* This includes access tracks through pastoral properties, equipment and personnel to the CROW and worksites.
* Construction of the Shenandoah Facility and construction of the Sturt Plateau Facility)
* Development and utilisation of ancillary surface infrastructure, including:
* Establishment of a temporary construction camp for up to 150 people, including diesel storage, wash-down facilities, wastewater treatment, and waste management
* Development of additional work areas, such as construction laydown areas
* Sourcing gravel from borrow pits within the Project Area, including a proposed 50 m by 50 m pit at the Sturt Plateau Facility laydown area; additional material may come from the temporary construction camp area, with final locations determined after geotechnical assessment, and
* Sourcing of water for dust suppression, trench compaction, hydrostatic testing, and potable use from existing Tamboran bores and new APA SPP Pty Ltd bores near the Shenandoah Facility. At least two new bores are planned for the temporary campsite.
* Construction and installation of pipeline:
* Two potential construction footprints have been identified, but only one will be selected based on the construction direction.
* The pipeline extends from kilometre point (KP) 0) at the Shenandoah Facility (NT Portion 7026) to the KP 37 at the Sturt Plateau Facility (NT Portion 1077). Construction will either proceed from KP 0 to KP 37 or in reverse, depending on weather and site conditions. If construction starts at KP 0, the working side of the ROW will be north of the alignment; if starting at KP 37, it will be to the south.
* The construction sequence will involve clearing of vegetation from the CROW and stripping of topsoil to conserve for use in rehabilitation, delivering pipe lengths to the ROW, bending and welding the pipe lengths to follow landforms, non-destructive testing, coating welds, excavating the trench, lowering and welding the pipeline, and backfilling with excavated material. Horizontal boring at KP 27 will cross the Stuart Highway. Additional activities include hydrostatic testing, installing markers and gates, and rehabilitation of the CROW .
* The 37 km pipeline, with a nominal diameter of up to 300 mm and operational capacity of up to 50 terajoules per day (TJ/day), will be constructed in accordance with Australian Standard (AS) 2885.
* The pipeline will be buried at a minimum depth of 750 millimetres (mm), with 3,000 mm cover, from the road crown, at the sealed road crossing (Stuart Highway) and 1,200 mm at unsealed roads, drainage lines, and floodplains.
Operation phase
The estimated duration of pipeline operation is 40 years. The operational footprint for the Proposed Action, defined as, the area of land required to operate and maintain the Project is approximately 112 ha.
The activities associated with the operation phase of the SPP includes implementation of a routin
