A detailed traffic and transport assessment for the Project has been undertaken by GHD and is included in Volume 5, Appendix 23. Table 1 summarises the requirements from the Terms of Reference for the Preparation of an Environmental Impact Statement (ToR) for the Project and where they have been addressed in this chapter. TABLE 1 TERMS OF REFERENCE Section Terms of Reference Chapter Section 2.2 Project Components 2.2.1 Construction Phase The EIS should describe the preferred methods and processes during construction, including: traffic management requirements, including: Section 4.1.1 operating times and scheduling vehicle types, numbers and frequency the estimated volumes, tonnage, composition, origin, destination and proposed routes of traffic generated by the proposal hazardous or dangerous material that may be transported traffic flow management, including site access and signage. 4.7 Human Health and Safety 4.7.2 Assessment of Risks the risks can and will be managed effectively during the construction, Risk Assessment operation, and decommissioning of the Project, including safety risks (Volume 1, associated with: Chapter 8) and road users associated with increased traffic and use of the the Human Health existing road networks. and Safety Chapter (Volume 3, Chapter 3) 4.7.3 Mitigation A traffic impact assessment / traffic management plan (detailing access, Environmental vehicle types, volumes of existing vehicles and increased traffic and other Management Plan relevant matters, including a risk assessment) should be developed as part of (Volume 4, the EIS. Chapter 3) Volume 3 - Social, Economic and Cultural Assessment Chapter 4 - Traffic and Transport 4-1 Project Sea Dragon Stage 1 Legune Grow-out Facility Draft Environmental Impact Statement 1.2 REGULATORY APPROVALS, CONDITIONS AND AGREEMENTS The regulatory requirements relevant to traffic and transport are discussed below. 1.2.1 Control of Roads Act The NT Control of Roads Act controls activities undertaken on NT government roads and road reserves. Permits are required for conducting works and for the movement of heavy and oversized vehicles on NT roads. A permit is also required under the Act to conduct works within a road reserve including new access to private property, telecommunications and power installations. 1.2.2 Traffic Act The NT Traffic Act and regulations set out the road rules for the Northern Territory and the penalties for failing to abide by those rules. Road rules set out in the Act and associated regulations will be enforced on internal roads within Legune Station and transport routes between the other Project Sea Dragon facilities. 2 METHODS The following tasks were undertaken to complete this assessment: Review of existing transport conditions. Review of the proposed Project in terms of location, access, and its material and workforce transport needs during construction and operations. Assessment of impacts on the road network and identification of potential safety risks associated with increased traffic on the public road network. This includes an analysis of the amount of traffic that the Project is expected to generate and how it will use the road network. Impacts are described in terms of capacity and suitability of the transport network. Selection of mitigation measures to offset
