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 these petitions so that the public has an 
opportunity to comment on these requests for the establishment or 
modification of regulations for residues of pesticides in or on food 
commodities. Further information on the petitions may be obtained 
through the petition summaries referenced in this unit.

New Tolerances

     1. PP 9E7544. (EPA-HQ-OPP-2009-0289). The Interregional Research 
Project Number 4 (IR-4), IR-4 Project Headquarters, 500 College Rd. 
East, Suite 201 W, Princeton, NJ 08540, proposes to establish a 
tolerance in 40 CFR part 180 for residues of the insecticide 
acetamiprid, N1-[(6-chloro-3-pyridyl)methyl]- N2-cyano-N1-
methylacetamidine, in or on fruit, small, vine climbing, except fuzzy 
kiwifruit, subgroup 13-07F at 0.35 parts per million (ppm); and 
tolerances with regional restrictions for clover, forage at 0.10 ppm; 
clover, hay at 0.01 ppm; and tea at 50 ppm. Based upon the metabolism 
of acetamiprid in plants and the toxicology of the parent and 
metabolites, quantification of the parent acetamiprid is sufficient to 
determine toxic residues. As a result a method has been developed which 
involves extraction of acetamiprid from crops with methanol and 
analysis by liquid chromatography/mass spectrometry/mass spectrometry 
(LC/MS/MS) methods. The limit of quantification (LOQ) and the limit of 
detection (LOD) for the method are calculated to be 0.0076 ppm and 
0.0025 ppm for clover forage, respectively while the LOQ and the LOD 
for the method for clover hay are calculated to be 0.0082 ppm and 
0.0027 ppm, respectively. The LOQ and LOD for grape are calculated to 
be 0.0064 ppm and 0.0021 ppm, respectively. The LOQ and LOD for 
greenhouse-grown tomatoes were 0.0075 ppm and 0.0025, respectively.

     2. PP 9E7550. (EPA-HQ-OPP-2009-0943). Bayer CropScience, LP, P.O. 
Box 12014, 2 T.W. Alexander Dr., Research Triangle Park, NC 27709-2014, 
proposes to establish a tolerance in 40 CFR part 180 for residues of 
the insecticide ethiprole; 1 H-pyrazole-3-carbonitrile, 5-amino-1-[2,6-
dichloro-4-(trifluromethyl)phenyl]-4-(ethylsulfinyl), and its sulfones 
metabolite (RPA 097973), 5-amino-1-(2,6-dichloro-4-
trifluoromethylphenyl)-4-ethylsulfonylpyrazole-3-carbonitrile,

[[Page 41900]]

expressed as parent equivalent in or on imported tea (dried and 
instant) at 50 ppm; imported rice (grain and bran) at 3.0 ppm; meat 
(cattle, goat, hog, horse, sheep) at 0.01 ppm; fat (cattle, goat, hog, 
horse, sheep) at 0.1 ppm; liver (cattle, goat, hog, horse, sheep) at 
0.1 ppm; meat by-products, except liver (cattle, goat, hog, horse, 
sheep) at 0.02 ppm; milk at 0,01 ppm; milk, fat at 0.1 ppm; poultry, 
meat at 0.01 ppm; poultry, fat at 0.1 ppm; poultry, meat by-products at 
0.05 ppm; and eggs at 0.05 ppm. Practical enforcement analytical 
methods for detecting and measuring levels of ethiprole and its 
sulfones metabolite have been developed and validated in/on all 
appropriate plant and animal matrices. For plants, extraction using 
acetonitrile/water (9/1, v/v) is followed by LC/MS/MS quantification 
Multiple Reaction Monitoring (MRM) mode. The LOQ for enforcement 
purposes is 0.002 mg/kg expressed as parent equivalents in the rice 
matrices and 0.02 mg/kg in tea. For animals, extraction using 80:20 
acetonitrile/deionized water is followed by oxidation with 34 percent 
peracetic acid that converts ethiprole to RPA97973, with quantification 
by gas chromatography/electron capture detection (GC/ECD). The LOQ for 
all animal commodities is 0.01 mg/kg. Contact: Carmen Rodia, (703) 306-

     3. PP 9E7570. (EPA-HQ-OPP-2009-0032). IR-4, IR-4 Project 
Headquarters, 500 College Rd. East, Suite 201 W, Princeton, NJ 08540, 
proposes to establish a tolerance in 40 CFR part 180 for residues of 
the fungicide fluazinam, 3-chloro-N -[3-chloro-2,6-dinitro-4-
(trifluoromethyl) phenyl]-5-(trifluoromethyl)-2-pyridinamine in or on 
carrot, root at 0.8 ppm. An analytical method using gas chromatography 
with electron capture detection (GC-ECD) for the determination of 
fluazinam residues on carrots has been developed and validated. The 
method involves solvent extraction followed by liquid-liquid 
partitioning and concentration prior to a final purification using 
column chromatography. The method has been successfully validated by an 
independent laboratory using peanut nutmeat as the matrix. The LOQ of 
the method is 0.02 ppm in carrot. Contact: Laura Nollen, (703) 305-

