It is important to note that modeling for EDWCs from surface and ground water is performed using the single application rate of 1.5609 lb a.i/A applied 2 times to soil planted with ornamentals. This represents the highest seasonal application rate among the identified four types of applications. However, using this application rate/frequency allows establishing first level values suitable for screening purposes. They may be referred to as likely upper bound values due to the use of the chemical at the maximum application rate and additional refinements can be developed should they be needed.

Uncertainties
EDWCs for cyazofamid and degradates were estimated for drinking water based on half-lives calculated from supplemental aerobic soil and aerobic/anaerobic water/sediment laboratory fate studies. In these studies, suspected lack of extraction may have underestimated the half-lives of cyazofamid and degradates possibly resulting in lower model estimates for the EDWCs. In this respect, it is noted that major identified degradates (CCIM, CCIM-AM and CTCA) may not constitute a significant part of the late accumulated un-characterized bound residue (due to the apparent adequate extraction of these degradates); however, a degree of uncertainty exists in such estimates until new studies with proven extraction procedures are submitted. No data were submitted by the registrant suggested that attempts were made to extract or analyze significant soil or sediment bound radioactivity. Complete characterization of the fate of cyazofamid requires data to prove that no parent or degradate was left as part of the bound residue and to characterize various other components that may be present.  As a result, EFED is requiring additional fate information/data be submitted to assess the impact of these residues on the environment.

In this Memo, the acute values were obtained from summation of EECs of three runs: Parent alone, CCIM degradate, and CCIM-AM degradate. This means that resultant EDWCs are expected to be conservative because of nearly double counting of the application rate (full rate for parent + equivalent rates for CCIM and CCIM-AM). On the other hand, chronic values were obtained from EECs for the terminal degradate which was considered to be stable in all of its fate parameters.  Therefore, the resultant EDWCs are expected to be highly conservative.

Degradates CCTS, HTID, CDTS and p-Toluamide were found as major degradates only in aqueous direct photolysis.  Significant amounts of CCIM and CCTS form early (within a day), peak and show clear decline while HTID, CDTS and p-Toluamide form/peak late (within days) and show only slight or no decline under the conditions of the direct photolysis experiment. Persistent degradates HTID, CDTS and p-Toluamide are therefore not expected to be important components in natural aquatic systems because of their late formation.  MARC also believes that none of these degradates will be more toxic than the parent.  In addition, based on the use pattern, and the nature of parent, aqueous direct photolysis may not be a major route of degradation in most natural environments.   The Metabolism Assessment Review Committee (MARC) recommended to exclude these degradates from drinking water assessment. However, EFED will ask the registrant for hydrolysis/aerobic soil studies on the degradate CCTS to confirm that degradates HTID, CDTS and p-Toluamide were only photolytic degradates resulting from long exposure to light energy.
APPENDIX I:  Background information on PRZM/EXAMS

a. PRZM and EXAMS models and the Index Reservoir Scenario
The linked PRZM and EXAMS models are used in this case as a second tier screen designed to estimate the pesticide concentrations found in water for use in drinking water assessments. They provide high-end values on the concentrations that might be found in a small drinking water reservoir due to the use of pesticide. The Drinking Water Index Reservoir scenario includes a 427 acres field immediately adjacent to a 13 acres reservoir,  9 feet deep, with continuous site-specific flow. This amount can be reduced due to degradation in field and the effect of binding to soil.  Spray drift is equal to 6.4% of the applied concentration from the ground spray application and 16% for aerial applications.

The PRZM/EXAMS modeling system with the Index Reservoir scenario also makes adjustments for the percent cropped area. While it is assumed that the entire watershed would not be treated, the use of a PCA is still a screen because it represents the highest percentage of crop cover of any large watershed in the US, and it assumes that the entire crop is being treated.  Various other conservative assumptions of this scenario include the use of a small drinking water reservoir surrounded by a runoff-prone watershed, the use of the maximum use rate and no buffer zone.

b. SCI-GROW
SCI-GROW is a screening model which the Office of Pesticide Programs (OPP) in EPA frequently uses to estimate pesticide concentrations in vulnerable ground water. The model provides an exposure value which is used to determine the potential risk to the environment and to human health from drinking water contaminated with the pesticide. The SCI-GROW estimate is based on environmental fate properties of the pesticide (aerobic soil degradation half-life and linear adsorption coefficient normalized for soil organic carbon content), the maximum application rate, and existing data from small-scale prospective ground-water monitoring studies at sites with sandy soils and shallow ground water.

Pesticide concentrations estimated by SCI-GROW represent conservative or high-end exposure values because the model is based on ground-water monitoring studies which were conducted by applying pesticides at maximum allowed rates and frequency to vulnerable sites (i.e., shallow aquifers, sandy, permeable soils, and substantial rainfall and/or irrigation to maximize leaching). In most cases, a large majority of the use areas will have ground water that is less vulnerable to contamination than the areas used to derive the SCI-GROW estimate. SCI-GROW provides a groundwater screening exposure value to be used in determining the potential risk to human health from drinking water contaminated with the pesticide. SCI-GROW estimates likely groundwater concentrations if the pesticide is used at the maximum allowable rate in areas where groundwater is exceptionally vulnerable to contamination.  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-GROW estimate.
