1. PP 8E7433. (EPA-HQ-OPP-2009-0013). The Interregional Research Project Number 4 (IR-4), IR-4 Project Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, proposes to establish tolerances in 40 CFR 180.603 for the combined residues of the insecticide dinotefuran, (RS)-1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine and its major metabolites DN, 1-methyl-3-(tetrahydro-3-furylmethyl)guanidine, and UF, 1-methyl-3-(tetrahydro-3-furylmethyl)-urea in or on brassica, leafy greens, subgroup 5B at 17.0 parts per million (ppm) and turnip, greens at 17.0 ppm. The IR-4 submitted this petition on behalf of the registrants, Valent USA Corporation and Mitsui Corporation, Minato-ku, Tokyo, Japan. Mitsui Chemicals, Inc., has submitted practical analytical methodology for detecting and measuring levels of dinotefuran and its metabolites, UF and DN, in or on raw agricultural commodities. The high performance liquid chromatography (HPLC) method was validated for determination of dinotefuran, DN and UF in or on tomatoes and peppers, cucurbits, brassica, grapes, potatoes, and lettuce for raw agricultural commodity matrices and in or on tomato paste and puree, grape juice and raisins and potato chips, granules, and wet peel for processed commodity matrices. After extraction with a water/acetonitrile mixture and clean up with hexane and extraction columns, concentrations of dinotefuran and its metabolites were quantified after HPLC separation by tandem mass spectrometry (MS/MS) detection. The limit of quantitation was 0.01 ppm for all matrices. Contact: Sidney Jackson, (703) 305-7610, jackson.sidney@epa.gov.

2. PP 8E7474. (EPA-HQ-OPP-2009-0076). IR-4, IR-4 Project Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, proposes to increase the tolerances in 40 CFR 180.507 for residues of the fungicide azoxystrobin: (methyl (E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate) and the Z isomer of azoxystrobin,(methyl (Z)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]pheny1}-3-methoxyacrylate) in or on barley, grain from 0.1 ppm to 3.0 ppm and barley, straw from 4.0 ppm to 7.0 ppm. An adequate analytical method, gas chromatography with nitrogen-phosphorus detection (GC-NPD) or in mobile phase by high performance liquid chromatography with ultra-violet detection (HPLC-UV), is available for enforcement purposes with a limit of detection that allows monitoring of food with residues at or above the levels set in these tolerances. The EPA concluded that the methods are adequate for enforcement. Analytical methods are also available for analyzing meat, milk, poultry and eggs which also underwent successful independent laboratory validations.

1. PP 8E7477. (EPA-HQ-OPP-2009-0165). Huntsman Corporation, 10003 Woodloch Forest Dr., The Woodlands, TX 77380, proposes to establish an exemption from the requirement of a tolerance in 40 CFR 180.920 for residues of tallowamine, ethoxylated, mixture of dihydrogen phosphate monohydrogen phosphate esters and the corresponding ammonium, calcium, potassium, and sodium salts of the phosphate esters, where the poly(oxyethylene) content averages 2-20 moles (CAS Reg. No. 68308-48-5) when used as a pesticide inert ingredient in pesticide formulations in or on all raw agricultural commodities. Because this petition is a request for an exemption from the requirement of a tolerance, no analytical method is required. Contact: Alganesh Debesai, (703) 308-8353, debesai.alganesh@epa.gov.
2. PP 8E7490. (EPA-HQ-OPP-2009-0047). Rohm and Haas Chemicals LLC, 100 Independence Mall West, Philadelphia, PA 19106-2399, proposes to establish an exemption from the requirement of a tolerance in 40 CFR Start Printed Page 15976180.960 for residues of 2-propenoic acid, butyl ester polymer with ethyl 2-propenoate and N-(hydroxymethyl)-2-propenamide (CAS Reg. No. 33438-19-6) when used as a pesticide inert ingredient in pesticide formulations in or on raw agricultural commodities. Because this petition is a request for an exemption from the requirement of a tolerance, no analytical method is required. Contact: Karen Samek, (703) 347-8825, samek.karen@epa.gov.
3. PP 8E7504. (EPA-HQ-OPP-2009-0138). Dow AgroSciences, LLC, 9330 Zionsville Rd., Indianapolis, IN, 46268, proposes to establish an exemption from the requirement of a tolerance for residues of 2-Propanol, 1,1',1”-nitrilotris-(TIPA) (CAS Reg. No. 122-20-3) under 40 CFR 180.910 when used as a pesticide inert ingredient for use as a neutralizer in pesticide formulations. Because this petition is a request for an exemption from the requirement of a tolerance, no analytical method is required. Contact: Lisa Austin, (703) 305-7894, austin.lisa@epa.gov.
