The pipeline is located near the Nig Creek compressor station, in a remote area approximately 130 kilometres northwest of Fort St. John.
Peter Murchland, a spokesman for Spectra Energy, said that at around 11 p.m. PT a small section of a pipeline gathering line failed.
"The line was isolated and the site was quickly and safely secured by our employees," he said via email.
Murchland said the cause of the failure is not known, but no employees were injured and the incident posed no risk to the public.
This is the second Spectra Energy pipeline incident in northern B.C. this week to be investigated by the Transportation Safety Board.
Two workers were injured Saturday after a natural gas leak resulted in a flash fire at another pipeline compressor station, approximately 160 kilometres northwest of Fort St. John.
One of the injured workers was released from care in Fort St. John, while the other was transferred to Vancouver General Hospital.
A TSB investigator has been dispatched to both sites, the agency said.Suggest a correction
