USA proposed significant new use rules on certain chemical substances EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs). They are either the subject of Orders issued by EPA under TSCA or have received a "not likely to present an unreasonable risk" determination pursuant to TSCA. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use 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 has taken such actions as are required by that determination. Products covered: Chemical substances; Environmental protection (ICS 13.020), Production in the chemical industry (ICS 71.020), Products of the chemical industry (ICS 71.100) HS Codes: 28, 29, 30, 31, 32, 33, 34, 35 Proposed date of adoption: To be determined Proposed date of entry into force: To be determined Final date for comments: 6 January 2020 |
