Trans Mountain is restarting construction on its pipeline expansion project.

Work will resume at the Westridge Marine Terminal and Kinder Morgan’s Burnaby Terminal as well as in communities in Alberta.

“I am pleased to announce another significant milestone for the Trans Mountain Expansion Project with the commencement of construction activities and the issuance of the notice to some contractors to begin mobilizing equipment and crews in select areas in August and September 2019,” said President and CEO Ian Anderson, in a statement.

“With the first wave of regulatory approvals complete, we are confident that we have a path forward by which the Expansion Project construction can commence.”

Contractors have 30 days to mobilize equipment, hire workers and develop work plans, with Trans Mountain expecting to have close to 4,200 workers on the job in various communities by year’s end.

Trans Mountain says start dates in the remaining construction areas will be set once final regulatory approvals and permits are in place.

“We are committed to ensuring the Project incorporates all appropriate measures to protect the cultural, environmental and local Indigenous interests in the lands and waters through construction and into operation,” added Anderson.

“Clearly this Project has been subjected to numerous delays and setbacks over the past several years. With today’s announcement on the commencement of construction, I firmly believe that we are finally able to start delivering the significant national and regional benefits we have always committed to.”

Construction had begun in some areas last year before the Federal Court of Appeal ruled the federal government had not properly consulted with First Nations.

In February, the NEB recommended that Ottawa re-approve the $7.5-billion project, which the Liberal government did earlier this summer.

If all of the approvals come as expected, the expansion project will be in-service by mid-2022.
