What it contains

The purpose of this interim position statement is to outline EPA’s current state of knowledge regarding per-and polyfluorinated alkyl substances (PFAS). It also provides guidance on EPA’s current approach to the assessment and management of PFAS sources and how to approach potential contamination. This document is intended to be updated as new information becomes available. The Department of Health and Human Services has published a literature review and report on the health effects of PFAS.

EPA has developed a legislative instrument called a designation under the new EP Act 2017, which sets the threshold at which PFAS contaminated soil can be used as fill material, consistent with EPA’s Interim position statement on PFAS. The designation is a fixed term regulatory tool that will allow industry to self-assess waste soil against the thresholds in the instrument.

Under the EP Act 1970 this process was carried out with reference to the thresholds in EPA’s Interim position statement on PFAS, which was not set out in any regulation. This new instrument strengthens the legal status of the thresholds used to determine whether the waste soil is safe to use as fill material.

It has been developed as a fixed term regulatory tool until 30 June 2023 which allows time to undertake more scientific assessment of the thresholds (currently considered to be very conservative) to ensure the thresholds continue to convey the best available science on the impact of PFAS contamination in soil.
