TSCA Section 5 Premanufacture Review of New Chemical Substances and Significant New Use Rules for New and Existing Chemical Substances (Proposed Rule)

Section 5 of the Toxic Substances Control Act (TSCA) provides EPA with a regulatory mechanism to monitor and, if necessary, control significant new uses of chemical substances. Section 5 authorizes EPA to determine by rule (i.e., a significant new use rule or SNUR), after considering all relevant factors, that a use of a chemical substance represents a significant new use. If EPA determines that a use of a chemical substance is a significant new use, section 5 requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture, import, or process the substance for that use. EPA uses the information obtained through this collection to evaluate the health and environmental effects of the significant new use. EPA may take regulatory actions under TSCA section 5, 6 or 7 to control the activities for which it has received a SNUR notice. These actions include orders to limit or prohibit the manufacture, importation, processing, distribution in commerce, use or disposal of chemical substances. If EPA does not take action, section 5 also requires EPA to publish a Federal Register notice explaining the reasons for not taking action. This information collection addresses the reporting and recordkeeping requirements inherent in TSCA section 5 significant new use rules.
