                 Stockpiles of soil shall be controlled by sediment fences on the down slope side.
             .
                 Any stockpiles of fine soil material (excludes coarse sandy materials) shall be covered
                 with plastic sheeting and sandbags if there is no requirement to access a stockpile
                 within three (3)days.
             .   Water from the external catchment will diverted around/through the site via established
                 road kerb and channel and stormwater system and not allowed to enter disturbed
                 areas of the site.

             .   Stormwater runoff within the site shall be directed via stabilised swales to silt traps.
             .   Disturbed areas should be progressively stabilised as quickly as possible completion
                 of cell and rehabilitation earthworks.
             .   Stabilise disturbed areas with heavy mulch (50mm thick) to ensure that erosion does
                 not occur in disturbed   areas   within 20 days of inactivity, even though works      might
                 continue later.
