Inspections since the <br />1, April 30 and May 27, 1982. <br />inspection visits of the subject <br />last report have occurred on April <br />All topsoil has been removed prior to placement of the over burden <br />material. The fill in the horseshoe area with the weathered coal and <br />overburden mix has been performed to acceptable methods and all com- <br />paction of this material is excellant. <br />We note that an additional area of coal has been uncovered that was <br />previously not shown as known coal seam areas. This additional ex- <br />cavation will not pose any problem with the reclamation plan except the <br />final contours will not reach the final elevations as shown on the <br />plans. <br />All methods of operations used by the company in the overburden re- <br />placement and in obtaining adequated compaction are acceptable in our <br />opinion. With our inspections, no noted deficiencies were found. <br />Very truly yours, <br />ROBILLARD & ASSOCIATES, INC. <br />~, ~ G~ <br />Orman L.
