This document was originally prepared under contract by Dynamac Corporation ( 1910 Sedwick Rd., Building 100, Suite B; Durham, NC 27713; submitted 25 OCT 2005). The document has been reviewed by the HED and revised to reflect current OPP policies.

Executive Summary Bifenthrin ( 2 methyl[ 1,1' biphenyl] 3 yl) methyl 3( 2 chloro 3,3,3 trifluoro 1 propenyl) 2,2 dimethyl cyclopropanecarboxylate) is a synthetic pyrethroid that is currently used for control of insects on a variety of fruit, vegetable and field crops. Permanent tolerances are established for residues of bifenthrin in/ on plant and livestock commodities at levels ranging from 0.05 ppm ( limit of quantitation ( LOQ)) on various commodities to 10.0 ppm in/ on dried hop cones [ 40 CFR § 180.442( a)].

The Interregional Research Project No. 4 ( IR 4) has submitted a series of petitions ( PP# s: 2E6451, 2E6423, 3E6882 and 4E6843) proposing the use of bifenthrin, formulated as a 2 lb/ gal Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 2 of 21 emulsifiable concentrate ( EC) or a 1.15% granule ( G), on tuberous and corm vegetables, Brassica leafy greens, dried shelled peas and beans ( except soybeans), and cilantro. The proposed use for tuberous and corm vegetables includes an at planting application of the EC or G formulations at 0.3 lb ai/ A, followed by up to two foliar applications of the EC formulation at 0.1 lb ai/ A/ application, with a retreatment interval ( RTI) of 21 days and a 21 day pre harvest interval ( PHI). The uses on Brassica leafy greens, dried peas and beans, and cilantro ( coriander) are for 2 to 5 broadcast foliar applications of the EC formulation at 0.1 lb ai/ A/ application, with a RTI of 7 days ( when specified) and PHIs of 3 14 days. In conjunction with these uses, IR 4 is proposing tolerances for residues on tuberous and corm vegetables ( subgroup 1C) at 0.1 ppm, Brassica leafy greens ( subgroup 5B) at 3.0 ppm, dried shelled pea and bean, except soybean, ( subgroup 6C) at 0.1 ppm, cilantro leaves and seed at 5.0 ppm, and cilantro dried leaves at 30.0 ppm. FMC Corporation is also requesting a label amendment for its EC formulation allowing use of bifenthrin on tobacco as a pre plant or at transplanting application at 0.1 lb ai/ A followed by foliar application( s) at 0.05 lb ai/ A/ application.

Based on the previously submitted cotton, corn, apple, hen, and goat metabolism data and the currently submitted potato metabolism study, the nature of bifenthrin residues in plants and livestock is understood. The residue of concern is bifenthrin per se in both primary and rotated crop commodities and in livestock.

Adequate gas chromatography ( GC)/ electron capture detection ( ECD) methods are available for enforcing tolerances of bifenthrin in plant and livestock commodities. The available methods for plant commodities generally involve extraction of the sample with acetone, partitioning with hexane, purification using a Florisil column, and analysis of residues by GC/ ECD. The limit of quantitation ( LOQ) for these methods is 0.05 ppm. Samples from the current field trials and the potato processing study were analyzed using methods that are modifications to one of the current enforcement methods ( P 2550 M), with variations in extraction solvents and detection methods. Residues of bifenthrin in/ on mustard greens and cilantro ( leaves and seeds) were determined using a GC/ ECD method ( FMC Report P 2132). For this method, residues are extracted with hexane, concentrated, and cleaned up using a Florisil column, then analyzed by GC/ ECD. Residues in/ on potato fractions and dried beans and peas were determined using a GC/ mass selective detection ( MSD) method ( FMC Report P 3426). For this method, residues are extracted with acetone, concentrated, and purified by silica gel solid phase extraction ( SPE). The residues are then analyzed by GC/ MSD, using the m/ z 181 ion for quantitation. Residues in/ on green tobacco were determined using a related GC/ MSD method ( FMC Report P 3457). For this method, residues are extracted with acetone/ water, partitioned into hexane, and cleaned up with a SPE column, and analyzed by GC/ MSD. For each of the above methods, the LOQ for bifenthrin is 0.05 ppm, and the reported limit of detection ( LOD) is 0.01 ppm. Each of these methods was adequately validated in conjunction with analysis of samples from the field trials or processing study.

The field trials on potatoes, mustard greens, dried beans and peas, cilantro, and tobacco are adequate. An adequate number of trials were conducted reflecting the proposed use patterns in the appropriate geographic regions, and the appropriate commodities were collected at the proposed PHIs. Samples were analyzed using adequate analytical methods, and the sample storage intervals are supported by the available storage stability data.

