The U.S. Environmental Protection Agency (USEPA) has announced a proposal to improve its perfluoroalkyl and polyfluoroalkyl substances (PFAS) reporting regulations under the Toxic Substances Control Act (TSCA). The goal of the proposed changes is to make the reporting requirements more practical and implementable.
The update aims to improve a Biden Administration era PFAS reporting and recordkeeping regulation under TSCA section 8(a)(7) that required manufacturers and importers of PFAS to report information related to exposure or existing environmental and health effects.
USEPA says the proposed changes 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.”
The exemptions and modifications proposed by USEPA maintain important PFAS reporting requirements 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
- Non-isolated intermediates
USEPA says it is also proposing technical corrections to clarify what must be reported in certain data fields and to adjust the data submission period.
Public comments will be accepted via the Federal Register through December 29, 2025.
