• 2.04.11 <br />The effect the mine development will have on the endangered fish species of the <br />Colorado River Basin is usually determined by estimating the annual depletion of <br />water from the upper Colorado River caused by the mine development. The <br />consumptive use of water associated with the mine includes water used for dust <br />suppression, showers and personal use and losses due to evaporation. <br />The following water depletion estimate is prepared for the changes proposed by <br />permit revision no. 6. This permit action will allow longwall mining at a production <br />rate not to exceed 6.0 million tons per year. <br />A. The sole water source for the Bowie No. 2 Mine is water pumped from the <br />Deer Trail Ditch. Water is pumped from the ditch into a 500,000 gallon <br />water tank. The Operator has the right to pump up to 0.5 cfs (224.4 gpm) <br />from the ditch. <br />B. Water Depletion by Category: <br />Road dust suppression -The haul road at the Bowie No. 2 Mine is paved, <br />therefore virtually no water is used for dust suppression on the haul road. Other <br />• roads would include the road to the fan, coal stockpile area and the road to the <br />gob pile. It is estimated that an average of four each 3,000 gallon water tank <br />loads are applied to other roads each day for 8 months each year. This equates <br />to 8.9 acre-feet per year. <br />Pond Evaporation (lake evaporation) 31.38" net per year. <br /> Surrace Area Acres Annual Evaporative Loss A-F <br />Pond A 0.000 0.00 <br />Pond B 0.348 0.91 <br />Pond C 0.305 0.80 <br />Pond D 0.065 0.17 <br />Pond J 0.620 1.62 <br />Pond K 0.227 0.59 <br />Pond F 0.271 0.71 <br />Totals 1.836 4.8 <br />• <br />TR-47 <br />2.04 - 66 - <br />07/07 <br />~gPPRo~E~ <br />~ ~i7~'o7 <br />
