Flows resumed through TransCanada’s Keystone pipeline on Sunday after a leak detected earlier this month was repaired.
The company said in a social media post that the line resumed operations on Sunday at a reduced pressure as part of a return-to-service plan approved by the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA).
The leak was detected on April 2 at a section of the Keystone pipeline near Freeman, South Dakota and has reportedly been repaired, according to the Wall Street Journal.
The PHMSA estimated last week that the spill released about 400 barrels, or 16,800 gallons, of oil.
Calgary-based TransCanda said Friday that cleanup crews “safely cleared” over 275 feet of soil to expose the leak and perform repairs.
The cause of the spill has not been disclosed yet.
The leak temporarily halted flows through the Keystone line from Alberta, Canada to Cushing, Oklahoma.
The section of the line connecting Cushing to the pipeline’s section in Texas was operating normally during the repair work.
TransCanda said clean up and restoration work at the spill site are expected to continue over the coming days.
“Our goal for the past 65 years is zero incidents. We will apply what we learn from this incident to move us closer to that goal,” TransCanada said.
