    3. Environmental justice. EPA seeks to achieve environmental 
justice, the fair treatment and meaningful involvement of any group, 
including minority and/or low-income populations, in the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies. To help address potential environmental justice issues, the 
Agency seeks information on any groups or segments of the population 
who, as a result of their location, cultural practices, or other 
factors, may have atypical or disproportionately high and adverse human 
health impacts or environmental effects from exposure to the pesticides 
discussed in this document, compared to the general population.

II. What Action is the Agency Taking?

     EPA is announcing its receipt of several pesticide petitions filed 
under section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 
21 U.S.C. 346a, proposing the establishment or modification of 
regulations in 40 CFR part 174 or part 180 for residues of pesticide 
chemicals in or on various food commodities. EPA has determined that 
the pesticide petitions described in this notice contain the data or 
information prescribed in FFDCA section 408(d)(2); however, EPA has not 
fully evaluated the sufficiency of the submitted data at this time or 
whether the data support granting of the pesticide petitions. 
Additional data may be needed before EPA can make a final determination 
on these pesticide petitions.
     Pursuant to 40 CFR 180.7(f), a summary of each of the petitions 
that are the subject of this notice, prepared by the petitioner, is 
included in a docket EPA has created for each rulemaking. The docket 
for each of the petitions is available on-line at http://
www.regulations.gov.
    As specified in FFDCA section 408(d)(3), (21 U.S.C. 346a(d)(3)), 
EPA is publishing notice of the petition so that the public has an 
opportunity to comment on this request for the establishment or 
modification of regulations for residues of pesticides in or on food 
commodities. Further information on the petition may be obtained 
through the petition summary referenced in this unit.

New Tolerances

     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 8E7447. (EPA-HQ-OPP-2009-0012). IR-4, IR-4 Project 
Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, 
proposes to establish tolerances in 40 CFR 180.544 for residues of the 
insecticide methoxyfenozide and its metabolites RH-117,236 free phenol 
of methoxyfenozide; 3,5-dimethylbenzoic acid N-tert-butyl-N'-(3-
hydroxy-2-methylbenzoyl) hydrazide, RH-151,055 glucose conjugate of RH-
117,236; 3,5-dimethylbenzoic acid N-tert-butyl-N-[3( -[beta]-D-
glucopyranosyloxy)-2-methylbenzoyl]-hydrazide) and RH-152,072 the 
malonylglycosyl conjugate of RH-117,236 in or on fruit, citrus, group 
10 at 2.0 ppm and citrus oil at 70 ppm for tolerances with regional 
registrations; and pea and bean, dried shelled, except soybean, 
subgroup 6C at 0.35 ppm; pomegranate at 0.6 ppm; corn, pop, grain at 
0.05 ppm; corn, pop, stover at 125 ppm; and corn, pop, forage at 30 
ppm. Adequate enforcement methods are available for determination of 
methoxyfenozide residues in plant commodities, as derived from Dow 
AgroSciences GRM 02.25, ``Determination of Residues of Methoxyfenozide 
in High Moisture Crops by Liquid Chromatography with Tandem Mass 
Spectrometry Detection'' which has been validated. This method is based 
on enforcement method TR 34-00-28 developed by Rohm and Haas which has 
been extensively validated, including an independent laboratory 
validation. It was judged to be adequate to enforce tolerances for 
indirect or inadvertent residues of methoxyfenozide and relevant 
metabolites in/on high and low moisture rotational crops. Contact:

