Processing Equipment Portable crushing and screening plant Portable wash plant Earth Moving Equipment Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth moving operations. Field conveyors and off-road haul trucks may be used as needed for mining operations. Miscellaneous An employee/storage trailer and office/scale house will be located on-site Dewatering pumps and generators and watering trucks will be used as needed. An azea for outdoor storage may be located near the office/scale house. As the majority of the mining taking place will be in the center of the previously mined area, very minimal topsoil and overburden is expected to be disturbed. As mining progresses, any remaining topsoil and overburden will be stripped with scrapers to expose the aggregate product below. Any disturbed soil and overburden material would be used on-site for reclamation; so long-term stockpiling of these materials is not anticipated. If overburden stockpiles aze necessary, they will be located as berms along the perimeter of the mine or within the proposed mining phases for future reclamation purposes. Mining of the aggregate will progress down to the underlying interbedded siltstone and claystone bedrock of the Laramie formation. The bedrock material is rippable and, if necessary, may be excavated and used for reclamation. However, since reclamation will occur concurrently with mining, it is not anticipated that bedrock material will be stockpiled long-term prior to use. The active mining face will progress to the south and east. A portable crushing plant may process aggregate. During mining and prior to reclamation, the phase walls will be a nearly vertical to %zH:l V slope. The aggregate material will be temporarily stockpiled or placed directly onto a conveyor system or haul truck units for transport to the processing area. Processing of material may occur in any of three ways. A portable processing plant may be set up in the bottom of the pit to size and screen material prior to it being hauled off-site for sales. The portable plant may be set up at the east end of the site for processing and sales on-site. Or, the material maybe hauled off-site as pit run for processing and sales at an adjacent operation. In both phases the side slopes for the resultant storage reservoir will be constructed as the mining phases are excavated. Although the interior phase wall will remain disturbed and vertical until the phase is mined out, the exterior walls of the phase will be backfiDed, graded to a 3H:1 V slope, and seeded as mining progresses, Once backfilling and grading has been completed in an area, the top of the scope and the side slopes above the anticipated average water level, will be seeded as soon as practicable (based on first available seeding season).
