This regulation establishes an exemption from the requirement of a tolerance for residues of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1- propanesulfonic acid monosodium salt polymer with 2-propenoic acid, 2- methyl-, C12-16 alkyl esters; when used as an inert ingredient in a pesticide chemical formulation. Lamberti USA, Incorporated 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-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid monosodium salt polymer with 2-propenoic acid, 2-methyl-, C12-16 alkyl esters on food or feed commodities.
