After assessing The Environmental Impact Referral Document, DEWHA and the EPA determined that the proposed project should be formally assessed at the Environmental Impact Statement (EIS) and Environmental Review and Management Programme (ERMP) levels, respectively.

To support the assessment process, a number of detailed scientific surveys and studies were undertaken for a variety of marine, terrestrial and socio-economic and cultural factors identified during scoping. The information collected provided a baseline with which to inform the assessment of potential impacts to marine, terrestrial and socio-economic and cultural environments resulting from project development.

Chevron has implemented a trial of the risk-based approach for environmental impact assessment at the request of the EPA. The risk-based approach enables the potential impacts or hazards associated with project activities to be evaluated on the basis of potential risk to the environment.

Chevron Australia has prepared the Draft EIS/ERMP in accordance with the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and the Western Australian Environmental Protection Act 1986 (EP Act) as well as the project specific guidelines provided by the EPA and DEWHA and as set out in the Environmental Scoping Document (Chevron Australia 2009).
