                                                                                     2003/220653

      Sediment and Erosion Control Plan
63.   Detailed staged Sediment and Erosion Control Plans shall be prepared for the site, to the
      reasonable satisfaction of Council and implemented by the owner. The Plans shall be in
      accordance with the Institution of Engineers Australia ‘Engineering Guidelines for Queensland
      Soil and Sediment Control’ (June 1996) and in particular using Checklist No. 3 from that
      document. The Sediment and Erosion Control Plans shall cover all development on site
      (during the construction, establishment and operational phases), ecological restoration and
      remediation works. The methods of controlling erosion and sediment are required to be
      submitted to the Council for approval prior to obtaining a Development Permit for Operational
      Works.
64.   The Sediment and Erosion Control Plans shall also apply to the area of ‘Retained and
      Enhanced Vegetation’ shown on the Vegetation Clearing Plan dated 23.7.04, and shall:
      - identify existing erosion problems, and
      - specify appropriate remedial actions.
65.   All necessary erosion and sediment control devices shall be incorporated within the
      development area of the site.      That is the area shown as ‘Selective Clearing’ on the
      Vegetation Clearing Plan dated 23.7.04.
      Stormwater and Water Quality Management Plan
66.   A Stormwater and Water Quality Management Plan for the site shall be prepared to the
      reasonable satisfaction of Council and implemented by the owner.
67.   The Stormwater and Water Quality Management Plan shall take into account matters specified
      in section 19.4 of the Environmental Protection (Water) Policy 1997.
68.   Key water quality objectives to be reflected in the Stormwater and Water Quality Management
      Plan are for the protection of aquatic ecosystems in the waterways, wetlands and wet
      heathlands of the site and the receiving waters of Noosa Inlet and the Noosa River. The low
      nutrient and pH environment of the wetlands and wet heathlands of the site are the key factors
      in determining appropriate performance targets. Specifically, water quality objectives shall
      include the following performance targets, subject to the constraints of the catchments external
      to the site:
      - Total nitrogen levels – 0.34 mg/l
      - Total phosphorous levels – 0.035 mg/l
      - pH – 4 to 5.
69.   The Stormwater and Water Quality Management Plan shall comply with and address, inter
      alia, the following issues in relation to the construction, establishment and operation phases of
      the development:
      69.1 All necessary stormwater treatment and water quality devices associated with the
           development shall be located within the approved boundaries of the site.
      69.2 During the construction phase, monthly water quality monitoring and monitoring after
           significant rainfall events (at least two per year) shall be undertaken for:
                  suspended solids and turbidity,
                  temperature,
                  salinity,
                  total nitrogen,
                  total phosphorous,
                  pH,

                                                                                    Page 11 of 24
