This regulation establishes time-limited tolerances for combined residues of thiophanate-methyl and its metabolite methyl 2- benzimidazoyl carbamate (MBC) in or on cotton and cotton, gin byproducts. 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 cotton. This regulation establishes a maximum permissible level for residues of thiophanate-methyl in these feed commodities. These tolerances will expire and are revoked on December 31, 2007.
