PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                                  12 MARCH 2019


           65.4. Location of inspection and monitoring points shown clearly on the plan
           65.5. A schedule or timetable for the proposed regular inspection, maintenance and
                 monitoring of the devices.
           65.5 For proprietary products a maintenance contract of a minimum 10 years to
                demonstrate that the proprietary product shall be maintained as per the
                manufacturers specifications.
           65.6 Details of the location and method for maintenance of any proprietary products
                to demonstrate that collected pollutants and nutrients shall be disposed of in
                accordance with relevant legislation.
                Records of all maintenance activities undertaken must be kept and made
                available to Council upon request.
     72.   The fire-fighting demand on Unitywater’s water supply system from the development
           must comply with Unitywater requirements and industry standards.
C.   Delete conditions 44, 45 and 80.
D.   Include the following new condition
     81.   Any proprietary stormwater quality improvement device included to achieve the
           required stormwater quality Management Objectives specified in Section 4 of the
           Girraween Stormwater Management Plan, must demonstrate only be granted an
           Operational Works Approval on the following provisions:
           a.   A suitably qualified and experienced professional must provide independent
                verification that the parameters within the node for the device in MUSIC
                modelling have been tested and verified as per Stormwater Australia (2018)
                Stormwater Quality Improvement Device Evaluation Protocol. Version 1.2
                December 2018 to achieve the predicted outcomes in the MUSIC model for the
                development. For the purpose of this condition, the suitably qualified and
                experienced professional must be able to demonstrate a minimum 10 years
                urban stormwater testing and modelling experience and be verified in writing by
                Stormwater Australia as having an appropriate reputation and track record
                within the stormwater industry to provide such independent advice.
           b.   Where testing to achieve the certification of the proprietary stormwater quality
                improvement device is from an area with rainfall intensities and patterns that
                are statistically inconsistent with the region of the Noosa Shire that the device is
                to be installed, and / or the size of the development the device has been tested
                on is more than 2500m2 smaller than the development the device is proposed
                to service, the following additional conditions apply:
                i.    The proprietary stormwater device treatment train must be tested and re-
                      verified in accordance with the Stormwater Australia (2018) Stormwater
                      Quality Improvement Device Evaluation Protocol. Version 1.2 December
                      2018. A suitably qualified and experienced professional, as verified by
                      Stormwater Australia must use the results from the onsite testing to re-run
                      the MUSIC node for the proprietary devices and confirm whether or not
                      the required pollutant reduction efficiencies of 80% reduction in Total
                      Suspended Solids, 60% reduction in Total Phosphorous and 45%
                      reduction in Total Nitrogen for the overall development are delivered.
                ii.   Where the field results and re-run MUSIC node demonstrate the required
                      pollution reduction efficiencies for the development are not met, the
                      applicant must implement additional measures to achieve the required
                      pollution reduction targets. The additional measures must include, in
                      order of priority, elevated maintenance, and then increased treatment
                      capacity of the stormwater quality improvement devices. Following

                                                                                   Page 17 of 116
