Air quality is such an important environmental health issue that for several years now, increasingly stringent regulations have been enacted around the world. These regulations have become a major issue in many engineering projects, forcing proponents to make public commitments to comply at all times with air quality standards. However, recent experiences in both the mining and industrial sectors show that it is difficult to meet those standards by considering only a conventional approach.

In this context, it is clear that an innovative approach to air quality management is necessary. Using state-of-the-art equipment and advanced risk assessment and modelling strategies, WSP has developed an innovative approach that makes it possible to modulate industrial production according to projected weather conditions, to comply with stringent environmental standards. Specifically, production can be maximized when weather conditions are favorable for dispersal of contaminants in the air, while production is decreased during unfavorable episodes, to reduce the risk of exceedance of the air quality standards in neighboring communities of industrial facilities.
