• 2.04.6(2)(b) <br />In summary the analysis of the overburden/inter- <br />burden for drill holes CC-1-90 and CC-3-90 and the drill hole in <br />the east half of section 33 did not identify any physical or <br />chemical properties which would pose a serious problem to <br />revegetation or water quality. The mining process will very likely <br />mix the overburden adequately to mitigate any potential problems <br />with pH and acid potential in the subsoil. The overburden handling <br />plan in Section 2.05.3(6) further addresses this issue. <br />The detailed geochemical laboratory analysis reports <br />are enclosed as Exhibit 6. <br />COAL SEAM ANALYSES <br />The following coal quality information is derived from a <br />limited number of samples. Only a wide range in values is given <br />because of the limited data. <br />Short Proximate Analyses - As Received Basis <br />Range <br />BTU 8,000 - 12,000 <br />Moisture 68 - 158 <br />• Ash 108 - 208 <br />Sulfur 0.308 - 0.758 <br />• <br />2.04-11 July 1992 <br />
