The Trans Mountain Pipeline safely returned to service on Sunday, December 5, three weeks after a precautionary shut down as a result of heavy rains and flooding in British Columbia and Washington state.

Since re-starting Sunday, as a precaution, the pipeline has been operating at a reduced pressure. It is expected that gasoline and crude oil supply levels to Trans Mountain’s customers should return to normal levels within a week.

“The Trans Mountain Pipeline is a critical piece of infrastructure for British Columbia and Washington state,” said Ian Anderson, President and CEO of Trans Mountain Corporation. “Through a sustained and significant effort in the face of unprecedented conditions, we are proud to continue to provide safe and reliable energy transportation to the west coast, as we have for nearly 70 years.”

Throughout the shutdown period, the pipeline remained safely in a static condition and there was no indication of any product release or serious damage to the pipe. Trans Mountain completed detailed investigations of the pipe’s integrity and geotechnical assessments of the surrounding landscape to confirm readiness to restart the line.

“Our employees, contractors, officials and the Canada Energy Regulator worked tirelessly while remaining steadfast in our commitment to safety and the environment,” added Anderson. “Getting the pipe back up and into service under the circumstances is a demonstration of the many years of work we have done to maintain our pipeline system and our ongoing efforts to plan, prepare and practice for emergency situations.”

Trans Mountain utilized its Expansion Project and Operational crews and equipment to re-instate access to the pipeline lost due to damaged roads, changes in river flows, and adverse weather. Hundreds of people worked around the clock to clear highways, build bridges and manage watercourses to allow for access and repairs to the pipeline.

In addition to the restart efforts, our workforce - including our contractor teams - utilized our people and our equipment throughout the Fraser Valley, Coquihalla and B.C. Interior regions to assist those most in need. Our efforts included providing transportation, fuel, food and water in the days following the flooding.

“Trans Mountain has a strong, capable workforce with experience and expertise in responding to all kinds of emergency situations,” added Anderson. “Through our established relationships with Indigenous communities, landowners and people along our pipeline, we were able to make a difference and provide temporary housing for emergency responders and Indigenous community members at our Merritt Camp. Trans Mountain also used our expertise and equipment to carry out substantial road- clearing and bridge-building efforts to connect communities that were cut-off due to the flooding and landslides.”

Over the coming weeks Trans Mountain will continue with additional emergency work. Some of this work includes conducting additional inline inspection, armouring of riverbanks and adding ground cover or relocating sections of the pipeline.