Following an at planting soil application and two foliar applications of bifenthrin at 1x the proposed rate, residues were < 0.05 ppm (< LOQ) in/ on all potatoes harvested at 21 days after the Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 3 of 21 final application ( DAT). Residues on mustard greens harvested 6 7 DAT were < 0.05 2.05 ppm following four foliar applications of bifenthrin ( EC) totaling ~ 0.4 lb ai/ A ( 1x). In the dried bean and pea field trials, residues on dried beans harvested 13 15 DAT were < 0.05 0.10 ppm following three foliar applications of bifenthrin ( EC) totaling 0.3 lb ai/ A ( 1x), and residues on dried peas harvested 14 15 DAT were < 0.05 ppm following two foliar applications of bifenthrin ( EC) totaling 0.2 lb ai/ A ( 1x). Following five foliar applications of bifenthrin ( EC) to cilantro totaling ~ 0.5 lb ai/ A ( 1x), residues at 3 DAT were 1.98 4.83 ppm in/ on fresh leaves, 14.93 16.25 ppm in/ on dried leaves, and 3.66 3.69 ppm in/ on seeds. In the tobacco field trials, residues of bifenthrin were < 0.05 ppm in/ on all green tobacco samples harvested at normal maturity following either a preplant or at transplanting application of bifentrhin ( EC or G) at 0.1 lb ai/ A and a single foliar application of bifenthrin ( EC) at 0.05 or 0.10 lb ai/ A ( 1x).

The available potato processing study is adequate. Because bifenthrin residues were < LOQ (< 0.05 ppm) in all samples from the potato field trials and in potato tubers and all processed fractions from the processing study conducted at a 3x rate, HED concludes that residues of bifenthrin in wet peel are unlikely to exceed the LOQ when bifenthrin is applied at a 1x rate. Therefore, a separate tolerance will be not required for residues in/ on processed potato fractions. In addition, a comparison of residues in/ on fresh and dried cilantro leaves indicates that there is a 5.7x processing factor for dried cilantro leaves. Based on highest average field trial ( HAFT) residues of 3.96 ppm in/ on fresh leaves, the maximum expected residues in/ on dried cilantro leaves would be 22.6 ppm.

The proposed tolerances for plant commodities will not have any impact on the current tolerances for livestock commodities. The only proposed crop use with any regulated livestock feedstuffs is potato ( processed potato waste and culls), and the addition of these commodities to livestock diets will not increase the dietary exposure of livestock calculated in the Bifenthrin Tolerance Reassessment Eligibility Decision ( TRED) ( S. Levy, 22 AUG 2002; DP# 283808).

Adequate confined and field rotational crop studies are available to support the proposed uses. Based on the results of these rotational crop studies, HED concludes that the current rotational crop plant back interval is acceptable and that tolerances for rotated crops are not necessary.

Regulatory Recommendations and Residue Chemistry Deficiencies Provided revised Sections B and F are submitted, HED concludes there are no residue chemistry data requirements that would preclude establishing permanent tolerances for residues of bifenthrin per se at 0.05 ppm in/ on tuberous and corm vegetables ( subgroup 1C), 3.5 ppm in/ on leafy Brassica greens ( subgroup 5B), 0.15 ppm in/ on dried shelled pea and beans, except soybean ( subgroup 6C), 5.0 ppm in/ on coriander leaves and seeds, and 25 ppm in/ on coriander dried leaves. Revised Section Fs should be submitted with the correct tolerance level and commodity definitions, where appropriate ( see Table 6). Also, the use directions for dried beans and peas should be amended to specify a minimum RTI of 7 days The available field trial data will also support the use of bifenthrin ( EC) on tobacco, for which tolerances are not required. As residues were < 0.1 ppm in/ on all samples of green tobacco from the field trials, no additional residue data are required on tobacco. However, FMC should amend its use directions for tobacco to specify the maximum number of foliar applications allowed and the maximum seasonal use rate. The available tobacco field trials will support use of the 2 lb/ gal Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 4 of 21 EC as either a broadcast pre plant soil application at up to 0.1 lb ai/ A or an in furrow water drench application at transplant at up to 0.1 lb ai/ A, followed by a single broadcast foliar application up to lay by at up to 0.1 lb ai/ A, for a maximum seasonal use rate of 0.2 lb ai/ A. A revised Section B should be submitted.

A human health risk assessment for bifenthrin will be prepared in a separate document.

Background Bifenthrin is a synthetic pyrethroid insecticide ( MOA Group 3) that is registered to FMC Corporation for control of insects on a variety of fruit, vegetable, and field crops. Tolerances are established for residues of bifenthrin per se in/ on plant and livestock commodities at levels from 0.05 ppm ( LOQ) on various commodities to 10.0 ppm on dried hop cones [ 40 CFR 180.442( a)].

The IR 4 has submitted a series of petitions ( 2E6451, 2E6423, 3E6882 and 4E6843) proposing the use of bifenthrin, formulated as a 2 lb/ gal EC or a 1.15% G, on tuberous and corm vegetables, Brassica leafy greens, dried and shelled peas and beans ( except soybeans), and cilantro. In conjunction with these uses, the petitioner is proposing the following tolerances:

Vegetable, tuberous and corm, subgroup 1C ........................................................... 0.1 ppm Brassica, leafy greens, subgroup 5B ....................................................................... 3.0 ppm Pea and bean, dried shelled, except soybean, subgroup 6C...................................... 0.1 ppm Cilantro, leaves ....................................................................................................... 5.0 ppm Cilantro, dried leaves ............................................................................................ 30.0 ppm Coriander, seed ....................................................................................................... 5.0 ppm In addition, FMC has proposed amending the 2 lb/ gal EC formulation to include uses on tobacco ( non food/ feed).

