within the ten year bond release period without replanting the seedlings. Through TR45, DMG <br /> reduced this density to 500 stems per acre. <br /> • As per Greystone Consultants, a variance application requesting 24 inches of soil cover would be <br /> appropriate given the vegetative and soils data collected to date and with data collected at other <br /> mines in the state which indicate that revegetation success can be achieved with a 24 inch soil <br /> cover. <br /> A copy of Greystone's report is included at the end of this section as Appendix "A". In response to <br /> TR45 application, DMG lowered the cover requirement to 30 inches with a minimum of 12 inches of <br /> topsoil. <br /> V.H Removal, Storage and Redistribution of Topsoil and Subsoil <br /> All areas to be disturbed at any time during the construction, operation, or reclamation of the mine <br /> and its surface facilities will have available topsoil or other suitable growth media separately removed <br /> and segregated from other fill material. Available topsoil was determined from the soil assessment <br /> contained in Section 11.1. Topsoil or other suitable growth media are stockpiled in various locations to <br /> be used during final reclamation. Disturbed areas to be covered with topsoil are indicated on Maps <br /> 43, 44, 45 and 46 ("D" Portal), Map 55 (Water Tank Area), Map 92 (Alluvial Wells), Map 89 <br /> (Ventilation Entry), Map 77 (Refuse Area 1), Map 77A (Refuse Area 5a), Map 150 (Refuse Area <br /> 2/3/4), Map 151 (B Seam ventilation shaft and access), Map 162 (Refuse Area A Site Plan), Map 166 <br /> (RP 2/3/4/5 Combination Soil Stockpile Inventory) and Map 104 (railroad loadout area). Roads which <br /> are to be reclaimed will be covered with topsoil as shown on Map 69 (Haul Road) and Map 55 (Water <br /> Tank Road). In addition, all areas disturbed during the removal of roads, conveyors, or utilities will be <br /> covered with topsoil. A summary of the disturbed areas is shown in Table V-3. <br /> Before the removal of the topsoil, all trees and large brush are cleared and placed in windrows. <br /> Grass, weeds and small brush are not separated from the topsoil. Grass, weeds and small brush <br /> intermixed with the topsoil aid in preventing over compaction and adds organic material to the <br /> stockpiled topsoil. <br /> Topsoil is stripped and transported to the stockpiles by scrapers or front-end loaders and trucks. In <br /> some cases where large amounts of rock fragments are intermixed with the topsoil, it might be <br /> necessary to strip the topsoil with dozers and then transport it to the stockpiles via front-end loaders <br /> and trucks. In order to prevent over compaction during stockpiling, compaction water is not used and <br /> driving over the deposited soil is limited to only that which is necessary to stockpile the material. <br /> During construction, topsoil was stripped to various depths depending on soil type and site specific <br /> conditions, as indicated on Map 28 ("D" Portal Area), Map 52 (Water Storage Area and Access <br /> Road), Maps 70-75 (Refuse Haul Road and Plant Access Road), Map 82. (Refuse Area), Map 90 <br /> (Alluvial Well Area), Map 150 (B-Seam ventilation shaft facility/access road), Map 162 (Refuse Area A <br /> Site Plan) and Map 166. There was no topsoil at the Ventilation Entry Area or associated access <br /> TR-74 (04/2022) V-23 <br />
