Closed Mountain Road Landfill Leachate Collection System Improvements Environmental Assessment
All Niagara Region projects

About the Project

Niagara Region has initiated a Municipal Class Environmental Assessment study to assess the leachate collection system and leachate treatment options at the closed Mountain Road Landfill. The assessment will identify potential environmental effects associated with the proposed works and appropriate mitigation measures.

The Mountain Road Landfill has been inactive since 2000 and is located at 2390 Mewburn Rd. in Niagara Falls.

The site includes a passive and active leachate collection system to prevent discharge of leachate under the Ministry of the Environment, Conservation and Parks Environmental Compliance Approval No. A120201. All collected leachate and groundwater is currently directed to the sanitary sewer, which is then treated at the Niagara Falls Wastewater Treatment Plant.

The leachate collection system was constructed in 1973, and currently functions ineffectively. Niagara Region is proposing to improve the leachate collection system at the closed Mountain Road Landfill. An improved system would increase collection of leachate. Preliminary work has identified that there is limited capacity in the sanitary sewer to accommodate an increase in the collection of leachate from an improved system. To increase capacity in the sanitary sewer, it's recommended that an on-site leachate treatment system be considered. Installation of a leachate treatment system, and changes to the existing system, requires an environmental assessment.

This study is being planned as a Schedule 'C' Municipal Class Environmental Assessment study based on the Municipal Engineers Association Class process, which is a planning process approved under Ontario's Environmental Assessment Act. The study will define the problem(s) / opportunities associated with options for improvements to the leachate collection system, develop and evaluate alternative strategies, determine the most feasible solution, and minimize effects to the community and natural environment.
