original contour. This would require demolition of the foundation pillars, excavation of sufficient material from the outslope to backfill the cut bank, construction of drainage control structures across the backfill and excavation areas, and revegetation of all disturbances. The proposed reclamation concept is to remove the concrete pillars and end wall foundations. This activity will destroy the majority of the vegetation currently growing on the corridor. It is suggested that a limited amount of dirt work be accomplished in order to approximate the original topography and to encourage establishment of pre-mining drainage patterns. This dirt work would entail grading material from the outside edge of the corridor and from the raised center section of the corridor toward the cut slope. This material and the corridor remnant will be sloped to the south upon completion of grading activities at about a five percent grade. Water bars and drainage trenches should be constructed periodically as needed for the purpose of transporting uphill flow across the corridor to the outslope. At least three of the constructed drainages will transport a sufficient volume of water indicating that ripraping these drainages would be necessary. The entire corridor will be ripped perpendicular to the slope to a depth of eighteen inches on thirty inch centers, fertilized, seeded and mulched. An alternative is to remove the foundations, place fill material against the cut slope in areas which exhibit a steep or tall cut for the purpose of enhancing slope stability, create drainage swales to promote pre-mining watershed conditions, rip and revegetate the entire corridor length as per above. Although this is a less costly approach, it tends to negate the permit requirement of achieving approximate original contour for this area. In 1995 and 1996, Resources has indicated by memo that, as part of the 405 acre development plan, they want the corridor to be utilized as a trail. Specific reclamation guidelines were not provided. Although either reclamation approach would suit this use, the second alternative may be more amenable to this use, as a slope to the outside would not be created. B and M Stockpiles Reclamation of the B (upper) stockpile was defined in the permit as part of a revision that permitted the construction of the Rock Tunnel and the overland conveyor. The revision file contains correspondence that suggests that this area would be returned to approximate original contour. No construction specification has been provided in the permit, nor has the source of the material to be used as fill for the B stockpile been identified. The B stockpile is located on a south facing hillside immediately 3
