<br />~ funds to BLM in a cooperative study, Reclamation will be able to <br />CO determine the effectiveness of these techniques. These studies were <br />CJ initiated in late fiscal year 1990 and will continue with several <br />Ul years of monitoring. <br /> <br />Palo-Verde Irrigation District, California <br /> <br />Reclamation continued monitoring water quality in irrigation <br />district drains. In January, when the canals were out of service, <br />district personnel collected water samples from various drains in <br />the district. Reclamation performed a constituent analysis at its <br />Boulder City, Nevada, laboratory. The downward trend in salinity <br />concentrations of the outfall drain is continuing. <br /> <br />Price-San Rafael Rivers Unit, Utah <br /> <br />The combined Reclamation/SCS draft PR/EIS was printed in August and <br />distributed to the public in September 1991. At $39 per ton for <br />161,000 tons of salt controlled, this unit remains one of the most <br />cost-effective in the program and is large enough to make a <br />significant impact on the salt load of the river.. Work is underway <br />in 1992 to resolve wetland replacement issues raised during the <br />review of the draft EIS. <br /> <br />San Juan River Unit, New Mexico (Hammond Area) <br /> <br />Planning continued on this subunit in fiscal year 1992. A PR/EA is <br />scheduled for completion in December 1992. This unit remains one of <br />the most cost effective in the program. Total project impact is <br />estimated at 27,700 tons per year. <br /> <br />San Juan River Unit, New Mexico (Hogback Area) <br /> <br />Reclamation has received reports and observed saline inflows to the <br />San Juan River in the Hogback area. Hundreds of oil and gas <br />exploration wells have been drilled in this area, raising concerns <br />over mobilization of saline aquifers. One wash has been observed to <br />be discharging saline water with very unusual chemistry. <br />Reclamation will investigate the apparent salt gains along the <br />San Juan River. <br /> <br />Uinta Basin Unit, Utah <br /> <br />This unit has been proposed for construction by Reclamation and was <br />sent to DOl for review. DOl has requested Office of Management and <br />Budget comment on the budgetary impacts of the unit. <br /> <br />16 <br />
