Pump Station Demolition- 3rd Canadian Division Support Group (CDSG), Detachment British Columbia Mainland - Chilliwack

Notice of Determination

August 21, 2026

The authorities have determined that the proposed ‘Pump Station Demolition- 3rd Canadian Division Support Group (CDSG), Detachment British Columbia Mainland - Chilliwack' project is not likely to cause significant adverse environmental effects.

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

• impacts on rights of Indigenous peoples;
• Indigenous knowledge;
• community knowledge;
• comments received from the public; and
• technically and economically feasible mitigation measures

In making this determination, mitigation measures were associated with the following components which may be affected by the various activities related to the project:

• Air / Dust / Emissions:
  • Adverse effects on air quality will be mitigated by minimizing emissions, utilizing dust suppression, and ensuring that mechanical equipment is in good working order and not working past its designed capacity.
• Soils / Contamination:
  • Adverse effects on soil erosion and risk of soil contamination will be mitigated using the Department of National Defence (DND)'s Contaminated Sites Instruction as guidance for Soil Management and Imported Fill, as well as having an in-place Soil Management Plan prior to commencement of construction. Soils will be stockpiled using proper management techniques, and tested to verify quality before any relocation, ensuring that soils are disposed of at approved facilities.
• Waste Management
  • Work on site will follow a work plan that considers proper waste management and storing of these materials. Waste will be stored in protected containment and left in secure areas.
• Hazardous Materials:
  • Before commencing any work on site, there will be a professionally developed Hazardous Materials Management and Disposal Plan to act as reference, and to refer to all legal requirements. Hazardous materials encountered or brought on site to be used will be labeled, stored with proper primary and secondary containment, and transported with care by properly trained individuals in approved vehicles. Any spills will be cleaned up with reference to the Hazardous Materials and Releases directive.
• Vegetation / Invasive Species:
  • The native vegetation on site will be conserved by maintaining the smallest pragmatic project footprint and making all efforts for any construction to only last one growing season. Any laydown and equipment storage will be restricted to designated areas, and pest management will be facilitated using the approved, workplan for invasive species management and adhering. Any exposed soils will be revegetated after the project using local seed mixes to re-establish a weed-resistant, low-maintenance succession plan.
• Wildlife Protection, Species at Risk and Migratory Birds:
  • For migratory birds, species at risk, and terrestrial wildlife and habitat, a Wildlife Protection Plan will be developed and implemented under a Qualified Environmental Professional (QEP) in accordance with the Species at Risk Act (SARA). All project activities, including mitigations and seasonal activity windows, must comply with the terms and conditions of the SARA permit required for the project to be carried out. Pre-construction surveys will be completed, and ongoing monitoring will be conducted, with wildlife rescue undertaken as required. Mitigation measures will be implemented to avoid or minimize adverse effects, consistent with Environment and Climate Change Canada guidelines for migratory birds, timing restrictions during sensitive periods, and the use of exclusion fencing in active work areas. Work areas will be maintained (e.g., mowing) to discourage wildlife use during construction, and personnel will be briefed on wildlife awareness, including reducing road use during basking periods and stopping for snakes on the road.
• Cultural / Archaeological:
  • Proposed construction is not identified to overlap with any registered archaeological or historical sites, and no adverse effects are anticipated. Should the Project Team come upon any items of potential cultural and archaeological significance, the DND Chance Find Procedures will be adhered to.

The authorities are satisfied that that the carrying out of the project is not likely to cause significant adverse environmental effects.

Therefore, the authorities may carry out the project, exercise any power, perform any duty or function, or provide financial assistance to enable the project to be carried out in whole or in part.
