<br />(:l <br /> <br />, , <br />, . <br />Cj <br />..-4 <br />c.) <br />c:- <br /> <br />It is anticipated that data gathered from operation of the <br />demonstrahonliquid CO lcoal slurry test loop and saline .. <br />water cooling tower wili permit AQUATRAIN to progress to Stage 1. <br />Plans for subsequent stages after demonstration are dependent <br />upon findings obtained during testing, and details are subject <br />to 'change' as the project progresses. <br /> <br />Stage I. - The AQUATRAIN Project proposes to design and construct <br />a liquid C02/coal slurry and saline water pipeline to transport <br />5 million tOns of coal and 17,500 acre-feet of saline water <br />per year. This system will be composed of a series of separate <br />lines for the coal slurry and saline water. The liquid C02/coal <br />slurry line will be built to handle future growth to a full <br />capacity of 30 million tons of coal per Year. Design and <br />construction of this first commercially operational stage <br />of the system is scheduled to begin in 1984, with anticipated <br />completion in 1988. Map D illustrates the route of this stage. <br /> <br />The liquid CO Icoal slurry pipeline would transport coal from <br />Emery and Car~on Counties, Utah (near Price) to the Intermountain <br />Power Project (IPP) near Lynndyl, Utah. Potential sources. <br />include s ixlindergraund mines and four CO2 sourCes. The coal <br />would be delivered by truck from mines to a pipeline loading <br />station near Hiawatha JUnction, Utah and,then crushed to suitable <br />size for transport in CO2, At IPP, the coal arid CO2 would <br />be separated, making the coal ready for use in thepowerplant. <br /> <br />It is conceptualized that saline water from the Price-San. <br />Rafael Unit of the Colorado River Water Quality Improvement' <br />Program (CRWQIP)* would be carried by pipeline to UP&L's Hunter <br />Powerp 1 ant fol", use; n coo n n9. A 102-foot-h i ghearthfi 11 <br />dam would be built on Desert Seep Wash,'creahng a 24,000- <br />acre-foot reservoir. ' In addition, a 58-foot-high earthfi 11 <br />damwou1dbe bu'nt at Rock Canyon Creek, forming a 7,000-acre- <br />foot reservoir. Other small drains in ,the area could serve <br />as water sources if needed: Approximately 18,000 acre-feet <br />of saline water with an average salinity level of about 3,800.. <br />mg/L would be carried annually from the reservoirs by pipel ine <br />to the powerp'Tant. 'Vseof this water wtll remove approximately. <br />90,000 tons of salt',from<the Colorado River system, amounting <br />to a reduction of 9mglL TDS (total dissolved solids) at Imperial <br />Dam. (Appendix 2 provides more information on the salinity.. <br />pro~lemand're 1 ated terminology.) <br /> <br />*CRWQIP is the Bureau of Reclamation's overall effort to reduce <br />salt"loading'in the Colorado River by controlling agricultural, <br />point, and diffuse salinity sources. <br /> <br />20 <br />
