MINING PLAN -The Mining Plan Map found within Exhibit C depicts the proposed permit boundary, mining areas, site features, and the location of other uses ancillary to the operation. Operations will occur intermittently throughout any given year depending upon public demand for the resource. Approximately 199.7 acres of the 264.63 acre permit boundary are identified for use as sand and gravel extraction. Mining will be conducted in seven phases. The first phase will also serve as a staging area during the life of the mining operations and will include the following activities: • Processed material stockpiling • Portable scale • Recycled materials stockpiling • Office and lab trailer parking • Employee parking • Portable fuel storage • Equipment parking and maintenance • Tool storage • Portable toilet Preliminary sub-surface irnestigations together with soil survey studies within the identified mining area revealed the nature of the aggregate deposit. The average eight to ten foot thick sand and gravel layer is a terrace deposit overlaid with two to four feet of overburden soil. The resource is situated on top of a relatively flat layer of stony clay stratum. Ground water was not encountered in any of the excavations. The first step of the mining process will be the removal of zero to six inches of topsoil. The topsoil will be removed using scrapers, loaders and dump trucks and stored in stockpiles near the identified mining area and will be used for during the reclamation phase of the mine. Once the topsoil has been removed, the overburden removal process will begin. As was the case with the topsoil removal, overburden will be excavated using scrapers, loaders, and dump trucks. Overburden will also be stockpiled near the extraction area in separate stockpiles from the topsoil. To prevent erosion, the stockpiles will be hydro- seeded within 12 months of establishment at a rate of 15 bulk pounds per acre. The seed mix consists of the following: Shee Fescue 1.5 #PLS/Ac. Pubescent Wheat rass 1.0 #PLS/Ac. Crested Wheat rass 1.5 #PLS/Ac. Orchard rass, Paiute 1.5 #PLS/Ac. Thicks ice Wheat rass 2.0 #PLS/Ac. Winter Wheat 1.0 #PLS/Ac. Slender Wheat rass 2.0 #PLS/Ac. In addition to the seed the following materials will be utilized: Material Rate/Ac. "Biosol" Fertilizer 1100 lbs. Fiber Mulch 200 lbs. Tackifier 2001bs. Straw Mulch a rox. 100 bales Herbicides are applied annually to control weed growth on the stockpiles, (See Exhibit E). All of the stockpiled overburden will ultimately be used in the reclamation process. All of the stockpiled overburden will ultimately be used in the reclamation process. Setbacks between the mining area and the permit boundary have been maintained to protect the integrity of the adjoining land. The sand and gravel mining process will be conducted using loaders, and/or excavators. Blasting of the resource is not necessary. Haul trucks will transport the resource to the nearby crushing and screening area located on the mine floor, or the ultimate delivery site. The crushed and screened material will then be loaded, transported and stockpiled nearby on the mine floor or hauled Rev. 05!18/04 Y
