3.4 ODOUR MODELLING RESULTS

Plots of the model-predicted 99.5th percentile 1 hour average odour concentrations
over the model domain are included in Attachment 8.

The model-predicted 99.5th percentile 1 hour average odour concentrations at the
representative surrounding residences (R1 to R28, refer Figure 3) are summarised in
Table 7 below.

The results of the modelling indicate that the proposed eight shed poultry farm can
operate in compliance with the relevant 2.5 Odour Units 1 hour average 99.5th
percentile odour amenity criterion subject to the implementation of best-practice farm
management practices.
