Remediation Plan

The Remediation Plan addresses the long-term containment and storage of the arsenic trioxide dust, the demolition and removal of all buildings on the surface, and the remediation of all surface areas including the tailings ponds. This plan is currently undergoing an environmental assessment with Mackenzie Valley Environmental Impact Review Board.  

Getting to the Plan

The Remediation Plan was developed after years of site investigations, research and extensive consultation with the public and with the Independent Peer Review Panel. From a possible 56 different management alternatives for dealing with the arsenic trioxide dust, the list was narrowed down to the 12 most viable options.

Following this extensive community consultation period, the 12 options were further refined to one "leave-in" option, and one "take-it out" option. These two options were presented to the public by the Giant Mine Remediation Project Office at several community meetings and public information workshops. See Summary of Communications Activities.

In the end, the "leave-in" option was selected and the Frozen Block Method was incorporated into the Remediation Plan for Giant Mine, based on feedback from public workshops, and the recommendations of the Technical Advisor and the Independent Peer Review Panel.
