Overview

• EPA’s Federal Register notice proposes major revisions to the TSCA Framework Rule, rescinding 2024 requirements to evaluate every condition of use and to issue a single whole‑substance risk determination.
• The agency would return to separate risk findings for each condition of use and regain discretion to exclude certain uses, exposure routes, or pathways, including those addressed under other environmental statutes.
• The proposal would allow workplace risk evaluations to consider engineering and administrative controls and personal protective equipment when supported by reasonably available information.
• For manufacturer‑requested risk evaluations, EPA would narrow information submission duties to what is in a company’s possession or control and what a similarly situated party would be expected to know.
• EPA cites timeliness, fit‑for‑purpose assessments, and the Supreme Court’s Loper Bright decision as rationale; trade groups have praised the changes, while environmental and health advocates warn they could weaken safeguards.
