vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
viii. Make sure to submit your comments by the comment period
deadline identified.
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 these petitions so that the public has an
opportunity to comment on these requests for the establishment or
modification of regulations for residues of pesticides in or on food
commodities. Further information on the petitions may be obtained
through the petition summaries referenced in this unit.
New Tolerances
1. PP 9E7544. (EPA-HQ-OPP-2009-0289). 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 a
tolerance in 40 CFR part 180 for residues of the insecticide
acetamiprid, N1-[(6-chloro-3-pyridyl)methyl]- N2-cyano-N1-
methylacetamidine, in or on fruit, small, vine climbing, except fuzzy
kiwifruit, subgroup 13-07F at 0.35 parts per million (ppm); and
tolerances with regional restrictions for clover, forage at 0.10 ppm;
clover, hay at 0.01 ppm; and tea at 50 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 has been developed which
involves extraction of acetamiprid from crops with methanol and
analysis by liquid chromatography/mass spectrometry/mass spectrometry
(LC/MS/MS) methods. The limit of quantification (LOQ) and the limit of
detection (LOD) for the method are calculated to be 0.0076 ppm and
0.0025 ppm for clover forage, respectively while the LOQ and the LOD
for the method for clover hay are calculated to be 0.0082 ppm and
0.0027 ppm, respectively. The LOQ and LOD for grape are calculated to
be 0.0064 ppm and 0.0021 ppm, respectively. The LOQ and LOD for
greenhouse-grown tomatoes were 0.0075 ppm and 0.0025, respectively.

2. PP 9E7550. (EPA-HQ-OPP-2009-0943). Bayer CropScience, LP, P.O.
Box 12014, 2 T.W. Alexander Dr., Research Triangle Park, NC 27709-2014,
proposes to establish a tolerance in 40 CFR part 180 for residues of
the insecticide ethiprole; 1 H-pyrazole-3-carbonitrile, 5-amino-1-[2,6-
dichloro-4-(trifluromethyl)phenyl]-4-(ethylsulfinyl), and its sulfones
metabolite (RPA 097973), 5-amino-1-(2,6-dichloro-4-
trifluoromethylphenyl)-4-ethylsulfonylpyrazole-3-carbonitrile,
[[Page 41900]]
expressed as parent equivalent in or on imported tea (dried and
instant) at 50 ppm; imported rice (grain and bran) at 3.0 ppm; meat
(cattle, goat, hog, horse, sheep) at 0.01 ppm; fat (cattle, goat, hog,
horse, sheep) at 0.1 ppm; liver (cattle, goat, hog, horse, sheep) at
0.1 ppm; meat by-products, except liver (cattle, goat, hog, horse,
sheep) at 0.02 ppm; milk at 0,01 ppm; milk, fat at 0.1 ppm; poultry,
meat at 0.01 ppm; poultry, fat at 0.1 ppm; poultry, meat by-products at
0.05 ppm; and eggs at 0.05 ppm. Practical enforcement analytical
methods for detecting and measuring levels of ethiprole and its
sulfones metabolite have been developed and validated in/on all
appropriate plant and animal matrices. For plants, extraction using
acetonitrile/water (9/1, v/v) is followed by LC/MS/MS quantification
Multiple Reaction Monitoring (MRM) mode. The LOQ for enforcement
purposes is 0.002 mg/kg expressed as parent equivalents in the rice
matrices and 0.02 mg/kg in tea. For animals, extraction using 80:20
acetonitrile/deionized water is followed by oxidation with 34 percent
peracetic acid that converts ethiprole to RPA97973, with quantification
by gas chromatography/electron capture detection (GC/ECD). The LOQ for
all animal commodities is 0.01 mg/kg. Contact: Carmen Rodia, (703) 306-

