<br />COLORADO RIVER STORAGE PROJ,ECT <br /> <br />19 <br /> <br />available and actual ~osts of past investigations and construction are <br />included. ' <br />(3) Operation and Ipaintenance cost estimates are based on 1954-56, <br />price levels, Replacement costs are based on current construction <br />cost estimates. ' <br />(4) A lOO-year period is used in the benefit-cost and cost-allocation <br />analyses. , <br />(5) Water supply, power production, and related studies are based <br />on the assumption that average annual stream deple,tions from projects <br />in the upper basin will increase from an average of 2,550,000 acre-feet <br />at present to an average of 5,500,000 acre-fee,t by the end of the' <br />lOO-year period from fiscal year 1963 through fiscal year 2062. In <br />addition depletions dile to evaporation losses from the 4 anthorized <br />storage units are estimated to average 691,000 acre-feet at, the end <br />of the 100-year period, <br />(6) Benefits for ns~ in the benefit-cost and cost-alloeation analyses <br />are determined for all project purposes in accordance with existing <br />proeed\ll'es of the Bl)reau of Reclamation. Irrigation benefits are <br />evaluated as direct, iI]direet, and public and are based on anticipated <br />agricnltlll'sl condition~ without and with the development, Benefits <br />from power snd muniripal and industrial wat,er are based on the cost <br />of the most economicaI single-purpose alternative that is likely to he <br />deve.Ioped in the abrlence of the proj ect and thst would provide <br />benefits cOUlpamble to those of the project, Flood control, reereation, <br />and fish and wildlifc benefits are evalUl1ted by the Corps of Engineers, <br />National Park Service, and Fish and Wildlife Service, respectively. <br />(7) A 2H-pcrcent interest rate is used in the benefit-eost and cost- <br />allocation analyses, e.xcept that an interest rate of 6)) percent for <br />private financing is used in cstimating altcrnative power eosts and <br />annual power benefits: <br />(8) Taxes are inc.lu~ed in the estimated cost of the most economical <br />alternative for project power in evaluating power benefits. Accord- <br />ingly an amount, equal to the taxes is included in the eost of pl'Ojeet <br />power in benefit-eost ;comparisons. No provision for payment of a <br />tax equiva.Ient is mad~ in power repayment studies. <br />(9) All costs of plist investigations and construction costs paid <br />from contributed funds are excluded from the benefit-cost analysis. <br />Contributed funds and expenditures from the Colorado River develop- <br />ment fund are exclu$led from the cost allocation and repayment, <br />analyses. <br />(10) In the benefit,cost analysis a share of the cost of the storage <br />project is apport,joned to irrigation and other water-consnming nses <br />initiated subsequent t<)1949, the year the Upper Colorado River Basin <br />compact becsme effec~ive. <br />(11) Costs are allocated by the separable cost-remaining benefits <br />method except t,hat oply separable costs are allocated to recreatiou <br />and fish and wildlife, ' <br />(12) Repayment 0(011 reimbursable costs of units and partieipating <br />projects is based on a ~O-year period following compleHon of each unit, <br />project, or separable feature thereof, with appropriate development <br />perIOds in the case o~ irrigation. The exceptIOns to this are in the <br />repayment of the Pabnia and Eden projects for which repayment. <br />
