Proposed Western Slopes Pipeline route map

On 31 January 2017, APA announced it had struck a Project Development Agreement with a subsidiary of Santos Limited to 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.

APA has now commenced a formal planning approval process for the Project with the submission of a Preliminary Environmental Assessment (PEA) in support of an application to the NSW Department of Planning and Environment to apply for approval of the Minister for Planning to carry out State Significant Infrastructure. It is expected that the Secretary’s Environmental Assessment Requirements (SEARs) to guide the preparation of a comprehensive Environmental Impact Statement will be issued by the Department in coming weeks. A copy of the application will soon be accessible on the Department’s ‘Major Project Assessments’ website.

A range of factors were taken into account in selecting the proposed pipeline route (see map above). These included environmental values, complexity of the terrain, the number of land parcels and landowners, and current land use considerations. Its design will be further refined during the planning phase by landholder 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.

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 million homes and 33,000 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.
