summary of interest.
B. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as
CBI and then identify electronically within the disk or CD-ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
2. Tips for preparing your comments. When submitting comments,
remember to:
i. Identify the document by docket ID number and other identifying
information (subject heading, Federal Register date and page number).
ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information
and/or data that you used.
v. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
vi. Provide specific examples to illustrate your concerns and
suggest alternatives.
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 a typical 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. PPs 2E6426 and 9E7625. (EPA-HQ-OPP-2009-0843). The Interregional
Research Project No. 4 (IR-4), 500 College Road East, Suite 201W,
Princeton, NJ 08540, proposes to establish a tolerance in 40 CFR part
180 for residues of the herbicide linuron, (3-(3,4-dichlorophenyl)-1-
methoxy-1-methylurea), and its metabolites convertible to 3,4-
dichloroaniline, calculated as linuron, in or on pea, dry at 0.07 parts
per million (ppm); parsley, leaves at 2.5 ppm; and parsley, dried
leaves at 7.0 ppm for PP 9E7625; and horseradish at 0.050 ppm for PP
2E6426. Adequate enforcement methods are available for the
determination of linuron in plant and animal commodities. The Pesticide
Analytical Manual (PAM) Vol. II, lists a colorimetric method (Method I,
Bleidner et. al.,) and a paper chromatographic method (Method II).
Residues of diuron may interfere in Method I. A modified version of
Method I, which includes a cellulose column step to separate linuron
from diuron, is currently the preferred method for the enforcement of
tolerances. Both of these methods determine linuron and all metabolites
hydrolyzable to 3,4-dichloroaniline and have limits of detection of
0.05 ppm. Contact: Laura Nollen, (703) 305-7390; [email protected].
2. PP 9E7573. (EPA-HQ-OPP-2009-0823). Syngenta Crop Protection,
Inc., 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 mango at 0.09 parts
per million (ppm) and waxapple at 1.5 ppm. The practical analytical
method (AG-575B) was submitted for detecting and measuring levels of
difenoconazole in or on food with a limit of quantification (LOQ) that
allows monitoring of food with residues at or above the levels set in
the proposed tolerances. Method REM 147.08 is also available for
enforcement method, for the determination of residues of difenoconazole
in crops. Residues are qualified by liquid chromatography/mass
spectrometry/mass spectrometry (LC/MS/MS). Contact: Rosemary Kearns,
(703) 305-5611; [email protected].

3. PP 9E7577. (EPA-HQ-OPP-2009-0797). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, in cooperation with Canyon Group LLC., c/o Gowan Company, 370
South Main St., Yuma, AZ 85364, proposes to establish a tolerance in 40
CFR part 180 for residues of the herbicide halosulfuron-methyl, methyl
3-chloro-5-[[[[(4,6-dimethoxy-2-
pyrimidinyl)amino]carbonyl]amino]sulfonyl]-1-methyl-1 H-pyrazole-4-
carboxylate, and its metabolites and degradates (compliance with the
tolerance level specified is to be determined by measuring only those
halosulfuron-methyl residues convertible to 3-chloro-1-methyl-5-
sulfamoylpyrazole-4-carboxylic acid, expressed as the stoichiometric
equivalent of halosulfuron-methyl) in or on pea and bean, succulent
shelled, subgroup 6B; pea and bean, dried shelled, except soybean,
subgroup 6C; vegetables, tuberous and corm, subgroup 1C; bushberry,
subgroup 13-07B; apple; rhubarb; and okra at 0.05 ppm. A practical
analytical method, gas chromatography with a nitrogen-specific
detector, is available for enforcement purposes. The limit of detection
is 0.003 ppm. Contact: Sidney Jackson, (703) 305-7610;
[email protected].
