Task 3. Reclamation of John Reed Mine <br /> This task consists of the following: <br /> (1) Prior to any disturbance (road-building, excavation, grading, etc.) best management practices <br /> (BMPs) for sediment and erosion control will be put in place downgradient from proposed <br /> activities. These BMPs will consist of placement of silt fence or straw bales in drainages, small <br /> sumps or swales to collect runoff, and any other short-term measure to prevent sedimentation. <br /> (2) Closure of the entryway ("shaft on the hill') on the hillside to the north will be done by use of <br /> several large rocks placed in the opening and then pushed back inside to a depth of 6-8 feet. <br /> Existing onsite rock will then be scattered around and blended into loose rock at the opening to <br /> make it obscure to the casual observer. <br /> (3) Closure of the concrete-lined vertical shaft ("shaft by the road") will consist of capping the <br /> shaft with a pre-fab concrete slab as specified in Appendix 1. <br /> (4) Loading,hauling, and dumping of 4200 cu yds of acid-producing materials from the John Reed <br /> dumps to a repository on the F-Dump, 2.4 miles distant will be required. To upgrade the existing <br /> road from Storke Area to the John Reed Mine, using 6 inches of road rock on the existing base, <br /> assume 250 cu yds of aggregate from the Storke Aggregate Pile will be used. Acid materials will <br /> be marked in the field by wire flags or some other equivalent method. <br /> (5) After complete removal of all acid-producing waste rock materials,the removal areas and road <br /> disturbances will be graded to blend with surrounding topography and clean growth media will be <br /> replaced on the surface to a depth of six inches. It is anticipated that 1600 cu yds will be needed <br /> from the growth media area west of the Colorado Southern RR fill (approx. 1300 ft haul distance). <br /> c <br /> (6) Revegetation will be conducted according to Task 10(1), including mulcing with straw at 1.5 <br /> tons/acre and crimping, for the removal area,the roadway, and around the shafts. <br /> (7) For the wetland area downgradient from the mine, a wetland enhancement procedure (soil <br /> amendments and revegetation) will be used for the 2.1 acre wetland. First, a hole will be dug by <br /> hand to a depth of one foot. The excavated material will be mixed with approximately one pint of <br /> lime (spec: min. 90% CaCO3 and>50% minus 60 mesh) and placed in the hole around the planted <br /> seedling. Spacing for the seedlings (500 bog birch and 700 willows) will be 9 ft x 9 ft. <br />
