Box 774018 <br />Steamboat Springs, Colorado 80477 <br />303-879-6260 <br />January 8, 1990 <br />Re: Overburden Stockpile Inspection and Certification <br />TO WHOM IT MAY CONCERN: <br />In accordance with the Kerr Coal Company Mining and Reclamation Plan, I have <br />inspected the overburden stockpile. The inspection was conducted on Tuesday, <br />October 3l, 1989 and consisted of a visual inspection of the surface of the <br />overburden stockpile and foundations. The stockpile does not show any <br />evidence of cracks, slumps, slides, seeps, springs, or other indication of <br />instability. Therefore, I have concluded that the structure is stable. <br />The stockpile is currently being backfilled in an adjacent pit on the mine <br />property. <br />Sincerely, <br />ACZ INC. <br />.~ <br />Mark S.
