Title: Significant New Use Rule (SNUR); Chemical-Specific SNURs To Extend Provisions of Section 5(e) Orders 
Abstract: Section 5(a)(2) of the Toxic Substances Control Act (TSCA) authorizes EPA to determine that a use of a chemical substance is a "significant new use." After considering all relevant factors, including those listed in TSCA section 5(a)(2), EPA makes this determination by promulgating Significant New Use Rules (SNURs). These regulations require persons who intend to manufacture, import, or process a chemical substance contained in a SNUR for an activity that is designated as a significant new use 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. For chemicals which were the subject of premanufacture notices (PMNs) and for which EPA made a determination that the manufacture, processing, distribution, use or disposal may present an unreasonable risk, the Agency may issue a section 5(e) consent order to limit these activities. The Agency generally issues "5(e)" SNURs to extend the controls prescribed in these consent orders to other manufacturers and processors by designating the manufacture, processing, distribution, use or disposal of the substances without the specified controls as significant new uses. For chemicals which were the subject of PMNs, EPA may also promulgate "non-5(e) SNURs" when the Agency did not find that the chemical’s manufacture, processing, distribution, use or disposal, as described in the PMN, triggered the determinations set forth under TSCA section 5(e) but did find that certain changes in the chemical’s manufacture, processing, distribution, use or disposal could result in increased exposures to or releases of the substance. Under the Expedited Follow-up Rule (EFUR), 40 CFR part 721, subpart D, EPA routinely issues batch direct final section 5(e) and non-5(e) SNURs.
