The identification of unsuitable material would <br />,' best be accomplished by sampling discrete strata in the undisturbed <br />overburden to identify materials for special handling. An additional <br />approach would be to sample the spoils prior to topsoil replacement. <br />It does not appear that the approved sampling is an effective solution <br />to the problem. <br />In order to complete the record of analysis upon which a finding of compliance <br />must be based, could you provide your rationale or explanation of how you <br />reached your conclusion on the above points. <br />If you have any questions regarding this matter, please contact Walter Swain <br />of my staff at (303) 837-5656. <br />Sincerely, <br />Allen D. ein <br />Administrator <br />Western Technical Center <br />Enclosure <br />
