This regulation establishes an exemption from the requirement of a tolerance for residues of Bacillus thuringiensis var. aizawai strain PS811 (Cry1F insecticidal protein) and the genetic material necessary for its production in cotton when applied/used as a plant- incorporated protectant. DowAgro Sciences, LLC submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis var. aizawai strain PS811 (Cry1F insecticidal protein) and the genetic material necessary for its production in cotton when used as a plant-incorporated protectant.
