This regulation establishes an exemption from the requirement of a tolerance for residues of sulfuric acid (CAS Reg. No. 7664-93-9), when used as an inert ingredient, in antimicrobial formulations, on food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils. Exponent, Inc., 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 sulfuric acid.
