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 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
[[Page 35803]]
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 0E7723. (EPA-HQ-OPP-2010-0471). IR-4, 500 College Road East,
Suite 201W, Princeton, NJ 08540, proposes to establish tolerances in 40
CFR part 180 for residues of the insecticide novaluron N-[[[3-chloro-4-
[1,1,2-trifluoro-2-trifluoromethoxy)ethoxy]phenyl] amino]carbonyl]-2,6-
difluorobenzamide, in or on corn, sweet, kernals plus cob with husks
removed at 0.05 parts per million (ppm); corn, sweet, forage at 20 ppm;
and corn, sweet, stover at 50 ppm. Makhteshim-Agan of North America,
Inc., 4515 Falls of Neuse Road, Raleigh, NC 27609, is the manufacturer
and basic registrant of novaluron. Makhteshim-Agan of North America,
Inc., prepared and summarized the following information in support of
the subject pesticide petition for novaluron. Adequate analytical
enforcement methods, gas chromatography/electron capture detector (GC/
ECD) and a high performance liquid chromatography/ultraviolet method
(HPLC/UV) for enforcing tolerances of novaluron residues in or on
different matrices are available, as published in the Federal Register
of January 27, 2010 (75 FR 4274) (FRL-8807-2). A method validation was
conducted both prior to sample analysis and concurrently with sample
analysis, determining that the method recoveries were in the range. The
limit of quantitation (LOQ) for the method in K+CWHR, forage and stover
was calculated to be 0.040, 0.052 and 0.049 ppm, respectively. The
lowest level of method validation (LLMV) for novaluron in corn forage,
stover and K+CWHR was 0.05 ppm. Contact: Laura Nollen, (703) 305-7390,
e-mail address: [email protected].
2. PP 0F7708. (EPA-HQ-OPP-2010-0466). Makhteshim-Agan of North
America, Inc., 4515 Falls of Neuse Road, Raleigh, NC 27609, proposes to
establish tolerances in 40 CFR part 180 for residues of the insecticide
novaluron (N-[[[3-chloro-4-[1,1,2-trifluoro-2-
trifluoromethoxy)ethoxy]phenyl]amino]carbonyl]-2,6-difluorobenzamide)
in or on all food commodities (other than those already covered by a
higher tolerance as a result of use on growing crops) in food handling
establishments where food products are held, processed or prepared at
0.01 ppm. An adequate analytical enforcement method GC/ECD and a HPLC/
UV method for enforcing tolerances of novaluron residues in or on
different matrices are available. Concerning this petition, a
validation method was conducted determining residue concentrations of
novaluron in or on butter, meat, milk, bread, lettuce and typical
dinner plates serving as representative commodities in a simulated
food-handling establishment to which novaluron was applied. Contact:

meat byproducts except liver of cattle, goat, hog, horse, and sheep at
0.01 ppm; fat of cattle, goat, hog, horse, and sheep at 0.05 ppm; liver
of cattle, goat, hog, horse, and sheep at 0.8 ppm; meat, meat
byproducts, fat, and eggs of poultry at 0.01 ppm; milk at 0.01 ppm, and
cream, at 0.03 ppm. Adequate analytical methodology is available for
enforcement purposes. An analytical method has been developed and
independently validated for the detection and quantification of
picoxystrobin and metabolites in various crop matrices including
cereals, soybean, dried legume, canola, lettuce, and orange matrices.
The method was validated at 0.010 and 0.10 ppm in all matrices using an
LC/MS/MS system operating with an electrospray interface (ESI) in
positive ion mode. The analytical method is suitable for enforcement/
monitoring and data generation for regulatory studies. An analytical
method has been developed and independently validated for the
detection, quantification and confirmation of picoxystrobin residues in
animal tissues including chicken egg, bovine whole and skim milk and
cream and bovine muscle, liver, kidney and fat. The method quantifies
picoxystrobin in the animal matrices at levels of approximately 0.010
mg/kg using a HPLC/ESI-MS/MS system. The analytical method is suitable
for enforcement/monitoring and data generation for regulatory studies.

at 0.01 ppm; corn, sweet, stover at 0.01 ppm; and corn, sweet, kernel
plus cobs with husks removed at 0.01 ppm. Adequate analytical
methodology is available for data collection enforcing of thiabendazole
residues. The Pesticide Analytical Manual (PAM) Vol. II lists four
spectrophotofluorometric methods (Methods I, A, B and C) for
determining residues of thiabendazole per se in or on plant
commodities, and one spectrophotofluorometric method (Method D) for
determining residues of thiabendazole and 5-hydroxy-thiabendazole in
milk. Contact: Janet Whitehurst, (703) 305-6129, e-mail address:

