Negotiated Report (Representations made) MCU24 0125, OPW24 0150 & RAL24 0021 (As Published) · MCU24/0125

                      e.      include details of proposed flocculants and automatic dosing systems for sediment
                              basins, including jar testing results. Demonstrate the suitability of the proposed
                              flocculant having regard to the downstream receiving environment and water quality;
                              and
                      f.      include the results of all soil investigations undertaken for the site and on which the
                              E&SCP is based.
               41.    A construction hold point inspection with a Council delegate is required following the removal
                      of existing ground cover (i.e., grass) and prior to the commencement of the bulk earthworks.
                      At the time of the inspection, the erosion and sediment controls prescribed by the supervising
                      RPEQ or CPESC must be installed in accordance with current best practice standards.
                      Written certification from the supervising RPEQ or CPESC must be provided to Council
                      certifying that the on-site controls satisfy the conditions of this approval.
               42.    A logbook of all Erosion & Sediment Control (E&SC) activities must be prepared for the
                      development and maintained until the completion of the works. The logbook must be made
                      available to the Council upon request, within five (5) business days of the date of the request.
                      Each entry into the logbook must document the extent of works, the date the works occurred
                      and any observations or notes. It is expected that logbook entries may include, but are not
                      limited to:
                      a.      amendments to the E&SC plan(s);
                      b.      maintenance of any erosion and sediment controls;
                      c.      emptying of detention basins (with Discharge Authority Certificates);
                      d.      inspections by the supervising RPEQ or CPESC; or
                      e.      any breaches of sediment exiting the site.
               43.    Prescribed Water Contaminants (as defined in the Environmental Protection Act 1994) must
                      not be released from the site or to waters within the site, or be likely to be released should
                      rainfall occur, unless all reasonable and practicable measures are taken to prevent or
                      minimise the release and concentration of contamination. These measures must be
                      designed, implemented and maintained in accordance with “Best Practice Erosion and
                      Sediment Control” published by the International Erosion Control Association (Australasian
                      Chapter) (IECA, 2008), to the extent that such measures and practices are also consistent
                      with the following:
                      a.      Minimise erosion:
                              i.        Restrict the extent of clearing to that necessary for access to and safe
                                        construction of the approved works;
                              ii.       Protect vegetation in all other areas of the site;
                             iii.       Minimise the duration of soil exposure by undertaking land clearing and
                                        stabilisation according to the rainfall erosion hazard as specified in IECA (2008)
                                        Tables 4.4.2 and 4.4.7
                             iv.        Prior to either the approval of the plan of survey for the development or
                                        commencement of use, all site surfaces are to be effectively stabilised using
                                        methods that will continue to achieve effective stabilisation in the medium to
                                        long term. For the purpose of this condition, an effectively stabilised surface is
                                        defined as one that does not or is not likely to result in visible evidence of soil
                                        loss caused by sheet, rill or gully erosion or lead to sedimentation, or lead to
                                        water contamination.
                      b.      Manage concentrated stormwater flows:
                              i.        Implement drainage and erosion control measures (including contingency
                                        measures), prior to rainfall, which prevent or minimise rill erosion and gully
                                        erosion.

                                                                                                           Page 31 of 39
