Decision details
An Environmental Compliance Approval with Limited Operational Flexibility (air & noise) was granted to NUCOR STEEL ULC, for its bar and wire mesh products facility, located at 5400 Harvester Road in Burlington, Ontario.
The facility production limit is 294,000 tonnes of steel bar and wire mesh products per year.
The emission sources from the manufacturing and associated processes that discharge to the air include coil blasting, drawing machines, teurema line, galvanizing line, mesh line, mesh fabrication, exhaust stacks from dust collectors, general building roof vents and exhaust fans, cooling towers, boiler and emergency generators.
Emissions to the air from this facility include:
- suspended particulate matter,
- trace metals,
- nitrogen oxides, and
- noise
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 the Environmental Compliance Approval with Limited Operational Flexibility (air & noise).
The Limited Operational Flexibility conditions will expire 10 years from the date of the Approval, 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 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

- could the decision you wish to appeal result in significant harm to the environment?

In your notice, please include a brief description of the:
