<br />EXHIBIT D-MINING PLAN <br />• Mining operations will oorrtinue as in the past with aggregate removal via bulldaser and front~nd <br />loaders. The front~nd loader will load a portable primary crusher located at the pit face. Topsoil <br />has been stripped to a depth of 8 to 18 inches and has been used to construct berms on the outer <br />edges of the affected properly. A 100-foot setback along the northem and eastern boundary will <br />be maintained and a 250-foot setback will be maintained on the weslem boundary adjacent to the <br />Mount Elbert Conduit easement. Ponderosa Pine, native grasses and topsoil will be maintained <br />with limited dsturbance within these setback areas <br />Aggregate extraction operations in the future will continue from the present pit location, in Section <br />7, with the extraction face progressing south towards the northem boundary of Section 18. <br />Phase I mining will continue to approximately 300 feet from the northem boundary of Section 18. <br />Phase II mining operations will relocate mining operations to the West Side of the de-silting <br />basins in Section 7. Mining will proceed south to approximately 300 feet from the northem <br />boundary of Section 18. Phase II I will proceed on the southern boundaries of phase I and phase <br />II. At this time aggregate processing facilities will relocate to the phase III area. The concrete <br />batch plant and portable asphalt concrete plant will remain in the phase I area. All mining <br />phases will mine up to 15 feet on the north /north east side and 3 feet on the south /south west <br />side of the Templeton Irrigation ditch (which passes through the property) and slope down <br />towards the bottom of the pit with a 4:1 slope. The ditch will be lined with cobble or an <br />appropriate lining to avoid erosion and seepage of the d'Rch. If erosion occurced the intermittent <br />flows may divert into the pit operations this is the reason for the ditch lining. The setback on <br />either side of the ditch will allow monitoring of this ditch throughout the mine life and beyond. <br />Preferably the topsoil removed for mining operations (4 to 12 inch depth) will be placed on the <br />east and west pit slopes as those slopes are finish graded, and as the mining progresses to the <br />• south. Prior to any slopes being ready the topsoil will he placed in berms at the edge of pit in <br />preparation to be placed on the slope face. These berms will be approximately 8 to 10 feet high <br />with actual height dependent on the amount of topsoil encountered in the various stripping <br />locations. The berms will be seeded and mulched to prevent erosion while waiting to be placed <br />on the final pit slope. A final maximum pit depth of 45 feet may be obtained if no water is <br />enoountered. Test holes have been dug to 45 feet and no water has been encountered. The <br />operators intention is to mine above the water table (the water table will not be exposed during <br />mining nor will subsurtace waters be impacted by mining operations. Final slopes within the <br />mined out pit areas will he no steeper than 4:1 (H:~. <br />Working stockpiles of construction materials for recycling may be located within the affected land <br />at various times. These products, inGuding broken asphalt and concrete, will be stockpiled prior <br />to processing to use in recyced construction materials (recycled asphalt or recyced road base <br />products). <br />Processing of gravel products inGudes primary and secondary crushing units (jaw, cone or <br />impact crushers), and screening systems to remove fines and size final products. Crushing and <br />screening equipment is portable, sited Gose to the mining face for loading with a front~nd loader. <br />Other process equipment on site indudes a gravel wash plant, with blade mill, wash screen, sand <br />classifier, sand screw, water pumps, and stacking conveyors. Also on site may be a concrete <br />batch plant and a portable asphalt mix plant (on an as needed, job tojob basis). Schematics <br />showing equipment capacities and rates are inGuded in this exhibit. <br /> <br />
