Keystone shutdown following oil leak

The estimated volume of the leak is approximately 5000 bbls. The section of pipe along a right-of-way approximately 35 miles (56 km) south of the Ludden pump station in Marshall County, South Dakota was completely isolated within 15 minutes and emergency response procedures were activated.

Crews, including TransCanada specialists from emergency management, engineering, environmental management and safety as well as contracted, nationally recognised 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.

TransCanada appreciates the collaborative support of local officials, emergency response personnel and commissioners in Marshall County, as well as the landowner who has given permission to access land for assessment, identification and clean-up activities.

The company has been keeping its shippers and customers up to date and has communicated that the pipeline from Hardisty (Alberta) to Cushing (Oklahoma) and to Wood River/Patoka (Illinois) is expected to remain shutdown as it responds to this incident. This does not affect the Marketlink pipeline system, which uses the facilities of the southern leg of the Keystone system from Cushing to the Gulf Coast.p>

The safety of the public and environment are TransCanada’s top priorities and the company will continue to provide updates as they become available.
