## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, polymer with butyl 2- propenoate, ethenylbenzene and (1-methylethenyl) benzene, ammonium salt; when used as an inert ingredient in a pesticide chemical formulation. Spring Trading Company on behalf of BASF Corporation 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 2-propenoic acid, polymer with butyl 2-propenoate, ethenylbenzene and (1-methylethenyl) benzene, ammonium salt on food or feed commodities.
