## Abstract

EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 13 chemical substances which are the subject of premanufacture notices (PMNs). This action requires persons to notify EPA least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these 13 chemical substances for an activity that is designated as a significant new use by this rule. The required notification initiates EPA's evaluation of the intended use within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required as a result of that determination.