8. PP 9F7679. (EPA-HQ-OPP-2010-0267). Bayer CropScience LLC, 2 T.
W. Alexander Drive, Research Triangle Park, NC 27709, proposes to
establish tolerances in 40 CFR part 180 for residues of the herbicide
safener, mefenpyr-diethyl including its metabolites and degradates.
Compliance with the tolerance levels specified is to be determined by
measuring residues of mefenpyr-diethyl ((RS)-1-(2,4-dichlorophenyl)-5-
methyl-2-pyrazoline-3,5-dicarboxylic acid) and its
dichlorophenylpyrazoline metabolites in or on sorghum, grain at 0.01
ppm; sorghum, forage at 0.1 ppm; sorghum, stover at 0.05 ppm; grass,
hay at 0.05 ppm; and grass, forage at 1.5 ppm. An enforcement method
for plants has been developed and radiovalidation and independent
laboratory validation (ILV) conducted. The EPA has concluded that this
method is suitable for food tolerance enforcement of mefenpyr-diethyl
and its 2,4-dichlorophenyl-pyrazoline metabolites. Contact: Bethany
Benbow, (703) 347-8072, e-mail address: [email protected].
9. PP 9F7680. (EPA-HQ-OPP-2010-0266). Bayer CropScience LLC, 2 T.
W. Alexander Drive, Research Triangle Park, NC 27709, proposes to
establish tolerances in 40 CFR part 180 for residues of the herbicide
pyrasulfotole including its metabolites and degradates. Compliance with
the tolerance levels specified is to be determined by measuring
residues of pyrasulfotole (AE 0317309) (5-hydroxy-1,3-dimethyl-1H-
pyrazol-4-yl)-[2-(methylsulfonyl)-4-(trifluoromethyl)-phenyl]-methanone
and its metabolite (5-Hydroxy-3-methyl-1H-pyrazol-4-yl)-[2-
(methylsulfonyl)-4-(trifluoromethyl)phenyl] methanone, calculated as
the stoichiometric equivalent of pyrasulfotole, in or on sorghum, grain
at 0.8 ppm; sorghum, forage at 1.2 ppm; sorghum, stover at 0.35 ppm;
grass, hay at 2.5 ppm; and grass, forage at 10 ppm. The analytical
method is an LC/MS/MS method which quantifies pyrasulfotole and its
metabolite (5-Hydroxy-3-methyl-1H-pyrazol-4-yl)[2-(methylsulfonyl)-4-
(trifluoromethyl) phenyl]methanone with an LOQ of 0.01 mg/kg.
Pyrasulfotole and its metabolite are solvent extracted, hydrolyzed to
released conjugated residues and purified by C18 solid phase
extraction. Residues are quantified by LC/MS/MS using isotopically
labeled internal standards. Validation of the methodology for the
determination of pyrasulfotole and its metabolite demonstrated that it
could accurately determine residues at the LOQ of 0.01 ppm in all
appropriate matrices. Pyrasulfotole and its metabolite are stable for
at least 11 months for the above matrices. Contact: Bethany Benbow,

Amended Tolerances
1. PP 0E7723. (EPA-HQ-OPP-2010-0471). IR-4, 500 College Road East,
Suite 201W, Princeton, NJ 08540, proposes to increase the tolerances in
40 CFR 180.598 for residues of the insecticide novaluron, N-[[[3-
chloro-4-[1,1,2-trifluoro-2-trifluoromethoxy)ethoxy]
phenyl]amino]carbonyl]-2,6-difluorobenzamide, in or on milk from 1.0 to
1.5 ppm; and milk, fat from 20 to 35 ppm. Makhteshim-Agan of North
America, Inc., 4515 Falls of Neuse Road, Raleigh, NC 27609, is the
manufacturer and basic registrant of novaluron. Makhteshim-Agan of
North America, Inc., prepared and summarized the following information
in support of the subject pesticide petition for novaluron. Adequate
analytical enforcement methods, GC/ECD method and a HPLC/UV method for
enforcing tolerances of novaluron residues in or on different matrices
are available, as published in the Federal Register of January 27, 2010
(75 FR 4274) (FRL-8807-2). A method validation was conducted both prior
to sample analysis and concurrently with sample analysis, determining
that the method recoveries were in the range. The LOQ for the method in
K+CWHR, forage and stover was calculated to be 0.040, 0.052 and 0.049
ppm, respectively. The LLMV for novaluron in corn forage, stover and
K+CWHR was
[[Page 35805]]
0.05 ppm. Contact: Laura Nollen, (703) 305-7390, e-mail address:

