. 3.4.1 Wetlands Addressed in the Henderson Overland Conveyor 404 Individual Permit (Appendix A), wetland mitigation has been chosen as a reclamation alternative for areas that will be converted from wetland to upland in the construction of PC3. The wetland mitigation plan calls for the construction of 2.1 acres of wetland in Area 4 of currently affected land at the Henderson Mill in exchange for 1.54 acres of wetland impact. The wetland mitigation area located in Area 4 exists as a wide section along the Henderson railroad grade south of the proposed location of the PC2 transfer house. The site has adequate hydrologic conditions from source waters in the adjacent West Fork of the Williams Fork. Reclamation methods include the excavation of existing fill using dozer, hoe and shovel equipment, grading to allow catchment and water retention, seeding and planting of wetland vegetation will be conducted using hand methods, as will the application of mulch. Soils buried in the construction of the Henderson railroad • grade will serve as growth media. Wetland disturbances are shown in the Exhibit C. 3.4.2 Upland Forest Reclamation The primary reclamation practice planned for the PC3 Conveyor is revegetation to forest uplands. Because the timber stands described in Exhibit J (Table 1) are generally mature, revegetation will focus on planting to species representative of early successional stages of lodgepole pine forest. Open stands in the project area that allow filtered light to the forest floor demonstrate that diverse herbaceous species and conifer regeneration will provide successional vegetative covers. Grass cover will meet post-mining land use objectives for rangeland. Local dense cover with small forest openings emphasizing woodland edge effects will meet objectives for wildlife habitat. To accomplish these • objectives, final reclamation will include grading to reduce slope gradients for MR 16 January 16.1%8 Plan dm
