TAILINGS storage facilities need to be reviewed at least once a year at a minimum, the Queensland Department of Natural Resources, Mines and Energy says.

Guidance note calls for better TSF management to avoid disasters such as the one that befell Samarco.

It said, in a guidance note on surface tailing storage facility management that mine management also had to audit to validate its TSF management systems, particularly that “sound risk-based controls are in place to ensure the ongoing integrity and safety of the TSF”.

The department said the review and audit should be carried out well before the storm season so an identified issues could be rectified.

“Management review should also cover human resources, including training or education to facilitate sound TSF operations,” it said.

According to the guidance note, less than adequate management of TSFs, often compounded by poor design, uncontrolled expansion or modification of the dam structure or extreme weather events had led to many tailings dam failures worldwide.
