The chronic dietary risk estimates (food + water) 9.2 % of the chronic population - adjusted dose (cPAD) for the general U.S. population and 30 % of the cPAD for the most highly exposed population subgroup ( all infants (<1 ye ar old) and are thus below HED’s level of concern (<100% cPAD). Cancer Dietary (Food and Drinking Water) Exposure Results and Characterization Saflufenacil is classified as “not likely carcinogenic to humans.” Therefore, cancer risk is not a concern for this chemical. I. Introduction Dietary risk assessment incorporates both exposure and toxicity of a given pesticide. For acute and chronic assessments, the risk is expressed as a percentage of a maximum acceptable dose (i.e., the dose which HED has concluded will result in no unreasonable adverse health effec ts). This dose is referred to as the population - adjusted dose (PAD). The PAD is equivalent to point of departure (POD, NOAEL , LOAEL, i.e. ) divided by the required uncertainty

or safet y factors. For acute and non - cancer chronic exposures, HED is concerne d when estimated dietary risk exceeds 100% of the PAD. HED is generall y concerned when estimated cancer risk exceeds one in one million.

; or see SOP 99.6 (20 - AUG - 1999). The most recent dietary

exposure risk assessment for saflufenacil was conducted by G. Kramer (Memo, 22 - JUL - 2009, D364183). II. Residue Information Saflufenacil Proposed and Registered Uses: Saflufenacil is currentl y registered for use on legume vegetables ( Crop Group 06), the foliage of legume vegetables ( Crop Group 07), cereal grains ( Crop Group 15), forage, fodder , and straw of cereal grains ( Crop Group 16), cotton , and sunflower . BASF has submitted a proposal to amend the established tolerances for saflufenacil on cotton, dry bean, dry pea, and soy

bean (PP# 0F7744 ) . The amended tolerances on these crops are the result of the proposed harvest aid/desiccation use pattern for SharpenTM 

### Powered by Kixor Herbicide (EPA R eg. No. 7969 - 278); the currently - registered uses are for preplant application . In addition, BASF has submitted a proposal for a new use of SharpenTM 

### on Oilseeds, Rapeseed Subgroup 20A as harvest aid/desiccant (PP#0F7744). Residues of Concern: The nature of the residue in plants, rotational crops, and livestock is adequatel y understood based on acceptable metabolism studies conducted on corn (preplant application), so ybean (preplant and pre harvest application), tomato (preplant application), rotational cro ps, lactating goats, and laying hens. The HED Residues of Concern Knowledgebase Subcommittee (ROCKS) determined that residues of concern for the tolerance expression and risk assessment in plants consist of saflufenacil, M800H11, and M800H35 ; and that saf lufenacil is the only

residue of concern in livestock (Memo, B. Daiss, 1/6/09; D 359645 ). An additional major metabolite ( M800H02 ) that is not included in the tolerance expression was observed in so ybean seed following pre harvest application . As the struc ture of M800H02 is closely related to the parent compound and it is the precursor of the regulated metabolite M800H11, RAB1 concludes that M800H02 is a residue of concern for risk - assessment purposes in crops following post - emergence treatment.

Recommended Tolerances: Based on the residue chemistry data submitted with the current petition s , HED recommended for establishment of the following tolerances (G. Kramer , 3/24 / 11 ; DP# 381129 ): Table 2. Tolerance Summary for Saflufenacil. Commodity Recommended Tolerance (ppm) Cotton, gin byproducts 0.45 Cottonseed Subgroup 20C 0.20 Sunflow er Subgroup 20B 1.0 Pea, vines 17 Grain, aspirated fractions 10 Soy bean, hulls 0.50 Soy bean, seed 0.10 Pea and bean, dried shelled, except soybean, subgroup 6C 0.30 Rapeseed Subgroup 20A 0.45 Cattle, liver 2.5 Cattle, meat byproducts, except liver 0.05 Goat, liver 2.5 Goat, meat byproducts, except liver 0.05 Sheep, liver 2.5 Sheep, meat byproducts, except liver 0.05 Horse, liver 2.5 Horse, meat byproducts, except liver 0.05 

### Residue Data used for Acute and Chronic Assessments: The acute and chronic assessments were based on the assumption of tolerance - level residues for all commodities, except for cottonseed; sunflower subgroup 20 B ; soy bean, seed; vegetable, legume, subgroup 6C, pea and bean (except soy bean); and rapeseed subgro up 20A . For the se crops , residues were also based on the recommended tolerances; however, a correction factorSaflufenacil Dietary Exposure and Risk Assessment DP Number: 381976

### Page 5 of 18 was applied to the tolerance level to account for the M800H02 metabolite included in the risk assessment as a result of preharvest uses . The add itional metabolite, M800H02 , w as observed in the metabolism studies of preharvest - treated soy bean seed, comprising 2 6 . 3 % of the total radioactive residues ( G. Kramer, 3/24 / 11 ; DP# 381129 ). Since the toxicity of the M800H02 is expected to be comparable to the parent compound, it was included in the risk assessment for preharvest uses , but not in the tolerance expression. To account for this additional toxicity exposure, the recommended tolerance level was multiplied by a co rrection factor of 1. 7 x, where 1. 7 = (Metabolites in Risk Assessment)/(Metabolites in Tolerance Expression). 1.7 = (Saflufenacil + M800H11 + M800H02 + M800H35)/(Saflufenacil + M800H11 + M800H35) = (2 6 . 1 % + 10. 9 % + 2 6 . 3 % + 0% )/( 2 6 . 1 % + 10. 9 % + 0% ) 

### Ther efore, in the acute and chronic assessments , a residue of 0.34 ppm was used for cottonseed; a residue of 1.7 ppm was used for sunflower subgroup 20 B ; a residue of 0.17 ppm was used for soy bean, seed; a residue of 0.51 ppm was used for vegetable, legume, subgroup 6C, pea and bean (except soy

bean); and a residue of 0.76 ppm was used for rapeseed subgroup 20A (see Table 3 ). Table 3 . Corrected Residues Used in the Chronic Assessment.

