Mining Wastewater Permit Amendment - Sugar Zone Mine Near White River
Official title: Silver Lake Ontario Inc. - Environmental Compliance Approval (sewage)
Silver Lake Ontario wants to expand wastewater handling at its gold mine north of White River. The company needs to build a new tailings storage facility and increase how much treated water it can release into nearby Gagegenha Lake. They're also asking to adjust pollution limits based on new environmental studies.
Why This Matters
Live near White River or use Gagegenha Lake? This permit would let the mine discharge 25% more treated water into the lake daily. The company also wants to change pollution limits for some substances. If you fish, camp, or draw water from this area, you might want to weigh in.
What Could Change
If approved, the mine could release up to 2,600 cubic metres of treated water daily instead of 2,100. A new tailings facility would be built with pipelines crossing the site. Monthly pollution limits for some substances would be adjusted based on the ministry's review of environmental studies.
Key Issues
- Should the mine be allowed to increase daily water discharge to Gagegenha Lake by 25%?
- Are the proposed changes to monthly pollution limits adequate to protect the local environment?
- Is the new South Tailings Management Facility appropriately designed for safe storage?
