This regulation establishes time-limited tolerances for combined residues of pyridate (O-(6-chloro-3-phenyl-4-pyridazinyl)-S- octyl-carbonothioate), the metabolite 6-chloro-3-phenyl-pyridazine-4-ol and conjugates of 6-chloro-3-phenyl-pyridazine-4-ol in or on peppermint tops (leaves and stems) and spearmint tops (leaves and stems). 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 peppermint and spearmint. This regulation establishes a maximum permissible level for residues of pyridate in these food 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. The tolerances will expire and are revoked on December 31, 2001.
