1. PP 0E7794. (EPA-HQ-OPP-2011-0110). BASF Corporation, 26 Davis Drive, Research Triangle Park, NC 27709, proposes to establish a tolerance in 40 CFR part 180 for residues of the herbicide imazapic, (±)-2-[4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1-H-imidazol-2-yl]-5-methyl-3-pyridinecarboxylic acid, in or on soybean at 0.5 parts per million (ppm). The proposed analytical method for detecting residues of imazapic and the metabolites M715H001 (CL 263,284) and M715H002 (CL 189,215) in soybean seed and processed fractions is a liquid chromatography-tandem mass spectrometry (LC/MS/MS) method. Enforcement methods for analysis of residues of imazapic and metabolite M715H001 (CL 263,284) in animal commodities have been previously submitted. The analytical method for analysis in meat and meat byproducts is based on capillary electrophoreses with confirmation by LC/MS. The analytical method for analysis in milk and fat is based on determination by LC/MS with confirmation by LC/MS/MS. Contact: Mindy Ondish, (703) 605-0723, e-mail address: ondish.mindy@epa.gov.
2. PP 0E7797. (EPA-HQ-OPP-2011-0146). Bayer CropScience, 2 T. W. Alexander Drive, Research Triangle Park, NC 27709, proposes to establish import tolerances in 40 CFR part 180 for residues of the fungicide propineb, [[[2-[(Dithiocarboxy)amino]-1-methyethyl] carbamodithioato(2-)-êS,êS']zinc], in or on apple, fruit at 2.5 ppm; apple, wet pomace at 2.5 ppm; pear, fruit at 2.5 ppm; citrus, fruit at 4.5 ppm; banana, fruit (bagged) at 1.2 ppm; banana, fruit (unbagged) at 8.0 ppm; vegetable, cucurbit, group 9 at 8.0 ppm; vegetables, fruiting, group 8 at 8.0 ppm; onion, dry bulb at 1.6 ppm; onion, green at 13 ppm; grape at 0.8 ppm; olive at 0.35 ppm; avocado; and fruit crops, including: Black sapote; canistel; mamey sapote; mango; papaya; sapodilla; and star apple at 5.0 ppm. Propineb is rapidly degraded by hydrolysis and photolysis to the main metabolite propylenethiourea (PTU), which is the toxicologically relevant metabolite. Various analytical methods have been used, but samples are now prepared and analyzed by high performance liquid chromatography (HPLC)-atmosphere pressure chemical ionization/MS/MS. The limits of quantitation LOQ) is 0.01 ppm for PTU. Contact: Tamue L. Gibson, (703) 305-9096, e-mail address: gibson.tamue@epa.gov.
3. PP 0E7820. (EPA-HQ-OPP-2011-0087). Interregional Research Project Number 4 (IR-4), 500 College Road East, Suite 201 W., Princeton, NJ 08540, proposes to establish tolerances in 40 CFR part 180 for residues of the insecticide spirodiclofen, 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4,5]dec-3-en-4-yl 2,2-dimethylbutanoate, in or on sugar apple, cherimoya, atemoya, custard apple, ilama, soursop, biriba, guava, feijoa, jaboticaba, wax jambu, starfruit, passionfruit, persimmon and acerola at 0.45 ppm; and lychee, longan, Spanish lime, rambutan and pulasan at 3.5 ppm. Adequate analytical methodology using LC/MS/MS detection is available for enforcement purposes. Contact: Laura E. Nollen, (703) 305-7390, e-mail address: nollen.laura@epa.gov.
