                 The volume of litter has been calculated                   as   follows for the purpose of
                 designing the stockpile areas:

                                    75mm depth of litter within the sheds (conservative assumption)

                                    full litter
                                              replacement of all sheds at the end                                  of each batch
                                    (conservative assumption)
                                    total floor area of 8 sheds 13,695m2

                          q         Total litter volume of 1 027m3per batch3


                 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       mini mise   odour
                 emissions during the stockpiling period. Potential systems are manufactured
                 by ’JPH Equipment’ (http://ozturners.com.aulicwp/products/compost-turnersL)
                 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.


                 The required length of stockpiles is calculated as follows:


                                    Total litter volume of 1027m3

                                    Stockpile capacity of 2.5m3 of litter per lineal metre
                                                              4
                          q         Total 410 lineal metres       of stockpile required


                 Based upon advice from Seymour Rural Equipment Pty Ltd, Callaghan & Toth
                 has designed two bunded stockpile storage areas to accommodate up to 486
                 lineal metres of the litter stockpiles. This provides a reserve stockpile length
                 of 76 metres           as a      redundancy in the event that a larger litter volume is
                 produced from the sheds than anticipated or that a smaller volume compost
                 turning machine is used as the site.

                 The two litter stockpile areas are shown on Callaghan & Toth Plan 01 Rev 0
                 Page 9 (September2013) (refer Attachment 1) and are generally described
                 as follows:
