EXHIBIT I Soils Information According to the Soil Survey of Weld County, Colorado, Southern Part, (United States Department of Agriculture, Natural Resource Conservation Service, Web Soil Survey 2.0, National Cooperative Soil Survey), there are eight major soil types within the project area: 1. Aquolls and Aquents, gravelly substratum 2. Ustic Torriorthents, moderately steep 3. Bankard Sandy Loam, 0 to 3 percent slopes The location of these soil types relative to the project area is illustrated on the attached Natural Resources Conservation Service map and legend. Detailed descriptions of each NRCS soil type are below. Map Unit. 1- Altvan loam, 0 to 1 percent slopes Component: Altvan (90%) The Altvan component makes up 90 percent of the map unit. Slopes are 0 to 1 percent. This component is on terraces. The parent material consists of old alluvium. Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is well drained. Water movement in the most restrictive layer is moderately high. Available water to a depth of 60 inches is low. Shrink-swell potential is low. This soil is not flooded. It is not ponded. There is no zone of water saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 2 percent. This component is in the R067BY002CO Loamy (formerly Loamy Plains) ecological site. Nonirrigated land capability classification is 4e. Irrigated land capability classification is 3s. This soil does not meet hydric criteria. The calcium carbonate equivalent within 40 inches, typically, does not exceed 3 percent. Map Unit. 3 - Aquolls and Aquents, gravelly substratum Component: Aquolls (55%) The Aquolls component makes up 55 percent of the map unit. Slopes are 0 to 3 percent. This component is on swales, streams, flood plains. The parent material consists of recent alluvium. Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is poorly drained. Water movement in the most restrictive layer is moderately high. Available water to a depth of 60 inches is moderate. Shrink-swell potential is low. This soil is frequently flooded. It is not ponded. A seasonal zone of water saturation is at 27 inches during March, April, May, June, July. Organic matter content in the surface horizon is about 2 percent. This component is in the R067BY035CO Salt Meadow ecological site. Nonirrigated land capability classification is 6w. This soil meets hydric criteria. Component: Aquents, gravelly substratum (30%) The Aquents, gravelly substratum component makes up 30 percent of the map unit. Slopes are 0 to 3 percent. This component is on stream terraces. The parent material consists of recent alluvium. Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is poorly drained. Water movement in the most restrictive layer is moderately high. Available water I - JaT Consultin Inc. Journey Ventures, LLC €+ Journey Ventures Pit V DRMS 112 Permit Application 67
