To support our environmental protection goals and to further our culture of environmental awareness, the Trans Mountain Expansion Project (TMEP) has established 10 Environmental Protection Rules (EPRs) for all Trans Mountain employees and contractors to follow at every TMEP worksite. The TMEP Environmental Protection Rules Program was developed using concepts from industry Life Saving Rules programs. Each rule is founded on data and focuses on preventing significant environmental events. The program and rules are the first of its kind to address and promote environmental protection in the industry. They are:

Watercourses and Wetlands – Minimize work in riparian habitat. Ensure all drainage, erosion and sediment control measures and spill prevention and response materials are in place.

Biosecurity – Clean equipment at required cleaning locations and maintain standardized equipment cleaning records.

Fish and Water Use – Avoid restricted activity periods for fish and complete fish salvage, water flow and water quality monitoring when required.

Heritage Resources – Avoid known heritage resources. Stop localized work immediately if a chance-find (e.g., archaeology artifact) is observed and implement contingency plan.

Spills – Maintain equipment in good working order. Use secondary containment and ensure spill kits are available and stocked.

Air and Noise – Do not leave equipment idling when not in use. Install and maintain proper sound control and dust suppression measures.

Land and Soil – Install and maintain effective drainage, erosion and sediment control measures. Ensure soil is salvaged, stored and marked appropriately.

Trespass – Ensure all construction activities and materials are conducted and retained within the approved Project footprint.

Traditional Land Use – Complete pre-construction walk-throughs for new work areas and report all site observations. Implement approved mitigation measures for all Traditional Land Use sites.

Migratory Birds – Avoid work during migratory bird windows. If work is required, conduct nest sweeps prior to activity and do not cross any migratory bird nest buffers unless authorized.

Every individual working on the Project is trained on Environmental Protection Rules in TMEP Level 1 Environmental Training. In addition, the program is officially launched at each worksite to emphasize the significance of the commitment we have made to communities, regulators and stakeholders when it comes to protecting the environment.

Environmental stewardship and leadership are rewarded through our Environmental Protection Rules Award Program. There are two tiers of awards as part of the program – Spot Awards and Quarterly Awards. Spot Awards provide immediate on-the-ground recognition of individuals and teams who demonstrate positive environmental practices. Quarterly Awards recognize teams and individuals who have shown an outstanding effort and adherence to the rules on a larger and sustained scale.

The EPRs are about holding ourselves accountable for environmental protection. If in the unlikely case that an EPR is believed to have been broken, a thorough investigation follows. Once complete, any warranted discipline takes place. Trans Mountain is committed to protection of the environment and will take every step necessary to ensure our commitments are met by all.
