eastern goldfields pipeline system

The Eastern Goldfields Pipeline System (EGPS) comprises the Murrin Murrin Lateral and four transmission pipelines extending from the Murrin Murrin Lateral:

• The 85-kilometre Murrin Murrin Lateral (MML) is connected to the Goldfields Gas Pipeline and transports gas to the Murrin Murrin mine site approximately 69 kilometres east of Leonora, and to the Eastern Goldfields Pipeline.
• The 293-kilometre Eastern Goldfields Pipeline (EGP) connects the Murrin Murrin Lateral Pipeline to the Sunrise Dam, Tropicana and Granny Smith Gold Mines in the Eastern Goldfields Region of Western Australia.
• The 5.7-kilometre Gwalia Lateral delivers gas from the Murrin Murrin Lateral to the Gwalia mine site just south of Leonora.
• The 5-kilometre Mount Morgans Gas Pipeline delivers gas from the Eastern Goldfields Pipeline to the Mt Morgan Gold Mine, approximately 20 kilometres west of Laverton.
• The 198-kilometre Yamarna Gas Pipeline runs from the Eastern Goldfields Pipeline to the Gruyere Gold Mine Site in the eastern Yilgarn.

100%

All pipelines that make up the EGPS are non-scheme pipelines.

The Gwalia, Mount Morgans and Yamarna gas pipelines have current exemptions from reporting requirements under Part 23 of the National Gas Rules, as they are single shipper pipelines.

The following standard services are offered on the EGPS, subject to available capacity:

• Firm transport.
• Interruptible transport.
• In pipe trade.

A description of these services, including APA’s Standard Gas Transportation Agreement (SGTA) can be found on the gas transmission services page.

Relevant tariffs for standard services on the Murrin Murrin Lateral and Eastern Goldfields Pipeline can be found on the tariffs and terms page.

Non-standard services or alternative terms may be available by negotiation.

Notes on services

Firm services are available over varying terms as set out on the gas transmission services page.

Interruptible services are only available while the pipeline is fully contracted in respect of the corresponding firm service.

APA is progressively rolling out In pipe trade service capability on all key pipelines. APA will prioritise this service rollout in accordance with shipper demand.

APA is reporting financial information for its non-scheme pipelines — that is, pipelines that are not subject to full or light regulation, according to ERA’s Financial Reporting Guideline for non-Scheme Pipelines. The financial information for the six months to 30 June 2018 and the years ending 30 June 2019 - 2023 includes Pipeline Financial Statements based on Australian Accounting Standards, the weighted average price for services on each of these pipelines, and the number derived using the ERA recovered capital method (RCM).

Interested parties should read APA’s Basis of Preparation together with the completed financial information template that was developed by the ERA.

In addition, APA advises in relation to RCM:

1. The assumed initial capital structure is 40% equity and 60% debt. The level of equity will increase in circumstances where there is a shortfall in annual revenue.
2. The return on equity is a commercial return applicable in a workably competitive market. Historically, this return for an established pipeline was in the range of 9-11%, depending on factors such as risk, terms and counterparty.
3. The cost of debt is based on a 10-year rolling average of a market rate applicable for an entity whose business is solely the ownership and operatorship of the particular pipeline.
