What changed

The U.S. Environmental Protection Agency (EPA) has proposed significant modifications to its existing PFAS reporting regulations under TSCA Section 8(a)(7). These changes aim to reduce the compliance burden on manufacturers and importers, which the agency states was nearly $1 billion under the previous rule finalized in October 2023. Key proposed exemptions include PFAS in mixtures below 0.1% concentration, imported articles, certain byproducts, impurities, R&D chemicals, and non-isolated intermediates. Technical corrections to data fields and submission periods are also included.

This proposal is open for a 45-day public comment period, starting upon publication in the Federal Register, under docket #EPA-HQ-OPPT-2020-0549. Regulated entities, particularly small businesses and importers, should review the proposed exemptions and technical corrections to assess their impact. The EPA intends to collect more relevant PFAS data without imposing what it describes as "ridiculous requirements" or "crushing regulatory burdens." The agency emphasizes that these changes align with the goal of collecting necessary information without overburdening businesses, consistent with TSCA's intent.

What to do next

Review proposed exemptions for PFAS reporting under TSCA Section 8(a)(7).
Submit comments on the proposed changes to docket #EPA-HQ-OPPT-2020-0549 within 45 days of Federal Register publication.

EPA Proposes Changes to Make PFAS Reporting Requirements More Practical and Implementable, Reducing Regulatory Burden

November 10, 2025

Contact Information EPA Press Office
(press@epa.gov) WASHINGTON – Today, U.S. Environmental Protection Agency (EPA) released a proposal to improve the scope of its p erfluoroalkyl and polyfluoroalkyl substances (PFAS) reporting regulations under the Toxic Substances Control Act (TSCA) to make them more practical and implementable and reduce unnecessary, or potentially duplicative, reporting requirements for businesses while maintaining the ability to obtain important use and safety information on PFAS.

In October 2023, the Biden Administration EPA finalized a one-time PFAS reporting and recordkeeping regulation under TSCA section 8(a)(7) that requires manufacturers (including importers) of PFAS in any year between 2011-2022 to report data to EPA related to exposure and any existing environmental and health effects. The rule exemplifies regulatory overreach by imposing a nearly billion-dollar compliance burden on industry without establishing any clear framework for utilizing the collected data or demonstrating how it advances environmental protection goals. The rule's lack of practical implementation standards, evidenced by significant IT system failures and administrative delays, represents poor regulatory design that unnecessarily burdens small businesses and importers while failing to achieve meaningful environmental outcomes.

The proposed changes to improve reporting regulations will support Administrator 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. These proposed changes will also deliver on Administrator Zeldin’s April 28, 2025, commitment to “implement [TSCA] section 8(a)7 to smartly collect necessary information, as Congress envisioned and consistent with TSCA, without overburdening small businesses and article importers.”

“This Biden-era rule would have imposed crushing regulatory burdens and nearly $1 billion in implementation costs on American businesses,” *said EPA Administrator Lee Zeldin*. “Today’s proposal is grounded in commonsense and the law, allowing us to collect the information we need to help combat PFAS contamination without placing ridiculous requirements on manufacturers, especially the small businesses that drive our country’s economy.”

The exemptions and modifications that EPA is proposing would maintain important reporting requirements on PFAS while exempting reporting on activities that manufacturers are least likely to know or reasonably determine. The proposed exemptions are:

PFAS manufactured (including imported) in mixtures or products at concentrations 0.1% or lower;
Imported articles;
Certain byproducts;
Impurities;
Research and development chemicals; and
Non-isolated intermediates.
The agency is also proposing technical corrections to clarify what must be reported in certain data fields and to adjust the data submission period.

Upon publication of the Federal Register notice, EPA will accept comments on the proposed changes for 45 days in docket #EPA-HQ-OPPT-2020-0549 on www.regulations.gov. View a prepublication version of this proposal here.
