1. THE MASS BALANCE FOR OVERBURDEN AND TOPSOIL FOR FINAL REFUSE PILE CONFIGURATION NEEDS TO BE CALCULATED AND IF ANY DEFICIT IS FOUND, EFCI NEEDS TO SUBMIT A PLAN TO MAKE UP THE DIFFERENCE. 2. FINAL DEPOSITION OF THE ON-SITE CONCRETE NEEDS TO BE CLARIFIED IN THE PERMIT. 3. SHOULD EFCI WISH TO PURSUE AN ALTERATION FROM THE PRESENTLY APPROVED POST-MINING CONTOURS AND CONFIGURATION AT THE LOADOUT, THIS ISSUE NEEDS TO BE ADDRESSED IN A TECHNICAL REVISION TO BE REVIEWED AND APPROVED BY THE DIVISION. 4. IN ORDER TO VERIFY FACILITY AND LOADOUT BACKFILL VOLUMES, THE OPERATOR WILL PROVIDE AN ACCURATE CURRENT TOPOGRAPHY MAP WITH APPLICABLE CROSS-SECTIONS TO REVISE MAPS 6 AND 7. THE ABOVE ISSUES ARE TO BE RESOLVED IN A REVISION(S) TO BE SUBMITTED WITHIN 60 DAYS OF PERMIT RENEWAL. V. Sealing of Drilled Holes and Underground Openings Drill holes from 1987 and 1988 exploration projects within the permit area have been filled and sealed, as described in the "Proposed Decision, Phase I Bond Release" Document dated September 15, 1990. Detail of the five portal sealing plans can be found in Sections 4.07.3 and 2.05.4, page 8 R of the permit application. Mine portals will be sealed by constructing a concrete block wall as depicted on Figure 21, seen on page 2.05.4-9. MSHA approved techniques and sealant will be applied on all five portals seals. Once the seals are in place, the entry between the seal and opening will be filled with overburden material in conjunction with subsequent backfilling activities. VZ. Use of Explosives EFCI conducts occasional limited underground blasting activities only. No surface blasting is utilized or planned at the Southfield Mine. Storage and handling of explosives, and any underground blasting that occurs, are conducted under the supervision of a qualified individual in compliance with applicable MSHA and the Department of Alcohol, Tobacco and Firearms requirements. 39
