<br />SUmlARY (Continuec!) <br /> <br />Alternatives <br />-- - -.----- <br /> <br />Reclamation considered one viable alternative and a no action alter- <br />native on the pr0ject modifIcatIons. The vIable alternative passed the <br />four tests--colnpleteness, effectiveness, efficiency, and acceptability-- <br />used to Identify viable plans that woulcl meet the goals of the salinity <br />control progral:1. anel the guidelines of the Department of the Interior and <br />the Bureau of Reclamation. <br /> <br />During the plannIng process a number of alternatIves were developed <br />and studied but were dropped from further consideration by 1984 for the <br />following reasons. <br /> <br />1. Using saline water to transport coal in a slurry pipeline. <br />This alternative does not pass the test of completeness <br />because no potential users could be found. <br /> <br />2. Withdrawing the use of highly saline land. This plan <br />failed the acceptability test because most residents do <br />not want to move or dIsrupt theIr lives ancl are unwilling <br />to sell. The State of Colorado is also opposed to takIng <br />land out of agricultural productIon. <br /> <br />3. Collecting salIne water and usIng It for IndustrIal cool- <br />ing. ThIs alternative failed the test of completeness <br />because no firm commitments were obtained from power com- <br />panies in using this water, although some interest was <br />shown. The plan may be a viable alternatIve In the future <br />If addItional salinity reduction were needed. <br /> <br />4. Collecting and evaporating saline water. The three alter- <br />natIves for evaporating saline flows failed the test of <br />efficiency because their costs per ton of reduction in <br />salinity, discussed below. were beyond what is currently <br />being considered for implementation under the Colorado <br />River Water Quality Improvement Program. They also failed <br />the test of acceptability because the evaporation of sa- <br />line water is not considered a beneficial use in Colorado. <br /> <br />5. Constructing desalting plants. The construction of three <br />different types of desalting plants was investigated, but <br />each failed the test of efficiency because of high costs. <br />The methods included solar, reverse osmosis, and electro- <br />dialysis. <br /> <br />Twelve additional lateral lining segments were studied as part of <br />the irrigation svstem Improvements plan. Tl,ey were not included in the <br />irrigation system improvements plan because their cost effectiveness <br />exceeded what was being considered for implemetltatlon. <br /> <br />S-6 <br />
