PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                            8 NOVEMBER 2016


          Stormwater Drainage
    24.   The site must be provided with a stormwater drainage system connecting to a lawful
          point of discharge. The works must be undertaken in accordance with an Operational
          Works approval issued in accordance with The Noosa Plan and the Queensland
          Urban Drainage Manual.
    25.   The stormwater detention system for the development must achieve the outcomes
          detailed in Section 3.5 of the Stormwater management Plan for Noosa Energy Centre
          – 140-142 Eumundi Noosa Road, Noosaville for Denmac Nominees Pty Ltd by
          Lambert & Rehbein Engineers Managers Scientists dated 14 July 2016 reference
          number B16239CR002.
    26.   A stormwater quality treatment system must be provided for the development to
          achieve pollutant reduction targets of 90% reduction in gross pollutants, 80%
          reduction in Total Suspended Solids, 60% reduction in Total Phosphorous and 45%
          reduction in Total Nitrogen.
    27.   The Operational Works application must be supported by a MUSIC model that
          includes water quality treatment nodes endorsed by Stormwater Australia or their
          delegate to meet the Stormwater Quality Improvement Devices Evaluation Protocol.
          Evidence of the endorsement of the product must be provided with the Application for
          Operational Works.
    28.   Any proprietary stormwater quality improvement product must be:
          a.    designed and installed in accordance with its relevant Technical Design Guide;
          b.    incorporate adequate high flow bypass for peak flows that exceed the design
               capacity of the system;
          c.   include energy dissipation to prevent resuspension of accumulated sediment;
          d.   include for activation of any necessary components following key rainfall events
               for the device (i.e. for Stormwater 360, the design must include for activation of
               the siphon following a 5mm rainfall event over the catchment area.
    29.   All proprietary stormwater quality treatment devices must be routinely checked,
          serviced and cleaned in accordance with the manufacturer’s recommendations.
          Records of all maintenance activities undertaken must be kept and made available to
          Council upon request. Where replacement cartridges or other necessary components
          for the system become unavailable, an alternative system is required to be retrofitted
          into the development to achieve an equivalent pollutant reduction outcome.
    30.   A copy of a signed supply agreement between the site operator and the stormwater
          filtration system supplier for the replacement and maintenance of treatment
          components of the proprietary stormwater quality treatment devices must be provided
          to Council prior to issue of Operational Works Approval. The supply agreement must
          be for at least 10 years.
          Stormwater Harvesting
    31.   Operating stormwater harvesting tanks must be provided for the development. The
          tanks must be provided in accordance with a Building Works for above ground tanks,
          or Operational Works Approval for below ground tanks and must include in particular:
          a.   a minimum capacity of 5,000L to deliver the outcome proposed in item 9 of the
               letter from Lambert & Rehbein Engineers Managers Scientists to Urbis dated
               23 September 2016 with reference number B16239CL002.
          b.   re-use of harvested rainwater for internal non-potable uses and outdoor uses.
