The Keystone Pipeline Spills 210000 Gallons of Oil in South Dakota

A total of 210,000 gallons of oil leaked Thursday from the Keystone Pipeline in Marshall County, South Dakota, the pipeline's operator, TransCanada, said.

A leak and spill in southeastern South Dakota in April 2016 prompted a weeklong shutdown of the pipeline. "Some landowners are concerned about how an oil spill might harm their property and water supplies".

This is the largest Keystone oil spill to date in South Dakota, said Brian Walsh, a spokesman for the state's Department of Environment and Natural Resources.

TransCanada crews detected a drop in pressure at about 6 a.m. CT Thursday morning and shut down the pipeline. In addition, Reuters reports that a portion of the pipeline running from Alberta to Oklahoma and IL has been closed until further notice, yet the pipeline's southern leg remains unaffected and continues to operate.

TransCanada said at the time that the leak was the first detected on the pipeline since it began operating, though there had been leaks at pumping stations.

The leak occurred about 3 miles southeast of the community of Amherst.

Meanwhile, TransCanada has pitched Keystone XL, its proposed 830,000 barrel per day tar sands, in similar terms, citing similar technology and safety procedures.

The Keystone XL pipeline got federal USA approval in March when President Donald Trump overturned former President Barack Obama's rejection of the project in 2015. Federal regulators said an "anomaly" on a weld on the pipeline was to blame.

The conduit is not the controversial and long-delayed Keystone XL Pipeline which TransCanada is still shepherding through the approval process. 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.
