## Abstract

This regulation extends a temporary exemption from the requirement of a tolerance for residues of Bacillus thuringiensis eCry3.1Ab protein in corn 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 (EUP) No. 67979-EUP-8. Syngenta Seeds, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting to extend the temporary tolerance exemption that was set to expire on June 1, 2012. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus thuringiensis eCry3.1Ab protein in corn. The temporary tolerance exemption now expires on March 1, 2013.
