This regulation establishes time-limited tolerances for residues of the inert ingredient, herbicide safener HOE-107892 and its metabolites HOE-113225, HOE-109453, and HOE-094270 in or on barley grain, barley hay, barley straw, and the processed by-products of barley grain: pearled barley, bran, and flour. 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 fenoxaprop formulated with HOE-107892 on barley. This regulation establishes maximum permissible levels for residues of HOE-107892 and its metabolites HOE 113225, HOE-109453, and HOE-094270 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. These tolerances will expire and be revoked on February 1, 2000.
