3.Project Description yards of material (including shrinkage factor) would be needed to build out the slopes from 3/4:1 to 2:1. Revegetation Upon final grading,all disturbed areas will be revegetated. Topsoil from the stockpiles would be placed on all final reclaimed 2:1 slopes and would be revegetated with a non-irrigated hydroseed — mix consisting of 80 percent Zorro fescue and 20 percent rose clover.Pit bottoms would be graded smoothly and uniformly flat and revegetated with an agricultural crop. End Uses All reclaimed areas except for the slopes will be returned to land that can be used for agriculture. — Reclamation will be complete when the productive capability of the land is equivalent to or exceeds,for two consecutive crop years,that of the premining conditions or similar crop production in the area. The slopes will be open space. 3.7 List of Permits and Approvals - 3.7.1 Pending Approvals _ The SMARA was enacted in 1975, and mandates the California Department of Conservation, California Geological Survey (CGS)to identify and evaluate the mineral resources of the State, including sources of construction aggregate. One of the purposes of this mandate, and of SMARA itself, is to protect significant mineral deposits from potential loss due to incompatible land uses. Based on State Mining and Geology Board guidelines,CGS is authorized to map regions within — the State to classify areas with significant aggregate resources. The CGS Special Report 91-03,Mineral Land Classification: Aggregate Minerals of the South — Tracy Site, San Joaquin County indicates that different areas of the project site have various mineral land classifications. The eastern area of the project site has been classified as MRZ-3 (areas containing mineral deposits the significance of which cannot be evaluated from available — data),the southwest section has been classified as MRZ-2 (areas where adequate information indicates significant mineral deposits are present,or where it is judged that a high likelihood exists for their presence), with the remaining portions of the site being classified as MRZ-1 (areas — where adequate information indicates that no significant mineral deposits are present or where it is judged that little likelihood exists for their presence). SMARA requires the preparation of an acceptable reclamation plan and financial assurances for all surface-mining operations. Reclamation plans are developed to meet various performance standards for the protection of wildlife habitat, revegetation,recontouring,erosion control,etc. as well as to eliminate or reduce residual public health and safety hazards and minimize RMC Pacific Vernalis Quarry Mining and Reclamation Pojecl 3-26 ESA/203015 Draft Environmental Impact Report May 2006
