<br />Following consultation with the Forum, Reclamation is <br /> <br />defering further <br /> <br />investigation <br /> <br />of the GlenwoodDotsero <br /> <br />Springs Unit. A concluding report was issued in February <br /> <br />N <br />U1 <br />w <br />(0 <br /> <br />1986. <br /> <br />Under the Saline Water Use and Disposal Opportunities <br />Unit, installation of a test loop for the use of saline water <br />for power plant cooling has been completed at the Southern <br /> <br />California Edison Company's Etiwanda power plant near <br /> <br />Ontario, California. The selected hardware will be evaluated <br /> <br />under actual field conditions to verify technical performance <br /> <br />and operation of the use of saline water for cooling. A <br /> <br />parallel study of the economics of the test loop and selected <br />hardware is also in progress. The letter of agreement for <br /> <br />cost-sharing the hardware study has been extended to December <br /> <br />1986. <br /> <br />An earlier contract study of the use of saline water for <br />cooling in the Jim Bridger Power Plant found that by using <br /> <br />side-stream softeners and disposal ponds, about 8,000 acre- <br /> <br />feet per year of Big Sandy River water could be used with <br />total in-plant costs of about $70 per ton of salt removed. <br />However, when the costs of construction of the well field for <br />the collection of saline water and the pipeline were <br />included, the total estimated cost-effectiveness for using <br />saline Big Sandy River flows in the powerplant ranged from <br />$146 to $152 per ton of salt removed. These costs are not <br />competitive with other salinity control units at this time. <br /> <br />-12- <br />
