Existing Environment
The existing marine environment close to the Crux project has been carefully studied in the context of two areas. The first, the project area considers the in-field development area where the Crux platform and other infrastructure will be established, including the pipeline corridor that will connect Crux to the Prelude FLNG facility. The second considers the wider area of influence which could be affected in the unlikely case of an emergency.
The Commonwealth Government’s Environment Protection and Biodiversity Conservation Act (EPBC Act) provides for the national protection of the environment, particularly regarding matters of national environmental significance. The physical and biological features of the project area and area of influence have been evaluated to understand the potential impacts of the development and propose effective risk management and mitigation strategies. Existing environmental features are referred to as “receptors” and are categorised according to the table:
