The EPA is responsible for the control of stormwater pollution through the Environment Protection Act 1993 (EP Act). It provides the regulatory framework to protect the South Australian environment and is supported through a suite of subordinate legislation and regulatory tools including the Environment Protection (Water Quality) Policy 2015 (the Water Quality Policy).
The Water Quality Policy is second-level legislation and offers more specific protection for the state’s waters. It prohibits the pollution of the stormwater system and our natural waters. The policy has general obligations which every person, business and industry must comply with as well as specific obligations for particular activities.
