New ENV Permit

A new ENV permit 11678 was issued on December 31, 2020 that incorporates conditions from a previous consent order because of ongoing appeals of conditions within the permit as issued on February 1, 2020.

Quarter 4 routine monitoring activities completed:

  • Weekly WTP water quality sampling including monthly/quarterly toxicity sampling
  • Monthly water quality sampling at Hazeltine Creek 
  • Monthly & Quarterly water quality sampling of surface & mine affected waters including groundwater, mine seepage
  • Hydrological monitoring
  • Polley Lake, Bootjack Lake, & Quesnel Lake water quality sampling 
  • All critical ditches, sumps, ponds, and pipeline inspections 
  • Monthly/quarterly Waste Inspections
  • Continued investigation of unauthorized discharges and exceedances
  • Reporting—monthly, quarterly, investigations
  • Monitoring planning as per the Comprehensive Environmental Management Plan (CEMP) and ENV Permit 11678

Specialized Environmentally Related Work

During the course of the year, we enlist the help of numerous environmental consulting companies to complete some of the specialized components of the environmental monitoring done at Mount Polley Mine.  Examples include bird song surveys or benthic and invertebrate studies in the remediated areas of Hazeltine Creek.  Most of our consultants completing specialized environmental work have wrapped up their field seasons and are processing data and interpreting their field observations in preparation for delivering their reports.  Some of these reports satisfy CEMP requirements and some are stand alone studies.  The results of this work can be found in the upcoming Mount Polley Mine Annual Environmental Report.  Some of the companies that we engage with include Golder Associates Ltd, Minnow Environmental Inc., DWB Consulting Services Ltd., Ensero Solutions, and Watersmith.

Environmental monitoring is conducted in accordance with the Environmental Management Act (EMA) Permit 11678 and the approved Comprehensive Environmental Monitoring Plan (CEMP) requirements.

MPMC Water Treatment Plant (WTP) Update

In Quarter 4, the total treated water discharged to Quesnel Lake was ~1,592,581 mᵌ with an average discharge rate of ~0.2mᵌ/second.

The plant operated continuously for most of Quarter 4.  Water quality samples were collected weekly at the Water Treatment Plant (WTP) at the influent (E19) and effluent (HAD-3) sites throughout the quarter.  To further optimize the plant operations the WTP operators have been utilizing a Hanna Multiparameter Photometer to assess influent and effluent copper concentrations to help guide daily plant operations.  We are developing a data set comparing the field readings to the lab results to verify the reliability of the instrument.

Permit Exceedance

On November 11, 2020, a permit exceedance for elevated copper was observed at the WTP.  Through the course of the resulting investigation, the plant was shut down for four days, additional samples were collected (in recirculation mode), a site contact water review was completed, the source of copper was identified, plant operations and site conditions were assessed key findings were identified and operational recommendations were compiled. The plant resumed normal operation on November 27, 2020.

Bypass Request

On October 26, 2020, MPMC requested a bypass of the authorized works (the WTP) to discharge mine site contact water that is being stored in the Springer Pit without active treatment.  Through the course of the last year, the water quality in the pit has improved greatly and meets the end of pipe permit limits as indicated by the sample results taken during on-site monitoring.  This is the result of the water clarifying and passive in-situ treatment occurring in the pit.  The bypass request also included water from the Tailings Storage Facility (TSF) and the Cariboo Pit provided that they meet the end of pipe permit limits.  Significant water quality fluctuations are not expected because of the single-source nature of the bypass.  Monitoring is planned to increase in the Springer Pit to provide early warning of water quality changes and will remain at the same frequency at the end of the pipe.

Another driver for this request is to aid MPMC in eliminating surplus water currently being stored on site.  The quantity of water stored on-site currently exceeds “Best Practices” as advised by the Tailings Storage Facility Engineer of Record.  A bypass authorization will enable MPMC to increase discharge volumes while still meeting permit limits and BC Water Quality Guidelines. This will also limit year-over-year accumulation of stored water on site.  A similar bypass authorization request was submitted by MPMC in 2016 and approved by the British Columbia Ministry of Environment (MoE) on March 11, 2016.