13528, Research Triangle Park, NC 27709, proposes to establish an 
import tolerance in 40 CFR 180.517 for residues of the insecticide 
mixture comprising fipronil (5-amino-1[2,6-dichloro-4-
(trifluoromethyl)phenyl]-4-[(1R,S)-trifluoromethyl)sulfinyl]-1H-
pyrazole-3-carbonitrile) and its metabolites 5-amino-1-[2,6-dichloro-4-
(trifluoromethyl)phenyl]-4-[(trifluoromethyl)sulfonyl]-1H-pyrazole-3-
carbonitrile and 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl-4-
[(trifluoromethyl)thio]-H-pyrazole-3-carbonitrile and its 
photodegradate 5-amino-1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-
[(1R,S)-(trifluoromethyl)-1H-pyrazole-3-carbonitrile] in or on rice, 
grain at 0.04 ppm. Validated analytical methods are available for 
detecting and measuring levels of fipronil and its metabolites in rice. 
The method utilizes capillary gas chromatography equipped with a Ni 
electron capture detector. Alternatively, a liquid chromatography with 
tandem mass spectrometry (LC/MS/MS) detector

[[Page 15973]]

may be used. The limit of quantitation for rice is 0.01 ppm for all 
analytes. The limit of detection is 0.003 ppm for all analytes.

     4. PP 8E7481. (EPA-HQ-OPP-2009-0092). IR-4, IR-4 Project 
Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, 
proposes to establish tolerances in 40 CFR 180.431(a) for the combined 
residues of the herbicide clopyralid, (3,6-dichloro-2-
pyridinecarboxylic acid) in or on swiss chard at 5.0 ppm and bushberry 
subgroup 13-07B at 6.0 ppm; and to establish a tolerance in 40 CFR 
180.431(c) with regional restrictions for residues of clopyralid in or 
on strawberry, annual at 4.0 ppm. An adequate residue analytical method 
is available for enforcement of the tolerances. This method determines 
clopyralid as the methyl ester by gas chromatography using electron 
capture detection. This method has been successfully validated by the 
EPA and has been published in FDA's Pesticide Analytical Manual, Volume 
II (PAM II). Contact: Laura Nollen, (703) 305-7390, 
nollen.laura@epa.gov.
     5. PP 8E7492. (EPA-HQ-OPP-2009-0018). IR-4, IR-4 Project 
Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, 
proposes to establish tolerances in 40 CFR 180.510 for residues of the 
insecticide pyriproxyfen in or on vegetable, leaves of root and tuber, 
group 2 at 2.0 ppm; vegetable, leafy, except brassica, group 4 at 3.0 
ppm; vegetable, foliage of legume, group 7 at 2.0 ppm; artichoke, globe 
at 2.0 ppm; asparagus at 2.0 ppm; watercress at 2.0 ppm; and small 
fruit vine climbing subgroup, except grape 13-07E at 0.35 ppm. 
Practical analytical methods for detecting and measuring levels of 
pyriproxyfen (and relevant metabolites) have been developed and 
validated in/on all appropriate agricultural commodities, respective 
processing fractions, milk, animal tissues, and environmental samples. 
The extraction methodology has been validated using aged radiochemical 
residue samples from metabolism studies. The methods have been 
validated in cottonseed, apples, soil, and oranges at independent 
laboratories. The EPA has successfully validated the analytical methods 
for analysis of cottonseed, pome fruit, nutmeats, almond hulls, and 
fruiting vegetables. The limit of detection of pyriproxyfen in the 
methods is 0.01 ppm which will allow monitoring of food with residues 
at the levels proposed for the tolerances. Contact: Susan Stanton, 
(703) 305-5218, stanton.susan@epa.gov.
     6. PP 8E7506. (EPA-HQ-OPP-2009-0032). IR-4, IR-4 Project 
Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, 
proposes to establish tolerances in 40 CFR 180.574 for residues of the 
fungicide fluazinam (3-chloro-N-[3-chloro-2,6-dinitro-4-
(trifluoromethyl) phenyl]-5-(trifluoromethyl)-2-pyridinamine) in or on 
lettuce, head at 0.02 ppm; lettuce, leaf at 2.0 ppm; onion, bulb, 
subgroup 3-07A at 0.15 ppm; and bushberry subgroup 13-07B at 4.5 ppm.

