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 a typical 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. PPs 2E6426 and 9E7625. (EPA-HQ-OPP-2009-0843). The Interregional Research Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ 08540, proposes to establish a tolerance in 40 CFR part 180 for residues of the herbicide linuron, (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea), and its metabolites convertible to 3,4-dichloroaniline, calculated as linuron, in or on pea, dry at 0.07 parts per million (ppm); parsley, leaves at 2.5 ppm; and parsley, dried leaves at 7.0 ppm for PP 9E7625; and horseradish at 0.050 ppm for PP 2E6426. Adequate enforcement methods are available for the determination of linuron in plant and animal commodities. The Pesticide Analytical Manual (PAM) Vol. II, lists a colorimetric method (Method I, Bleidner et. al.,) and a paper chromatographic method (Method II). Residues of diuron may interfere in Method I. A modified version of Method I, which includes a cellulose column step to separate linuron from diuron, is currently the preferred method for the enforcement of tolerances. Both of these methods determine linuron and all metabolites hydrolyzable to 3,4-dichloroaniline and have limits of detection of 0.05 ppm. Contact: Laura Nollen, [phone]; [e-mail].

2. PP 9E7573. (EPA-HQ-OPP-2009-0823). Syngenta Crop Protection, Inc., P.O. Box 18300, Greensboro, NC 27419, proposes to establish a tolerance in 40 CFR part 180 for residues of the fungicide difenoconazole, 1-[2-[2-chloro-4-(4-chlorophenoxy)phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl]-1H-1,2,4-triazole, in or on mango at 0.09 parts per million (ppm) and waxapple at 1.5 ppm. The practical analytical method (AG-575B) was submitted for detecting and measuring levels of difenoconazole in or on food with a limit of quantification (LOQ) that allows monitoring of food with residues at or above the levels set in the proposed tolerances. Method REM 147.08 is also available for enforcement method, for the determination of residues of difenoconazole in crops. Residues are qualified by liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS). Contact: Rosemary Kearns, [phone]; [e-mail].

3. PP 9E7577. (EPA-HQ-OPP-2009-0797).

Indaziflam residues are quantified in raw agricultural commodities by high pressure liquid chromatography/triple stage quadrupole mass spectrometry (LC/MS/MS) using the stable isotopically labeled analytes as internal standards. The LOQ of each analyte was 0.005 ppm for all commodities. Contact: Beth Benbow, [phone]; [e-mail].

5. PP 9E7604. (EPA-HQ-OPP-2009-0813). Interregional Research Project No. 4, 500 College Road East, Suite 201W, Princeton, NJ, 08540-6635, in cooperation with Bayer CropScience, Research Triangle Park, NC 27709, proposes to establish a tolerance in 40 CFR part 180 for residues of the herbicide glufosinate-ammonium (butanoic acid, 2-amino-4-(hydroxymethylphosphinyl)-monoammonium salt) and its metabolites, 2-acetamido-4-methylphosphinico-butanoic acid and 3-methylphosphinico-propionic acid, expressed as 2-amino-4-(hydroxymethylphosphinyl)butanoic acid equivalents, in or on corn, sweet, kernel plus cob with husks removed at 0.2 ppm; corn, sweet, forage at 4.0 ppm; and corn, sweet, stover at 6.0 ppm. The enforcement analytical method utilizes gas chromatography for detecting and measuring levels of glufosinate-ammonium and its metabolites with a general limit of quantification of 0.05 ppm. This method allows detection of residues at or above the proposed tolerances. Contact: Sidney Jackson, [phone]; [e-mail].

