Update on Canadian Dam Association’s work re: Mount Polley tailings dam failure


The Canadian Dam Association’s Working Group is continuing its work following the failure of the tailings storage facility at the Mount Polley Mine in British Columbia on Aug. 4, 2014.


The group has been charged with identifying the issues that CDA needs to consider arising from the report of the B.C. government’s Independent Review Panel; and to make recommendations for any appropriate changes to the guidance that CDA provides to the Canadian dam industry.


Composed of members of both the CDA Mining Dams and the Dam Safety committees, the Working Group’s mandate also includes discussions and coordination with other relevant organizations.


Formed in April 2015, the group has prepared a commentary and discussed it with the members of the Panel. The Panel has subsequently been dissolved.


At this time, the group is concentrating on consideration of changes to the Factor of Safety criteria, and the definition of Engineer of Record.


Members of the Working Group have also been in regular communication with the Mining Association of Canada and the Association of Professional Engineers of British Columbia, both of which are also involved in post-failure analysis and future incident prevention.


The Group has also been working with CDA’s 2015 Conference Committee on a special presentation on the Mount Polley incident at the conference.
