This regulation establishes a time-limited exemption from the requirement of a tolerance for residues of Bacillus mycoides isolate J in or on potato, when used in accordance with the terms of the section 18 emergency exemption. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on potato. The time-limited exemption from the requirement of a tolerance expires on December 31, 2015.
