NOTIFICATION
1. Member to Agreement notifying:   UNITED STATES
If applicable, name of local government involved:
2. Agency responsible:   Environmental Protection Agency (EPA)
3. Products covered (provide tariff item number(s) as specified in national schedules
deposited with the WTO; ICS numbers should be provided in addition, where
applicable):  Products that use the pesticide Imazethapyr in or on canola seed and its
metabolite 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-5-(1-
hydroxyethyl)-3-pyridine carboxylic acid, and its metabolite 5-[1-(beta-D-glucopyranosyloxy)ethyl]-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-
2-yl]-3-pyridinecarboxylic acid in or on animal feed, nongrass, forage and hay group.
4. Regions or countries likely to be affected, to the extent relevant or practicable:  Any
US trading partners
5. Title, language and number of pages of the notified document:  Imazethapyr;  Pesticide
Tolerance (available in English, pages).
6. Description of content:  This regulation establishes tolerances for residues of imazethapyr,
2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl]-5-ethyl-3-pyridinecarboxylic acid in/on canola seed (import commodity only), and the combined residues of
imazethapyr, its metabolite 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-
imidazol-2-yl]-5-(1-hydroxyethyl)-3-pyridine carboxylic acid, and its metabolite 5-[1-
(beta-D-glucopyranosyloxy)ethyl]-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-
imidazol-2-yl]-3-pyridinecarboxylic acid in or on animal feed, nongrass, forage and haygroup.  BASF requested these tolerances under the Federal Food, Drug, and Cosmetic Act
(FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA).
After analysis of the submitted residue chemistry data, EPA determined that appropriate
tolerances for nongrass animal feed differ from those proposed by the registrant. EPAdetermined that available field trial data support the following tolerances for the combined
residues of the herbicide imazethapyr, 2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-
1H-imidazol-2-yl]-5-ethyl-3-pyridine carboxyli c acid, and its metabolites 2-[4,5-dihydro-4-
methyl-4-(1-methylethyl-5-oxo-1H-imidazol-2-yl]-5-(1-hydroxyethyl)-3-pyridine
carboxylic acid and 5-[1-(beta-D-glucopyranosyloxy)ethyl]-2-[4,5-dihydro-4-methyl-4-(1-
methylethyl)-5-oxo-1H-imidazol-2-yl]-3-pyridinecarboxylic acid, applied as its free acid or
ammonium salt, in or on the following raw agricultural commodities:  Animal feed,nongrass, group, forage - 3.0 ppm; animal feed, nongrass, group, hay - 5.5 ppm; alfalfa,
seed - 0.15 ppm; and alfalfa, seed screenings - 0.15 ppm.  The currently established alfalfa
forage and alfalfa hay tolerances will be removed since they will be covered by the new
nongrass animal feed forage and hay group tolerances.  The tolerance for canola seed will
be established for residues of the parent compound, imazethapyr, only.G/SPS/N/USA/719

Finally, EPA determined that tolerances of 0.10 ppm for imazethapyr and the metabolite 2-
[4,5-dihydro-4-methyl-4-(1-methylethyl)-5- oxo-1H-imidazol-2-yl]-5-(1-hydroxyethyl)-3-
pyridine carboxylic acid need to be established for meat byproducts of cattle, goat, hog,
horse, and sheep;  the registrant did not propose tolerances for these commodities.  EPA
determined that tolerances are not needed for eggs; milk; meat and fat of cattle, goat, hog,
horse, and sheep;  and poultry commodities because there is no reasonable expectation offinite residues based on the calculated maximum total dietary burdens and the results of the
poultry metabolism study.
