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:

  1. prepare your application
  2. provide notice to the minister
  3. 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:

  1. 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
    • the reason(s) why you believe that no reasonable person – having regard to the relevant law and to any government policies developed to guide decisions of that kind – could have made the decision
    • the grounds (facts) you’ll be using to appeal

  2. 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:

  1. 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?
  2. 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:

Proposal details

This proposal is to amend Environmental Compliance Approval (ECA) - Industrial Sewage Work (ISW) number 5775-CVTHWE issued on September 29, 2023, for the Island Gold Mine (the site), owned and operated by Alamos Gold Inc. (Alamos).

The existing approval covers the sewage works for the collection, treatment and disposal of mill tailings, process water, and mine water from the Lochalsh underground workings from the Island Gold Mine operations and processing facilities to be operated at a production rate not to exceed 461,760 tonnes per year of gold bearing ore, discharging up to approximately 27,214 cubic metres per day to Goudreau Creek discharging to Goudreau Lake. The existing approval also covers existing treatment of sanitary sewage and subsurface disposal of treated effluent, rated at a total maximum daily flow of 34,000 litres per day. The existing works consists of one tailings and primary pond, one secondary pond, and two sewage works comprising of septic tanks, partially raised leaching beds and sand mantles.

Alamos is submitting this application to include the installation of a new sewage system and updated monitoring plan. The sewage system is planned to be located approximately 500 metres southeast of the new Shaft area, with the purpose of treating domestic water from washrooms and shower facilities to be used by workers on that part of the site. The sewage system comprises a septic system with a natural attenuation. The location of the sewage system was identified as shallow bedrock with low risk of impact to current and future use of groundwater as a drinking water source. Alamos is also proposing an updated Monitoring Program to include additional new surface and groundwater monitoring locations at existing site components, as well as the proposed sewage system.
