goldfields gas pipeline
The Goldfields Gas Pipeline (GGP) is a 1,378-kilometre transmission pipeline that extends from Yarraloola, in the Pilbara region of Western Australia, to Kalgoorlie, in the Goldfields-Esperance region. The 47-kilometre Newman lateral is also part of the GGP.
The 8-kilometre Wiluna Lateral, and laterals to Mt Keith (8-kilometre), Leinster (5-kilometre) and Kalgoorlie Power Station (8-kilometre) are owned and operated by APA and interconnect with the GGP. The GGP also interconnects with the Eastern Goldfields Pipeline System at Leonora. At its southern extremity, the GGP connects with the Kalgoorlie to Kambalda Pipeline.
A diagram of the GGP and interconnected pipelines can be found here, showing:
GGP and Newman Lateral — 88.157%.
Some of the assets composing the GGP are covered for the purposes of the access regulatory regime of the National Gas (Western Australia) Act 2009, and are a scheme pipeline. However, some of the assets forming part of the GGP are not covered by the access regime, and are considered to be a non-scheme pipeline.
The following assets form that part of the GGP that is a scheme pipeline:
The following assets are not covered for the purposes of the access regulatory regime of the National Gas (Western Australia) Act. They make up part of the GGP, which is a non-scheme pipeline:
The wholly owned APA laterals listed above are also non-scheme pipelines.
The Wiluna, Mt Keith, Leinster and Parkeston laterals have been granted exemptions from reporting requirements under Part 23 of the National Gas Rules.

Metering and Measurement
In Western Australia, transmission pipeline gas specifications are governed by state legislation – the Gas Supply (Gas Quality Specifications) Act 2009 (2009 Act) – and by regulations made under that Act. The 2009 Act provides for a Western Australian standard specification, which is set out in the regulations (with some variations for particular pipelines), and a reference specification for each pipeline. These specifications are necessary for the operation of the scheme of the legislation.
The GGP has been declared a PIA Pipeline for the purposes of the Western Australian Gas Supply (Gas Quality Specifications) Act 2009. The operator of the Goldfields Gas Pipeline, under the 2009 Act, is Southern Cross Pipelines Australia Pty Limited, a wholly owned subsidiary of APA Group.
The standard gas quality specification for the Goldfields Gas Pipeline is set out in clause 3 of Schedule 1 to the Western Australian Gas Supply (Gas Quality Specifications) Regulations 2010. The reference specifications for the Goldfields Gas Pipeline are set out in clause 3A of Schedule 2 to the Regulations.
The Wiluna, Mt Keith, Leinster and Parkeston laterals are all prescribed clause 3A pipelines under the West Australia Gas Supply (Gas Quality Specifications) Regulations 2010, to which the Goldfields Gas Pipeline reference specification applies.
APA will measure and/or monitor gas quality in accordance with relevant obligations under contract. Quality obligations are outlined in the SGTA (West) and the 2009 Act and underlying regulations, where applicable.
APA has minimum credit support requirements that are a pre-condition to gaining access to pipeline services. APA’s credit support requirements are set out here.
