TITLE: Significant New Use Rules on Certain Chemical Substances  
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 26 chemical substances which are the subject of premanufacture notices (PMNs) and 
deferring action on one chemical substance. The chemical substances are subject to Orders issued 
by EPA pursuant to section 5(e) of TSCA. This action requires persons who intend to manufacture 
(defined by statute to include import) or process any of these 2 6 chemical substances for an activity 
that is designated as a significant new use by this 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 has taken such  actions as are 
required by that determination.  
DATES: This rule is effective on 18 November 2019. For purposes of judicial review, this rule shall 
be promulgated at 1 p.m. (e.s.t.) on 2 October 2019.
