Background The Clover Bar Landfill (CBLF) is located at the Edmonton Waste Management Centre (EWMC) at the SE and SW 28-53-23 W4M. The total area of the site is 198 acres (80.2 hectares). The landfill is comprised of two areas, Area 1 which was developed between 1974 – 1985, and Area 2 which was developed between 1985 – 2010. The estimated total municipal solid waste (MSW) contained between both areas is 14.2 million tonnes. Approximately 60% of the landfill has been capped since the termination of its operation in 2010 and the final cover is planned to be completed by the end of 2022. Owner has commercial rights to the LFG generated at the EWMC until 2024 and currently operates the LFG wellfield located within the Clover Bar Landfill (EPEA Approval 47140-02-00) on behalf of the City of Edmonton (the City). In addition to operation of the LFG wellfield, Owner also owns and operates an aged LFG collection and control system (LFGCCS) located just South of the Landfill which feeds a LFG-to-Electricity (LFGTE) system also owned by Owner (EPEA Approval 10448-03-00). In order to maintain regulatory compliance at the Landfill with regards to GHG emissions, the City has undertaken a project to replace the aged LFGCCS with the development of a new LFGCCS (by others). The new LFGCCS is currently under development by the City as a separate project and will be co-located at a new location. It is expected that the new LFGCCS will allow for greater collection efficiency of LFG from the Landfill. In parallel, a proposed LFG to RNG project will replace the aged LFGTE system and will be connected to the new LFGCCS. The LFG to RNG system will consist of a LFG Conversion System and an RNG Injection Station (by ATCO). The new Site will be permitted as an amendment to the existing Clover Bar Landfill Approval EPEA Approval 47140- 02-00 and encompass all infrastructure related to collection, flaring, LFG conversion, and injection of LFG and RNG into the natural gas grid via a planned ATCO injection station which will be co-located at the Site. In general, the current operating philosophy for the Site is such that the existing LFGCCS directs LFG to either be flared or combusted in reciprocating engines. Once the LFG to RNG Project is operational, the existing LFGCCS and LFGTE systems will be decommissioned and replaced by a new, fully integrated LFGCCS and LFG-to-RNG system.
