Détails de la décision
An Environmental Compliance Approval with Limited Operational Flexibility (air & noise) was granted to Owens Corning Insulating Systems Canada GP Inc., for its Scarborough site located at the 3450 McNicoll Avenue, Toronto, Ontario.
The facility production limit is 240 tonnes of bare molten glass per day.
The application includes all sources at the facility, including:
- dust collectors
- tanks
- cooling towers
- furnaces
- oven
- paint spray booth
- heaters and boilers
- regenerative thermal oxidizer
- wet electrostatic precipitators
Emissions into the air from this facility include:
- nitrogen oxides,
- crystalline silica,
- particulate matter
- manganese compounds
- chromium compounds
- odour
- lead
- nickel
The Environmental Compliance Approval with Limited Operational Flexibility (air & noise) requires that the company demonstrate compliance on an ongoing basis with Ontario Regulation 419/05, applicable Ministry Guidelines for Air and Noise and other performance requirements as specified in their conditions. It permits modifications such as process changes, de-bottlenecking or addition of new equipment subject to limits on operational flexibility that include a production limit for the facility to be specified on Environmental Compliance Approval with Limited Operational Flexibility (air & noise).
The Limited Operational Flexibility conditions will expire on December 31, 2028, unless this Approval is revoked prior to the expiry date. The company will be required to make application for amendment at that time to renew these conditions. Of specific public interest, one condition that is included with the Environmental Compliance Approval with Limited Operational Flexibility (air & noise) requires the company to make available, at all times, at the facility for inspection by interested members of the Public, a table (emission summary table) that documents the facility’s compliance with Ontario Regulation 419/05.

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
- 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
- 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
- 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:
- 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
- grounds for granting leave to appeal
You can provide notice by email at minister.mecp@ontario.ca or by mail at:
College Park 5th Floor, 777 Bay St.
Toronto, ON

3. Mail your application
You’ll need to mail your application that you prepared in step #1 to each of these three parties:
- appellate body
- issuing authority (the ministry official who issued the instrument)
- proponent (the company or individual to whom the instrument was issued)
