<br /> <br /> <br /> <br /> 11 <br /> J. Stream Buffer Zones <br /> <br />No changes to the stream buffer zones were proposed in the PR-2 application. <br /> <br /> K. Probable Hydrologic Consequences <br /> <br />The most current analysis of the probable hydrological consequence was done for <br />the NHN Mine in the issuance findings document dated May 4, 2012. <br /> <br />PR-2 is proposing to revise the postmining land use configuration, and update the <br />topsoil handling plan, the revegetation plan and irrigation designs. All the <br />proposed changes will occur within the sediment control boundary. Vegetation <br />will be established on these areas to support the postmining land use and provide <br />sediment control. A sediment control demonstration will be completed before the <br />sediment control structures are removed and final bond release approved. <br /> <br />IV. Topsoil <br /> <br />Topsoil salvage and replacement is described in Section 2.05.4(2)(d) of the permit. <br />Map 2 .05 .4(2)(d)-1 shows the proposed replacement thicknesses for topsoil. <br /> <br />The Division proposes to approve the revised reclaimed topsoil locations and depths. <br />The center 88.2 acres of the Garvey property will have 1.0 feet of Progresso topsoil on <br />top of 0.8 feet of mixed topsoil. This configuration will accommodate a center pivot <br />irrigation system to establish the irrigated pasture/cropland area. The perimeter of the <br />Garvey property will have 1.2 feet of mixed topsoil that will be used to establish the <br />dryland pasture areas. These changes were requested by the landowner in a letter dated <br />August 9, 2017. The letter is in Appendix 2.05.5-1 of the permit. <br /> <br />V. Sealing of Drilled Holes and Underground Openings <br /> <br />The Division will require that each hole, well or other underground opening be capped, <br />sealed, backfilled, or otherwise properly managed (4.07.3). <br /> <br />VI. Use of Explosives <br /> <br />No changes to use of explosives were proposed in the PR-2 application. <br /> <br />VII. Disposal of Excess Spoil <br /> <br />No changes to the disposal of excess spoil were proposed in the PR-2 application. <br /> <br />VIII. Coal Mine Waste Banks <br /> <br />No Coal Mine Waste Banks have been proposed for the New Horizon North Mine.
