## Abstract

EPA is finalizing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for three chemical substances that were the subject of premanufacture notices (PMNs). This action requires persons who intend to manufacture (including import) or process any of the 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 would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit the activity before it occurs.
