Erosion Sediment Control Plan




3                 Erosion and Sediment Management
3.1               Methodology
The Contractor’s proposed erosion and sediment control methodology is to be implemented in four distinct
phases in accordance with construction activities being undertaken.
          Phase 1 – Prior to Construction commencement
          Phase 2 – Bulk Earthworks
          Phase 3 – Civil Construction
          Phase 4 – Post Construction
Sediment basin/s is/are to be established, as require, prior to works commencing in the basin’s catchment
area.
The site is to be filled in a cellular fashion, in that the external fill batters are to be filled and stabilised first
prior to the infilling of the fill areas. The entire earthworks area will be managed by the Contractor in a logical
and reasonable sequence.

3.2               Soil and Stockpile Management
All reasonable and practicable measures must be taken to obtain the maximum benefit from existing topsoil.
Viable topsoil is to be stockpiled in long low flat mounds to facilitate the survival of seed and micro-
organisms vital for the topsoil.
Stockpiles of erodible material that has the potential to cause environmental harm, if displaced, must be:
          Appropriately protected from wind, rain, concentrated surface flow and excessive up-slope
           stormwater surface flows.
          Located at least 2m from any hazardous area, retained vegetation, or concentrated drainage line.
          Located up-slope of an appropriate sediment control system.
          Provided with an appropriate protective cover (synthetic, mulch or vegetative) if the materials are
           likely to be stockpiled for more than 28 days.
A suitable flow diversion system must be established immediately up-slope of a stockpile of erodible material
that has the potential to cause environmental harm if displaced, if the up-slope catchment area draining to
the stockpile exceeds 1500m 2.

3.3               ESC Installation sequence
Prior to land disturbance

 Item                                                        Removed
 Mark out initial limits of disturbance / mark out No Go
 Zones
 Entry / Exit installed                                      Upon site completion
 Install sediment weir                                       After construction of Sediment Basin
 Clear sediment basin and stockpile areas
 Install sediment fence to stockpile areas                   After stockpile removal
 Install Sediment Basin and stabilised outlet                Upon site completion
 Install clear water diversion and repair as required
