Welcome to the third article in our regular series, The Perils of PFAS. This series is designed to help you navigate the issues surrounding PFAS, a contaminant which is garnering greater scrutiny as the knowledge about its impacts continues to evolve.
This article explains the key changes in the recently published PFAS National Environmental Management Plan 2.0 (PFAS NEMP 2.0), which provides the latest national guidance on managing PFAS contamination.
Environmental regulators in Australia recognise PFAS as a priority contaminant due to its widespread use, resistance to degradation and uncertain human health and environmental impacts.
In February 2018, the first PFAS National Environmental Management Plan (PFAS NEMP 1.0) was published by the Heads of EPAs Australia and New Zealand (HEPA), which is an informal alliance between Commonwealth, State and Territory environmental regulators, in collaboration with the Commonwealth Department of Agriculture, Water and Environment (formerly the Department of Environment and Energy).
The PFAS NEMP 1.0 aimed to provide nationally consistent guidance for managing PFAS contamination, to be implemented through individual mechanisms and regulatory activities at the State and Territory level.
Due to the evolving nature of the science surrounding PFAS contamination and its impacts, the PFAS NEMP 1.0 established a regular ongoing informal and formal review process and identified priority areas for future work.
During 2018, the National Chemicals Working Group of HEPA commenced work on a draft PFAS NEMP 2.0, with the aim of clarifying the general guidance provided in the PFAS NEMP 1.0 and providing new guidance on the following priority areas:
In 2019, the public was consulted on the draft PFAS NEMP 2.0 in each State and Territory jurisdiction.
In early May 2020, the final PFAS NEMP 2.0 was published. The PFAS NEMP 2.0 has since been endorsed by the Environment Minister (or equivalent) in the Commonwealth and most State and Territory jurisdictions, and replaces the PFAS NEMP 1.0 in those jurisdictions.1
As such, the PFAS NEMP 2.0 should now be considered when assessing, managing and remediating confirmed and potential PFAS contaminated sites. In some circumstances, it may also be necessary to consider whether past reports should be updated to accommodate the changes reflected in the PFAS NEMP 2.0.
We set out below a brief summary of key changes in the PFAS NEMP 2.0.
The PFAS NEMP 2.0 revises the human health and ecological guideline values for PFAS contamination, which are used to identify whether PFAS contamination poses an unacceptable risk to human health and/ or the environment. If the concentration of PFAS is found to exceed any of the applicable guideline values, further investigation, and potentially regulation, will be required.
In summary, the key changes to the environmental guidelines values in the PFAS NEMP 2.0 are:
The PFAS NEMP 2.0 notes that, in some circumstances, the guideline value may be overprotective and provides examples where site-specific characteristics may justify the use of a higher value.
The PFAS NEMP 2.0 provides new guidance on the beneficial reuse of PFAS-contaminated soil without a detailed risk assessment.
A decision tree is provided to guide consideration as to whether re-use is suitable (see Figure 5, PFAS NEMP 2.0). This decision tree must be applied in consultation with the relevant State or Territory environmental regulator. It does not replace environmental legislation, and in many cases, a licence and/ or approval will also be required.
Importantly, the following criteria must be satisfied:
The PFAS NEMP 2.0 recognises that further work is required in collaboration with industry to develop PFAS management criteria for wastewater.
In the meantime, the PFAS NEMP 2.0 encourages water utilities and authorities to develop a PFAS Management Framework to demonstrate compliance to the regulators and to manage the risks that may otherwise arise once management criteria are established. The PFAS Management Framework should address all stages of the wastewater treatment life cycle including the input, processing and output stages. An example framework is provided in Appendix D to the PFAS NEMP 2.0.
Finally, the PFAS NEMP 2.0 provides new guidance for the on-site stockpiling, storage and containment of PFAS-containing material, during the investigation, remediation and/or construction phases of a project or where other treatment/ remediation options are not yet available. This guidance is relevant to projects involving large volumes of material such as:
The PFAS NEMP 2.0 sets out a risk-based management approach for the design of stockpiling, storage and containment infrastructure, whereby the design is proportionate to the level of assessed risk and the length of time the material is proposed to be stored.
Detailed guidance is provided for the design, construction and management of this infrastructure, including the key considerations and requirements. For example, an environmental management, maintenance, and operating plan may be required.
Consideration should also be given to legislative requirements, such as whether a licence and/or approval must be obtained.
The PFAS NEMP will continue to be regularly reviewed and updated to reflect scientific developments. Work is already underway on a draft PFAS NEMP 3.0, which is expected to be released for public comment during 2021.
In addition, a formal review of the PFAS NEMP must take place every five years, with the first formal review scheduled for 2023.
