Proponent: INPEX Operations Australia Pty Ltd (INPEX)
Overview
INPEX Operations Australia Pty Ltd are proposing the construction, commissioning, operation and decommissioning of a ~12 km carbon dioxide (CO2) export pipeline to tie in stations on Middle Arm, and hot commissioning and operation of the Ichthys LNG facility CO₂ compression and export system and upgraded acid gas removal units.
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 - Bonaparte Carbon Capture and Storage Project
While each proposal is being assessed separately under the Environment 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.
