Rules on Local Air Quality

March 29, 2017 at 2:56 PM

On March 8, 2017 the MOECC posted key guidance documents for O.Reg 418/05: Air Pollution – Local Air Quality, including an Air Dispersion Modelling Guideline for Ontario (ADMGO), a Procedure for Preparing an Emission Summary and Dispersion Modelling Report and a Guideline for the Implantation of Air Standards in Ontario.

The Law

Ontario regulates contaminants released to air by various sources, including local industrial and commercial facilities, to limit exposure to substances that can affect human health and the environment.

If your business emits any contaminants to the air, you must comply with the regulation by meeting certain standards that may apply.

There are three compliance approaches under the regulation:

  • meet the general air standard
  • request and meet a site-specific standard
  • register and meet the requirements under a sector-based technical standard (if available)
