Title: Significant New Use Rules on Certain Chemical Substances (19-6.B)

Description: AGENCY: Environmental Protection Agency (EPA)

ACTION: Final rule

SUMMARY: EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances which are the subject of premanufacture notices (PMNs). This action requires persons to notify EPA least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use by this rule. The required notification initiates EPA's evaluation of the chemical under the conditions of use 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 as a result of that determination.

DATES: This rule is effective on 28 September 2020. For purposes of judicial review, this rule shall be promulgated at 1 p.m. (e.s.t.) on 11 August 2020.
