Western Slopes Pipeline Alignment

On 31 January 2017, APA announced it had entered into a Project Development Agreement with a subsidiary of Santos Limited to commence work with regulators and the community towards the development of a new 450km (approximate) pipeline - the Western Slopes Pipeline. The purpose of the Project is to connect a new source of gas from Santos' proposed Narrabri Gas Project to the NSW gas transmission network, via the Moomba Sydney Pipeline.

We commenced a formal planning approval process for the Project in February with the submission of a Preliminary Environmental Assessment (PEA) in support of an application to the NSW Department of Planning and Environment to carry out State Significant Infrastructure. The Secretary's Environmental Assessment Requirements (SEARs) to guide the preparation of a comprehensive Environmental Impact Statement are now available. Copies of both documents can be accessed at http://majorprojects.planning.nsw.gov.au/index.pl?action=view_job&job_id=8272 .

A range of factors were taken into account in selecting the preliminary pipeline alignment (see map above). These included environmental values, complexity of terrain, the number of land parcels and landowners, and current land use considerations. Its design will be further refined during the planning phase through landowner and community consultation, detailed environmental studies and consideration of public comment. The Project is ultimately subject to various statutory and other approvals or arrangements being obtained, including Ministerial approval.

Santos estimates the proposed Narrabri Gas Project has the potential to supply up to 50 per cent of the natural gas needs of more than 1.1 million homes and 30,000 business and industrial customers in NSW. It further estimates about 300,000 jobs rely on a safe and secure supply of natural gas. Accordingly, the Western Slopes Pipeline has the potential to significantly increase the supply of natural gas to the NSW market and play a key role in helping the State achieve greater energy security and economic sustainability.
