horizontally from the portal, and almost 300 vertical feet below the portal. No <br />future workings are planned to extend significantly to the north, which is the up <br />dip direction. The water in the mine will establish a natural hydrostatic <br />equilibrium between the water in the mine and the water trying to flow into the <br />mine. Since the predicted worst case high point of water in the workings will still <br />be over 220 feet vertically lower than the portal, it is not possible that water in the <br />mine could get to the portal after reclamation. The mine portal will be sealed with <br />50 feet length of fill placed in the entry, or until competent rock is encountered. <br />B. Mine Yard <br />To relieve compaction from vehicle traffic, the mine yard will be ripped to a <br />depth of 12 inches. If limited by rock, the ripping could be less. It will then be <br />seeded. <br />C. Mining Buildings /Trailers <br />Reclamation will include the removal of all buildings and other structures. <br />Concrete foundations will be broken up and placed in the portal prior to <br />backfilling the portal. The soil will then be ripped and seeded. <br />The following structures will be removed: <br />Lower Mine Area <br />• Dry change facility, shop, and office building, 70 ft x 40 ft size, one story <br />(Building must be dismantled.) <br />• Electrical power substation, 45 ft x 16 ft (Owned and operated by San <br />Miguel Power. Removal is the responsibility of San Miguel Power.) <br />• One 500- gallon diesel fuel tank on the JD -9 pad area west of the portal. <br />• Propane tank near office <br />Upper Mine Area <br />• Treatment houses <br />• Emergency hoist <br />D. Haulage Ramps and Roads <br />The access road to JD -9 will remain in -place after reclamation to facilitate site <br />access. The side slopes of the road will be seeded and mulched immediately after <br />road installation using the same seeding plan as the rest of the portal area. This <br />will facilitate future access to the site for DOE. <br />The haulage ramps accessing the ore and waste stockpiles as well as any roads <br />built for access to the ventilation shafts, will be ripped, soil will be distributed <br />where needed based on availability, and the areas will be pocked and seeded. <br />E -3 <br />
