All declared dam owners must produce a written risk report on all foreseeable risks to the dam:
- at least once every 5 years, and
- if you propose to make a major change to the dam, at the time the change is being designed that takes the proposed change into account, and
- if required to do so by Dams Safety NSW.
The risk report must use the risk management framework under clause 14 of the Dams Safety Regulation 2019, and set out
- the societal risk rating and the highest individual risk rating of the dam calculated using the Societal and Individual Risk Rating Methodology, and
- an explanation of any assumptions used when making that calculation.
