An oil spill from TC Energy Corp.’s Keystone pipeline this week is on track to be one of the largest onshore crude disasters of the decade.

The pipeline carrying heavy oil from Canada to the US has so far leaked about 14,000 barrels in Kansas, TC Energy said Thursday. That’s the biggest spill in Keystone’s history and one of the top five largest onshore oil leaks since 2010, according to data from the Pipeline and Hazardous Materials Safety Agency. The total release could end up being larger.
