EPA posts/updates TSCA New Chemicals Division Reference Library with new technical guidance memoranda (e.g., MMO CAM hazard assessment, respirator/APF 1000 use; skin irritation/corrosion decision framework)

EPA updated the TSCA New Chemicals Division Reference Library (Section 5 program support) to include additional technical memoranda/guidance used in new chemical risk assessments and decision-making. These materials can affect PMN/SNUN strategy and supporting data expectations (e.g., approaches for assessing environmental hazards of cathode active material new chemical substances and guidance on exposure assumptions/industrial hygiene considerations, plus a decision framework for skin irritation/corrosion hazard identification). Compliance teams submitting or planning TSCA Section 5 notices should review these documents because they may influence EPA’s hazard/exposure assumptions and resulting determinations or required risk management conditions.
