Rio Tinto, along with the other members of the International Council on Mining & Metals (ICMM), have committed to achieving compliance with the Global Industry Standard on Tailings Management (GISTM), which was released in 2020 by the independent Global Tailings Review following the Brumadinho tailings disaster.
Risk assessment and management is a fundamental requirement of the GISTM, including risk profile establishment and implementation of risk-informed decision making for the management and potential upgrades of existing TSFs.
In 2021, Rio Tinto Iron Ore (RTIO) engaged HATS to complete a portfolio risk assessment (PRA) for their tailings and water storage facilities in the Pilbara region of Western Australia as part RTIO’s progress towards GISTM compliance.
The risk assessment was completed using HATS’ Risk Assessment and Management Platform (RAMP). Risk profiles were developed for 26 embankments across 15 facilities and eight operations between October and December 2021.
The results of the PRA further informed RTIO’s already well-established understanding of their facility risks and allowed direct comparison across the portfolio. The identified potential areas for improvement were directly linked to the effectiveness of critical controls, following the Critical Control Management (CCM) philosophy of ICMM. The outcomes of the PRA informed the prioritisation of risk-reduction measures and supported RTIO’s implementation of risk-informed decision making.
HATS was engaged by Rio Tinto Iron Ore (RTIO) to undertake an assessment of compliance with the requirements of GISTM, as an extension of a recently completed portfolio risk assessment (PRA) for their tailings and water storage facilities in the Pilbara region of Western Australia.
The assessment was completed in February 2022 using the Compliance Application within HATS’ Risk Assessment and Management Platform (RAMP). The assessment was completed efficiently by utilising many of the inputs already established during the PRA, enabled by RAMP’s integral link between risk profile and industry compliance.
The link between facility risk and GISTM compliance presented by RAMP allowed RTIO to efficiently identify actions which both minimised the risk posed by a facility while improving compliance with GISTM.
