In 2016, the NSW Environment Protection Authority (NSW EPA) identified a need for a more standardised and reliable tool to predict the potential odour impacts from proposed poultry farms. A research project was conducted which identified inputs required for odour dispersion modelling from tunnel-ventilated broiler sheds, and tested the sensitivity of the modelling outcomes to variations in each of those inputs. The modelling investigations focussed on one case study site, the “Project Farm”. The Project Farm was a broiler farm near Tamworth where odour complaints had occurred despite the farm development proposal being supported by odour modelling indicating compliance with odour criteria. The project included both desk-top and field investigations, and resulted in a “Recommended Good Practice Methodology” for broiler farm modelling being developed, which grouped the various inputs by significance. The most important factors affecting dispersion results from broiler farms were: 1. Selection of dispersion model. 2. Meteorology, in particular the availability of real measurements for wind speeds <0.5 m/s, coupled with definition of minimum sigma-v in CALPUFF settings. 3. Buoyancy-enhanced dispersion. 4. Selection of percentile for post-processing of model results. 5. Representative definition of odour emission rates. This paper presents the findings of the project that demonstrate the importance of these factors in the modelling of broiler farm odour emissions. These findings should not be construed to represent current NSW EPA Policy. [ABSTRACT FROM AUTHOR] |
