n-Butyl 3-hydroxybutyrate and Isopropyl 3-hydroxybutyrate; Exemption From the Requirement of a Tolerance

This regulation establishes exemptions from the requirement of a tolerance for residues of n-butyl 3-hydroxybutyrate (CAS Reg. No. 53605-94-0) and isopropyl 3-hydroxybutyrate (CAS Reg. No. 54074-94-1) when used as inert ingredients (solvents) in pesticide formulations applied to growing crops or raw agricultural commodities after harvest; to animals; and to food contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. Steptoe and Johnson, on behalf of Eastman Chemical Company, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of these exemptions from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of n-butyl 3-hydroxybutyrate and isopropyl 3-hydroxybutyrate when applied or used under these conditions.
