                                                                                          ADG Consulting Pty Ltd


7        Noise & odour management
7.1      Responsibility
         The Project Manager is responsible for ensuring the appropriate management of noise and odour during
         dewatering operations.
7.2      Operational policy
         To minimise noise and odour emissions generated from the site during dewatering.
7.3      Performance criteria
         The appropriate criteria to measure the performance of dewatering management at the site are provided
         below.
         1.    No noise or odour related complaints received from neighbouring residents or the community.
         2.    No degradation of air quality due to fumes or odours emanating from the dewatering process.
7.4      Implementation strategy
         Noise and odour emissions will be managed as described in the following sections.
7.4.1 Noise
         All dewatering equipment must be operated appropriately and maintained in good working order. All
         dewatering systems and plant must be fitted with the appropriate noise reduction equipment to comply
         with the performance criteria. Non‐complying dewatering plant will be replaced or repaired as necessary.
7.4.2 Odour
         All dewatering plant must be fitted with the appropriate emission reduction devices. Where practicable,
         all dewatering plant will be sealed to prevent the release of odours to the atmosphere. Fine mist odour
         control sprays will be applied to reduce offensive odours if complaints are received from neighbouring
         residents.
7.5      Monitoring
         An inspection of the site and dewatering equipment shall be undertaken daily by the Site Manager to
         identify the following:
              Excessive noise being generated by the dewatering systems and plant; and
              Strong or offensive odours being generated by the dewatering equipment and/or extracted
               groundwater.
7.6      Reporting
         Reporting will be undertaken as described in Section 6.7 of this report.
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.
