EPA is proposing a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for chemical substances identified generically as complex strontium aluminum, rare earth doped, which were the subject of premanufacture notices (PMNs) P-12-22, P-12-23, P-12-24, P-12-25, and P-12-26. This action would require persons who intend to manufacture, import, or process any of the chemical 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 the activity before it occurs.
