Mid-Continent Resources, Inc. Mines #3 and #4 Portal Reclamation The original slopes at these portal areas cannot be restored since reasonably available soil is not present and even if the fill was available, it could not be restored to a stable slope safety factor . The enclosed maps at a scale of 1 "=100 ' shows the current configuration of the portal areas and the proposed reclamation topographies . Cross-sections are also provided for each mine. As these maps show, a partial reclamation plan using all available f i 11 material is proposed. Al 1 foundation material would be blasted and placed at the bottom of the fill area and would be covered by more than 8 feet thickness of fill . Topsoil could be brought in from nearby borrow areas to provide a thin veneer for revegetation. Furrows could also be placed in the backfilled slopes to help control erosion. Mine #3 The reclaimed topo map for Mine #3 shows a fill volume of 45504 cu .yd. This total may be high depending on the quantity of fill material that is "reasonably available" . Also, the cut quantity will match the fill quantity, so the cut volume of 54202 cu . yd . should be ignored. Approximately 4100 cu.yds of soil will be needed to cover the 7 . 7 acre area to a depth of 4 inches . The reclamation plan proposes a partial backfilling of the highwall to slopes that will be stable and can be revegetated. Mine #4 The reclaimed topo map for Mine #4 shows a fill volume of 35960 cu . yd. This total may be high depending on the quantity of fill material that is "reasonably available" . Also, the cut quantity will match the fill quantity, so the cut volume of 55886 cu . yd. should be ignored. Approximately 4100 cu . yds of soil will be needed to cover the 7 .7 acre area to a depth of 4 inches . The reclamation plan proposes a partial backfilling of the highwall to slopes that will be stable and can be revegetated.
