                                                                                                                                    Proposed Poultry
                           Growing Sheds, Ridgewood                                                                                  L 18113/BH/12-002




                            A key goal of the proposed poultry farm proposal is to allow for the reuse of
                            the spent litter on-site. The reuse minimises waste product generated from
                            the poultry farm and integrates the activity with the existing avocado orchard.


                            Given the dynamic nature of fertiliser application (Le. variations in locations
                            and sizes of application areas, varying meteorological conditions) it is not
                            considered feasible to undertake       a  reliable quantitative  modelling
                            assessment. This notwithstanding, it is considered that with the available
                            separation distance to sensitive receptors and appropriate application
                            methods there is the potential to minimise the risk of odour nuisance.


                            The proponent intends to apply litter within 4 to 5 weeks of the clean-out from
                            the sheds.                      Odour emissions from the litter will deplete reasonably quickly
                            following application (substantially reduced over several days).          This
                            operational program    will ensure  that odour emissions from the spreading of
                            litter do not coincide with peak odour emission periods from the next batch of
                            birds in the poultry sheds.        There should therefore not be significant
                            cumulative impacts from the litter spreading within the orchard and the broiler
                            farm.


                            The available setback distances from the subject site boundary to sensitive
                            receptors is summarised in Table 2 below for the receptor locations shown on
                            Figure 1.

                            It is recommended that litter not be spread within 50 metres of the southern,
                            eastern and northern                               property boundaries to minimise potential near-field
