~~ <br />~J <br />~~ <br />2.04.11 <br />TR-027 <br />~ PPi20VED $~azl of <br />The Wash plant will add 69.0 acre feet to the estimated consumption at the <br />Bowie No. 1 mine. See discussion below regarding actual consumptive use. <br />The Bowie No. 2 Mine obtains its dust suppression and sanitary water from <br />the Deer Trail Ditch via the new pump station located on the Deer Trail ditch. <br />During the 2002 calendar year, the Bowie No. 2 Mine consumed 198.36 AC- <br />FT of water in order to produce 5,386,000 tons of coal. Pond evaporation is <br />for 2002 was estimated at 3.05 AC-FT per year. The addition of the <br />estimated pond evaporation to the mine consumption produces a <br />consumptive use of 201.41 AC-FT of water for the 2002 year and is less than <br />the estimated 234.6 AC-FT estimated in the permit application. This usage <br />indicates that water for dust suppression and fire prevention at the Bowie No. <br />2 Mine is currently averaging approximately 36.8 AC-FT per million tons of <br />coal. At a production level of 6.0 million tons per year, water consumption <br />should be about 223.85 acre-feet per year. The applicant has undergone a <br />Section 7 consultation for 256.90 acre feet per year. Please refer to <br />Biological Opinions dated Sept. 3, 1996, Dec. 10, 1999, Oct. 23, 2001 for <br />123.6, 113.0 and 20.3 acre-feet respectively. <br />As shown above, the addition of the wash plant will increase the estimated <br />consumptive use to 325.9 acre-feet. Therefore, a Section 7 consultation will <br />be required of an additional depletion of 69 acre feet for the addition of the <br />wash plant. <br />The applicant holds a water right to use 0.5 cfs decreed to the Deer Trail <br />Ditch for power and mining purposes with the. date of appropriation of <br />February 15, 1907. Full time use of this water right would supply the mine <br />with 362 acre-feet of water. Therefore, the applicant has water rights <br />adequate to supply the estimated water consumption for the Bowie No. 2 <br />Mine. <br />2.04 - 70 - 06/03 <br />
