would be expected to be low and significantly reduced from existing conditions. This is a significant impact. Alternative 4: . No Proiect The surface soil at the project site would not be disturbed under this alternative, except possibly by conventional agricultural practices (i.e., disking and plowing). The impact of soil disturbance would be less-than-significant. Mitigation Measure 4.2-8a (Alternatives 1, 2, and 3) Prior to commencement of mining, the proponent shall be required to submit a soil reconstructionlanprepared b Y a qualified soil scientist which establishes specific A procedures for the amendment of soil used for agricultural reclamation at the project site.. The plan shall present recommendations for suitable soil texture and the types and application rates of soil amendment products. At a minimum, the upper three feet reconstruction surface soils shall have an organic content of one percent. The plan shall demonstrate that potential migration of amendments to surface water or groundwater shall not result in reduction of water quality. In addition, the plan shall provide for procedures and specifications for a soil fertility and crop productivity monitoring program for test plots within the Phase 1 mining/reclamation area. Productivity goals shall be established on the basis of crop productivity of adjacent lands currently under agricultural production The soil reconstruction plan shall be submitted to the Development Services Division and Office of the Agricultural Commissioner for review and approval. Mitigation Measure 4.2-8b (Alternatives 1, 2, and 3) The proponent shall submit soil sample analysis from an independent laboratory for two-foot and four-foot depths (five random sample locations per 900 acres) of reclaimed soil. The analysis shall demonstrate that a minimum of 85 percent of the soil samples meet the specifications presented in Mitigation Measure 4.2-8a. Mitigation Measure 4.2-8c (Alternatives 1, 2, and 3) The reclamation plan shall be modified to specifically require segregation (into stockpiles) of the A- and B-horizons of the existing soils during soil removal. The A- horizon soils shall be reserved to serve as the uppermost layer of soil in areas of the project site to be revegetated. The proponent shall maintain a master map of stockpiled soils, identifying the location and quantities of the segregated soils. Level of Significance After Mitigation: Implementation of Mitigation Measures 4.2-8a through 4.2-8c would reduce the effects on agricultural soil resources and capability to a less-than-significant level.
