Table 2: Physical site information

Site aquifer formation The aquifer is underlain by silty clayey Sand of the Brighton Group likely overlying the Silurian formation at depths greater than 6 to 8 metres. Depth to groundwater is approximately 3.6 to 5.2 metres below ground level. Average depth to 3.6 to 5.2 metres bgl groundwater Groundwater segment Segment B was adopted with total dissolved solids (TDS) reported within the range of 1,250mg/L to 5,300mg/L. Groundwater flow North west direction Past use/site history The Site has been used for industrial and commercial purposes from 1945 until present. Surrounding land use North: Commercial/Industrial and residential properties East: Service station and residential properties South: Residential properties West: A former service station, then low density residential housing. High Density Residential / Mixed Use Redevelopment, including a supermarket Proposed future use and two storey basement car park.

Audit Summary Soil Assessment Results Following remediation of soils the remaining contaminants of concern beneath the Site were nickel and lead as listed in Table 10, Section 6.2. It must be noted that the reported results are below relevant health criteria for the proposed site development (i.e. NEPM HIL ‘D’). One soil analytical result was above the conservatively adopted NEPM HIL ‘A’ criteria for lead and another sample was above NEPM EIL (ecological) criteria for nickel, however values for these contaminants are well below criteria when considered in the context of statistically averaged concentrations across the Site (i.e. 95% UCL average concentrations). This Environmental Audit has been undertaken to assess the suitability of land for all potential land uses. The auditor considers that the site is conditionally suitable for all beneficial uses of land, as outlined below: • Parks & Reserves, • Agricultural, • Sensitive use – high density ( residential with minimal access to soil ), • Recreation/Open Space, • Commercial, and • Industrial. The site is considered unsuitable for the beneficial use of land Sensitive use – Other due to the potential for soil contamination to occur during existing site infrastructure demolition activities. It is noted that a management plan (i.e. a Construction Management Plan (CMP) incorporating a Project Environmental Management Plan (PEMP) as Section B) has been prepared and included in this audit report for the purposes of ensuring that the demolition is conducted appropriately. In addition a

S0019:JF :11178 EAR 188 Whitehorse Road, Balwyn iii February 2013

responsible party (i.e. Silverton Group) has provided written confirmation of the application and compliance with the CMP/PEMP by its contractor and sub-contractors during the demolition phase of the development project. Groundwater Assessment Results The results from groundwater analysis reported concentration exceedances above adopted criteria for beneficial uses for a range of inorganic parameters including metals/metalloids (i.e. copper, iron, nickel, selenium and zinc), chloride, sodium, TDS and nitrate as N. It is considered that the reported inorganic analyte concentration exceedances above adopted criteria are due to both anthropogenic (including the leaking upgradient (i.e. offsite) sewer infrastructure understood to have been repaired in late 2011) and natural (geological) sources. This was evidenced by representative upgradient wells GW1 and GW2 located near the southern boundary and bore GW7 located in the east of the Site as indicators of upgradient groundwater (see Figure 4, in Appendix B). Bores GW1 and GW2 were located near a former UST and oil sump. This infrastructure would not be the likely source of the reported contamination (i.e. copper, nickel and zinc) in this area of the site. Bore GW7 is also a representative upgradient bore and is located upgradient of the adjacent service station to the east of the site. This bore was not in an area known for historic contaminating activities and reported similar metals/metalloid contaminants to those reported on site. Based on a review of the data by the auditor as presented by Environmental Strategies Group (ESG), the auditor is of the opinion that the Site is likely to be a co-source site of nitrate contamination to groundwater from ageing sewerage pipes in the vicinity of the Site (including upgradient sources) and ageing onsite sewage infrastructure owned by Yarra Valley Water (i.e. inside the western boundary of the Site). Concentrations of nitrate as N, present in groundwater at the Site, exceeded beneficial use screening criteria for Potable water supply/Potable mineral water supply, Maintenance of Ecosystems, Industrial water use and Primary Contact Recreation . These beneficial uses are not expected to be realised at the Site. Nitrate pollution beneath the Site is not expected to impact down-gradient receptors (i.e. Glass Creek and the Glass Creek drainage channel reserve). It is noted that the nearest receiving waters are likely to be Glass Creek located approximately 2.6 km to the north west of the Site and the closest surface water receptor (i.e. the Glass Creek drainage channel reserve) is located approximately 875 metres also to the north west of the Site. Glass Creek flows into the after approximately 900 metres. Based on the above considerations it was determined that a formal Clean Up to the Extent Practicable (CUTEP) auditor’s opinion was required to be submitted to the EPA for their review and the Authority’s subsequent determination that CUTEP for the site had been achieved. Authority CUTEP Determination The auditor provided the Authority with a CUTEP Opinion report in November 2012 (Attached in Appendix J). Pursuant to Clause 19 of the State environment protection policy (Groundwaters of Victoria) , the Authority provided a determination by letter dated 18 December 2012 (refer to Appendix E) that: 1. Groundwater pollution at the site has been cleaned up to the extent practicable; and 2. The site is a Groundwater Quality Restricted Use Zone (GQRUZ).