     5. PP 8F7449. (EPA-HQ-OPP-2008-0814). Syngenta Crop Protection, 
Inc., PO Box 18300, Greensboro, NC 27419, proposes to establish a 
tolerance in 40 CFR part 180 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 
in or on rice, grain at 0.02 ppm; rice, straw at 0.02 ppm; rice, bran 
at 0.02 ppm; rice, polished at 0.02 ppm; and rice, hulls at 0.1 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 ultraviolet (UV) or mass spectrometry (MS) detections. The LOD 
for each analyte of this method is 1.25 nanograms (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. Contact: Julie Chao, (703) 308-8735;

     6. PP 8F7485. (EPA-HQ-OPP-2009-0279). Bayer CropScience, P.O. Box 
12014, 2 T.W. Alexander Drive, Research Triangle Park, NC 27709, 
proposes to establish a tolerance in 40 CFR part 180 for residues of 
the fungicide prothioconazole and prothioconazole-desthio in or on 
grain, cereal, group 15, except sweet corn, sorghum, and rice at 0.35 
ppm; forage, cereal, group 16, except sweet corn, sorghum, and rice at 
8.0 ppm; stover, cereal, group 16, except sweet corn, sorghum, and rice 
at 10 ppm; hay, cereal, group 16, except sweet corn, sorghum, and rice 
at 7.0 ppm; straw, cereal, group 16, except sweet corn, sorghum, and 
rice at 5.0 ppm; corn, sweet, forage at 7 ppm; corn, sweet, stover at 8 
ppm; and corn, sweet, kernel plus cob with husks removed at 0.02 ppm. 
The analytical method for determining residues of concern in plants 
extracts residues of prothioconazole and JAU6476-desthio and converts 
the prothioconazole to JAU6476-desthio and JAU6476-sulfonic acid. 
Following addition of internal standards the sample extracts are 
analyzed by LC/MS/MS. Radiovalidation and independent laboratory 
validation have shown that the method adequately quantifies 
prothioconazole residues in treated commodities. The analytical method 
for analysis of large animal tissues includes extraction of the 
residues of concern, followed by addition of an internal standard to 
the extract. The extract is then hydrolyzed to release conjugates, 
partitioned and analyzed by LC/MS/MS as prothioconazole, JAU6476-
desthio and JAU6476-4-hydroxy. The method for analysis of milk 
eliminated the initial extraction step in the tissue method. Contact:

     7. PP 9F7529. (EPA-HQ-OPP-2009-0268). BASF Corporation, Research 
Triangle Park, NC 27709, proposes to establish a tolerance in 40 CFR 
part 180 for residues of the fungicide boscalid (BAS 510F); [3-
pyridinecarboxamide, 2-chloro-N-(4'-chloro(1,1'-biphenyl)-2-yl)-] in or 
on alfalfa, forage at 35 ppm; alfalfa, hay at 85 ppm; and citrus, Crop 
group 10 at 2 ppm. In plants, the parent residue is extracted using an 
aqueous organic solvent mixture followed by liquid/liquid partitioning 
and a column clean up. Quantitation is by gas chromatography using gas 
chromatography/mass spectrometry (GC/MS). In livestock the residues are 
extracted with methanol. The extract is treated with enzymes in order 
to release the conjugated glucuronic acid metabolite. The residues are 
then isolated by liquid/liquid partition followed by column 
chromatography. The hydroxylated metabolite is acetylated followed by a 
column clean-up. The parent and acetylated metabolite are quantitated 
by GC with electron capture detection (GC/ECD). Contact: Bryant Crowe,

