       The traffic expert has made some recommendations about upgrading the current access and
       improvements to the internal intersection arrangements to prioritise inbound traffic travelling
       to the existing and proposed weighbridges.

       No road safety issues are raised with the proposed development. The TIA assessment does
       not raise significant traffic impacts with the current operation of the NRRC and including the
       proposed operation of composing facility.

       6.3.2 Odour Impact Assessment

       The odour expert Katestone has considered the proposed composting facility and the current
       operation of the NRRC, including the current mulching of green waste, undertaken modelling
       and provided an Odour Impact Assessment (refer Attachment 6).

       The composting facility will be designed to process 25,000 tonnes per year of green waste
       initially, with the flexibility to accommodate growth up to 30,000 tonnes per year within the
       built infrastructure. This represents a diversion of the green waste already accepted at the
       facility, along with an 8,000-13,000 tonne increase in capacity for green waste processing 5. The
       odour considered is from green and food organic waste, during pasteurisation of the
       composting product and from leachate.

       The odour expert has advised that even with the proposed composting operation, the primary
       odour-generating activity at the NRRC will remain consistent with the existing landfill
       operation. Odour emissions from the composting operation can be expected to be very
       different in character to those of the landfill operations. Such different odours do not have a
       cumulative effect to make stronger or more offensive odours. Further, the various odours
       simply do not tend to combine or interact in such a way.

       The modelling undertaken has demonstrated that the composting facility will have a negligible
       odour impact, being highly unlikely to lead to odour impacts at sensitive receptors. The
       assessment has identified that there is a greater likelihood of the current landfill operations
       contributing to odour impacts, which is consistent with the small number of complaints
       received in relation to the landfill operations.

       The odour expert advises that the odour impacts have only been predicted in the worst-case
       upper bound emissions scenario, consistent with best practice management measures for
       controlling odours from landfill, which should be adequate to ensure that impacts are
       minimised, if not entirely prevented. The odour expert has concluded that the proposed
       composting operation, provided it is well-managed, is highly unlikely to contribute
       meaningfully to any odour impacts 6.
