This regulation establishes time-limited tolerances for residues of triclopyr and its 3,5,6-trichloro-2-pyridinol metabolite in or on fish at 0.2 ppm and shellfish at 5.0 ppm. This action is in response to EPA's granting of an emergency exemption under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act authorizing use of the pesticide on aquatic sites. This regulation establishes a maximum permissible level for residues of triclopyr in these commodities pursuant to section 408(l)(6) of the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996. These tolerances will expire and are revoked on December 31, 1998.