4. PPs 9E7588 and 9F7589. (EPA-HQ-OPP-2009-0636). Bayer
CropScience LP., 2 T.W. Alexander Dr., Research Triangle Park, NC
27709, proposes to establish a tolerance in 40 CFR part 180 for
residues of the herbicide indaziflam, N-[(1R,2S)-2,3-dihydro-2,6-
dimethyl-1H-inden-1-yl-1,3,5-triazine-2,4-diamine]-6-(1-fluoroethyl)]
and its fluoroethyl-indaziflam metabolite, in or on fruit, pome, group
11; fruit, citrus, group 10; fruit, stone, group 12; nut, tree, group
14; pistachio; grape; and olive at 0.01 ppm; almond, hulls at 0.2 ppm
PP 9F7589; and the import tolerance for sugarcane, sugar, refined at
0.01 ppm PP 9E7588. Indaziflam residues are quantified in raw
agricultural commodities by high pressure liquid chromatography/triple
stage quadrupole mass spectrometry (LC/MS/MS) using the stable
isotopically labeled analytes as internal standards. The LOQ of each
analyte was 0.005 ppm for all commodities. Contact: Beth Benbow, (703)
347-8072; [email protected].
5. PP 9E7604. (EPA-HQ-OPP-2009-0813). Interregional Research
Project No. 4, 500 College Road East, Suite 201W, Princeton, NJ, 08540-
6635, in cooperation with Bayer CropScience, Research Triangle Park, NC
27709, proposes to establish a tolerance in 40 CFR part 180 for
residues of the herbicide glufosinate-ammonium (butanoic acid, 2-amino-
4-(hydroxymethylphosphinyl)-monoammonium salt) and its metabolites, 2-
acetamido-4-methylphosphinico-butanoic acid and 3-methylphosphinico-
propionic acid, expressed as 2-amino-4-
(hydroxymethylphosphinyl)butanoic acid equivalents, in or on corn,
sweet, kernel plus cob with husks removed at 0.2 ppm; corn, sweet,
forage at 4.0 ppm; and corn, sweet, stover at 6.0 ppm. The enforcement
analytical method utilizes gas chromatography for detecting and
measuring levels of glufosinate-ammonium and its metabolites with a
general limit of quantification of 0.05 ppm. This method allows
detection of residues at or above the proposed tolerances. Contact:
Sidney Jackson, (703) 305-7610; [email protected].
6. PP 9E7607. (EPA-HQ-OPP-2009-0814). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, in cooperation with Syngenta Crop Protection, Inc., 410 Swing
Rd., Greensboro, NC 27419, proposes to establish a tolerance in 40 CFR
part 180 for residues of the herbicide, S-metolachlor,S-2-chloro-N-(2-
ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide, its R-
enantiomer, and its metabolites, determined as the derivatives, 2-[(2-
ethyl-6-methylphenyl)amino]-1-propanol and 4-(2-ethyl-6-methylphenyl)-
2-hydroxy-5-methyl-3-morpholinone, each expressed as the parent
compound, in or on carrot at 0.3 ppm; cucumber, okra, sesame seed, and
sorghum sweet, at 0.1 ppm; Brassica, leafy greens, subgroup 5B, and
turnip, greens at 1.2 ppm; melon, subgroup 9A, and caneberry, subgroup
13-07A at 0.08 ppm; blueberry, lowbush at 1.4 ppm; bushberry, subgroup
13-07B at 0.15 ppm; onion, bulb, subgroup 3-07A at 0.1 ppm; and onion,
green, subgroup 3-07B at 2.0 ppm. The Pesticide Analytical Manual (PAM)
Vol. II, Pesticide Regulation 180.368 lists a GC/NPD method (Method 1)
for determining residues in/on plants and a gas chromatography/mass
spectrum detector (GC/MSD) method for determining residues in livestock
commodities. These methods determine residues of S-metolachlor and its
metabolites as either CGA-37913 or CGA-49751 following acid hydrolysis.
The LOQ for the method is 0.03 ppm for CGA-37913 and 0.05 ppm for CGA-
49751. Syngenta has also developed a chiral specific analytical method
to allow for the determination of residues that are specific to S-
metolachlor. It is this chiral specific method that Syngenta and IR-4
proposes for future use as the analytical enforcement method in support
of these requested tolerances. Syngenta No. 1848-01 was used in several
of the studies in this petition to analyze agricultural commodities.
