                     Install a temporary construction entry/exit sediment trap at all site accesses to
                      minimise mud and sediment from the site being tracked onto public road, particularly
                      during wet weather or when the site is muddy.
                     Install and maintain appropriate sediment fences around construction areas
                            Divert clean stormwater runoff, using catch drains, around construction areas
                                to existing or new stormwater drainage system.
                            Install sandbags and other pollution containment devices around stormwater
                                drains and any other locations where required to prevent sediment entering
                                the trunk stormwater system.
                            Cover open earth/soil areas progressively (with concrete slabs and pavements
                                or mulch) to minimise areas of bare earth/soil.
                            Any stockpiles of excavated soil and demolition / construction waste must be
                                located where risk of erosion and sediment is minimal, and must be protected
                                from wind and water erosion.
                     Implement and maintain appropriate control measures such as catch drains and
                      sediment fences to prevent ponding of stormwater or discharge of stormwater from
                      the site to adjacent properties.
                     Provision of spill / pollution control equipment that is readily accessible to clean up
                      spills and leaks.
                     Ensure spill/pollution control measures are available and maintained in working
                      condition.
                     Sediment contained by the sediment control devices such as sandbags, sediment fences
                      and containment bunds must be frequently removed and placed in a controlled area.
                     Implement an inspection schedule for any spill or leaks of any potential polluting areas
                      or activities.

5.5.4 Erosion Sediment Control Management Goals

          Licenses, approvals, permits and inspection reports are in order.
          Sediment or pollution control devices such as sandbags, sediment fences and containment
           bunds are in place, maintained and effective.
          Spill/ pollution control equipment is readily accessible at designated locations.
          No accumulated sediment is contained by the sediment control devices such as hay bales,
           sediment fences and containment bunds.
          No sediment exceeding a depth of 300mm in the pollution control devices (e.g. silt trap).

5.5.5 Erosion and Sediment Control Implementation Program

          Licenses, permits or approvals for each environmentally relevant activity must be obtained
           prior to the commencement of the particular activity.
          Appropriate control measures such as sediment fences, temporary construction entry/ exit
           sediment traps, pollution containment devices (e.g. sandbags), stormwater diversion and
           administrative controls must be installed and established prior to commencement of the
           earthworks and construction activities.
          Pollution control devices such as spill control equipment must be inspected on a regular basis
           (at least weekly).
          Other sediment and pollution control equipment such as containment bunds, hay bales and
           sediment fences must be inspected on a regular basis (at least daily).
