Sources are reporting that the Keystone pipeline has ruptured and spilled 210,000 gallons of oil in Marshall County, South Dakota.

The pipeline was shut down Thursday by the operator, TransCanada, and so far there are no reports of danger to waterways or wildlife in the area.

The pipeline runs from Alberta, Canada down to Texas and the Gulf Coast refineries.

In April of 2016, there was a spill of 16,800 gallons in South Dakota.
