Reference Document - Dewatering Management Plan (For Stamping) MCU25/0053 & OPW25/0074

                                                                                                              ADG Consulting Pty Ltd

                              must ensure that workers are not exposed to noise that exceeds the exposure standard for noise. The
                              exposure standard for noise is defined in the Work Health & Safety Regulation 2011 (QLD) as LAeq,8h of
                              85 dB(A) or an LC,peak of 140 dB(C). As such, it is considered appropriate to adopt these exposure
                              standards to assess average and peak noise generated at the site with the potential to affect exposure
                              levels of nearby sensitive receptors (noting there will be some attenuation between source and receptors
                              and actual noise experienced by receptors would need to be measured at the receptor location).
                      7.6     Reporting
                              The Site Manager must keep records of complaints, monitoring records (including continuous noise
                              monitoring data, where required to be monitored), and corrective and preventive actions/methods
                              employed for noise abatement. These records must be available on‐site at all times and submitted to NSC
                              by the Site Manager upon request.
                      7.7     Contingencies
                              If noise levels consistently exceed the performance criteria, temporary acoustic barriers will be
                              constructed around the offending dewatering systems and plant. Odour control sprays will be applied as
                              necessary to mask odour emissions if complaints are received from neighbouring residents. This may
                              include the direct injection of deodorisers to the groundwater treatment system.
