               62.    Prior to issuing of a final compliance certificate, council must receive evidence that the results
                      for the in-situ hydraulic conductivity testing conducted in accordance with FAWB PRACTICE

                      Erosion and Sediment Control
               63.    A ‘for construction’ Erosion and Sediment Control Plan (E&SCP) must be provided to
                      Council’s Delegate at least 2 weeks prior to the on-site pre-start meeting and prior to works
                      commencing. The E&SCP must:
                      a.      be prepared by a suitably qualified and experienced professional;
                      b.      relate to each phase of the works (including clearing, earthworks, civil construction,
                              services installation and landscaping) and detail the type, location, sequence and
                              timing of measures and actions to effectively minimise erosion, manage flows and
                              capture sediment;
                      c.      be consistent with current best practice standards to the extent that the standards are
                              not inconsistent with the conditions of approval and taking into account all
                              environmental constraints including erosion hazard, season, climate, soil, and
                              proximity to waterways;
                      d.      provide sufficient detail regarding the manner in which compliance with all conditions
                              of this permit relating to E&SC is to be achieved;
                      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
               64.    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.
