EPA Issues Proposed Rule Adding Significant PFAS Reporting Exemptions

/in , ,

As anticipated, EPA has published a proposed rule that would introduce several significant exemptions to the one-time PFAS reporting requirements under the Toxic Substances Control Act (TSCA) PFAS reporting rule.

The proposal, published November 13, 2025, follows significant industry criticism of the 2023 rule’s expansive scope.  EPA first signaled that it was considering narrowing the rule’s requirements in May of this year, when the agency delayed its implementation for the second time.

“The proposed changes to improve reporting regulations will support [EPA] Administrator [Lee] Zeldin’s ‘Powering the Great American Comeback’ initiative by reducing regulatory reporting burdens and providing greater regulatory certainty to industry, resulting in a net reduction in cost while ensuring that EPA receives the PFAS data that are most relevant to the agency,” the agency said in a press release accompanying the proposed rule.

What are the Proposed Exemptions?

EPA proposes to exempt the following categories from the PFAS reporting requirements:

  • PFAS manufactured (including imported) in mixtures or products at concentrations of 0.1% or lower
  • Imported articles
  • Byproducts not used for commercial purposes
  • Impurities
  • Research and development chemicals
  • Non-isolated intermediates

These exemptions are similar to those under the TSCA Chemical Data Reporting (CDR) rule, with the addition of the 0.1% de minimis exemption.

EPA is also proposing to eliminate the streamlined reporting form for article importers and R&D manufacturers, because those entities would now be fully exempt under the proposed rule.  For the same reason, EPA would remove the alternative reporting deadline for small manufacturers that would exclusively report as article importers.

Changes to the Submission Period

EPA’s proposal would likely delay the start of the reporting period once again.  The current opening date is April 13, 2026, but under the proposed rule, the reporting window would begin 60 days after the final rule’s effective date.

If EPA issues a final rule in June 2026—as indicated in the Spring 2025 Unified Agenda—and the rule takes effect 30 days after publication, the reporting period would open in September 2026.  However, because the proposal was released a month earlier than the Unified Agenda projected, EPA may also finalize the rule ahead of schedule, potentially resulting in an earlier start date.

The proposal would also shorten the reporting window from six months to three months, with EPA claiming that submitters “have had adequate time to consider how they intend to comply with the rule.”

Statutory Basis

In the proposed rule, EPA argues that the exemptions would better align the regulation with TSCA section 8, which directs EPA to avoid duplicative reporting, minimize compliance costs on small manufacturers, and limit reporting obligations to persons likely to have relevant information.

EPA also cites TSCA section 2(c), which requires that EPA carry out the statute “in a reasonable and prudent manner” and to “consider the environmental, economic, and social impact of any action.”

At the same time, EPA notes that it may in the future determine that certain currently exempted information “is necessary to support particular regulatory actions.”

Comments on the proposed rule are due December 29, 2025.  More on the TSCA PFAS reporting rule can be found in our archive.
