Approval of this change will allow Henderson to move forward with our haul road construction and topsoil salvage project this summer. Engineering for the new hau] roads and aggregate mining has been completed and we hope to bid the project on May 28, 2003. This project will provide infrastructure (haul roads) to facilitate Henderson's topsoil salvage efforts in the future as well as to begin moving topsoil resources to their ultimate storage locations. Henderson is requesting approval to relocate Henderson's south topsoil stockpile location (Area 21 per the approved reclamation plan). This original location, on the north hillside of Fridge Ridge or the south end of No. 2 Dam, is not suitable for long-term topsoil storage due to its topography and the large drainage that is present to the west. The proposed new location for long-term storage of topsoil meets the conditions set forth in the Division's Minerals Program Rules and Regulations, Rule 3.1.9, Topsoiling. Please see the attached map (Topsoil Stockpile Plan -South Stockpiles) providing the exact location(s) of the proposed area(s) and their acreage and soil storage capacities. The larger area is the location we plan to utilize in 2003. The second, smaller location was identified as another good location for soil storage. Henderson does not anticipate using the smaller location, however, because the proposed new location is substantially smaller than the previously approved area, Henderson would like to maintain the flexibility to utilize this location if necessary in the future. Both locations are free from any contamination or acid- forming material and protected from wind and water erosion [Rule 3.1.9 (1)]. Both locations have recently been logged and all woody vegetation present has either been removed (saleable lumber & firewood), will be burned, or will be appropriately incorporated into the relocated soil [Rule 3.1.9 (2)]. Both areas are located above the ultimate tailing deposition elevation and will not interfere with future projects such as decant line extensions and/or a barge pump-back system. Stockpiles will be revegetated each fall after a soil salvage project has occurred and will be not disturbed until final reclamation [Rule 3.1.9 (3-4)]. In addition, as shown on the drawings, underdrains will be
