Odor dispersion modelling assemments for Meat Chicken farms in Australia

In Australia odor modeling is the preferred method for assessing odor impacts from meat chicken farms. New or expanding farms typically require a site specific odor impact assessment that demonstrate that the operation will have no adverse odor impacts. These are required prior to gaining approval from the regulatory agencies. This paper summarizes a standard approach used for odor impact assessments namely: odor emissions estimation, meteorological modeling and dispersion modeling. The results of the dispersion modeling has processed to enable a comparison between the different regulatory approaches used in Australia.
