<br />. <br /> <br />~ <br /> <br />Price-San Rafael Rivers unit on-De artment of <br />Aqriculture) The combined Reclamation; S draft planning <br />report/draft environmental impact statement as distributed to the <br />public in September 1991. The EPA has r sed concerns regarding <br />the loss of wetlands and what they per eive as an insufficient <br />commitment to voluntary replacement of fish and wildlife values <br />foregone. EPA requested additional ime for the submittal of <br />comments. When fully implemented, this will remove 161,000 tons of <br />salt at an estimate cost of $39/ton, nd thus remains one of the <br />most cost-effective in the program and is large enough to make a <br />significant impact on the salt load of the river. <br /> <br />LCco35 <br /> <br />San Juan River (Hammond) Unit (Reclamation-Department of <br />Aqriculture) Reclamation's planning report / environmental <br />assessment is scheduled for completion in September 1992. The <br />project will reduce salt loading by an 27,700 tons per year. <br />Investigations continue by SCS in the San Juan River Basin to <br />determine the feasibility of an onfarm salinity control program. <br />Reclamation has observed saline inflows to the San Juan River in <br />the Hogback area near ~hiprock. Hundreds of oil and gas ----- <br />exploration wells have be~drilled in this area, raising concerns <br />over mobilization of saline aquifers. Reclamation is investigating <br />the apparent salt gains along the San Juan River. <br /> <br />Bureau of Reclamation <br /> <br />. <br /> <br />Paradox Valley Unit (Reclamation) - Repairs and modifications <br />to the injection facilities have been completed. The well annulus <br />monitoring system and the computer control/data collection system <br />have been modified. The system to provide fresh water for diluting <br />the brine during the two year test period has been improved, and <br />the operating orders for the facilities completed. Aquifer and <br />pump testing with different blends of brine and fresh water are <br />being conducted. currently, the injection fluid is about 60 <br />percent brine. To date, no problems with precipitation in the <br />receiving formation have been encountered. <br /> <br />. <br /> <br />Lower Gunnison Basin Unit (Reclamation) - The winter Water <br />portion of the Unit will remove winter flows from canal systems <br />and, in lieu, serve the winter demand from a rural domestic water <br />distribution system. Construction of the winter Water facilities <br />are being done by local entities with funding from Reclamation. <br />Construction is ,ahead of schedule and under budget. Projected <br />completion of these facilities is expected in four years rather <br />than the planned five years. Phase 1 and 3 of the five segments <br />have been completed and segment two is under construction. A <br />status report on ways to reduce the cost of the canal and lateral <br />lining program through construction cooperative agreements, cost <br />sharing, and redesign of the delivery system to reduce canal and <br />lateral lengths is scheduled for completion in 1992. Replacement <br />of laterals with pipe on the authorized portion of the unit is <br />estimated to have a cost of $60 per ton of salt removed. <br />preparation of a preconstruct ion report and environmental <br />assessment will begin in 1992.
