More than 380,000 gallons of crude oil spilled from the Keystone pipeline in North Dakota this week, according to a New York Times report, with state environmental regulators estimating about a half-acre of wetland was impacted by the incident.
The Hill reported that Karl Rockeman, the director of the state Department of Environmental Quality's division of water quality, said the leak has been contained.
Rockeman also said there are no homes in the vicinity of the spill and that the wetland affected is not a source of drinking water.
TC Energy, which owns the pipeline, said it was shut down after the leak was detected, also indicating an internal investigation is underway to determine the cause of the leak.
“We are establishing air quality, water and wildlife monitoring and will continue monitoring throughout the response,” the company said in a statement.
The Hill noted that a previous lead in the pipeline caused a spill near the border between North and South Dakota, sending more than 407,000 gallons of crude oil into the surrounding agricultural land.
