The Federal Court of Appeal decision issued on August 30, 2018 cancels the Order-in-Council which had approved a Certificate of Public Convenience and Necessity (CPCN) for the Expansion Project.

As a result of the decision, Trans Mountain is winding down in-field construction activities in a safe, secure and environmentally appropriate manner. Some activities may take some time to complete to ensure the sites are properly secured, are safe and that risk to the environment, the public and workers is minimized.

Trans Mountain intends to continue working on the activities listed below.

Westridge Marine Terminal – Burnaby, BC

Construction activities at Westridge Marine Terminal began on September 29, 2017 and included both marine and foreshore construction. The safe shut down is underway and activities yet to be completed include:

  • The installation of pile caps on upright piles with open tops in order to mitigate the potential for entrapment of wildlife.
  • Maintenance/installation of erosion control mitigation on the foreshore to protect exposed areas of the foreshore. 

In addition, there are three sheet piles cells which are in varying stages of completion. In order to safely shut down marine construction we need to drive piles to elevation and backfill each of the cells in order to maintain the safety and integrity of the sheet pile structure. If left unfinished for an extended period of time the integrity of the sheet pile structures may be compromised resulting in a safety hazard and increased disturbance in the marine environment.

Spread 2 – Yellowhead, AB

Pipeline construction began in Spread 2 on August 25, 2018, and the safe shut down of activities is expected to be complete by the end of September. The demobilization of activities is underway and the activities yet to be completed including the removal of stakes, flags and signage and cleared trees.

Temporary Infrastructure Sites

There are six temporary infrastructure sites in BC and Alberta which have been or will be developed for the purpose of storing Project materials in a safe and secure manner. We have acquired materials that are in various stages of the production process (manufacturing and shipping) and will need to receive these materials at locations in BC and Alberta to be secured for future use.

Burnaby Terminal

Trans Mountain was in the final stage of construction of a security fence to protect the safe operation of its existing Burnaby Terminal facility and has approvals for piping modifications needed within the existing terminal site. Trans Mountain intends to proceed and complete these activities.

Surveys, Studies and Operational Maintenance

Trans Mountain intends to continue design and pre-construction surveys, studies and operational maintenance activities. These activities may include environmental surveys (i.e. wildlife), geotechnical studies, integrity assessment activities with respect to existing assets, and installations (i.e. fencing) to secure and protect existing facilities.
