Dispersion modelling was conducted to assess the odour impact of a proposed beef processing facility on neighboring community. Odour samples were collected from two existing facilities that are similar to the proposed facility to determine the odour emission rate. The odour concentrations of these samples was measured by using a dynamic dilution olfactometer and the odour emission was then determined from the measured odour concentrations and the proposed ventilation rate of the facility. ISCST3 was used in conducting dispersion modelling. Results from dispersion modelling were analyzed for odour concentration and occurrence frequency surrounding the proposed facility. High odour concentration occurs in the northeastern and southwestern directions due to local weather conditions. The area within 2000 m away from the facility has most potential to be affected by odour.
