## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of nitric acid (CAS Reg. No. 7697-37-2) 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 a maximum level in the end-use concentration of 1,000 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. This regulation eliminates the need to establish a maximum permissible level for residues of nitric acid.
