Détails de la décision
The ECA Notice allows Clean Harbors to construct a contingency process water pond located on the north west side of the facility, adjacent to Cell 18.
- This pond is to be constructed outside of the landfill footprint, on virgin land
- The pond will be constructed in two phases. Phase 1 will have a total storage capacity of 56,000 metres cubed and Phase 2 will allow the expanded pond to have a total storage capacity of 87,000 metres cubed
- The company will initially construct the pond as Phase 1, and then construct Phase 2 if determined to be operationally required
The pond is to be used as contingency pond and be limited to emergency overflow situations during extreme weather events that exceed the capacity of the previously existing Process Water Pond system, or as additional capacity storage of Process Water during extended incinerator maintenance shutdown events.
No negative environmental impacts are expected from the construction of this pond.

Start the process to appeal
If you’re an Ontario resident, you can start the process to appeal this instrument decision.
First, you’ll need to seek leave (i.e. get permission) from the relevant appellate body to appeal the decision.
If the appellate body grants leave, the appeal itself will follow.
Seek leave to appeal
To seek leave to appeal, you need to do these three things:
- prepare your application
- provide notice to the minister
- mail your application to three parties
1. Prepare your application
You’ll need to prepare an application. You may wish to include the following things in your application:

- your interest in the decision, and any facts you want taken into account in deciding whether you have an interest in the decision
- the parts of the instrument that you’re challenging

- A copy of the instrument (approval, permit, order) that you you are seeking leave to appeal. You’ll find this in the decision notice on the Environmental Registry

What is considered
The appeal body will consider the following two questions in deciding whether to grant you leave to appeal:
- is there is good reason to believe that no reasonable person, with respect to the relevant law and to any government policies developed to guide decisions of that kind, could have made the decision?
- could the decision you wish to appeal result in significant harm to the environment?
2. Provide your notice

In your notice, please include a brief description of the:
- decision that you wish to appeal

Proposition initiale
Détails de la proposition
Clean Harbors operates an integrated hazardous waste management facility located on Lot 9 and part of Lot 8 in the Township of St. Clair. A key operational factor at the site is the appropriate management and collection of surface water at the site. One approach to managing surface water is to collect and manage water that falls onto processing areas into process water storage ponds. Currently, Clean Harbors has five existing process ponds around the site to manage process water. Due to operational needs, an additional pond is required for future weather events.
Clean Harbors is proposing to construct a contingency process water pond located on the north west side of the facility, adjacent to Cell 18. The proposed pond would be constructed outside of the landfill footprint, on virgin land.
The pond will be constructed of compacted clay. The pond walls will have a top elevation of approximately 207.3 metres above sea level and the pond base will be at 202.0 metres above sea level. The company is proposing to construct the pond in two phases. The pond constructed in phase one would have a total storage capacity of 56,000 cubic metres. The addition of the phase one pond will double the current storage capacity for process water at the facility. In phase two the pond would be expanded to have a total storage capacity of 87,000 cubic metres.
The new Process Pond will be an as-built pond as per the other process water ponds. The general layout of the pond and typical cross section of the ponds is provided in the supplemental information. The company would construct the pond as per phase one, and then construct phase two if determined to be operationally required.
