underway. “DOEE and other emergency response teams (multi-jurisdictional) were immediately on the scene and implemented a barrier which successfully contained the spill, which is currently being cleaned up by the responsible party’s contractor,” Julia Robey Christian writes in an email. “There’s no reason to believe there will be any long term damage to the river or related waterways.”

A spokesperson for the Metropolitan Washington Airports Authority, which oversees National, told the Washington Post that it was not currently known how big the spill was. It occurred toward the south of the airport.

Update 11:35 a.m.: In a follow-up email, the DOEE spokesperson adds: “DOEE has dispatched our Water Quality Division inspectors, who are actively monitoring the District’s shoreline and other sensitive receptors for any impacts by the spill. Again, because the spill was quickly contained, there’s no reason to believe this will have any further effect on the broader waterway or on District shores. We are merely in the field as a precautionary measure.”
