The Chief Inspector of Mines for British Columbia has approved an amendment to the Mount Polley Mine Corporation Mines Act permit to allow the company to begin repairs of the breach in its tailings storage facility dam.
The amendment to the mine's permit only authorizes the company to undertake the approved breach repair work and sets out a number of conditions that must be followed by Mount Polley Mining Corporation. The amendment does not allow the mine to restart its ore processing operations.
The Mines Act permit amendment application and geotechnical design for the breach repair was reviewed by the Cariboo Mine Development Review Committee, which includes technical representatives from the Government of British Columbia, Williams Lake Indian Band, Xat'sull First Nation, Cariboo Regional District, Community of Likely, and the Department of Fisheries and Oceans Canada.
The Mines Act permit amendment can be viewed on the Mount Polley Spill Response website.
