Residents are advised that we are conducting a suction dredge of the Port Hope outer harbour beginning on Friday, July 2, 2021, to remove sediment build-up of the area. During this work, the boat launch and surrounding areas will remain open until further notice. If a closure is deemed necessary, a notice will be posted on the municipal website and at the site.
The Municipality and Cameco Corporation have been working collaboratively to resolve issues related to Cameco’s cooling water intake, located along the west harbour wall, which has been impacted by sedimentation deposits. Cameco’s Conversion Facility continues to operate safely. This project also includes the installation of a silt curtain in front of the intake pipe to avoid future build up and dredging projects.
The sediment removed will be placed on the West Beach near the water treatment plant and away from the shoreline. This material will be fenced off with appropriate signage. Residents are advised to stay clear of this debris as there is loose sand and unsupervised water.
To conduct this operation, municipal staff have consulted with experts in the field of hydrology and have obtained permits/permission from the Department of Fisheries and Oceans, the Ministry of Natural Resources and Forestry, and the Ganaraska Region Conservation Authority.
In coordination with Cameco Corporation and Canadian Nuclear Laboratories, the following work will be carried out:
- Suction dredge of approximately 15,000m3 of sediment.
- Coordinate the independent testing of the sediment to ensure that it conforms to the standards of the Ministry of Environment, Conservation, and Parks (MECP) for use as beach supplement.
- If the sediment meets the MECP standards, it will be deposited at both the East and West Beaches in Port Hope.
- If the sediment does not meet MECP standards, the materials will be transported to a licensed landfill site.
Canadian Nuclear Laboratories will support the dredge operation through the Construction Monitoring Program and test for the presence of historic Low-Level Radioactive Waste (LLRW). Any contaminated materials detected will be transported to the Long-Term Waste Management Facility located in Port Hope.
