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 runoff at their hazardous waste facility near St. Clair, Ontario. The pond would be built on undeveloped land next to their existing landfill. It would double their current water storage capacity, helping manage heavy rainfall events.
Why This Matters
Live near St. Clair Township? This hazardous waste facility wants to expand onto new land. The pond would collect water that falls on areas where waste is processed. If you're concerned about groundwater or land use near the site, this is your chance to weigh in.
What Could Change
If approved, Clean Harbors could build a clay-lined pond with 56,000 cubic metres of storage capacity in phase one. A second phase could expand it to 87,000 cubic metres. The facility's footprint would grow onto previously undeveloped land.
Key Issues
- Should the facility be allowed to expand onto undeveloped land?
- Is a clay-lined pond adequate for containing process water from a hazardous waste facility?
- What are the potential impacts on local groundwater and the environment?
