<br />l'V <br />t.U <br />l\;, <br />~ opportunities relative to the conditions which would prevail were such <br />improvements not undertaken. <br /> <br />This is not to say, however', that there would be no significant <br />environmental impacts. To the contrary, implementation of more efficient <br />irrigation water management methods could significantly impact wildlife <br />habitat. For example, waterfowl and other species dependent upon wetlands <br />and seeps would suffer loss of habitat to the extent that such areas are <br />maintained by conveyance losses, tailwaters, and operational spills. In <br />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 game and nongame species. Reductions in excess diversions <br />and irrigation applications could be expected to reduce or change the <br />value of these areas. <br /> <br />Wastewater ManaRement for EmerRinR EnerRy,Technologies <br /> <br />Once obtained, water supplies utilized by EETs would be devoted to <br />processing, cooling, and miscellaneous uses. In the course of being so <br />used, various constituents would be introduced to or concentrated in the <br />waste streams that would result. The overall water development and manage- <br />ment system for EETs must include consideration of how to treat or other- <br />wise dispose of these wastewaters. <br /> <br />It has been assumed in this assessment, that neither oil shale nor <br />coal gasification facilities will discharge effluents to the surface <br />streams of the Upper Basin. The reasoning behind this assumption is <br />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 dis- <br />posal, shale compaction, etc.; and (b) it is to the industries' own <br />financial advantage to dispose of waste streams rather than treat efflu- <br />ents to achieve the quality that would be required before discharge to <br />a stream could be made under any reasonably forseeable set of effluent <br />guidelines. 1 <br /> <br />Coal Gasification. Coal gasification plants producing pipeline <br />quality gas generate two different major types of wastewater streams <br />that are difficult to treat and/or dispose of. The first type is <br />relatively high-volume blowdown streams from boiler feedwater treatment <br />and cooling towers. These streams are highly concentrated in salt. The <br />second major stream is the wastewater condensed out of the product fuel <br /> <br />1. The U.S. Environmental Protection Agency has yet to promulgate effluent <br />guidelines for the coal ~aslfication and oil shale industries. <br /> <br />1-16 <br />
