A 2: ill slope would <br />require approximately 17,000 Yd Assuming an average <br />overburden depth of 6 feet throughout the site is <br />available, 2.6 acres and 1.7 acres of overburden, <br />respectively, would be needed to obtain the quantities <br />above. <br />If you have any questions, please call me. <br />Very truly yours, <br />Bruce A. Honisch, P.E. <br />BAH/mah <br />
