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 1230 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 and transport to the site for use. <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 />
