The APTR is continuously working on the implementation of its Environmental Policy, in particular through a continuous air quality management network. This network was set up in 2014 and includes four monitoring stations at the northern limits of the port area, at the interface of the port site and the nearby community. The instantaneous results of the total particulate concentration are continuously analyzed. The reference air quality standard for total particulate matter concentration is that presented in the Clean Air Regulation (R.S.Q. Q-2, r.4.1).

Approaching the limit indicates a potential problem and allows appropriate corrective and preventive measures to be put in place. Measures to reduce dust may include the use of a tank truck or mechanical sweeper, a reminder message for reducing the speed of all moving vehicles (maximum speed 30 km/h), the use of fog guns, a reduction in operations speed, a change in handling methods to reduce dust dispersion, and other specific strategies.

All these interventions are intended to effectively control dust and, as a result, help reduce the health risks, air quality problems, as well as nuisance and inconvenience associated with the presence of dust. The TRPA works continuously to establish collaborative communication channels with users to monitor actions to improve air quality.
