                    <0.001% asbestos in soil on a weight for weight basis (w/w) for free fibre related materials including Fibrous Asbestos (FA) and
                    Asbestos Fines (AF). The definition of AF includes small fragments of cement sheeting with a diameter less than 7mm.

                    For ACM (bonded asbestos with a diameter greater than 7mm) <0.01 % w/w asbestos for low density residential use, <0.02% for
                    public open space and <0.04% for residential with minimal opportunities for soil access such as apartments and high-rise.

                    In addition to the above, no reportable asbestos present within the top 100mm of soil or within any soil proposed to be disturbed by
                    redevelopment activities.

                                                                                 Aesthetics

                    No foreign material (scrap/waste) such as plastic, rubber, metals, timber, steel, brick/concrete (>100mm) and no discoloured or
                    malodourous soil or water.

                    ^ NEMP interim soil – ecological indirect exposure for residential.
                    Where no criteria exist or are defined, the screening level adopted is the laboratory level of reporting. If
                    detectable concentrations are recorded, then further assessment may be required to be completed.
                    Statistical analysis of assessment or validation samples may be undertaken where appropriate. This may
                    include a 95% Upper Confidence Limit (UCL) analysis for contaminants less than 250% of the criteria, for
                    a discrete soil/fill population.
                    The laboratory summary tables include the above criteria sets, as well as HIL D for commercial or
                    industrial landuse.


        7.2.        SURFACE AND GROUNDWATER VALUES AND OBJECTIVES
                    The Environmental Protection (Water and Wetland Biodiversity) Policy 2019 (EPP) is progressively
                    determining Environmental Values (Evs) and water quality objectives for water basins and wetlands in
                    Qld, to facilitate environmental protection while allowing for development that is ecologically sustainable.
                    Where a basin framework under the EPP is not currently available, the previous framework under the
                    Environmental Protection (Water) Policy 2009 is applicable, as follows:

                    •    Environmental Protection (Water) Policy 2009 Mary River environmental values and water quality
                         objectives Basin No. 138, including all tributaries of the Mary River, July 2010 (EPP Mary River)


                    As discussed in Section 3.1 any intermittent surface flows from the site would collect in unnamed
                    channels and then into Six Mile Creek Left Branch that is a tributary of the main Six Mile Creek, a lowland
                    freshwater system. The intersection of these waterways is downstream of Lake Macdonald that is located
                    nearby on Six Mile Creek and used for potable water supply.
                    Six Mile Creek discharges some 35km to the north-west of the site into the Mary River, just south of
                    Gympie. The EPP Mary River Evs for Six Mile Creek and groundwater are presented in Figure 16 below.
