Water is used in a variety of ways in NSW, including for drinking, industrial activities and irrigation, and to preserve the health of the environment. The EPA needs to take all of these uses into consideration when it considers licensing an activity that may impact on a waterway.
Using environment protection licences to control water pollution
Schedule 1 of the Protection of the Environment Operations Act 1997 lists a broad range of activities that are regulated by environment protection licences (EPLs). These licences focus on protecting the environment (including human health) and address air, noise, waste and land contamination issues as well as regulating discharges to waters from premises.
The EPA regulates discharges to water using conditions it places on a facility’s EPL. These conditions can include
- restricting the amount of various pollutants that can be discharged
- requiring discharges to waters to be monitored and reported
- requiring that pollution control equipment operates properly and efficiently.
The EPA does not use licensing to regulate every potential pollutant that could be contained in a discharge or activity. This is because some pollutants are present at such low levels in a discharge that they are highly unlikely to pose a reasonable risk of harm to human health or the environment. Also some activities are are conducted in such a way that discharges to the environment are avoided – such as where an intensive agricultural activity uses an engineered runoff retention basin.
The EPA also uses a number of complementary regulatory tools to protect waterways from the impacts of pollution: these include investigations, research, monitoring and reporting programs, and public education.
