Show conditions. Temporary turbid conditions could be caused, however, where short reaches are located immediately adjacent to the stream. The 40- acre State game farm site in Harmston Reservoir basin would be inundated. This farm now provides food and shelter for upland game and mitigation would likely be made. About 97 miles of tunnels with lined diameters ranging from 7.75 feet to 12 feet would aggregate waste material of 2,470,000 cubic yards. This would be assuming a 40- percent expansion of the solid rock to be excavated. The amount of material would cover an estimated 2 acres of land at an average depth of 30 feet. The 22.2- mile- long Flaming Gorge Tunnel No. 1 and the 16.9- mile- long Jordanelle Tunnel would create the most severe waste disposal problems. With greater quantities of waste material than usual in the Jordanelle Tunnel and with a confined canyon ( Big Cottonwood Canyon) a huge waste pile would be accumulated. Fines picked up by precipitation on the slopes of the dump would be carried into Big Cottonwood Treatment Plant located about 2 miles below the outlet portal„ Tunnel wastes from the Flaming Gorge Tunnel No. 1 near the inlet end would be placed under water in Flaming Gorge Reservoir. At the outlet end the wastes would be spread on the flood plain of Steinaker Draw. Since Steinaker Draw contains an intermittent stream, fines from the waste pile would be occasionally carried into the draw and into Steinaker Reservoir. Oil drilling activities in the Uinta Basin are expanding rapidly. To date, only one rig is located within or close to a reservoir basin. This is at the proposed Altonah Reservoir. Wells within the reservoir's normal water surface area would require special treatment in order to continue oil recovery. Esthetics would be altered throughout the Unit area. However, there would be no virgin areas involved where unique vegetation zones would be affected. Transmission lines to pumping plants in the Uinta Basin totaling 89 miles would cause disturbance of 350 acres. This would mostly be due to construction of temporary roads along the alinements required for stringing wire. Scars from these roads would remain visible for many years. Some would be permanent. 435 |
