Policies, Procedures and Requirements

Metering and Measurement

Metering and Measurement obligations are outlined in the SGTA (West) and for this pipeline are set out here.

Gas Specification

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 MWP and MMP are prescribed clause 1 pipelines under the West Australia Gas Supply (Gas Quality Specifications) Regulations 2010. The reference specifications for the MWP and MMP are set out in clause 1 of Schedule 2 to the Regulations.

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.

Credit support

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.
