The Canadian Transportation Safety Board (TSB) is investigating the causes of two separate incidents affecting Spectra Energy Corp. facilities north of Fort St. John, British Columbia (BC).

The first, a natural gas leak and flash fire, occurred June 23 at a compressor station operated by Spectra north of Fort St. John. Two workers were injured.

Then on Thursday night a sour gas pipeline ruptured and caused a fire, which was quickly extinguished, Spectra spokesperson Rosemary Silva told NGI. There were no injuries in this incident. It was not known how much gas may have leaked.

“We’ve assembled our investigation team and they’re working with the TSB. We won’t know the cause for a while until the end of the investigation,” Silva said.
