Box 1887 • 702 Gregg Drive• Buena Vista CO 81211 <br /> "ASPHALT,CONCRETE,&AGGREGATES' Phone: (719) 395-3790 Fax: (719) 395-3794 <br /> Exhibit D-Mining Plan: <br /> The detailed mining plan is laid out as follows: <br /> A. General Schedule of Operation-Excavation of material for this requested property (R.B. Pit) will <br /> commence when all permits are approved and will continue for approximately Thirty (25) years. The total <br /> amount of material to be used on site or removed is approximately 1,000,000 cubic yards. Extraction and <br /> processing operations will be in place between November 1 and March 31 yearly; however, load out <br /> and placement of material may occur throughout the year. <br /> B. Detail of Operation - Extraction will commence on the Southeast end of the proposed pit and move <br /> towards the Northwest. Topsoil will be removed and stockpiled for reclamation of slopes and pit floor. A <br /> shielding berm will be constructed out of onsite earthen materials as shown in Exhibit C. <br /> Material will be extracted by excavator, loader, and dozer. The mining will start at the ground level <br /> and advancing Northwestward until a 15-FT high wall condition is encountered. To maintain a safe <br /> working environment, a second bench will then be established starting at the 15-FT height. This bench will <br /> be mined until a 15-FT high wall is present. At this point, the mining operations will return to the first <br /> bench. The remaining phases will be mined in the same manner, as shown on the next page. At no point <br /> will mining activities be allowed to reach the groundwater level. As these benches proceed, the <br /> Northwest and Southwest walls of the property will be sloped to a 3:1 grade. This will keep a safe <br /> working environment in addition to ensuring adequate material for final reclamation without any <br /> additional material. The Northeast and Southeast borders of the pit are expected to 'daylight' to existing <br /> topography. <br /> Storm water control measures will include sloping all areas towards pit to retain possible runoff. <br /> Berms and pit wall sloping will be used to ensure all storm waters are retained on site. <br /> Final construction will include reclamation of the pit pursuant to Exhibit E. These reclamation <br /> activities will include slope stabilization, topsoil placement and seeding of all slopes and pit floor. <br /> Upon final reclamation, the land use is anticipated to be crop land. <br /> ACA Products, Inc• 702 Gregg Drive; PO Box 1887• Buena Vista,CO 81211 <br /> Phone 719-395-3790• Fax 719-395-3794 <br />
