<br />~ <br />--.1 <br />~. <br />00 impact wildlife habitat. For example, waterfowl and other species dependent <br />upon wetlands and seeps would suffer loss of habitat to the extent that such <br />areas are maintained by conveyance losses, tailwaters, and operational spills. <br />In addition, removal of phreatophytes to reduce incidental losses could <br />adversely impact nesting waterfowl, upland game, small mammals, songbirds, <br />and other nongame animals. Also, drainage ditches and wasteways provide <br />habitat for many fame and nongame species. Thus, reductions in excess <br />diversions and irrigation applications could be expected to reduce or change <br />the value of these areas. <br /> <br />Wastewater Management for Emerging Energy Technologies <br /> <br />Once obtained, the water supplies utilized by EETs will be devoted to <br />process, cooling, and other miscellaneous uses. In the course of being so <br />used, various constituents will be introduced into or concentrated in the <br />waste streams which will result. Thus, the overall water development and <br />management system for EETs must include consideration of how these waste- <br />waters are to be treated or otherwise disposed of. <br /> <br />For the purposes of this assessment, it has been assumed that neither <br />oil shale nor coal gasification facilities will discharge effluents to the <br />surface streams of the Upper Basin. The reasoning behind this assumption <br />is that: (a) the technology exists to reduce the volume of waste streams <br />to the point that they can be disposed of through evaporation, ash disposal, <br />shale compaction, ect.,: and (b) it is to the industries' own financial <br />advantage to so dispose of waste streams rather than treating effluents <br />to achieve the quality which would, under any reasonably forseeable set <br />of effluent guidelines, 1 be required before disbharge to a stream could <br />be made. <br /> <br />Coal Gasification <br /> <br />Coal gasification plants producing pipeline quality gas generate two <br />different major types of wastewater streams that are difficult to treat and/ <br />or dispose of. The first type is relaticely high volume blowdown streams <br />from boiler feedwater treatment and cooling towers, which streams are highly <br />concentrated in salt. The second important wastewater is the stream <br /> <br />1. The U.S. Enyironmental Protection Agency has yet to promulgate <br />effluent guidelines for the coal gasification and oil shale industries. <br /> <br />cx~iii <br />
