166 MULTIPLE PURPOSE RIVER DEVELOPMENT 



Storage sites seems unlikely without a significant shift in the com- 

 munity's values. The community would need to sanction the 

 transfer of public assets to private ownership, resulting in estab- 

 lishment of the legal right to exact compensation for factor services 

 rendered downstream, whether to private or federal beneficiaries. 

 This would involve competing values which the legal and political 

 process during the past half century has seemed loath to sacrifice. 

 In the Hells Canyon case, however, these questions of direct inter- 

 dependence between headwater storage and federal downstream 

 installations were relatively minor considerations, one may infer, 

 as compared with the problem of the sheer size of the development 

 relative to the Idaho Power Company system. 



Note to Chapter V 



Data on which the analyses of Chapter V were based were 

 obtained from the record of the Federal Power Commission hear- 

 ings, In the Matters of Idaho Power Coynpany; Project No. 1971, 

 No. 2132, and No. 2133, on file with the FPC in Washington, D.C. 

 The voluminous records contain many differing estimates for the 

 same items, because different assumptions were employed in deriv- 

 ing estimated magnitudes. The selection of estimates employed in 

 the analyses in Chapter V was governed by a desire to obtain com- 

 parability of data as among the three plans of development 

 reviewed, and to use estimates which enjoyed the sanction of a 

 consensus of expert witnesses. A detailed explanation of data 

 employed for each of the significant categories is given below.

Constructioji Costs. Estimates of at-site construction costs were 

 taken from FPC Staff Brief, Appendix B, Table 14, line 14. These 

 data on construction outlays reflect the adjustments required to 

 make the estimates comparable as among the three plans of devel- 

 opment. Since no estimates for construction outlays in connection 

 with downstream generating facilities were made by the FPC 

 staff, the data presented by Witness Cotton were employed; these 

 were consistent with a consensus of expert witnesses as to the 

 anticipated depletion of stream flows resulting from additional
