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 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 7E7294. (EPA-HQ-OPP-2008-0854). Dow AgroSciences LLC, 9330
Zionsville Rd., Indianapolis, IN 46268, proposes to establish a
tolerance in 40 CFR part 180 for residues of the fungicide
meptyldinocap as the parent 2,4-dinitro-6-(1-methylheptyl) phenyl
crotonate and the 2,4-dinitro-6-(1-methylheptyl) phenol metabolite in
or on grape; grape, wine; or grape, juice at 0.3 parts per million
(ppm). This petition is for the establishment of tolerances for
meptyldinocap for grapes and processed grapes to cover registered uses
of this active ingredient in other countries, e.g., in Europe and
Chile, for grapes and wine imported to the United States. The database
which supports meptyldinocap builds on the historical relationship of
meptyldinocap to dinocap. Dinocap is a mixture of six DNOPC isomers
(both ortho and para methylheptyl, ethylhexyl, and propylpentyl
crotonate isomers). The new meptyldinocap is an enhanced offering of
the single 2,4-DNOPC methylheptyl isomer. Overall, meptyldinocap has an
improved toxicological profile relative to the older dinocap. At times,
data for dinocap is used as a conservative surrogate for meptyldinocap.
Adequate methods are available for determination of meptyldinocap
residues in plant commodities. There is a practical, validated method
(DOS/220) for the quantification of meptyldinocap and the related
phenol metabolite in grapes. Key aspects of the method include
conversion of parent 2,4-DNOPC to the phenol metabolite and final
quantification based on liquid chromatography/mass spectrometry (LC/MS/
MS) of 2,4-DNOP. The level of quantitation (LOQ) for meptyldinocap (as
single 2,4-DNOPC methylheptyl isomer) is 0.025 ppm and the level of
detection (LOD) is 0.01 ppm for grapes. These levels are suitable for
detecting and measuring levels of meptyldinocap in or on food and allow
monitoring of food residues at or above the level set for these
tolerances. In addition, a multi-residue enforcement method DFG S19 is
available. It has been validated successfully for the determination of
dinocap in plant materials including grapes. It also relies on
confirmation of the phenol derivatives via LC/MS/MS. Contact: Tamue L.
Gibson, (703) 305-9096, gibson.tamue@epa.gov.
2. PP 8E7313. (EPA-HQ-OPP-2008-0840). Syngenta Crop Protection,
P.O. Box 18300, Greensboro, NC 27419, proposes to establish a tolerance
in 40 CFR part 180 for residues of the fungicide fenpropidin, 1-[3-[4-
(1, 1-dimethylethyl) phenyl]-2-methyl-propyl]-piperidine in or on
banana, whole fruit at 10 ppm. An adequate, validated method is
available for enforcement purposes (method REM
[[Page 16868]]
164.09). Residues of fenpropidin are extracted from crop samples by
shaking with methanol: Water (80:20, v/v). Extracts are centrifuged and
aliquots (1 mL = 0.1 g) are diluted with 90:10:0.2 water: Acetonitrile:
Acetic acid (v/v/v). Separation is achieved by high performance liquid
chromatography with a Synergi Polar-RP 80A column (50 x 3.0 mm, 4
[mu]m) and a mobile phase gradient of (1) acetonitrile and (2) 0.2% (v/
v) acetic acid in water. Final determination is carried out with triple
quadrupole mass spectrometric detection (LC-MS/MS, Applied Biosystems
API 3000 detector). A primary transition with m/z 274.3 [rarr] 147.0 as
well as a confirmatory transition with m/z 274.2 [rarr] 117.0 are
monitored. Quantification is by external standardization. Contact:

