Stormwater Management Plan

     –    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.

6.4.4 Erosion and 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).

6.4.5 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).
•    Inspection for any leaks, spills or potential contaminating activity must be performed on a regular
     basis (at least daily).
•    Remove accumulated sediment or other contaminants from sediment/ pollution control devices on
     a regular basis.
•    All erosion and sediment control measures must be inspected within 24 hours of expected rain and
     within 18 hours of a rainfall event.

6.4.6 Responsible Person or Organisation

The contractor shall be responsible for the implementation and maintenance of the Erosion and
Sediment Control Measures.
