The 1975 tiscal year's activities in the Upper Coiorado Region were mostly oriented toward initiating environmental studies in preparation for future National Environmentai Policy Act (NEPA) compliance efforts. Biota inventory studies were initiated for environmental statements scheduled in fiscal year 1977 on the Diamond Fork power system, the Jordanelle Reservoir site, and the Provo River, Bonneville Unit, Central Utah Project. Major studies were also initiated with the Utah Division of Wildlife Resources on the Uintah and Upalco Units of the Central Utah Project. In Colorado, environmental studies were completed on Paradox Valley, Dolores Project, and Dallas Creek Project in preparation for environmental statements scheduled for fiscal year 1976. Other studies were initiated on the San Miguel and Animas-La Plata Projects. 6 National Environmental Policy Act Activities The Region entered into a major fishery study agreement with the Forest Service, Fish and Wildlife Service, and the Utah Division of Wildlife Resources for funding a study to be completed by the Utah State University Cooperative Fishery Unit on the effects of varying streamflows on aquatic ecosystems. The objective is to perfect a model developed by the Cooperative Fishery Unit through field testing. This study will take approximately 7 years to complete. A major effort was underway to assess environmental impacts on the Colorado River and Lake Powell because of the operation of Glen Canyon Dam. This effort is the result of the litigation on Glen Canyon, Nakai Ditl'oi vs Morton. Draft environmental statements were filed with the Council on Environmental Quality (CEO) for the Jensen Unit of the Central Utah Project, alternative proposals to China Meadows Dam on the Lyman Project, and the EI Paso and WESCO coal gasification projects, which are located in the Four Corners area. Other major industrial environmental statements were initiated on modifications to the Four Corners generating station and three additional units at the San Juan generating station. Public hearings were held at Window Rock, Ariz., and Farmington, N. Mex., on the EI Paso and WESCO gasification draft environmental statements. The hearings attracted much attention from the residents on the Navajo Indian Reservation. Final environmental statements were filed with CEO on September 5,1974, for the proposed contract for sale of municipal and industrial water from Fontenelle Reservoir, Seedskadee Project, Wyoming, and on January 25, 1975, for the Huntington Canyon generating station and transmission line, Utah (2nd Unit). No new NEPA compliance litigation was initiated in fiscal year 1975. Recording Fishery Data, Upper Provo River.
