Environmental monitoring

AGL is required under Environmental Protection Licence 2122 and Environmental Protection Licence 779 to monitor water and air emissions at specified locations and at various frequencies across Liddell and Bayswater Power Stations. The water and air monitoring is performed by third parties and analysed by NATA registered laboratories.

The information in the following links provides monitoring data prepared in accordance with the Environmental Protection Agency’s Requirements for publishing pollution monitoring data (October 2013).

It is also a legislative requirement that all sites with an Environment Protection Licence issued by the NSW Environmental Protection Authority prepare and implement a Pollution Incident Response Management Plan (PIRMP).

Ravensworth South Void 5A Dam

Rehabilitation of Ravensworth mine

Project overview and purpose

This mine was developed in 1987 by the Electricity Commission of NSW to supply coal to the nearby Bayswater and Liddell Power Stations. Mining operations commenced in 1987 and ceased in 2000, leaving a number of voids from the incomplete filling of the mined area with overburden, including Void 5. Sections of the mine have since been incorporated into adjoining mining operations, which are now managed in accordance with separate development consents by different companies.

Void 5 and the rehabilitated area immediately surrounding Void 5 within AGL land continues to be rehabilitated and managed by AGLM in accordance with DA 86/51.

DA 86/51 was modified in 2023 to include:

  • Changes to ash emplacement methodology within Void 5
  • Removal of redundant pumping infrastructure associated with Void 5
  • Provision for the receipt, stockpiling and use of capping material for Void 5 for final rehabilitation when the void is filled
  • Vegetation clearing to enable ongoing ash deposition in the Void 5 north arm
  • The introduction of flexible options for the Void 5 final landform to ensure it remains free draining and is aligned with neighbouring final mining landforms
  • Updating the boundary of DA 86/51 to reflect current land tenure and rehabilitation requirements
