As part of the expanded pipeline system, Sumas Terminal will receive one new tank with a capacity of 175,000 barrels. This will bring the total number of tanks to seven and a total storage capacity of  890,000 barrels. An estimated crew of 30-40 workers, during peak construction times, will install the new tank and associated infrastructure. 

Additionally, a recently proposed re-route from the approved pipeline corridor would move a valve from outside the Sumas Terminal onto the terminal property. The proposed re-route travels through Sumas Terminal, parallels the existing feeder pipelines and exits to the south through Trans Mountain-owned property back to the approved pipeline corridor. The re-route allows for all valves to be installed within the existing Sumas Terminal facility and would reduce the pipeline footprint by moving the valve to existing facility.  It would also eliminate the need to construct permanent access to the valve site from Sumas Mountain Road and reduce the potential impact of the Project to critical habitat for Oregon forest snail.

Construction Impact

Construction vehicles will access the facility from Sumas Mountain Road using North Parallel Road from Highway 1 and park inside the gates at the terminal.  Construction activities will not impact off-site public parking spaces. There will be no construction re-routes for public traffic as a result of this construction.

The construction period is March 2018 to November 2019. Hours of construction are planned for 8 a.m. to 6 p.m. during winter and 7 a.m. to 7 p.m. during summer.
