Oil spilled into the Delaware River just south of the Commodore Barry Bridge. Crews are working to clean it up.
Crews worked through the night to contain a crude oil spill in the Delaware River.
Officials say crews were off-loading crude oil from a boat in the river around 1 p.m. on Monday when a line ruptured.
Officials with the National Response Center say an estimated 1,000 gallons of crude oil spilled into the Delaware River in Trainer, Delaware County near Monroe Energy LLC, located about a mile south of the Commodore Barry Bridge.
"A thousand gallons is a significant spill because when oil hits the water, it spreads out," said Tracy Carluccio of the Delaware Riverkeeper Network.
A response team arrived at the scene, using boom to contain the spread. Crews used skimmers and vacuums to remove the oil from the water.
"These things happen unfortunately all too often in the Delaware River watershed," Carluccio said. "We're a very big port."
A pollution response team from U.S. Coast Guard Sector Delaware Bay went to the scene to verify safe and thorough cleanup operations.
Monroe Energy is owned by Delta Air Lines. The company refines products ranging from jet fuel to gasoline.
Monroe Energy spokesman Adam Gattuso said that the specific cause of the spill remained under investigation and that "we will be looking closely at the role the extreme weather might have played."
