The nonnuclear energy technologies to which this assessment is addressed include oil shale and coal gasification developments in the Upper Colorado River Basin. The study is not specifically concerned with other energy conversion processes, although the assessment of water availability for the two specified emerging energy technologies (EETs) is presented against a background of projected conventional energy developments. The objectives of this Upper Colorado River Basin l3(a) assessment are to assess, at a broad regional level of detail: 1. The Hater requirements of coal gasification and oil shale technologies (collectively referred to as EETs) and of the associated growth. 2. The availability of water for the potential development of these EETs and the associated growth. 3. The effects which these potential EET developments and the associated growth would have on the hydrology of the Upper Basin. 4. The effects which these potential EET developments and the associated growth would have on the water quality of the Upper Basin. 5. The estimated monetary cost of providing Hater supplies to these potential EET developments and associated growth. 6. The estimated monetary cost of managing the wastewaters which might be generated by these two EETs. 7. The social, economic, and environmental impacts which would result from the development of water supplies for these potential EET developments and the associated growth (including impacts resulting from reductions in the amount of water available to other water uses, both consumptive and nonconsumptive).
