This regulation establishes exemptions from the requirement of a tolerance for residues of tall oil fatty acids (CAS Reg. No. 61790- 12-3) when used as inert ingredients (solvent/carrier) in the following circumstances: In pesticide formulations applied to growing crops and raw agricultural commodities after harvest; in pesticides applied in/on animals, and in antimicrobial formulations for food contact surfaces. Spring Trading Company on behalf of Ingevity Corporation 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 maximum permissible levels for residues of tall oil fatty acids that are consistent with the conditions of these exemptions.
