This regulation establishes an exemption from the requirement of a tolerance for residues of 2-Propenoic acid, polymer with ethenylbenzene and (1-methylethenyl) benzene, sodium salt when used as an inert ingredient in a pesticide chemical formulation under 40 CFR 180.960. 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 ethenylbenzene and (1- methylethenyl) benzene, sodium salt on food or feed commodities.
