Attached is a copy of the cover letter for TR-47. On page 3 of the TR-47 cover letter, Bowie Resources states that <br />the dead storage in the proposed sediment pond HC is 0.03 acres and that the evaporative loss in pond HC amounts <br />to 0.08 acre-feet per year. Bowie Resources further states that the total evaporation estimate from all of its ponds is <br />being lowered in Technical Revision No. 47 from the currently approved 5.20 acre-feet per year down to 4.88 acre- <br />feet per year in order to match the approved water augmentation plans. Attached is a copy of TR-47 revised page <br />2.04-66 which shows the revised pond evaporation estimates. Due to this reduction in the total annual pond <br />evaporation estimate, the total estimated water consumption use was also reduced in TR-47 from 323.8 acre-feet <br />down to 323.5 acre-feet. This does not include the water needed for drilling the vent shaft, as described further on <br />page 3 of the TR-47 cover letter. <br />For additional information or to provide written comments, contact the Division of Reclamation, Mining and <br />Safety, Room 215, 1313 Sherman Street, Denver, Colorado 80203, (303) 866-3567.
