Project Background & the Hearing Process

Important update on regulatory oversight of the Trans Mountain Expansion project

On August 30, 2018, the Federal Court of Appeal (FCA) released a decision that quashed the Order in Council approving the Trans Mountain Expansion project, and nullified the Certificate issued by the National Energy Board (NEB) for the Project. In the absence of the Certificate, the NEB expects that Trans Mountain will safely cease all construction activity in a manner that minimizes environmental impact. The NEB will actively monitor Trans Mountain’s actions, and take any necessary steps to ensure Trans Mountain safely and securely halts construction. As a result of the FCA’s decision, all ongoing NEB processes directly related to the Trans Mountain Expansion project, including consideration of condition compliance filings, Right of Entry applications and detailed route hearing processes, will cease.

On December 16, 2013, Trans Mountain submitted an application [Folder 2392873] to the National Energy Board (NEB) for the Trans Mountain Expansion project (the Project).

The Project includes:

  • Pipeline facilities that complete a twinning of the existing 1147 km Trans Mountain pipeline system in Alberta and British Columbia, with about 981 km of new buried pipeline;
  • New and modified facilities, such as pump stations and tanks;
  • Additional tanker loading facilities at the Westridge Marine Terminal in Burnaby;
  • Reactivation of 193 km of pipeline between Edmonton and Burnaby; and
  • Increasing Trans Mountain’s shipping capacity from 300,000 bbl/d to 890,000 bbl/d

Some temporary infrastructure, such as access roads, a worker camp, stockpile sites and contractor staging areas would also be required during construction. 

The Project represents an expansion of the existing Trans Mountain pipeline system (i.e., most of the new pipeline will be adjacent to the existing pipeline or along existing corridors). The typical width of the construction Right of Way would be 45 m, including 12 m of permanent easement.
