<br />) <br />7. Nine Mil~s of Tunnel <br /> <br />- 2 - <br /> <br />To implement this plan it is necessary to build a nine mile tunnel from <br />Curecanti to the high water mark of the Crystal reservoir. U. S. Bureau <br />of Reclamation figures indicate that a 12.5 tunnel would be large enough. <br />From the U. S, Bureau of Reclamation tunnel estimating chart 103-D-375. a <br />12.5 foot pressure tunnel would cost $130 per foot, based on 1940 costs. <br />An ad:li tional 115 % was allowed to bring the costs up to date plus an 00- <br />ditio:~al 25% for engineering and contingencies, making a total of $1,844,700 <br />per roUe. <br /> <br />B.

Bureau of Reclamation report. <br /> <br />11. IndustriE,l Benefits <br /> <br />No credit allowed as yet, but some credit surely should be given here. <br /> <br />12. Domestic Use. <br /> <br />No credit allowed as yet, but some credit surely should be given here. <br /> <br />13. Recreation <br /> <br />No credit allowed as yet, but some credit surely should be given here. <br /> <br />14. Salvage Value <br /> <br />14.5% estimated salvage value is the same percentage as U. S. Bureau of <br />Reclamation estimated salvage value of 940,000 A.F. reservoir and power <br />facilities. <br /> <br />15. Annual Costs <br /> <br />o&M and replacement costs were determined from a direct ratio between the <br />costs ,shown in the U, S, Bureau of Reclamation report, and the costs shown <br />in thi:> report. For exW:,;Jle, power plant costs were determined as follows: <br />U. S. Bureau of Heclamation total cost $>5,735,000 <br />Revised' total cost 8,831,900 <br />Ratio = 1.S,> <br />OIcM, U. S. lJureau of Reclamation 96,000 <br />Revised - 96,000 X 1.54 = 136,320 <br />Replacement, U, S. Bureau of Reclamation 45,800 <br />Revised - 45,800 X 1.54 = 65,036 <br />All other C&M <n d replacement costs computed by same method. <br />
