Odors from intensive livestock operations have been a concern to the public. Currently, the setback distance requirement is commonly adopted in North America to mitigate odor impact. The goal of this project was to develop a dispersion-based model to determine the setback distances for swine operations. The determination of setback distances was based on the relationship between odor acceptability and odor exposure. The odor acceptability was determined through a survey of local residents. The odor exposure was quantified through dispersion modeling.
