Trans Mountain has emergency response plans and guidelines in place to ensure a timely, safe, and effective response in the event of an incident. This includes Emergency Response Plans (ERPs) for the Pipeline, Terminals & Tank Farms, and the Westridge Marine Terminal, a Geographic Response Plan (GRP) for each of Trans Mountain’s four Operational Districts, as well as an Incident Command System (ICS) Guide. While the ERPs were developed using an all-hazards approach (spills, natural hazards, etc.), Trans Mountain’s Supplemental Plans provide guidance on the assessment and management of specific hazards and/or consequences that may arise during and incident.

As a result of consultation with Indigenous groups and Stakeholders along the pipeline route, several enhancements have been made to the Supplemental Plans. For example, the Public Health Assessment and Response Plan for Airborne Health Risks was updated following discussions with health authorities in British Columbia and Alberta. In the event of an emergency, this plan may be activated in conjunction with the applicable ERP and used to determine action level criteria and subsequent steps taken to protect the public and responders. Similarly, the Non-Floating Oil Assessment and Response Plan was developed because of topics brought forward during engagement sessions and has been recently updated to include Oil Fact Sheets. Based on the results of research into product fate and behaviour, the Oil Fact Sheets include data that provides responders with information specific to products shipped by Trans Mountain, including how each product behaves in certain temperatures.

Trans Mountain’s library of Supplemental Plans also includes a Convergent Volunteer Management Plan, Decontamination Plan, Sampling and Monitoring Plan, Waste Management Plan, and Wildlife Management Plan, all of which are publicly available here.
