## Abstract

EPA is updating the chemical identities of significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 36 chemical substances which were the subject of premanufacture notices (PMNs). This action updates SNURs that were issued using generic chemical names but will now identify the specific chemical name and chemical abstract number.