Conclusions. The proposed use directions for tuberous and corm vegetables, leafy Brassica greens, dried peas and beans, and cilantro are adequately supported by the available field trials on potatoes, mustard greens, dried beans and peas, and cilantro; however, the use directions for dried beans and peas should be amended to specify a minimum RTI of 7 days. The available tobacco field trials will also support the use of the EC formulation on tobacco; however, the use directions should be amended to specify the maximum number of foliar applications allowed and the maximum seasonal use rate. The available tobacco field trails will support use of the 2 lb/ gal EC Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 7 of 21 as either a broadcast pre plant soil application at up to 0.1 lb ai/ A or an in furrow water drench application at transplant at up to 0.1 lb ai/ A, followed by a single broadcast foliar application up to lay by at up to 0.1 lb ai/ A, for a maximum seasonal use rate of 0.2 lb ai/ A. These data will also support the use of the 1.15% G formulation to tobacco as a single broadcast pre plant soil application at up to 0.1 lb ai/ A. A revised Section B should be submitted.

860.1300 Nature of the Residue   Plants.

Bifenthrin TRED, S. Levy, 21 AUG 2002; DP# 283808 45794202. der The nature of bifenthrin residues in plants is adequately understood based on the available metabolism studies on corn, cotton, and apple. HED previously determined that for purposes of tolerance expression and risk assessment, the residue of concern in cotton and apple commodities is bifenthrin per se ( Memos, M. Flood, 24 DEC 1987 and N. Dodd, 02 JUL 1987). After reexamining the cotton and apple metabolism data and additional corn metabolism data, the HED Metabolism Committee ( Memo, M. Flood, 23 JUL 1993) reaffirmed that the residue of concern in plant commodities is bifenthrin per se.

In conjunction with the petition for use on tuberous and corm vegetables, IR 4 has submitted an additional metabolism study on potatoes reflecting both soil and foliar applications of [ 14C] bifenthrin. The potato study is adequate and the results from the metabolism study ( discussed below) support HED's previous determination that the residue of concern is bifenthrin per se.

Potato metabolism. The metabolism of bifenthrin in potatoes was examined in two trials using either [ cyclopropyl 1 14C] or [ U phenyl 14C] labeled bifenthrin ( 14C CP or 14C PH). Each 14Clabel was formulated as an EC and applied to potatoes as a single in furrow application at 0.3 lb ai/ A, followed by two broadcast foliar applications at 0.1 lb ai/ A/ application, for a total of 0.5 lb ai/ A ( 1x rate). The foliar applications were made late in the season during the vegetative stage, at a RTI of 14 days. Samples of potato tubers and foliage were collected at 2 and 14 day PHIs.

The levels of radioactivity in foliage and tubers were similar for the [ 14C CP] and [ 14C PH] labeled samples. Total radioactive residues ( TRR) in foliage were 2.89 3.29 ppm at a 2 day PHI and declined to 1.94 2.70 ppm by the 14 day PHI. TRR were substantially lower in tubers ( 0.020 0.068 ppm) at both sampling intervals, indicating that translocation of [ 14C] bifenthrin from leaves to the tubers was minimal.

Mature ( 14 day PHI) samples of tubers and foliage were extracted with acetonitrile ( ACN), releasing 91 96% of the TRR from each matrix. Solubilized residues were subsequently partitioned into hexane, ether/ ACN, and aqueous fractions. Radioactivity remaining in the residual solids accounted for 7.5 8.6% TRR in tubers and 4.3% of the TRR in foliage. With the exception of several minor metabolites, the 14C residue profiles in tubers and foliage were similar for the two 14C labels, with identified residues accounting for 75 81% of the TRR in tubers and 95% of the TRR in foliage. In all matrices, bifenthrin was the major 14C residue accounting for 73 81 % of the TRR in tubers and 95% of the TRR in foliage. Minor amounts (  1.2% TRR, < 0.001 ppm) of the following metabolites were also tentatively identified by high performance liquid chromatography ( HPLC) in tubers: 4 OH bifenthrin, biphenyl alcohol or acid metabolites, a Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 8 of 21 biphenyl aldehyde metabolite, and TFP acid ( see attachment 2 for structures). No metabolites were detected in foliage. Considering the type of metabolites detected, the metabolism of bifenthrin in potatoes appears to involve hydrolytic cleavage of the ester linkage and hydroxylation of the biphenyl moiety.

860.1300 Nature of the Residue   Livestock.

Bifenthrin TRED, S. Levy, 21 AUG 2002; DP# 283808 Adequate ruminant and poultry metabolism studies are available depicting the metabolism of bifenthrin radiolabeled in either the phenyl or cyclopropyl ring. Based on these data, the HED Metabolism Committee ( M. Flood, 8/ 2/ 93) concluded that the residue of concern in livestock commodities is bifenthrin per se.

860.1340 Residue Analytical Methods  Plants.

Adequate GC/ ECD methods are available for enforcing bifenthrin tolerances on cottonseed ( FMC Method RAN 0140), corn commodities ( FMC Method P 2550), pears ( FMC Method P 0757), and pecans ( FMC Method PC 0130); these methods have undergone successful petition method validation ( PMV) trials. The general procedures of these methods involve extraction of the sample with acetone, partitioning with hexane, purification of the extract by Florisil column chromatography, and analysis of the extract by GC/ ECD. The LOQ for these methods is 0.05 ppm.

