PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                              6 SEPTEMBER 2016


          Acid Sulfate Soils
    46.   Where excavations of non-imported soils below the elevation of 5m AHD are
          necessary for construction, the application for Operational Works for Bulk
          Earthworks, Stormwater and /or Landscaping must demonstrate and include
          certification from a suitably experienced and qualified geotechnical engineer of
          methods necessary to ensure construction and operation of the development:
          a.    is consistent with Queensland Acid Sulfate Soil Technical Manual: Soil
                Management Guidelines; and
          b.    will not result in the release of acid or associated metals; and
          c.    will not cause localised lowering of groundwater.
          Erosion and Sediment Control
    47.   Prior to the completion of the development, all site surfaces must be effectively
          stabilised. For the purpose of this condition, an effectively stabilised surface is
          defined as one that does not, or is not likely to result in visible evidence of soil loss
          caused by sheet, rill or gully erosion or lead to sedimentation, or lead to water
          contamination.
    WATER QUALITY
          Noosa Springs Lake Management
    48.   The application for operational works approval must demonstrate, through water
          balance calculations prepared by a hydraulic engineer, that the hydraulic residence
          time of the Noosa Springs Lake System will not be reduced as a result of stormwater
          management on the site.
    49.   Where stormwater runoff from the site will enter the Noosa Springs Lake System,
          Quarterly monitoring of stormwaters directed from the development to the Noosa
          Springs Lake System. Monitoring must be undertaken by a suitably qualified person
          using NATA accredited methods for the following parameters.
              Nitrite plus Nitrate as N (NOx)
              Total Kjeldahl Nitrogen (TKN)
              Total Nitrogen as N (TKN + NOx)
              Total Nitrogen as N
              Total Phosphorus as P
              Reactive Phosphorus as P (Dissolved)
              Reactive Phosphorus – Filtered
          Water quality monitoring results must be retained in electronic form by the property
          owner for a minimum of 5 years and must be made available to Noosa Council on
          request. This monitoring must continue until notified by Noosa Council that it is no
          longer needed.
    50.   During the first 5 years of operation, for a minimum of 5 rainfall events per year,
          stormwater at the following locations and times must be collected and sampled for
          Total Nitrogen, Total Phosphorous and Total Suspended Solids using NATA
          accredited methods.:
          50.1. The release point from Precinct E2 for all waters directed to the Noosa Springs
                lake system.
          50.2. At monitoring point W6 shown on Plan A – Water Quality Monitoring Locations
                Noosa Springs by Jelliffe Environmental (Qld) Pty Ltd.
