The RCMP is hoping the latest bomb attack on EnCana's natural gas pipeline through northeastern British Columbia will finally trigger some tips.
A blast early Saturday morning caused a small sour-gas leak less than a kilometre from the site of another explosion at an EnCana gas well Thursday.
RCMP spokesman Cpl. Dan Moskaluk says the six bombings that began in October have put residents of Pouce Coupe and nearby Dawson Creek on edge.
The Mounties are labelling the bombings as domestic terrorism and have flown in a unit of its Integrated National Security Enforcement Team to investigate.
"Our crews were at the wellhead site, where they were working to stop the gas leak," EnCana spokeswoman Rhona DelFrari said from Calgary.
"Around 2:30 in the morning they heard a loud bang, so they immediately went to the spot where they thought it was and that's where they discovered the explosion at the pipeline."
Some nearby residents evacuated their homes when they heard the blast, said DelFrari, but it was unnecessary.
The small amount of leaked sour gas dissipated instantly, she said, and tests of the air showed no signs of hydrogen sulphide, which can kill in small quantities.
"So there was no risk to the public," said DelFrari.
The bombings have all taken place along a 15-to-20-kilometre stretch of the pipeline near Pouce Coupe, just south of Dawson Creek on the B.C.-Alberta border about 1,050 kilometres northeast of Vancouver.
