EPA is proposing new use rules for chemical substances that were the subject of premanufacture notices. The new rules will require manufactures and produces of those chemical substances to notify EPA 90 days before production. The 90 days would provide EPA adequate time to initiate the evaluation of use, under the conditions of use for that chemical substance, within the applicable review period. Interested parties may submit comments on the new rules until November 12, 2021.
