This regulation establishes time-limited tolerances for residues of 2, 6-Diisopropylnaphthalene, resulting from post-harvest applications to potato, in or on fat (cattle, goat, hog, horse, and sheep) at 0.8 part per million (ppm); liver (cattle, goat, hog, horse, and sheep) at 0.3 ppm; meat (cattle, goat, hog, horse, and sheep) at 0.1 ppm; meat byproducts (cattle, goat, hog, horse, and sheep) at 0.1 ppm; milk at 0.1 ppm; potato at 2.0 ppm; and potato, wet peel at 6.0 ppm. Loveland Products, Inc. had requested permanent tolerances (in or on whole potato and potato peels at 2 and 6 ppm, respectively) under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA). The time-limited tolerances will expire on August 1, 2009.
