EPA clarifies scope of PFOA phase-out after court ruling
The story at a glance
The US Environmental Protection Agency has updated a fact sheet to clarify that the PFOA phase-out applied to companies in its 2010/2015 stewardship programme. The agency says companies outside that programme may still produce, import and use PFOA, and notes that some PFOS uses continue. This is a clarification of the programme’s scope, not a newly imposed ban or a reversal of participating companies’ commitments.1
The update comes after a federal appeals court vacated EPA orders against Inhance Technologies, which fluorines plastic containers. The court found that EPA had used the wrong provision of the Toxic Substances Control Act for the company’s decades-old process. It said the agency could pursue regulation under another provision, subject to that provision’s requirements.2
The story in brief
What you need to know
- EPA’s programme asked eight companies to reduce PFOA emissions and the compound’s content in products, then work towards eliminating them. EPA says those participating companies reported meeting the programme goals. The fact sheet does not describe this as a phase-out covering every company.1
- The updated fact sheet says companies outside the programme may produce, import and use PFOA. It also records that some uses of PFOS continue. The sources do not establish how many companies currently produce or import PFOA, or in what quantities.1
- In 2024, the Fifth Circuit vacated EPA’s orders against Inhance. Its ruling was about the agency’s statutory authority: EPA could not use TSCA Section 5 to regulate the company’s existing process as a significant new use. The court identified Section 6 as a possible route, subject to its legal requirements.2
- EPA’s assessment identified risks of concern from PFAS generated during Inhance’s container-fluorination process, including migration into container contents. Its conclusions on exposure and risk were qualitative and included uncertainties. Inhance disputes measurable PFOA leaching and describes any PFOA as an impurity.4
- The available reporting does not show that the court found Inhance’s process risk-free, nor that EPA has since taken a new regulatory action against the company. The ruling left open a different regulatory route, but did not itself establish what the agency will do.2
Conservation context
Why this matters
The distinction between a voluntary programme and a blanket restriction matters when assessing how far a chemical phase-out reaches. The reporting also highlights how the legal basis for regulatory action can affect whether controls on a long-running industrial process stand, while leaving questions about exposure and current production unresolved.124
The developing story
What happens next
A key unresolved question is whether EPA will seek to regulate Inhance’s process under TSCA Section 6. Further clarity on any current PFOA production outside the programme, and on migration from treated containers under real-world conditions, would also address gaps identified in the reporting.214
Established evidence
What we know
- The EPA fact sheet was updated on 19 September 2026 and distinguishes participating programme companies from companies outside it.1
- Eight companies participated in the stewardship programme, and EPA says they reported meeting its goals.1
- The Fifth Circuit vacated EPA’s orders against Inhance on statutory-authority grounds in March 2024.2
- EPA’s assessment identified potential migration of PFAS generated in the container-fluorination process, while describing uncertainty in exposure and risk conclusions.4
Open questions
What we don't know
- Which companies currently produce or import PFOA outside the stewardship programme, and in what quantities.13
- The present-day extent and levels of PFOA migration from Inhance containers under real-world use conditions.4
- Whether EPA will pursue regulation of Inhance’s process under TSCA Section 6.2
- The full scale of any PFOA production or imports outside the programme is not established by the supplied reporting.134
