“The plan details the rehabilitation processes and outcomes required for ERA to meet our environmental obligations,” he said. “The plan, which will be subject to ongoing review and refinement, is based on extensive scientific research and world-class engineering design.”It incorporates stakeholder feedback received through a rigorous consultation process following release of a draft plan in December 2016. Key stakeholders include the Gundjeihmi Aboriginal Corporation, as representatives of the Mirarr Traditional Owners, Northern Land Council and Northern Territory and Commonwealth government agencies. It has also been developed in accordance with Rio Tinto’s internal requirements for mine closure; in the absence of relevant Northern Territory closure plan guidelines (which are under development), it refers to Western Australia’s Guidelines for Preparing Mine Closure Plans (2015) to ensure that an appropriate planning process is in place to decommission, rehabilitate and close the site. The objective is to close and rehabilitate the entire Ranger project area, to form one final landform across the site that will blend with the surrounding landscape. The total area of disturbance is approximately 950 hectares. The closure activities will include:
- Pit 1 tailings impoundment and backfill;
- Water treatment;
- Pit 3 tailings and brine impoundment and backfill;
- Tailings dam deconstruction;
- Contaminated sites remediation;
- Processing plant and other infrastructure deconstruction; and
- Final landform contouring and revegetation
