7.6.2 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 and the ancillary infrastructure, 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. 7.6.3 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 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; ∕ Complaints will be documented in a complaint register and following complaints, identifying the source of noise or vibration complaint and modify the work practices to reduce noise levels, e.g. use of smaller equipment where available or rescheduling of works. The complainant must be notified of measures undertaken to minimise noise or vibration impact. As required under the Regional Interests Development Approval (RIDA) PLA permit, complaint response will be submitted to Department of State Development, Infrastructure, Local Government and Planning (DSDILGP); and ∕ Temporary movable noise barriers or hoarding will be installed where complaint instigation warrants further control beyond management of intensity of site activities.
