Description
This study will provide an opportunity to reduce more than 72% of the GHG emissions through flaring captured landfill gas (LFG) at the closed Thornhill Landfill. This includes 75% collection efficiency of the generated methane (25% down time is assumed) and 96% thermal destruction efficiency of the captured methane. Pending feasibility of biological oxidation, the reduction can be increased up to more than 95% where the fugitive methane emissions will be biologically oxidized. As landfill gas is primarily made up of methane and carbon dioxide, flaring the gas would destroy the methane component and reduce overall GHG emissions. The Thornhill Landfill was closed in June 2017; LFG is passively collected from under the clay landfill cap and vented to the atmosphere. Oxidizing the collected or fugitive methane (thermally or biologically) will also help the Regional District of Kitimat-Stikine to achieve carbon neutral status.Municipal staff will provide logistical and administrative support to ensure that all project deliverables are met. The consultant will be responsible for the design, implementation of the gas monitoring program as well as preparing interim monitoring progress reports.