The recommended tolerance level was multiplied by a correction factor of 1. 7 x, where 1. 7 = (Metabolite s in Risk Assessment)/(Metabolite s in Tolerance Expression). 2 These are HED - recommended tolerances based on Petition s 0F7744 and 0F7766 . 

### %CT Information : The chronic assessment was based on the assumption of 100% CT for all commodities. Processing Factors: DEEM TM 

### 7.81 default processing factors were used for all processed commodities (where provided). III. Drinking Water Data The Estimated Drinking Water Concentrations (EDWC s ) used in the dietary exposure risk assessment were provided by the Environmental Fate and Effects Division (EFED) in a memorandum dated 0 4 / 1 5 /0 9 (Memo, G . Orrick ; DP# 349860 ) . Water residues were incorporated directl y into the DEEM - FCID TM 

### into the food cat egories “water, direct, all sources” and “water, indirect, all sources.” Screening EDWC s ( Table 3 ) of saflufenacil were generated with FQPA Index Reservoir Screening Tool (FIRST) for surface water and with PRZM GW for ground water. Modeled application rates represent the maximum use patterns of five proposed end - use labels with selected uses on row crops, orchard trees, vineyards, tree plantations, and non - agricultural areas . Remaining model input parameters were chosen according to current guidance (USEPA, 2002).Saflufenacil Dietary Exposure and Risk Assessment DP Number: 381976

### IV. DEEM - FCID TM 

### Program and Consumption Information Saflufenacil acute and chronic dietary exposure assessments were conducted using DEEM FCID TM 

### , Version 2.03, which incorporates consumption data from USDA’s CSFII, 1994 - 1996 and 1998. The 1994 - 96, 98 data are based on the reported consumption of more than 2 0,000 individuals over two non - consecutive survey day s. Foods “as consumed” ( i.e. , apple pie) are linked to EPA - defined food commodities ( i.e. apples, peeled fruit - cooked; fresh or N/S; baked; or wheat flour - cooked; fresh or N/S, baked) using publicl y available recipe translation files developed jointly

by USDA/ARS and EPA. For chronic exposure assessment, consumption data are averaged for the entire U.S. population and within population subgroups, but for acute exposure assessment are retained as ind ividual consumption events. Based on anal ys is of the 1994 - 96, 98 CSFII consumption data, which took into account dietary patterns and survey respondents, HED concluded that it is most appropriate to report risk for the following population subgroups: the general U.S. population, all infants (<1 ye ar old), children 1 - 2 ye ars old, children 3 - 5 ye ars old, children 6 - 12 ye ars old, youth 13 - 19 ye ars old, females 13 - 49 ye ars old, adults 20 - 49 ye ars old, and adults 50+ y ears old. For chronic dietary

exposure assessment, an estimate of the residue level in each food or food form ( i.e. , orange or orange juice) on the food commodity residue list is multiplied by the average dail y consumption estimate for that food/food form to produce a residue intake estimate. The resulting residue intake estimate for each food/food form is summed with the residue intake estimates for all other food/food forms on the commodity residue list to arrive at the total average estimated exposure. Exposure is expressed in mg/kg body we ight/day and as a percent of the cPAD. This procedure is performed for each population subgroup. For acute exposure assessments, individual one - day food consumption data are used on an individual - by - individual basis. The reported consumption amounts of each food item can be multiplied by

a residue point estimate and summed to obtain a total daily pesticide exposure for a deterministic exposure assessment, or “matched” in multiple random pairings with residue values and then summed in a probabilistic asse ssment. The resulting distribution of exposures is expressed as a percentage of the aPAD on both a user (i.e., onl y those who reported eating relevant commodities/food forms) and a per - capita (i.e., those who reported eating the relevant commodities as we ll as those who did not) basis. In accordance with HED policy , per capita exposure and risk are reported for all tiers of anal ysis. However, for Tiers 1 and 2, an y significant differences in user vs. per capita exposure and risk are specifically identifi ed and noted in the risk assessment.Saflufenacil Dietary Exposure and Risk Assessment DP Number: 381976

The results reported in Table 3 are for the general U.S. population, all infants (< 1 y ear old), children 1 - 2 ye ars old, children 3 - 5 ye ars old, children 6 - 12 ye ars old, youth 13 - 19 ye ars old, females 13 - 49 ye ars old, adults 20 - 49 years old, and adults 50+ ye ars old. Results of Acute and Chronic Dietary Exposure Analy ses The acute die tary risk for food and drinking water utilized (<1 % of the aPAD for the U.S. population. The acute dietary risk for the highest exposed population subgroup, a ll i nfants (<1 ye ar old) , i s <1 % of the aPAD .

### VII. Characterization of Inputs/Outputs These acute and chronic dietary exposure and risk estimates are conservative since they assumed 100% CT, DEEM TM 

### 7.81 default concentration factors , and tolerance - level or higher residues and were based on screening level estimates of drinking water concentrations generated b y PRZM GW . They

could be further refined through the use of anticipated residues, empirical processing factors and % CT data, as well as refined drinking water estimates. VIII. Conclusions The acute and chronic dietary exposure and risk analy s e s using DEEM - FCID TM 

### indicates that dietary risk s to saflufenacil from food and drinking water are well below HED’s levels of concern for this pesticide. Estimated acute dietary risk s are <1 % of the aPAD for the general U.S. population and all population subgroups and estimated chronic dietary risks are ≤ 30 % of the cPAD for the general U.S. population and all population subgroups .
