Framework for assessment procedures in EIA

The Environmental Impact Assessment (Part IV Divisions 1 and 2) Administrative Procedures 2021 (Administrative Procedures) form part of the EPA’s framework for Environmental Impact Assessment (EIA) procedures for proposals under Part IV of the EP Act (highlighted in the figure below). The scope of the Administrative Procedures are the procedures that the EPA administers, either as a decision-maker or a delegate of a decision-maker. These Administrative Procedures also relate to changes to proposals and conditions after an implementation statement (Ministerial Statement) is issued.


The Administrative Procedures set out the essential procedures in relation to the provisions of Part IV, Divisions 1 and 2 of the EP Act, grouped according to the following key stages:

  • Stage 1 Referral of a proposal to the EPA (s. 38)
  • Stage 2 EPA to decide whether or not to assess a referred proposal (s. 38A to s. 39B)
  • Stage 3 Assessment of proposals (s. 40 to s. 43A)
  • Stage 4 EPA report on the assessment of a proposal (s. 44)
  • Stage 5 Deciding if proposal may be implemented and implementation of proposals (s. 45 to s. 48).

The EPA’s Procedures Manual (Part IV Divisions 1 and 2) gives more detailed guidance on the processes and procedures for EIA of proposals under Part IV of the EP Act.

Environmental Protection Act amendments 2020 

Amendments to the EP Act were passed by the Western Australian Parliament in November 2020. Amendments relating to Part IV of the EP Act come into force on 22 October 2021. To implement the amendments, the EPA has revised its Environmental Impact Assessment (EIA) procedures suite, and the Statement of principles, factors, objectives and aims of EIA.

Instructions, templates and forms relating to these amendments are being updated and will be published shortly.

Additional to these amendments, the EPA have developed supplementary material to assist with the transition to the new procedures.
