Mount Polley water quality is evidence of remediation

Mount Polley takes water quality very seriously. Extensive monitoring is evidencing the effectiveness of the remediation and site water management programs undertaken by Mount Polley.

How is water quality monitored in Polley and Quesnel Lakes to ensure proper environmental monitoring is being carried out?

  • Mount Polley follows the BC-ENV approved Comprehensive Environmental Monitoring Plan. The results for all our monitoring sites are published in the publicly available Annual Environmental and Reclamation Reports.
  • You can find a link to the current report here: 2019 Environmental Report 
  • Polley Lake water met all BC Water Quality Guidelines for aquatic life parameters in 2019 with the exception of phosphorus, which was elevated even prior to mining. As Polley Lake is immediately adjacent to the mine site, this indicates the mine is doing a very good job of capturing and controlling run-off.
  • A number of sites are monitored in Quesnel Lake, and in 2019 there were no exceedances of acute BC Water Quality Guidelines.
  • At one monitoring site in Quesnel Lake, there was one minor copper exceedance of chronic BC Water Quality Guidelines in 2019, but as copper is also naturally occurring in the native soils and sediments around Quesnel Lake, and there are a number of creeks that empty into the lake near this sample site, it is difficult to know if this exceedance was natural or related to the mine.

We often get asked if we continue to discharge into Polley Lake or Quesnel Lake?

The mine discharges mine site water, that meets strict permit limits, through diffusers at depth into Quesnel Lake. This water is the only substance the mine is discharging to Quesnel Lake. The mine does not discharge water into Polley Lake.

  • Mount Polley discharges only mine site water that meets strict Environmental Management Act (EMA) permit guidelines.
  • treated by a water treatment plant, when needed to meet permit requirements, before being released into Quesnel Lake. The water going into the treatment plant (influent) is monitored on an ongoing basis, and the treated water leaving the plant (effluent) is sampled regularly for analysis. Not all water at Mount Polley requires treatment to meet EMA permit water quality guidelines before discharge, and in the past, water that was simply stored in Springer Pit was found suitable for passive discharge.
  • The lake water quality is also routinely monitored and sampled regularly as part of the mine’s Comprehensive Environmental Monitoring Plan.

Continued monitoring data confirm that remediation efforts are effective.

  • Currently, there are no indications in the monitoring data that the water discharged from Mount Polley is having any negative effects on Quesnel Lake water quality or aquatic life.
  • If you are interested in looking at water quality data collected on surface water in the area around the Mount Polley mine, in addition to data in the mine’s annual reports, results are available through the BC Government Surface Water Monitoring Sites Interactive Map.

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.

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.

Mount Polley Remediation’s 2019 Environmental Update

Extensive remediation work in the areas affected by the 2014 breach at Mount Polley has been achieved during the past five years.

Over $70 million dollars has been spent on clean-up work, including environmental impact and risk assessment studies, and remediation and monitoring of areas impacted by the spill.

Throughout 2019, the environmental department collected 1,115 water and soil samples. 336 surface water, 234 lake samples, 104 contact water, 77 groundwater, 181 seep, and 153 soil/other samples.

The construction on Hazeltine Creek concluded at the beginning of October and will re-commence at Lower Hazeltine in the Spring of 2020. The flow of Hazeltine Creek was monitored monthly.

There are 3 on-site environmental technicians to do the water sampling, environmental monitoring, inspections including reporting, database, spreadsheet data entry, communication, and coordinating meetings/tours.

Even though environmental monitoring slows down in the winter months, the environmental staff remain busy in the office with reporting, data entry, database management, scheduling, meetings, shoveling snow and general cleaning duties.

We continue to work hard to exemplify the highest site remediation standards and look forward to updating you as our work continues.

Major remediation efforts to-date at Mount Polley

Mount Polley is proud of the major remediation efforts done to-date, including the building of a rainbow trout hatchery on-site in 2018 to raise more rainbow trout for Polley Lake

$70 million has been spent on clean-up, environmental impact and risk assessment studies, and remediation and monitoring of areas impacted by the spill.

