Phase 2A: Mine Stage 1 of North Pit to groundwater. Backfill South Pit with <br /> overburden and fines to 15 feet above groundwater. <br /> Phase 2B: Mine Stage 1 of North Pit to design depth. Store groundwater in <br /> South Pit. <br /> Phase 3A: Mine Stage 2 of North Pit to design depth. Backfill Stage 1 of North <br /> Pit with overburden and fines to 15 feet above groundwater and replace topsoil. <br /> Store groundwater in South Pit. <br /> Phase 3B: Mine Stage 3 of North Pit to design depth. Backfill Stage 2 of North <br /> Pit with overburden and fines to 15 feet above groundwater. Replace topsoil. <br /> Store groundwater in South Pit. <br /> Phase 4: Stage 3 of North Pit remains as pond for agricultural use (elevation 75 <br /> feet). Stage 1 and Stage 2 of North Pit backfilled to 15 feet above groundwater <br /> (elevation 90 feet-Final Reclamation). South Pit backfilled to 15 feet above <br /> groundwater (elevation 90 feet). Replace topsoil. <br /> The final reclaimed pits will be backfilled to approximately ninety (90) feet AMSL for all <br /> disturbed areas (excluding the potential water storage pond for agricultural use), or_ <br /> approximately 80-90 feet below surrounding properties elevations. Reclaimed side <br /> slopes and pits will be replaced with eighteen (18) inches of topsoil that will be stored on <br /> site during mining. <br /> Project Size: <br /> 217.5 acres. Excavation will occur on approximately 155 acres and a processing plant <br /> will be constructed on approximately 10 acres of the project site. Reclamation will occur <br /> on all 165 acres of disturbed land. <br /> Project Location: <br /> The project site is located on the west side of Koster Road (east of the Delta Mendota <br /> Canal) between Vernalis Road (State Route 132) and Blewett Road, southeast of Tracy. <br />
