## Abstract

EPA is withdrawing a significant new use rule (SNUR) promulgated 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. EPA published this SNUR using direct final rulemaking procedures. EPA received a notice of intent to submit adverse comments on the rule. Therefore, the Agency is withdrawing this SNUR, as required under the expedited SNUR rulemaking process. Elsewhere in today's Federal Register, EPA is publishing (under separate notice and comment procedures) a proposed SNUR for these chemical substances.
