Summary of response to inquiry recommendations ............................................ 59 ii Executive summary The Victorian Government received a market-led proposal from Transurban in March 2015 for the West Gate Tunnel Project. In December 2015, the government committed to the project, finding the proposal offered solutions to transport problems affecting Melbourne’s west and had substantial social and economic benefits. Since then, the project has been refined to a tender design, and a framework has been proposed to regulate its environmental effects. The project will deliver substantial benefits to metropolitan Melbourne and to the residents of Melbourne’s west in particular. The wider community will enjoy improved traffic flows on the M1 corridor, reduced reliance on the West Gate Bridge, expanded capacity on the West Gate Freeway, and improved connectivity between the expanding central city and Melbourne’s western suburbs. Many communities will benefit from less truck traffic on local roads, with the inner west also benefitting from improved pedestrian and cycling links and several new open spaces. Those near the West Gate Freeway will also receive greater noise protection from additional traffic noise reduction measures, while Port of Melbourne operations will be improved. In May 2017, I appointed an Inquiry and Advisory Committee (IAC) to consider the project’s environmental effects statement (EES), a draft planning scheme amendment and a works approval application. Planning Panels Victoria received 504 written submissions and the IAC held a public hearing from 14 August to 19 September 2017. During the hearings, the Government made the following announcements in response to submissions: Additional noise walls to be built along sections of the West Gate Freeway. A requirement for the operator to maintain reduced traffic noise levels throughout the term of the contract and for 20 years after the opening of the project. Truck bans applied when the project opens to Blackshaws Road and Hudsons Road. Incentives for the transport and logistics industry to use the project including setting discounted shuttle rates and capped maximum daily tolls for trucks making multiple trips through the tunnel, as well as night-time discounts. A requirement for the operator to include only one truck toll point on the West Gate Freeway, sited to the east of Millers Road, to reduce forecast truck use of Millers Road. A commitment to work with owners of properties that front Millers Road between the West Gate Freeway and Geelong Road on noise reduction measures, including double glazing, insulation, fencing and air conditioners. The IAC provided its report to me on 23 October 2017. It found considering the environmental effects overall, project approvals should be granted as the environmental effects could be managed to an acceptable level. Its report, submissions and the EES have informed the preparation of my assessment of the environmental effects of the project. My assessment is for the Minister for Roads and Road Safety and statutory decision-makers to inform any approval decisions on the project. I acknowledge the project will generate both positive and negative environmental effects. A sound regulatory framework and environmental control regime is needed to ensure any adverse local effects of the project are effectively mitigated. These effects can be managed and minimised through application of environmental performance requirements (EPRs, see Appendix A) that will set standards for project delivery. iii A key recommendation of the IAC was to lower the proposed Wurundjeri Way extension. During preparation of my assessment, I wrote to the proponent to request additional information on the feasibility and merit of this recommendation. The proponent has since advised the Wurundjeri Way extension can be lowered because the existing V/Line rail stabling facility
