The Trans Mountain Pipeline has returned to normal operating pressure.

The pipeline has been operating at a reduced capacity since Sunday, December 5, 2021, when it was safely restarted following a 21-day precautionary shutdown as a result of heavy rains and flooding in British Columbia and Washington state.

The return to full pressure follows the preparation of a comprehensive engineering assessment and the acceptance of Trans Mountain’s plan for return to normal operations with the Canada Energy Regulator.

Just over one week since the Trans Mountain Pipeline was safely returned to service, gasoline and crude oil continue to flow to Trans Mountain’s customers in Kamloops, Burnaby and Washington state.

While operating the pipeline at reduced capacity has begun to ease the disruption to motor fuel supply to the region, more than 400 people remain involved in the response – both on the ground and in Trans Mountain’s incident command post. With ground access to all sites now established, crews are focused on coating repairs in preparation for backfilling exposed areas, berm fortification and planning to return to full capacity. Trans Mountain will continue with these emergency works throughout the winter period to fortify the pipeline right-of-way in preparation for spring runoff. The teams are focused on the reinstatement of sites impacted by heavy rains and flooding in the regions north of Hope and south of Merritt.

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. The pipeline was restarted on Sunday, December 5, at a reduced capacity following a 21-day shutdown.

Trans Mountain utilized its Expansion Project and operational crews and equipment to reinstate 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 BC Interior regions to assist those most in need. Our efforts included providing transportation, fuel, food and water in the days following the flooding.

The Trans Mountain Pipeline was safely restarted today.

As part of this process Trans Mountain will monitor the line on the ground, by air and through our technology systems operated by our control centre.

The restart comes following the completion of all necessary assessments, repairs, and construction of protective earthworks needed for the pipeline to be returned to service. Over the coming weeks Trans Mountain will continue with additional emergency work.

December 4, 2021, 12:00 pm PDT

Following the precautionary shutdown of the Trans Mountain Pipeline as a result of heavy rains and flooding, Trans Mountain plans to restart the pipeline tomorrow.

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. Restarting the pipeline has required a significant, sustained effort to reinstate access lost due to damaged roads, changes in river flows, and adverse weather. Crews worked around the clock to clear highways, build bridges and manage watercourses to allow for access and repairs to the pipeline.

We expect that all assessments, repairs and protective earthworks necessary for a safe restart will be completed by tomorrow and plans have been developed and shared with the Canada Energy Regulator.

Subject to CER concurrence and final repair work, the restart will take place during daylight hours tomorrow and the pipe will be closely monitored by our teams in the field and technology systems operated by our Control Centre. Emergency management teams and equipment remain staged in key areas with booms proactively deployed in the unlikely event of a release.

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.

December 1, 2021, 11:30 am PDT

With continued storms bringing heavy rain causing water accumulation, crews are continually monitoring and assessing the pipeline and so far, there are no new areas of concern caused by the weather conditions. Where work has been done to shore-up banks, we are making improvements such as berm fortification to ensure the work already done is holding.

Trans Mountain has brought in more than 44,000 cubic metres of rock and gravel at critical sites and deployed several hundred sandbags to assist with shoring-up banks in flooded areas to allow the required assessment and repair work to continue. Crews are utilizing 30 sets of pumps and hoses to manage water accumulation and have set up 15 separate light-stands with generators to allow monitoring and work to continue around the clock.

We are continually assessing conditions in the region and are deploying additional resources where necessary. More than 470 people, six helicopters and some 100 pieces of heavy equipment, including three pieces of snow maintenance equipment and three sidebooms are in the Coquihalla and Coldwater regions to support getting the pipeline restarted.

We have natural hazard assessments ongoing and are focused on supporting our field teams who are working day and night in dynamic wet weather conditions near high-energy river flows. Safety of our crews and protection of the pipeline system remain our top priorities and despite the adverse conditions we are moving forward with work necessary to safely restart the pipeline.

Provided there are no additional setbacks from the latest round of rainstorms, Trans Mountain will soon complete work that needs to be done before a restart can take place. Based on current conditions and the amount of progress we have been able to make, we are only a few days away from restarting the pipeline at a reduced capacity.

This past weekend, progress continued towards a safe restart of the pipeline. However heavy rains impacted air and ground access and caused substantial accumulation of water in some areas where work is underway. Work was interrupted at some sites on Sunday November 28, 2021 due to high water or lack of access. Assessments of the impacts of the latest storm are being undertaken today with a focus on the Coldwater and Coquihalla regions. While early reports indicate much of the work to protect the worksites held up well, crews continue to reinforce berms and are continuing to improve ground access.

Based on current conditions and the amount of progress we have been able to make in the face of continued challenges with weather and access, we are still days away from restarting the pipeline at a reduced capacity. Once restarted, delivery of oil and refined products currently in the line will continue as they progress to their delivery points at either Kamloops, Sumas, or Burnaby. After initial start-up, a sustained effort will continue to return the system to its full capacity as soon as possible.

The Trans Mountain Pipeline is a critical piece of infrastructure for British Columbia and Washington state and every effort is being made to safely restart the pipeline as promptly as possible. Trans Mountain does not own the product transported in the pipeline. We are the only pipeline in North America that carries both refined products and crude oil. Depending on the needs of Trans Mountain’s customers, the amount of product shipped to four general destinations: Kamloops Terminal, Burnaby Terminal, Westridge Marine Terminal or Washington State refineries, varies from week to week.
