## Summary

This assessment provides estimated drinking water concentrations (EDWC) of fomesafen in surface water and in ground water in support of human health risk assessment for assessing of new uses on potato and tomato (

### DP365204)

. In reviewing the new label, EFED finds that label restrictions have been changed on the existing uses. Also several 24C State labels have not been addressed, so these labels are also reviewed for the drinking water assessment

. This drinking water exposure memo addresses the human exposure offomesafen through ingestion of drinking water from the existing uses as well as the new proposed uses. Based on the modeling analysis performed, the 1

- in

-10 year fomesafen concentration in surface

-source drinking water are not expected to exceed 15.89 μg/L for peak (acute) and 3.25 μg/Lfor annual average (non

-cancer chronic). The 30

-year annual average concentration is not expected to exceed 1.56 μg/L (cancer

chronic)

. Therefore, the current EDWCs will not supersede the recommended drinking2



### water values previously performed for this chemical (DP 322213) 

### and the previous drinking water values should be used. 

## Previous drinking Water Assessment

Food uses of fomesafen considered in the previous assessment are cotton and soy beans. Environmental fate data indicate fomesafen should be very mobile and highly

persistent in terrestrial and aquatic environments. Major routes of dissipation from the application site are expected to be runoff and leaching. These data suggest fomesafen occurrence in surface water and groundwater should be anticipated. The 1

- in

-10 year fomesafen concentration in surface

-source drinking water are not expected to exceed 34.8 μg/L for peak and 13.1 μg/L for annual average. The 30

-year annual average concentration is not expected to exceed 6.5 μg/L. Although SCI

-GROW modeling predicts a fomesafen concentration in ground water of 11.2 μg/L, a prospective ground water monitoring study for soybeans on a vulnerable NC site had fomesafen maximum concentrations in ground water of 1 μg/L. EFED recommends using the ground water monitoring concentration of 1 μg/L as the benchmark concentration for fomesafen in ground water source drinking water because it represents actual use conditions of fomesafen on soy beans on a vulnerable soil.



## Label Use Information

Based on the proposed Reflex ® Herbicide (EPA Reg. No. 100

-993), the new uses of potato and tomato are being restricted to apply according to the geographical regions for the application rate and interval. They are shown as Tables 1 and 2.

Among the five regions, region 1 allows the highest application amount as it has a higher rate and a shorter application interval

– 1 year

. For the existing uses, region 1 also allows the highest amount. The maximum single yearly application rate of 0.375 lbs ai/ac is applicable for cotton, soybeans, dry beans and snap beans. Several 24C Reflex State Labels allow pine seedling nursery uses for AL, AR, NC, GA, MS, SC, and TX. The maximum single yearly rate is 0.5 lbs ai/ac for preemergency

application.



## Environmental Fate Summary
Major routes of fomesafen dissipation are leaching, runoff, and microbial degradation. Because fomesafen is persistent and mobile in soil, it is expected to move from the application site into groundwater and surface water. Additionally, off

-site movement of fomesafen is expected through spray drift from aerial and ground spray. The high persistence of fomesafen is expected to contribute to year
-to

-year accumulation in terrestrial and aquatic environments.
Fomesafen is stable to abiotic hydrolysis. It undergoes slow photodegradation in water (t1/2

### = 49 to 289 days). Fomesafen is persistent (t1/2

### =9 to 99 weeks) in aerobic soil and aquatic environments. However, it degrades rapidly (t1/2

### < 20 days) in anaerobic environments. The major degradation product of fomesafen is 5

-(2

- trifluoro

-tolyloxy)

-N

-methylsulphonyl

-panthranilamide (fomesafen amine). A minor degradation product is 5

-(2

### (fomesafen amino acid). Neither degradate has been identified as a toxicological

concern. Fomesafen is expected to be very mobile in soil. Simple partitioning coefficients range from 0.51 in loamy

coarse sand to 2.45 in sandy clay loam soil. Regression analysis indicates fomesafen sorption is not dependent on soil organic matter content. Aged soil column leaching studies indicate degradation products of fomesafen are not mobile in soils; less than 0.06% of applied radioactivity was detected in the leachate samples.
Field dissipation studies in NC, IL, MS, AR, AL, TX, LA, SD, MN, KY, IA and MO indicate fomesafen is moderately persistent to persistent (t1/2

### = 50 to 150 days ) in surface soils under actual use conditions. Fomesafen was detected at depths up to 30 inches in the soil profile. Fomesafen amine was the only degradation product identified in field dissipation studies. Prospective ground water monitoring in NC indicates fomesafen

moved through the soil profile into medium and deep ground water.
Fomesafen has a low potential for bioaccumulation in fish tissues. Bioaccumulation factors for fomesafen were 0.7 for whole fish, 0.2 for edible tissues, and 5.2 for nonedible tissue. Bioaccumulated residues were depurated during a 14

-day depuration period.



## Surface Water Assessment
The new proposed uses of fomesafen were modeled in various scenarios in PRZM/EXAMS using index reservoir (IR) scenarios with percent crop area (PCA) adjustment factors. The estimated drinking water concentrations in surface water were derived from Tier II PRZM (Pesticide Root Zone Model; Version 3.12.2, May 12, 2005) and EXAMS (Exposure Analysis Modeling System; Version 2.98.04.06, Apr. 25, 2005). PRZM simulated pesticide transport as a result of runoff, erosion, and off

-target spray drift from an agricultural field. EXAMS estimates environmental fate and transport of pesticides in surface water. Additionally, a graphical interface shell, PE5.pl (dated 7/27/2007), was employed to facilitate the input of use

-specific information in the PRZM input and the EXAMS chemical files (Table 3).
Linked crop

-specific scenarios and meteorological data were used to estimate exposure as a result offomesafen uses on various crops. Simulations were done using the index reservoir in EXAMS, which is a surrogate for a permanent surface water drinking water environment. Weather and agricultural practices were simulated over 30 years to estimate the 1

-in

-10 year exceedance probability atthe site.5

and, therefore, pesticide transport. The application information used in the PRZM/EXAMS modeling is provided in Table 4

Since the scenarios with one application for every two years would expect to generate less EDWC than the scenarios with one application per year, therefore, those scenarios applied every two year were not modeled for this drinking water assessment

. 

### The modeling results of various scenarios for estimated drinking water concentrations (EDWC) are listed in Tables 5 (before PCA adjustment) and 6 (after PCA adjustment). The PCA values are 0.2, 0.41, and 0.87 for cotton, soy beans, and others, respectively. The complete PE5 outputs are included in the Appendix

. According to Table 6, Florida Tomato scenario with aerial application has the highest 1 in 10 year annual peak concentration of 15.89 μg/L, and this is the recommended value to

assess acute concerns. Tennessee Nursery scenario with aerial application has the highest 1 in 10 year annual mean concentration of3.25 μg/L, which should be used for non

cancer chronic assessment. The same Tennessee Nursery Scenario also has the highest 30 year annual mean concentration of 1.56 μg/L, which is recommend for assessing cancer chronic
