• 2.04.11 <br />• <br />PR-06 <br />~/1 s/o z <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 />The pump station was fully operable and metered during the 2000 calender. <br />During the 2000 calendar year, the Bowie; No. 2 Mine consumed 158.95 AC- <br />FT of water in order to produce 5,054,000 tons of coal. Pond evaporation is <br />for 2000 was estimated at 2.0 AC-FT per year. The addition of the estimated <br />pond evaporation to the mine consumption produces a consumptive use of <br />160.95 AC-FT of water for the 2000 year and is less than the estimated <br />234.6 AC-FT estimated in the permit application. This usage indicates that <br />water for dust suppression and fire prevention at the Bowie No. 2 Mine is <br />currently averaging approximately 31.8 AC-FT per million tons of coal. At <br />a production level of 6.0 million tons per year, water consumption should be <br />about 190.8 acre-feet per year. The applicant has undergone a Section 7 <br />consultation for 236.6 acre feet per year. Based on historic water <br />consumption records, the applicant does not believe its consumption will <br />exceed the 236.6 acre feet per year, so a Section 7 consultation should not <br />be required for the addition of the loadout and a the production increase to <br />6.0 million tons per year. <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 - 08/01 <br />
