Th is memorandum transmits an update of the Screening Leve l Usage Analysis (SLUA) report for Fomesafen that was done i n 20 1 2. The usage data in the updated 2015 SLUA are an amal gamation ofUS D AINASS and Private Pesticide Market Research data from 2005 to 20 14. As meas ured by ave r age ann u al l bs

### Sodium salt of Fomesafen (123802) and Fomesafen (123803) Scre e ning Level Usage Analysis (SLUA) Date: December 29,2015 What is a Screening Level Usag e Analysis (SLU A)? • Avai l ab l e estimates of pesticide u s age data fo r a par 1icular act ive in gredient that is used on agricultural crops in the United States. • Pesticide u sage data obta in ed f r o m var i ous so urces. The data are then m erge d , averaged , and r ounded so that the presented information is not p r opr i etary , busi ness confi d en ti al , or tr ade secret. 

### What does it contain? • Pestic i d e usage data fo r a s ingle active in gredient only. • Agricu l t ur a l u s e s ites (c r ops) that the pest i cide is reported to be used o n . • Availab l e pe s ticide usage in formation fro m states that prod uce 80% of crop ac r es pla nt ed in th e United States , in most cases , o r l ess than 80% , i n rare cases , depend in g on the scope of the survey and avai l ab l e resources. • A nnu al percent of c r op treated (ave rage & m ax imum) for each agricultu ral crop . • Av erage a nnu al pounds of the pest i cide app li ed for eac h agr i cu ltural crop (i
. e. , for the sta tes surveyed, no t for the ent ire Uni ted S tates)
. 

### What assumptions can I make about the reported data? • Average pounds of ac tive ingredient applied- Value s a r e calculated by merging pesticide usage data so ur ces together; ave r ag in g ac r oss all observations, then r oundi ng . No te: 

### If the estimated valu e i s less than 500 , th e n that value is lab e l ed < 500. Estima ted valu es b e twe e n 500 & < 1 , 000, 000 are rounded to 1 significant digit. Estimated valu es of1 , 000 , 000 or gr eate r ar e rounded to 2 significant digits .) • Aver age perce nt of crop treated

- Values are calc ul ated by merging data sources together ; averag i ng by year , averag ing across a ll yea rs , & rou ndi ng to the nearest multipl e of 5
. Note: 

### If the estimated value is less than 2.5 , then the valu e is labeled < 2.5. 

### If the estimated valu e is l ess than 1, then the value is lab e led < 1. • M ax imum p e rc e nt of crop treated

- Va lu e is the s in g l e maximum value reported across all da ta so u rces, across a ll yea r s , & rou nded up to the nearest mu ltipl e of 5
. Note: 

### If the estimat ed valu e is less than 2
. 5, then th e value is lab e led < 2.5. 

### What are the data s ources u se d? • Unit e d States Departm e nt of Agriculture's National Agricultural Statistics Service (USDA-NASS)- pest i

cide usage data from 2005 to 20 14. NASS data are based on su r veys that focus o n the top-prod uci ng states that together accou nt for the major i ty of U.S. acres or production of the surveyed commodity
. NASS aims to cove r at a min im um 80 percent of the targeted fr ui t, vegetable, a nd field crop ac r es p l anted in the Unite d States
. Farm l eve l data a r e combined d uring s umm ary and, pending com pli a nce with disclosure rules , published at the state and nationa l le vels. NASS co ll ects agr i cu l t ura l u sage data for various crops on a rotating sc hed ul e . • Private pe st icid e market re search -pesticide usage data from 2005 to 2013. The Private Pesticide Market Research data is a lso a survey that covers pestic i de u sage o n agricultural crops . The survey data acco unts for at l east 80 percent of US ac r es/ product i o n ofthe surveyed commodities. Surveys are conducted a nnuall y. • Ca lifornia Department of Pesticide Regulation ( DPR) P est icide Use Reporting (PUR) data for 2005 to 2012. The P UR database contai ns deta iled records and sum m ar i es of agr i cu l t ura l ap pli catio ns of pestic i des on crops that are obtained from a cens u s and published an n ua ll y. 

### What are the limitations to the data? • Addit i onal regi s tered use s may exist but are not included because the ava ilab l e s urveys do not report usage (e.g. , sma ll acreage c r ops). • Lack of reported usage data fo r the pesticide on a crop does not imply ze r o u sage. • Usage data o n a par1icular s ite may be noted in data sources , but not quantified. In these insta nces , t he s it e wo u ld not be repor1ed in the S LU A
. • No n- agr i c ul tu r al u se sites (e.g. , turf, post-harvest , mosqu i to control , etc
.) are not reported in the S LUA
. A sepa r ate request must be made to receive these est im ates. • Some sites show som e u se , even though they are not on the l abe l. T hi s usage coul d be d ue to vario us factors , i ncludi ng , but not limited to Section 18 requests , ex isting stocks of the c hem i ca l , data collection e rrors, a nd exper imental use permits (EUPs)