4. PPs0F7714 and F7715. (EPA-HQ-OPP-2011-0053). Bayer CropScience, P.O. Box 12014, 2 T.W. Alexander Drive, Research Triangle Park, NC 27709, proposes to establish tolerances in 40 CFR part 180 for residues of the fungicide prothioconazole, 2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl-2-hydroxypropyl)]-1,2-dihydro-3H-1,2,4-triazole-3-thione and its desthio metabolite, in or on raw or processed agricultural commodities rice, grain at 0.25 ppm; rice, hulls at 1.0 ppm; alfalfa, forage and alfalfa, hay at 0.02 ppm; and potato, tuber at 0.02 ppm. Bayer CropScience is also proposing use of the currently established tolerances for residues of prothioconazole, 2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl-2-hydroxypropyl)]-1,2-dihydro-3H-1,2,4-triazole-3-thione and its desthio metabolite, in or on the raw agricultural commodity pea and bean, dried shelled, except soybean, subgroup 6C; soybean, forage; soybean, hay; and soybean, seed to support the use of prothioconazole as a seed treatment on these crops. Bayer CropScience is also proposing that the above proposed tolerances on rice, based on foliar data, also support the use of prothioconazole as a seed treatment on rice. The analytical method for determining residues of concern in plants extracts residues of prothioconazole and JAU6476-desthio and converts the prothioconazole to JAU6476-desthio and JAU6476-sulfonic acid. Following addition of internal standards the sample extracts are analyzed by LC/MS/MS. Radiovalidation and independent laboratory validation have shown that the method adequately quantifies prothioconazole residues in treated commodities. The validated LOQ for total prothioconazole-derived residues in rice grain was 0.02 ppm. The validated LOQs were 0.01 ppm for 1H-1,2,4-triazole and 0.05 ppm for the triazole conjugates for grain. The Start Printed Page 17376analytical method for analysis of large animal tissues includes extraction of the residues of concern, followed by addition of an internal standard to the extract. The extract is then hydrolyzed to release conjugates, partitioned and analyzed by LC/MS/MS as prothioconazole, JAU6476-desthio and JAU6476-4-hydroxy. The method for analysis of milk eliminated the initial extraction step in the tissue method. Contact: Tawanda Maignan, (703) 308-8050, e-mail address: maignan.tawanda@epa.gov.
5. PP 0F7812. (EPA-HQ-OPP-2011-0007). 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 acetamiprid, N 1-[(6-chloro-3-pyridyl)methyl]-N 2-cyano-N 1-methylacetamidine, including its metabolites and degradates, in or on food/feed handling establishments at 0.05 ppm. Based upon the metabolism of acetamiprid in plants and the toxicology of the parent and metabolites, quantification of the parent acetamiprid is sufficient to determine toxic residues. As a result a method was developed that involves extraction of acetamiprid from composite meals with a solvent followed by a decantation and filtration and finally analysis by a LC/MS/MS method. The LOQ and the limit of detection (LOD) for the method are calculated to be 0.05 ppm and 0.01 ppm for composite meals, respectively. The method was reliable for composite meal analyses with an overall average recovery of 93 ± 14%. Contact: Jennifer Urbanski, (703) 347-0156, e-mail address: urbanski.jennifer@epa.gov.
6. PP 0F7817. (EPA-HQ-OPP-2011-0144). E.I. duPont de Nemours and Company, 1007 Market Street, Wilmington, DE 19898, proposes to establish a tolerance in 40 CFR part 180 for residues of the herbicide aminocyclopyrachlor, [6-amino-5-chloro-2-cyclopropyl-4-pyrimidinecarboxylic acid] and aminocyclopyrachlor methyl ester [methyl 6-amino-5-chloro-2-cyclopropyl-4-pyrimidinecarboxylate], expressed as aminocyclopyrachlor, in or on grass forage at 65 ppm; grass hay at 125 ppm; fat (of cattle, goat, horse and sheep) at 0.07 ppm; meat (of cattle, goat, horse and sheep) at 0.02 ppm; meat byproducts—excluding liver (of cattle, goat, horse and sheep) at 0.4 ppm; liver (of cattle, goat, horse and sheep) at 0.06 ppm; and milk at 0.035 ppm. Adequate analytical methods for enforcement purposes are available to monitor residues of aminocyclopyrachlor in grass commodities, milk, meat and meat byproducts. The analytical methods for both grass commodities and ruminant commodities use an LC/MS/MS system operating with an electrospray interface (ESI) in positive ion mode with limits of quantitation (LOQ) of 0.01 ppm. Both methods have been successfully independently validated by outside laboratories. Aminocyclopyrachlor had also been tested through the Food and Drug Administration (FDA), Multi-residue Methodology. Contact: Mindy Ondish, (703) 605-0723, e-mail address: ondish.mindy@epa.gov.
