Effects on Air Quality, EIS Additional Information Response, Section 12 (BHP Billiton, December 1995)
This response to a BHP Review Panel request presents worst-case air quality dispersion modelling results for nitrogen dioxide, sulphur dioxide, and total suspended particulates at the Ekati Diamond Mine for years 2000 and 2006, demonstrating that predicted concentrations remain below or at Canadian Ambient Air Quality Objectives. The document details revised emission factors, meteorological data, mixing heights, and proposes monitoring programs including lichen biomonitoring to verify model predictions and detect impacts on local flora.
