TransCanada, the company that owns and operates the Keystone Pipeline, says that an estimated 210,000 gallons (5,000 barrels) of oil have spilled near the small town of Amherst, S.D.
The cause of the leak is under investigation, according to the company’s website. TransCanada crews detected a drop in pressure at about 6 a.m. CT Thursday morning and shut down the pipeline, which runs from Hardesty, Alberta, to Cushing, Okla., and Wood River/Patoka, Ill.
Amherst is about 200 miles north of Sioux Falls, S.D., and about 25 miles from the state’s border with North Dakota.
The conduit is not the controversial and long-delayed Keystone XL Pipeline that TransCanada is still shepherding through the approval process.
“TransCanada cannot be trusted,” said Jane Kleeb, head of the Nebraska Democratic Party and a longtime activist opposed to Keystone XL, as quoted by the Washington Post.
“I have full confidence that the Nebraska Public Service Commission is going to side with Nebraskans, not a foreign oil company,” she added.
Brian Walsh, an environmental scientist manager at the South Dakota Department of Environment and Natural Resources, said the company was aware of the spill at about 5:30 a.m. CT. But his agency wasn’t alerted until about 10:30 a.m. CT.
“There is a time lag there and I expect that that will be some of the questions we need to answer over the coming months,” he told Jeff.
In its statement, TransCanada said, “The section of pipe along a right-of-way approximately 35 miles (56 kilometres) south of the Ludden pump station in Marshall County, South Dakota was completely isolated with 15 minutes and emergency procedures were activated.”
The spill occurred about 3 miles southeast of Amherst on private land, which Walsh described as a “flat, grassy area for grazing.” The company tweeted a picture of the site late Thursday.
The company says that it is providing state and federal regulators “with accurate and confirmed information on an ongoing basis.”
