Att 3_CMP - Final

    1. PURPOSE
        This procedure is required to address the management of environmental impacts associated
        with drainage impediments and diversion channel developed within the project area.

        The measures outlined in this procedure will ensure compliance with local, state and federal
        authorities and legislative requirements. They aim to minimum erosion and control
        sediment movement on-site using sound environmental methods and procedures.

        Potential impacts due to drainage modifications associated with construction activities may
        include:

           •     Changed surface water flows into creeks,
           •     Contamination of surface water,
           •     Changed rates of erosion and deposition,
           •     Increased sediment loading,
           •     Localised flooding.

        This procedure also detailed the physical structures and devices which the control measures
        may be compiled, and the circumstances in which they could be used. Detailed regarding the
        methods for installation are also included.

        The final implementation of erosion and sedimentation controls will be determined by on-
        site conditions prior to the commencement of each section or works. As far as practical,
        these controls will be implemented before starting any earthworks.

    3. PROCEDURE OVERVIEW
        Activities that expose areas of bare earth, causing the potential erosion, and thereby
        contamination of receiving bodies, include;

           •     Cut and fill earthworks activities (incl. stockpiles),
           •     Vegetation removal,
           •     Topsoil stripping,
           •     Demolition, and
           •     Service Relocation.

        The Environmental Protection (Water) Policy 2009 provides the framework for controlling
        and regulating the discharge of pollutants into all waters.
