Latest update – 2:28 p.m. CST, November 16, 2017
At approximately 6 a.m. CST (5 a.m. MST) on Nov. 16, we safely shut down the Keystone pipeline after we detected a pressure drop in our operating system resulting from an oil leak that is under investigation.
The estimated volume of the leak is approximately 5,000 barrels (210,000 gallons according to the AP). 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 within 15 minutes and emergency response procedures were activated.
The safety of the public and environment are our top priorities and we will continue to provide updates as they become available.
Crews, including TransCanada specialists from emergency management, engineering, environmental management and safety as well as contracted, nationally recognized experts, are assessing the situation. TransCanada is providing State and Federal regulators, including the Pipelines and Hazardous Materials Safety Administration (PHMSA) and the National Response Center (NRC), with accurate and confirmed information on an ongoing basis.
