Canadian oil company TransCanada confirmed Thursday that more than 200,000 gallons of oil spilled from its Keystone pipeline in North Dakota, one of the primary concerns of those protesting its extension last year.
TransCanada said the spill was contained within 15 minutes. South Dakota's Department of Environment and Natural Resources wasn't notified of the leak until 11:30 a.m. Eastern, more than four hours after the leak was detected, according to department groundwater scientist Brian Walsh, who spoke with local ABC affiliate KSFY.
There have been no indications of water contamination at this point, but nearby residents remain concerned:
"There are a lot of lakes and streams and underground water aquifers that are near our reservation and on our reservation, but I don't know exactly where it spilled," [Dave] Flute chairman of South Dakota's [Sisseton Wahpeton Oyate] said. "I don't know if it's on cropland or range or pasture lands, but I know we have a lot of good fertile soil here, and the level of concern is high with the tribe and the tribal council."
Protesters had hoped to curb such spills by blocking the pipeline's extension, finding short-lived cooperation from the Obama administration last year.
[I]n early 2017, President Trump gave TransCanada a presidential permit to construct the Keystone XL pipeline, with a capacity for transporting 830,000 barrels of crude oil per day.
Last year, Trump promised that the Keystone pipeline would lead to no impact on the environment.
