## Abstract

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis modified Cry3A protein (mCry3A) and the genetic material necessary for its production in corn on field corn, sweet corn, and popcorn when applied/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 the temporary/tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis modified Cry3A protein (mCry3A) and the genetic material necessary for its production in corn. The temporary tolerance exemption will expire on October 15, 2006.
