Trucks and workers started cleaning up the Keystone oil pipeline spill in rural North Dakota, though its cause and the project timing is unclear.
The pipeline ruptured Tuesday morning in southeastern North Dakota and was shut down within two minutes by an employee who heard a mechanical bang. An aerial photo released Wednesday shows a black, pondlike pool of oil suspended in a partially snowy field that’s traversed by tire tracks.
A farmer told The Associated Press he could smell the scent of crude oil, carried by the wind.
South Bow, a liquid pipelines business that manages the pipeline, estimated the spill’s volume at 3,500 barrels, or 147,000 gallons. Keystone’s entire system remains shut down
