– About 5,000 barrels of oil—that's 210,000 gallons—spilled from the Keystone pipeline in South Dakota Thursday. The company that operates the pipeline, TransCanada, says in a statement obtained by KSFY that the spill "was completely isolated within 15 minutes and emergency response procedures were activated." The pipeline was shut down and "crews, including TransCanada specialists from emergency management, engineering, environmental management and safety as well as contracted, nationally recognized experts are assessing the situation," the statement continues. An environmental scientist manager at the South Dakota Department of Environment and Natural Resources tells the Bismarck Tribune officials don't think any surface water bodies or drinking water systems are threatened.
