Proponent: INPEX Operations Australia Pty Ltd (INPEX)
Overview
INPEX Operations Australia Pty Ltd are proposing the construction, operation (including transport of carbon dioxide (CO2) and associated activities), decommissioning and abandonment of a CO2 transport pipeline and subsea power and fibre optic (SPFO) cable, including the construction of an onshore inlet station, located on the Middle Arm Peninsula within Darwin Harbour. The pipeline is approximately 90 km long, extending from the onshore inlet station to the boundary of the Northern Territory’s Coastal Waters.
The proposal is associated with other carbon capture and storage (CCS) proposals being:
- INPEX Operations Australia Pty Ltd - Ichthys LNG AGRUs Upgrades and CCS Preparedness Project
- INPEX Operations Australia Pty Ltd - Ichthys Carbon Capture and Storage Project.
While each proposal is being assessed separately under the Environmental Protection Act 2019, the NT EPA will consider direct, indirect and cumulative environmental impacts across all three proposals. As such, it is proposed to align the timing of the assessment process for the three proposals where possible.
Stakeholders will be able to participate in the assessment process by providing comments on either (i) each of the proposals individually, or (ii) via a single submission addressing all three proposals.
