## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of hexanedioic acid, polymer with sodium 2- [(2-aminoethyl)amino]ethanesulfonate (1:1), 1,6-diisocyanatohexane, 2,2-dimethyl-1,3-propanediol, 1,2-ethanediamine and 1,6-hexanediol (CAS Reg. No. 67815-81-0); when used as an inert ingredient in a pesticide chemical formulation. ChemReg Compliance Solutions LLC on behalf of Covestro LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of hexanedioic acid, polymer with sodium 2-[(2-aminoethyl)amino]ethanesulfonate (1:1), 1,6- diisocyanatohexane, 2,2-dimethyl-1,3-propanediol, 1,2-ethanediamine and 1,6-hexanediol on food or feed commodities when used in accordance with these exemptions.
