## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of propylene glycol (CAS Reg. No. 57-55-6) when used as an inert ingredient in antimicrobial formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils under our regulations. Exponent on behalf of Ecolab, Inc. 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 propylene glycol.