Residues of bifenthrin in samples from the current crop field trials and processing study were determined using modifications of FMC method P 2550 M, with variations in extraction solvents and detection methods. Residues of bifenthrin in/ on mustard greens and cilantro ( fresh, dried, seeds) were determined using a GC/ ECD method ( FMC Report P 2132). For this method, residues are extracted with hexane, concentrated, and cleaned up using a Florisil column, then analyzed by GC/ ECD. Residues in/ on potato fractions and dried beans and peas were determined using a GC/ MSD method ( FMC Report P 3426). For this method, residues are extracted with acetone, concentrated, and purified by silica gel SPE. The residues are then analyzed by GC/ MSD, using the m/ z 181 ion for quantitation. Residues in/ on green tobacco were determined using a related GC/ MSD method ( FMC Report P 3457). For this method, residues are extracted with acetone/ water, partitioned into hexane, and cleaned up with a SPE column, and analyzed by GC/ MSD. For each of the above methods, the LOQ for bifenthrin is 0.05 ppm, and the reported LOD is 0.01 ppm.

Each of the above methods was validated in conjunction with the field trials or processing study. For potatoes matrices fortified at 0.05 0.2 ppm, average recoveries were 72 100% with standard deviations of ± 7 12%; for mustard greens fortified at 0.05 6.1 ppm, average recoveries were 73 104%, with standard deviations of ± 2 15%; for fresh cilantro and seed fortified at 0.05 4.9 ppm and dried cilantro fortified at 0.1 20 ppm, average recoveries were 79 92%, with standard deviations of ± 4 15%; and for tobacco fortified at 0.05 ppm, the average recovery was 110 ± 4%. Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 9 of 21 Conclusion. The available GC/ ECD or GC/ MSD methods are adequate for collecting data on bifenthrin residues in/ on mustards greens, dried beans and peas, potato matrices ( tubers, chips, wet peel, and flakes), cilantro leaves ( fresh and dried) and seeds, and green tobacco.

860.1340 Residue Analytical Methods  Livestock.

Several GC/ ECD methods are available for enforcing of tolerances for bifenthrin in cattle tissues and milk ( P 1031) and in poultry tissues ( P 1843M) and eggs ( RAN 0204M). The general procedures of these methods involve extraction of the sample with acetone, purification of the residues by Florisil column chromatography, and analysis of the residues by GC/ ECD. The LOQ for bifenthrin is 0.005 ppm in eggs, and 0.05 ppm in milk and tissues.

860.1360 Multiresidue Methods ( MRM)

The Food and Drug Administration ( FDA) PESTDATA database dated 10/ 99 ( PAM Vol. I, Appendix II) indicates that bifenthrin is completely recovered using MRM Section 303 and that recoveries using Section 302 are variable. No information pertaining to the recovery of bifenthrin using Section 304 is available.

860.1380 Storage Stability.

Bifenthrin TRED, S. Levy, 21 AUG 2002; DP# 283808 Adequate data are available indicating that bifenthrin is stable during frozen storage (  18 ° C) in a variety of plant matrices. Residues of bifenthrin are stable during frozen storage for up to: 12 months in corn flour, meal, oil, and starch; 18 months in/ on oranges ( whole) and orange dried pulp, juice, and oil; 24 months in/ on cottonseed; 34 months in/ on corn grain; 36 months in/ on lettuce, pecans, and potatoes; and 49 months in/ on apple, corn silage, and corn stover.

In the current field trials and potato processing study, the maximum frozen storage intervals were 2 months for mustard greens, dried peas and beans, and whole potatoes,   1 month for processed potato fractions, 8 months for green tobacco, 22 and 23 months for cilantro leaves, fresh and dried, respectively, and 17 months for seeds.

Conclusion. The available storage stability data are adequate to support the sample storage intervals and conditions from the current field trials and potato processing study.

860.1480 Meat, Milk, Poultry, and Eggs Bifenthrin TRED, S. Levy, 21 AUG 2002; DP# 283808 The maximum theoretical dietary burdens ( MTDB) of bifenthrin for livestock were recently calculated in the Bifenthrin TRED. Based on established and recommended tolerances, the MTDB was calculated to be 2.7 ppm for beef cattle, 3.3 ppm for dairy cattle, 0.14 ppm for poultry, and Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 10 of 21 0.12 ppm for hogs. In the current series of petitions, the only crop with any regulated livestock feedstuffs is potato ( processed potato waste and culls). As potato waste and culls are not fed to poultry, the proposed uses will not have any impact on the current tolerances for poultry commodities.

Using a HED recommended tolerance of 0.05 ppm for potato ( tuber and corm vegetable), the MTDB was recalculated for cattle and hogs ( Table 4). The inclusion of potato feedstuffs did not increase the MTDB of beef cattle ( 2.73 ppm), dairy cattle ( 3.33 ppm), or hogs ( 0.12 ppm). Therefore, the proposed uses will not have any impact on the current milk or livestock tolerances.

