Notice of study commencement for Mountain Road Landfill leachate collection system improvements alternatives assessment

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, which last accepted waste in 2000, located at 2390 Mewburn Road, in the City of Niagara Falls.  

The purpose of the environmental assessment process is to identify any potential environmental effects associated with the proposed works and to plan appropriate mitigation measures. Notification to the public, stakeholders, and review agencies is the first step in the consultation process.

The site includes a passive and active leachate collection system to prevent discharge of leachate under 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 Waste Water Treatment Plant.  

The leachate collection system, was originally 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 leachate collection system would result in increased 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 leachate collection system. Therefore, to increase the capacity available in the sanitary sewer it was recommended that an on-site leachate treatment system be considered. Installation of a leachate treatment system, and modifications to the existing leachate collection system, requires completion of an environmental assessment process.  

This study is being planned as a Schedule ‘C’ Municipal Class Environmental Assessment study based on the Municipal Engineers Association Class Environmental Assessment 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 and on-site leachate treatment system, develop and evaluate alternative strategies, determine the most feasible solution, and minimize effects to the community and natural environment. 

Niagara Region will be hosting a Public Information Centre later this year to obtain input on the preliminary results of the study. Notification of the Public Information Centre will be advertised in the local community newspaper, and notices will be mailed to residents and businesses located within the immediate study area. Upon completion of the study, a Project File Report documenting the study process will be prepared and made available for public review and comment.
