Keystone Pipeline Spills Over 200,000 Gallons Of Tar Sands
By Robinson Meyer for The Atlantic. South Dakota - The Keystone pipeline was temporarily shut down on Thursday, after leaking about 210,000 gallons of [tar sands] oil into Marshall County, South Dakota, during an early-morning spill.
TransCanada, the company which operates the pipeline, said it noticed a loss of pressure in Keystone at about 5:45 a.m. According to a company statement, workers had “completely isolated” the section and “activated emergency procedures” within 15 minutes.
Brian Walsh, a state environmental scientist, told the local station KSFY that TransCanada informed the South Dakota Department of Environment and Natural Resources about the spill by 10:30 a.m.