For calculation of the median, mean, and standard deviation, ½ LOQ was used for samples with residues < LOQ. 2 HAFT = Highest Average Field Trial. 3 The use rate for potatoes reflects the use of either an EC or G formulation applied in furrow at 0.3 lb ai/ A in side by side trials, followed by two foliar applications of an EC at 0.1 lb ai/ A/ application. 4 Four application regimes were used on tobacco: ( 1) a single pre transplant, broadcast application ( EC or G) at 0.1 lb ai/ A; ( 2) a single in furrow or soil drench application ( EC) at transplanting at 0.1 lb ai/ A; an in furrow or soil drench application ( EC) at 0.1 lb ai/ A at transplanting, followed by a single broadcast foliar application ( EC) at 0.05 lb ai/ A, for a total of 0.15 lb ai/ A/ season ; and ( 4) an in furrow or soil drench application ( EC) at 0.1 or 0.2 lb ai/ A at transplanting, followed by a single broadcast foliar application ( EC) at 0.1 lb ai/ A, for a total of 0.2 or 0.3 lb ai/ A/ season .

Potatoes: Twelve potato field trials were conducted during 2001 comparing the use of two bifenthrin formulations. At each trial, bifenthrin ( 2 lb/ gal EC or 1.15% G) was applied to potatoes as one in furrow application at 0.3 lb ai/ A followed by two broadcast foliar applications of the 2 lb/ gal EC at 0.1 lb ai/ A/ application, for a total of 0.5 lb ai/ A/ season ( 1x proposed rate). The infurrow application was made prior to planting, and the foliar applications were made late in the season, approximately 42 and 21 days prior to normal maturity. Duplicate control and treated samples of potatoes were harvested at commercial maturity from treatment at each trial site, at approximately 20 21 day PHIs. Samples were stored frozen for up to 1 month, an interval supported by the available storage stability data.

The GC MSD method ( FMC Report P 3426) used to determine bifenthrin residues in/ on potatoes was adequately validated in conjunction with the field trial analyses. The validated LOQ was 0.05 ppm, and the LOD was 0.01 ppm.

Regardless of the type of formulation used for the in furrow application ( G or EC), bifenthrin residues were < LOQ (< 0.05 ppm) in/ on all 48 samples of potatoes harvested ~ 20 21 DAT following applications at 1x. The average and HAFT residues in/ on potatoes were 0.025 and 0.05 ppm, respectively. Residue decline information could not be determined from the two decline trials because of the lack of residues found at any of the sampling points. Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 12 of 21 Mustard Greens: In eight field trials conducted during 1999, bifenthrin ( 2 lb/ gal EC) was applied as four broadcast foliar applications to mustard greens at 0.097 0.110 lb ai/ A/ application, for a total of 0.397 0.427 lb ai/ A/ season ( 1x the propose rate). Applications were made during vegetative growth, at RTIs of 6 8 days. Duplicate control and treated samples of fresh mustard greens were harvested at commercial maturity from each trial site, at 6 7 day PHIs. Samples were stored frozen for up to 2 months prior to analysis, an interval supported by the available storage stability data.

The GC/ ECD method ( FMC Report P 2132M, modified) used to determine bifenthrin residues in/ on mustard greens was adequately validated in conjunction with the field trial analyses. The validated LOQ was 0.05 ppm. The LOD was not calculated or estimated.

Bifenthrin residues were 0.05 2.05 ppm in/ on 16 samples of mustard greens harvested at 6 7 day PHIs, following applications at 1x the proposed rate. The average and HAFT residues in/ on mustard greens were 1.04 and 2.01 ppm, respectively. Residue decline data were not provided.

Dried Beans and Peas: A total of 15 field trials were conducted during 2001 on dried beans ( 9 trials) and peas ( 6 trials), which are the representative crops for Crop subgroup 6C. Bifenthrin ( 2 lb/ gal EC) was applied to dried beans as three broadcast foliar applications at 0.1 lb ai/ A/ application, for a total of 0.3 lb ai/ A/ season ( 1x proposed rate). The initial application was made at the 2 6 node stage, the second application was made at bloom through pod fill, and the final application was made at early maturity, ~ 14 days prior to normal harvest. The RTIs for dried beans were 10 44 days. In the six dried pea field trials, bifenthrin ( 2 lb / gal EC) was applied as two broadcast foliar applications at 0.1 lb ai/ A/ application, at approximately 21 and 14 days prior to normal maturity, for a total of 0.2 lb ai/ A/ season ( 1x the proposed rate). The RTIs for the dried pea trials were 6 7 days. At commercial maturity ( 13 15 day PHIs), a single control and duplicate treated samples of dried beans or peas were collected from each trial. To examine residue decline, additional duplicate samples were collected at 9, 14, 19, and 27 day PHIs from one dried bean trial and at 12, 15, 20, and 27 day PHIs from one dried pea trial. Samples were stored frozen for up to 2 months, an interval supported by the available storage stability data.

The GC/ MSD method ( FMC Report P 3426) used to determine bifenthrin residues in/ on beans and peas was adequately validated in conjunction with the field trial analyses. The validated LOQ was 0.05 ppm, and the LOD was 0.01 pm.

