Submission #1996 - Marble Bar Road (M030) Coongan Gorge Realignment Title of Proposal - Marble Bar Road (M030) Coongan Gorge Realignment Section 1 - Summary of your proposed action Provide a summary of your proposed action, including any consultations undertaken. 1.1 Project Industry Type Transport - Land 1.2 Provide a detailed description of the proposed action, including all proposed activities. Main Roads Western Australia (Main Roads) is proposing to upgrade a section of Marble Bar Road at Coongan Gorge from 318.4 to 323.5 Straight Line Kilometre (SLK). The purpose of the proposed works is to improve safety on this section of Marble Bar Road, connecting Port Hedland to Marble Bar. The proposed project works will include: - Realignment and reconstruction of approximately 5 km of Marble Bar Road between 318.4-323.5 SLK. Road formation width will vary significantly due to varying batter slope distances (at the narrowest road formation will be 10 metres (m) wide, and in isolated areas road formation will be up to 170 m wide) - Associated works including significant road batter construction, minor floodways, culverts and off road drainage - Development and use of a side track to divert traffic during stages of construction - Extraction of basecourse material from M030 material pit if excess cut material is not suitable for road base. M030 material pit is located on the Marble Bar road at 356 SLK, The Project is being referred to the Department of the Environment and Energy (DotEE) as it may result in the loss of known and potential habitat for the following Matters of National Environmental Significance (MNES) listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) including: • Northern Quoll (Dasyurus hallucatus) – Endangered under the EPBC Act • Pilbara Olive Python (Liasis olivaceus barroni) - Vulnerable under the EPBC Act The project area (the maximum area of disturbance) is 43.64 ha, which includes 33.64 ha for the Coongan Gorge realignment and potentially a further 10 ha area for the M030 material pit, including previously cleared areas and the clearing area for the proposed road upgrades. The Project is to be developed in an area that is 166.45 hectares (ha) in size and includes: • Coongan Gorge realignment footprint covering 33.64 ha. This includes 31.55 ha of native vegetation and fauna habitat, 2.09 ha of highly disturbed areas (excluding the 5.63 ha of the existing Marble Bar Road and associated shoulder). Approximately 4.45 ha of the 33.64 ha of native vegetation clearing is temporary clearing associated with the construction of a side track. • M030 proposed material pit footprint covering 132.81 ha. Main Roads intend to limit Submission #1996 - Marble Bar Road (M030) Coongan Gorge Realignment disturbance to an isolated 10 ha within the material pit footprint, although at this stage the location of this disturbance is not defined. The material pit includes 113.72 ha of native vegetation and fauna habitat, and 19.08 ha of highly disturbed areas. Main Roads intend to use the material pit for construction, only if the excess cut material from the realigned section of Marble Bar road cannot be made into suitable basecourse quality material. It should be noted that the project is only in the concept design phase. Minor changes in the design may occur in the detailed design process. The clearing footprint for the road construction project has been buffered by an additional 10 m to the planned clearing extent which will account for any variations between the concept design and final design that is constructed. 1.3 What is the extent and location of your proposed action?
