The proposed development is integral to BHP Billiton's future expansion plans at its Western Australia Iron Ore operations, it said.
It is looking to develop a 240 mtpa iron ore export facility, to be known as the Outer Harbour, adjacent to its current Inner Harbour facility in Port Hedland. The project would involve the construction and operation of landside and marine infrastructure for the handling and export of iron ore.
Landside development includes rail connections and spur from the existing BHP Billiton Iron Ore Newman and Goldsworthy mainlines to proposed stockyards at Boodarie, stockyards and associated infrastructure, an infrastructure corridor from the stockyards to the proposed marine jetty and a transfer station and conveyors on Finucane Island.
Key marine structures include an abutment on Finucane Island, jetty and wharf and associated transfer stations, ore conveyors and shiploaders.
BHP said it anticipates that construction would be completed over four stages, with each stage taking between two and three years to complete.
The PER/Draft EIS is available for public comment for a period of eight weeks, giving interested stakeholders the opportunity to make their views known to government. The Commonwealth and Western Australia governments will then consider the PER/Draft EIS and the public submissions.
