Regulators order corrective action as Keystone Pipeline operators aim to restore service

BISMARCK, N.D. — Federal regulators have ordered the operator of the Keystone Pipeline to take several corrective actions after a rupture caused 147,000 gallons of oil to spill onto farmland in North Dakota, and the company said its goal is to resume deliveries to refineries on Tuesday. The Pipeline and Hazardous Materials Safety Administration directed South Bow to submit the failed section of pipe to a third-party lab for mechanical and metallurgical testing, the agency said in a statement Friday. “Multiple PHMSA investigators are on the ground in North Dakota and in the operator’s control room facility in Calgary working to determine the cause of the accident.” The order also requires an evaulation of the pipeline’s special permit, which allows the line to operate at higher-than-normal pressures, to determine if new or modified conditions are necessary. South Bow is still investigating the cause of the spill along the Keystone Pipeline near Fort Ransom, North Dakota, about 60 miles southwest of Fargo.
