September site tour with the Habitat Remediation Working Group

The remediation of Hazeltine Creek has been planned and advanced through the direct collaboration of Mount Polley mine employees, government agencies, First Nations and their technical advisors. This collective is called the Habitat Remediation Working Group (HRWG).

Recently, members of Mount Polley mine, Golder Associates Ltd, FLNRO (Ministry of Forests, Lands, Natural Resource Operations and Rural Development) and the Xatśūll First Nation attended a September 2020 HRWG tour.

On the tour the HRWG inspected the construction of habitat features in Lower Hazeltine Creek. The group also inspected the weir and fish ladder at Polley Lake, the functioning spawning habitat in Upper Hazeltine Creek and the terrestrial plant growth in Polley Flats.

The group viewed all stages of remediation, from installation of habitat features to a remediated ecosystem in Upper Hazeltine Creek that is maturing into a self-sustaining landscape used by all manners of life forms.

Discussions on the tour included:
• Local nursery plant sources;
• Local contractors support in the remediation efforts;
• Reflections on how far the remediation has advanced;
• Reopening plans for the mine;
• Plans for the continued use of the weir on Polley Lake for flood control and fish rearing in Hazeltine Creek until the plants in the terrestrial flood plain mature; and
• In stream habitat features installed are potentially superior to those that existed pre-2014.

Below are some photos from the tour (September 2020).

Major milestones of Mount Polley’s environmental remediation efforts to date

The remediation effort at Mount Polley is ongoing; however, we are very proud of the major milestones that have been completed to-date.

  1. Repair of lower Edney Creek, re-establishment of link to Quesnel Lake and installation of new fish habitat for spawners from Quesnel Lake, completed in spring 2015, with evidence of successful spawning by Interior Coho, Kokanee and Sockeye Salmon.
  2. Completion of construction of a new Hazeltine Creek channel in May 2015, to control erosion and provide base for remediation of the creek itself and the creek valley.
  3. Ongoing planting of native trees and shrubs in the riparian and upland areas along the creek, now totally more than 600,000 trees and shrubs planted.
  4. Installation of over 6 kilometres of new fish spawning and rearing habitat in upper to middle Hazeltine Creek. Evidence of successful 2018 and 2019 Rainbow trout spawning in upper Hazeltine Creek.
  5. Clean-up and repair of 400 metres of Quesnel Lake shoreline, including placement of new fish spawning gravels.
  6. Re-establishment of wetlands in the Polley Flats area adjacent to the repaired TSF.

Community Remediation

Staying connected to the community during Mount Polley’s remediation

Did you know that over the past six years, over 39 community meetings have been organized and hosted by Mount Polley management and environmental staff?

Mount Polley is committed to the environment and to ensuring the community is kept up to date on remediation efforts.

Over 24 meetings have been held in Likely, the community in closest proximity to the Mount Polley mine. Meetings have also been held in the communities of Quesnel, Horsefly, Big Lake and Williams Lake.

These meetings provide an opportunity for local residents to learn about the activities and progress of the remediation work and research programs being conducted, and the opportunity to engage and ask questions.

There is still work being done to complete the rebuilding of fish habitat in Hazeltine Creek. The rebuilding and revegetating of the lower part of the creek will be the last part of the remediation work to be done.

Guest speakers have included consultants and representatives from provincial Ministries who help educate the local community about environmental remediation.

Furthermore Mount Polley has established The Mount Polley Mine Public Liaison Committee (PLC).The PLC is comprised of representatives from the local communities of Likely, Big Lake, Horsefly and Williams Lake, local First Nations, government ministries, consultants and mine staff.

Meetings are held on a quarterly basis, with the purpose to share information about activities at the mine site with the PLC members, who are there as representatives of their communities. The agenda for each meeting includes updates on mine operations, environmental monitoring, and remediation. There is also a roundtable discussion at each meeting for all participants to pose questions and discuss any community concerns.
