The Keystone Pipeline Spills 210000 Gallons of Oil in South Dakota

TransCanada said in a statement that their crews responded to a leak at their Amherst, South Dakota site on Thursday morning and shut down the pipeline after about 5,000 barrels, or 210,000 gallons had leaked.

The pipeline from Hardisty, Alberta, to Cushing, Oklahoma, and to Wood River and Patoka in IL, has been shut, while the southern leg of the system to the Gulf Coast remains operational, the company said.

The leak was detected after a drop in pressure in the operating system. In April 2016, TransCanada shut down the pipeline after a local resident reported seeing oil seeping to the surface in South Dakota.

The pipeline would transport oilsands oil from Alberta through Montana and South Dakota to Nebraska, where it would connect with existing pipelines that feed Texas Gulf Coast refineries. An estimated volume of 5,000 barrels, or 210,000 gallons, leaked.

While details are still emerging around this spill, we know it occurred in Marshall County on South Dakota's northern border.

When TransCanada first proposed Keystone I, the company promised a state-of-the-art pipeline which would "meet or exceed world-class safety and environmental standards".

The same pipeline leaked about 17,000 gallons a year ago near Freeman, South Dakota.

The company says that it is providing state and federal regulators "with accurate and confirmed information on an ongoing basis".

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. The PSC will announce its long-awaited decision on the application Monday.
