<br />and pan/}' because It IS compacted, <br />]'IcSparran said. <br />S(>\'era/ uses have been (ound (or <br />the spent shale, bUI economics over- <br />rule them, he said, These include a <br />kind of cement, used as base for roads <br />and as compressed building blocks. <br />Anyone wanting to experiment with <br />the material is welcome to as much <br />as he Wants, McSparran said, <br />A/so questioned by commissioners <br />was the source of water (or a 50,000- <br />barrel.a.day plan!, and subsequent <br />plants. <br />~kSparran said it takes between two <br />and three gallons 0( water (or each <br />gallon of crude oil produced, and that <br />,.this is a totally consumptive use; I <br />none of it would be reco\'ered," He I <br />said existing creeks would not be af- <br />fected, Waler would be taken from the <br />Colorado River. <br />.\/so of concern were land uses and, <br />population growth In the area. <br />)fcSparran said a comprehensive land <br />lIse. environmental impact study is} <br />being planned to weigh the effects of <br />OJ] shale development on the region. ' <br />He estimated a 50.000 barrel plant 1 <br />would require 800-1,000 employes. and I <br />might rcsult in a total influx o( up to I <br />6,0Cl() people into the area.

"Im'ersions or <br />....;nd patterns may Indicatc that we <br />would have 10 put it on top of the <br />mesa to pren'nl problems in Grand <br />Valley." <br />He said no determination on Ihat <br />has been made, all hough an "on-top" <br />location would bt> about 1,000 feetl <br />above lhe mine inslead of 800 feet be-I <br />low it, and possibly some distance <br />away, It would increase the cost of <br />production. . <br />This in itself could be a problem,~ <br />since it is expedeJ that after 20~ <br />years' production from the shale; <br />mine, haulage costs would require re- <br />location of thc shale plant.
