Hole R-1 is within Sub-Area 1 and is considered <br />representative of subsoils in the immediate vicinity. Hole <br />R-1 yielded the following Selenium values at depth: <br />0-2' 1.25 <br />2-7' 1.58 <br />7-12' 0.31 <br />12-17' 2.51 <br />Western Fuels-Utah will remove five <br />and stockpile it as shown on Map 77 <br />ppm <br />ppm <br />ppm <br />ppm <br />feet or less of subsoil <br />From the above analysis related to depth, it is clear that if <br />Western Fuels-Utah removes 12' or less of material, it will <br />have no problem staying below a Selenium value of 2.0 ppm for <br />material to use as non-toxic fill. With an average removal <br />of 1.5' of topsoil and 5.0' of subsoil, Western Fuels-Utah <br />will not be using material high in Selenium as its fill material. <br />Therefore, Western Fuels-Utah will comply with the special <br />stipulation on topsoil protection for Sub-Area 1. <br />
