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:
- A document that includes:
- your name, phone number, fax number (if any), and/or email address
- the ERO number and ministry reference number (located on this page)
- a statement about whether you are a resident in Ontario
- 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
- whether the decision could result in significant harm to the environment

- 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
You’ll need to provide notice to the Minister of the Environment, Conservation and Parks that you’re seeking leave to appeal.
In your notice, please include a brief description of the:
- decision that you wish to appeal

Original proposal
Proposal details
This proposal is for a new Environmental Compliance Approval (sewage) for modifications to existing sewage works systems servicing facilities at Riverbend Park, located at 4838 Pioneer Trail, Puslinch, Ontario.
The Park has a total of 93 existing sites and 168 sites permitted. The existing sewage systems serving the park are reaching the end of their useful lifespan and require replacement. The daily design sanitary sewage flow for Riverbend Park is approximately 74,000 litres per day. The proposed replacement of the existing sewage systems includes the installation of an advanced tertiary sewage treatment system (BNA) designed to treat the peak daily flow of up to 72,400 litres per day, with the remaining residence flows being treated by the existing conventional sewage system.
The proposed tertiary sewage treatment system will incorporate nutrient reduction for total ammonia nitrogen and phosphorus, along with UV disinfection to meet required effluent quality standards. The treated sewage effluent will be directly discharged into a culvert that leads to the Speed River. The proposed system includes multiple components, including but not limited to:
- two equalization tanks
- primary and secondary treatment tanks
- a phosphorus removal system
- tertiary filtration
The treatment process will ensure that the effluent meets all applicable regulatory requirements.
