... 00 en ~ project implementation, The two- day workshops were held at Roosevelt, Utah, for the Uinta Basin Unit and at Grand Junction, Colorado, for the Grand Valley, the Lower Gunnison, and the McElmo Creek units. Participants Included representatives from the ASCS and the ASC County Committees, from the SCS and the local Soli Conservation Districts, from water user grol!Ps, and others, Biology Workshop To strengthen personnel aware- ness and to emphasize the impor- tance of voluntarily preserving, protecting, or replacing fish and wildlife values in the onfarm program, the USDA held a biology workshop at Grand Junction, Colorado, in September. ASCS and SCS personnel from Utah, Wyoming, Nevada, and Colorado participated In the three-day workshop. Legislative require- ments for Including biological con- siderations in the program, as fur- ther described In program rules and regulations and In agency operating procedures, were reviewed in detail. Working in field situations, participants examined salinity control practices that adver- sely impact habitat values and they applied methods for evaluat- ing the magnitude of those im- pacts. Opportunities for identify- ing and installing practices which provide for the voluntary replace- ment of habitat values were iden- tified and demonstrated under field conditions by workshop parti- cipants. BUREAU OF RECLAMATION ACTIVITIES IN 1987 As stated earlier, the status of the units was included in the triennial review and, thus, are not being repeated here; however, a few of the major accomplishments are noted. Paradox Valley Unit, Colorado Drilling operations have been successfully completed to a depth of about 16,000 feet. All coring and casing installations have also been completed, A contract for the brine pipeline which will transport Paradox brine to the injection test well was awarded September 17, 1987, for the amount of $1,600,000. Surface treatment facilities and injection facilities to be used in conjunction with the brine pipelines will be con- structed under separate contract. The special alloy injection string has been ordered with delivery expected about mid-1988, Grand Valley Unit, Colorado The membrane lining of West End Government Highline Canal was half completed by April 6 when water was turned into the canal. The contract for the West End Government Canal, Stage Two, was 87 percent complete at the end of September. Saline Water Use and Disposal Opportunities Unit A memorandum report covers IX (ion-exchange) work done at the Southern California Edison, Etiwanda power generating station 6 . during the fall of 1986 and early spring of 1987, The report con- firms that IX softening of cooling tower make-up feed water, using cooling tower blowdown as the sole regenerant, is practical, Because of early cutoff of testing due to budget considerations. not all objectives were achieved. One of the original objectives was to test the process on the potential feed water for the proposed Harry Allen Power Plant in southern Nevada, Also planned were tests on a vertical tube evaporator to fur- ther concentrate the regenerant brines and tests to evaluate any possible corrosion effects resulting from the IX process. The results of this study provide a major advance in using ion ex- change softening of saline water for use in powerplant cooling, Lower Virgin River Unit, Nevada Recent investigation shows that a total of 48,200 tons of salt could be removed from the river system, with a cost-effectlvenss of about $66 per ton. The 48,200 tons in- cludes 25,700 tons attributed to AWl (advanced water treatment) flows, the proposed Harry Allen Power Plant alternative water supply. Cost-effectiveness of $66 per ton is based on the net reduc- tion of this project of 22,500 tons, Because of proposed budgetary cuts in FY -88, the date for completing the Planning Report/Draft Environmental State- ment is uncertain.
