This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, polymer with butyl 2-propenoate and ethenylbenzene, also known as acrylic acid-butyl acrylate-styrene copolymer, when used as an inert ingredient in a pesticide chemical formulation. Momentive Performance Materials 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 and ethenylbenzene on food or feed commodities.
