Bengalla Mining Company Pty Limited - Rio Tinto Coal Australia

Rehabilitation & Landscape
Management Plan
3.3 Medium & Long-term Management Measures
The rehabilitation measures described in Section 3.2 will continue to be implemented
over the life of mining at Bengalla. This will ensure the rehabilitation activities result in a
final landform which is undulating and free-draining (Figure 1) and has post-mining land
capability (Figure 2) as determined in consultation with relevant stakeholders.
In particular, the completion criteria and performance monitoring discussed further in
Section 3.4 provide an evaluation mechanism of the rehabilitation measures being
implemented. The rehabilitation measures are subject to continuous review and
improvement, reflecting the results of performance monitoring and progress towards
rehabilitation targets.
3.4 Completion Criteria
Initial completion criteria for the short-term (annual), medium-term (< 5 yrs) and longterm
(life of mine) have been developed to achieve the site rehabilitation objectives and
are shown in Table 4. Rehabilitation that achieves the completion criteria will be
considered to be sustainable without ongoing management and therefore suitable for
mining lease relinquishment.
The completion criteria include success indicators and monitoring requirements to
monitor the successful establishment of rehabilitation and trigger remedial action, where
necessary. This will ensure that rehabilitation achieves the completion criteria in a
suitable timeframe, consistent with the mine closure plan.
