<br />. <br /> <br />THE COAL RESOURCE AND LOCATION OF COAL GASIFICATION <br /> <br />N <br />.- <br />~ <br />.- <br /> <br />In the disaggregation of the U.S. Department of Energy (DOE) <br />projections for coal gasification, a number of factors in the loca- <br />tion of coal gasification plants were taken into account. A nearby <br />supply of coal is only one criterion, though this was the primary basis <br />for the disaggregation of the DOE projections. The environmental impact <br />statements by the U.S. Bureau of Reclamation (1976, 1977) on the proposed <br />Western Gasification Company (WESCQ) and El Paso coal gasification pro- <br />jects indicate a number of varying factors in their choices of locations. <br /> <br />The impetus for coal gasification stems from many practical and <br />political considerations. Chief among these is the increasing shortfall <br />of natural gas supplies nationwide. Political decisions to reduce the <br />United StateS dependence on foreign imports of petroleum and liquid <br />natural gas has led to increased emphasis On coal and the most abundant <br />domestic energy resources (U.S. Bureau of Reclamation, 1976). <br /> <br />. <br /> <br />These decisions have been coupled with reduced discovery of new <br />natural gas supplies. The need for gas supply companies to hold <br />delivery rates at pre-1969 levels, despite increased user demand, has <br />increased the interest of private companies in production of synthetic <br />natural gas (SNG) from coal as a possible alternative source to meet <br />demands. Once private industry became concerned about the need for <br />production of SNG, it began searching for other sources for production <br />of SNG. <br /> <br />The case of '..lESCO, a subsidiary of Utah Construction and lUning <br />Company (UII), is an example. UII had negotiated a coal mining lease <br />for a surface mine on the Navajo Reservation in northwestern New Mexico. <br />Shortly thereafter, a contract was negotiated with the U.S. Department <br />of the Interior to purchase water from the Navajo Reservoir. With both <br />coal and water supplies confirmed, UII entered into a contract with <br />Pacific Lighting [sic] to pursue coal gasification, which "appeared to <br />be the only new domestic source of high Btu gas." (U.S. Bureau of <br />Reclamation, 1976, pp. 1-4). This location has the additional advan- <br />tages of the existing net~ork of natural gas pipelines to service areas <br />throughout the southwest. <br /> <br />In-situ gasification of coal has also been considered and is tech- <br />nologically feasible, though there are many "unkno;ms~' surrounding the <br />full development of in-situ gasification as a totally reliable process. <br />The location of such a gasification operation would depend on optimal <br />supplies of coal and favorable environmental conditions such as minimal <br />potential impacts. Water supply for this process probably does not <br />. restrict the location, since this process uses, in part, available <br />ground water. This method has not apparently been given as wide con- <br />sideration as surface methods, perhaps since most research has been <br />aimed at perfecting the more reliable surface processes first.