7. PP 1F7822. (EPA-HQ-OPP-2011-0152). E.I. du Pont de Nemours and Company, 1007 Market Street, Wilmington, DE 19898, proposes to establish tolerances in 40 CFR part 180 for residues of the herbicide quizalofop-p-ethyl, (ethyl-2-[4-(6-chloroquinoxalin-2-yl oxy) phenoxy] propanoate), including its metabolites and degradates (DUPONTTM ASSURE® II), in or on corn, grain at 0.01 ppm; corn, forage at 0.01 ppm; and corn, stover at 0.03 ppm. The currently proposed aspirated grain fraction (AGF) tolerance of 1.0 ppm, based on sorghum AGF in PP 0E7802, will not be changed by corn AGF residues. An adequate analytical methodology (HPLC using either ultraviolet (UV) or fluorescence detection) is available for enforcement purposes in Volume II of the Food and Drug Administration Pesticide Analytical Method (PAM II, Method I). Contact: Mindy Ondish, (703) 605-0723, e-mail address: ondish.mindy@epa.gov.
1. PP 0E7781. (EPA-HQ-OPP-2010-0980). BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 27709, proposes to amend the tolerances in 40 CFR 180.560 by amending the tolerance expression to establish combined residues of cloquintocet-mexyl (acetic acid, [(5-chloro-8-quinolinyl)oxy]-,1-methylhexylester) (CAS Reg. No. 99607-70-2) and its acid metabolite (5-chloro-8-quinlinoxyacetic acid) when used as an inert ingredient (safener) in pesticide formulations containing either the herbicide clodinafop-propargyl or pinoxaden in a 1:4 ratio of safener to active ingredient or in combination with the registered active ingredient dicamba, in or on wheat, grain at 0.10 ppm; wheat, forage at 0.2 ppm; wheat, hay at 0.50 ppm; and wheat, straw at 0.10 ppm.

1. PP 0E7815. (EPA-HQ-OPP-2011-0093). Monsanto Company, 1300 I Street NW., Suite 450 East, Washington, DC 20005, proposes to establish an exemption from the requirement of a tolerance for residues of amides, C5-C9, N-3-[(dimethylamino)propyl] (CAS No. 1044764-00-2) and amides C6-C12, N-3-[(dimethylamino)propyl] (CAS No. 1044754-06-8) when used as a pesticide inert ingredient (surfactant) in pesticide formulations in 40 CFR part 180.910 pre- and post-harvest uses. The petitioner believes no analytical method is needed because they are not applicable or required for the establishment of a tolerance exemption for inert ingredients. Contact: Deirdre Sunderland, (703) 603-0851, e-mail address: sunderland.deirdre@epa.gov.
2. PP 0E7797. (EPA-HQ-OPP-2011-0146). Bayer CropScience, 2 T.W. Alexander Drive, Research Triangle Park, NC 27709, proposes to establish an exemption from the requirement of a tolerance for residues of the fungicide propineb, [[[2-[(Dithiocarboxy)amino]-1-methyethyl] carbamodithioato(2-)-êS, êS']zinc], in or on apple, juice; citrus, juice; citrus, oil; citrus, dried pulp; tomato, puree; tomato, paste. The petitioner believes no analytical method is needed because no concentration was recovered by the maximum residue level (MRL) for these raw agricultural commodities. Also, the high performance liquid chromatography-atmosphere pressure chemical ionization/tandem mass spectrometry analytical method is available to EPA for the detection and measurement of the pesticide residues.
