Environmental cleanup at Port Granby Project site enters first full construction season

PGP First Truckload Moving Waste_Front PageThe excavation and transportation of historic low-level radioactive waste away from the Lake Ontario shoreline to the newly built Port Granby Project engineered aboveground mound is entering its first full construction season. Waste excavation at the Port Granby Waste Management Facility site in Southeast Clarington began last November, marking a project milestone for the community. The project, as part of the Port Hope Area Initiative (PHAI), is fulfilling the federal government’s commitment to the cleanup and safe, long-term storage of approximately 450,000 cubic metres of waste, the result of the use of the site, between 1955 and 1988, by Eldorado Nuclear, a former federal Crown corporation.

Trucks are now transporting the waste along the internal route to the new Port Granby Project Long-Term Waste Management Facility, located about 700 metres north of the lake.

In March, the contractor resumed waste excavation, following a period of work slowdown during the winter and a PHAI and contractor joint review and implementation of the lessons learned during the first months of excavation. The cleanup is scheduled to take place over three years, after which the mound’s cover system will be constructed, expected to be in 2021. All contractors working on behalf of the PHAI must adhere to stringent health and safety plans, required by the Canadian Nuclear Safety Commission licence for the project, as well as industry best practices. Specific waste handling requirements are identified and measures are in place to carefully monitor the waste trucks, all of which are covered even though they do not travel on public roadways.
