This regulation establishes an exemption from the requirement of a tolerance for residues of Pseudomonas chlororaphis IPD072Aa protein in or on maize (hereafter IPD072Aa protein) 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. 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 IPD072Aa protein.
