.- .,..,) ~'Salinity Upda Recommended Plan Selected at Dirty Devil On February 26, 1985, a planning conference to review the plan formulation working document for the Dirty Devil River Unit was held in Durango, Colorado, with siaff from the Washington Office, Engineering and Research Center, and Upper Colorado Regional Office, The recommended plan for the unit will be the deep-well injection of brine at Hanksville South Salt Wash near Hanksville, Utah, and at Emery South Salt Wash near Emery and Green River, Utah, The Dirty Devil River contributes approximately 155,000 tons of salt annually to the Colomdo River, The recommended plan would reduce the sa~ load of the Colorado River by approximately 20,600 tons per year, The schedule calls for sending the Upper Colorado Regional Director's Final Planning ReporVDraft Environmental Impact Statement (PRIDES) to the Engineering and Research Center and Washington Office in September 1985 and filing the Commissioner's PRIDES with EPA in October 1986, The Commissioner's Planning ReporVFinal Environmental Impact Statement and Record of Decision are scheduled to be sent to the Department of Interior in October 1987, Glenwood-Doterso Springs Unit The Regional Director's Proposed Planning ReporVAdvance Draft Environmental Impact Statement has been released to the Forum (Colorado River Basin Salinity Control Forum) and to appropriate Federal agencies for field level review, Meeker Dome Quarterly monitoring of the observation wells and seep stations continue, The seep stations had declined in flow from the previous readings but the water levels in the observation wells continued to fluctuate with some levels showing a rise and some a decline, '!J If':::, re,~ A Quarterly Report on the ~~f:){), Colorado River Water Quality /fA '1.Jq~Nmprovement Program ~ .pC ,/~" C'Q~~O-9...,^ (9~~- '~/'/l!;!O I.~ '''II/a.

Lower Virgin River A preliminary evaluation has been made using Lower Virgin River water to supply the proposed 2,000 MW Harry Allen Powerplant in southem Nevada Reclamation will be continuing studies to test the viability of collected saline ground water as an alternative water supply source for the plant Price-San Rafael Rivers Unit A meeting to discuss the results of canal seepage investigations was held with the Water Quality Office, E&R Center, and the Regional Office personnel attending, Because of lower seepage estimates, canal lining has been dropped from the recommended plan; the remaining cost- effective feature in the recommended plan is the lining of stock watering pondS to improve winter watering practices. A coordination meeting with the Soil Conservation Service and Reclamation resulted in a decision to look at a new combined altemative involving the possibility of placing some laterals in pipe and combining that with a gravity-driven sprinkler irrigation system, Big Sandy River Unit State of Wyoming representatives met with Reclamation late last year to discuss Reclamation's future work on the Big Sandy River Unit. The State of Wyoming requested that Reclamation study additional use and disposal altematives until April 1965 when another meeting between the two groups will be held, Altematives suggested by the State of Wyoming are being evaluated and costs are being estimated at the appraisal level. SbJdies of saline water use at J 1m Bridger Powerplant are expected to be completed by May with a final report released by July, Lower Gunnison Basin Unit- Uncompahgre Area The recommended plan component that provides for winter livestock water replacement continues to receive wide support from the UVWUA (Uncompahgre Valley Water Users Association), On February 4, 1985, the UVWUA membership voted to direct the Board of Directors to negotiate with Reclamation on the winter water replacement.
