Significant New Use Rules on Certain Chemical Substances (23-3.5e); (27 page(s), in English)

Proposed rule - EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs) and are also subject to a TSCA Order. A SNUR requires persons who intend to manufacture (defined by statute to include import) or process a particular chemical substance for an activity that is identified as a significant new use in the SNUR to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the conditions of use identified in the notification to EPA. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification, made an appropriate determination regarding that notification, and taken such actions as required by that determination.
