construction will consist of an all -metal steel post- and -arch system, with sheet -metal sheathing and internal insulation. The addition will add approximately 2,886 square feet to the existing bathhouse with approximate • dimensions of 31 x 98 feet. The design and structure of the addition match the existing building. The topsoil stockpile originally designated for reclamation of the parking lot and building area (Stockpile SF -3, as shown on Map 29) will be used to cover the new portion of the bathhouse during reclamation as specified on page 2.05 -101. Warehouse Expansion (MR07 -217) In order to accommodate increased material storage requirements associated with mine expansion and the new Washplant facility, the existing mine Warehouse facility was expanded to include two additions; a 3,950 square foot (158 x 25 foot) enclosed extension of the current pallet -rack storage area, and the addition of a 1,520 square foot (95 x 16 foot) covered shed storage area. Both additions connect to the existing Warehouse structure as shown on Figure EX49H -Fl. The Warehouse expansion areas are contained within the existing disturbed area "envelope" defined by the outer edges of the current Warehouse facility, and resulted in no new surface disturbance. Construction involved limited excavation for the floor slab for the enclosed extension; shallow drilling (approximately 20 feet) for 18 -inch concrete support piers for both the enclosed extension and the covered shed storage; forming and pouring the piers and floor slab; erection of the pre- fabricated support frames for both extensions; and placement and connection of the metal sheathing walls and roof. Materials Storage Areas A number of areas located around the site are utilized for equipment/materials storage and handling. Primary areas include the warehouse and welding shop yards and pads, an area south of the shop, the large storage pad north of the bathhouse, the area around the PM Bay north of the Mine Entrance Road, the southern portion of the stoker coal • loadout area, the dry storage area near the portal, an area south of the Raw Coal Stockpile, the Washplant yard and pad areas, the Batch -Weigh Loadout yard, and the large storage yard in the Explosives Storage area. Additional areas include equipment storage pads west of the Warehouse, beltline storage area along Haulroad A, temporary storage near Pond B, an area along the ranch road to the east of the fire- training area, and the area across from the Batch -Weigh Loadout in the area' of the old Lube Facility site. Additionally, there are equipment staging and handling areas along the PM Bay access road and south of the refuse pile area, for equipment assembly and preparation, primarily in association with longwall moves. Locations of these areas are shown on Map 24, Surface Facilities and Freshwater System. The materials storage areas associated with the stoker coal loadout area, at the PM Bay, at the base of the portal ramp, near the light -duty bay, and across from the shop are also permitted for handling and storage of non -coal, wastes per Rule 4.11.4(1). There are five primary garbage or solid -waste handling areas; near the portal, in front of and behind the warehouse /shop area, at the Washplant, and near the PM Bay. Other small satellite areas such as the Batch -Weigh Loadout and Operations Center are served by smaller dumpsters, which are periodically emptied. Storage Area North of Weld Shop In order to accommodate additional supplies needed for the longwall, the storage area around the weld shop was expanded. The storage area, approximately 0.5 acres, is shown on Map 24, Surface Facilities and Fresh Water Systems, with the additional disturbance also depicted on Map 29, Reclamation Map. The expansion will be upslope of the existing collection ditch in an area that has been previously reclaimed. The topsoil, approximately one foot in depth, will be salvaged and windrowed below the storage area. The windrowed topsoil will be seeded with the topsoil stockpile stabilization seed mixture. At the time of final reclamation, the topsoil will be redistributed over the site. • In order to facilitate material storage around the weld shop area, three concrete pads, approximately 20 x 60 x 1 foot will be constructed to the east of the shop. Pipe and other hard goods will be stored on these pads. In addition, a 100 x 15 x 1 foot concrete apron will be constructed on the south side of the building to increase the utility of that MR09 -238 2.05 -18.1 06/26/09
