APA Group has contracted with a subsidiary of Santos Limited to commence the development of a new circa 450 kilometre pipeline (the Western Slopes Pipeline (‘WSP’)) from Santos' proposed Narrabri Gas Project to connect to the existing APA owned East Coast Grid through the Moomba Sydney Pipeline at the Bundure mainline valve station, approximately 100km west of Condobolin. APA will build and own the pipeline, at a total construction cost of around $500 million, subject to various approvals including a Final Investment Decision by Santos of the Narrabri Gas Project and execution of an agreed form gas transportation agreement. APA will soon commence a comprehensive regulatory approval process with the submission of a Preliminary Environmental Assessment (PEA) to the NSW Department of Planning and Environment. The PEA will include details of a proposed pipeline corridor, located west of the existing Central West Pipeline which preliminary studies identified as the most suitable for construction. A range of factors were taken into account in selecting the proposed pipeline corridor including environmentally sensitive areas, the complexity of terrain, the number of land parcels and landowners along the proposed pipeline route, and current and future land use considerations. Further steps in the design and construction of the WSP are subject to a series of staged regulatory approval requirements that will be informed by extensive landholder and community consultation, detailed environmental studies and public comment.
