A section of the massive pipeline, which can carry more than 600,000 barrels a day, had its worst ever leak on December 7. The canal has been out of action for more than three weeks, disrupting crude oil markets and limiting supplies to the storage hub at Cushing. Oklahoma, the reference point for US oil prices. More than 13,000 barrels were spilled, with some of the oil entering a local creek.
Keystone has spilled more oil than any other pipeline in the United States since 2010, spilling more than 25,000 barrels, according to Pipeline Safety and Hazardous Materials Administration data. The first phase of the canal was commissioned in 2010.
