SEDIMENT & EROSION MANAGMENT PLAN

 

 

 

 

 

SEDIMENT AND EROSION CONTROL MANAGEMENT PLAN: °

e OBJECTIVE:
To minimise erosion on site and ensure sediment is not washed down to the receiving waterways due to construction e
activities

 

e LEGISLATION:

Prior to the commencment of any construction activities the following measures
shall be incorporated:

Provide education of site personnel

Set up action plans as a precaution in case of disturbances occuring

especially after an unexpected strong rainfall event

Provide regular inspection and maintenance of all structures including the

temporary structures.

 

 

Environment Protection Act 1994
Environmental Protection Water Policy 1997
The Integrated Planning Act 1997

« RESPONSIBILITY:
The responsibility for all measures regarding the sediment and erosion control during construction shall be with the
CONTRACTOR. The contractor shall appoint one staff member, ideally the foreman to be responsible for:

*“the location of drain paths such as swales and trenched, cut off swales, catch drains and perimeter banks. All of
these measures shall ensure the runoff is directed to the sedimentation basin during construction.

“**the waste and wash down of materials and goods in particular concrete and cement shall be separated, set to dry
and disposed of

“installation and maintenance of the sediment control fences all around the perimeter as shown in plan

***control of fences, sandbags and bales as well as the sedimentation basin after each rainfall event

“**control of the entry/exit path and the mini ition of sediment transfer to the street in particular control of concrete

and earthmoving vehicles

‘supervise other members of staff and lead by example

‘ensure enough litter collection devices are provided for the collection of daily litter such as cans, bottles, paper,

butts and also building material cut offs.

‘ensure all stockpiles for both incoming and outgoing goods in particular soils and sands are clearly marked and not

blocking drain paths and kept neat and clean.

‘control the flow path of stormwater at all times during construction and use swales, sandbags, bales and other

measures to ensure the runoff is directed to the sedimentation basin at all times.

 

« ACTIONS:
In case of major rainfall events the following action plan shall be followed and responsibly looked after by the
CONTRACTOR:
CUT—OFF DRAIN ALONG CONTOUR — LONG TERM
*““DON'T WAIT UNITL IT IS TOO LATE! STOCKPILES ONLY (GRADE AT 1

be on site during the rainfall period and monitor the drain paths. Redirect where required.
“check the fences after every rainfall and replace the fences where required. Check and replace all barriers,
bales, sandbags and temporary swales, cut off drains and trenches where required.
clean out sedimentation material as soon as the moisture content allows it.
check the receiving pit and improve the barriers if required.
"REMEMBER: EACH RAINFALL IS THE EVENT TO ACTIVELY WATCH AND CONTROL THE RUNOFF!
