Attachment 5 - Traffic Impact Assessment Final PTT · 132005.638.06

To provide secondary sorting, a walking floor structure has been incorporated in the design to transfer waste
from the landfill stream to a secondary location accessible only by operators for sorting, prior to loading of
containers destined for landfill. A walking floor arrangement has been selected to optimise transfer bay
space, reduce cost in constructing a grade-separated, concrete covered area required for a loader push pit,
and to optimise the hours of safe use and waste disposal. Where waste is deposited directly into the loader
push pit, at grade or separated, there is safety risk of interaction between the loader and waste disposer, and
also for the loader from waste falling into operational areas. To mitigate this risk a large area would be
required with breaks in waste deposit to allow for loader push. It is intended that the existing site levels be
incorporated to design through a lower-level deposit location for waste at the end of the walking floor to
reduce capital cost. Safety barriers and operator supervision will be required to prevent public entering the
walking floor during operations, and breaks in waste deposit will not be required, as loader push of
accumulated waste at the base of the walking floor can be undertaken simultaneously by stopping the
walking floor periodically during loading.
The secondary sorting location includes 15m3 containers for collection of recyclable and diversion streams,
and leverages existing grade separated structures for collection for landfill. It is proposed that these
structures be modified to remove the existing safety bar preventing a fall to 30m3 containers and add steel-
faced push walls to improve ease of loader pushing waste into containers. Internally within the operator
sorting area, 15m3 containers are spaced for limited travel distance and improved speed of sorting by
operators in either bobcat with grab attachment or small loader. Access is provided in the eastern end of this
shed for loader push, and in the western end for vehicle carrying container access. The placement of 15m3
containers supports ease of load and removal, as well as replacement of containers. Visibility is reduced
during loader sorting due to bulky items and required turning movements, as such this area is not accessible
by public or commercial users of the waste transfer station and is restricted to operators with limited access
(separated by 15m3 containers within the transfer shed).
The larger section of the transfer station shed is the covered bulk tipping floor, which is sized to suit the
larger vehicles accessing site for waste transfer. This area includes an area for parking of the bobcat or
small loader (operational vehicle) and shared access to 15m3 containers and structures with grade separated
30m3 landfill containers. It is proposed that an additional structure be constructed to process the additional
quantities of waste to landfill from the combined facility and to improve access and fill volumes available to
operators. Mechanical sorting with a bobcat or small loader is likely to result in damage to more delicate
streams to be diverted from landfill, including items for Reviva and e-waste. To prevent this waste from
entering the landfill stream due to damage, crates for recoverable items are included at transfer bays.