the fungicide fluazinam, 3-chloro-N -[3-chloro-2,6-dinitro-4-
(trifluoromethyl) phenyl]-5-(trifluoromethyl)-2-pyridinamine in or on
carrot, root at 0.8 ppm. An analytical method using gas chromatography
with electron capture detection (GC-ECD) for the determination of
fluazinam residues on carrots has been developed and validated. The
method involves solvent extraction followed by liquid-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 LOQ of
the method is 0.02 ppm in carrot. Contact: Laura Nollen, (703) 305-
7390; nollen.laura@epa.gov.
4. PP 8F7420. (EPA-HQ-OPP-2009-0276). BASF Corporation, P.O. Box
13528, Research Triangle Park, NC 27709-3528, proposes to establish a
tolerance in 40 CFR part 180 for residues of the fungicide
triticonazole in or on cereal grains (except rice), Crop group 15 at
0.05 ppm; cereal grains (except rice), forage, fodder, and hay, Crop
group 16 at 0.10 ppm. The method of analysis included extraction and
LC/MS/MS quantitation. Contact: Bryant Crowe, (703) 305-0025;
crowe.bryant@epa.gov.
5. PP 8F7449. (EPA-HQ-OPP-2008-0814). Syngenta Crop Protection,
Inc., PO Box 18300, Greensboro, NC 27419, proposes to establish a
tolerance in 40 CFR part 180 for residues of the insecticide
thiamethoxam, 3-[(2-chloro-5-thiazolyl)methyl]tetrahydro-5-methyl-N-
nitro-4H-1,3,5-oxadiazin-4-imine (CAS Reg. No. 153719-23-4) and its
metabolite N-(2-chloro-thiazol-5-ylmethyl)-N'-methyl-N'-nitro-guanidine
in or on rice, grain at 0.02 ppm; rice, straw at 0.02 ppm; rice, bran
at 0.02 ppm; rice, polished at 0.02 ppm; and rice, hulls at 0.1 ppm.
Syngenta Crop Protection, Inc. has submitted practical analytical
methodology for detecting and measuring levels of thiamethoxam in or on
raw agricultural commodities. This method is based on crop specific
cleanup procedures and determination by liquid chromatography with
either ultraviolet (UV) or mass spectrometry (MS) detections. The LOD
for each analyte of this method is 1.25 nanograms (ng) injected for
samples analyzed by UV and 0.25 ng injected for samples analyzed by MS,
and the LOQ is 0.005 ppm for milk and juices, and 0.01 ppm for all
other substrates. Contact: Julie Chao, (703) 308-8735;
chao.julie@epa.gov.
6. PP 8F7485. (EPA-HQ-OPP-2009-0279). Bayer CropScience, P.O. Box
12014, 2 T.W. Alexander Drive, Research Triangle Park, NC 27709,
proposes to establish a tolerance in 40 CFR part 180 for residues of
the fungicide prothioconazole and prothioconazole-desthio in or on
grain, cereal, group 15, except sweet corn, sorghum, and rice at 0.35
ppm; forage, cereal, group 16, except sweet corn, sorghum, and rice at
8.0 ppm; stover, cereal, group 16, except sweet corn, sorghum, and rice
at 10 ppm; hay, cereal, group 16, except sweet corn, sorghum, and rice
at 7.0 ppm; straw, cereal, group 16, except sweet corn, sorghum, and
rice at 5.0 ppm; corn, sweet, forage at 7 ppm; corn, sweet, stover at 8
ppm; and corn, sweet, kernel plus cob with husks removed at 0.02 ppm.
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 analytical 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:

7. PP 9F7529. (EPA-HQ-OPP-2009-0268). BASF Corporation, Research
Triangle Park, NC 27709, proposes to establish a tolerance in 40 CFR
part 180 for residues of the fungicide boscalid (BAS 510F); [3-
pyridinecarboxamide, 2-chloro-N-(4'-chloro(1,1'-biphenyl)-2-yl)-] in or
on alfalfa, forage at 35 ppm; alfalfa, hay at 85 ppm; and citrus, Crop
group 10 at 2 ppm. In plants, the parent residue is extracted using an
aqueous organic solvent mixture followed by liquid/liquid partitioning
and a column clean up. Quantitation is by gas chromatography using gas
chromatography/mass spectrometry (GC/MS). In livestock the residues are
extracted with methanol. The extract is treated with enzymes in order
to release the conjugated glucuronic acid metabolite. The residues are
then isolated by liquid/liquid partition followed by column
chromatography. The hydroxylated metabolite is acetylated followed by a
column clean-up. The parent and acetylated metabolite are quantitated
by GC with electron capture detection (GC/ECD). Contact: Bryant Crowe,
(703) 305-0025; crowe.bryant@epa.gov.
8. PP 9F7549. (EPA-HQ-OPP-2009-0325). Gowan Company, 370 South
Main St., Yuma, AZ 85364, proposes to establish tolerances in 40 CFR
part 180 for residues of the insecticide hexythiazox, trans-5-(4-
chlorophenyl)-N-cyclohexyl-4-methyl-2-oxothiazolidine-3-carboxamide and
its metabolites containing the (4-chlorophenyl)-4-methyl-2-oxo-3-
thiazolidine moiety in or on corn, sweet kernel plus cob with husk
removed at 0.1 ppm; corn, sweet, forage at 3 ppm; beans, dried at 0.4
ppm; and beans, succulent at 0.4 ppm. These proposed tolerances are
geographically limited to Western regions of the United States. A
practical analytical method, high pressure liquid chromatography with
an ultraviolet detector, which detects and measures residues of
hexythiazox and its metabolites as a common moiety, is available for
enforcement purposes with a limit of detection that allows
[[Page 41901]]
monitoring of food with residues at or above the levels set in these
tolerances. Contact: Olga Odiott, (703) 308-9369; odiott.olga@epa.gov.
