This regulation establishes tolerances for combined residues of fluroxypyr 1-methylheptyl ester [1-methylheptyl ((4-amino-3,5- dichloro-6-fluoro-2-pyridinyl)oxy)acetate] and its metabolite fluroxypyr [((4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy)acetic acid] in or on the raw agricultural commodities (RAC) wheat, barley, and oats as follows: 0.5 ppm (grain), 12 ppm (straw and forage), 20 ppm (hay), and 0.6 ppm (aspirated grain fractions). Because residues of fluroxypyr 1-methylheptyl ester and its metabolite fluroxypyr, free and conjugated, may occur in animal feeds derived from wheat, barley, and oats, the following meat and milk tolerances are also being established: 0.1 ppm (meat, fat, milk, and meat byproducts except for kidney) and 0.5 ppm (kidney). Dow AgroSciences LLC requested this tolerance under the Federal Food, Drug and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (Pub. L. 104-170).
