6.10.2. Impact Assessment
Whilst the scale of mineral waste to be generated may increase through the proposed amendment, no
additional waste impacts are anticipated as the Upper Mundic Gully TSF has been designed in
accordance with best practice in accordance with relevant DETSI Guidelines and ANCOLD and
provides additional engineering controls in the form of robust bituminous geomembrane liner to reduce
seepage. The setting within Upper Mundic Gully provides the most favourable location to mitigate
potential environmental harm associated with typical TSF hazards such as overtopping and piping
failure.
Approval and operation of the Upper Mundic Gully TSF will reduce the likelihood of overtopping events
from structures potentially impacting offsite environmental values and reducing operational pressures
on the DNRMMRRD operated Water Treatment Plant that adjoins the OCP.
Waste storage features have, and will continue to operate under the requirements of the site waste
management plan and Schedule E – Waste of the EA.
6.10.3. Management Practices
Heritage Minerals Waste Management Procedure provides standard controls for management of
construction and operational waste. This includes implementation of the waste hierarchy, identification
and segregation of waste streams, waste disposal and waste tracking. All construction and operational
waste (excluding mine waste) that cannot be economically returned to suppliers, reused or recycled
offsite will be sent to local landfill or other licenced waste disposal facility in accordance with current
