Proposed Project

Moosomin First Nation is proposing to conduct landfill decommissioning and reclamation of the historical dumpsite located in SW-32-47-16-W3M. Decommissioning activities will start with removing contaminated soil from mixed waste dioxins and furans from the impacted borehole site and deliver contaminated soil to appropriate facility. Following the removal of the contaminated material,  site preparation will include removing any metal, oil cans, shingles and other non-inert waste and moving any inert waste into the existing cells. Site will then be graded and contoured to ensure 3:1 slope of the material in each of the cells.  A 500 mm layer of clay will be placed and compacted over each of the two cells. A 150 mm layer of topsoil will then be placed over the clay cap followed by a native grass seed. Access to the site will be managed by placing soil mounds at the entrance of the site.
