It is estimated that Pa~tlox <br />Valley contributes about 200,000 tons of salt per year to the Colorado Rive,r <br />system via the Dolores River. By constructing and utilizing a system of wE!lIs, <br />pumps, pipelines, Injection wells and/or solar evaporation ponds, It is estfrnated <br />that this salt loading can be reduced by 180,000 tons annually. Deep well <br />injection studies are underway to determine if that method of brine dispos.1 is an <br />acceptable altemative to an evaporation pond. <br /> <br />Public Law 93-320, June 24, 1974; and Public Law 98-569, October 30, 1984. <br /> <br />None required. <br /> <br />Definite Plan Aeport approved January 24,1979, and Supplemental scheduled <br />for approval May 1995. <br /> <br />Previous agreements with the Mexican Govemment concemingsallnlty coritrolln <br />the Colorado River and Public Law 93-320 are based upon soCIal and pol~CaI <br />justifications. Furthermore, in 1984, the Congress passed Public Law 98;'569 <br />requiring preference for construction be given to those projects that redilCli <br />salinity at the least cost. The cost effectiveness of this unit .Is measured In t~rmsof <br />cost per ton. The annual equivalent cost of the unit Is $8,023,000; which Inc(udes <br />the total investment annual equivalent cost of $6.353,000 (@ 5.625 percent tor 50 <br />years) plus the annual OM&R of $1,670,000. The annual removal of salt from the <br />Colorado River at Paradox Valley will be 180,000 tons. The annual costpehonof <br />salt removed is $45.00. The cost increase compared to the FY 1993 Budg't <br />Justifications is due to an increase In the estimated Investment. <br /> <br /> <br />The unit is scheduled for completion in 1998. The completion dat. as presented <br />In the FY93 Justifications has been rescheduled from 1996 to 1998 due to th. <br />requirement for further injection testingJollowing the successful testing of <br />Injection Well No.1, current plans call for converting the test faeiliti.s to a <br />permanent injection pumping plant. This conversion would require the instlfllation <br />of dependable and less labor intensive pumps and a supervisory control system. <br />The unit is 65 percent complete as of September 30, 1992. <br /> <br /> <br />193 <br /> <br /> <br />'- , <br /> <br />'-'.c <br />
