                                                                                                                                              Noise,

                                                     Proposed Poultry Growing Sheds, Ridgewood
                                                                                                                     L26013/BH/12-002




             2.       In regard to estimating the emissions from the sheds, Pacific Environment note that the

                      K     factor used for the modelling of 2 should                have    been           2.2           to          follow the
                      recommendations in the Queensland Meat Chicken Guideline. This would increase

                      predicted impacts by 10% assuming that the impacts of potential changes with the
                      cfarifications required above do not change the model results further. Please amened
                      your modelling to incfude the appropriate K factor.


             In accordance with PEL request, the broiler emission rate model has been updated in
             accordance with the method presented in the Best Practice Guidance for the Poultry
             Industry        -
                                 Plume Dispersion Modelling and Meteorological Processing (PAE Holmes
             for DEEDI, May 2011). Specific updates were to consider a ’K Factor’ of 2.2 (i.e. with
             10% factor of safety) and a maximum ventilation rate of 10m3/hour/bird.


             The odour emission rates are lower when calculated in accordance with the PEL
             recommendations    (i.e. Best Practice Guidance document method) due to the
             conservatively high maximum ventilation rates that were previously adopted by MWA
             Environmental.



             3.       The sensitive receptors used in the report, do not take into consideration the impacts on
                      146 (which incfudes a house), 124, 172 or 224 Top Forestry Road. These lots could be
                      sold off by the applicant and a house constructed on each of them. Please either indicate
                      whether the applicant is willing to accept a condition about amalgamating the lots in to
                      the  larger lot (136 Top Forestry Road), otherwise incfude appropriate modelling
                      indicating that these separate lots ’sensitive receptors’ will not be affected by the
                      cumulative odour impacts.


             The results of the updated odour modelling (refer to Attachment 2 and response to
             issue 4. below) indicate that odour    impacts may exceed the Queensland odour
             guideline on several adjacent properties owned by the applicant.

             Advice from Gantt Legal is that a lawful condition can be imposed to address odour
             impacts at the abovementioned adjoining lands, specifically that:

                      "A condition could be imposed to the effect that the poultry farm can only operate as

                      long as the adjoining lands are owned and occupied by the operator or an employee of
                      the poultry farm. In the event that the adjoining lands are not owned and occupied by
                      the operator or an employee of the poultry farm, then a condition of approval could
                                                                                                      "
                      require odour limits not to be exceeded at those adjoining lands.
