CONSTRUCTION PHASE - SURFACE & GROUND WATER QUALITY

                                             Presence of dark grey sands or clays (e.g. mangrove mud);
                                             Presence of very clean water or clean bluish water;
                                             Soils which exhibit sulphurous odour; and
                                             Presence of iron (red coloured) stains in water or on soil.
                                  n   Any excavation works consisting of 100m3 or greater which extends below 5m AHD will need to be carried out in
                                      accordance with State Planning Policy 2102 Planning and Managing Development Involving Acid Sulfate Soils. Appropriate
                                      testing and supporting documentation prepared by a suitably qualified specialist shall be submitted to Council for approval
                                      prior to obtaining a Development Permit for Operational Works;
                                  n   Should exposure of acid sulfate soils occur, the following steps should be implemented:
                                             Stop excavation in the area; and
                                             Advice should be sought from an appropriate qualified professional on specific treatment methods (e.g. liming of the
                                             affected material).
                                  n   All stockpiles to be located in accordance with Stormwater Management Plan / Sediment and Erosion Control Plan
                                      Appendix A;
                                  n   Where chemical treatment is required, chemicals will be kept away from sensitive areas and the selected chemical should
                                      be frog friendly such as BioactiveTM Herbicide, Roundup or Weedmaster Herbicide. Broad scale spraying is not permitted;
                                  n   Permanent control measures are to be installed as soon as possible after completion in each construction area. Permanent
                                      measures (e.g. vegetated buffers, bio-retention trenches, constructed wetland system) are to be installed as outlined in the
                                      Stormwater Management Plan / Sediment and Erosion Control Plan (Appendix A).

Monitoring                            A daily site checklist will be used by the Construction Foreman to ensure that contractors understand and perform the
                                      required management actions. The checklist to be utilised is included as Appendix C of the Stormwater Management Plan /
                                      Sediment and Erosion Control Plan (Appendix A);
                                  n   Daily visual inspections of excavation works for PASS & ASS;
                                      Monthly audit and review of implemented temporary control devices and site erosion and sediment control procedures by
                                      the Environmental Officer;
                                      Monthly water quality monitoring during the construction phase to be conducted by the Environmental Officer, as per the
                                      monitoring schedule, methodology and locations outlined in Stormwater Management Plan / Sediment and Erosion Control
                                      Plan; (Appendix A). The following water quality parameters are to be monitored:
