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 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 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.

spectrometry (HPLC/MS/MS) method that employs the use of internal 
standards has been developed and validated for quantification of BYH 
18636 analyte residues in plant matrices. The analytical method was 
developed for the determination of the residues of BYH18636 (parent), 
and its metabolites BYH18636-MMT-glucoside and -N-desmethyl in/on plant 
materials. The calculated limit of detection (LOD) ranges from 0.001 to 
0.003 ppm. The limit of quantitation (LOQ) for this method is 0.01 ppm 
for each analyte in plant matrices. Contact: Hope A. Johnson, (703) 
305-5410, johnson.hope@epa.gov.
    5. PP 7F7260. (EPA-HQ-OPP-2008-0168). BASF Corporation, P.O. Box 
13528, Research Triangle Park, NC 27709, proposes to establish a 
tolerance for residues of the insecticide metaflumizone in or on food 
commodities grape at 0.01 ppm; citrus fruits group (crop group 10) at 
0.01 ppm; and tree nuts group (crop group 14) at 0.01 ppm. BASF 
Analytical Method No. 531/0 was developed to determine residues of 
metaflumizone and its metabolites M320I04 and M320I23, the residues of 
concern in plants, and in crop matrices. In this method, residues of 
metaflumizone are extracted from plant matrices with methanol/water 
(70:30; v/v) and then partitioned into dichloromethane. For oily 
matrices, the residues are extracted with a mixture of isohexane/
acetonitrile (1:1; v/v). The final determination of metaflumizone and 
its metabolites is performed by liquid chromatography/mass spectrometry 
(LC/MS/MS). Contact: Julie Chao, (703) 308-8735, chao.julie@epa.gov.
    6. PP 7F7293. (EPA-HQ-OPP-2008-0167). Syngenta Crop Protection 
Inc., P.O. Box 18300, Greensboro, NC 27419-8300, proposes to establish 
a tolerance for residues of insecticide thiamethoxam {3-[(2-chloro-5-
thiazolyl)methyl]tetrahydro-5-methyl-N-nitro-4H-1,3,5-oxadiazin-4-
imine{time} (CAS Reg. No. 153719-23-4) and its metabolite [N-(2-chloro-
thiazol-5-ylmethyl)-N'-methyl-N'-nitro-guanidine] in or on food 
commodities fruit, citrus (Crop Group 10) at 0.3 ppm; and nut, tree 
(Crop Group 14) including pistachio at 0.3 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 limit of 
detection (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 limit of quantification (LOQ) is 0.005 ppm for milk and juices, 
and 0.01 ppm for all other substrates. Contact: Julie Chao, (703) 308-
8735, chao.julie@epa.gov.
    7. PP 8F7328. (EPA-HQ-OPP-2008-0217). Bayer CropScience, 2 T.W. 
Alexander Drive, Research Triangle Park, NC 27709, proposes to 
establish a tolerance for residues of the herbicide isoxaflutole 5-
cyclopropyl-4-(2-methylsulfonyl-4-trifluoromethylbenzoyl) isoxazole and 
its metabolite 1-(2-methylsulphonyl-4-trifluoromethylphenyl)-2-cyano-3-
cyclopropyl propane-1,3-dione (RPA 202248), calculated as the parent 
compound in or on food commodities corn, field, grain corn at 0.02 ppm; 
corn, field, forage at 0.02 ppm; and corn, field, stover at 0.02 ppm. A 
practical analytical method has been developed for detecting and 
quantifying levels of Isoxaflutole and RPA 202248 in or on raw 
agricultural commodities obtained from field corn. This method allows 
monitoring of these commodities with residues at or above the levels 
proposed in this petition. Quantitation of analytes as individual 
components is performed by daughter-ion detection using liquid 
chromatography/mass spectroscopy (LC/MS/MS). The limit of quantitation 
(LOQ) for all analytes is 0.01 ppm. The proposed analytical enforcement 
method to determine isoxaflutole-derived residues in plants has been 
validated by an independent laboratory. Contact: Erik Kraft, (703) 308-
9358, kraft.erik@epa.gov.
