Proposed Revocation of Significant New Uses of Certain Chemical Substances

Resumen

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