Licences and works approvals for prescribed premises

The Department of Water and Environmental Regulation is responsible for environmental regulation in Western Australia.
Last updated:

We regulate certain premises through a works approval and licensing process to prevent, control, abate and mitigate pollution or environmental harm, under Part V of the Environmental Protection Act 1986 (EP Act).

These premises with potential to cause pollution or environmental harm to the environment, water resources, public health and/ or amenity are known as ‘prescribed premises’. Prescribed premises categories are outlined in Schedule 1 of the Environmental Protection Regulations 1987.

The EP Act requires a works approval to be obtained before constructing a prescribed premises and makes it an offence to cause an emission or discharge unless a licence or registration is held for the prescribed premises.

General information on our regulatory role and the timeframes for assessments and determinations is outlined in our regulatory services fact sheet.
