Findings fromcan help governments, industry and the community provide better-informed regulatory, water management and planning decisions.
Assessment results flag where future efforts of regulators and proponents can be directed, and where further attention may not be necessary. This is achieved through the rule-out process, which directs focus onto areas where hydrological changes are predicted. This process has identified areas, and consequently water resources and water-dependent assets, that areto experience hydrological change or impact due to .
This assessment predicts theof exceeding levels of potential hydrological change at a regional scale and also considers cumulative changes from coal resource developments. It provides important to identify potential issues that may need to be addressed in local-scale environmental impact assessments of new coal resource developments. It should help project proponents to meet legislative requirements to describe the environmental values that coal resource development may affect, and to adopt strategies to avoid, mitigate or manage the predicted , including those that overlap with those arising from other future coal resource developments. These assessments did not investigate the social, financial or human health impacts of coal resource development, nor did they consider risks of fugitive gases and non-water-related impacts.
Bioregional assessments are not a substitute for careful assessment of proposed coal mine or CSG extraction projects under Australian or state environmental law. Such assessments may use finer-scale groundwater and surface water models and consider impacts on matters other than water resources as well as interactions with neighbouring developments.
The Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development (a federal government statutory authority established in 2012 under the Commonwealth’s Environment Protection and Biodiversity Conservation Act 1999) can use these assessment results to help formulate their advice on proponent’s proposals for coal resource development projects, and on addressingwith other developments.
The full suite of information, including information for individual assets, is provided at. Access to underpinning , including geographic data and modelling results, can assist decision makers at all levels to review the work undertaken to date; to explore the results using different thresholds; and to extend or update the assessment if new models or data become available. Additional guidance about how to apply the Programme’s methodology is also documented in 11 detailed scientific submethodologies (as listed in ‘ ’).
The Programme’s rigorous commitment to data access is consistent with the Australian Government’s principles of providing publicly accessible, transparent and responsibly managed public sector information.
