4 David Berry and Joseph J. Dudash of the Division of Minerals and Geology attended the bond release inspection. The Office of Surface Mining did not send a representative to this inspection. The Division's inspection report dated October 9, 1996 details the results of the Phase One Bond Release Inspection for the west side of the mine site. Several adequacy issues were raised in that inspection report. Some of the adequacy questions involved work in the field. Other adequacy questions were concerned with the submittal of additional information. The operator responded to those adequacy questions with additional field work and a submittal dated April 8, 1997, and received at the Division on April 10, 1997. The additional field work was inspected and approved by Division personnel and documented in inspection reports dated November 6, 1996, May 22, 1997 and June 3, 1997. The additional submittal of information was reviewed in the Division office in May of 1997, and approved. II. CRITERIA AND SCHEDULE FOR BOND RELEASE PHASE I Rule 3.03.1(2)(a) states, "Up to sixty percent of the applicable bond amount shall be released when the permittee successfully completes backfilling, regrading, and drainage control in accordance with the approved reclamation plan." With regard to partial Phase One bond release, the approved reclamation plan for the Hayden Gulch Mine calls for the dismantling and removal of the structures associated with mining activities, removal of topsoil stockpiles, backfilling and grading of the facilities area and former topsoil stockpile areas, and the reestablishment of the drainage system. III. OBSERVATIONS AND FINDINGS PHASE I The mine related structures were removed in the late summer of 1987. These structures included the shop/warehouse building, office building, bathhouse, sewage disposal system, the fuel storage facility, the explosive storage facility, power poles and equipment wash facility. The concrete pads beneath the office and shop buildings were fractured and buried in place, under five feet of fill, before topsoiling. The only mine related structure remaining in the field is the telephone junction box, located just northwest of pond 3. The operator reported that the telephone company has been notified of the need to remove this junction box. Topsoil stockpiles A and B were depleted in the fall of 1987. The two areas were regraded during this same time. what remains of the area designated as topsoil stockpile C appears to be a topsoil layer placed
