The Skull Creek Sand Project will not affect ground water. Mining will be too shallow to cause contact with any ground water or aquifer in the projected mining area. Surface water due to weather events will be affected. Figure 1 reflects two drainages that divide the permit area. The Miller Creek Drainage system takes in approximately 94.4 acres of surface within the affected lands with approximately 21.0 acres being affected by operations.45.6 acres are within the Skull Creek Drainage system with approximately 48.4 acres will be disturbed by mining operations. Figure 2 reflects those disturbed areas. Sediment from Drainage due to storm events, mining, and snow melt off will be controlled by two rock check dams as shown on Figure 3. The dams will be installed and constructed as reflected on Figure 3. Sediment that has backed up behind the dams will be periodically cleaned out so as to allow for continuous function of the dam.The placement of berms, as reflected on Figure 2, will help control water to flow in the direction of the rock check dams. Drainage is reflected on Figure C2, Exhibit C. There will be no wells, springs, stock water ponds, reservoirs, and ditches that will be affected by mining operations There is an aquifer under the proposed affected lands. This aquifer is used by the local residents and ranchers. The aquifer is well below the proposed mining operations making a barrier between the aquifer and final depth of mining. Uinta Mining projects that there will be no dewatering due to mining operations. However, Due to storm events there could be accumulations of water that would gather within the mining area. In the event that this occurs,the water would be pumped so that it may flow to a check dam prior to leaving the affected lands. Uinta Mining will have a need for water(approximately 12,000 gallons per week)to be used for dust suppression on the haul roads and at the mining location. Uinta mining has received a verbal consent to utilize water from the "Does Twist" well, along with pond water from Frances Lewis. That water source is approximately 1% miles west of the permit boundary. Uinta Mining is in the process of acquiring legal use of this well and that documentation be forthcoming. Skull Creek Ground Water Hydrology: Permit Boundary is a sub-set of the Skull Creek State School Section 36 outline. There are no ground water wells permitted or drilled within the permit boundary(Figure-4). Six ground water wells have been permitted and drilled within 1,000 feet proximity to the mine permit boundary. Static water level data from these six wells have been used to construct the Skull Creek Ground Water Hydrology X-Section (Figure-4)which shows location of three wells that are located in near proximity to the N-S X-Section Line and SWL's have been projected to the X-Section.
