A 16 x 38 foot roofed shed addition was added to the south wall of the existing transfer building in October 2003. This addition is supported by five 10-inch x 57-foot pilings driven to a depth of approximately 30 feet. The pilings are constructed with concrete caps supporting concrete piers. This building will be used to cover the rock belt and includes a wash-down water collection sump. A propane heater system was installed on a 20 x 20 x 2 foot concrete pad adjacent to the existing transfer building (northeast side) in October 2003. The heating system is used to heat the transfer building, adjacent sampling building, and to replace the existing heating line to the portal. The heating system utilizes an internal 2-inch polypropylene propane vapor line. The propane vapor feed-line running from the existing 18,000 gallon propane tank on the surface is approximately 700 feet in length. The line is buried at a depth of approximately 4-feet, from the existing propane tank to the new concrete pad location. The line is 2-inch, Schedule 40 steel and is supported and anchored at the point where it goes over the highwall. The system also includes a vaporizer, a 6 x 6 x 6 foot concrete pad at the tank location, and a regulator at the heater location. To protect the 44 bent on the TC stacker conveyor, a steel revetment approximately 25 x 25 x 55 feet was constructed on concrete footers. A roof may be added to the revetment to prevent accumulations of coal inside the revetment. The concrete footers will be pushed to the base of the portal highwall and be buried during final reclamation Employee Coal Loading Area (MR14-274) The proposed Employee Coal Loading Area will be located in the existing unpaved parking area between the Mine Security Gate and the paved Employee Parking Area, as shown on Map 24. Portable pre-cast concrete barriers ("Jersey Barriers") will be used to create a partially enclosed stockpile area, roughly 20' —25' feet square where a stockpile of approximately 30-40 tons of stoker or lump coal would be maintained during the heating season (September through May). The stockpile would be established and maintained using a large mine loader or trucks to transfer coal from the margins of the Run-of-Mine Coal Stockpile and/or Stoker Coal Stockpile. Annual usage from the pile is estimated at approximately 220 tons. Employees could access the Employee Coal Stockpile from the unpaved parking area side of the pile to hand-load coal to their pick-up or trailer. As an existing mine disturbance area, drainage and sediment control are addressed by the existing system of runoff collection ditches and mine sedimentation ponds (Ponds D and F). In addition, to minimize runoff and sediment loss, TC will gravel and maintain access to the pile and an area immediately around the pile. Use of the portable barriers will allow clean-up of coal fines, which may accumulate over time. When no longer needed, reclamation of the Employee Coal Loading Area would involve removal of the portable barriers and recovery and disposal of any remaining coal and coal fines. Explosive Bunker The explosive bunker is shown on Map 24, and encompasses an area of approximately 3 acres. The bunker was constructed in 1975 and has been used since that time by Energy Fuels, and its successors. The site is a leveled, graveled area, with three concrete explosive magazines in place to store blasting caps, delays and other sensitive explosives. Also, tractor-trailers containing explosives were parked in the leveled portion of the explosives bunker area. The leveled area can be used as a storage facility for materials that would not be precluded by safety requirements. Drainage from the explosive bunker area collects in Sedimentation Pond T. This structure has been designed to meet the performance standards of Subchapter K as described in Section 780.25. Sedimentation Ponds TC will be responsible for the maintenance and reclamation of Ponds B, C, D, E, F, G, and T, originally permitted by CYCC(Permit C-81-071,)and the 6-Main North Sedimentation Pond, constructed more recently.
