<br />' exceed 25 or 30 feet In areas where mining excavation exceeds 10 feet, mining will occur in <br />lifts, and the high wall will be benched or sloped as necessary to maintain a geotechnically <br />stable configuration Mining for Phase I will proceed northward toward the central portion of <br />the pit boundary, uansitioning to Phase II which proceeds easterly, removing the west end of <br />the existing ridges or fingers while maintaining final pit floor elevation Phase III will consist <br />of the removal of the east ends of the ridges ro achieve final grading configuration Emphasis <br />' is placed on the north and eastward mining directions in Phase I and II, enabling the operator <br />to reach pit depth and utilize the existing terrain features to minimize visual impacts. The <br />ends of the two eastward ridges or fingers will remain in place as natural knolls or knobs, <br />' resulting in amore natural foreground for a westward view angle. <br /> As mined, the material will be processed through a portable screen deck operating within the <br />' disturbed pazcel area. Screened materials will be stockpiled sepazare and be transported from <br /> the stockpile as necessary. Graded stockpile and screen deck locations will vary within the <br /> permit area as the mining plan progresses. Once an area has been graded and reseeded for <br />' fatal reclamation, it will not be used for mining, screening, or stockpiling. This process will <br /> establish 5na1 configuration of a gently sloping (1050) pit floor which readily transitions into <br /> a lower (35'0) pit floor and to the undisturbed natural azeas on the east side. A 3H:1 V slope on <br /> the west and south sides will minimize potential erosion damage and is compatible with both <br />1 existing contours and intended future use of rangeland. <br />' C. It is expected that average annual consumption rates will be approximately 75,000 tons per <br /> yeaz. This figure is influenced by market demand and could be more or less. Using this <br /> average and the anticipated quantity of gravel, the life expectancy of this mine is estimated to <br />' be ten years. Actual completion time being dependent on sales, the permit is requested for the <br /> life of the mine. Beginning date of operation is estimated to be the Fourth quarter of 1993 <br /> depending on the necessary permits required to commence extraction. <br /> D. Mining operations will be limited [o daylight hours between 7:00 A.M. and 6:00 P.M. , 6 <br /> days per week (Monday-Saturday). Limited market demands may require shorter workdays or <br />working weeks. Weather permitting, operations may occur to some extent during any or aIl <br /> months of the year. Night operations will not be allowed. The estimated time table for each <br /> phase ranges from 2 to 4 years. The time table for each phase will overlap due to reclamation <br />' occurring in one area and mining in an adjacent azea <br /> E. The mining operation will require a staffing of 2 to 5 employees to operate scales, loader, <br />' dozer and screening equipment Additional employees will be required on a random or part <br /> time basis to operate the water truck and the diesel service [tuck. Hauling may be <br /> accomplished by independent contractors, the operator and/or government entities. <br /> <br /> F. No usage of on-site water resources is planned. Water for dust control and fire protection <br /> shall be legally obtained from offsite potable sources and scared in a portable water treiler. <br /> Potable water for employees will be transported to the site daily by the operator in adequate <br /> quantities to serve staffing needs. <br /> Sanitary facilities on-site shall consist of a portable chemical toilet located within the curnnt <br /> mining parcel. <br />' P-5 <br /> <br />
