An oil spill in a creek in northeastern 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 on Thursday estimated the spill on the Keystone system at about 14,000 barrels, or 588,000 gallons. It said the affected pipeline segment had been “isolated,” the oil had been contained at the site with booms, or barriers, and environmental monitoring had been set up, including around-the-clock air-quality monitoring. It did not say how the spill occurred.
After a drop in pressure on the pipeline that carries oil from Canada to the Texas Gulf Coast, the company said it shut down its Keystone system Wednesday night.
Oil spilled into a creek in Washington County, Kansas, about 150 miles (240 kilometers) northwest of Kansas City.
Zack Pistora, a lobbyist for the Sierra Club in Kansas, noted the spill in his state was larger than all of the 22 previous spills combined on the Keystone pipeline, which began operations in 2010.
“This is going to be months, maybe even years before we get the full handle on this disaster and know the extent of the damage and get it all cleaned up,” he said.
