Effluent treatment and discharge
Now that we are well into summer, the project team has begun to discharge treated effluent (which, in our case, is minewater) from the Giant Mine site. The effluent is treated for various metals, including arsenic, before being discharged into Baker Creek. This is a yearly event, and the effluent is treated and sampled as per Environment and Climate Change Canada's Metal and Diamond Mining Effluent Regulations prior to release. This helps ensure people, fish, and fish habitat are protected. More information about the project's management of water on site is available on the Treating the water at Giant Mine page.
Regulatory process update
Since April 1, 2019, the Giant Mine Remediation Project's water licence and land use permit applications have been working their way through the regulatory process. On April 10, 2019, the Mackenzie Valley deemed the project's application complete. That meant that organizations and members of the public could begin to submit review comments about the application through the board's online review system. The project was given 3 weeks to respond to more than 850 reviewer comments, which are available to the public here:
- land use permit application
- water licence post-environmental assessment information package
- management plans, group 1 (standard)
- preliminary screening information
- Closure and Reclamation Plan
- management plans, group 2 (water)
- management plans, group 3 (other)
The reviewer comments the board received were used to determine the topics for the technical sessions. The purpose of the technical sessions is to allow parties to gather information to help prepare for the coming public hearings. The first of 2 sets of technical sessions were held July 9 to 12, 2019. At the session, the project team gave presentations on many of the technical components of the site. This was followed by time for reviewers to ask a series of questions on each topic. The sessions often went into the late evening and covered a wide breadth of information. The technical team, led by Natalie Plato, Jane Amphlett and Erika Nyyssonen, was prepared with in-depth responses to questions, having worked with the project team in advance to consider all topics that might be raised.
The second set of technical sessions are currently scheduled to occur from September 9 to 13, 2019. The public hearings are expected to take place in January 2020. Information about the water licence process is available in the April 2019 enewsletter.
The Mackenzie Valley Land and Water Board is best positioned to answer questions about the Water Licence regulatory process.
The project team and its partners and stakeholders have been focused mainly on the regulatory process over the past few months. However, regular engagement bodies such as the Working Group have continued to meet and, on July 4, 2019, the annual site tour took place. This year featured a tour of both the surface and the underground.
