SEDIMENT CONTROL
1. ALL SEDIMENT & EROSION CONTROL MEASURES TO BE IN ACCORDANCE WITH INTERNATIONAL
EROSION CONTROL ASSOCIATION (IECA) AUSTRALIA GUIDELINES AND THE SPECIFICATIONS. THE BASIC
PRINCIPLES ARE TO:
- MINIMISE THE AREA OF DISTURBANCE;
- CONTROL DRAINAGE PATHS UPSTREAM OF SITE AND AT OUTLETS FROM SITE;
- MINIMISE EROSION;
- MINIMISE SEDIMENTATION;
PROGRESSIVELY REVEGETATE AND REHABILITATE THE SITE
2. SEDIMENT & EROSION CONTROL DETAILS SHOWN ARE MINIMUM REQUIREMENTS. IT IS THE
CONTRACTOR'S RESPONSIBILITY TO INSTALL ADDITIONAL CONTROL MEASURES AS DEEMED

THE EROSION & SEDIMENT CONTROL PLAN IS A CONCEPT PLAN DEMONSTRATING
AN APPROACH TO EROSION & SEDIMENTATION CONTROL FOR THE SITE. IT IS THE
CONTRACTORS RESPONSIBILITY TO PROVIDE AN EROSION & SEDIMENT CONTROL
DESIGN AND A COMPLETED DESIGN CERTIFICATE PRIOR TO COMMENCEMENT OF
WORK. CERTIFICATION MUST BE UNDERTAKEN BY A SUITABLY QUALIFIED,
EXPERIENCED PROFESSIONAL NOT DIRECTLY EMPLOYED BY THE PRINCIPAL.
