Appendix 3-5. Downstream Dilution Tool ResultsIntroductionThe Downstream Dilution Tool is a GIS-based algorithm designed to determine the downstream extent of exposure in flowing streams and rivers where direct/indirect effects and/or habitat modification may occur. In Step 1 of the ESA process, the aquatic exposure estimates derived from the downstream dilution tool and AgDRIFT are compared to toxicity thresholds to define the action area which includes the initial area of concern (i.e., immediate area where pesticides are applied) and additional areas that may be affected directly or indirectly by the pesticide application due to offsite transport. The downstream extent of the action area includes the area where the predicted levels of the cumulative percent use area exceed the highest “estimated exposure concentration (EEC) to threshold ratio” (i.e., the ratio of the highest EEC to lowest toxicity threshold). In essence this provides an estimate of streams where estimated environmental concentrations have the potential to exceed a toxicity threshold. In Step 2 of the ESA process, the tool is used to assess the impact downstream from specified use sites, specific to the label, using taxa-specific thresholds in order to support the weight of evidence and effects determinations. For Step 3, a process is being developed to generate a text delimited file which will list the stream reaches and estimated exposure concentrations EECs in upstream reaches as well as for the streams in the species ranges and critical habitat.Estimation of Pesticide Use Area and Dilution FactorsThe initial area of concern is derived from aggregated and modified sources of land cover information, as described in Attachments 1-3 and 1-6. In addition to the landcover-based pesticide use footprint, the initial area of concern includes the stream segments found within those land cover areas. Stream segments are obtained from the NHDPlus V2 a 1:100K National hydrography dataset for the contiguous United States. For each stream reach in the hydrography network, the cumulative attribute and allocation tool (CA3T) included in the NHDPlus toolkit () is used to calculate the catchment cumulative percent use area (PUA) for each individual pesticide. The PUA is the total area where the pesticide could potentially be used divided by the total upstream contribution area. Pesticide exposures in the streams within the initial area of concern are conservatively assumed to be represented by the estimated environmental concentrations derived from the Pesticide in Water Calculator (PWC), which are then used in the downstream calculations. The downstream dilution approach calculates the dilution factor (DF), or the maximum threshold/EEC ratio, expressed as a percentage, which needs to be achieved in order for EECs to fall below the threshold. For instance, if the EEC is 10 ?g/L and the threshold is 1 ?g/L, then the DF is 10%. The tool uses PUA factors as a surrogate for flow to assess dilution. While the PUA factor doesn’t account for all of the effects contributing to pesticide dilution in a stream (e.g., downstream mixing and advection, degradation, dilution from incoming runoff water that does not contain pesticide), it provides an indication of the ratio of the amount of area in a watershed that could be treated with a pesticide, and hence contribute pesticide via runoff, to the total area of the watershed contributing to runoff. As such, if only 10% of the watershed can be treated with the pesticide, then, conservatively speaking, only 10% of the runoff to the stream in the watershed would contain pesticide and the remaining 90% of the runoff from the watershed would in effect dilute this pesticide contribution.The dilution approach uses the NHDPlus dataset for the downstream analysis. After the stream segments in the initial area of concern are identified, the dilution model traverses downstream from each stream segment. At each downstream node, the PUA is compared to the DF. If the PUA for that segment exceeds the DF, the stream segment is included in the downstream extent. The tool continues traversing downstream until the PUA no longer exceeds the DF. For example, in Figure B 3-5.1, the DF would not be achieved until the downstream extent in the southeast corner watershed was reached.Figure B 3-5. SEQ Figure \* ARABIC 1. Graphical depiction of downstream dilutionAs mentioned above, the PUA at each downstream node is estimated by taking the total area of the individual class divided by the total upstream contribution area. For instance, in Figure B 3-5.1, the PUAs for the two northwest catchments were estimated as follows:PUA1 = 22 A / 100 A = 0.22PUA2 = 15 A / 100 A = 0.15For the catchment just downstream, which has a total area of 85 A, the PUA is estimated as followsPUA3 = ((0.15 x 100 A) + (0.22 x 100 A))/(100 A + 100 A + 85 A) = 0.13Use of Downstream Dilution Tool in Step 1In Step 1, the highest 1-in-15 year peak EEC is estimated from the PWC for all hydrologic unit code level 2 (HUC 2s) for Bin 2 (see Attachment 3-1 for information on aquatic bins) for the rights-of-way scenario (a protective scenario utilizing a high curve number) and the lowest aquatic endpoint to estimate the DF. For each aquatic species, if the downstream dilution tool predicts concentrations that exceed the aquatic threshold for catchments that overlap the species range or designated critical habitat, a May Affect call is made. For diazinon, the highest 1-in-15 year peak EEC is 239,000 ?g/L (HUC 15) and the endpoint is 0.044 ?g/L (aquatic invertebrates, mortality). For Step 1, land cover data for Orchards and Vineyards, Vegetables and Ground Fruit, Nurseries, and Cattle Eartag use were incorporated into the analyses. Step 1 determinations are provided in Table B 3-5.1. The Percent of Stream Miles Affected reported in the table is the ratio of the stream miles exceeding the threshold divided by the total stream miles in the species range or critical habitat. If the Percent of Stream Miles Affected is greater than 0, then a May Affect determination is made. ESA Taxa assignments can be found in Attachment 1-10. Downstream dilution analysis resulted in a May Effect call for all aquatic species based on their range (398 species) or critical habitat (173 species). It should be noted that the downstream dilution tool was not used to assess impacts to certain aquatic species (i.e., cave dwelling species, offshore marine species, etc.); these species are being addressed qualitatively in separate parts of the Biological Evaluation (Chapter 4, Sections 6.2 through 6.4).Table B 3-5.1.

