This regulation establishes a time-limited tolerance for the inert ingredient, herbicide safener HOE-107892 (mefenpyr-diethyl) and its 2,4-dichlorophenyl-pyrazoline metabolites HOE-094270 and HOE-113225 in or on wheat grain and wheat straw. 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 herbicide safener on wheat grain and wheat straw in North Dakota and Montana. This regulation establishes a maximum permissible level for residues of the Herbicide safener HOE-107892 in this food commodity pursuant to section 408(l)(6) of the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996. The tolerances will expire and are revoked on August 1, 1998.
