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 forPP 9E7625; and horseradish at 0.050 ppm forPP 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, (703) 305-7390;email@example.com.
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, (703) 305-5611;firstname.lastname@example.org.

The LOQ of each analyte was 0.005 ppm for all commodities. Contact: Beth Benbow, (703) 347-8072;firstname.lastname@example.org.
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, (703) 305-7610;email@example.com.
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).
