-(4

-5

-trifluoromethylpy ridine (degradate IV). A drinking water assessment was completed by EFED for fluazifop

-p-butyl in August 2008 1 

### . In that assessment EFED estimated the environmental exposures to fluazifop

-p-acid because the parent rapidly degrades in aerobic environments to its acid form, and therefore, the form most likely to be present in drinking water

. In the current assessment environmental exposures will again be estimated based on the presence of the parent

-acid. In both the 2008 and current assessment the potential human exposure to fluazifop

-acid in drinking water were evaluated using modeling because of the absence of targeted monitoring data for previous uses and no monitoring data for the proposed new uses . Estimated exposure concentrations (EECs) in ground water were modeled using Tier I SCIGROW (version 2.3, dated July 29, 2003) and surface water EECs were modeled using Tier II PRZM (Pesticide Root Zone Model; vers. 3.12 .2, May 12, 2005) and EXAMS (EXposure Analysis Modeling System; Vers. 2.98.04.06)

. The results of the 2008 assessment f or aerial applications indicated that the highest surface water EECs reported for peak, 1 in 10 year average, and the 30 year average as estimated by PRZM/EXAMS for all crop use scenarios were 23.9 ppb, 5.1 ppb, and 3.6 ppb, respectively. For ground applications the highest EECs for peak, 1 in 10 year average, and the 30 year average were 22.8 ppb, 4.9 ppb, and 3.1 ppb, respectively. For ground water the SCIGROW estimated the peak, 1 in 10 year average, and the 30 year average concentrations to be 0.59 ppb

. The results of this current assessment are somewhat higher. For aerial applications the highest surface water EECs reported for peak, 1 in 10 year average, and the 30 year average as estimated by PRZM/EXAMS for all crop use scenarios were 33.4, 6.6 ppb, and 4.4 ppb, respectively. For ground applications the highest EECs for peak, 1 in 10 year average, and the 30 year average were 32.1 ppb, 5.8 ppb, and 3.1 ppb, respectively

. SCI

-GROW estimated the concentration of fluazifop

-acid in shallow ground water sources to be 1.56 ppb

can be attributed to a proposed increase in the maximum number of allowable applications (i.e., 3 vs. 2), and differences in crop use scenarios used in the two assessments

. Environmental Fate and Transport Characterization The fate and transport characteristics of fluazifop

-butyl, its acids and degradates have been extensively

detailed in EFED’s August 2008 report

. In summary, f luazifop

-butyl (PC Code 122805) is the racemic mixture (e.g., consists of equal amounts of the R and S enantiomers) of butyl

-2

- {4

- [5

- (trifluoromethyl)

-2

-py

ridyloxy]phenoxy}propionate. Fluazifop

-p-butyl(PC Code 122809) is the R enantiomer and is more herbicidally active than the S enantiomer (Tu et al. 2001). Both transform primarily via microbial mediated hydrolysis in moist soil and sediments to the fluazifop

-acid which can also exist in the R or S form (MRID 162455; 87493, 92067033, 87492, 92067032, 46190602, 46190605). The chemical structures and names are shown in Appendix A, Table A.1

. Exposure is primarily expected to be to fluazifop

-acid, either in the R or S form (see discussion in Appendix A of EFED’s 2008 assessment)

. Fluazifop

-acid (pKa ~ 3) will primarily be present in the anionic form at environmental pH (Kah et al. 2007). Primary

metabolism pathways are aerobic and anaerobic degradation. Three degradates were measured at greater than ten percent of applied or total radioactivity recovered: fluazifop

-acid, fluazifop

p-acid, and 2

-hydroxy-5

-trifluoromethylpy ridine

. Exposure Modeling Modeling was used to estimate the drinking water exposure for use in the dietary risk assessment of fluazifop

-p-butyl

. Estimated exposure concentrations represent exposure to fluazifop

-acid, with assumptions that fluazifop

-acid may be present in the R or S form or as a mixture of the enantiomers. The f ollowing is a description of the models used, the selection of the model input parameters, and the modeling results. Surface Water Modeling Estimated drinking water concentrations (EDWCs) in surface water were estimated using the Environmental Fate and Effects Division’s (EFED’s) Tier II aquatic models: PRZM (Pesticide Root Zone Model; vers. 3.12 .2, May 12, 2005) and EXAMS (EXposure Analysis Modeling System; Vers. 2.98.04 .06). Calculations were carried out with the linkage program shell

– PE5.0 (November 15, 2006)

- using standard scenarios developed by EFED

. PRZM simulates pesticide fate and transport as a result of leaching, direct spray drift, runoff, and erosion from an agricultural field, and EXAMS estimates environmental fate and transport of pesticides in a surface water body for a 30

-year period. The combined model is designed to estimate pesticide concentrations assuming runoff from the edge of the treated field empties directly into the receiving body (in this case, the index reservoir) . As such, it provides high

-end estimates of the pesticide concentrations. The location of the field is specific to the crop being simulated using site

-specific information on the soils, weather, cropping, and management factors associated with the scenario. The crop/location scenario is intended to represent a high

-end exposure site on which the crop is normally grown. Based on historical rainfall patterns, the receiving water body receives multiple runoff events

during the years simulated. Weather and agricultural practices are simulated for 30 years so that the 10

- year exceedance probability at the site can be estimated. The simulation was generated using 30 years of meteorological data, encompassing the years from 1961 to 1990. Additional information on these models can be found at: http://www.epa.gov/oppefed1/models/water/index.htm

