A CBC News investigation has learned that TransCanada Pipelines — the Canadian company behind the controversial U.S. Keystone XL pipeline proposal — was troubled by quality-assurance problems on another recent American pipeline that exploded.
The Bison natural-gas pipeline exploded in a remote area near Gillette, Wyo., on July 20, 2011, six months after it went into service.
The explosion blew out a 12-metre section of pipeline and shook buildings more than a kilometre away, but caused no injuries or death.
