               CURRENCY PERIOD
               2.     The Currency Period for this development approval lapses if the development has not
                      substantially started by 4 April 2026, unless an application to extend the currency period is
                      approved by Council.
               PRIOR TO COMMENCEMENT OF WORKS
                      Engineering
               3.     Prior to the Prestart Meeting, submit and have approved by Council an amended Dewatering
                      and Acid Sulfate Management Plan. The document is to be prepared and certified by a
                      suitably qualified Registered Professional Engineer Queensland (RPEQ) and demonstrate
                      how Acid Sulfate affected water encountered during excavation will be treated and disposed
                      of. The following specific amendments are to be included:
                      a.      The DMP states that the shoring design is provided in Appendix C – however only the
                              civil engineering plans are provided. Include plans which show the location and type of
                              temporary shoring, groundwater spears, treatment and monitoring equipment location
                              and space requirements. Why do the structural engineering plans (provided
                              separately) only show shoring on 3 sides of the excavation? The type of CFA piling
                              (contiguous or secant) should also be stated on plan.
                      b.      Remove references to ‘steel sheet piling’ on page 10 and refer to CFA secant piling.
                              Please note that the references should reflect the proposed method or the alternate
                              method chosen by the civil engineer.
                      c.      Update section 6.5.2 and 6.5.3 (Water Quality Monitoring) to include continuous
                              monitoring of pH and dissolved oxygen at the release point from the treatment system.
                              Total iron and aluminium are to be sampled where identified in the document as ‘if
                              required’.
                      d.      Update the figure in Appendix A to also show the stormwater network and specifically
                              the stormwater pit which the dewatering system will discharge into and the outlet
                              headwall.
                      e.      Update section 6.4.3 to identify that discharge is to the stormwater network prior to
                              entering the canal system.
                      f.      There seems to be plenty of room in the frontage of the site for establishing a
                              groundwater monitoring bore outside of the excavation and shoring system in which to
                              monitoring groundwater drawdown and quality. Update the monitoring section of the
                              DMP to incorporate such a monitoring location.
                      g.      Section 7 (Noise) is to be updated to refer to the default noise standard for pumps in
                              Section 440T of the EPA Act. The EEP (Noise) objectives currently referenced are
                              long-term objectives rather than a specific enforceable standard.
