               Erosion and Sediment Control
               57.    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
               58.    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:
                      (c) 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.
                      (d) 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.
                            (ii) Ensure clean stormwater is diverted/managed around or through the site without
                                   increasing the concentration of total suspended solids or other contaminants in
                                   the flow and without causing erosion (on-site or off-site). If it is not feasible to
                                   divert all areas discharging clean stormwater around or through the site, the clean
                                   stormwater runoff is managed in the same manner as contaminated stormwater
