final hiahwall to exist at the new scraper area would tie equivzlent to • <br />approximately 11,000 cubic yards of highwall reduction or• two percent of <br />one spoil ridge. Rlso, upon examination of the four spoil ridges and the <br />Wadge left open pit reduction calculations in the bond calculations, it <br />can be seen that the left open pit was included in both calculations when <br />it was only necessary to include it in the double highr+all calculations. <br />The conservativeness of the band estimate can cover the new scraper area <br />and no additional bond need be obtained. <br />• <br />• <br />4 02/13/87 <br />
