A risk-based framework for completion criteria development – Dr Renee Young & Dr Marit Kragt

· 200 words, 2 minute read

Western Australia has recently adopted a new framework for developing risk-based, site specific completion criteria. Completion criteria are a necessary part of mine closure planning and fundamental to the successful transition of mined land to a future use. Once achieved, they demonstrate to the mining company, regulators and other stakeholders that financial assurances and liabilities can be removed. Because of this important function it is imperative that completion criteria are effectively formulated to capture end-state goals, are accepted by all stakeholders and agreed by regulators and the proponent, are achievable, and can demonstrate this achievement through transparent and appropriate monitoring and documentation.

In this webinar, two of the leading authors of the associated Completion Criteria report, Young and Kragt, present a high-level overview of the new process and some insight into its development through industry consultation. Six major components to the development of completion criteria are outlined: post-mining land use, aspects and closure objectives, references, attributes and risk-based prioritisation, criteria development, and monitoring; providing a guide that can help industry and regulators set SMART closure objectives. The first of its kind, the framework, is not only applicable to mine-sites but is transferable to other kinds of projects requiring completion criteria, nationally and internationally.

This short overview gives some key highlights from the new framework that will be presented in more depth at the Life of Mine Conference in 2021.


Dr Renee Young is an environmental scientist with extensive experience in both the academic and mining industry arenas. Currently in a joint position between the Western Australian Biodiversity Science Institute as the Program Director for Restoration and the manager of the ARC Centre for Mine Site Restoration, she facilitates integrated research programs that are aimed to develop proven, cost-effective, and scalable restoration solutions. Renee believes working collaboratively with industry, government and academic institutions across Western Australia is key to implement practical change that results in improved environmental outcomes.

Dr Marit Kragt is an agricultural and resource economist with particular expertise in interdisciplinary research that connects environmental science and economics. Marit works as an Associate Professor at the University of Western Australia’s School of Agriculture and Environment. She is an expert in non-market environmental valuation, and is currently conducting research on public preferences for, and values generated by, mine site rehabilitation in Australia.
