This regulation re-establishes time-limited tolerances for combined residues of the insecticide imidacloprid (1-[6-chloro-3- pyridinyl) methyl]-N-nitro-2-imidazolidinimine) and its metabolites containing the 6-chloropyridinyl moiety, all expressed as 1-[(6-chloro- 3-pyridinyl)methyl]-N-nitro-2-imidazolidinimine, in or on turnip, roots at 0.3 parts per million (ppm); turnip, tops at 3.5 ppm; beet, garden, roots at 0.3 ppm; and beet, garden, tops for an additional 2-year period. These tolerances will expire and are revoked on June 30, 2004. 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 turnips and garden beets. Section 408(l)(6) of the Federal Food, Drug, and Cosmetic Act requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under section 18 of FIFRA.
