## Abstract

EPA is promulgating significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 107 chemical substances which were the subject of premanufacture notices (PMNs). Eight of these chemical substances are subject to TSCA consent orders issued by EPA. This action requires persons who intend to manufacture, import, or process any of these 107 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs.
