III IIIIIIIIIIIII III <br /> s� <br /> E)GHBIT G <br /> WATER INFORMATION <br /> CLIFTON WATER GRAVEL PIT <br /> The historic drainage of the site is to the southwest with the surface drainage flowing towards the <br /> Colorado River. A flood control berm about three feet high has been constructed along the north <br /> bank of the River which prevents surface water from draining into the River. A portion of the <br /> t surface water along the north property line drains into the Elam-Bounds gravel pit. When mining is <br /> completed a pond will be formed with the water surface elevation approximately four to five feet <br /> below the present ground elevation. All surface drainage immediately adjacent of the site will drain <br /> ' into the resulting pond. <br /> The site is located adjacent of the Colorado River which contributes to the water table being <br /> ' approximately five feet below the existing ground elevation. Dewatering will be required to mine <br /> the sand and gravel deposit. Ground water will be pumped to the Colorado River. <br /> ' Dewatering of the pit will be done to meet the requirements of the Discharge Permit issued by the <br /> Colorado Department of Health. Depending on the silt content of the gravel, a settling pond may <br /> ' be required prior to discharge to the River. <br /> Best management practices such as the use of silt fences and straw bails will be used during <br /> ' dewatering and around overburden piles to control sediment during mining and reclamation. <br /> There are no known potable water wells near the permit area. The area is served domestic water <br /> ' by the Clifton Water District. The salinity of the ground water is to high for domestic water. <br /> A Well Permit has been applied for from the Colorado Division of Water Resources. As required <br /> ' by the State Engineer, a copy of a 600 Foot Well Spacing Statement is attached for your <br /> information. <br /> ' The estimated flow during dewatering will be from 200 to 800 gpm depending on the time of year <br /> and the amount of previously mined area requiring dewatering. <br /> ' The estimated water required during the mining operation is 3000 gallons per day and <br /> approximately 300,000 gallons annually. Ground water has been filed for as part of the Well <br /> Permit with the Colorado Division of Water Resources. <br /> 1 <br />