Exploration Update

In late 2019, a comprehensive exploration program consisting of a geochemical MMI-soil sample survey and a geophysical 3D-IP survey was carried out over the Frypan/Morehead area located west and north of the Mount Polley mine. The target area is roughly 3 by 3 kilometers in size, largely till covered and shows a similar magnetic response to that obtained over the Mount Polley mine host rock of monzonite and hydrothermally altered monzonite breccia pipes. 

In June 2020, an additional 3D-IP survey was conducted over the Mount Polley mine site to identify the geophysical response of the known mineralization. 

Interpretation of the new geophysical data sets led to numerous high-priority targets both in the Frypan/Morehead area and on the mine site. 

A drill program was planned to test the new high-priority targets on and off the mine site and to expand zones of known mineralization on the mine site. The first phase of drilling was carried out at the end of 2020. 

Due to prolonged delays with assay labs, the program is waiting for results before drillings resume.

Mount Polley is Canadian Mining, Hockey is Canada’s sport

Hockey is Canada’s Sport!

And mining plays a big role in making the sport possible.

Hockey sticks, skates and nets are all made of materials mined in Canada.

The most popular hockey sticks are one-piece composite sticks — typically of graphite, though unique materials such as Kevlar and titanium are also used, and occasionally coatings such as nickel cobalt are applied for added strength.

Blades on hockey skates are generally made of tempered steel and coated with a high-quality chrome. Some blade manufacturers may add titanium to the metal.

Graphite, titanium, steel, chrome, nickel and cobalt are all mined in Canada. In fact, Nickel was first discovered in Canada in 1883, and began being mined in the 1890s.

Today, Canada is one of the world’s five top five nickel-producing countries.

Mount Polley built and managed an on-site fish hatchery in 2018

After the spill, a population monitoring program on Polley Lake indicated there had probably been a reduction in the age class of the population of Rainbow Trout (as upper Hazeltine Creek was the main spawning area for these trout). There was spawning observed in Frypan Creek at the north end of Polley Lake, however it was noted to be a much smaller habitat. The Mount Polley Environmental Team (MPET) recognized it was important to allow the fish to spawn in Hazeltine Creek, but the Habitat Remediation Working Group (HRWG) had concerns whether the spawn in the reconstructed Hazeltine Creek would be successful.

The MPET developed a backup plan. With guidance provided by Minnow Environmental and David Petkovich (Aqua-culturist), over 11,000 Rainbow Trout fry were raised in an on-site fish hatchery in spring 2018. Eggs were harvested and fertilized from some of the local Rainbow Trout that had returned to upper Hazeltine Creek to spawn.

The fertilized eggs were incubated in trays so temperature, flow and dissolved oxygen levels could be regularly monitored. Water intake was sourced from below the thermocline in Polley Lake in order to maintain cooler water temperatures.

Within two months, the eggs hatched into alevins (yolk-sac fry) and within another two weeks the yolk sacs were completely absorbed.  Throughout the incubation stage the eggs were counted, and unfertilized eggs removed.

The fry were then transferred from the incubation trays to shallow rearing tanks. When the fish reached their target biomass, they were transferred into deeper rearing tanks, and from there released into the Polley Lake watershed.

The MPET and Minnow Environmental released over 11,100 Rainbow trout fry from the hatchery into Polley Lake on September 25 and 26, 2018. The adipose fins from each fry were clipped as a means of tagging (identification). On the second day, students, parents and a teacher from Columneetza Middle School’s Greenologists / Enviro Club based in Williams Lake assisted with the Rainbow Trout fry release

Mount Polley strongly encourages Polley Lake fishers to report if they catch fish with a clipped adipose fin to gabe.holmes@mountpolley.com. This will help the MPET determine how successfully the hatchery trout are surviving. Thank you!

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.
