When significant engineered structures, such as tailings storage facilities (TSFs), are approved by the department, they are generally subject to additional tenement conditions under the Mining Act 1978.
Tenement holders must submit geotechnical reports to the Department of Energy, Mines, Industry Regulation and Safety in accordance with these tenement conditions. These reports could be a once-off submission (such as a TSF construction report) or may be required to be submitted annually.
Submitting your report
Geotechnical reports are required to comply with a tenement condition, these should be lodged electronically via DEMIRS submissions. Always provide the tenement condition number/s that relate to the geotechnical report in the ‘Reference’ field.
Geotechnical reports submitted to comply with a tenement condition should not be attached to site Annual Environmental Report/s.
Geotechnical reports prepared for the approval of a new significant engineered structure (e.g. TSF design report) must be submitted with the associated Mining Proposal/Mine Closure Plan and should not be submitted through the DEMIRS Submissions system.
The lodged reports will be registered in our system and reviewed. Tenement holders will receive a response letter from the department when the report has been reviewed, or we may request for further information in writing during the assessment.