Following applications at 1x the proposed rate, residues of bifenthrin were < 0.01 0.10 ppm in/ on 18 samples of dried beans harvested 13 15 DAT, and < LOQ in/ on all 12 samples of dried peas (< 0.01 0.02 ppm) harvested at 14 15 DAT. The average residues were 0.043 ppm for dried beans and 0.025 ppm for dried peas. Residue decline could not be determined for dried beans, as residues in all samples from the decline trial were < LOD. However, residues in dried peas, although low (  0.02 ppm), did show decline at longer post treatment intervals.

Cilantro ( Coriander): In four field trials conducted during 2000 2001, bifenthrin ( 2 lb/ gal EC) was applied as five broadcast foliar applications to cilantro at 0.097 0.106 lb ai/ A/ application, for a total of 0.497 0.518 lb ai/ A/ season ( 1x proposed rate). Applications were made beginning at the 1 4 true leaf stage, at RTIs of 6 7 days. At commercial maturity, samples of fresh cilantro foliage ( 3 trials) and seeds ( 1 trial) were harvested 3 DAT. At one of the trial sites, additional samples of fresh cilantro were harvested at 2 DAT and dried in ovens for 2 days to yield dried cilantro Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 13 of 21 samples. Duplicate control and treated samples were collected for analysis from each trial. Samples were stored frozen for up to 23 months, an interval supported by the available stability data.

The GC/ ECD method used to determine bifenthrin residues in/ on cilantro ( FMC Report P 2132M, modified) was adequately validated in conjunction with the field trial analyses. The validated LOQ was 0.05 ppm.

Following applications at 1x rate, bifenthrin residues were 1.98 4.83 ppm in/ on 6 samples of fresh cilantro foliage harvested 3 DAT, 14.93 16.25 ppm in/ on 2 dried cilantro samples harvested 2 DAT, and 3.66 3.69 ppm in/ on 2 cilantro seed samples harvested 3 DAT. The average and HAFT residues in/ on fresh cilantro were 2.97 and 3.96 ppm, respectively. Based on average residues in fresh cilantro ( 2.73 ppm) and dried cilantro ( 15.59 ppm) from one trial, the concentration factor for dried cilantro is 5.7x.

Tobacco ( non food/ feed): Field trials on tobacco were conducted at three trial sites in VA ( 2) and GA ( 1) during 2002, with four different application regimes being tested at each field site. The four application regimes included: ( i) a single pre transplant, broadcast application of either the 2 lb/ gal EC or 1.15% G formulation at 0.1 lb ai/ A ( Plot 1); ( ii) a single in furrow or soil drench application of the 2 lb/ gal EC at transplanting at 0.1 lb ai/ A ( Plot 2); a combination of an in furrow or soil drench application of the 2 lb/ gal EC at 0.1 lb ai/ A at transplanting, followed

1 month later by a single broadcast foliar application of the 2 lb/ gal EC at 0.05 lb ai/ A, for a total of 0.15 lb ai/ A/ season ( Plot 3); and ( iv) a combination of an in furrow or soil drench application of the 2 lb/ gal EC at 0.1 or 0.2 lb ai/ A at transplanting, followed

1 month later by a single broadcast foliar application of the 2 lb/ gal EC at 0.1 lb ai/ A, for a total of 0.2 or 0.3 lb ai/ A/ season ( Plot 4).

For the first VA field trial, tobacco was harvested three times between 90 176 DAT from Plots 1 and 2, and 57 106 DAT from Plots 3 and 4. For the GA field trial, tobacco was also harvested three times between 85 128 DAT from Plots 1 and 2 and 55 98 DAT from Plots 3 and 4. For the second VA field trial, tobacco was harvested only once at 105 or 142 DAT from Plots 1 and 2 and at 72 DAT from Plots 3 and 4. At each harvest interval, a single control and duplicate treated samples of green tobacco were harvested from each trial plot.

Residues of bifenthrin in/ on green tobacco were determined using a GC/ MSD method ( FMC Report P 3457). The method LOQ is 0.05 ppm, and the LOD is 0.01 ppm. Bifenthrin residues were < 0.05 ppm (< LOQ) in/ on all green tobacco samples from each application regime at all harvest intervals.

Conclusions. The field trials on potatoes, mustard greens, dried beans and peas, cilantro, and tobacco are adequate. An adequate number of trials were conducted reflecting the proposed use patterns in the appropriate geographic regions, and the appropriate commodities were collected at the proposed PHIs. Samples were analyzed using adequate analytical methods, and the sample storage intervals are supported by the available storage stability data. The available potato data will support a tolerance of 0.05 ppm on tuberous and corm vegetables ( subgroup 1C), and the mustard green data will support a tolerance of 3.5 ppm on leafy Brassica vegetables ( subgroup 5B). The data on dried beans and peas will support a tolerance of 0.15 ppm on shelled dried beans and peas, excluding soybean ( subgroup 6C). The data on cilantro ( coriander) will support separate tolerances of 5 ppm in/ on coriander leaves and seed. Based on the HAFT residues observed for Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 14 of 21 coriander leaves ( 3.96 ppm) and the observed processing factor of 5.7x for dried leaves, the maximum expected residues in/ on dried leaves would be 22.6 ppm, which will support at tolerance of 25 ppm for dried coriander leaves.

