Overview
- The proposed rule would add exemptions from historical PFAS reporting for de minimis concentrations below 0.1%, imported articles, certain byproducts, impurities, non‑isolated intermediates, and small research-and-development quantities.
- EPA would replace the existing schedule with a submission period that begins 60 days after the final rule takes effect and lasts three months.
- By excluding all imported articles, EPA projects the data collected would fall to about 2–3% of what the 2023 rule anticipated.
- Environmental groups and legal analysts warn the exemptions would limit transparency on PFAS uses and may be vulnerable in court because TSCA Section 8(a)(7) does not explicitly authorize them.
- The proposal is open for public comment in docket EPA-HQ-OPPT-2020-0549, with comments due by December 29, 2025.
