Imperial Metals, Mount Polley Mine, BC, Canada


Description
On August 4, 2014, the retaining dam at the mine's tailings storage facility collapsed, and over 25 million cubic metres of mine tailings and contaminated water poured into Polley Lake, Hazeltine Creek and Quesnel Lake, part of the Fraser River system, one of the most important salmon rivers in the world. No-one was hurt, but Hazeltine Creek was washed out, and trees and debris washed into Quesnel Lake along with the contaminated material. The effects on water quality and fish is still unknown, and local tourism businesses as well as Indigenous subsistence fisheries have been severely affected.

Development of Alternatives1. Clean-up and remediation of the spill area. Whether the mine can return to operation has not been established.

2. Independent, public, in-depth technical reassessment of tailings facilities at existing mines, those currently being proposed, and any new proposals, based on much more stringent criteria.

3. Improved Environmental Assessment process to allow more thorough evaluation of technical aspects as well as public and Indigenous involvement.

4. Enhanced regulation and monitoring of mines.
Do you consider this as a success?Not Sure
Why? Explain briefly.The full range and extent of impacts to Quesnel Lake and downstream into the Fraser River, to the ecosystem and the economies and cultures that depend on them, are still unknown. There has been no real clean-up yet, and perhaps most importantly it remains to be seen whether deep systemic changes will be made to prevent repeat occurrences - to mining practice, regulation, and monitoring in BC and across the board.
