Minor Change Existing Approval MCU21/0228.02 & OPW21/0364.02 [As Published]

                      e.      The property access must be located a minimum of 1m clear of existing power poles,
                              streetlights or other signage. The developer is responsible for any necessary relocation
                              of existing services to provide this clearance and must contact the relevant service
                              authorities and comply with their requirements in relation to these works.
                      Stormwater Drainage
               65.    Appropriate scour protection must be provided at the outlet of all stormwater pipes including
                      temporary outlets.
               66.    Works associated with this permit must not adversely impact on the existing drainage
                      conditions on other properties (eg by blocking or interfering with natural overland flows).
               67.    Construction of all internal stormwater drainage works must comply with the relevant
                      section/s of Australian Standard AS/NZS 3500.3.
                      Erosion and Sediment Control
               68.    Prescribed Water Contaminants (as defined in Schedule 10 of Environmental Protection
                      Regulation 2019) 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.       For areas of the site which drain to a sediment basin, implement drainage and
                                       erosion control measures prior to rainfall which prevent or minimise rill erosion
                                       and gully erosion
                              ii.      For areas of the site which do not drain to a sediment basin, implement drainage
                                       and erosion control measures prior to rainfall (including contingency measures)
                                       which prevent or minimise erosion, including rain drop erosion, chemical erosion,
                                       rill erosion and gully erosion
                              iii.     Prior to the final inspection for the development, all site surfaces must be
                                       effectively stabilised using methods which have achieved effective short-term
                                       stabilisation and which 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.       Prior to each rainfall event ensure concentrated stormwater flow paths are
                                       provided with capacity in accordance with IECA (2008) Table 4.3.1 and are
                                       structurally stable in all rainfall events for the following sources:
                                       (a)        From stormwater catchments upslope of the area of disturbance
                                             which are either stable or external to the site, ensure stormwater is diverted
                                             or managed either:
                                             i.    around the site or through the site without causing erosion and
                                                   without contaminating the flow; or
                                             ii.   if it is impractical to convey the flows around or through the site,
                                                   convey the flows into appropriately sized sediment basins without
                                                   causing erosion
                                       (b)   From all disturbed areas of the site to sediment basin(s) without causing
                                             erosion
