6.4.7 Exhibit G <br /> Water Information <br /> Mining is expected to have no impact on the prevailing hydrologic balance. <br /> Groundwater will not be exposed, and stormwater will not leave the site. The site will not <br /> discharge stormwater or process water drainage. <br /> According to the Division of Water Resources HydroBase Data Viewer, groundwater <br /> near the site is anticipated to be approximately 255 feet in depth (see below). The mining <br /> operation will only mine to a depth of 20 feet. <br /> Runoff occurs as overland flow to natural drainage ravines in the vicinity. Stormwater <br /> best management practices such as waddles, straw bales, and perimeter berms will be placed <br /> to effectively manage stormwater. Historic flow will be maintained during mining. <br /> Consumptive use of water may occur as dust suppression on the haul road and affected <br /> areas. All Rite Paving and Redi Mix will purchase the necessary volume of water from an <br /> appropriate supplier. The amount required for this is undetermined at this time. <br /> The permittee will complete a stormwater management plan. Diversionary berms and <br /> impoundments will be constructed as recommended by the Water Quality Division. <br /> D 0 Map Viewer <br /> + <br /> St—ture(Adm.NDecreed) -- <br /> Q Stwdure IP—ts of Inte—! - <br /> 0 Well APPLcat— - - - <br /> Enul Permit <br /> 0 Gra+nd Water <br /> S.d—Wale,C-1 Condltiom <br /> 5urface Wale,Station"Voticl - <br /> Ll—tock Water Tank/Erosion <br /> Control Dam <br /> Dam Safety 't <br /> Wddland Eire <br /> Climate SO— <br /> Climate I'^" <br /> .ydlography <br />
