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 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.

New Tolerance Exemptions

     1. PP 8E7316. (EPA-HQ-OPP-2008-0858). Rhodia Inc. c/o SciReg, 
Inc., 12733 Director's Loop, Woodbridge, VA 22192, proposes to 
establish an exemption from the requirement of a tolerance in 40 CFR 
180.920 for residues of the alkyl (C10-C16) dimethylamine oxide (CAS 
No. 70592-80-2) in or on growing crops when used as a wetting-agent in 
pesticide formulations applied pre-harvest to all raw agricultural 
commodities. Because this petition is a request for an exemption from 
the requirement of a tolerance, no analytical method is required.

polymers with Bu acrylate, tert-Bu acrylate and styrene, minimum number 
average molecular weight (in amu) 10,000 (CAS No. 204142-80-3) 
hereafter referred to as styrene-butylacrylate copolymer, under 40 CFR 
180.960, when used as a pesticide inert ingredient in pesticide 
formulations in or on all food commodities without numerical 
limitations. Because this petition is a request for an exemption from 
the requirement of a tolerance, no analytical method is required.