     3. PP 8F7487. (EPA-HQ-OPP-2009-0278). Bayer CropScience, 2 T.W. 
Alexander Drive, P.O. Box 12014, Research Triangle Park, NC 27709, 
proposes to increase existing tolerances in 40 CFR 180.555 for residues 
of the fungicide trifloxystrobin, benzeneacetic acid, (E,E)-[alpha]-
(methoxyimino)-2-[[[[1-[3- (trifluoromethyl) 
phenyl]ethylidene]amino]oxy]methyl]-methyl ester and the free form of 
its acid metabolite CGA-321113 ((E,E)-methoxyimino-[2-[1-(3-
trifluoromethyl-phenyl)-ethylideneaminooxymethyl]-phenyl]acetic acid in 
or on corn, field, forage from 0.2 ppm to 6.0 ppm; corn, sweet, forage 
from 0.6 ppm to 7.0 ppm; and corn, sweet, stover from 0.25 ppm to 4.0 
ppm. A practical analytical methodology for detecting and measuring 
levels of trifloxystrobin in or on raw agricultural commodities has 
been submitted. The LOD for each analyte of this method is 0.08 ng 
injected, and the LOQ is 0.02 ppm. The method is based on crop specific 
cleanup procedures and determination by gas chromatography with 
nitrogen-phosphorus detection. A newer analytical method employing 
identical solvent mixtures and solvent to matrix ratio (as the first 
method), deuterated internal standards, and LC/MS-MS with an 
electrospray interface, operated in the positive ion mode is available. 
The LOD range from 0.0019 ppm to 0.0034 ppm for corn matrices and the 
limit of quantitation is 0.01 ppm. Contact: Bryant Crowe, (703) 305-

     4. PP 9F7529. (EPA-HQ-OPP-2009-0268). BASF Corporation, Research 
Triangle Park, NC 27709, proposes to increase existing tolerances in 40 
CFR 180.589 for residues of the fungicide boscalid (BAS 510F); 3-
pyridinecarboxamide, 2-chloro-N-(4'-chloro(1,1'-biphenyl)-2-yl) in or 
on fruit, stone, Crop group 12 from 1.7 ppm to 5 ppm. In plants, the 
parent residue is extracted using an aqueous organic solvent mixture 
followed by liquid/liquid partitioning and a column clean up. 
Quantitation is by gas chromatography using gas chromatography/mass 
spectrometry (GC/MS). In livestock the residues are extracted with 
methanol. The extract is treated with enzymes in order to release the 
conjugated glucuronic acid metabolite. The residues are then isolated 
by liquid/liquid partition followed by column chromatography. The 
hydroxylated metabolite is acetylated followed by a column clean-up. 
The parent and acetylated metabolite are quantitated by GC with 
electron capture detection (GC/ECD). Contact: Bryant Crowe, (703) 305-
0025; <a href="/cdn-cgi/l/email-protection#4526372a32206b27373c242b31052035246b222a33"><span class="__cf_email__" data-cfemail="fd9e8f928a98d39f8f849c9389bd988d9cd39a928b">[email protected]</span></a>.
     5. PP 9F7556. (EPA-HQ-OPP-2009-0325). Gowan Company, 370 South 
Main St., Yuma, AZ 85364, proposes to amend existing tolerances in 40 
CFR 180.448 for residues of the insecticide hexythiazox, trans-5-(4-
chlorophenyl)-N-cyclohexyl-4-methyl-2-oxothiazolidine-3-carboxamide and 
its metabolites containing the (4-chlorophenyl)-4-methyl-2-oxo-3-
thiazolidine moiety in or on grape from 0.75 ppm to 1.0 ppm; plum from 
0.10 ppm to 1.0 ppm; and the processed commodity plum, prune, dried 
from 0.40 ppm to 1.0 ppm. A practical analytical method, high pressure 
liquid chromatography with an ultraviolet detector, which detects and 
measures residues of hexythiazox and its metabolites as a common 
moiety, is available for enforcement purposes with a limit of detection 
that allows monitoring of food with residues at or above the levels set 
in these tolerances. Contact: Olga Odiott, (703) 308-9369;

New Tolerance Exemption

     PP 9E7572. (EPA-HQ-OPP-2009-0043). Joint Inerts Task Force, 
Cluster Support Team 11, EPA Co. No. 84944, c/o CropLife America, 1156 
15th St., NW., Suite 400, Washington, DC 20005, proposes to establish 
an exemption from the requirement of a tolerance under 40 CFR 180.910 
for residues of sodium and ammonium naphthalenesulfonate formaldehyde 
condensates, including: CAS Reg. Nos. 68425-94-5 (residues, petroleum, 
catalytic reformer fractionator, sulfonated, polymers with 
formaldehyde, sodium salts), 9069-80-1 (naphthalenesulfonic acid, 
ammonium salt polymer with formaldehyde), 9084-06-4 
(naphthalenesulfonic acid, polymer with formaldehyde, sodium salt), 
36290-04-7 (2-naphthalenesulfonic acid, polymer with formaldehyde, 
sodium salt), 91078-68-1 (naphthalenesulfonic acids, reaction products 
with formaldehyde, sodium salts), 141959-43-5 (naphthalenesulfonic 
acid, methyl-sodium salt with formaldehyde), and 9008-63-3 
(naphthalenesulfonic acid, sodium salt polymer with formaldehyde) when 
used as pesticide inert ingredients in pesticide formulations. Because 
this petition is a request for an exemption from the requirement of a 
tolerance, no analytical method is required. Contact: Elizabeth