detection (GC-ECD) for the determination of fluazinam residues on 
blueberry, lettuce and onion has been developed and validated. The 
method involves solvent extraction followed by liquid partitioning and 
concentration prior to a final purification using column 
chromatography. The method has been successfully validated by an 
independent laboratory using peanut nutmeat as the matrix. The limit of 
quantitation (LOQ) of the method is 0.01 ppm in lettuce and onion, and 
0.02 in blueberry. An analytical method using reversed-phase HPLC with 
ultraviolet (UV) absorbance detection for the determination of AMGT 
residues on blueberry has been developed and validated. The limit of 
quantitation of the method for AMGT is 0.04 ppm in/on blueberry.

proposes to establish a tolerance in 40 CFR part 180 for residues of 
the fungicide trifloxystrobin (Benzeneacetic acid, (E,E)-
(methoxyimino)-2-[[[[1-[3-(trifluoromethyl) 
phenyl]ethylidene]amino]oxy]methyl]-methyl ester) and the free form of 
its acid metabolite CGA-321113 ((E,E)-methoxyimino-[2-[1-(3-
trifluoromethyl-phenyl)-ethylideneaminooxymethyl]-phenyl]acetic acid), 
in or on vegetable, tuberous and corm, subgroup 1C at 0.04 ppm; 
artichoke, globe at 1 ppm; leafy greens, subgroup 4A at 15 ppm; leafy 
petioles, group 4B at 7 ppm; brassica, head and stem, subgroup 5A at 
1.1 ppm; brassica, leafy greens, subgroup 5B at 12 ppm; fruit, small 
fruit vine climbing, subgroup 13-07F, except fuzzy kiwifruit at 2 ppm; 
berry, lowgrowing, subgroup 13-07G at 1.1 ppm; herb, subgroup 19A at 
120 ppm; and spice, subgroup 19B, except black pepper at 50 ppm. A 
practical analytical methodology for detecting and measuring levels of 
trifloxystrobin in or on raw agricultural commodities has been 
submitted. The LOD for each analyte of this method is 0.08 ng injected, 
and the LOQ is 0.02 ppm. The method is based on crop specific cleanup 
procedures and determination by gas chromatography with nitrogen-
phosphorus detection. A newer analytical method is available employing 
identical solvent mixtures and solvent to matrix ratio (as the first 
method), deuterated internal standards, and LC/MS-MS with an 
electrospray interface, operated in the positive ion mode. The LOD for 
trifloxystrobin range from 0.002 ppm to 0.01 ppm, depending on the 
crops, and the LOQ is 0.01 ppm. Contact: Rosemary Kearns, (703) 305-

P.O. Box 18300, Greensboro, NC 27419, proposes to establish a tolerance 
in 40 CFR part 180 for residues of the fungicide difenoconazole, (1-[2-
[2-chloro-4-(4-chlorophenoxy)phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl]-
1H-1,2,4-triazole) in or on almond, hulls at 7 ppm; brassica, head and 
stem, subgroup 5A at 1.9 ppm; brassica, leafy green, subgroup 5B at 30 
ppm; citrus, dried pulp at 2.5 ppm; citrus, oil at 28 ppm; grape at 4 
ppm; grape, raisin at 14 ppm; nut, tree, group 14 at 0.03 ppm; onion, 
bulb, subgroup 3-07A at 6 ppm; onion, green, subgroup 3-07B at 0.15 
ppm; pistachio at 0.03 ppm; and vegetables, cucurbit, group 9 at 0.7 
ppm. Syngenta Crop Protection, Inc. has submitted a practical 
analytical method (AG-575B) for detecting and measuring levels of 
difenoconazole in or on food with a LOQ that allows monitoring of food 
with residues at or above the levels set in the proposed tolerances. 
The EPA has validated this method and copies have been provided to the 
FDA for insertion into the pesticide analytical manual (PAM) II. Method 
REM 147.08 is also available as an enforcement method, for the 
determination of residues of difenoconazole in crops. Residues are 
quantified by LC/MS/MS. Contact: Rosemary Kearns, (703) 305-5611,

     16. PP 8F7488. (EPA-HQ-OPP-2009-0029). 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

[[Page 15975]]

of 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.

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-

     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,

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.
