TransCanada's Keystone pipeline shut after 5000-barrel leak in US

As a result, crews shut down the Keystone pipeline at approximately 6 this morning.

In the release the company said, crews safely shut down the pipeline at around 5 a.m. after a drop in pressure was detected in the operating system from the oil leak.

Western Canada Select heavy blend crude for December delivery was trading at $14.50 below the West Texas Intermediate benchmark at late afternoon on Thursday, down slightly from $14.20 the day before.

TransCanada Corp.'s Keystone pipeline leaked an estimated 210,000 gallons of oil in northeastern South Dakota, the company and state regulators reported Thursday. It already had been approved by most of the states along the route.


Keystone carries crude from the oil sands in Canada to refineries in IL and Texas, and to a distribution center in Oklahoma.

TransCanada officials say roughly 5,000 barrels leaked 35 miles south of the Ludden pump station in Marshall County, S.D. The area was isolated within 15 minutes and emergency response procedures were activated.

The company says that it is providing state and federal regulators "with accurate and confirmed information on an ongoing basis". This is actually Keystone's third major spill in South Dakota, with the first being a 21,000 gallon tar sands spill which occurred in its first year of operation and a 16,800 gallon spill which happened last year.

The pipeline is a segment of the 2,687-mile TransCanada system that is set to also include the controversial proposed Keystone XL pipeline, which is promised to be the safest pipeline ever built in North America by the company. President Donald Trump reversed that decision swiftly after taking office, which placed the final permitting decision in the hands of Nebraska.
