Williamtown Contamination Expert Panel

Williamtown Contamination Expert Panel

The Expert Panel was led by NSW Chief Scientist & Engineer Professor Mary O'Kane and consisted of a range of technical experts in contamination and health.  It also included senior representatives from the Environment Protection Authority (EPA), the Department of Health, the Department of Primary Industries and the Hunter Water Corporation.

The Expert Panel was established to explore the nature and extent of contamination from fire-fighting foams used historically at Williamtown RAAF base and recommend next steps.

The Panel provided scientific advice to the EPA and other NSW Government agencies to inform decisions relating to the protection of the community and the environment.

The Expert Panel worked in partnership and consulted regularly with the Williamtown Contamination Investigation Community Reference Group to ensure the community remained informed and updated.

Terms of Reference

1. Purpose

The Expert Panel has been established under Division 4 of the Protection of the Environment Administration Act 1991 for the purpose of providing informed scientific advice to the Environmental Protection Authority (EPA) to assist in developing the NSW Government's response to the Department of Defence in relation to investigations to characterise and manage its offsite contamination from Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) from the Williamtown RAAF Base.
The Expert Panel will also provide advice for NSW agencies to inform decisions they may need to make to protect the community and the environment in relation to matters such as the harvesting of oysters, fish and other agricultural products and the use of ground and surface water in areas potentially affected by the offsite contamination.

2. Functions and Role of the Expert Panel

The functions of the Expert Panel are to:
1. Assess available information on contamination from the Williamtown RAAF Base and advise agencies on factors influencing the retention of the temporary measures already in place and the need for any additional measures to manage potential risks, including to recreational and commercial fishing, oyster harvesting, bore water usage and agricultural activities.
2. Provide advice to the EPA on whether and what additional investigations or studies are needed to be undertaken by the Department of Defence and their consultants, to assist in refining risk assessment and management measures related to the PFOS and PFOA contamination originating from the Williamtown RAAF Base.
3. Review and provide advice on proposed remediation strategies to be undertaken by the Department of Defence to address migration of contamination from the Williamtown RAAF Base and advice on the need for further investigations and/or long-term monitoring, and reporting mechanisms for the data and information from these activities.
4. Provide a source of informed expert advice to the EPA and through them to the Department of Defence on guidance to the local community and relevant stakeholders. The Expert Panel will operate for 12 months from the date of its formation. The term of the Expert Panel can be extended by the EPA Chair and CEO if required.
The Panel was extended until 30 June 2017. It has since transitioned into the NSW PFAS Expert Panel.