The latter chiral specific method is the same as the updated tolerance
enforcement method, except that chiral chromatography and LC/MS/MS are
used to separate and quantitate the hydrolysis products SYN-506357 (s-
configured enantiomer of CGA-37913) and SYN-508500 (s-configured
enantiomer of CGA-49751). Contact: Sidney Jackson, (703) 305-7610;

7. PP 9E7611. (EPA-HQ-OPP-2009-0774). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, in cooperation with Syngenta Crop Protection, Inc., 410 Swing
Rd., Greensboro, NC 27419, proposes to establish a tolerance in 40 CFR
part 180 for residues of the fungicide chlorothalonil
(tetrachloroisophthalonitrile) and its metabolite 4-hydroxy-2,5,6-
trichloroisophthalonitrile, in or on berry, low growing subgroup 13-07G
at 0.01 ppm; bushberry subgroup 13-07B at 1 ppm; onion, bulb, subgroup
3-07A at 0.5 ppm; and onion, green, subgroup 3-07B at 5 ppm. An
adequate residue analytical method (gas chromatography) is available
for enforcement purposes. The method is listed in the PAM Vol. II.

8. PP 9E7612. (EPA-HQ-OPP-2009-0775). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, proposes to establish a tolerance in 40 CFR part 180 for
residues of the fungicide flutolanil, N-(3-(1-methylethoxy)phenyl)-2-
(trifluoromethyl)benzamide and its metabolites converted to 2-
(trifluoromethyl) benzoic acid and calculated as flutolanil in or on
ginseng at 3.5 ppm; vegetable, Brassica, leafy, group 5 at 0.11 ppm;
and turnip, greens at 0.11 ppm. Residues of flutolanil and M-4 are
extracted from macerated samples with acetone or a mixture of methanol
and water. For cabbage and ginseng, an aliquot of the extract is
diluted with water and analyzed using high performance liquid
chromatography-mass spectrometry/mass spectrometry (HPLC-MS/MS). For
broccoli and mustard greens, the acetone extract is diluted with water
and the residues are partitioned into a mixture of ethyl acetate and
[[Page 867]]
dichloromethane. This solvent is dispelled and the residue is
reconstituted in acetone for purification through Florisil. The
purified eluent is taken to dryness and the residues are reconstituted
in a mixture of acetonitrile and water. Residues of flutolanil and M-4
are chromatographed and quantified using an HPLC-MS/MS. The LOQ is 0.05
ppm for each flutolanil and M-4. Contact: Laura Nollen, (703) 305-7390;
[email protected].
9. PP 9E7615. (EPA-HQ-OPP-2009-0801). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, proposes to establish a tolerance in 40 CFR part 180 for
residues of the fungicide cyazofamid, 4-chloro-2-cyano-N,N-dimethyl-5-
(4-methylphenyl)-1H-imidazole-1-sulfonamide and its metabolite CCIM, 4-
chloro-5-(4-methylphenyl)-1H-imidazole-2-carbonitrile, expressed as
cyazofamid, in or on Brassica, head and stem, subgroup 5A at 1.2 ppm;
Brassica, leafy greens, subgroup 5B at 12.0 ppm; turnip, greens at 12.0
ppm; spinach at 9.0 ppm; and hops at 10.0 ppm. Residues of cyazofamid
and CCIM were extracted from samples (5 g. for broccoli, cabbage,
mustard greens & spinach; 1 g. for hops) with acetonitrile. The
combined extracts were partitioned with hexane and then reduced to 1-2
mL. The residues were dissolved in 20% acetonitrile/water and passed
through a Nexus or Strat-X Polymeric solid phase extraction column
(SPE). The residues were eluted with 60/40 acetonitrile/water and then
diluted in 50/50 acetonitrile/water. The samples were quantitated by
liquid chromatography (LC)/MS/MS. Contact: Laura Nollen, (703) 305-

Fluopyram was determined to be the only analyte required for
analysis based on the metabolic profile in plants, the short pre-
harvest intervals analyzed, and results from preliminary residues
trials in Europe. The analytical method involves, solvent extraction,
