## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid polymer, with 1,3- butadiene and ethenylbenzene, minimum number average molecular weight (in AMU) 9400 (CAS Reg. No. 25085-39-6); 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 1,3-butadiene and ethenylbenzene on food or feed commodities.
