U.S. Notifications
United States of America (USA/399: Dodecandioic acid, dihydrazide, thiophene, dibromo-3-hexyl)
EPA is proposing significant new use rules (SNURs) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for two chemical substances which were the subject of premanufacture notices (PMNs). The two substances are dodecandioic acid, 1, 12-dihydrazide (CAS No. 4080-98-2; PMNs P-01-759 and P-05-555) and thiophene, 2,5-dibromo-3-hexyl- (CAS No. 116971-11-0; PMN P-07-283). This action would require persons who intend to manufacture, import, or process either of these two substances for an activity that is designated as a significant new use by this proposed 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 that activity before it occurs.
