A natural gas pipeline has ruptured in northeast British Columbia _ the second incident involving a Spectra Energy Corp. pipeline in less than a week.
Spectra spokeswoman Rosemary Silva said Friday that a line carrying sour gas ruptured Thursday night north of Fort St. John, British Columbia.
Silva says the leak was isolated by 3 a.m. Friday and has been secured so there's no risk to the public.
No injuries have been reported and it's not known how much gas may have leaked.
Two workers were injured June 23 after a natural gas leak and subsequent flash fire at a compressor station operated by Spectra Energy, north of Fort St. John.
The company is headquartered in Houston, Texas.
The Canadian Transportation Safety Board is investigating both incidents.
