EXECUTIVE SUMMARY

A reassessment of drinking water exposure was conducted to support new uses of bifenazate 

(Acramite®-50WS, EPA Reg No. 400-503) for control of mites on: Herb Subgroup 19A (except 

chive and chervil), Fruiting vegetables Group 8-10, Pome Fruit Group 11-10 and timothy grass 

forage in Nevada's Eureka and Humboldt Counties ((PC Code: 002586; DP Barcode:388230). 

The reassessment was initiated based on a request from the Health Effects Division to refine the 

Tier I drinking water concentrations (EDWC) for bifenazate and D1989 from previous drinking 

water assessments (edible podded legumes, succulent-shelled peas, beans,·soybeans). This 

reassessment provides a refinement in the drinking water exposure assessment by implementing 

Tier II PRZMIEXAMS modeling for the bifenazate use on beans; the use scenario driving the 

drinking water exposure values.

The proposed new use requests ground spray applications of 0.375 to 0.5 lb ai/A. Bifenazate 

application is proposed as ground spray for all crop groups. Additionally, aerial applications are 

proposed for the Fruiting Vegetables Group 8-10. The proposed use on timothy grass requests 

ground spray, aerial spray, and chemigation application of 0.495 to 0.747 lb ai/A.

The drinking water assessment was conducted using a total toxic residue approach. Total toxic 

residues include bifenazate and its degradation product of concern, D1989. Based on Tier II

surface water modeling, the concentration of bifenazate and D1989 for the proposed new uses 

should not exceed 9.6 g/L for a 1 inlO year daily peak, 1.7 giL for 1 in 10 year annual average,

and 1.2 g/L for 30 year annual average. Tier I ground modeling indicates the bifenazate and

D1989 concentration should not exceed 0.014 giL for peak and long-term average

concentrations. No monitoring data are available to assess bifenazate or D1989 concentrations in

surface waters. The predicted concentrations of bifenazate and D1989 for the proposed uses are

lower than estimated Tier I drinking water concentrations (EDWC) for beans, edible podded

legumes, succulent-shelled peas, beans, and soybeans uses. Therefore, EFED's previous

recommendation was that HED use the surface water source drinking water exposure estimates

previously calculated for these uses, i.e., bifenazate and Dl989 should not exceed 37.3 g/L for

the daily peak and 11.2 g/L for the annual average.

At the request of HED, EFED has now developed refined Tier II EDWCs for the use on beans, 

edible podded legumes, succulent-shelled peas, beans, and soybeans. EFED refined the EDWCs 

using Tier II PRZM/EXAMS modeling for standard scenarios for beans and soybeans (Table 1). 

The KS com scenario was used to represent a soybean scenario because com and soybeans are a 

common crop rotation. This analysis indicates that the recommended bifenazate and D1989 

concentrations should not exceed 28.58 J.lg/L for the 1 in 10 year daily peak and 6.69 J.lg/L 

for the 30 year annual average (Table 1).

Analysis

Tier II surface water EDWCs were calculated using PRZM (E_esticide Root Zone Model, version

3.12.3, June 2006) and EXAMS (EXposure Analysis Modeling ystem, version 2.98.04.06, 

April 2005) models in the PE5 shell. All Tier II surface water modeling was corrected for 

percent cropped area (PCA).

Surface Water

The chemical input parameters for bifenazate and degradation product D1989 are shown in Table

2. Pesticide application (i.e., method, rate, application interval) was conducted using two 

applications of 0.75 lb a.i./A at a 14 day interval by aerial or ground spray. The EDWCs were 

corrected using a PCA of 0.91.
