The environmental impact assessment process The South Road The Project Impact Report, prepared by an integrated team of staff from Superway Project is Aurecon, QED, GHD and GTP, evaluates the effects of the proposed project. Decisions about the project will then be made taking these effects into being assessed using account and will include appropriate mitigation and management measures. DTEI’s environmental The report also details the project and enables the community to provide impact assessment feedback on aspects of the project. process, which is similar Environmental, social and economic investigations by technical specialists to processes for Major have identified and described the effects of the project on the existing Projects under the environment and community, and outlined proposed management measures. Development Act 1993. The Project Impact Report is being publicly displayed for a period of 20 business days, during which time, submissions are invited commenting on any issues associated with the project. Formal comment is also requested from government agencies during this public display period. The report is available on compact disc and on the project website: www.infrastructure.sa.gov.au Hard copies are on display at a number of locations throughout the study area, see website for display locations. This Executive Summary of the report is also available. A Supplement document will address the submissions received from the public and government agencies. It will also outline the findings of further investigations since the Project Impact Report was prepared. The Supplement, together with the Project Impact Report, will be considered before the proposed project is finalised for approval by the Australian and South Australian Governments (Figure 2). The Project Impact Report and this Executive Summary have been written for interested groups, individuals, businesses, government agencies and local government to help explain the project and its effects.
