<br />OOOJo3 <br /> <br />. <br /> <br />energy development (tar sands) expected in the Price Basin. Preliminary <br />estimates suggest that the salinity concentrations at Imperial Dam could be <br />reduced by 18 mg/L. <br /> <br />Outlook. - Implementation is directly tied to beneficial use for energy <br />development. Utah Power and Light recently reported that proposed Welling- <br />ton Powerplant may be moved out of the basin. Future implementation of <br />this unit is subject to the complex vagaries of energy development and <br />economic conditions over which we have little influence or control. <br />Reclamation anticipates signing an agreement with the State of Utah to <br />evaluate a saline water-coal slurry pipeline to supply coal to IPP as a <br />separate unit or as an initial phase of the Aquatrain project. Letters of <br />intent to cooperate in the study are being prepared to include IPP, the <br />Central Utah Project, Aquatrain, Inc., and the State of Utah as participants. <br /> <br />, <br /> <br />LaVerkin Springs Unit. - Although a concluding report has been completed for <br />the desalting plant and disposal pond alternative, new opportunities are <br />under study. Possible linkup of the unit with a Conservancy District's <br />proposed Quail Creek reservoir may provide mutual benefits. The district <br />has indicated cost-effectiveness of the new plan could be $500,000 to <br />$600,000 per mg/L, assuming clay lining is acceptable. Key issues remain to <br />be resolved: water rights augmentation, pond liner requirements, acceptable <br />leakage, etc. <br /> <br />Outlook. - It may take another 1 to 2 years before the new proposal can be <br />properly assessed. Any future control plan appears to be tied to local <br />beneficial or conjunctive use, while avoiding environmental impacts to <br />the endangered Woundfin minnow. <br /> <br />Lower Virgin River Unit. - Any new control alternative in the area will <br />depend on resolving the problems of ground-water collection and phreatophyte <br />removal for water salvage. <br /> <br />Outlook. - There is potential use of water for powerplant cooling. The <br />State of Nevada generally supports the concept, but the physical problems <br />of collecting sufficient ground water may be difficult. <br /> <br />Lower Gunnison Basin Unit. - The Stage I Regional Director's feasibility <br />report/draft environmental statement was submitted to the Commissioner and <br />sUbsequently filed with EPA on January 4, 1983. Preconstruction activities <br />(advance planning) are scheduled to begin on the winter water portion of the <br />salinity control program in the Uncompahgre Valley in fiscal year 1984. <br />Preconstruction activities are anticipated to be initiated on the balance <br />of the distribution areas in 1986. Salinity reductions at Imperial Dam is <br />expected to be 8 mg/L with the winter water portion of the plan and 6 mg/L <br />reduction with the remaining distribution improvements in the Uncompahgre <br />Valley. <br /> <br />Outlook. - Construction activities in FY 1987 on the winter water portion <br />of Stage I are contingent upon obtaining authorization for construction. <br /> <br />McElmo Creek Unit. - The Regional Director's planning report and draft <br />environmental statement is scheduled for completion in FY 1984.