6. PP 9E7607. (EPA-HQ-OPP-2009-0814). The Interregional Research Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ 08540, in cooperation with Syngenta Crop Protection, Inc., 410 Swing Rd., Greensboro, NC 27419, proposes to establish a tolerance in 40 CFR part 180 for residues of the herbicide, S-metolachlor,S-2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide, its R-enantiomer, and its metabolites, determined as the derivatives, 2-[(2-ethyl-6-methylphenyl)amino]-1-propanol and 4-(2-ethyl-6-methylphenyl)-2-hydroxy-5-methyl-3-morpholinone, each expressed as the parent compound, in or on carrot at 0.3 ppm; cucumber, okra, sesame seed, and sorghum sweet, at 0.1 ppm; Brassica, leafy greens, subgroup 5B, and turnip, greens at 1.2 ppm; melon, subgroup 9A, and caneberry, subgroup 13-07A at 0.08 ppm; blueberry, lowbush at 1.4 ppm; bushberry, subgroup 13-07B at 0.15 ppm; onion, bulb, subgroup 3-07A at 0.1 ppm; and onion, green, subgroup 3-07B at 2.0 ppm. The Pesticide Analytical Manual (PAM) Vol. II, Pesticide Regulation 180.368 lists a GC/NPD method (Method 1) for determining residues in/on plants and a gas chromatography/mass spectrum detector (GC/MSD) method for determining residues in livestock commodities. These methods determine residues of S-metolachlor and its metabolites as either CGA-37913 or CGA-49751 following acid hydrolysis. The LOQ for the method is 0.03 ppm for CGA-37913 and 0.05 ppm for CGA-49751. Syngenta has also developed a chiral specific analytical method to allow for the determination of residues that are specific to S-metolachlor. It is this chiral specific method that Syngenta and IR-4 proposes for future use as the analytical enforcement method in support of these requested tolerances. Syngenta No. 1848-01 was used in several of the studies in this petition to analyze agricultural commodities. The latter chiral specific method is the same as the updated tolerance enforcement method, except that chiral chromatography and LC/MS/MS are used to separate and quantitate the hydrolysis products SYN-506357 (s-configured enantiomer of CGA-37913) and SYN-508500 (s-configured enantiomer of CGA-49751).

8. PP 9E7612. (EPA-HQ-OPP-2009-0775). The Interregional Research Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ 08540, proposes to establish a tolerance in 40 CFR part 180 for residues of the fungicide flutolanil, N-(3-(1-methylethoxy)phenyl)-2-(trifluoromethyl)benzamide and its metabolites converted to 2-(trifluoromethyl) benzoic acid and calculated as flutolanil in or on ginseng at 3.5 ppm; vegetable, Brassica, leafy, group 5 at 0.11 ppm; and turnip, greens at 0.11 ppm. Residues of flutolanil and M-4 are extracted from macerated samples with acetone or a mixture of methanol and water. For cabbage and ginseng, an aliquot of the extract is diluted with water and analyzed using high performance liquid chromatography-mass spectrometry/mass spectrometry (HPLC-MS/MS). For broccoli and mustard greens, the acetone extract is diluted with water and the residues are partitioned into a mixture of ethyl acetate and dichloromethane. This solvent is dispelled and the residue is reconstituted in acetone for purification through Florisil. The purified eluent is taken to dryness and the residues are reconstituted in a mixture of acetonitrile and water. Residues of flutolanil and M-4 are chromatographed and quantified using an HPLC-MS/MS. The LOQ is 0.05 ppm for each flutolanil and M-4. Contact: Laura Nollen, [phone]; [e-mail].

Syngenta Crop Protection, Inc., PO Box 18300, Greensboro, NC 27419-8300, proposes to establish a tolerance in 40 CFR part 180 for residues of the herbicide fluazifop-p-butyl in or on banana and plantains at 0.01 ppm; citrus (whole fruit), citrus (oil), and citrus (juice) at 0.05 ppm; citrus (dried pulp) at 0.40 ppm; grapes at 0.01 ppm; sugarbeet (root) at 0.25 ppm; sugarbeet (top) at 1.5 ppm; sugarbeet (dried pulp) at 1.0 ppm; and sugarbeet (molasses) at 3.5 ppm. Syngenta has developed and validated analytical methodology for enforcement purposes. This method has been submitted to the Agency and is in PAM Vol. II, Method II. An extensive database of method validation data using this method on various crop commodities is available. Contact: Michael Walsh, [phone]; [e-mail].

