## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of Adipic acid when used as an inert ingredient in antimicrobial pesticide formulations applied to food- contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils at an end-use concentration not to exceed 100 parts per million (ppm). 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 for adipic acid. This regulation eliminates the need to establish a maximum permissible level for residues of adipic acid when used in accordance with this exemption.