2. PP 9F7622. (EPA-HQ-OPP-2010-0287). Valent U.S.A. Company, 1600
Riviera Ave., Suite 200, Walnut Creek, CA 94596-8025, proposes to amend
the tolerance in 40 CFR 180.617 by decreasing the established tolerance
for residues of the fungicide metconazole, 5-[(4-chlorophenyl)methyl]-
2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol, measured as
the sum of cis- and trans- isomers, in or on nut, tree (crop group 14)
from 0.04 ppm to 0.02 ppm. Independently validated analytical methods
have been submitted for analyzing parent metconazole residues with
appropriate sensitivity for all canola crop and processed commodities
for which a tolerance is being requested. Contact: Tracy Keigwin, (703)

3. PP 9F7678. (EPA-HQ-OPP-2010-0268). Bayer CropScience LLC, 2 T.
W. Alexander Drive, Research Triangle Park, NC 27709, proposes to amend
the 40 CFR 180.324 by revising tolerances for residues of the
herbicide, bromoxynil including its metabolites and degradates.
Compliance with the tolerance levels specified is to be determined by
measuring residues of bromoxynil (3,5-dibromo-4-hydroxybenzonitrile),
in or on sorghum, grain at 0.2 ppm; grass, hay at 5.0 ppm; and grass,
forage at 18 ppm. Since bromoxynil already has tolerances on sorghum
and grass commodities adequate analytical methods are in place to
support the desired uses. Contact: Bethany Benbow, (703) 347-8072, e-
mail address: [email protected].
4. PP 9F7680. (EPA-HQ-OPP-2010-0266). Bayer CropScience LLC, 2 T.

measuring residues of pyrasulfotole (AE0317309) (5-hydroxy-1,3-
dimethyl-1H-pyrazol-4-yl)[2-(methylsulfonyl)-4-
(trifluoromethyl)phenyl]-methanone and its metabolite (5-Hydroxy-3-
methyl-1H-pyrazol-4-yl-[2-(methylsulfonyl)-4-(trifluoromethyl)phenyl]
methanone, calculated as the stoichiometric equivalent of
pyrasulfotole, in or on cattle, goat, hog, sheep, horse, meat at 0.04
ppm; cattle, goat, hog, sheep, horse, fat at 0.04 ppm; cattle, goat,
hog, sheep, horse, meat byproducts, except liver at 2 ppm; and cattle,
goat, hog, sheep, horse, liver at 8 ppm. The analytical method is an
LC/MS/MS method which quantifies pyrasulfotole and its metabolite (5-
Hydroxy-3-methyl-1H-pyrazol-4-yl)[2-(methylsulfonyl)-4-
(trifluoromethyl) phenyl]methanone with an LOQ of 0.01 mg/kg.
Pyrasulfotole and its metabolite are solvent extracted, hydrolyzed to
released conjugated residues and purified by C18 solid phase
extraction. Residues are quantified by LC/MS/MS using isotopically
labeled internal standards. Validation of the methodology for the
determination of pyrasulfotole and its metabolite demonstrated that it
could accurately determine residues at the LOQ of 0.01 ppm in all
appropriate matrices. Pyrasulfotole and its metabolite are stable for
at least 11 months for the above matrices. Contact: Bethany Benbow,

New Tolerance Exemptions
1. PP 0E7701. (EPA-HQ-OPP-2008-0095). Ag-Chem Consulting, 12208
Quinque Lane, Clifton, VA 21024, on behalf of LG Life Science, 910
Sylvan Ave., Englewood Cliffs, NJ 07632, proposes to establish an
exemption from the requirement of a tolerance for residues of
polyoxyethylene mono (tristyrylphenyl)ether (CAS No. 99734-09-5)
applied to postharvest crops under 40 CFR 180.910 when used as a
pesticide inert ingredient as a surfactant with a maximum of 10.0% by
weight in pesticide formulations applied to food areas and food contact
surfaces in food service and food handling establishments. The
petitioner believes no analytical method is needed because requirements
for an analytical method are not applicable to a request to establish
an exemption from the requirement of a tolerance. Contact: Karen Samek,
(703) 347-8825, e-mail address: [email protected].
2. PP 9E7660. (EPA-HQ-OPP-2010-0429). BASF Corporation, 100 Campus
Dr., Florham Park, NJ 07932, proposes to establish an exemption from
the requirement of a tolerance for residues of Acetic acid ethenyl,
polymer with oxirane (CAS No. 25820-49-9) when used as a pesticide
inert ingredient as a surfactant in pesticide formulations without
limitation. The petitioner believes no analytical method is needed
because requirements for an analytical method are not applicable to a
request to establish an exemption from the requirement of a tolerance.
