As stated by Laurence (2006): ‘The excitement and fanfare that surrounds the opening of a new mine is never present when it finally closes.’ Although the timing may be uncertain, the closure of mines is ultimately inevitable. In 2014 a fire burned in Hazelwood Mine for 45 days, significantly impacting the local community. A government investigation, the Hazelwood Mine Fire Inquiry (HMFI), investigated the causes and contributing factors of the fire. Among its findings was a lack of preparedness both by government and industry for the closure of mining operations and the rehabilitation of the mines. Without coordinated planning and action, the region risked facing a ‘perfect storm’ of social, economic and environmental consequences. In Victoria, legislation defines the concept of a declared mine. A declared mine is defined as a mine that has geotechnical, hydrogeological, water quality or hydrological factors that may be deemed to pose significant risk of harm to the community, environment and infrastructure. As identified in HMFI 2016, the regulatory framework was not adequate to regulate the closure of declared mines in Victoria, there has been and continues to rapidly change to provide more focus on closure and rehabilitation. The catalyst for a shift of focus to mine rehabilitation in Victoria came with the Hazelwood mine fire in 2014 and the subsequent inquiry (Department of Jobs, Precincts and Regions), Hazelwood Mine Fire Inquiry 2016), which foreshadowed mine closure in the Latrobe Valley. These regulatory reforms come at a time when the declared mines in the Latrobe Valley come close to ceasing operations. Good practice in mine closure requires planning to begin before mining starts and to continue throughout the life of the mine. Significant regulatory change so late in the mine life cycle presents challenges for both operators and government. There are many examples of poor mine closure around the world. One particularly relevant case is that of the north-eastern counties of the United Kingdom where the whole coal industry was closed rapidly with little planning or care for the social or environmental impacts. Over 25 years later these counties are still feeling the effects (Sheldrick 2018). The closing of the Latrobe Valley mines has created many important questions that must be addressed to ensure successful outcomes, including: • What is the post-mining vision for the Latrobe Valley? • Where are we now, and how do we move towards that vision? • Are government, the mining industry, other industries and the community ready, and do they have the capacity, to begin the transition? Are they willing to collaborate and co-fund the transition process? • Is the current legislation fit-for-purpose and will it drive good outcomes? This paper will outline the emergence of a ‘perfect storm’ in the Latrobe Valley and offers potential solutions to help move towards the safe, stable and sustainable closure outcomes that all stakeholders seek. This paper does not address the community or First Nations’ engagement aspects required for mine closure planning and implementation in the Latrobe Valley.
