Edithvale and Bonbeach Level Crossing removal project Report of Dr Anthony Smith 1 Introduction I have been engaged on behalf of the Level Crossing Removal Authority to peer review the EES Technical Report A Groundwater Impact Assessment (LXRA-LX31-00-GE-EES-0001, Revision: 1) contained in the Environment Effects Statement (EES) prepared for the Edithvale and Bonbeach Level Crossing Removal Projects (Projects). 2 Qualifications and experience Appendix A contains a statement setting out my qualifications and experience, and the other matters raised by Planning Panels Victoria 'Guide to Expert Evidence'. A copy of my curriculum vitae is provided in Appendix B. 3 Peer Review I have read the 248 submissions to the EES and identified those containing issues that are relevant to my area of expertise. No change is required to my Peer Review Assessment because of my review of the issues raised in the public submissions. It is my opinion that the groundwater components of the EES for the Edithvale and Bonbeach Level Crossing Removal Projects, as reviewed Peer Review Assessment, are fit for purpose and do not contain significant technical flaws or errors. The approaches, methods and findings of the groundwater assessment components of the EES are considered justified and adequately supported through analysis of available existing information, hydrogeological conceptualisation of groundwater conditions and interaction with surface water, and predictive simulations of potential future conditions conducted using industry-standard modelling codes and methods. The claimed model confidence level classification of Class 2 to 3 for the groundwater flow modelling conducted for the EES is considered justified under the criteria of the Australian Groundwater Modelling Guidelines (Barnett et al. 2012) including the criteria for data availability, calibration quality, and magnitude of potential effects relative to historical variation in groundwater conditions. Reference Barnett et al, 2012, Australian groundwater modelling guidelines, Waterlines report, National Water Commission, Canberra. Declaration I have made all the inquiries that I believe are desirable and appropriate and that no matters of significance which I regard as relevant have to my knowledge been withheld from the Inquiry and Advisory Committee.

Appendix C Independent Peer Reviewer Terms of Reference L\326385819.1 8
Edithvale and Bonbeach Level Crossing Removal Environment Effects Statement Independent Peer Reviewer Terms of Reference Section 1: Introduction The Victorian Government is removing 50 of Melbourne s most dangerous and congested level crossings, inclusive of the level crossings at Edithvale and Bonbeach. The Edithvale and Bonbeach level crossing removal projects were referred to the Victorian Minister for Planning on 9 March 2017. On 5 April 2017, the Minister issued a decision determining that an Environment Effects Statement (EES) is required for the projects due to the potential for a range of significant environmental effects. The project s proponent, Level Crossing Removal Authority (LXRA), has engaged the AECOM-GHD Joint Venture (JV) to prepare the EES and undertake the supporting technical studies. One of the key technical studies for this EES is the groundwater assessment. Tony Smith of CDM Smith (Perth) has been engaged by the JV to undertake an Independent Peer Review of this study. These terms of reference have been developed to guide the peer review process and can be amended with agreement of the peer reviewer and the JV. Section 2: Purpose and role The role of the Peer Reviewer is to provide an independent peer review of the groundwater technical impact assessment produced by the JV for the Edithvale and Bonbeach level crossing removal EES. In particular the review should: assess the design of and adequacy of the groundwater technical assessment to identify and assess the potential environmental effects of the projects, and address the scoping requirements (prepared by the Department of Land, Water Environment and Planning (DELWP) for the EES. The peer review should consider: relevant legislation, guidelines and policy consistency of methodology with good practice standards of methodology and analysis, including the availability of relevant data sets and research the approach to field work, data collection and analysis the assumptions and integrity of the data used to develop the regional groundwater modelling provide a robust basis for understanding the potential changes to groundwater conditions confirmation that the conclusions of the groundwater assessment and any proposed mitigation are sound and reasonable and practicable. Section 3: Independent Peer Review Protocols
The Independent Peer Reviewer will be required to: Conduct all communication through the JV Planning and Environment (P&E) contacts listed in Section 5 below. Ensure the integrity, independence and professionalism of the peer review process, and immediately advise the JV of any potential, perceived or real risk to that independence Issue letter reports for interim deliverables such as scope and methodology review(s) Issue a formal report summarising the review of the groundwater modelling and technical impact assessment report addressing the points in Section 2 above Agree in advance on delivery timeframes for reviews, and provide at least three days notice if agreed timeframes cannot be met. Section 4: Program The groundwater technical assessment program will be provided separately to the peer reviewer and is subject to change. However there are a number of key dates to be aware of: the risk assessment workshop will be held 22 August 2017 the Technical Reference Group meeting for review of the groundwater report will be held 26 September 2017 (with the draft report submitted one week in advance of the meeting) EES submission is proposed for mid November 2017 public exhibition of the EES is proposed for late January 2018. Section 5: Project team The independent peer reviewer for this project is: Tony Smith from CDM Smith (Perth). The JV P&E contacts for the peer reviewer within the JV are: Rachel Harding Natalie Jiricek Aime Bigornia. <PW_ENV_DocCode> Revision <PW_ENV_DocRev> <PW_ENV_Subject> Page 2
