No charges will be laid against the Mount Polley Mine Corporation, owned by Imperial Metals, for the collapse of a tailings impoundment on August 4, 2014, that sent an estimated 24 million cubic metres of mining waste into the pristine waters of Quesnel Lake.
The incident, considered one of the worst mining disasters in Canadian history, was simply the result of “poor practices,” according to B.C. chief inspector of mines, Al Hoffman, and not due to “non-compliances.”
Hoffman released the results of a yearlong investigation into the tailing pond’s failure Thursday and did not recommend charges be brought against the mine or its parent company.
The Mount Polley mine was operating within existing regulation, Hoffman found, but failed to use best available practices. Hoffman made 19 recommendations to the B.C. government and the mining industry to prevent a similar event from occurring in the future. The recommendations include introducing a “designated mine dam safety manager” to monitor tailings facilities as well as improving records management and transparency around design, construction and operation of mining facilities.
B.C.’s Ministry of Mines currently has no rule in place for levying administrative penalties against mining operators. Upon release of the report, B.C. Minister of Energy and Mines Bill Bennett said he hopes to introduce new legislation this spring that will give his ministry the power to impose fines to encourage compliance.
