This regulation establishes an exemption from the requirement of a tolerance for residues of the Bacillus thuringensis Cry1B.868 and Cry1Da_7 proteins (hereafter Cry1B.868 and Cry1Da_7) when used as a Plant-Incorporated Protectant (PIP) in or on the food and feed commodities of corn: corn, field; corn, sweet, and corn, pop. Bayer U.S.--Crop Science 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.868 and Cry1Da_7 proteins.
