"The duration of the price impact will depend on the length of time that the pipeline is out of service, but it may be at least one to two weeks", McTeague said.
"A cause will be determined following an investigation of the incident", Barnes said.
An evacuation order had been downgraded Wednesday to the handful of homes near the explosion site.
British Columbia's Ministry of Environment said it had been notified of the incident Shelley, B.C., and involved an 900 PSI pipeline.
"We thought it might have been a train crash or a low-flying jet", he said.
The explosion shut down the Enbridge natural gas pipeline about 15 kilometres northeast of Prince George.
A section of the pipeline owned by Texas-based Enbridge Inc. ruptured on Tuesday evening in the Lheidli T'enneh Nation community near Prince George, sending up massive flames that forced the evacuation of about 100 people and led to the shutdown of both oil and gas supply lines in the region.
"I know the priority is to keep the residents in B.C. being able to use natural gas - it's the industrial users that take the hit when this kind of thing happens and that's completely understandable", said Sampson.
As many as 700,000 customers in northern B.C., the Lower Mainland and Vancouver Island could be directly affected by a shortage, he said.
"This is a unique situation", the Premier said at an unrelated media event in Vancouver on Wednesday. He also said people north of the Lheidli T'enneh reserve have been evacuated.
Motorists beware: gas prices are set to rise across the Pacific Northwest following yesterday's pipeline explosion in Prince George.
The rupture occurred on a 36-inch transmission pipeline carrying sweet natural gas that ignited.
A statement from Enbridge issued on Wednesday afternoon said the fire had been extinguished and the company were working with the First Nations tribe to ensure there was no further disruption to their lives. "The most significant impact right now is what we are doing in terms of precautions", said B.C. Minister of Energy Michelle Mungall.
"Enbridge said it was safe to go home".
Fortis now has reserves in the pipeline south of Prince George, in its liquefied natural gas storage tanks in the Lower Mainland and on Vancouver Island, and there is some gas flowing from Alberta through a pipeline in southern B.C., he said.
Meanwhile, Fortis BC told NEWS 1130 that none of its pipelines had been damaged in the fire but that they will continue to monitor the situation.
