Entities with mining operations will implement a comprehensive system for managing tailing's and waste rock, including:
- A commitment towards meeting the requirements of the Global Industry Standards for Tailing's Management.
- A governance system to oversee the identification and management of Tailing's, Tailing's Storage Facilities and waste risks, including the identification and appointment of adequately experienced roles, clarity on roles, responsibilities and organisational structures, adequate ongoing training for relevant personnel and a process for internal and external review and assurance throughout the entity’s life cycle.
- Allocating the necessary operational resources, including capital, human, financial, in the relevant business planning processes to implement and maintain the activities of the governance framework.
- A risk-based approach, including regular, rigorous risk assessment and transparent decision-making to choose the most appropriate site-specific approach to disposal, using the best available technology. Where risk assessment finds that conditions are inappropriate for marine or lake disposal of tailing's and waste rock or where there is insufficient data then this approach must not be utilised.
- Critical controls to identify, implement, communicate, and monitor actions for managing high risks, including assessing risks when internal or external factors change.
- Performance criteria established for the critical controls and their associated monitoring, reporting and verification activities.
- An engineer-of-record to provide technical direction for waste management and tailing's management.
- Independent review and evaluation of the controls to manage tailing's and waste by a competent, objective third party. This review should cover all aspects of the planning, design, construction, operation and maintenance of waste facilities and the outcomes and actions raised should be recorded, reviewed, addressed and communicated to executive management.
- Adopt a waste management policy, approved and endorsed by senior management, regarding management of waste materials and mine waste facilities in a manner that eliminates, if practicable, and otherwise minimises risks to human health, safety, the environment and communities.
- Design, construct, maintain and monitor tailing facilities and waste rock facilities to ensure structural stability, control discharge, and protect the surrounding environment and local communities and prevent catastrophic failures.
- Not use riverine tailing's disposal.
- Not use marine or lake tailing's or waste rock disposal for land-based mining facilities, unless:
- A thorough environmental and social analysis of alternatives, using scientifically valid data, was conducted that showed that marine or lake tailing's disposal creates fewer environmental and social impacts and risks than a land-based tailing facility.
- Scientific studies were conducted demonstrating that there are no significant adverse effects on coastal resources.
- There is long-term impact monitoring, including for cumulative impacts, and a provision made for a mitigation plan.
Carry out physical and geochemical characterisations and in-depth risk assessment of mining wastes so as to identify and manage potential impacts arising from acid rock drainage and metal leaching.
Protect the surrounding environment and local communities from potential impacts of acidification, metal leaching, loss of containment or contamination during the mine’s operation and post-closure.
For new mines or when significant changes are made to existing mines carry out screening to determine whether there are significant impacts on offsite human noise receptors.
For all mining facilities implement appropriate measures to establish baseline noise level and mitigating actions necessary to ensure noise does not exceed prescribed legal levels. Processes used must include engagement of relevant affected stakeholders in the mitigation strategies.
Mining facilities must establish strong and transparent governance mechanisms towards the use, disposal and management of natural resources (water, soil, and air) in its activities, including the establishment of clear accountabilities at site and board level and regular reporting of approach to natural resource stewardship, performance objectives (targets) against plans and risk mitigation strategies, and the identification and management of relevant risks.
Mining facilities must undertake measures to identify and record impacts on water, air quality and soil from mining facility operations on resource availability and quality and on surrounding communities.
All mining facilities must reduce significant impacts, including Greenhouse Gas emissions, water use and usage and increase resource efficiency on an annual basis. These measures shall include the following management system elements in relation to greenhouse gas emissions and energy use, waste water discharges and water use and air quality as a minimum:
- Publicly available policy.
- Assessment and management of emissions and resource use.
- Implementation of management and improvement plans and mitigation measures for significant emissions and resource use.
- Engagement with relevant stakeholders, including governments, local authorities and affected communities.
- Reporting progress publicly towards targets for improvement, material risks and opportunities, and at a minimum, report on the relevant GRI indicators for these material topics.
Entities should have a public net zero commitment to be achieved by 2050 or sooner; targets covering scope 1, 2 and 3 emissions as well as public reporting of progresses on scopes 1, 2 and 3 that aligns with the Task Force on Climate-related Financial Disclosures (TCFD) and has been externally verified.
Entities should monitor energy, water, and other identified significant natural resources used and establish associated efficiency initiatives, including working towards use of renewable energy in alignment with national targets or legislation, or water stewardship initiatives that promote responsible and sustainable water use and contribute to improved water security and sanitation.
Where entities are part of the mining sector policies, procedures and clear allocation of responsibilities in relation to water governance is required. Water use at facilities must be managed effectively using a water balance and taking cumulative impacts into account. Water performance must be publicly communicated and stakeholder collaboration utilised to achieve responsible and sustainable water use at a water catchment level.
