Description
EPA published draft TSCA risk evaluation materials: draft risk evaluations for HHCB and phthalic anhydride and draft hazard assessments/supporting documents for o-dichlorobenzene and p-dichlorobenzene. EPA also announced Science Advisory Committee on Chemicals (SACC) peer review meetings (including a preparatory meeting) as part of the TSCA risk evaluation process. Compliance teams should review the drafts, consider submitting comments to the peer review docket, and assess whether conditions of use identified as presenting unreasonable risk could lead to future TSCA §6 risk management requirements if finalized.
