'Is this gonna blow up?' Fear, questions from B.C. First Nation after pipeline explosion

Members of the Lheidli T'enneh First Nation near Prince George in centralB.C. say they're worriedafter homes were rocked by a pipeline explosion Tuesday, despite assurances from Enbridge the company that owns the pipeline that safety is its top priority.

Phyllis Seymour said her entire house shook whenthenatural gas line exploded at about 5:45 pm PST.She thought it was thunder until she looked out the window to see flames shooting into the air.

"To see that big fireball, it was so scary," she said. "You wouldn't even believe it was happening."

Roughly 100residents of the reserve land north of the Fraser Riverfled to Prince George, 13 kilometres away, following the explosion. Though they were given the all-clear to go home within hours, many chose to spend the night in hotels, unwilling to take any risks.

Returning home Wednesday, Seymour said she still felt uneasy.

"Like, is this gonna blow up?" she asked, gesturing to pipeline apparatus alongside the road leading to her home. "I'll be scared to go to bed tonight."

So far, little is known about what caused the incident except that there was a rupture on a 36-inch natural gas transmission line owned by Enbridge. The line is part of a system that transports natural gas from northeastern B.C. south to the Lower Mainland and some customers in the United States.

Police have ruled out a criminal cause, leaving the investigation in the hands of the Transportation Safety Board, the National Energy Board and Enbridge to determine what went wrong.

The initial fieldwork is expected to be complete within days, while the full investigation will extend over several weeks, leaving people who live near the site of the explosion with unanswered questions about what happened, and the integrity of the pipelines that pass near their homes.

We need to understand what happened here and how we can make sure it doesn't happen again.- Michele Harradence, Enbridge

"I am concerned, I've always been concerned," said Violet Bazoki, who wasn't home when the explosion happened, but could see the smoke from over 30 kilometres away.

Bazokirecalled a meeting of band members earlier in the year in which another resident asked if there was any risk of the pipeline exploding.

"[Now] something did happen," she said.

National Energy Board chief engineer Iain Colquhoun explainedhis organization's role is to make sure Enbridgeis handling the situation properly, as well as ensuringno other pipelines in the area are at risk. The boardhas already determined that a nearby 30-inch pipeline whichwas shut down Tuesday as a precaution is safe. It hasallowedgas toflowthrough it once again.

Speaking from Calgary, Colquhounsaid the last recorded pipeline rupture and explosion in Canada was in 2013.

"It's quite an unusual event," he said.

Likewise, Lheidli T'ennehChief Dominic Frederick said he wasn't particularly worried Tuesday's explosion would be repeated.

"[The pipelines] have been there for over sixty years," he said. "We've never had any concerns until now."

Michele Harradence, a senior vice presidentwith Enbridge, said she held herself personally accountablefor the safety of the pipeline and those around it.

"It's very understandable that folks are concerned, I don't blame them," she said. "It's extremely distressing to see something like this."

Harradence said the company regularly inspects its pipelinesand was concerned the ruptureoccurred despite those safety measures.

"We need to understand what happened here and how we can make sure it doesn't happen again," she said.
