Notice of Commencement: Environmental Assessment in Niagara Falls

Temporary relocation of the Niagara Falls Wastewater Treatment Plant Outfall and four pump station outfalls in the City of Niagara Falls

The Study

Niagara Region has initiated a Municipal Class Environmental Assessment (Class EA) to identify preferred alternatives for the temporary relocation of the Niagara Falls Wastewater Treatment Plant Outfall (WWTP) and four (4) sewage pump station (SPS) outfalls.


Niagara Region is responsible for operating and maintaining the wastewater treatment plant and most sewage pumping stations in the City of Niagara Falls.  The Niagara Falls WWTP discharges treated effluent into the Chippawa-Queenston Power Canal (Power Canal).  There are also overflow outfalls into the Power Canal located at the WWTP, Dorchester Road SPS, Drummond Road SPS, Royal Manor SPS, and South Side High Lift SPS.

Ontario Power Generation (OPG) is currently planning for temporary maintenance shutdowns of the Power Canal.  When the maintenance shutdowns occur, flow within the Power Canal will be eliminated. As a result, any discharge from the WWTP and pump stations to the Power Canal will not be possible. Instead these flows will need to be temporarily relocated, or in the case of the pump stations controlled.

Alternative solutions for the temporary relocation or control of these outfalls will be reviewed and evaluated as part of the Municipal Class EA process.  Key criteria in the evaluations will be the ability to meet the operational and compliance requirements at each facility, and provide similar protection to upstream properties as the existing outfalls.

The Process

The project is being planned as a Schedule ‘B’ undertaking, in accordance with the 2015 version of the Municipal Engineers Association Class Environmental Assessment.  The Class EA process includes public and review agency consultation, evaluation of the alternatives, assessment of the impacts of the preferred alternative and identification of measures to mitigate any adverse impacts.

A Public Information Centre is being planned for February 2018 and will present the preliminary findings of this study.  Attendees will have the opportunity to review and discuss the project directly with the Project Team.  The location and date of the Public Information Centre will be announced at a later date by means of a similar newspaper advertisement.


You are encouraged to participate in this study and provide your comments for input into the project.  Information and comments regarding this project are being collected to assist the project team in meeting the requirements of the Environmental Assessment Act.  With the exception of personal information, all comments will become part of the public record.
