## Abstract

This regulation establishes exemptions from the requirement of a tolerance for residues of methyl isobutyrate (CAS Reg. No. 547-63-7) and for residues of isobutyl isobutyrate (CAS Reg. No. 97-85-8) when used as inert ingredients (solvents) applied to growing crops or raw agricultural commodities after harvest. Jeneil Biosurfactant Company 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 methyl isobutyrate and isobutyl isobutyrate when used in accordance with the conditions.
