2 The enclosed materials addressing the five items above are submitted for review by AFO. The operator is compiling results of sediment pond surveys in conjunction with the approved methodology for determining sedimentation from the site. Pending review of those results, the DMG feels that all of the outstanding issues identified by AFO in its nonconcurrence with DMG's proposed decision to approve the bond release have been adequately addressed. DMG would like to suggest that review of the enclosed materials begin as soon as possible. Results of the sediment pond surveys should be forwarded in approximately two weeks. If you or your staff have any questions about the enclosed materials, please have them contact me. I. Verification that DMG inspected the entire mine site. DMG's October 20, 1992 bond release inspection report includes a statement saying, "Attempts to verify topsoil depths at the Rienau No. 2 Mine on October 20 and 22 were not successful since access to the land was denied." The land owner told the DMG inspector he did not want her to enter his land that day. However, the site was inspected on that day as well as on other occasions by DMG inspectors in relation to the Phase II bond release request. The point of the Phase II inspection was to verify topsoil replacement depths, vegetative cover and erosional conditions. These topics were inspected and reported on, as follows: 1. The DMG conducted a very thorough inspection of the Rienau site on July 13, 1992 at which time vegetative cover transects were sampled by two DMG inspectors. This inspection was conducted after DMG was notified of the operator's intent to request a bond release and in conjunction with vegetation sampling done by the operator. Four 50 meter transects were sampled at one- meter intervals on the Rienau area. A copy of that inspection report is enclosed. 2. During the October 20, 1992 inspection, the DMG inspector inspected the Rienau site from the edge of the reclaimed area. The reclaimed area at the Rienau site is approximately 125 feet wide through most of the area. At its widest point, it is approximately 350 feet wide and on 2h:ly and 3h:ly slopes. The entire area can be visually observed from several locations. Photos taken by the DMG inspector on October 20, 1992 are available. The October 20, 1992 inspection report indicates that the slopes at the Rienau area were inspected and includes a description of the condition of and water levels in the Rienau sediment ponds. The report also references topsoil
