## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-methyl-1,3-propanediol (CAS Reg. No. 2163-42-0) when used as an inert ingredient in pesticide formulations applied to growing crops and raw agricultural commodities after harvest, and when used as an inert ingredient solvent and/or surfactant in pesticide formulations applied to animals (used for food). Lyondell Chemical 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 2-methyl-1,3-propanediol.
