EPA proposes amendments to TSCA risk evaluation framework rule (procedures for chemical risk evaluation)

EPA announced a proposed rule to revise the procedures for conducting TSCA risk evaluations for existing chemicals (the TSCA risk evaluation framework/procedural rule). The proposal describes changes affecting how EPA makes risk determinations (including around conditions of use and exposure pathways), treatment of occupational exposure controls (e.g., PPE/engineering controls), and related procedural/definition updates. Companies with substances undergoing TSCA risk evaluation should assess potential impacts on evaluation scope and assumptions and consider submitting comments in the associated docket once the proposal is published in the Federal Register.
