III. What Action is the Agency Taking?

    EPA is printing notice of the filing of pesticide petitions 
received 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 180 for residues of pesticide chemicals in 
or on various food commodities. EPA has determined that the pesticide 
petitions described in this notice contain data or information 
regarding the elements set forth in section 408(d)(2) of FFDCA; 
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 rules on these 
pesticide petitions.
    Pursuant to 40 CFR 180.7(f), a summary of each of the petitions 
included in 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.

New Tolerances

    1. PP 5F6904. (Docket ID number EPA-HQ-OPP-2005-0157). ABERCO, 
Inc., 9430 Lanham-Severn Road, Seabrook, MD 20706, proposes to 
establish a tolerance for residues of the fungicide propylene oxide in 
or on food commodities: Grape, raisin at 1.0 parts per million (ppm); 
fig at 3.0 ppm and plum, prune, dried at 2.0 ppm. ABERCO has submitted 
an enforcement method for determination of residues of propylene oxide, 
propylene chlorohydrin, and propylene bromohydrin in nutmeats, cocoa, 
and dried spices. Contact: Tony Kish, telephone number: (703) 308-9943; 
e-mail address: [email protected].
    2. PP 6E7144. (Docket ID number EPA-HQ-OPP-2007-0020). Tamico, 
Inc., 1950 Lake Park Dr., Smyrna, GA 30080, proposes to establish 
import tolerances for residues of the fungicide thiram in or on food 
commodities: Banana, whole at 0.5 ppm and banana, pulp at 0.3 ppm. 
Banana samples were analyzed according to analytical method meth-100, 
revision 4 , ``Determination of Thiram in Raw Agricultural 
Commodities, Processed Commodities and Other Plant Material''. 
Detection and quantitation for thiram (as CS2) were conducted using gas 
chromatography (GC) employing sulfur-specific flame photometric 
detection (FPD). The limit of quantitation (LOQ) was 0.05 ppm. Contact: 
Bryant Crowe, telephone number: (703) 305-0025; e-mail address: 
[email protected].
    3. PP 6F7134. (Docket ID number EPA-HQ-OPP-2007-0178). Bayer 
CropScience, P.O. Box 12014, 2 T.W. Alexander Dr., Research Triangle 
Park, NC 27709, proposes to establish a tolerance for residues of the 
fungicide prothioconazole and its desthio metabolite in or on food 
commodities: Beet, sugar, roots at 0.25 ppm and beet, sugar, tops at 
9.0 ppm. The analytical method for determining residues of concern in 
plant extract residues of prothioconazole and JAU6476-desthio and 
converts the prothioconazole to JAU6376-desthio and JAU6476-sulfonic 
acid. Following addition of internal standards the sample extracts are 
analyzed by liquid chromatography/tandem mass spectrometry (LC/MS/MS). 
Radiovalidation and independent laboratory validation have shown that 
the method adequately quantifies prothioconazole residues in treated

[[Page 35240]]

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: Bryant Crowe, telephone number: (703) 305-0025; e-mail 
address: [email protected].
    4. PP 6F7145. (Docket ID number EPA-HQ-OPP-2007-0193). FMC 
Corporation, 1735 Market St., Philadelphia, PA 19203, proposes to 
establish a tolerance for residues of the herbicide carfentrazone-
ethyl, (ethyl--2-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-
oxo-1H-1,2,4-triazol-1-yl]-4-fluorobenzene-propanoate) and the 
metabolite carfentrazone-ethyl, chloropropionic acid (, 2-dichloro-5-
[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-
4-fluorobenzenepropanoic acid) in or on food commodities: Grain, 
cereal, group 15 (except rice grain and sorghum grain at 0.10 ppm; 
rice, grain at 1.3 ppm; sorghum, grain at 0.25 ppm; grain, cereal, 
stover at 0.80 ppm; grain, cereal, straw at 3.0 ppm; soybean, seed at 
0.10 ppm; barley, flour at 0.80 ppm; barley, bran at 0.80 ppm; millet, 
flour at 0.80 ppm; oat, flour at 0.80 ppm; rice, hulls at 3.5 ppm; rye, 
flour at 0.80 ppm; rye, bran at 0.80 ppm; wheat, bran at 0.80 ppm; 
wheat, flour at 0.80 ppm; wheat, middlings at 0.80 ppm; wheat, shorts 
at 0.80 ppm; wheat, germ at 0.80 ppm; aspirated grain fractions at 1.8 
ppm; hog, meat at 0.10 ppm; hog, meat byproducts at 0.10 ppm; hog, fat 
at 0.10 ppm; poultry, meat byproducts at 0.10 ppm; and sugarcane at 
0.15 ppm. The analytical method involves separate analyses for parent 
and its metabolites. The parent is analyzed by GC/electron capture 
detection (ECD). The metabolites are derivatized with boron trifluoride 
and acetic anhydride for analysis by GC/mass spectrometry detection 
(MSD) using selective ion monitoring. Contact: Joanne I. Miller, 
telephone number: (703) 305-6224; e-mail address:

    5. PP 6E7132 and 6E7133. (Docket ID number EPA-HQ-OPP-2007-0300). 
Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for residues of the insecticide Z-cypermethrin, (S-cyano(3-
phenoxyphenyl) methyl ())(cis-trans 3-(2,2-
dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate and its inactive 
R-isomers in or on food commodities: PP 6E7132 - Rice, wild, grain at 
1.50 ppm; okra at 0.20 ppm; safflower, seed at 0.20 ppm; and PP 6E7133 
- Fruit, citrus, group 10 at 0.25 ppm; citrus, dried, pulp at 0.50 ppm; 
and citrus, oil at 0.90 ppm. There is a practical analytical method for 
detecting and measuring levels of cypermethrin in or on food with a 
limit of detection (LOD) that allows monitoring of food with residues 
at or above the levels set in these tolerances (GC/ECD). Contact: 
Sidney Jackson, telephone number: (703) 305-7610; e-mail address: 
[email protected].
    6. PP 6E7153. (Docket ID number EPA-HQ-OPP-2007-0301). 
Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for residues of the herbicide chlorimuron-ethyl [ethyl 2-
[[[[(4-chloro-6-methoxypyrimidin-2yl) amino]carbonyl] amino]sulfonyl] 
benzoate] in or on food commodities: Cranberry; bearberry; bilberry; 
lowbush berry; cloudberry; lingonberry; muntries; and partridgeberry at 
0.02 ppm. The nature of residues of chlorimuron-ethyl is adequately 
understood and an acceptable analytical method is available for 
enforcement purposes. The LOQ allows monitoring of crops with 
chlorimuron-ethyl residues at or above the levels proposed in this 
tolerance. Contact: Sidney Jackson, telephone number: (703) 305-7610; 
e-mail address: [email protected].
    7. PP 6E7167. (Docket ID number EPA-HQ-OPP-2007-0302. Interregional 
Research Project Number 4 (IR-4), 500 College Road East, Suite 201 W, 
Princeton, NJ 08540-6635, proposes to establish a tolerance for 
residues of the miticide bifenazate, (1-methylethyl 2-(4-methoxy[1,1'-
biphenyl]-3-yl)hydrazinecarboxylate) and diazinecarboxylic acid, 2-(4-
methoxy-[1,1'-biphenyl]-3-yl), 1-methylethyl ester (expressed as 
bifenazate) in or on food commodities: Papaya, star apple, black 
sapote, mango, sapodilla, canistel, and mamey sapote at 6.0 ppm; 
lychee, longan, Spanish lime, rambutan, and pulasan at 4.0 ppm; feijoa, 
guava, jaboticaba, wax jambu, starfruit, passionfruit, and acerola at 
0.9 ppm; caneberry subgroup 13A at 6.0 ppm; wild raspberry at 6.0 ppm; 
edible podded legume vegetable, subgroup 6A at 4.0 ppm; succulent 
shelled pea and bean, subgroup 6B at 0.3 ppm; and succulent shelled 
soybean at 0.3 ppm. As D3598, a significant metabolite, was found to 
interconvert readily to/from bifenazate, the analytical method is 
designed to convert all residues of D3598 to the parent compound 
(bifenazate) for analysis. The method utilizes reversed phase high 
performance liquid chromatography (HPLC) to separate the bifenazate 
from matrix derived interferences, and oxidative coulometric 
electrochemical detection for the identification and quantification of 
this analyte. Using this method, the LOQ was 0.05 ppm. The LOD for this 
method, which varies with matrix, is 0.005 ppm. The analytical method 
for bifenazate and its major metabolite D3598 in animal samples used 
the same principles as the plant method with minor modifications. 
However, in animal samples, a separate aliquot of the extract was used 
to determine residues of A1530 and its sulfate (combined) in milk and 
meat samples (these metabolites appeared to be significant in goat 
metabolism studies). The extract was subjected to acid hydrolysis to 
convert the sulfate conjugate to A1530 before it was quantified by HPLC 
using fluorescence or oxidative coulometric electrochemical detectors 
(OCED). Contact: Sidney Jackson, telephone number: (703) 305-7610; e-
mail address: [email protected].
    8. PP 7E7187. (Docket ID number EPA-HQ-OPP-2007-0303). 
Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for residues of the fungicide fenhexamid, (N-2,3-dichloro-4-
hydroxyphenyl)-1-methyl cyclohexene carboxamide) in or on food 
commodity asparagus at 0.02 ppm. An adequate method for purposes of 
enforcement of the proposed fenhexamid tolerance in plant commodities 
is available. Contact: Sidney Jackson, telephone number: (703) 305-
7610; e-mail address: [email protected].
    9. PP 6E7151. (Docket ID number EPA-HQ-OPP-2007-0308). 
Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
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 food commodities: 
Bushberry, subgroup 13B at 0.02 ppm; asparagus, aronia berry, buffalo 
currant, Chilean guava, European barberry, highbush cranberry, 
honeysuckle, jostaberry, Juneberry, lingonberry, Native currant, salal, 
sea buckthorn, and okra at 0.02 ppm; melon, subgroup 9A at 0.02 ppm; 
dry beans at 0.10 ppm; vegetable, fruiting, crop group 8 at 0.02 ppm; 
and nut, tree, crop group 14 at 0.02 ppm. Practical analytical methods 
for detecting and

