Government tells Mount Polley to stop further tailings discharge

Imperial Metals has been told to ensure there are no more tailings discharges from Mount Polley Mine as a result of the Aug. 4 breach.

Imperial Metals has been told to ensure there are no more discharges from the tailings storage facility at Mount Polley Mine as a result of the Aug. 4 breach.

“On Sept.4, the Mount Polley mining facility was inspected by staff from the Ministry of Environment and was found to be out of compliance with the Environmental Management Act (EMA) because effluent was still discharging from the tailings storage facility into Hazeltine Creek,” the ministry said in a press release, noting an advisory was sent to the mine about the discharge concerns on Tuesday, Sept. 9.

While discharges have stopped since the Sept. 4 inspection, ministry staff are concerned future rain events will trigger further discharges.

The advisory is the first step of an escalating enforcement response to a violation of the Environmental Management Act.

More information regarding response to the Mount Polley mine incident can be viewed at the ministry’s website.