Amended Tolerances
1. PP 8E7411. (EPA-HQ-OPP-2008-0814). IR-4, 500 College Rd. East,
Suite 201, Princeton, NJ 08540, proposes to revise the tolerance
expression for the Berry Crop Group 13 to become the Berry and Small
Fruit Crop Group 13 per the Pesticide Tolerance Crop Grouping Program
published in the Federal Register, December 7, 2007 (72 FR 69150; FRL-
8343-1). The proposed new tolerance expressions for the Berry and Small
Crop group 13 for the tolerances in 40 CFR 180.565 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] are as follows in or on: Caneberry subgroup 13-07A at 0.35
ppm; bushberry subgroup 13-07B at 0.2 ppm; fruit, small, vine climbing
subgroup 13-07F, except fuzzy kiwifruit at 0.2 ppm; low growing berry
subgroup 13-07G, except cranberry at 0.3 ppm. The existing tolerance on
cranberry at 0.02 ppm will not be changed. Also, the IR-4 is requesting
the following tolerances be deleted: Vegetable, root, except sugar
beet, subgroup 1B at 0.02 ppm; caneberry subgroup 13A at 0.35 ppm;
bushberry subgroup 13B at 0.20 ppm; grape at 0.20 ppm; strawberry at
0.30 ppm; lingonberry at 0.20 ppm; juneberry at 0.20 ppm; and salal at
0.20 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 UV or MS detections. The LOD for each
analyte of this method is 1.25 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.

2. PP 8F7416. (EPA-HQ-OPP-2008-0771). Bayer CropScience, P.O. Box
12014, 2 T.W. Alexander Dr., Research Triangle Park, NC 27709, proposes
to amend the tolerance in 40 CFR 180.586 by increasing the tolerance
for residues of the insecticide clothianidin, (E)-1-(2-chloro-1,3-
thiazol-5-ylmethyl)-3-methyl-2-nitroguanidine and its metabolite, TMG,
N-(2-chloro-5-thiazolylmethyl)-N'-methylguanidine in or on potato from
0.05 ppm to 0.6 ppm. In plants and plant products, the residue of
concern, parent clothianidin and its metabolite, TMG, N-(2-chloro-5-
thiazolylmethyl)-N'-methylguanidine], can be determined using HPLC with
Electrospray MS/MS detection. In an extraction efficiency testing, the
plant residues method has also demonstrated the ability to extract aged
clothianidin residue. Although the plant residues LC-MS/MS method is
highly suitable for enforcement method, an LC-UV method has also been
developed which is suitable for enforcement (monitoring) purposes in
all relevant matrices. Contact: Kable Bo Davis, (703) 306-0415,

3. PP 8E7460. (EPA-HQ-OPP-2008-0945). IR-4, IR-4 Project
Headquarters, Rutgers, The State University of New Jersey, 500 College
Rd. East, Suite 201 W, Princeton, NJ 08450, proposes to delete the
tolerance in 40 CFR 180.586 for residues of the insecticide
clothianidin, (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-
nitroguanidine, in or on potato at 0.05 ppm since it will be superseded
by the proposed tolerance on subgroup 1C in paragraph 7. under ``New
Tolerances'' in this unit. Contact: Laura Nollen, (703) 305-7390,
nollen.laura@epa.gov.
4. PP 8E7462. (EPA-HQ-OPP-2008-0885). The IR-4 Project
Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540,
proposes to amend the tolerances in 40 CFR 180.568 by revoking the
existing tolerance for residues of the herbicide flumioxazin, 2-[7-
fluoro-3,4-dihydro-3-oxo-4-(2-propynyl)-2H-1,4-benzoxazin-6-yl]-
4,5,6,7-tetrahydro-1H-isoindole-1,3(2H)-dione in or on almonds because
a tolerance on nut, tree, group 14 has been established; and by
deleting the existing tolerance for melon subgroup 9A because it will
be superseded by the proposed tolerance for cucurbit, group 9 in the
section ``New Tolerances'' in paragraph 9. in this unit. Practical
analytical methods for detecting and measuring levels of flumioxazin
have been developed and validated in/on all appropriate agricultural
commodities and respective processing fractions. The LOQ of flumioxazin
in the methods is 0.02 ppm which will allow monitoring of food with
residues at the levels proposed for the tolerances. Contact: Laura
Nollen, (703) 305-7390, nollen.laura@epa.gov.
