14 Risk management framework

(1) The owner of a declared dam must, as part of the dam safety management system for the dam, establish a risk management framework.

(2) A risk management framework must include the following components—

(a) a hazard identification process,

(b) a risk analysis process,

(c) a risk evaluation process,

(d) a risk treatment process.

(3) The hazard identification process must involve the identification of all foreseeable hazards adversely affecting the safety of the dam including, but not limited to, the following—

(a) flood events including the contents of the dam rising higher than the wall of the dam and the performance of the spillways,

(b) seismic events including the impact of the event on the performance of the dam or the stability of the reservoir rim,

(c) internal erosion including the effects this may have on piping through the dam, the foundation of the dam or structures abutting the dam,

(d) seepage of the contents of the dam through the wall of the dam,

(e) the stability of the dam through all possible conditions,

(f) sabotage or vandalism,

(g) fire,

(h) mechanical, electrical or automated system failure that may result in an uncontrolled release of the contents of the dam,

(i) human factors.

(4) The risk analysis process must employ an evidence based quantitative methodology that identifies and analyses the following—

(a) the potential failure modes of the various parts of a system in its operating context,

(b) the effects those potential failures may have on the system,

(c) how to avoid those potential failures,

(d) how to mitigate the effects of those potential failures on the system.
