t <br />WAT6e BBQSIYffiRIS Alm COIISm~'lIYE IISS <br />Figure B ie a schematic diagram illustrating water use and flow at the <br />mine and associated facilities; including sources of water, water use. <br />discharges and consumptive uses. Complete meter records of the water <br />meters shown on the diagram are available for almost all of 1985. The <br />records have been amended to reflect a full calendar year for 1985 and <br />those numbers have been used in the analys <br />i <br />~ <br />~f water use at the mine. <br />y~~',~ <br />~,',' <br />"~C <br />g~ <br />The Southfield Mine ie entitled to 60 <br />llons per minute from the Corley <br />Mine Well. which tape water in the old Corley Mine (Rex Carbon seam). <br /> <br />This is a decreed water right with uses listed as other- in Caae No. L" <br />W-642. The Rules and Regulations for Division 2 ordered by the State <br /> ~ <br />Engineer's Office would allow the Corley Mine Well to pump three days out ~ <br /> <br />of seven per week. This schedule would allow an annual diversion of 41.4 <br />acre-feet. The Corley Well was used when the mine was first started. As <br />mining progressed and more water wsa produced by the mine, necessitating <br />mine dewatering by the North Entry Well and other sumps, the mine has had <br />to rely less on the Corley Mine Well for fulfilling water requirements. <br />Southfield Mine dewatering ie currently being accomplished by underground <br />pampa and the North Entry Well. The North Entry Well pampa mine inflow to <br />the first fresh water pond (see Figure 8). Corley Well water also can be <br />pumped to the first fresh water pond. Water from this pond is distributed <br />via the second fresh water pond to all phases of the mining operation ae <br />needed. During the past few years. the Corley Well has not been used as a <br />water source because ae a practical matter, enough water for all uses has <br />been available from the North Enr*v wP~l and underground pampa. Recently, <br />Energy Fuels Coal. Inc. has re-activated the Corley Mine Well for <br />consumptive use water only and is discharging North Entry Well water to <br />the stream system. Because the North Entry Well is not adjudicated for <br />mine use. plane are to continue using the Corley Mine Well for mine use <br />for dewatering and <br />supplementary water use purposes. <br />- 15 - <br />
