The Keystone pipeline has halted operations following an oil spill into a creek in the United States state of Kansas. The pipeline carries more than 600,000 barrels of oil from Canada to the Texas Gulf Coast each day.
Canada-based TC Energy said in a press release that it shut down the pipeline on Wednesday night in response to a drop in pipeline pressure. The company has yet to offer information on the scale and cause of the spill.

“The system remains shut down as our crews actively respond and work to contain and recover the oil,” the release said.
The spill resulted in oil leaking into a creek in northeastern Kansas and the company has said they were using machinery to prevent the oil from moving further downstream. Pipelines have long spurred concerns about the destructive potential of oil spills.
Another pipeline previously proposed by TC, the Keystone XL pipeline, would have been 1,930 kilometres (1,200 miles) long and cut across US states such as Montana, South Dakota and Nebraska.
That proposal spurred strong opposition from advocates who said it would increase the chance of spills, undermine the rights of Indigenous communities and worsen climate change.
Former President Donald Trump approved a permit for the contentious project in 2017 but a court halted construction in 2018 before the permit was cancelled by President Joe Biden’s administration last year.
TC finally abandoned the effort in June 2021 but has since filed a claim seeking remuneration for losses it says it faced because of the cancellation.
The spill on Wednesday occurred several years after the Keystone pipeline leaked about 1.4m litres (383,000 gallons) of oil in eastern North Dakota in 2019.
As word of the shutdown spread on Wednesday, oil prices ticked upwards by about five percent.
“It’s something to keep an eye on, but not necessarily an immediate impact for now,” said Patrick De Haan, head of petroleum analysis at GasBuddy, which tracks gasoline prices, according to the Associated Press. “It could eventually impact oil supplies to refiners, which could be severe if it lasts more than a few days.”
In their statement, Keystone said their primary focus was the “health and safety of onsite staff and personnel, the surrounding community, and mitigating risk to the environment through the deployment of booms downstream as we work to contain and prevent further migration of the release”.
Previous Keystone spills have resulted in stoppages that lasted up to two weeks. However, analysts have noted that the current stoppage could possibly last longer because it involves a body of water.
