post-closure phase

The proposed dam monitoring and maintenance measures would need to be effectively implemented throughout all phases of the Project, including the longer-term post-closure phase.

However, concerns have previously been raised over the potential for superplasticisers to enhance the mobility of radionuclides during the post-closure phase of a geological disposal facility.

After closure, the minesite would need to be actively managed throughout an indefinitely long post-closure phase (likely lasting thousand of years) to ensure that the environment and public safety are protected.

The Panel is satisfied, taking into account the Proponent’s commitments and proposed mitigation and compensation measures, that the Project would not likely result in significant adverse environmental effects, providing that these commitments and measures are effectively implemented throughout all phases of the Project, including the post-closure phase.

The Panel concludes that, if the Project is approved, the Proponent’s water management plans for each phase of the Project would be generally acceptable, providing that the Proponent’s various water management commitments and proposed mitigation measures (including ongoing site management requirements) continue to be implemented throughout the longer term post-closure phase.
