This regulation re-establishes a time-limited tolerance for residues of the insecticide Pyriproxyfen and its metabolites in or on stone fruits (Crop Group 12) at 0.1 part per million (ppm) for approximately an additional 2-year period. This tolerance will expire and is revoked on December 31, 2002. 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 stone fruits. 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 the Federal Insecticide, Fungicide, and Rodenticide Act.
