Notice of Determination

Vancouver B.C. –January 22, 2026– The Vancouver Fraser Port Authority has determined that the proposed Jetty pile repairs located at 1803 Stewart Street, Vancouver is not likely to cause significant adverse environmental effects

The determination was based on a consideration of the following factors:

• Impacts on rights of Indigenous peoples
• Indigenous knowledge
• Technically and economically feasible mitigation measures

Best efforts were made to consult with the Musqueam Indian Band, S'ólh Téméxw Stewardship Alliance, Squamish Nation, and Tsleil-Waututh Nation.

Comments raised included:

• Consideration of construction methods, including the use of pre-cast concrete versus cast-in-place concrete footings.
• Clarification on barge refueling procedures and associated safety and spill prevention measures.
• Measures to prevent the release and spread of concrete material, closed-cell foam, and suspended sediments into the marine environment.
• Clarification on the disposal location and handling of removed substrate and construction debris.
• Requirements for environmental monitoring during refueling activities and in-water works.
• Implementation of marine mammal monitoring and exclusion measures during marine-based activities.
• Water quality monitoring parameters beyond turbidity, including pH monitoring during concrete and grout works.
• The need for post-construction environmental assessment.
• Measures to prevent sedimentation from on-land or marine-based machinery.
• Consideration of habitat impacts and the need for habitat restoration or offsetting.
• Spill prevention, containment, and response measures, including spill kits and contingency materials.
• Notification and response protocols for environmental incidents and spills.

The project was posted to the Canadian Impact Assessment Registry on January 15, 2025 for public comment. One comment was received, but it was not relevant to the project.

Mitigation measures and/or permit conditions taken into account in making the determination include:

• The Permit Holder shall adhere to all mitigation measures outlined in the Marine Effects Assessment (MEA).
• Refueling of equipment shall occur only in designated areas or facilities and be conducted in a manner that prevents contaminants from entering the marine environment.
• Appropriate erosion and sediment control measures, including silt curtains, netting, or geotextile materials, shall be implemented as required.
• An Environmental Monitor shall be present during in-water works to provide environmental oversight and conduct marine mammal observations prior to and during works.
• Water quality monitoring, including turbidity and pH, shall be conducted in accordance with the MEA during relevant project activities.
• All removed substrate, debris, and deleterious substances shall be contained, collected, and disposed of in accordance with applicable legislation and best management practices.
• Spill prevention, containment, and clean-up plans shall be implemented, and appropriate spill response equipment shall be available on-site at all times.
• The Permit Holder shall immediately cease work and notify the Port Authority in the event of an environmental incident or if there are reasonable grounds to believe that fish or fish habitat have been harmed.

The Vancouver Fraser Port Authority is satisfied that the carrying out of the project is not likely to cause significant adverse environmental effects.
