EPA releases draft TSCA risk evaluation/hazard materials for HHCB, phthalic anhydride, o‑DCB and p‑DCB and announces SACC peer review meeting (June 8–12, 2026)

EPA published draft TSCA risk evaluation documents for HHCB and phthalic anhydride and draft hazard assessment/supporting materials for o-dichlorobenzene and p-dichlorobenzene, and announced a Science Advisory Committee on Chemicals (SACC) peer review meeting scheduled for June 8–12, 2026 (with a preparatory meeting on May 26, 2026). EPA highlighted that the draft risk evaluation for phthalic anhydride identifies unreasonable risks for certain worker and consumer exposures, which could drive later TSCA Section 6 risk management if finalized. Compliance teams should review draft findings, prepare public comments for the peer review docket, and anticipate potential downstream risk management actions for affected conditions of use.
