EAs transitioning to NSCA

On July 6, 2012, the new Canadian Environmental Assessment Act, 2012 came into effect, changing the requirements for low-risk environmental assessments (EAs). As a result, the EAs underway on these projects are no longer required under the former CEA Act. However, potential environmental impacts and mitigation measures for the projects will continue to be considered under the NSCA as part of the CNSC’s licence application review to ensure no unreasonable risk to the environment or human health and safety. It is important to note that these projects will also still be subject to other relevant federal and provincial laws, regulations and standards.
