CONTINUOUS AIR QUALITY MANAGEMENT

Each day on this website, the QPA posts fine particle (PM2.5) concentration data from its local monitoring station. The PM2.5 concentration reference standard is set out in the Clean Air Regulation (QLR Q-2, r 4.1). It takes into account monitoring site locations and the various potential sources of fine particles. 30 µg/m3 is the maximum 24-hour average concentration.

WHY ARE AIR QUALITY MONITORING STATIONS NEEDED?

As stated in its 2014–2015 Sustainability Action Plan, the Québec Port Authority (QPA) purchased air quality monitoring equipment and installed it on port property and in the community.

These purchases are part of the QPA's sustainability initiatives and will enable the organization to honor its commitment to collect data on dust particle levels in the air in the neighboring community and inform the community of these levels through its website.

Weather station data (wind speed and direction), dust concentration readings from the local monitoring station, and data from existing monitoring stations on port property will allow the QPA to conduct further analysis and complete its preventive monitoring and mitigation process.

Each day on its website, the QPA posts fine particle (PM2.5 ) concentration data from the local monitoring station. It should be noted that dust concentration readings alone are not enough to determine the exact source of dust.

HOW TO INTERPRET THE DATA

The PM2.5 concentration reference standard is set out in the Clean Air Regulation (QLR Q-2, r 4.1). It takes into account monitoring site locations and the various potential sources of fine particles. 30 µg/m3 is the maximum 24-hour average concentration.

To help users understand the data, the QPA posts PM2.5 concentration data in the form of graphics and numbers. If the 24-hour average concentration exceeds 30 µg/m3, the graphic will be red. The QPA has also set an alert threshold of 85% of the maximum concentration, i.e., 25.5 µg/m3. If the concentration is greater than or equal to this threshold, the graphic will be yellow. It will be green when the concentration is under 25.5 µg/m3.

QPA ACTION PLAN FOR HIGH CONCENTRATIONS AT MONITORING STATIONS

Should high PM2.5 particle concentrations be detected and meteorological data suggest that some of these particles could be coming from facilities on Port of Québec property, the QPA will immediately carry out any additional checks or analyses needed. If necessary, the QPA will post on the website the particle concentration data in its possession and the steps taken to address it with the tenant(s) in question.

METHODOLOGICAL LIMITATIONS

The particle concentrations posted on the QPA website are in PM2.5. Readings are taken at a single location in the community and may be affected significantly by a number of factors, including traffic, heating, industrial activity, and even natural sources.
