Environmental assessment for the Warragamba Dam Raising project commenced in September 2017. The studies and survey undertaken will provide important data for the Environmental Impact Statement (EIS), which will be made available for public review and comment. The dates for the public review period will be posted on this website and available in community updates.

The EIS will be prepared in accordance with the Environmental Planning and Assessment Act 1979 and the NSW Department of Planning and Environment Secretary’s Environmental Assessment Requirements (SEARs).

The project has been declared a Controlled Action under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 due to the likely impact on matters of national environmental significance including:

  • World Heritage properties (the Greater Blue Mountains World Heritage Area and National Heritage Place)
  • National Heritage places
  • Listed threatened species and communities.

The environmental assessment will be undertaken through the Bilateral Agreement between the NSW and Australian governments.
