5.3.4   Water Quality Monitoring and Inspections
        To ensure that the water quality objectives are being met during the construction phase of the
        development water quality monitoring shall be conducted at a monitoring station downstream of the
        works. Water quality monitoring shall use a calibrated probe and/or sampling and testing at a NATA
        registered laboratory.

        Location:         Monitoring Station downstream of the proposed works.

        Parameters:       Site discharge criteria.

        Frequency:        Following at least 30 mm of rainfall in a 24 hour period.

        The contractor shall be responsible for the inspection and maintenance of all sediment and erosion
        control devices. Additional controls and review of existing controls shall be undertaken in response to
        the results of the above-mentioned monitoring program.

5.3.5   Reporting
        An inspection report shall be written by a suitably qualified and experienced scientist/engineer
        following each water quality monitoring episode. The report shall include at least the following
        information.

                Name, address and real property description for the development site;
                Council file reference number (if known);
                Monitoring locations;
                Performance criteria;
                Results for each monitoring location, identifying any breaches of performance criteria, and
                Recommended corrective actions to be taken and additional sediment and erosion controls,
                 if required.

        Inspection reports shall be provided to the contractor for their action and compilation in an on-site
        register. If the above-mentioned performance criteria are exceeded and results from the downstream
        monitoring stations show significant deterioration from upstream results (if applicable), the
        contractor shall implement all recommendation of the inspection report within (1) working day of
        receipt of the report.

5.4     Operational Phase

        The following sections provide details of the stormwater quality improvement devices (SQID’s)
        proposed for the operational phase of the development. Odyssey Consulting Group, Stormwater
        Management Plan (Ref: K4277/P007/A) and Odyssey Consulting Group, Stormwater Detention and
        Bioretention Details (Ref: K4277/P010/A) included as Appendix F illustrates the size and location of
        the proposed SQID’s.

        MUSIC Version 6.1.0 has been used for modelling of the proposed treatment train.

5.4.1   Stormwater Quality Improvement Devices
        Site runoff will be directed across permeable pavements into two bio-retention basins located at the
        South and West of the site. The proposed treatment train for the development is shown in Figure 4.
