This regulation establishes an exemption from the requirement of a tolerance for residues of acetic acid ethenyl ester, polymer with sodium 2-methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1), hydrolyzed (CAS No. 924892-37-5); when used as an inert ingredient in a pesticide chemical formulation. Celanese Ltd. 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 acetic acid ethenyl ester, polymer with sodium 2- methyl-2-[(1-oxo-2-propen-1-yl)amino]-1-propanesulfonate (1:1), hydrolyzed on food or feed commodities.