S0019:JF :11178 EAR 188 Whitehorse Road, Balwyn iv February 2013

In addition, the Authority determined that a reference to the Construction Management Plan should be noted in the “Other related information” section of the Statement of Environmental Audit. The Authority also provided guidance for conditions (restricting groundwater use for existing and potential precluded extractive beneficial uses of groundwater); other related information to be included in the Statement of Environmental Audit; and, a requirement that the extent of GQRUZ is clearly delineated (refer to Figure 2, Appendix B and attached to the Statement of Environmental Audit). The Authority signed off that the following beneficial uses of groundwater have been precluded: Precluded Beneficial Use / Contaminant(s): • Agriculture, parks and gardens (Iron, selenium, chloride, sodium) • Stock watering (Selenium, chloride, TDS) • Primary contact recreation (Iron, nitrate as N, chloride) • Industrial water use (Iron, selenium, nitrate as N, chloride, sodium) A GQRUZ has been determined by the authority as the audited boundary of the site (GQRUZ plans attached, Figure 2, Appendix B). Auditor’s conclusion The Site is considered to be suitable for the proposed land use ( Sensitive Use - High Density (includes residential land use with minimal access to soil) and Commercial land use), in addition to potential land beneficial uses ( Parks & Reserves, Agricultural, Recreation/Open Space, and Industrial ). However, the site is considered unsuitable for the beneficial use of land Sensitive use – Other due to the potential for soil contamination to occur during existing site infrastructure demolition activities. It is noted that a management plan (i.e. a Construction Management Plan (CMP) incorporating a Project Environmental Management Plan (PEMP) as Section B) has been prepared and included in this audit report for the purposes of ensuring that the demolition is conducted appropriately. In addition a responsible party (i.e. Silverton Group) has provided written confirmation of the application and compliance with the CMP/PEMP by its contractor and sub-contractors during the demolition phase of the development project. A Statement of Environmental Audit is included in Appendix A which takes into account all relevant findings and conclusions and specifies the range of uses for which the site in its current form, is considered suitable. The suitability of the site for the proposed use (i.e. high density residential and commercial) is subject to conditions outlined in the Statement of Environmental Audit (Appendix A). The conditions are as follows: Condition A: Groundwater at the site is polluted. Groundwater must not be used for any extractive beneficial uses without prior testing, and the subsequent review of results by an Environmental Auditor (appointed under Part IXD of the Environmental Protection Act 1970 ) to confirm its suitability for that use Groundwater may be extracted for the purpose of environmental monitoring or remediation. Condition B: In accordance with the Project Environmental Management Plan (PEMP), prepared as part of the Construction Management Plan (CMP) for the site (Appendix H of the Environmental Audit Report), an assessment must be conducted by an appropriately qualified professional to verify in a report that site demolition works have not

