SalinityUp:date --- - - -. October 1988 -. . - - -- -- - -. l\) Ul 0) i-'- Paradox Valley work resumes in Colorado Construction resumes on the in- ~tanation of the injection tube for the Paradox Vaney Unit deep in- jection test wen, The injection test wen was completed to a total depth of about 16,000 feet. It was closed and capped and the drill rig dismantled, The Environmental Protection Agency (EP A) continues to monitor the EPA-issued Under- ground Injection Control (VIC) permit and has determined that the as-built well is adequate to meet the design criteria. - The 5-1/2 inch special high nickel alloy injection string was ordered and produced in Hereford, England, and in Huntington, West Virginia. The tubing string was threaded in Alabama and is currently awaiting delivery as needed. The inl'ection wen No.1 should be comp ete by late 1988. Construction of the 4-mile brine pipeline was completed in September 1988, The brine pipeline will transport the brine from the prod uction well field to the disposal well. The surface treatment building is complete and the wellhead injection build- ing construction is underway, This injection building will house three 1600 horsepower high pressure pumps. Following completion of the injection wen the surface facilities will need to be completed, hooked 8273.100.40 ll;$ ;l;)e~trij~ntoft~e'II.r~htil' 'lll'eanof.R~lamatio!t ......... ., .~. 2uarterly'Re~ort ol{tbe .

In the foreground is the spill prevention pond. The relief line which penetrates the flexible membrane pond liner is visible. The brine injection pumps will be used to pump the Paradox Valley brine into Injection Test Well No.1 at an anticipated rate of 650 gallons pei minute. Normal operation will utilize two pumps with the third as a backup. up to the well and tested. Deep wen injection is expected to start around mid-summer of 1989. A contract was initiated with the Department of Energy and the U,S, Geological Survey to analyze the injection brine and resident for- mation brine in the well to deter- mine if the brines are compatible for injection. Initial determination appears to be satisfactory, EP A is currently reviewing proposed changes in the monitor- ing systems. In addition, EP A will review injection wne comple- tion data, and monitor initial com- patibility studies and test results to assure that the well functions as planned, Lower Gunnison Basin Preconstruction funds for FY 1989 have been approved for the winter water portion of the Lower Gunnison Basin Unit. Monies in the amount of $250,000 would be .obligated to the Uncompahgre Valley Water Users Association to collect design data on their system in preparation for construction,
