EXHIBIT C Saffer Pit MINING PLAN A tracked dozer or front-end loader working from east to west will push the sand and gravel being mined in this operation into stockpiles. A front-end loader will then load the material from the stockpile into haul trucks. Some of the sand and gravel could remain in the stockpile for several weeks. The sand and gravel will be utilized in the maintenance and construction of county roads in District 2 of Lincoln County. Mining is already in operation in the existing area and will continue intermittently until the year 2028 or 2030 depending on the amount of material in the pit. Prior to removal of the sand and gravel in the new area, 3 to 6 inches of topsoil will be stockpiled for later use in the reclamation of the affected lands. These topsoil stockpiles will be hand seeded if necessary to stabilize the piles and prevent erosion. The I to 2 feet of overburden that underlies the topsoil will either be used as binder or stockpiled for later use in the reclamation_ These stockpiles will also be hand seeded as required for stabilization and to prevent erosion. The maximum size area that will be mined at one time would be from 5 to 6 acres; some reclamation will take place concurrently with the mining operations in order to keep the affected area at the 5 to 6 acre size. Judging from the amount of material available this pit should be in operation for about 10 to 15 years. The pit will be active but will be used fewer than 180 days per year.No water will be used to produce the sand and gravel being mined nor will any chemicals or explosives be used in this operation. The ranch road will be smoothed by the county using a motor grader. It will not be elevated but will be bladed to approximately twenty(20)feet wide to provide easier access to the site. A haul road into the pit will be also put in by the county road and bridge forces. The haul road enters the pit from the north side of the boundary. This haul road will also be approximately twenty (20) feet wide. Since these roads are not considered to be permanent typical Lincoln County specifications will not be used. Lincoln County utilizes somewhat modified Colorado Department of Transportation Specifications when constructing permanent county roads. The floor or bottom of the pit will slope gradually one to five (1 to 5)percent up to the east until it is necessary to put in the final finished slopes that would go up to the pit boundaries. The final slopes will be 4:1 or flatter. The over burden to be removed is a mix of soil and sand and gravel that gets sandier with increasing depth. The sand and gravel to be mined varies in thickness from 7 to 12 feet. The material that under lays the sand and gravel is a mix of clay and sand that turns to clay at greater depth- 3
