EXHIBIT C MINING PLAN Mining will commence in 1999 as soon as all permits are in hand and may continue for long as ten years. The mine plan calls for the removal of the waste dump material with a front end loader and processing on site. Portable screens and crusher, if necessary, will be used on site to process the waste dump material for use as a road material. Road material is the primary and only product to be mined at this site. The gravel product will then be stockpiled on site prior to loading into county trucks for use on nearby roadways. At this time, it is planned to sub - contract the gravel sizing and stockpiling in 30,000 ton increments for annual usage on county roads. The first parcel described in the legal will be processed first. The 3.4 acre parcel may contain up to 180,000 tons of gravel. During the first 30000 ton increment mined, it may necessary to utilize the upper second (pit #2) parcel for stockpiling of material. As the pit face progresses east to west, the finish material will be stockpiled next to the working face. As the waste material is processed, a 2% grade will be maintained from the pit entrance to the working face to minimize any sediment being carried out of the pit area during rain events or snow melt. There is no soil horizon developed at the surface of waste dumps, although trees and shrubs will have to be removed prior to excavation. As mining of waste materials progresses to the original surface(s), any organic material or soil horizons will be left in place or stockpiled for reclamation at the end of mining. The location of topsoil or organic matter stockpiles, if encountered, is shown on the Mining Plan Map. Along the contact will the natural slopes, the waste dump material will be graded to no steeper than 3:1, H:V, and stabilized via contour rilling to minimize erosion of the newly exposed dump material and(possibly) original soils. Along the toe of the existing unstable waste dump in proximity to Howard Creek, it may necessary to utilize back -hoes or excavators to remove waste dump material with minimum disturbance to vegetation along Howard Creek, especially the well developed stands of Cottonwoods. During mining operations, a four foot tall berm of waste materials will be left along Howard Creek to maintain isolation of Howard Creek flows into the mining area and restrict water flow from the mining area into Howard Creek. After mining, the floor and slopes of the mining area will be seeded with a mixture of native grasses, shrubs, and forties. The affected land boundaries were carefully located to keep mining operations out of any streams, springs, or Howard Creek proper. The exposed face(s) of the waste dumps do not appear wet or show evidence of seeps or water flow. Where water flows do cross the waste dump materials (west of the permit boundaries), the mining operator has elected to not disturb that area and terminate mining in that direction. (Western limit of Pit #1). In the event that mining operations intersect a flow of water or spring that was covered by the waste dump construction and not visible at this point in time, a water quality control plan will be followed. The goal of the plan will be to isolate, decant, and return the water flow back to Howard Creek drainage in a manner that will minimize water quality impacts. This may include the construction of small sediment ponds, berms, and/or ditches to maintain good water quality in the drainage during and after gravel extraction operations. Under no circumstances will equipment be permitted to operate or travel
