EXHIBIT B— SITE DESCRIPTION <br /> Map B 1 —Vicinity Map and Neighboring Properties <br /> WATER INFORMATION <br /> 1. Surface Water General Discussion <br /> Existing stormwater on the terrace either infiltrates through the gravel or runs off through the un- <br /> named drainages. Surface water within the disturbed area will be collected during mining in the <br /> northwest portion of the mining area and will infiltrate.No sediment will be allowed to leave the <br /> site and cloud any downstream waters. The site will not affect existing water rights, since the pit <br /> will not expose groundwater and will not store stormwater for more than 72 hours. <br /> After reclamation, stormwater encountered in the mining area will continue to infiltrate or <br /> evaporate. <br /> 2 Hydrology and Sediment Control for Mining <br /> Water that is encountered in the pit will not be released from the site. The only water that will be <br /> found within the disturbed area is stormwater runoff and water hauled to the mining area and <br /> used in processing and for dust control. During topsoil stripping, ditches will lead to the mine <br /> area,to ensure that no runoff leaves the site. The ponds and bermed areas will contain the 100 <br /> year runoff from the area that drains to it. Once the excavation of the pit has started, all water <br /> from the disturbed area will drain to the bermed pit and cannot leave the site. <br /> 3. Groundwater <br /> Since the test pits did not show groundwater and there are no visible seeps or springs, <br /> groundwater is not expected to be encountered during mining. While no groundwater is <br /> anticipated to be exposed by excavation, if it is exposed, excavation will cease at an elevation of <br /> 2 feet above the groundwater level. <br /> 5 Water Consumption for the Operation <br /> The Pit is on an elevated terrace and there is no groundwater on the terrace. This is known from <br /> existing operations on the terrace further north of this site and the lack of springs emanating from <br /> the base of the sandstone anywhere on the site. There is very little moisture in the sandstone and <br /> will evaporate as it is mined. <br />
