EPA Issues Final SNURs for 145 Chemical Substances
On August 20, 2019, the U.S. Environmental Protection Agency (EPA) published in the Federal Register final significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for 145 chemical substances that are the subject of premanufacture notices (PMN). 84 Fed. Reg. 43266. According to EPA, the chemical substances are subject to orders issued by EPA pursuant to TSCA Section 5(e). The final SNURs require persons who intend to manufacture (defined by statute to include import) or process any of the 145 chemical substances for an activity that is designated as a significant new use by the rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA’s evaluation of the use, under the conditions of use for that chemical substance, 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 taken such actions as are required by that determination. The final SNURs will take effect October 21, 2019.
EPA notes that the final SNURs may also affect certain entities through pre-existing import certification and export notification rules under TSCA. Chemical importers are subject to TSCA Section 13 import certification requirements. Chemical importers must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA. Importers of chemicals subject to the SNURs must certify their compliance with the SNUR requirements. Any persons who export or intend to export a chemical substance that is the subject of the SNURs on or after September 19, 2019, are subject to the export notification provisions of TSCA Section 12(b) and must comply with export notification requirements.
