Information sheet - Notification of high risk mining activity: Construction of, or making substantial change to, a tailing storage facility (TSF)

Regulation 675UK of the Work Health and Safety (Mines) Regulations 2022 (WHS Mines Regulations) requires information about high risk mining activities at a mine to be notified to the regulator. Schedule 23 Item 11 of the WHS Mines Regulations outlines requirements for further information specific to tailings storage facilities.

Notification is required 45 days prior to commencing construction of, or making a substantial change to, a tailings storage facility at a surface mine.

Submission

All mine operators planning to commence construction of a new tailings storage facility (TSF) or make a substantial change to a facility are required to submit a HRA notification. This includes notification from underground mine operators where a TSF is a part of the surface operations on the site.

For an existing TSF for which subsequent lifts design details and construction methods have already been included in a previous HRA notification, no further HRA notification is required for the construction of the lifts included in that notification.

However, if the subsequent lift design details and construction methods have not been included in a previous HRA notification, a new HRA notification is required 45 days prior to commencing construction of, or making a substantial change to an existing TSF.

Under the Mining Act 1978, a mining proposal is required for submission and approval for mining activities that include tailings storage facilities. Design documents and risk assessments utilised in the approval process under the Mining Act 1978 may also be relevant for the high risk mining activity notification under the WHS Mines Regulations.

High risk mining activity notification document has been provided by DEMIRS for submission through the Safety Regulation System (SRS)
