    Water quality
    39.   The site must be provided with a stormwater drainage system connecting to a lawful
          point of discharge. The works must include in particular:
          a.    Water quality treatment features that achieve the following pollutant reduction
                targets as measured by a MUSIC model developed in accordance with the Water
                by Design MUSIC modelling guidelines;
          b.    the use of gravity stormwater drainage and not surcharge pits;
          c.    A stormwater quality treatment system must be provided for the development
                that achieved 80% reduction in Total Suspended Solids, 60% reduction in Total
                Phosphorous, 45% reduction in Total Nitrogen compared to an unmitigated
                scenario. The works must be undertaken in accordance with an Operational
                Works approval and the Water by Design Guidelines.
    40.   All stormwater quality treatment devices must be maintained in accordance with the
          Water by Design (2009) - Maintaining Vegetated Stormwater Assets (Version 1). A
          copy of this document must be retained on the site together with the approved
          Operational Works drawings for the stormwater quality treatment system and a detailed
          life cycle costing of the system attached as an addendum. Records of all maintenance
          activities undertaken must be kept and made available to Council upon request.
    41.   Any proposed Community Management Statement required for the development must
          include the Water by Design (2009) – Maintaining Vegetated Stormwater Assets
          (Version 1) document and must include the full cost of maintaining the system in
          accordance with that document.
    42.   Operating rainwater collection and stormwater harvesting tanks must be provided as
          shown identified in section 6.2 of the Engineering Report & Stormwater Management
          Plan report For Proposed Residential and Commercial Tenancies at 30-32 Doonella St
          (A6035/21/ENG/RevB). The tanks must be provided in accordance with an Operational
          Works approval.
    43.   Certification must be submitted to Council from a qualified person* which certifies that

          accordance with the requirements of this Decision Notice.
          *(Refer to Advisory Note)
    Acid Sulfate Soils
    44.   All waters, including stormwater runoff, groundwater seepage and leachate must
          achieve the following quality prior to release from the site at all times:
          a.    a pH range of 6.5-8.5 pH units;
          b.    50mg/L maximum total suspended solids concentration;
          c.    0.3mg/L maximum total iron concentration;
          d.    0.2mg/L maximum total aluminium concentration; and
          e.    no visible plume at either the point of release from the site or within a waterway.
    ENVIRONMENTAL HEALTH
    Waste Storage
    45.   The developer must provide waste storage and disposal facilities in accordance with
          Planning Scheme Policy 9, Waste Management, including an external imperviously
