ONSITE EROSION & SEDIMENT CONTROL
OBJECTIVE:

TIME FROM COMMENCEMENT OF DISTURBANCE TO REHABILITATION TO BE <3 MONTHS.
CLEARANCE:

1. PLACE CLEAN WATER DIVERSION AND SEDIMENT BASINS IN PLACE BEFORE COMMENCING
STRIPPING.

2. MINIMISE DISTURBANCE BEYOND EXTENT OF WORK TO 2m (Sm MAXIMUM).
3. SLASH AND STORE GRASS FOR MULCH, STRIP AND STOCK PILE TOPSOIL.

4, MULCH CLEARED VEGETATION FOR RE-USE AND STOCKPILE MULCH AND TOPSOIL AWAY
FROM CONCENTRATED STORMWATER FLOW PATHS.

5. STOCKPILE ON SITE

DIVERT OVERLAND STORMWATER AROUND STOCKPILES BY BUNDS
SILT FENCE IS TO BE PLACED ON DOWNSLOPE OF STOCKPILE
SEPERATE FROM REMAINING VEGETATION AREAS BY MINIMUM 2m

IF STOCKPILES ARE TO BE LEFT FOR 2 WEEKS, COVER WITH GEOFABRIC OR
EQUIVALENT

6. STORE EXTRA MATERIALS FOR EMERGENCY EROSION AND SEDIMENT CONTROL ON SITE
(je. MULCH, GYPSUM, ROCKS, GEOFABRIC, SAND BAGS).

7. IF WATER RELEASED FROM SITE IS, OR IS LIKELY TO EXCEED 50mg\L: TAKE FURTHER
IMMEDIATE REMEDIAL ACTION BEFRE RELEASING WATER.

8. ANY DIVERSION DRAINS WHICH DROP DOWN BATTERS MUST BE GEOTEXTILE LINED

9. EMBANKMENTS OR BATTERS NOT BEING WORKED MUST BE STABILISED IMMEDIATELY THEY
ARE PREPARED.
