## Abstract

This regulation amends an exemption from the requirement of a tolerance for residues of zinc oxide (CAS Reg. No. 1314-13-2) when used as an inert ingredient in pesticide formulations applied to growing crops or raw agricultural commodities after harvest, to include use as a stabilizer, at a concentration not to exceed 15% by weight of the pesticide formulation. Nutrenare-AG, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an amended new use for an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of zinc oxide when used in accordance with the limitations of the exemption.
