This regulation establishes temporary exemptions from the requirement of a tolerance for residues of Aspergillus flavus strains TC16F, TC35C, TC38B, and TC46G in or on the food and feed commodities of corn, field; corn, pop; and corn, sweet when used in accordance with the terms of Experimental Use Permit (EUP) No. 91163-EUP-1. Interregional Research Project Number 4 (IR-4) submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting these temporary tolerance exemptions. This regulation eliminates the need under FFDCA to establish a maximum permissible level for residues of Aspergillus flavus strains TC16F, TC35C, TC38B, and TC46G when used under the terms of EUP No. 91163-EUP-1. The temporary tolerance exemptions expire on June 30, 2020.
