Client: Columbia Shuswap Regional District 
Location: Sicamous, BC



XCG completed an updated Design, Operations and Closure Plan for the Sicamous Landfill. The plan was updated to meet the current Landfill Criteria and includes a detailed landfill filling plan, surface water management infrastructure, access roads, landfill gas assessment, soil management plan, and a closure plan (including final contours and cover design and post closure plan). Landfill liability and closure and post-closure fund assessments were also completed as part of the project.

The key objectives of the Design, Operations and Closure Plan were to:

  • Provide an updated fill plan which addresses the need to reduce leachate generation, optimize surface water controls, and optimize available landfill airspace;
  • Provide a closure plan including implementing a low permeability cover system;
  • Provide a post-closure plan for the landfill; and
  • Reduce long-term environmental impacts associated with the landfill area.

The resultant Design, Operations and Closure Plan is a comprehensive and integrated design document which addressed all the aforementioned objectives. The Design, Operations and Closure Plan included a detailed development strategy for the existing landfill footprint, providing approximately 111,419 cubic metres of airspace with an option to fill to a higher elevation providing an additional 52,024 cubic metres. Based upon population growth projections and fill rate assumptions, it is estimated that the Site will reach design capacity in 2035, or 2043 if additional filling is completed.
