' • tnnedy/Jenks Consultants ' Section 5: Soil In the Conceptual Compliance Plan, Musco proposes to supply reclaimed water to offsite properties near the Facility.According to the San Joaquin Soil Survey (NRCS, 1992) (Soil Survey), soils at both potential reclamation sites, the Jepsen Ranch and the Valley View ' Thoroughbred Farm, have been mapped as Capay clay and Stomar clay loam, in differing proportions. The Jepsen Ranch is mapped predominantly as Capay clay (identification number 118, 0-2% slope)with lenses of Stomar clay loam (identification number 252, 0-2% slope) along ' the southern half of the property. The Valley View Thoroughbred Farm is mapped as predominantly Capay clay(identification number 119, 2-5% slope)with the western quarter of the property mapped as Stomar clay loam (identification number 252, 0-2% slope). The ' proposed reclamation areas, as well as mapped soil types, are shown in Figure 5. The Capay clay soil is described as very deep and moderately well-drained occurring on nearly level terrain (Jepsen Ranch) and 2-5 percent slopes (Valley View Thoroughbred Farm). The soils on these properties have been described as neutral to moderately alkaline. The surface layer has been described as grayish brown or dark grayish brown clay to approximately 34 inches bgs. Below 34 inches, Capay soil is described as pale brown to yellowish brown, ' massive, with seams of lime. Soil permeability is reported as slow with reported ranges of 0.06 to 0.2 inches per hour. Runoff is reported as slow and the hazard for water erosion slight. Based on measured soil textures, the available water capacity for the Capay soil has been estimated to be approximately 9 inches. The Stomar clay loam is described as very deep, well-drained soils occurring on nearly level ' terrain for both offsite properties. According to the Soil Survey, the surface layer typically contains grayish brown clay loam approximately 26 inches thick, and has a massive structure. Soils are described as being mildly alkaline. The subsurface is described as Gay with some lime ' masses present. Structure in the subsurface is sub-angular blocky. Soil permeability has been reported as slow and with reported ranges of 0.06 to 0.6 inches per hour. Runoff is reported as slow and the hazard for water erosion slight. The estimated rate of water intake in irrigated areas is 0.5 inch per hour. Based on measured soil textures, available water capacity for the ' Stomar soil is estimated to be approximately 10 inches. Both Capay and Stomar soils are reportedly used for agricultural purposes (NRCS, 1992) and are predicted to grow approximately average yields of hay, corn, sugar beets, and tomatoes. These soils are also reported to be able to maintain rangeland plant communities. 5.1 Jepsen Webb Ranch Soil Investigations Two soil investigations have been performed at the Jepsen Ranch property, including a CPT and HydropunchTm study and in-situ soil profile sampling.The CPT investigation, described here, yielded information concerning subsurface soil type and characteristics. Soil layers are differentiated based on resistance measurements obtained from the CPT drilling equipment. ' In-situ soil profile sampling includes observations from the surface to 6 feet bgs. 1° Reclamation Report, Page 13 ' Musco Family Olive Company ffds-BruWUdrrin¢obNTA20109 muuwNvelp}ieports4eGamaean MM .fWawbw repMt 98.12.0E.dw
