## Abstract

This regulation establishes a permanent 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 an exemption from the requirement of a tolerance. 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.
