• Runoff from the loadout and stockpile area will be routed to a small sedimentation pond at the <br />northeast corner of the area. Runoff from the surrounding area will be diverted in a ditch on the <br />south side of the loadout for discharge east into Lorencito Canyon. <br />Sediment control reservoirs will be constructed prior to disturbance of the overlying watershed, <br />and will be retained through the achievement of the Phase II bond release. Ditches will be <br />reclaimed when they are no longer needed to divert water. Some ponds will be proposed for <br />permanent retention on the condition they meet the requirements of Rule 4.05.9(1) following <br />reclamation. <br />(5) Topsoil <br />Topsoil and usable subsoil (A and B horizons) will be removed using tracked dozers. Topsoil and <br />subsoil will be removed from areas to be affected by the surface mines following removal of <br />vegetative cover but prior to any other surface disturbance such as drilling, blasting, or <br />overburden stripping. Salvage areas for the surface mine are shown on Map 2.05.3-3e. <br />LCC will remove topsoil prior to operational disturbances except when slope angles restrict these <br />activities. Additionally, areas with negligible amounts of topsoil will not receive topsoil removal. <br />• LCC proposes several approaches for the removal of shrubby vegetation from the head-of-hollow <br />fill areas, and for its subsequent use. Shrub removal in the fill areas will be achieved with <br />clearing or burning. Presently, LCC proposes to accomplish vegetation clearing by chaining or <br />dozing activities. Rotoclearing may be a possibility, however, implementation of this method <br />depends both upon the acquisition of a Madge Rotoclear, and upon its feasibility in rocky and/or <br />steep areas. Burning is retained as an option for vegetation removal due to its function on slopes <br />which are too steep for other management practices. <br />Upon removal, LCC proposes to use the resulting organic material in sediment control practices <br />as well as an organic mulch. Sediment control practices will include the establishment of brush <br />check dams and brush windrows to reduce slope lengths. This additionally will provide shelter <br />areas for wildlife such as small rodents. Alternatively, organic material removed from the surface <br />mine may also be chipped and used as a surface mulch. <br />Volumes of available soil have been calculated using the average thickness of salvageable soil for <br />each soil type as noted in section 2.04.9. As shown in Table 2.05.3-2, a total of more than 1.5 <br />million cubic yards of topsoil and subsoil have been identified for removal from the surface mines, <br />roads, loadout facility, and ponds. Soils will be salvaged for slopes up to 50 percent as identified <br />on Map 2.05.3-3e. The proposed amount to be removed and stockpiled excludes one soil type <br />(Louviers-Rombo-Travessilla Complex) due to its elevated rock content. Furthermore, additional <br />soil may be opportunistically salvaged as possible. <br />r <br />a'rR-o~{ <br />LorcncitoPmt-PMT(475)JWy2001.wpd 2.05-33a (Revised 10/24/01) <br />
