Nippon Soda Co., Ltd., c/o Nisso America, Inc., 45 Broadway, Suite 2120, New York, NY 10006, proposes to establish a tolerance in 40 CFR part 180 for residues of the insecticide cyflufenamid, in or on cucurbit crop group at 0.05 ppm; pome fruit crop group at 0.05 ppm; apple, wet pomace at 0.1 ppm; grape (and other small climbing vine fruit (except fuzzy kiwifruit)) crop group at 0.015 ppm; raisin at 0.3 ppm; and strawberry (and other low growing berries) crop group at 0.2 ppm. Based upon the metabolism of cyflufenamid in plants (i.e., parent cyflufenamid as the major residue) and the toxicology of the parent compound, quantification of the parent cyflufenamid is sufficient to determine toxic residues. As a result, a method was developed using solvent extraction Start Printed Page 15975of cyflufenamid from crops and analyzing sample extracts by LC/MS/MS. The LOQ for the method was calculated to be 0.01 ppm. Contact: Samantha Hulkower, (703) 603-0683, hulkower.samantha@epa.gov.

17. PP 8F7501. (EPA-HQ-OPP-2009-0057). E. I. DuPont de Nemours and Company, DuPont Crop Protection, P.O. Box 80038, Wilmington, DE 19880-0038, proposes to establish tolerances in 40 CFR part 180 for residues of the herbicide nicosulfuron, 3-pyridinecarboxamide, 2-((((4,6-dimethoxypyrimidin-2-yl)aminocarbonyl) aminosulfonyl))-N,N-dimethyl in or on grass, forage at 9.0 ppm; grass, hay at 25.0 ppm; fat (of cattle, goat, hog, horse, and sheep) at 0.05 ppm; meat (of cattle, goat, hog, horse, and sheep) at 0.05 ppm; meat byproducts (of cattle, goat, hog, horse, and sheep) at 0.05 ppm; milk at 0.05 ppm; and milk, fat at 0.02 ppm. Adequate analytical methodology, high-pressure liquid chromatography with ESI-MS/MS detection, is available for enforcement purposes. The two methods are “Analytical Method for the Determination of Nicosulfuron (DPX-V9360) and its metabolite IN-V9367 in pasture grass by (high performance liquid chromatography/electrospray interface-tandem mass spectrometry) HPLC/ESI-MS/MS”, DuPont Report 17928 and “Analytical Method for the Determination of Nicosulfuron (DPX-V9360) and its metabolite IN-V9367 in animal tissues by HPLC/ESI-MS/MS”, DuPont Report 17927. The limit of quantitation for nicosulfuron with these methods, in raw agricultural commodities and in processed fractions, is 0.01 ppm. Contact: Mindy Ondish, (703) 605-0723, ondish.mindy@epa.gov.

18. PP 9F7520. (EPA-HQ-OPP-2008-0556). Nichino America, Inc., 4550 New Linden Hill Road, Suite 501, Wilmington, DE 19808, proposes to establish a tolerance in 40 CFR 180.566 for residues of the insecticide fenpyroximate and its z-isomer in or on low-growing berries, subgroup 13-07G at 1.0 ppm. Based upon the metabolism of fenpyroximate in plants and the toxicology of the parent and metabolites, quantification of the parent, fenpyroximate and the z-isomer, combined as fenpyroximate is sufficient to determine toxic residue in plants. As a result an enforcement method has been developed which involves extraction of fenpyroximate from crops with acetone, filtration, partitioning and cleanup, and analysis by gas chromatography using a nitrogen/phosphorous detector. The method has undergone independent laboratory validation. Contact: Melody Banks, (703) 305-5413, banks.melody@epa.gov.

19. PP 9F7523. (EPA-HQ-OPP-2009-0134). IR-4, IR-4 Project Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, proposes to establish a tolerance in 40 CFR 180.439 for residues of the herbicide thifensulfuron methyl (methyl-3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) amino] carbonyl] amino] sulfonyl]-2-thiophenecarboxylate), in or on safflower, seed at 0.05 ppm. Samples were analyzed for residues of thifensulfuron-methyl using liquid chromatography (LC). The lowest level of method validation (LLMV) for each matrix in this study, i.e., safflower seed, meal and oil, was 0.05 ppm of thifensulfuron-methyl. The LOQ for the method for safflower seed was 0.027 ppm of thifensulfuron-methyl. The estimated LOQ for meal and oil were calculated at 0.039 ppm, and 0.0068 ppm of thifensulfuron-methyl, respectively. The LOD for the method for safflower seed was 0.0090 ppm of thifensulfuron-methyl. The estimated LOD for meal and oil were 0.013 ppm, and 0.0023 ppm of thifensulfuron-methyl, respectively.
