Closure Standard
Scope
This standard is applicable to all Rio Tinto managed activities. Exploration projects, Order of Magnitude, Pre-feasibility, and Feasibility studies are required to adopt and comply with as many of the clauses in the Standard as are required to ensure withdrawal from a project or study in a manner that meets the intent of the Standard. Intent: The intent of this standard is to ensure that Rio Tinto managed activities are left in a condition which minimises adverse impacts on the human and natural environment, and that a legacy remains which makes a positive contribution to sustainable development. Rio Tinto’s assessment of performance in terms of closure and post closure planning and implementation is defined within the context of the Group sustainable development policy. Accordingly, this standard seeks to influence the design, development, operation and closure of all Rio Tinto managed operations so as to ensure the optimisation of post closure outcomes in terms of social, environmental and economic development needs and expectations. Specifically it is intended that this Standard will result in improved closure and post closure planning and implementation as indicated by: • • • • • • Improved scoping of closure in order to improve accuracy of Group closure cost estimates; Minimum costs of closure compatible with the objective of responsible social and environmental closure; Integration of closure planning into business plans resulting in reduced actual costs of closure over the long-term; Recognition and realization of positive legacies for local communities and lower exposure to future potential negative legacies; Increased host community ownership for post operational outcomes; and Enhanced reputation.

This will be accomplished through: • • • • Planning from project inception to ensure that closure is incorporated into project design; Commencement of provision for closure at project onset, followed by regular review and updating of the provision; Regularly reviewing and updating the scopes of closure strategy and plans; Ongoing implementation and stronger linkages between the outcomes of closure planning and core business plans, including mine plans and all other relevant planning documents; Integrated and accurate scoping of all aspects of the work required; and Development of strong and credible relationships with all stakeholders by consulting fully both internally and externally to increase levels of input and ownership.