FrogAquatic AmphibiansMay Affect91%Use of Downstream Dilution Tool in Step 2For each HUC 2, the highest 1-in-15 year EEC for Bin 2 is used for each individual registered use pattern. For HUC 2s with more than one meteorological file, the highest EEC from the two sets of runs is selected. For multiple pesticide uses that are covered by a particular CDL, the highest EEC for the data layer is used. Multiple effects thresholds are considered in the analysis and the lowest threshold, based on the available thresholds for each line of evidence (i.e., mortality, growth, reproduction, behavior, and sensory effects) for each taxonomic group is used. For Step 2 of the downstream dilution analyses, only Orchards and Vineyards, Vegetables and Ground Fruit, and Nursery land covers were considered, as they were the only ones for which EECs were generated. Cattle Eartag use was not included in the aquatic exposure analyses as runoff from this use is not expected.For each species and each HUC 2, the downstream dilution tool estimates the percent of stream miles in the species range and critical habitat where the downstream dilution concentration is above a particular threshold and the corresponding use pattern that has the greatest impact. Step 2 downstream dilution evaluations are provided for the species range and critical habitats in Table B 3-5.2 and B 3-5.3, respectively, and are used to inform the NLAA/LAA determinations for the species. The HUC 2 column depicts the hydrologic unit code level 2 associated with the analysis and species location. The “Multiple HUCs?” column indicates whether the species can be associated with more than one HUC 2. The Species Range, HUC 2 depicts the total number of stream miles, in the respective HUC 2, in the species range or critical habitat. The Species Range, All HUCs depicts the total number of stream miles in the species range or critical habitat. The Threshold Value column reports the threshold value used in the determination of stream miles affected. Individual thresholds are described in a footnote to the tables. The Use Impacting Species column indicates the modeled data layer that generated the highest impact on the species as reflected in the stream miles affected. In cases where a mollusk with an obligate relationship to a fish had been established, both the mollusk and fish endpoints were evaluated. In these cases, the mollusk is listed twice in the tables, once for the mollusk and once for the fish. Table B 3-5.4 provides a listing of species where concentrations from downstream dilution were below all relevant species-specific thresholds. In most cases, the species were not located in streams that were hydrologically connected to an upstream segment where a diazinon use (e.g., orchard, vegetable, or nursery) could occur nor were they in streams that could potentially receive direct or spray drift runoff from a pesticide treated field (i.e., no vegetable, orchard, or nursery uses in watershed). If these species do not utilize terrestrial habitats and are not impact by Cattle Eartag use, these species are considered NLAA and are classified as such in Attachment 1-6.A text delimited file which lists the EECs in upstream reaches, as well as for the streams in the species ranges and critical habitat, is under development for use in Step 3 of the ESA process and will be available with the final BE. It should be noted that the downstream dilution tool was not used to assess impacts to certain aquatic species (i.e., cave dwelling species, offshore marine species, etc.); these species are being addressed qualitatively in separate parts of the Biological Evaluation (Chapter 4, Sections 6.2 through 6.4).Uncertainties in Analysis The geographic data sets used in this analysis are limited with respect to their accuracy and timeliness. The CDL represents the most current and comprehensive collection of national crop-specific land use and land cover information for the United States. The current analysis considers CDL products from 2011-2014. Additional data sets were included to account for uses not clearly defined by the CDL, such as non-agricultural uses. These supplemental data and associated uncertainties are discussed in Attachment 1-3.Hydrographic data are from the NHDPlus data set (). NHDPlus contains the most current and accurate nationwide representation of hydrologic data. At a spatial scale of 1:100,000, the NHDPlus might omit the smallest streams and waterbodies. In addition, in some isolated instances, there are errors in the data including missing or disconnected stream segments and incorrect assignment of flow direction.The relatively coarse spatial scale and general classification categories of these data sets preclude use of the data for highly localized study. Additionally, some labeled uses are not possible to map precisely due to the lack of appropriate spatial data in the data layers. These labeled uses and their associated uncertainties are discussed in Attachment 1-3.Table B 3-5.2.
