The Keystone pipeline released about 3,500 barrels of oil in southeastern North Dakota, the conduit’s owner said Tuesday, after it was shut in the morning because of a leak.
In a statement Tuesday evening, Canada-based South Bow said the Keystone pipeline system remained “shut down” after a crude oil leak near Fort Ransom, North Dakota. The preliminary spill number is equivalent to about 147,000 gallons of oil.
“The affected segment has been isolated, and we have contained the release,” South Bow spokesperson Solomiya Lyaskovska said in an email.
An earlier statement from the North Dakota Department of Environmental Quality said the pipeline was “immediately” shut following the discovery of a leak. The agency also said the release was confined to an agricultural field “located south of the associated pump station.” The North Dakota DEQ said there was a “malfunction” in the Keystone system.
