The Brockman Syncline project, 60 km from Tom Price, will involve the creation of new and above water table mining areas that will help sustain existing operations at Nammuldi, Silvergrass and Brockman 2 and 4.
As part of the proposal mine operator Hamersley Iron will extend two existing pits and build new pits above and below the water table at Brockman 4.
New AWT and BWT pits will also be built at Silvergrass and Brockman 2.
To facilitate development Hamersley Iron will also build waste dumps and install processing infrastructure.
Support buildings and access roads will also be constructed.
In accordance with the EPA's environmental impact statement procedure, the proposal is available for comment through a seven-day public comment period closing on August 22.
The EPA will factor in to its decision any comments made when it decides whether or not to assess the Brockman Syncline proposal and if so, at what level.
