In November 2006, the then Commonwealth Minister for the Environment and Heritage determined that the Project was a “controlled action” requiring approval under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), with the controlling provisions being the world heritage values of Fraser Island, Ramsar wetlands, listed threatened species and communities and listed migratory species. Under the terms of the bilateral agreement between the Queensland Government and the Australian Government, the SDPWO Act EIS process is accredited for the EPBC Act, and accordingly my assessment has considered the relevant impacts of the Project on matters of national environmental significance under the EPBC Act in addition to State requirements. The Project is the design, construction, operation and maintenance of the Traveston Crossing Dam Stage 1 on the Mary River approximately 27 km upstream of Gympie. The Project includes access roads and the relocation of sections of existing roads and infrastructure. The Project would inundate approximately 36.5 km upstream along the Mary River from the embankment at 207.6 km AMTD. The dam would have a full supply level (FSL) of 71.0 m Australian Height Datum (AHD) and an inundation area of 3,039 ha, with a storage capacity of approximately 152,429 ML with a proposed yield of 70,000 ML/annum. The preliminary design consists of a Roller Compacted Concrete Dam (RCC dam) approximately 760 m wide and 52 m tall, with a gated spillway and includes fishway and passage for other aquatic fauna including turtles. Draft terms of reference for the EIS were issued for public comment from 9 December to 19 February