filtration, and addition of an isotopically labeled internal standard
followed by solid phase extraction. Quantitation is by high performance
liquid chromatography-electrospray ionization/tandem mass spectrometry
(LC/MS/MS). Contact: Shaja B. Joyner, (703) 308-3194;

11. PP 8F7509. (EPA-HQ-OPP-2009-0796). Valent U.S.A. Corporation,
1600 Riviera Ave., Suite 200, Walnut Creek, CA, proposes to establish a
tolerance in 40 CFR part 180 for residues of the herbicide bispyribac-
sodium; benzoic acid; 2,6-bis-((4,6-dimethoxy-2-pyrimidinyl)oxy)-,
sodium salt; and its des-methyl metabolite, sodium 2-(4,6-
dimethoxypyrimidin-2-yl)oxy-6-(4-hydroxy-6-methoxypyrimidin-2-yl)
benzoate in or on freshwater fish tissue at 0.01 ppm. Practical
analytical methods for detecting and measuring levels of bispyribac-
sodium and its metabolites have been developed and validated in/on all
appropriate plant and animal matrices. An analytical method for
detecting bispyribac-sodium and its des methyl metabolite (KIH 2023) in
fish tissue has been submitted with this petition. The LOQ of
bispyribac-sodium and the metabolite in the analytical method for fish
tissue is 10 ppb (0.01 ppm); which will allow monitoring for residues

Amended Tolerances
1. PP 9E7598. (EPA-HQ-OPP-2009-0812). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, in cooperation with Arysta LifeScience North America LLC., 15401
Weston Parkway, Suite 150, Cary, NC 27513, proposes to amend the
tolerances in 40 CFR part 180.599 by revising the tolerance expression
to read tolerances are established for the residues of the insecticide
acequinocyl, including its metabolites and degradates. Compliance with
the tolerance levels specified is to be determined by measuring only
the sum of acequinocyl, 2-(acetyloxy)-3-dodecyl-1,4-naphthalenedione,
and its metabolite, 2-dodecyl-3-hydroxy-1,4-napthoquinone, calculated
as the stoichiometric equivalent of acequinocyl and by establishing a
tolerance for the residues of acequinocyl, including its metabolites
and degradates in or on vegetables, fruiting, group 8 at 0.7 ppm; okra
at 0.7 ppm; bean, edible podded at 0.25 ppm; and hop, dried cones at
3.5 ppm. The analytical method to quantitated residues of acequinocyl
and acequinocyl-OH in/on fruit crops utilizes high pressure liquid
chromatography-mass spectrometry (HPLC/MS/MS) detection for fruiting
vegetables; crop group 8 (tomatoes and peppers) and LC/MS/MS for snap-
bean; edible podded; and hop; dried cones. The lowest level for method
validation (LLMV) was 0.01 ppm for acequinocyl and 0.025 ppm for
acequinocyl-OH. Contact: Sidney Jackson, (703) 305-7610;
[email protected].
2. PP 9E7625. (EPA-HQ-OPP-2009-0843). The Interregional Research
Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ
08540, proposes to amend the tolerance in 40 CFR 180.184(c) by deleting
the regional tolerance for residues of the herbicide linuron, (3-(3,4-
dichlorophenyl)-1-methoxy-1-methylurea) and its metabolites convertible
to 3,4-dichloroaniline, calculated as linuron, in or on parsley, leaves
at 0.25 ppm. Contact: Laura Nollen, (703) 305-7390;
[email protected].
3. PP 9F7576. (EPA-HQ-OPP-2009-0673). BASF Corporation, 26 Davis
Dr., Research Triangle Park, NC 27709, proposes to amend by increasing
the tolerance in 40 CFR 180.361 for the combined residues of the
herbicide pendimethalin, N-(1-ethylpropyl)-3,4-dimethyl-2,6-
dinitrobenzenamine, and its metabolite 4-[(1-ethylpropyl)amino]-2-
methyl-3,5-dinitrobenzyl alcohol in or on alfalfa forage to 3.5 ppm. In
plants, the method is aqueous organic solvent extraction, column clean-
up, and quantitation by gas chromatograph (GC). The method has a LOQ of
0.05 ppm for pendimethalin and the alcohol metabolite. Contact: Philip
V. Errico, (703) 305-6663; [email protected].
New Tolerance Exemptions
