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 component of food contact sanitizing solutions applied to all food contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. 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.
