               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.
                      h. Provide dilapidation reports for neighbouring properties and any other structures or
                         infrastructure identified as being within the estimated cone of depression associated with
                         the groundwater drawdown.
                      Note: Refer to the Acid Sulfate Soils Overlay Code and PSP8 – Natural Hazards for guidance
                      on Acid Sulfate Soils requirements.
               4.     All necessary approvals from external service providers (e.g. Unitywater, Energex) and
                      external parties on which the development works are proposed have been obtained and a
                      copy supplied to Council.
               5.     Copies of the approved plans, duly signed by the consultant Registered Professional
                      Engineer of Queensland (RPEQ) must be provided to Council’s Engineering Officer
                      Construction at the “prestart” meeting.
