Development of dispersion-based setback distance guidelines for Manitoba

Project: MLMMI 2009-11


  1. To develop odour impact criteria for defining the acceptable odour exposure,
  2. To develop models for odour emission rates for various types of livestock operations in the prairie provinces,
  3. To evaluate and select a dispersion model(s) for predicting the odour distribution surrounding livestock operations, and
  4. To combine the results from the above three objectives to form a dispersion-based setback guideline.

Keywords: Odour, annoyance level, exposure, frequency, dispersion, emission

The goal of this study was to develop a dispersion-based odour impact assessment tool (OIAT) for determining setback distances.
The OIAT was developed by integrating three key elements: i) defining odour acceptability at community level; ii) estimating odour emission; and iii) predicting odour exposure by dispersion modeling.
