TransCanada says 210,000 gallons of oil leaked from Keystone pipeline in South Dakot

Keystone Pipeline leaks 210,000 gallons of oil in South Dakota A total of 210,000 gallons of oil leaked Thursday from the Keystone Pipeline in South Dakota, the pipeline's operator, TransCanada, said. Crews shut down the pipeline Thursday morning, and officials are investigating the cause of the leak, which occurred about three miles southeast of the town of Amherst, said Brian Walsh, a spokesman for the state's Department of Environment and Natural Resources. This is the largest Keystone oil spill to date in South Dakota, Walsh said. The leak comes just days before Nebraska officials announce a decision on whether the proposed Keystone XL Pipeline, a sister project, can move forward. In April 2016, there was a 400-barrel release -- or 16,800 gallons -- with the majority of the oil cleanup completed in two months, Walsh said. About 5,000 barrels of oil spilled Thursday. It is a below-ground pipeline, but some oil has surfaced above ground to the grass," Walsh said. "It will be a few days until they can excavate and get in borings to see if there is groundwater contamination." There were no initial reports of the oil spill affecting waterways, water systems or wildlife, he said. The pipeline was shut down "within minutes" of the company discovering an irregularity, TransCanada said Friday. The spill has been controlled, the company said, with no further environmental impacts observed and no threat to public safety. TransCanada said it was working with state and federal agencies. he spill occurred in the same county as part of the Lake Traverse Reservation. The leak location is not on Sioux property, but it is adjacent to it and has historical value, said Dave Flute, tribal chairman for Sisseton Wahpeton Sioux Tribe. "We want to know how long is it going to take to dig this plume of contaminated soil and how can we be reassured, without a doubt, that it has not and will not seep into the aquifer," he said. Flute, along with the tribal emergency management director and the manager of the tribal office of environmental protection, arrived Friday morning at the staging area of the leak site to meet with representatives from TransCanada. Flute said he was out there to offer assistance and to understand the cause of the leak and the environmental impacts it might pose. "We want to find out, was there a crack in the pipe? We don't know. We want to get that information," Flute said. "More importantly, and to stay positive, they did clean up the site, they did contain it." Environmental activist group Greenpeace said the spill shows the new pipeline in Nebraska should not be approved. "The Nebraska Public Service Commission needs to take a close look at this spill," said Rachel Rye Butler of Greenpeace. "A permit approval allowing Canadian oil company TransCanada to build Keystone XL is a thumbs-up to likely spills in the f
