## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of butanedioic acid, 2-methylene-, homopolymer, sodium salt; when used as an inert ingredient in a pesticide chemical formulation. Itaconix 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 butanedioic acid, 2-methylene-, homopolymer, sodium salt on food or feed commodities.
