## Abstract

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of Bacillus thuringiensis eCry3.1Ab protein in corn in or on the food and feed commodities of corn; corn, field; corn, sweet; and corn, pop, when used as a plant- incorporated protectant in accordance with the terms of Experimental Use Permit 67979-EUP-8. Syngenta Seeds, Incorporated submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting a temporary exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis eCry3.1Ab protein in corn under the FFDCA. The temporary tolerance exemption expires on June 1, 2012.