Provided that the use directions on tobacco are clarified with regards to the number of foliar applications allowed and the maximum seasonal use rate, the available field trial data will support the use of bifenthrin on tobacco. As residues in/ on all samples of green tobacco from the tobacco field trails were < 0.1 ppm, no additional data are required to support this use.

860.1520 Processed Food and Feed 45794203. der2 ( potato)

In a field trial conducted during 2001 in WA, bifenthrin ( 1.15% G and 2 lb/ gal EC) was applied to potatoes as a single in furrow application at 0.5 lb ai/ A, followed by two broadcast foliar applications at 0.5 lb ai/ A, for a total of 1.5 lb ai/ A/ season ( 3x rate). The foliar applications were made during tuber development at 42 and 21 days prior to normal maturity. Bulk samples of potatoes were harvested at commercial maturity, at a 21 day PHI, and processed into chips, granules and wet peel using simulated commercial practices. Prior to analysis, potato tubers ( raw agricultural commodity ( RAC)), chips, granules and peels were stored frozen up to 1 month, an interval supported by the available storage stability data.

The GC MSD method ( FMC Report P 3426) used to determine bifenthrin residues in/ on potatoes ( RAC) and processed potato products was adequately validated in conjunction with the sample analyses. The validated LOQ was 0.05 ppm for bifenthrin in/ on potatoes and potato processing products; the LOD was 0.01 ppm.

Following applications totaling 1.5 lb ai/ A ( 3x rate), residues of bifenthrin were nondetectable (< 0.01 ppm) in/ on potatoes ( RAC) harvested at a 21 day PHI, and in processed samples of chips and granules. Residues in wet peel were detectable at 0.02 0.04 ppm, but were still below the LOQ. As residues were < LOD in potatoes, a processing factor for potato chips and granules could not be calculated, and the processing factor for wet peel was estimated to be 3x. The maximum theoretical concentration factor for potatoes is 5x.

Conclusions. The available potato processing study is adequate. Because bifenthrin residues were < LOQ in all samples from the potato field trials ( 46229403. der1) and in potatoes ( RAC) and all processed fractions from the 3x treatment level, HED concludes that residues of bifenthrin in wet peel are unlikely to exceed the LOQ when bifenthrin is applied at a 1x rate. Therefore, separate tolerances will be not required for processed potato fractions.

860.1650 Submittal of Analytical Reference Standards The analytical reference standard for bifenthrin has been submitted to the EPA National Pesticide Standards Repository. Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 15 of 21 860.1850/ 1900 Confined and Field Accumulation in Rotational Crops Bifenthrin TRED, S. Levy, 21 AUG 2002; DP# 283808 Adequate confined and field rotational crop studies are available. Based on the confined study, HED has concluded that the residue of concern in rotational crops is the parent compound only. Based on a maximum seasonal use rate of 0.5 lb ai/ A for annual crops, the confined study and the available field rotational crop study on wheat also support the current rotational crop restrictions on the labels. Crops having bifenthrin tolerances may be replanted at any time, and all other crops may be replanted 30 days following the last application of bifenthrin. No rotational crop tolerances are required.

860.1550 Proposed Tolerances HED has concluded that tolerance expression for plant and livestock commodities should include only parent bifenthrin. Tolerances for bifenthrin residues are currently established on plant commodities at levels ranging from 0.05 ppm ( LOQ) on various commodities to 10.0 ppm on dried hop cones [ 40 CFR § 180.568( a)]. The tolerances proposed by the registrants in the current vegetable petitions are listed below in Table 6, along with HED's recommended tolerance levels. The appropriate tolerance levels were calculated using the methodology formulated by the NAFTA MRL/ Tolerance Harmonization Workgroup for calculating statistically based pesticide tolerances for plant commodities based on field trial residue data ( Attachment 2). Maximum likelihood estimation ( MLE) techniques were used to supplement the dried bean dataset. Based on visual inspection of the probability plot, the lognormality assumption was rejected ( HED Science Advisory Council for Chemistry ( ChemSAC) meeting of 3/ 8/ 06). The value derived by the California Method ( 0.15 ppm) was thus deemed to be appropriate. Revised Sections F with the correct tolerance levels and commodity definitions should be submitted where appropriate.

The available potato data will support a tolerance of 0.05 ppm on tuberous and corm vegetables ( subgroup 1C), and the mustard green data will support a tolerance of 3.5 ppm on leafy Brassica vegetables ( subgroup 5B). The data on dried beans and peas will support a tolerance of 0.15 ppm on shelled dried beans and peas, excluding soybean ( subgroup 6C). The data on cilantro ( coriander) will support separate tolerances of 5 ppm in/ on coriander leaves and seed. Based on the HAFT residues observed for coriander leaves ( 3.96 ppm) and the observed processing factor of 5.7x for dried leaves, the maximum expected residues in/ on dried leaves would be 22.6 ppm, which will support at tolerance of 25 ppm for dried coriander leaves. Summary of Analytical Chemistr y and Residue Data Bi fenthrin DP# s : 310089, 310874, 313738, 313817, 313299, and 317208 Page 16 of 21 Table 6.

