6.5.2. Impact assessment
Based on GHD (2016) noise and vibration modelling, the construction phase of the project is unlikely
to affect sensitive receptors. Standard noise and vibration management measures will be implemented
in accordance with best practice environmental management to reduce potential for nuisance. It is noted
that this 2016 modelling did not include the proposed Upper Mundic Gully TSF disturbance area
however the proposed location of the Upper Mundic Gully TSF is located further away from potentially
affected receptors than other mine features that were including in the modelling. Based on the
topographical profile of the area there is no line of site between the Upper Mundic Gully TSF and
potential receptors.
As with other mine features the likelihood of the Upper Mundic Gully TSF impacting sensitive receptors
is greater in the construction phase associated with truck movements than the operational phase.
Potential noise generation sources from TSF are restricted to discharges from pumps and Light Vehicle
movements. It is considered unlikely that the Upper Mundic Gully TSF will have an impact on the
sensitive receptors provided recommended mitigation measures from the Heritage Minerals EMP are
implemented.
6.5.3. Management Practices
The amendment does not propose any changes to noise impacts, and noise will continue to be
managed in accordance with Schedule D – Noise. Existing mitigation controls will be implemented to
ensure compliance with the EA conditions.
The Heritage Minerals Noise and Vibration Procedures provides standard controls to assist in
compliance with the site EA and, AS 2436 ‘Guide to Noise Control on Construction, Maintenance and
Demolition Sites’ and the QLD Environment Protection (Noise) Policy 2019. These include:
• Temporary acoustic enclosures and portable screening will be used where appropriate for
activities such as concrete sawing, impact drilling and other stationary high noise activities;
• TSF construction works will not occur between 6AM-6PM and no works will occur at night;
• The TSF construction methodology is typical to the industry and will require the use of
excavators, haul trucks, graders and water trucks;
• A 35km/h speed limit is in place for all vehicles;
• Plant and vehicles used intermittently will be shut down in intervening periods or throttled down
to a minimum;
• Care will be taken in moving large objects and materials to avoid causing peak noise events,
including materials from a height into a truck;
• Loaders and bobcats fitted with articulated buckets will be rubber lined at the contact points to
ensure that noise levels are minimised during release of materials;
• Notification letters will be provided to potentially noise or vibration effected premises and
accessible contact details are available for complaints for Council and public;
