This regulation establishes an exemption from the requirement of a tolerance for residues of diisopropanolamine when used as an inert ingredient (neutralizer or stabilizer) at no more than 10% in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest. United Phosphorus, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of diisopropanolamine.
