TransCanada shuts down Keystone oil pipeline after another leak

Crews cleaning up Keystone Pipeline leak in Marshall County

TransCanada pipeline leaks 210000 gallons of oil near SD, ND border

Workers took the Keystone oil pipeline offline on Thursday after it spilled 5,000 barrels of oil in rural South Dakota, officials said.

TransCanada says that expects the pipeline to remain shut down as the company responds to the leak.

The company said that crews shut down the pipeline Thursday morning after a drop in pressure was detected resulting from an oil leak that's under investigation.

At least 210,000 gallons of crude oil derived from oil sands-a thicker, sticker type of oil than conventional crude-spilled from the pipeline into an agricultural area, according to South Dakota's environment and natural resources agency. State regulators have already granted construction permits for the pipeline. An estimated volume of 5,000 barrels, or 210,000 gallons, leaked.


The pipeline transports crude from Alberta, Canada, to refineries in IL and Oklahoma, passing through the eastern Dakotas, Nebraska, Kansas and Missouri.

While details are still emerging around this spill, we know it occurred in Marshall County on South Dakota's northern border. That new proposed pipeline would begin in Hardisty, Alberta, and extend south to Steele City, Neb., crossing through Montana, a thin slice of far southeast North Dakota, and then run through western and central South Dakota into Nebraska.

President Donald Trump issued a federal permit for the project in March.

TransCanada is seeking approval from the Nebraska Public Service Commission for the final section of a second pipeline project, the Keystone XL. Based on the safety record of Keystone I, Nebraska's PSC should carefully consider the impacts of TransCanada's much larger Keystone XL pipeline as it weighs its decision on Monday.
