Reasons for a Federal Assessment

On September 13, 2004, it was determined that an environmental assessment was required in relation to the project because the Canadian Nuclear Safety Commission considered taking action in relation to subsection 24(2) of the Nuclear Safety and Control Act and Natural Resources Canada considered providing financial assistance to the proponent.

Project Description (as posted in the Notice of Commencement)

The plutonium recovery laboratory, constructed in 1947 and in operation from 1949 to 1957, was designed to extract plutonium isotopes from enriched fuels used in research reactors in operation during that period. Decommissioning of this facility will be carried out in three phases and include the following activities: removal of all remaining process equipment and piping; decontamination of all structures, including the inner concrete shielding structure; segregation and transfer of wastes to waste management facilities at the CRL; and site decontamination and restoration.

Final Decision

On July 6, 2012, the new Canadian Environmental Assessment Act, 2012 came into force which replaced the former Canadian Environmental Assessment Act. As a result, there is no longer a requirement to complete the environmental assessment of this project.
