Taronga Zoo holds an Environment Protection Licence (EPL #: 1677) to discharge water into Sydney Harbour. This licence is issued under the Protection of the Environment Operations Act 1997 (POEO Act).

In accordance with section 66(6) of the Act Taronga is required to publish pollution monitoring results gathered as a result of Taronga’s Recycled Treatment Plant operation.  The intention of this requirement is to improve the general public’s access to information about the environmental performance of licensed facilities.
