The final-sized and washed sand and gravel would be stockpiled by size over a recovery and blending tunnel. The finished construction materials would be a blend of different sizes of aggregate. After blending, construction on materials would be loaded on trucks for shipment. Production capacity is designed for the range 300 to 600 tons per hour on a single shift basis. The proposed processing plant would be operational for the duration of the project (56 years). Asphalt Concrete Production On-site asphalt concrete production would utilize on-site aggregate production and imported materials. Production would be on a single-shift basis starting at 5 Ann. Special production shifts may be required for night paving on major highway construction. Reclamation Subsequent Uses After Reclamation The project site would be reclaimed to agricultural uses (row crop production) following completion of the proposed project. The region has a good climate for growing row crops, as shown by the agricultural activity on the surrounding properties. As proposed, fines from the settling ponds would be used to reclaim the pit floor. This soil may be too low in organic matter for good row crop production. Organic matter would only build up in the soil with time and good agricultural practices. It is expected that agricultural production would improve each year for five years. The property would remain in the ownership of the proponent after reclamation. Reclamation Schedule Reclamation would be completed in phases. Phase 1 would be mined first, but would be the last to be reclaimed. After the Phase 1 is mined, it would become the location of future wash water ponds. The ponds are the last item to be reclaimed because they would be in use until all phases are mined and processed. Phase 2 would be reclaimed after mining is complete on that phase and mining has been started on Phase 3. Phase 3 would be reclaimed after mining is complete and Phase 4 has started. Each phase would be reclaimed with overburden, stripping, and wash water pond clays and silts from the previous phase. Phase 4 would use the silts and clays from the wash ponds to reclaim mined areas. Post Mining Topography The reclamation plan (Figure 3-5) shows all post reclamation topography, drainage and access to the reclaimed areas. All reclaimed slopes would be revegetated for erosion Draft Environmental Impact Report 3-16 ER-96-3
