Draft of Proposed Updated Air Quality Model Guideline 2020

Alberta Environment and Parks is proposing to update the current 2013 Air Quality Model Guideline. The draft proposed guideline can be reviewed at: Draft Air Quality Model Guideline (PDF, 1.4 MB).

Comments on the draft proposed updated guideline should be submitted via email to:

David Lyder, Air Policy
[email protected]

The email header should contain, “Comments – draft proposed updated AQMG”. Comments must be submitted this way for consideration. Any comments submitted through other means will not be considered.

Comments must be submitted no later than midnight, October 2, 2020. Any comments submitted after this time will not be considered.

As of August 30, 2013, air quality modelling assessments commencing after this date shall follow the Air Quality Model Guideline dated October 1, 2013.

A clarification notice regarding the correct interpretation of the requirements for determining the minimum radius to be considered when determining a project’s study area as specified in the Air Quality Model Guideline was also created.

To view both of these documents, visit the Open Government Portal at:

As per Section 3.6 of the Air Quality Model Guideline, the following is the Maximum Terrain Criteria spreadsheet.

Air Dispersion Modelling

Air dispersion modelling is a method of predicting the ground level concentration of one or more sources of air pollutants.

Ground level ambient concentrations of pollutants are predicted using information such as:

  • Land use (urban/rural)
  • Meteorological data (wind speed, temperature)
  • Pollutant source information (mass emission rate/stack gas temperature/flow rate)
  • Terrain characteristics

Results from this modelling are used to determine if an air pollutant source is in compliance with ambient air quality objectives.

Non-Routine Flaring Management

Alberta Environment and Parks issued a guidance document for the modelling of non-routine flaring.

Additional information is available on the Alberta Energy Regulator website at:

Mailing List

The department has an automatic emailing system that will distribute air quality modelling related information to those who subscribe to the list. It is anticipated that this email list, along with the department website, will become the main mode by which air quality model users will be informed regarding department policy and model updates.

Subscription to this list is open to all department staff, industry, NGOs and consultants, as well as members of the general public.

All fields are required unless otherwise indicated.

The information collected through the air quality modelling – overview page will be used for distributing air quality modelling related information to those who subscribe to this mailing list.

The contact information collection is authorized under section 33(c) of the Freedom of Information and Protection of Privacy (FOIP) Act.

If you have any questions about the collection of this information, you may contact the air policy branch at 780 644-8693.