[[Page 35241]]

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: Sidney Jackson, telephone number: (703) 305-7610;

    10. PP 6E7150. (Docket ID number EPA-HQ-OPP-2007-0309). 
Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for residues of the insecticide etoxazole, (2-(2,6-
difluorophenyl)-4-[4-(1,1-dimethylethyl)-2-ethoxyphenyl]-4,5-
dihydrooxazole) in or on food commodities: hop, dried cones at 7.0 ppm; 
melon, subgroup 9A at 0.15 ppm; and cherry at 0.70 ppm. Practical 
analytical methods for detecting and measuring levels of etoxazole have 
been developed and validated in/on all appropriate agricultural 
commodities and respective processing fractions. The LOQ of etoxazole 
in the methods is 0.02 ppm which will allow monitoring of food with 
residues at the levels proposed for the tolerances. Contact: Sidney

Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for residues of the fungicide tebuconazole, (alpha-[2-(4-
chlorophenyl)-ethyl]-alpha-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-
ethanol) in or on food commodities: Vegetable, bulb, group 3 at 1.3 
ppm; Brassica, leafy greens, subgroup 5B at 2.5 ppm; beet, garden, 
roots at 0.7 ppm; and beet, garden, leaves at 5.0 ppm. An enforcement 
method for plant commodities has been validated on various commodities. 
It has undergone successful EPA validation and has been submitted for 
inclusion in the Pesticide Analytical Manual, Volume II (PAM II). The 
animal method has also been approved as an adequate enforcement method.

Interregional Research Project Number 4 (IR-4), 500 College Road East, 
Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for residues of the fungicide triflumizole, (1-(1-((4-chloro-
2-(trifluoromethyl) phenyl)imino)-2-propoxyethyl)-1H-imidazole), and 
its metabolites containing the 4-chloro-2-trifluoromethylaniline 
moiety, calculated as the parent compound in or on food commodity leafy 
Brassica (subgroup 5B) at 20.0 ppm. The analytical method is suitable 
for analyzing crops for residues of triflumizole and its aniline 
containing metabolites at the proposed tolerance levels. The analytical 
method has been independently validated. Residue levels of triflumizole 
are converted to FA-1-1 by acidic and alkaline reflux, followed by 
distillation. Residues are then extracted and subjected to solid phase 
extraction (SPE) purification. Detection and quantitation are conducted 
by a GC equipped with nitrogen phosphorus detector, electron capture 
detector or mass spectrometry detection. The LOQ of the method has been 
determined at 0.05 ppm for the combined residues of triflumizole and 
FA-1-1 in mustard greens. The enforcement methodology has been 
submitted to the Food and Drug Administration (FDA) for publication in 
the PAM II. Contact: Sidney Jackson, telephone number: (703) 305-7610;

Suite 201 W, Princeton, NJ 08540-6635, proposes to establish a 
tolerance for combined residues of the insecticide flonicamid [N-
(cyanomethyl)-4-(trifluoromethyl)-3-pyridinecarboxamide] and its 
metabolites TFNA [4-trifluoromethylnicotinic acid], TFNA-AM [4-
trifluoromethylnicotinamide], TFNG [N-(4-
trifluoromethylnicotinoyl)glycine] in or on food commodities: 
Vegetables, root, except sugarbeet, (subgroup 1B) at 0.45 ppm; radish, 
tops at 16.0 ppm; vegetables, tuberous and corm, (subgroup 1C) at 0.2 
ppm; Brassica, leafy greens (subgroup 5B) at 16.0 ppm; turnip greens at 
16.0 ppm; hop at 7.0 ppm; and okra at 0.4 ppm. Analytical methodology 
has been developed to determine the residues of flonicamid and its 
three major metabolites (TFNA, TFNG, and TFNA-AM) in various crops. The 
residue analytical method for the majority of crops includes an initial 
extraction with acetonitrile/deionized water (ACN/DI), followed by a 
liquid/liquid partition with ethyl acetate. The residue method for 
wheat straw is similar, except that a C18 solid phase extraction (SPE) 
is added prior to the liquid/liquid partition. The final sample 
solution is quantitated using LC equipped with a reverse phase column 
and a triple quadruple mass spectrometer (MS/MS). Contact: Sidney 
Jackson, telephone number: (703) 305-7610; [email protected].

Triangle Park, NC 27709, proposes to establish a tolerance for residues 
of the fungicide Boscalid (BAS 510F), [3-pyridinecarboxamide, 2-chloro-
N-(4'-chloro(1,1'-biphenyl)-2-yl] in or on food commodities: Cotton, 
undelinted seed at 1.0 ppm and cotton, gin byproducts at 55.0 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 GC using 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 ECD. Contact: Bryant Crowe, telephone number:
