CRAPTERFIVE [haft EIS Reuislons <br />CHAPTER 1.0 PURPOSE AND NEED • <br />Refer to Table 1-1 (modified) at the end of Chapter 5.0. <br />Pace 1-1 <br />The primary purpose of the proposed Yankee Gulch Project is to produce sodium products at a <br />profit from naturally occurring nahcolite deposits in the Piceance Basin of Colorado. American <br />Soda holds the Yankee Gulch Joint Venture Leases (U.S. Sodium Lease No;~. C-0118328 and <br />C-0118329) for the purpose of developing the sodium resource, ark-American Soda has the right <br />to develop the leases for maximum recovery of sodium so long as this can be accomplished <br />without significant damage to oil shale and in accordance with applicable re ug latory approvals. <br />American Soda has submitted a Commercial Mine Plan to the BLM White ]fiver Resource Area <br />pursuant to 43 CFR 3592 for approval of the Yankee Gulch Project. <br />Page 1-2 <br />Historically, sodium bicabbonate and sodium carbonate have been manufactured synthetically <br />using the Solvay process. This process uses salt, ammonia, carbon dioxide, and Iunestone. The <br />limestone is heated to produce lime and carbon dioxide. The carbon dioxide: is dissolved in the <br />other components, and the result is a sodium bicabbonate precipitate. The s~~dium bicabbonate is <br />heated and dried to form sodium cazbonate (Lewis 1992). The relatively la~•ge energy <br />requirements and the adverse environmental effects of the Solvay process have caused the <br />industry to shift toward processing natural deposits (Lewis 1992). gresessi:~sedit~ • <br />Y-i~ <br />The United States is a world leader in soda ash production due to the natural trona (sodium <br />sesquicazbonate) deposits in the Green River Basin in Wyoming, which provide over 90 percent <br />of the United States' supply and approximately 25 percent of the world's supply of soda ash. <br />Trona ore is removed from several subsurface beds via a method similaz to longwall coal mining. <br />• ~ela~steae}s13 <br /> <br />The international markets for soda ash and sodium bicarbonate are-s~re~El~ ~~erflead <br />g have arown steadily over the last 25 years. Since most of the growth in demand for <br />soda ash is occurring overseas, American Soda anticipates that a lazge portion of its products <br />would be exported to foreign countries, primarily in Asia, but also in Latin America and Europe. <br /> <br />5-2 <br />
