Last updated:

Department of Water and Environmental Regulation (DWER) and Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) document hierarchy.

The Department of Water and Environmental Regulation (DWER) and Department of Energy, Mines, Industry Regulation and Safety (DEMIRS) release and maintain a range of documents on how agencies apply regulation in Western Australia.

DWER and DEMIRS have adopted a consistent document hierarchy model for mining environmental approvals documents, classifying them into four categories: legislation, policy, guidelines and procedures.

The hierarchy distinguishes between documents that specify:

  • mandatory requirements
  • those that provide high-level departmental policy positions
  • those that provide guidance or procedural information on technical and legal matters and the work of the agency.

Legislation

Legislation includes primary Acts and subsidiary legislation such as regulations, rules and legislative instruments.

State ºÚÁÏÕýÄÜÁ¿ agencies are required to:

  • consider and apply applicable laws in decision-making processes
  • act only within their powers, or the decisions they make may be considered invalid.

Stakeholders must comply with all applicable legislation. Those that do not may be penalised.

Policy outlines the key principles, objectives, outcomes and measures that establish an agency’s approach to a particular issue. Policies must be consistent with the administered legislation.

State ºÚÁÏÕýÄÜÁ¿ agencies develop and apply policies to interpret and apply applicable laws into decision-making processes. When an agency makes a decision that deviates from its policy, it must give its reasons in decision-making documents.
