This rule extends time-limited tolerances for residues of the pesticide buprofezin and its metabolite BF 12 in or on citrus fruit at 2.0 parts per million (ppm); dried citrus pulp at 10 ppm; cotton seed at 1.0 ppm; cotton gin byproducts at 20 ppm; milk at 0.03 ppm; and cattle, sheep, hogs, goats, and horse meat at 0.02 ppm, fat at 0.02 ppm, and meat byproducts at 0.5 ppm for an additional 1-year period, to July 31, 1999. This action is in response to EPA's granting of emergency exemptions under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act authorizing use of the pesticide on citrus and cotton. Section 408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA) 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.