It will also be a member of Crop Subgroup 5B: Leafy Brassica greens ( Commodity Reviewers Guide, B. Schneider, 14 JUN 2002). Until that time, " turnip, greens" should have a separate tolerance.

International Tolerances The Codex Alimentarius Commission has established maximum residue limits ( MRLs) for residues of bifenthrin in/ on various commodities. Codex MRLs are expressed in terms of bifenthrin per se, as are U. S. tolerances. The only established Codex MRL relevant to the current petitions is for potato at 0.05 mg/ kg ( See attached International Residue Limits Status sheet). As the recommended tolerance of tuberous and corm vegetables is also 0.05 ppm, this tolerance is in harmony with the Codex MRL for potato. There are no equivalent Canadian or Mexican MRLs for the tolerances being requested in the current petition.

Summary of Teleconference with the Gas Turbine Association Regarding the Proposed New Source Performance Standards for Stationary Combustion Turbines March 23, 2005 Attendees Jaime Pagán, EPA ESD Combustion Group Sims Roy, EPA ESD Combustion Group Bruce Rising, Siemens Westinghouse Barbara Bankoff, Siemens Westinghouse Jordan Haywood, Siemens Westinghouse Leslie Witherspoon, Solar Jennifer Snyder, AGTI Summary of Teleconference The purpose of the teleconference was to discuss the standards of performance for new stationary combustion turbines that were proposed by the EPA on February 18, 2005 ( 70 FR 8314). In particular, the discussion focused on the subject of the Gas Turbine Association ( GTA) providing actual test data.

The GTA understands that EPA is looking for small, oil fired turbine test data, as the amount of data gathered to date as shown in the supporting documents is not ideal. Bruce stated that raw, average, nominal field data will not give statistical variations of what is actually achievable for all turbines. Bruce suggested a 2.5 to 3 sigma variability for setting the standard.

The subject of manufacturer guarantees came up. The GTA pointed out that while emission levels may differ between manufacturers, it may happen that they have the same emission level guarantee. Each manufacturer has a different risk margin that it is willing to bear. These risk margins are based on manufacturer test data, and OEM's are not willing to let their variability be known to the general public. Therefore, they are hesitant to provide EPA with data. The EPA assured GTA that this data would be treated as confidential business information ( CBI).

The EPA emphasized that stack test data is what they seek, without add on controls. Bruce replied that most turbines from 75 to 100 MW have SCR. The EPA asked why these turbines would be an issue for them, as they would easily meet EPA's proposed NSPS emission limits. Bruce replied that there are some simple cycle turbines without add on controls. The EPA requested this stack test data.

Leslie stated that most Solar turbines do not have SCR, as it is not cost effective. She said that people will be forced to use reciprocating engines instead of turbines, and pointed out that those engines emit three to four times as much as turbines.

In regards to oil fired turbine test data, Leslie said that she has asked many of her customers for test data on these, but states do not require testing on secondary fuels, so there are none. Therefore, the best data she can provide on oil fired turbines are test cell data. She said these aren't " real" test reports. They meet the intent of Method 20, but are not tested at 4 operating loads. In her opinion, test cell data would need to be treated as highly confidential. Leslie mentioned the New Jersey State of the Art Manual. She convinced the state of New Jersey to up their limit on small turbines to 65 ppm. On occasion, Solar has warrantied 65 ppm on their oil fired turbines, with specific restrictions on their operating conditions.

Regarding simple cycle turbine emissions, Leslie pointed out that at part loads, the NOx concentration is lower than at full loads ( on a ppm or lb/ hr basis), yet on an output basis, the NOx emissions seem to increase, due to lower efficiencies at lower loads. She claims that a lower environmental impact is seen with the lower volume of emissions, yet partial load is required in order to meet 65 ppm.

Leslie said that turbine owners are afraid to retrofit their turbines with SoLoNOx because they don't want to trigger New Source Review. Sims stated that under the part 60 provisions, which cover NSPS, if emissions are reduced it is not considered a modification, and would thus not trigger NSPS.

According to Leslie, the used equipment market is a big issue with regards to being able to meet the emission limits of the proposed NSPS. Sims stated that even if it is an old turbine at a new site ( without meeting the definitions of reconstruction or modification), it is still subject to subpart GG, not subpart KKKK. Change in ownership does not change applicability. Sims stated that he was writing a memo to OECA stating that this was how he interpreted the rule.

Leslie stated that there are instances when industry may want to uprate a turbine. One example she gave was when there are three to four turbines on an offshore platform that are no longer running near full load at all. One solution to this problem is to " uprate" two of the units and remove the others, so that the two units can cover the power requirements of the previous number of turbines, running at higher loads and thus more efficiently. She stated that though improvements would be made to the turbine, which may fall under the definitions of modification or reconstruction, no lower emissions would result. Therefore, it is a concern that these turbines might be subject to NSPS.

The GTA stated that if the NSPS emission limits were increased to 42 ppm instead of 25, an estimated 90% of issues would diminish; however, Solar Saturn turbines would still not be able to meet this limit.

Sims asked if refurbished units would be tested by the turbine manufacturers; Leslie replied that she believed so, but would check into this.

Jaime encouraged the members of GTA to provide their written comments on the rule, including detailed information in the form of source test reports and permits on why the limits are not achievable.
