The air quality assessment comprised of a baseline and impact assessment study. The baseline study included the review of the site-specific atmospheric dispersion potential, relevant air quality guidelines/limits and existing ambient air quality in the region. The predicted air quality impact assessment comprised the establishment of an emissions inventory for the current, proposed construction and future operational phases. Subsequent dispersion simulations whereby ambient air pollutant concentrations and dust fallout rates were predicted followed by a comparison to health risk and compliance requirements. An air quality management plan including possible mitigation and management measures for significant sources was developed.
