Proposed Category for Persistent, Bioaccumulative, and Toxic Chemical Substances

EPA has grouped new chemical substances with similar structural and toxicological properties into working categories. These groupings enable the Toxic Substances Control Act (TSCA) section 5(a)(1), Premanufacture Notice (PMN) submitters, and EPA reviewers to benefit from accumulated data and decisional precedents. The establishment of over 45 of these chemical categories has streamlined the process for Agency review of and regulatory follow-up on new chemical substances. Consistent with TSCA section 26(c), which allows EPA action under TSCA with respect to categories of chemical substances or mixtures, EPA is developing a category of persistent, bioaccumulative, and toxic (PBT) chemical substances. This notice solicits comments on proposed criteria for identifying PBT chemical substances and their supporting scientific rationale.
