Keystone Pipeline Release - Britton, S.D.

November 28, 2017
PHMSA has issued a Corrective Action Order (CAO) to TransCanada that requires the operator to conduct additional testing to identify and address any threats to the integrity of the pipeline system following the Nov. 16, 2017 release of crude oil from the Keystone pipeline near Amherst, S.D. The CAO states that TransCanada must operate the line at a 20 percent pressure reduction once the damaged section has been replaced and the line is restarted. PHMSA technical experts will remain deployed at the site of the spill until the line has been restarted. PHMSA personnel monitored the excavation and packaging of the damaged pipe section which was transported to NTSB labs for metallurgical testing. The investigation is ongoing.
