Re: Response to Sunshine Coast Regional Council Outstanding Issues Request – Proposed Poultry
      Growing Sheds, Ridgewood                                                 L18113/BH/12-002



                Northern Stockpile Area (adjacent Shed 5)
                300 lineal metres of stockpile within a 120m x 22.5m bunded area
                76 lineal metres of reserve stockpile within a 82m x 14m bunded area

                Southern Stockpile Area (adjacent Shed 3)
                110 lineal metres of stockpile within a 75m x 19m bunded area


        Specific details requested by SCRC are summarised as follows:

            Litter stockpiling time
                4 to 5 weeks (including spreading) commencing from day of cleanout.

                If, due to unforeseen circumstances, litter is not able to be spread
                within the available 4 to 5 week period then, in the event of odour
                nuisance, the litter may be removed from the site by a regulated waste
                transport company as occurs for many broiler farms that do not have
                to ability to reuse the material on-site.


            Footprint of the Spreading Area
               Litter is to be spread on the terraces containing avocado trees (not to
               steep slopes) which will act to control runoff from the fertilised areas.
               In accordance with the Queensland Department of Agriculture,
               Fisheries and Forestry Guidelines: Meat Chicken Farms (2012) a
               minimum buffer of 50 metres is to be maintained between litter
               spreading areas and waterways, including Blackfellow Creek. It is
               also recommended that a minimum setback of 50 metres is retained
               from spreading areas to the southern, eastern and northern property
               boundaries to avoid near-field odour influence on adjacent properties.

            Spreading Area Timeframes
               Litter will be spread from the stockpiles within 4 to 5 weeks of the litter
               being removed from the sheds. It is recommended that litter only be
               spread during the 6am to 6pm period and when winds are from
               easterly directions to ensure that odour emissions are directed
               towards the state forest and away from sensitive receptors.

            Litter Moisture Content
                In order to manage odour and dust emission potential from the sheds,
                litter moisture content is to be maintained in the range 15% to 30%.
                This will be the moisture content upon placement in stockpiles. For a
                commercial composting operation, litter moisture content may
                approach 50% but this is unlikely to be the case at the subject site
                given that the stockpiles are to be covered and will only be maintained
                for 4 to 5 weeks. The final moisture content in the stockpiles is likely
                to be in the order of 30 to 40% prior to spreading.
