## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of butanedioic acid, 2-methylene-, polymer with 1,3-butadiene, ethenylbenzene and 2-hydroxyethyl 2-propenoate; when used as an inert ingredient (emulsifier or binder) in a pesticide chemical formulation. Keller and Heckman on behalf of Trinseo 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 butanedioic acid, 2-methylene-, polymer with 1,3- butadiene, ethenylbenzene and 2-hydroxyethyl 2-propenoate on food or feed commodities.
