The following is a summary of the changes introduced by the amendment, which address some inconsistencies and omissions in the October 2019 version of the regulation.

The new version of the regulation can be viewed at: https://legislation.nsw.gov.au/#/view/regulation/2019/506

The following is a summary of the changes introduced by the amendment, which address some inconsistencies and omissions in the October 2019 version of the regulation:

• The definition of ‘competent person’ has been amended, in clause 3 ‘definitions’, to clarify the knowledge and skills requirement for a person carrying out:
  * consequence category assessments (and reviews of consequence category assessments for high and extreme consequence dams)
  * dam safety reviews (and independent reviews of the safety reviews for high and extreme consequence dams)
  * reviews of dam designs.
  This change more clearly reflects the intent of the public submissions received during the exhibition of the regulation.
• In section 4, the criterion relating to whether a dam failure would endanger the life of a person has been re-instated as a type of dam that may be declared. This was included in the consultation draft of the regulation and was subsequently inadvertently omitted in the October 2019 version of the regulation.
• The references to the methodologies for the assessment of dam failure consequences and the calculation of societal and individual risk have been amended to refer to an updated version in the Gazette (Gazette No 137 of 8 November 2019). The updated methodologies include more detail and better reflect the intent of public submissions received during the exhibition of the regulation.
• Minor grammatical corrections.
