Canadian Nuclear Laboratories (CNL) has submitted an application to the Canadian Nuclear Safety Commission (CNSC) requesting a change to the Port Hope Area Initiative (PHAI) Cleanup Criteria.
Historic low-level radioactive waste in the Port Hope area is cleaned up to meet the levels of contaminants set out in the criteria. Through experience remediating public and private properties in Port Hope since 2018, CNL has determined that the very conservative levels of arsenic and uranium in the PHAI Cleanup Criteria are resulting in more extensive and lengthy cleanups than originally anticipated. In addition, analysis has shown that the current criteria will create significant unintended project impacts, including a noticeable loss of trees in the municipality, unless it is changed.
Community concern is strong. In the first three years of residential cleanups, the Port Hope community expressed strong frustration with the timelines and extent of the cleanups in their neighborhoods. There is also growing concern that the PHAI will result in significant undesirable changes to the urban tree canopy, the preservation of which is important to many people.
Unrestricted land use remains the goal. The proposed changes to the PHAI Cleanup Criteria would continue to leave remediated land in a condition suitable “for all current and foreseeable unrestricted uses.”
Collaboration continues. CNL will continue to work closely with the Municipality of Port Hope to ensure Council and staff are kept informed. Feedback from regulators including the Ontario Ministry of the Environment, Conservation and Parks will be incorporated as CNL follows the CNSC application and review process.
