U <br />2.04.7(1)(b) <br />(v) The quality of the subsurtace water in this case is the same <br />as the quality of the water in the Rollins Sandstone and Springs G-26A and G-26B <br />which is tabulated on pages 2.04-30hh and 2.04-30ii respectively. <br />(b) The springs in Lone Pine Gulch are located in an area where the <br />gulch is generally in an east west orientation. Therefore, the springs are below a north <br />and a south facing slope. The soil in the two slopes are quite different. The soil on the <br />north facing slope is Fughes loam. Permeability is slow, and water capacity is high. <br />The soil on the south facing slope is Torriorthents-Rock outcrop, sandstone, complex. <br />Permeability is moderate to rapid, and available water capacity is moderate to low. <br />Based on the characteristics of the soils, it is unlikely the springs are being recharged <br />from the south facing slope. <br />The most likely source of water for the springs is either the north <br />facing slope or a combination of the north facing slope and flow from the alluvial <br />material in the bottom of Lone Pine Gulch. <br />Hydrological Monitoring Plan <br />The Operator has implemented a hydrological monitoring plan consisting of the <br />following major components: <br />• Drainage and sediment control plan <br />• Groundwater monitoring wells, springs and visual inspection <br />• Quality control on well sampling and analysis <br />L~ <br />Drainage and Sediment Control <br />All surface drainage is routed to a sedimentation pond as shown on the Facilities Map <br />(Map 10). The hydrological monitoring of the surface drainage consists of analyzing all <br />discharges from the sedimentation pond as required by the Operators Colorado <br />Department of Health, CDPS General Permit No. COG-850015. <br />mR-as <br />~R N -0 4~ <br />2.04-29c <br />Rev. 11 /02 <br />/)PfROVEl~ ~i/ry/o3 <br />
