Part of the controversial Keystone XL pipeline was shut down Thursday after more than 200,000 gallons of oil leaked in South Dakota.
TransCanada, the Calgary-based company that operates the Canada-to-Texas line, reported the leak Thursday morning in a sparsely populated area in the northeastern part of the state.
In a statement, TransCanada said the pipeline was shut off from Hardisty,Alberta to Cushing, Oklahoma, and to Wood River and Patoka in Illinois. The southern leg of the system, which stretches to the Mississippi Gulf Coast, remains open.
The leak comes four days before Nebraska officials are scheduled to vote on whether to approve a 275-mile-long extension of the project through the state. State approval is needed after President Donald Trump revived the project, called Keystone XL, even though it had been rejected by the Obama administration.
