The EPA uses complementary approaches to protect the waterways of NSW from the impacts of pollution. These include planning processes, regulation, compliance programs, enforcement, market-based instruments and other economic incentives, investigations, monitoring and reporting programs, and public education.
The EPA regulates discharges to water using conditions it places on the environment protection licences that are issued under the POEO Act.
The wide range of potential water pollution sources means that the EPA shares responsibility for enforcement of the water pollution provisions under the POEO Act with local councils and many other agencies that also have powers of enforcement. Local government has a significant on-ground presence under the POEO Act. While the EPA regulates licensed premises and State or public authorities, councils regulate other activities through notice and enforcement powers.
