Decision details

Approval was granted for T2 to be replaced with a new power transformer (4T2). The new transformer will be equipped with a new concrete spill containment pit. The existing units will retain their existing spill containment.

The proposed spill containment system consists of building one spill containment pit for new T2, with a capacity of approximately 61.96 cubic metres, discharging to a proposed oil-water separator having an oil capacity of approximately 82.58 cubic metres.

The sump pump system being used for the current transformers T1 and T2 will be replaced by one proposed oil water-separator (OWS). The sump pump system being used for the current transformers T3 and T4 will remain.

The system at Hanover TS drains all collected runoff to two drainage outlets, which eventually flow to the south station perimeter ditch, then to a low lying area along an abandoned rail line where the majority infiltrates into the ground. A small portion of the station effluent ultimately flows overland to Lake Huron via the Saugeen River.

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
    • the outcome you’d like to see
  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
  3. Copies of all supporting documents, facts and evidence that you’ll be using to appeal
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:

  • decision that you wish to appeal
  • grounds for granting leave to appeal

3. Mail your application

  • appellate body
  • issuing authority (the ministry official who issued the instrument)
  • proponent (the company or individual to whom the instrument was issued)

This proposal is for an amendment to Environmental Compliance Approval No. 7470-4XGRM5 (industrial sewage) for Hydro One Networks Inc. for the collection, transmission, treatment and disposal of stormwater at the Hanover Transmission Station, located at 341020 Grey County Road 28, in the Town of Hanover, Ontario.

The station houses four (4) existing power transformers (T1, T2, T3 and T4). T2 will be replaced with a new power transformer (4T2) and the existing T1, T3 and T4 will remain. The new transformer will be equipped with a new concrete spill containment pit. The existing units will retain their existing spill containment.

The proposed spill containment system consists of building one (1) spill containment pit for new T2 with a capacity of approximately 61.96 cubic metres, discharging to a proposed oil-water separator having an oil capacity of approximately 82.58 cubic metres.

The sump pump system being used for the current transformers T1 and T2 shall be replaced by one (1) proposed oil water-separator (OWS). The sump pump system being used for the current transformers T3 and T4 will remain.

The system at Hanover TS drains all collected runoff to two (2) drainage outlets which eventually flow to the south station perimeter ditch then to a low lying area along an abandoned rail line where the majority infiltrates into the ground.
