                  3.1.7    LITTER STOCKPILING


                  Litter is to be stored within two bunded areas as shown on Callaghan & Toth
                  Plan 01 Rev 0 Page 9 (September 2013) (refer Attachment 1) and are
                  generally described as follows:

                                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



                  The stockpile areas are to be constructed as bunded areas to minimise
                  stormwater inflows and contain runoff. The surface will be clay capped
                  to minimise infiltration.   Runoff captured within the bunded         areas   will be
                  treated via    a   wet sediment basin and bioretention basin to remove
                  sediment and nutrients prior to discharge to the orchard with overland
                  flow directed to the dams. Further detail in relation to the management of
                  potential water quality impacts from the bunded compost stockpile areas is
                  contained in the Storm water Treatment and Water Quality Management
                  Plan (Callaghan & Toth, Version 3, September 2013).


                  Litter will be transferred to the stockpile areas by truck and the initial
                  stockpiles formed by tractor, bobcat or backhoe. The stockpiles will be
                  covered using polyethylene sheet or similar to minimise fugitive dust and
                  odour emissions during the storage period.


                  It has been determined by the proponent that the use of a compost turning
                  machine (tow-behind tractor) will be the most efficient means of stockpiling
                  the spent litter and maintaining aerobic conditions to minimise odour
                  emissions during the stockpiling period.       Potential systems are
                  manufactured                 by              ’JPH                Equipment’
                  (http://ozturners.com.au/icwp/products/compost-turners/) and       Seymour
                  Rural Equipment Pty Ltd (http://www.seymourrural.com.au/compost-turner-
                  4000.html) and can integrate stockpile covers (i.e. pick and replace covers
                  after turner passes along stockpile).     The compost turning machines
                  produce linear stockpiles approximately 1.5 metres high by 3 metres wide.

                  Advice from the manufacturer is that a Seymour ’Compost Turner 4000’
                  produces linear stockpiles that will hold approximately 2.5m3 of litter per
                  lineal metre of stockpile.
