## Abstract

This regulation establishes a temporary exemption from the requirement of a tolerance for residues of the Bacillus thuringiensis mCry51Aa2 protein in or on the food and feed commodities of cotton; cotton undelinted seed; cotton, gin byproducts; cotton, forage; cotton, hay; cotton, hulls; cotton, meal; and cotton, refined oil, when used as a plant-incorporated protectant (PIP) in accordance with the terms of Experimental Use Permit (EUP) No. 524-108. Monsanto Company 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 mCry51Aa2 protein. The temporary tolerance exemption expires on February 28, 2019.