S0019:JF :11178 EAR 188 Whitehorse Road, Balwyn v February 2013

affected the suitability of the site for the identified land beneficial uses. The report must be submitted to an Environmental Auditor for the purposes of providing written confirmation that the site is suitable for the identified land beneficial uses. Other Related Information Whilst not conditional to the issue of the Statement of Environmental Audit, the Environmental Auditor has provided additional information and recommendations with respect to the site condition and potential future usage of the Site. This information is provided in the Statement of Environmental Audit under the heading “Other related information” (Appendix A) and is summarised as follows: Other related information: 1. The Authority determined in a letter dated 18 December 2012 that groundwater has been cleaned up to the extent practicable (CUTEP) and that the Site is a Groundwater Quality Restricted Use Zone (GQRUZ). Refer to EPA letter in Appendix E of the Environmental Audit Report. The GQRUZ area is outlined on the plan attached to this Statement of Environmental Audit. 2. The auditor considers that groundwater beneath the Site is suitable for the following beneficial uses: Maintenance of Ecosystems; Potable Water Supply; and, Buildings and Structures . 3. Precluded beneficial uses of groundwater and the relevant contaminants are: Agriculture, Parks and Gardens (iron, selenium, chloride and sodium); Stock Watering (selenium, chloride and TDS); Industrial Water Use (iron, selenium, nitrate as N, chloride and sodium); and Primary Contact Recreation (iron, nitrate as N and chloride). 4. Asbestos containing material has been reported on the site as part of the main site building (eg. roofing material). As part of future development all site buildings are proposed to be removed from the site. The removal must be conducted in accordance with the Occupational Health & Safety Regulations 2007 (Part 4.3 Asbestos), including the use of an appropriately licensed contractor. Asbestos containing materials are proposed to be managed in accordance with the Project Environmental Management Plan (PEMP) for the site. See (7) below. 5. Some soil/fill/groundwater may contain odours below 1 metre depth at some locations on the site (eg. rotten fruit odour at GW4 or hydrocarbon odours in the vicinity of former UST1 tank pit). This material is not considered to represent a health or ecological risk, but may cause a noticeable odour if exposed during development of the site. Any materials emitting odours are to be assessed and managed in accordance with the Project Environmental Management Plan (PEMP) for the site. See (7) below. 6. Scattered pieces of concrete, brick and steel have been reported on the site. The material has been removed as far as practicable but minor occurrences may remain within the soil and be uncovered during excavation works. These materials are proposed to be assessed and managed in accordance with the Project Environmental Management Plan (PEMP) for the site. See (7) below. 7. A Construction Management Plan (CMP) has been prepared for the site which includes environmental management provisions primarily related to the infrastructure demolition/excavation phase of the proposed site redevelopment/construction project. It is a requirement (i.e. Condition No. 48) of the planning permit for the site (i.e. No PP09/00955 Ref. PA10/00007, 23 March 2011) that the CMP, as endorsed by the planning

S0019:JF :11178 EAR 188 Whitehorse Road, Balwyn vi February 2013

authority, is implemented for the demolition and construction phases of the proposed project. The environmental management provisions are contained in Section B of the CMP; entitled Project Environmental Management Plan (PEMP). The PEMP deals with site specific issues including the need to carefully manage the building demolition phase of the proposed development works to avoid site contamination by building materials such as fragments of asbestos containing materials (ACM) and leaded paint flakes. The PEMP also provides measures for dealing with any residual hydrocarbon contamination or odours that may be encountered during the proposed demolition/construction works. The CMP is attached as Appendix H of the Environmental Audit Report. Silverton Group Pty Ltd has provided a written statement dated 31 January 2013 (attached in Appendix E of the Environmental Audit Report) confirming that they will be responsible for the implementation of the PEMP. 8. Section 53ZE of the Environment Protection Act 1970 requires the owner/occupier of the site to provide a copy of the Statement to any person who becomes or proposes to become an occupier of the site. 9. In accordance with clause 19(3) of SEPP (Groundwaters of Victoria 1997), the Authority may require periodic reassessment of the practicability of groundwater clean up. 10. Groundwater monitoring bores (i.e. GW1, GW2, GW3, GW4, GW5, GW6 and GW7) must be decommissioned in accordance with the requirements of “Minimum Construction Requirements for Water Bores in ”, published by the Land and Water Biodiversity Committee (version relevant at the time of decommissioning). 11. Any material excavated from the site and disposed of offsite must be classified and managed in accordance with relevant statutory regulations and EPA guidelines (including EPA Publication IWRG621, Soil Hazard Categorisation and Management, dated June 2009). 12. Any fill or soil imported to the site must be chemically tested soil or fill that classified as “fill material” in accordance with relevant EPA guidelines. 13. Not all land uses for which the land is considered suitable by this audit may be allowed under the existing zoning of the local Council.
