Significant New Use Rules on Certain Chemical Substances and Notification on Certain Substances for Which Significant New Use Rules are Not Being Issued

EPA is promulgating significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for 65 chemical substances which were the subject of premanufacture notices (PMNs). Thirteen of these chemical substances are subject to TSCA section 5(e) consent orders issued by EPA. This action requires persons who intend to manufacture, import, or process any of these 65 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. This direct final rule also provides notification on two substances for which EPA has decided not to issue significant new use rules at this time.
