CSG Water Monitoring and Managment Plan - Full Plan (Stage 2)


Santos GLNG is a project that will convert coal seam gas (CSG) to liquefied natural gas (LNG) for export to global markets. In May 2010, the Queensland Coordinator-General approved the project under the State Development and Public Works Organisation Act 1971. In October 2010, the Minister of Sustainability, Environment, Water, Population and Communities (SEWPaC) (now the Department of the Environment) granted approval under the Environment Protection and Biodiversity Conservation Act 1999 (Commonwealth) (EPBC), with various conditions, in particular:

• Condition 49 requires the submission and approval of a Stage 1 Coal Seam Gas Water Monitoring and Management Plan within 6 months of project approval; and
• Condition 52 requires the submission and approval of a Stage 2 Coal Seam Gas Water Monitoring and Management Plan within 18 months of project approval.

Santos GLNG has prepared both Stage 1 and Stage 2 CWMMPs (CWMMP) within the specified timeframes to meet the requirements of these conditions. It demonstrates that when the cumulative impacts of the GLNG Project and other approved CSG to LNG proposals are taken into account, the potential for impacts to Matters of National Environmental Significance is low. With appropriate mitigation measures in place, the GLNG Project can be developed and operated in a sustainable manner.

What is the purpose of the CWMMP?

It describes the water that will be produced from coal seams, how it will be used, what the impacts are expected to be, and how the impacts will be monitored and managed.

When does the CWMMP apply?

The CWMMP covers the proposed management activities from the submission of the CWMMP in 2013 to the first LNG cargo scheduled for 2015.

What area is covered by the CWMMP?

The CWMMP covers three GLNG CSG fields that are proposed to be developed to varying degrees during this period: Roma, Fairview and Arcadia Valley.

What does the CWMMP demonstrate?

• Great Artesian Basin impacts are minimised
• Environmental impacts are minimised
• There are many water reuse options
• That salt management aligns with policy
• That there is an EPBC Springs early warning system
