## Abstract

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis Cry2Ae in or on cotton and its food and feed commodities when used as a Plant-Incorporated Protectant (PIP) in accordance with the terms of Experimental Use Permit 264-EUP-143. Bayer CropScience LP submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the temporary tolerance exemption. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis Cry2Ae. The temporary tolerance exemption expires on December 31, 2012.
