--:;J t- " .) W """" Plan Rank Alternative 5 Alternative 6 Alternative 1 Alternative 3 Alternative 4 Alternative 2 1 2 3 4 5 6 Alternative 5 was selected as the top ranked plan mainly because it meets the target objectives in a balanced manner with relatively few adverse environmental impacts. It can also be constructed in stages .with only one storage reservoir in phase one (this, of course, is the second ranked plan, Alternative No.6). Alternative 5 can also also be staged in a variety of other ways; for example, the recreat i on components coul d be phase one, one reservoir could be phase two, and the second reservoir could comprise the last stage. The primary reason that A lternat i ves 5 and 6 were ranked ahead of Alternative No. 1 is because Alternative 1 is a single purp.ose plan and therefore does not meet as many target objectives nor does it provide the range of potential benefits that can be provided by Alternatives 5 and 6. PUMPED-STORAGE AS A POTENTIAL FINANCING MECHANISM A preliminary evaluation of the basin topography concluded that a large number of potential pumped-storage sites exist in the study area. These sites were screened on the basis of the ratio of water conductor length to gross head which is an indicator of a potential project's economic attractiveness. Two projects; the 720 MW Needl e Poi nt No. 3 and 1000 MW Rocky Poi nt No. 2 projects were selected as attractive sites and were evaluated in greater detai 1.
