## Abstract

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of 1-aminocyclopropane-1- carboxylic acid (ACC) in or on apples and stone fruits when used in accordance with the terms of the Experimental Use Permit (EUP) under EPA Number 73049-EUP-12. Valent BioSciences, LLC., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting a temporary exemption from the requirement of a tolerance for the use of ACC for a period of three years. This regulation eliminates the need to establish a maximum permissible level for residues of ACC resulting from use in accordance with the EUP No. 73049-EUP-12 under FFDCA. The temporary exemption from the requirement of a tolerance expires on July 6, 2023.
