New Process Water Pond at Clean Harbors Hazardous Waste Facility - St. Clair Township
Official title: Clean Harbors Canada, Inc. - Environmental Compliance Approval (waste)
Clean Harbors wants to build a new pond to collect rainwater that falls on their hazardous waste facility near St. Clair, Ontario. The pond would double their current water storage capacity. It's a backup system for heavy rain events.
Why This Matters
Live near this facility on Telfer Road? This pond would be built on previously undeveloped land next to the existing landfill. If you rely on well water in the area, you may want to understand how process water from a hazardous waste site is managed.
What Could Change
If approved, Clean Harbors could build a clay-lined pond holding up to 56,000 cubic metres of process water in phase one. A second phase could expand capacity to 87,000 cubic metres. The pond would be built on land that's currently undeveloped.
Key Issues
- Should a new process water pond be approved on previously undeveloped land?
- Is the proposed clay construction adequate for containing process water from a hazardous waste facility?
