An oil spill in a creek in north-eastern Kansas this week is the largest for an onshore crude pipeline in more than nine years and by far the biggest in the history of the Keystone pipeline, according to federal data.
Canada-based TC Energy estimated the spill on the Keystone system at about 14,000 barrels and said the affected pipeline segment had been “isolated” and the oil contained. It did not say how the spill occurred.
