This regulation establishes time-limited tolerances for residues of tetraconazole in or on sugar beets, and sugar beet-related commodities, and for secondary residues of triazole on animal commodities from livestock fed sugar beet by-products. This action is in response to EPA's granting of an emergency exemption under provisions of section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act, authorizing use of the pesticide on sugar beets. This regulation establishes maximum permissible levels for residues of tetraconazole [(+/-)-2-(2,4-dichlorophenyl)-3-(1H-1,2,4-triazol-1-yl) propyl 1, 1,2,2-tetrafluoroethyl ether] in the effected food commodities. The tolerances will expire and will be revoked on December 31, 2001.
