YUL Montréal-Trudeau International Airport - Addition of Above-Ground Fuel Storage Tanks at the YUL Garage

Notice of Determination

ADM Aéroports de Montréal has determined that the project to install three aboveground fuel tanks at YUL Montréal-Trudeau International Airport is not likely to cause significant adverse environmental effects.

This decision is based on the following factors:

• The tanks are installed inside the airport area, in the area of the maintenance garage, on an already developed site;
• Mitigation measures applied during the installation work;
• Community knowledge;
• Knowledge and the rights of indigenous peoples.

The factors taken into account in this determination are as follows:

Noise environment and air quality

• No impact;
• Increase of the airport site's capacity for the use of renewable diesel and thus reduce GHG emissions from mobile ground service equipment.

Soil quality

• The quantities of soil excavated will be limited; if applicable, the soils will be characterized and managed in accordance with the applicable regulations.

Surface water quality

• No impact;
• A new hydrocarbon separator is added to the site's local rainwater system.

Consequently, ADM Aéroports de Montréal may exercise its powers, duties and functions to enable the project to proceed.
