Memo to Erica Crosby <br />Preliminary Certification of Yoast Mine Haul Roads A & B <br />page 2 <br />Based upon the assembled reports I am confident that the compaction of earthen <br />materials was properly accomplished during the construction of both subject <br />Haul Roads at the Yoast Mine. <br />The ass mbled compaction testing reports are covered by a certification report <br />prepared by Michael G. Altavilla, Colorado Registered Professional Engineer No. <br />28455. Mr. Altavilla attests that he was in frequent attendance at the actual <br />construc ion site. Further he attests that the construction occurred in <br />accordan a with the approved plans, and that the roadways are performing <br />properly. <br />I re <br />by <br />the <br />end acceptance of this preliminary certification statement, submitted <br />Coal Company for the preliminary certification of Haul Roads A & B at <br />surface coal mine. <br />cc: Larlrv Routten <br />doc: C <br />P51 \COAL\YOASTRDS.PRE <br />JP/1P <br />
