According to WSP's conclusions, the modelling results demonstrate that predicted contaminant concentrations remain in compliance with applicable Quebec ambient air quality standards and criteria under the assessed operating conditions. WSP further concluded that all evaluated contaminants met applicable regulatory thresholds. The Study also noted that prevailing winds are predominantly directed toward the south-southeast, away from nearby public infrastructure, residences, and seasonal fishing cabins.