Imperial Metals, with support of its shareholders and lenders, has paid for the clean-up and remediation work. No government funding (taxpayers’ money) has been spent on the clean-up or repair work done at the site. Some of the major milestones of the Mount Polley mine’s environmental remediation efforts to-date include:

  • 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.
  • 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.
  • 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.
  • 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.
  • Clean-up and repair of 400 metres of Quesnel Lake shoreline, including placement of new fish spawning gravels.
  • Re-establishment of wetlands in the Polley Flats area adjacent to the repaired TSF.

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

Mount Polley looks forward to sharing more progress with you soon!

First Nations partners in Mount Polley remediation efforts

The Mount Polley remediation efforts have been underway for years. These efforts have benefited tremendously from the hard work of Mount Polley staff, Mount Polley’s First Nations partners, and local contractors and consultants from nearby Williams Lake. We think that its especially important to highlight the work of First Nations partners as the complementarity of environmental stewardship and responsible resource development is one that we are working to get right. We seek to accomplish this in partnership with all who have a stake in the natural wonder of where we live and work.

Mount Polley has remediation partnerships with the T’exelcemc Nation, the Xat’sull First Nation, along with the Secwepemc Nation. First Nations partners have advised and been integral to the remediation of Hazeltine Creek and other affected areas near the Mount Polley site.

Seed gathering and revegetation

Revegetation has been an important part of remediation. For example, members of the Xat’sull First Nation collected willows cuttings for subsequent planting as stakes. As a result, this work enchanced and strengthened the shoreline of Hazeltine Creek. These efforts are part of the 600,000 native shrubs and trees that have been planted. This planting was done in riparian and uplands areas near and at the affected sites. It was important to plant native species to the area. Seeds from vegetative species local to the affected area were incubated and grown in nurseries. Subsequently, these were planted when grown. The practice of seed gathering and spreading has been done on an annual basis. Along with nursery efforts, Mount Polley’s work has been extensive. The remediation project is working to restore the natural ecosystem and native vegetative species. These species include the Red Osier Dogwood and Douglas fir are now thriving.

Restoration of the vegetative species at the creek shorelines has been important for building fish spawning habitats. Thousands of rainbow trout have spawned in Hazeltine Creek. These trout now make up part of the natural habitat in Polley lake. The fish from Quesnel lake and Polley lake are safe to eat.

Mount Polley tailing spill to Mount Polley recovery

As a result, we’ve turned the corner since the Mount Polley tailings spill in 2014. Indeed, the Mount Polley remediation efforts have allowed the site to turn the corner into recovery. In a few short years, with a significant investment of over $70 million, Mount Polley is making things right and is developing new methods and refining best practices along with First Nations partners. Mount Polley is doing this to show that while Canada’s resource development sector gets it right most of the time, when it doesn’t, it makes it right.

Mount Polley recovery and remediation adds perspective

A lot has been written about the Mount Polley spill of 2014, though not so much about the remediation efforts which have been quietly underway for years to great effect. Mount Polley recovery and remediation continues. So far, over $70 million has been invested to make things right at the site and the affected areas. Let’s put Mount Polley into perspective. Local habitats are being restored. Fish spawning habitats have helped repopulate rainbow trout populations in Quesnel lake and Hazeltine Creek. The fish are biting are Polley lake!

Additionally, the project has been one that has followed scientific best practices. The Mount Polley remediation effort has restored vegegative coverage in the affected areas and is seeing local wildlife thrive at the site. The project has been carried out in coordination of Mount Polley Remediation staff along with First Nations partners.

Above all, responsible resource development means setting things right in the rare instances they go wrong. We’re proud of the work that has been done and we’re showing the world that Canada leads in taking responsibility and in developing remediation practices. Truly, Mount Polley recovery and remediation means no less than just that.

Indeed, Canada has a rich traditional of resource development and environmental stewardship. We hope to maintain that legacy and the work accomplished at Mount Polley reflects commitment to that ideal.

We’d like to highlight an article that adds much needed perspective. Dr. Lyn Anglin has written about the remediation efforts at Mount Polley. Dr. Anglin was President and CEO of Geoscience BC. She was the Chief Science Officer and VP Environmental Affairs at Imperial Metals until she retired in 2018. Dr. Anglin was also on the Advisory Council at Resource Works.
