6.4.7 Exhibit G <br /> Water Information <br /> Groundwater will be exposed during mining operations and pumped from the site if <br /> needed. Any exposed water will be covered by existing LAWMA water shares available on the <br /> property. A 10-acre pond will remain throughout the mining and reclamation phases and will <br /> be augmented using the above-referenced LAWMA shares. <br /> Stormwater will not leave the site, as earthen berms will contain the drainage. The site <br /> will not 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 16-75 feet in depth (see below). The mining <br /> operation will only mine to a depth of 45 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, as well as for washing operations. The amount required for this is undetermined at this <br /> 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 />
