• South Bow’s Keystone pipeline is back in operation, and 3,110 barrels of crude oil have been recovered from the spill site.

• Yesterday, South Bow executives traveled to DOT HQ to meet with Secretary Duffy and PHMSA’s Acting Administrator Kochman and discuss repair and recovery efforts. South Bow is cooperating with PHMSA’s ongoing investigation into the cause of the spill, and we will continue to monitor their compliance with the Corrective Action Order issued last week.

• South Bow restarted the Keystone pipeline at a reduced pressure today. PHMSA approved the operator’s restart plan pursuant to the Corrective Action Order issued on Friday. The failed section of pipe was excavated and replaced and will be transported to a metallurgical lab in Houston for testing. The repaired line will be tested at various pressures to confirm its integrity. PHMSA investigators remain on site, and our investigation is ongoing. PHMSA will continue to monitor the operator’s compliance with the CAO.

• PHMSA issues Corrective Action Order to South Bow for Keystone Pipeline spill.

• As of 1:00 a.m. local time, five vacuum trucks recovered and removed 1,170 barrels of crude oil. Cleanup operations are ongoing. PHMSA will continue to provide updated information as we receive it.

• PHMSA dispatched a total of 8 inspectors to investigate the pipeline rupture. Six inspectors are on site in North Dakota, and 2 inspectors are stationed at the operator’s control room in Calgary to conduct interviews. 

• An estimated 3,500 barrels of product has been released. The operator of the pipeline is responsible for clearing up the spill. Thus far, 910 barrels have been cleared. 

• PHMSA investigators accessed the site of the failure and are working to determine the cause of the rupture. The investigation is ongoing and will determine what corrective action and enforcement measures are necessary. The operator will clear a path to bring in heavy equipment and excavate the site of the failure. The segment of pipe will then be removed and sent to a lab for metallurgical analysis to help PHMSA determine the cause of the failure. 

• PHMSA received a letter from the operator voluntarily committing to full cooperation with the agency's investigation and pledging a series of corrective measures. Those measures include a commitment not to restart the pipeline without prior approval from PHMSA.
