                 The developed site treatment train effectiveness is outlined in Table 2.

                 Table 2 - Treatment train effectiveness.

                 Based on the MUSIC modelling results in Table 2 above, the proposed treatment train achieves the
                 required pollutant load reduction objectives for all pollutants. The proposed proprietary treatment
                 measures are therefore considered adequate for the development. Further review and refinement of
                 the water quality treatment measures should be undertaken at the detailed design phase.

                 4. 3   Con st ruc t io n Ph a se

                 Management of stormwater runoff during construction and the implementation of an erosion & sediment
                 control program is necessary to avoid impacts to receiving waters from pollutants typically generated
                 during the construction phase. Typical pollutants are described in Table 3 below:
