Bacillus Thuringiensis Vip3Aa20 Protein and the Genetic Material Necessary for its Production in Corn; Extension of Temporary Exemption From the Requirement of a Tolerance

This regulation extends the temporary exemption from the requirement of a tolerance for residues of Bacillus thuringiensis Vip3Aa20 protein in corn when applied or used as a plant-incorporated protectant. 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 that the temporary tolerance exemption be extended. This regulation eliminates the need to establish a maximum permissible level for residues of the Bacillus thuringiensis Vip3Aa20 protein in corn when applied or used as a plant- incorporated protectant on field corn, sweet corn, and popcorn. The temporary tolerance exemption expires on October 31, 2009.
