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, [phone], [e-mail].

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, [phone], [e-mail].

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.
