## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of the Bacillus thuringienisis Cry1B.34 protein (hereafter Cry1B.34 protein) in or on the food and feed commodities of corn, field; corn, sweet; and corn, pop when used as a Plant-Incorporated Protectant (PIP). Pioneer Hi-Bred International, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Cry1B.34 protein.
