## Abstract

EPA is finalizing an amendment to the significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for 2-Propen-1- one, 1-(4-morpholinyl)- (CAS No. 5117-12-4). This action requires persons who intend to manufacture, import, or process the chemical substance for a use that is designated as a significant new use by this final rule to notify EPA at least 90 days before commencing that activity. EPA believes that this action is necessary because the chemical substance may be hazardous to human health. 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.
