This regulation establishes tolerances for combined residues of fipronil and its two metabolites and one photodegradate in or on potato and potato, wet peel, and indirect or inadvertent residues of fipronil and its two metabolites and one photodegradate in or on wheat, forage; wheat, grain; wheat, hay; and wheat, straw. BASF Corporation requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). In addition, this establishes time-limited tolerances for combined residues of fipronil in or on turnip and rutabaga. This action is in response to EPA's granting of emergency exemptions under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on turnip and rutabaga. This regulation establishes maximum permissible levels for combined residues of fipronil in these food commodities. The tolerances for rutabaga and turnip expire and are revoked on December 31, 2010.
