I. General Information

A. Does this Action Apply to Me?

    You may be potentially affected by this action if you are an 
agricultural producer, food manufacturer, or pesticide manufacturer. 
Potentially affected entities may include, but are not limited to:
     Crop production (NAICS code 111).
     Animal production (NAICS code 112).
     Food manufacturing (NAICS code 311).
     Pesticide manufacturing (NAICS code 32532).
    This listing is not intended to be exhaustive, but rather provides 
a guide for readers regarding entities likely to be affected by this 
action. Other types of entities not listed in this unit could also be 
affected. The North American Industrial Classification System (NAICS) 
codes have been provided to assist you and others in determining 
whether this action might apply to certain entities. If you have any 
questions regarding the applicability of this action to a particular 
entity, consult the person listed at the end of the pesticide petition 
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; nollen.laura@epa.gov.
    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; kearns.rosemary@epa.gov.

    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; 
jackson.sidney@epa.gov.
     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; benbow.bethany@epa.gov.
    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; jackson.sidney@epa.gov.
     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; 
jackson.sidney@epa.gov.

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;

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-

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;

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; errico.philip@epa.gov.
