A trQ~smission line would be installed to obtain power from <br /> <br />exist~~G transmission lines approximately 3/4 mile to the west of the test <br /> <br />area. <br /> <br />Only two or three poles would be required for the connectio~. <br /> <br />t2~por~ry sur~ace pipeline ~lould be laid parallel to the west bank of the <br /> <br />r~ver~ co~necti~g the production wells and conveying brine to a point <br /> <br />do,~scre~~ from the area. TI1e Bureau would apply to the Environmental <br /> <br />Protection Agency for a permit to discharge the brine into the stream. If <br /> <br />che permit were not obtained, the brine would be conveyed to an abandoned <br /> <br />evaporation pond, which would be rehabilitated, on the east bank of the <br /> <br />river. <br /> <br />The brine pipeline would be removed following the completion of the <br /> <br />cestlng program. If the data indicated that a 1"ell field would control the <br /> <br />inflol-l of salt to the river, the production wells, piezometer grid, arid <br /> <br />access rOQds would be incorporated into the design of the field. If the <br /> <br />results were negative, the vells would be plugged vith a permanent grout. <br /> <br />3. D?SCR=?TION OF THE ENVIRONMENT <br /> <br />Paradox Valley, a collapsed salt anticline, is about 24 miles long <br /> <br />and frOM 3 to 5 miles vide and is crossed near its midpoint by the Dolores <br /> <br />Piver. The surface materials along the river channel consist of clay <br /> <br />lo~~, loam, sandy loam, loamy sand, and areas of salt deposits. They are <br /> <br />~de,~~i~ by a gypSQ~ cap which covers about 14,000 feet of pure salt and <br /> <br />sal~-rich shale. <br /> <br />. <br /> <br />. <br /> <br />5 <br />
