FortisBC asks customers to turn down the thermostat in wake of pipeline explosion

The electricity and gas company FortisBC is asking British Columbians to turn down their thermostats and reduce natural gas use on other appliances following Tuesday's gas line explosion near Prince George.

Puget Sound Energy and Cascade Natural Gas, bothU.S. energy companies, are also asking customers in Washington state to help conserve natural gas and electricity because of B.C.'s pipeline rupture and the impact it has on the U.S.gassupply.

In an updated statement issued on Wednesday afternoon, FortisBCsaid there had so far been a reduction in natural gas use of about 20 per cent provincewide, but that further cuts are needed.

"We still need more customers to reduce their natural gas usage as much as possible for now, as we continue to work with Enbridge and confirm the impact on the system," it read in part.

"We recognize that in some parts of B.C. it may be impractical to turn off thermostats due to cold weather. Even turning the temperature down as much as possible and reducing hot water use and other natural gas usage will help."

The Enbridge natural gas pipeline that exploded Tuesday evening is a feeder for the provincewide gas distribution system

Althoughthe fire on thepipeline has been extinguished, twoEnbridgepipelines wereshut off: the ruptured pipeand another one that's to beassessed for damage.

Late Wednesday night, FortisBC said Enbridgewasgiven NEB approval to restart the pipeline that was not damaged by the explosion.

However, they said customers should still expect a constrained supply of natural gas.

"About 70 per cent of customers could be impacted here," saidDouglas Stout, vice-president of external relations withFortisBC.

The company serves just over a million customers across the province, from the Lower Mainland to Northern B.C.

Combined, the two pipessupply 85 per cent of all natural gas used provincewide.

'Turn your thermostats down'

"Anybody who consumes natural gas, we're asking you to cut back to as little as possible and help us work through this situation to everybody's benefit,"Stout said.

"Turn your thermostats down as low as possible, obviously that depends on the region you're in what you can do, minimize the use of hot water if you've got a gas water heater, turn off your fireplace."

The pipeline is part of theT-Southsystem, stretching over 1,000 kilometres fromChetwynd, B.C., to the U.S. border, which is why it impacts gas distribution across the province and into Washington.

FortisBChas also asked industrial customers to use alternativefuel sources. Stoutsaid that those who have the ability to do so have switched off their natural gas use for now.

Canfor, a pulp mill in Prince George,has shut down two of its sawmills due to a lack of gas.

No injuries in explosion

The line ruptured onLheidliT'ennehreserve land and witnesses who saw the explosion described it as an incandescent orange fireball that could be seen for kilometres.

No one was injuredbut roughly 100 people fled their homes, including Chief DominicFrederick.

Hewants answers but says hedoesn't expect his nation's relationship with the company to change as a result.

"We're not going tomove away because of one explosion," Frederick said.

"We've lived there for most of our lives, since the pipelines were built, and we never had any concerns with the pipeline until now."

Investigation underway

The Transportation Safety Boardis responsible for the investigation into theincident andtheNational Energy Board has sent four specialists to the scene.

The B.C. Oil and Gas Commission and theB.C. Ministry of Environment, among others, are also looking into the incident.

"A cause will be determined following an investigation of this event," said Enbridgespokesperson Michael Barnes. .

"Safety is always our top focus and top priority."

The company is working with nearby communities to maintain public safety, he said, but he cannot speculate about how long it will take to resolve the situation.

"The most significant impact right now is what we are doing in terms of precautions," saidB.C. Minister of Energy MichelleMungall.

"We don't know what caused this explosion yet but once we do know, no doubt there will be some lessons to be learned and we will be implementing those as regulators."