Amended Tolerances

1. PP 9E7598. (EPA-HQ-OPP-2009-0812). The Interregional Research Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ 08540, in cooperation with Arysta LifeScience North America LLC., 15401 Weston Parkway, Suite 150, Cary, NC 27513, proposes to amend the tolerances in 40 CFR part 180.599 by revising the tolerance expression to read tolerances are established for the residues of the insecticide acequinocyl, including its metabolites and degradates. Compliance with the tolerance levels specified is to be determined by measuring only the sum of acequinocyl, 2-(acetyloxy)-3-dodecyl-1,4-naphthalenedione, and its metabolite, 2-dodecyl-3-hydroxy-1,4-napthoquinone, calculated as the stoichiometric equivalent of acequinocyl and by establishing a tolerance for the residues of acequinocyl, including its metabolites and degradates in or on vegetables, fruiting, group 8 at 0.7 ppm; okra at 0.7 ppm; bean, edible podded at 0.25 ppm; and hop, dried cones at 3.5 ppm. The analytical method to quantitated residues of acequinocyl and acequinocyl-OH in/on fruit crops utilizes high pressure liquid chromatography-mass spectrometry (HPLC/MS/MS) detection for fruiting vegetables; crop group 8 (tomatoes and peppers) and LC/MS/MS for snap-bean; edible podded; and hop; dried cones. The lowest level for method validation (LLMV) was 0.01 ppm for acequinocyl and 0.025 ppm for acequinocyl-OH. Contact: Sidney Jackson, [phone]; [e-mail].

2. PP 9E7625. (EPA-HQ-OPP-2009-0843). The Interregional Research Project No. 4 (IR-4), 500 College Road East, Suite 201W, Princeton, NJ 08540, proposes to amend the tolerance in 40 CFR 180.184(c) by deleting the regional tolerance for residues of the herbicide linuron, (3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea) and its metabolites convertible to 3,4-dichloroaniline, calculated as linuron, in or on parsley, leaves at 0.25 ppm. Contact: Laura Nollen, [phone]; [e-mail].

3. PP 9F7576. (EPA-HQ-OPP-2009-0673). BASF Corporation, 26 Davis Dr., Research Triangle Park, NC 27709, proposes to amend by increasing the tolerance in 40 CFR 180.361 for the combined residues of the herbicide pendimethalin, N-(1-ethylpropyl)-3,4-dimethyl-2,6-dinitrobenzenamine, and its metabolite 4-[(1-ethylpropyl)amino]-2-methyl-3,5-dinitrobenzyl alcohol in or on alfalfa forage to 3.5 ppm. In plants, the method is aqueous organic solvent extraction, column clean-up, and quantitation by gas chromatograph (GC). The method has a LOQ of 0.05 ppm for pendimethalin and the alcohol metabolite. Contact: Philip V. Errico, [phone]; [e-mail].

New Tolerance Exemptions

1. PP 9E7580. (EPA-HQ-OPP-2009-0692). Bayer CropScience, 2 T.W., Alexander Dr., P.O. Box 12014, Research Triangle Park, NC 27709, proposes to establish an exemption from the requirement of a tolerance for residues of α-isotridecyl-ω-methoxy-poly(oxy-1,2-ethanediyl) (CAS No. 345642-79-7) when used as a pesticide inert ingredient surfactant in pesticide formulations under 40 CFR 180.920 in or on all raw agricultural commodities. Since the petitioner is requesting a tolerance exemption, an analytical method for residues of the inert in food crops in not required. Contact: Deirdre Sunderland, [phone]; [e-mail].

2. PP 9E7634. (EPA-HQ-OPP-2009-0845). Wacker Chemical Corporation, 3301 Sutton Rd., Adrian, MI 49221-9397, proposes to establish an exemption from the requirement of a tolerance for residues of tetraethoxysilane, polymer with hexamethyldisiloxane with a minimum number average molecule weight (in AMU) of 2,500 (CAS No. 104133-09-7) in or on all raw agricultural commodities when used as a pesticide inert ingredient in pesticide formulations. Since the petitioner is requesting a tolerance exemption, an analytical method for residues of the inert in food crops in not required. Contact: Deirdre Sunderland, [phone]; [e-mail].