. For drinking water exposure assessments, the Index Reservoir (IR) scenario is used in lieu of the standard pond scenario. It is used in a manner similar to that which the sta ndard pond is used in ecological exposure assessments, except that flow rates have been modified to reflect local weather conditions. The index reservoir (IR) is approximately

82

-m wide and 640

-m long, with an area of 5.3 hectare (ha) . The area of the entire watershed is 172.8 ha. Guidance for using the IR is located at: http://www.epa.gov/pesticides/trac/science/. Proposed application information from the label used in modeling for all proposed uses is shown in Table 1 along with the scenarios used to represent exposure from each use. Foliar applications via ground spray and aerial spray were simulated using the recommended application rate and the maximum application rate combined with the maximum possible number of applications for that rate

. The application date was assumed to be one week after the crop emergence date in the PRZM/EXAMS scenario. Other input parameter values used in this assessment were selected from the environmental fate data submitted by the registrant and in accordance with US EPA

-OPP EFED water model parameter selection guidelines, Guidance for Selecting Input Parameters in Modeling the Environmental Fate and Transport of Pesticides, Version II, February 28, 2002 and Guidance for Use of the Index Reservoir in Drinking W

ater Exposure Assessments, November 16, 1999 . Input values used for modeling are presented in Table 2 and results in Table 3

. Appendix B contains the model output files and tables showing the data used to calculate input values.

### Groundwater Modeling The regression model SCI

-GROW2 (v. 2. 3) was used to estimate the concentration of fluazifop

-acid in ground water. SCI

-GROW estimated the concentration of fluazifop

-acid in shallow ground water sources to be 1.56 ppb . Input parameters for SCI

-GROW are presented in Table

. SCI

-GROW2 is a regression

-based, Tier I screening model that provides a groundwater exposure value to be used in determining the potential risk to human health from drinking water contaminated with the pesticide. SCI

-GROW2 estimates likely groundwater concentrations if the pesticide is used at the maximum allowable rate in areas where groundwater is vulnerable to contamination. Characteristics of such vulnerable areas include high rainfall, rapidly permeable soil, and a shallow aquifer. In most cases, a large majority

of the use area will have groundwater that is less vulnerable to contamination than the areas used to derive the SCI

-GROW2 estimate. The properties of fluazifop

-acid, namely high mobility and long persistence in water (minimal hydrolysis occurred at pH 9 according to Negre et al. 1988 ; MRID 46190601 ) and anaerobic soil (half

life 1 to 3 years, MRIDs 87493, 92067032, and 92067033) indicate that it might persist from year to

year in the subsurface, and move with flowing ground water. Thus, the screening value of 1.56 ppb may not adequately describe the expected behavior of fluazifop

### Monitoring According to EFED’s August 2008 assessment, f luazifop

-butyl has been detected in both river water and ground water samples at concentrations less than 0.2 parts per billion (ppb). This indicates that there is a potential for fluazifop

-butyl to reach surface and ground waters; however, it is not expected to persist as fluazifop

-butyl. This is supported by monitoring results that only detected fluazifop

-butyl in the time frame that it was expected to be used (Martinez et al. 2000). Fluazifop

-acid was not detected in a non-targeted ground water monitoring study completed in Germany (MRID 40439401) ; however, the fluazifop

-butyl results indicate that fluazifop

-acid also has the potential to be found in groundwater samples as it is the primary degradate of fluazifop

-butyl and it is more stable than the parent. The limited monitoring results available are summarized below.

 

### Fluazifop

-butyl was detected in 27% (five out of 18) samples of river water in the Guarena and Almar river basins in Spain and 13% (three of twenty three) samples of ground water (Martinez et al. 2000). All detections of fluazifop

-butyl occurred in the sampling period when fluazifop

-butyl was expected to be used on lentils and chickpeas in the area sampled. When the sampling time was targeted to when fluazifop

-butyl was used, it was detected in 56% of (five out of nine) river water samples at the detection limit to 0.20 μg/Land 20% (three of 15) of ground water samples at the detection limit to 0.18 μg/L

. 3

 

### In a regional groundwater monitoring program conducted in Northern Ireland, fluazifop

-p-butyl was detected in one of 82 ground water samples at a concentration of 0.0041 μg/L (Scott and McConvey

2005).

 

### A groundwater survey was completed in West Germany that analyzed 605 water samples from 95 raw water wells (MRID 40439401). No residues of fluazifop

-acid were found (limit of detection was 0.00008 mg/L).

3 Fluazifop

-butyl usage was expected to occur between April and June and the samples collected between June and September (Martinez et al. 2000). Samples collected between October and December did not detect residues of fluazifop

butyl.

### 9

 

### Fluazifop

-butyl was reportedly detected in three samples from community drinking water supplies in McFarland and Kern County, California at concentrations of 0.06, 0.16, and 0.17 μg/L (http://www.fluoridealert.org/pesticides/fluazifop

-p-butyl.page.htm). No other information was found regarding these reported concentrations and no information is available on the reliability of the data.

 

### Fluazifop

-butyl was listed in the USEPA STORET database and was reported as not detected in 553 ground water samples collected between 1991 and 2002 by the Arizona Department of Environmental Quality (USEPA STORETv2.0 Database; available at http://www.epa.gov/storet/dw_home.html)

. The United States Geological Survey (USGS) National Water

-Quality Assessment (NAWQA) Program Data Warehoouse (available at http://infotrek.er.usgs.gov/traverse/f?p=NAWQA:HOME:1405517206944567) and the California Department of Pesticide Regulation (DPR) Surface Water Database (available at http://www.cdpr.ca.gov/docs/emon/surfwtr/surfdata.htm) were searched for any monitoring information on fluazifop
