Transboundary notification form

Introduction / Helpful Tips

Under Article V of the Canada-U.S. Air Quality Agreement (AQA), Canada is obligated to notify the U.S. of any proposed actions, activities or projects which, if carried out, would be likely to cause significant transboundary air pollution.  At present, we are providing only notification of such actions within 100 km of the Canada-U.S. border.

The form provides the information to fulfil Canada’s obligation under Article V of the Canada-U.S. Air Quality Agreement.  The form needs to be completed for any new air pollution source located within 100 km of the Canada-U.S. border that is expected to emit greater than 90 tonnes per year of any one of the common air pollutants: sulphur dioxide (SO2), nitrogen oxides (NOx), carbon monoxide, total suspended particulates (TSP) and volatile organic compounds containing at least one carbon atom, excluding carbon monoxide, carbon dioxide, methane and chlorofluorocarbons.  Notification is also required for major modifications of existing facilities which could result in an increase of 40 or more tonnes per year of one or more common pollutants.  With respect to hazardous air pollutants, notification is required if a new source, or a modification of an existing source, results in a release of greater than 1 tonne per year of any hazardous air pollutant.  For the purposes of notification, a hazardous air pollutant is any substance in the National Pollutant Release Inventory that is not categorized as a criteria air contaminant (or common air pollutant).

Please complete and submit the transboundary notification form early in the environmental assessment process, that is, at the time of registration for environmental assessment in order to provide interested parties with an opportunity to participate in the environmental assessment process.  If information on air pollutant emissions is not included in the initial notification form, please submit a new updated form that includes this information at a later date. If you are experiencing any difficulties or have any questions or comments please forward them to AQA Notification or to:

Air Emissions Priorities
Strategic Priorities Directorate
Environmental Stewardship Branch
Environment Canada
Ottawa, Ontario
K1A 0H3

If the proposed facility does not meet the Notification criteria, there is no requirement to complete and return this form to Environment Canada.
