million tons with annual production expected to range from about 1.5 million to 2 million <br /> tons. Mining will be conducted in two phases with excavation beginning in the <br /> northwest area of Phase I. Excavated material will be transported to the vested Tracy <br /> Rock plant by scrapers across MacArthur Drive. Excavation activities will typically <br /> occur from 6:00 am to 6:30 pm Monday through Saturday, and could occur from 6:00 <br /> am to 10:30 pm during times of peak demand. <br /> Topsoil Management <br /> Overburden will be removed as mining progresses within each phase. The overburden <br /> removed will be placed as a berm around the edge of the excavation, be placed as a <br /> part of reclamation, or will be stockpiled (see mining plan for location of stockpiles). <br /> When distinct soil horizons are present, topsoil will be segregated by defined A, B, and <br /> C soil horizons. During reclamation the soil will be placed with the A atop the B, the B <br /> atop the C, and the C atop graded overburden. Topsoil stockpiles that will not be <br /> utilized within one mining season will be planted with a vegetative cover or will be <br /> protected by other equally effective measures to prevent water and wind erosion. At <br /> the conclusion of mining, all overburden and topsoil will be replaced to prepare the site <br /> for agricultural production. <br /> The recommendations provided by Dellavalle Laboratory, Inc. for soil management will <br /> be followed. <br /> Slopes <br /> A geotechnical analysis completed by Kleinfelder, Inc. concluded that mining slopes will <br /> be stable at 1 '/z :1. Slopes will be reclaimed to 2:1 or flatter. Any temporary mining <br /> slopes exceeding 50' in height will require a 12' wide terrace cut to be placed in the <br /> slope wall. The reclaimed floor will be an average of 28' below original grade; <br /> therefore, no benches will exist upon reclamation. <br /> Water Requirements <br /> Aggregate material will not be processed at the project site, thereby eliminating the <br /> need for water. However, water trucks will be utilized at the site for dust control <br /> measures and to water the newly planted vegetation. <br /> 6 <br />
