Keystone Pipeline leaks 210000 gallons of oil in South Dakota

TransCanada (NYSE:TRP) says it has shut down part of its Keystone pipeline after 5K barrels of oil leaked in South Dakota.

Crews shut down the Keystone pipeline at approximately 6 this morning.

According to a release, a drop in pressure was detected and the estimated volume of the leak is 5,000 barrels or 210,000 gallons.

Officials don't believe the leak affected any surface water bodies or threatened any drinking water systems from the spill onto agricultural land, said Brian Walsh, an environmental scientist manager at the South Dakota Department of Environment and Natural Resources, which has dispatched a staff member to the site.

The Keystone pipeline has leaked in South Dakota before, as recently as last spring.

The bill would also guarantee the right of parents to opt their children out of school classes that conflicted with their values. This gives the Smith bill an immediate advantage over its legislative rival, a bill penned by Liberal senator James Paterson.

TransCanada has indicated that the pipeline from Hardisty, Alberta, to Cushing, Okla., and to Wood River/Patoka, Ill., is expected to remain shut down.

Amherst is about 200 miles north of Sioux Falls, S.D., and about 25 miles from the state's border with North Dakota.

A proposed addition to the Keystone system, called Keystone XL, has been a political flashpoint in the United States in recent years.

Keystone carries crude from the oil sands in Canada to refineries in IL and Texas, and to a distribution center in Oklahoma. Federal regulators said an "anomaly" on a weld on the pipeline was to blame. The substance flowing through the Keystone pipeline is known as diluted bitumen, or "dilbit", because the bitumen (the crude oil itself) is so thick and sticky it must be diluted in order to effectively flow through the system. The timing of the incident is notable, for Nebraska's Public Service Commission shall soon consider a new TransCanada permit for the pipeline system's Keystone XL extension. The PSC will announce its long-awaited decision on the application Monday.
