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 (5m 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
(i.e. 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.

10. STORE GYPSUM ON SITE FOR MULTIPLE BASIN FILLS.
11, HOLD POINTS FOR ESCP.
* PRESTART MEETING

* SUBGRADE APPROVAL
* FINAL TRIM BASE APPROVAL
