This regulation establishes an 18-month exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis Cry1A.105 protein in or on the food and feed commodities cotton seed, cotton seed oil, cotton seed meal, cotton hay, cotton hulls, cotton forage and cotton gin byproducts when used as a plant-incorporated protectant. Monsanto Company submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting a time-limited exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis Cry1A.105 protein in or on the food and feed commodities cotton seed, cotton seed oil, cotton seed meal, cotton hay, cotton hulls, cotton forage and cotton gin byproducts. This tolerance exemption expires and is revoked on November 22, 2010.
