WATER INFORMATION <br />Exhibit G -AMENDMENT <br />Water Information <br />The only groundwater encountered in this operation is a supply of water for washing and dust control. <br />This water is obtained from a small pit excavated into the ground near the northwestern comer of the pit and <br />adjacent to (but not within) the floodplain of Running Creek. Water supply for this pit is from the alluvium. <br />Running Creek is generally a perennial stream, but in dry years the water level in the creek and alluvium has <br />declined to the point where very little water was available. As the operator (who is also the landowner) does <br />not have rights to drill a well, reliance on this water is somewhat precarious. <br />Recently, development of residential areas further upstream has increased the reliability of the flow in <br />Running Creek. Wastewater discharge from these developed lands has served to increase the stability of the <br />volume in Running Creek. Therefore, so long as that source is supplied to the stream, the reliability of wash <br />water for the operation will increase. <br />Utilization of this water is covered under an approved Substitute Water Supply Plan. No other <br />encountering or exposure of the groundwater occurs at the site. <br />Surface water through this area (current mining and the amendment area) is sparse at best. One very <br />shallow drainageway extends through the amendment area, but it rarely tames any water. This drainageway <br />connects with Rurming Creek a short distance downstream from the operation. Water that would flow down <br />this drainage will necessarily be diverted into the pit area, but it will all end up at the same place - in Running <br />Creek. <br />Although some closed pits necessarily develop when mining and these can retain some water, the high <br />permeability of the material allows ponded areas to dry quickly. That water simply enters the alluvium and <br />flows back into the primary alluvial aquifer along Running Creek. At the end of the operation, no closed <br />basins will be left. The bottom of the pit will slope very gently toward Running Creek and allow surface flows <br />to gently wind their way to the stream. Along the way that water will provide a supply for the vegetation in the <br />bottom of the pit. <br />Miller Gravel Pit Amendment (2007) Exhibit G Page 1 of 1 <br />
