TransCanada shut down part of its Keystone pipeline after an oil leak of about 5,000 barrels Thursday in Marshall County, South Dakota. This northern leg has been closed, said the company, but the southern leg of the system from Cushing to the Gulf Coast remains operational.
"TransCanada (TSX, NYSE: TRP) crews safely shut down its Keystone pipeline at approximately 6 a.m. CST (5 a.m. MST) after a drop in pressure was detected in its operating system resulting from an oil leak that is under investigation", TransCanada said in a statement shortly after the spill.
Crews shut down the pipeline Thursday morning and officials are investigating the cause of the leak. It already had been approved by most of the states along the route.
The conduit is not the controversial and long-delayed Keystone XL Pipeline which TransCanada is still shepherding through the approval process.
The pipeline transports crude from Alberta, Canada, to refineries in IL and Oklahoma, passing through the eastern Dakotas, Nebraska, Kansas and Missouri. 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. TransCanada is providing state and federal regulators, including the Pipelines and Hazardous Materials Safety Administration and the National Response Center, with accurate and confirmed information on an ongoing basis. President Trump this year signed a presidential permit allowing the company to build the Keystone XL pipeline, which would transport as much as 830,000 barrels of crude oil a day from Alberta, Canada, to Nebraska, where it would join existing pipelines that feed refineries elsewhere in the United States.
