## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, polymer with ethenylbenzene and (1-methylethenyl)benzene with a minimum average molecular weight (in amu) of 2,000 (CAS Reg. No. 52831-04-6) when used as an inert ingredient in a pesticide chemical formulation. 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 on food or feed commodities.
