Keystone Pipeline Spill Nearly Twice as Large as Initially Reported

Months after a Keystone Pipeline oil spill was cleaned up in South dakota, the company admits the spill was nearly twice as large as initially reported.

The spill happened in November 2017 near Amherst in Marshall County and Transcanada, the owner of the line that carries oil to Oklahoma and Texas reported the spill involved 210,000 gallons of oil.

But this week, the company confirmed the spill on farmland was actually 407,000 gallons of crude oil. The spill turned out to be the seventh-largest onshore oil spill since 2010 according to the U.S. Department of Transportation.

The pipeline is 2,600 in length and carries oil from Alberta, Canada to Cushing and to Illinois. Repairs were quickly made at the time and the line returned to normal operations within 12 days after the leak.
