[Ed. – The best bet here would be sabotage. Pipeline leaks on this scale are by no means common in North America.]
Crews are working to clean up a pipeline leak that has spilled at least 210,000 gallons of oil in South Dakota.
Brian Walsh with the Department of Environment and Natural Resources tells KSFY News they were alerted to the leak at 10:30 a.m. Thursday morning by TransCanada.
The leak was in the Keystone Pipeline located in an agricultural area in Marshall County. There have been no reports of the oil entering any waterways or water systems at this time.
Walsh said 5,000 barrels of oil have leaked, and at 42 gallons a barrel, that totals 210,000 gallons of oil.
The pipeline has been shut off and the leak has been covered. An emergency response plan has been activated to get more staff and contractors to the site for clean up.
