## Abstract

EPA is revoking significant new use rules (SNURs) for 12 chemical substances promulgated under section 5(a)(2) of the Toxic Substances Control Act (TSCA). Based on the new data the Agency no longer finds that activities not described in the corresponding TSCA section 5(e) consent orders or the premanufacture notices (PMN) for these chemical substances may result in significant changes in human or environmental exposure.
