C';) ,..... c",; ....; c.. ., of interest received by Aquatrain, Inc., from potential participants. The proposed route follow, for the most part, existing corridors (e.g., highways and existing pipelines), thus reducing certain environmental impacts. Industry and public comments are now being sought to evaluate preliminary alternatives. Detailed environmental analyses along the proposed corridor routes will be done in the preconstruction planning stage, and corridor selection will be made after National Environmental Policy Act requirements have been satisfied. Sources and Markets' Conceptually, the pipeline would originate in Wyoming where saline water, coal deposits, CO2, and other commodities are readily available. Major depos,ts of trona, an ore from which soda ash is made, are also available for mining, processing, and export by AQUATRAIN from southwestern, Wyoming. As the pipeline travels through Colorado and Utah, it would collect more saline water and coal as shown in Maps Band C. Powerplants and industries along the way could take coal and saline water from the pipeline system for various uses. Along the corridor routes, there are potential powerplant uses for nearly 200,000 acre-feet of saline water (Figure 2) as well as domestic markets for 30 million tons of coal per year. At a port facility on the Pacific Coast, coal could be exported to foreign markets. When the CO and coal have been separated, the CO2 could be marketed fo~ use in enhanced oil recovery, welding, beverages, refrigeration, and chemicals--or be returned for reuse in the pipeline. Project Description As now envisioned, implementation of the AQUATRAIN Project wi 11 begin with a 14-mile demonstration unit followed by three distinct stages of pipeline system construction. Each stage would be initiated based on investments and market demands, .and subsequent stages may be added as needed. Demonstration Unit. - The demonstration unit will include a test loop and a cooling tower using saline water. Work is expected to begin on construction of a 14-mile demonstration test loop in 1984, with completion in 1985. The underground pipeline loop (Figure 3) will be located at a powerplant in the western United States and will be designed to transport coal at a rate of 5 million tons per year in a liquid CO2 slurry. Preliminary discussions have been held with Uta" Power and Light Company regarding locating the test loop at their Hunter Powerplant near Castle Dale, Utah. The demonstration loop, using commercial-size equipment, is needed to fully verify (1) the liquid CO2/coal slurry technology 13
