This regulation establishes an extension of the temporary exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis Vip3Aa19 protein in cotton when applied/used as a plant-incorporated protectant (PIP). Syngenta Seeds, Inc. 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 the temporary tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of the Bacillus thuringiensis Vip3Aa19 protein in cotton when applied/used as a PIP on cotton. The temporary tolerance exemption expires on May 1, 2008.
