“Specialist services and practical solutions”



       The applicant has provided an Interim Stormwater Management Plan (ISWMP) prepared by
       TOPO for the site as a whole (refer Attachment 8). At this stage, the ISWMP needs to be
       considered in context with the currently approved SWMP prepared by Covey (M25-004Rpt,
       dated February 2025 (refer condition 15 – Attachment 1A). Further, the completed SWMP will
       be provided by TOPO as soon as possible. It is expected that the finalised TOPO SWMP will
       replace the current Covey SWMP under the approval.

       It is stated by TOPO the objective is to provide an ISWMP for the site, taking into consideration
       the current conditions and future works, and identify how runoff will be managed to comply
       with the relevant guidelines and licence conditions. The consultant advises that once the layout
       for the future works, particularly the development of the northern portion of the site, is
       confirmed, hydrologic and hydraulic modelling will be undertaken to size all required drainage
       features. The SWMP addresses surface water only and does not include the management of
       groundwater or leachate 8.

       The stormwater management consultant has made a number of recommendations for the
       existing operation across the site and the design of the northern precinct redevelopment:
           • assess the catchments within the active filling zones and ensure all disturbed areas are
               being directed to an appropriately sized sediment control
           • inspect the eastern boundary on the edges of Catchments 12 and 22 and ensure all
               runoff has been managed in accordance with the site permit and discharged at an
               appropriate location
           • implement the recommendations of the TOPO concept design and Covey stormwater
               management plan for the upgraded HES basin at SW2
           • investigate options for the treatment of runoff from low erosion risk areas in the
               northern portion of the NRRC, which is likely to be bioretention systems.
           • Ensure all drainage for the NRRC is designed to convey peak flows associated with the
               1 in 10 year (10% AEP) event per DETSI 2025, or as required to ensure the necessary
               flow rates are conveyed to the HES basin to achieve the annual runoff treatment
               percentage necessary.


       7        Consultation

       While not a requirement under the planning scheme or the Planning Act 2016, the applicant
       has previously undertaken consultation with Kabi Kabi Peoples Aboriginal Corporation about
       proposed improvements at the NRRC. The proposed use of the site as a utility installation is
       consistent with the intended use community infrastructure and is not required to be publicly
       notified. Importantly, the proposed development does not extend beyond the existing
       operational footprint and does not raise any native title issues.

       The proposed composting facility is centrally located within the land and will improve and
       complement the existing organic waste management and processing on the site, without
       causing significant offsite impacts. In the circumstances, there is no need for additional
       community consultation to be undertaken.
