This order has been: <br /> <br />o <br /> <br />Initial Screening or pre-reconnaissance investigation <br /> <br />Hydrologic, water rights and operational analysis <br /> <br /> <br />Reconnaissance-level project designs and cost estimates and comparative <br /> <br />analysis and cost-yield relationships of alternative reservoirs and potential <br /> <br />reservoir combinations. <br /> <br />o <br /> <br />o <br /> <br />Recognizing that this study has covered only a limited number of the facets involved in <br />selection of projects for construction, no ranking or preference has been attempted. Instead, <br />efforts have been concentrated on developing reservoir water yields and project construction <br />...0 <br />cost estimates based on an approximately uniform level of investigation. <br /> <br />An initial screening of previously published information about environmental concerns <br /> <br />was conducted for each site with the objective of eliminating sites with "fatal flaws". No attempt <br /> <br /> <br />has been. made to suggest mitigation measures or evaluate the costs of complying with <br /> <br />requirements that result from environmental concerns. <br /> <br />Reservoir sizes have been selected to represent the maximum size that conforms with <br /> <br />the site topography, with some restrictions to limit the extent of reservoir-imposed relocations of <br /> <br />existing improvements. Generally, maximum yields from individual reservoirs fall short of <br /> <br />meeting Green Mountain Exchange Project objectives. Consequently, emphasis has been <br /> <br />placed on portraying combinations of reservoirs and estimating firm yield from the sites rather <br /> <br />than analyzing unit cost of yield for alternative dam heights at individual sites. Comparisons have <br /> <br /> <br />been carried out for the cost of yield from alternative reservoirs and alternative combinations of <br /> <br /> <br />reservoirs and for the cost of alternative conveyance system capacities. <br /> <br />1-5 <br />
