Determine the Acceptibiljty and Nutritional Quality of Emergent <br />Halophytes as Forage for Livestock <br /> <br />This encompasses the testing <br />standard methods for valuation. <br /> <br />of STEP crops as feeds utilizing <br />Estimated cost: $170,045 <br /> <br />E. Evaluate the Potential Applicability of the STEP Process <br />Throughout the Colorado River Basin <br /> <br />This includes the field characterization of other saline sources <br />within the Basin as appropriate for assessing STEP process costs <br />and benefits. Estimated cost: $175,520 <br /> <br />The accomplishment of this work will require the combined efforts of <br />IBR, the Bureau of Reclamation, and the Department of Agriculture, <br />along with several Universities and private organizations, over the <br />next two years. Initial funding requirement for the field <br />investigations identified as A and B above is $448,280; these studies <br />must be completed before June, 1987, In addition, about $381,965 <br />will be needed for the remaining field investigations (C through E <br />above); these must be completed prior to initiating final design <br />preparation for commercial facilities. <br /> <br />Additional En~ineerin~ Investi~ations <br /> <br />Twenty-four additional engineering tasks are listed and briefly <br />described at the end of Chapter 3. At least 11 of these tasks should <br />be completed before construction of the STEP pilot plant begins. <br />While DEC believes that all 24 engineering tasks should be completed <br />before initiation of STEP pilot plant construction, it is possible <br />that the last 13 of these tasks could be deferred temporarily. <br /> <br />Rather than <br />together into <br />priority: <br /> <br />list all 24 tasks below, these tasks have been lumped <br />broad categories and these are given below in order of <br /> <br />A. Additional site investigation work to find better STEP sites <br />closer to the saline water source and select one site for design <br />(Tasks 2 and 3) $37,000 <br /> <br />B. Investigate and evaluate potential improvements in STEP process <br />deSign including use of sand and gravel as a growth medium, <br />design philosophy, calciuim sulfate harvesting, spray evaporation <br />system, and the STEP crop production ponds (Tasks 4, 7, 8, 9, and <br />10) $62,000. <br /> <br />C. Additional analysis of Glenwood Springs Saline Water Quality <br />(Task 1) $14,000. <br /> <br />E-ll <br />
