of the new bathhouse facility. The parking azea was surfaced originally with taz-sand material, but this material has <br />been overlaid with asphalt, and drainage will be conveyed via the existing system, <br />• The original building is of concrete block construction and has dimensions of approximately 200 x 75 feet. <br />Approximate height of the building is 15 feet. The building was placed on a reinforced spread-footer foundation <br />and has a reinforced concrete slab floor. In 2003, under MROl-173, aten-foot expansion to the south was <br />constructed for the bathhouse area only, providing an additional 1,000 squaze feet of locker room for the workforce. <br />The extension design and structure matched the existing building. The extension required construction of piers, <br />footings and walls, and a concrete slab. The extension itself is constructed with wood framing, insulation, and <br />metal exterior sheathing and roof. <br />A mine wazehouse and maintenance shop facility underwent a change in use and now houses a general meeting <br />area and office space for mine personnel. TCC utilizes the former CYCC shop/wazehouse complex to work on <br />equipment and store and dispense materials. TCC also utilizes a shop azea northeast of the Office Building, which <br />was previously used by CYCC as the Preventive Maintenance Bay. Uses of the shop area include construction, <br />maintenance, and storage of materials, equipment, and various supplies. Access to the 2.5-acre shop facility is <br />designated on Map 24, Surface Facilities. <br />The parking azea east of the above-referenced building is being improved to allow better utilization of the azea. <br />The improvements required hauling in approximately 2,500 CY of spoil material to fill in the existing pazking azea <br />and raise it so that runoff drains to both the north and south from this azea. Drainage from this azea is directed into <br />ditches D-2, G-4, and D-6 (a and b). Design information for these ditches is contained in Exhibit 8. <br />A small building has been constructed on the east side of the portal entry. The 10 x 12 x 8 foot building houses the <br />portal slope heating system. <br />2005 Bathhouse Addition (MROS-1951 <br />• An expansion to meet future coal production requnrements for the mine will require approximately 100 new <br />employees. As a result, an addition to the existing bathhouse facility is required. The addition will be constructed <br />on the south side of the existing bathhouse facility, connecting to the existing bathhouse. The addition will be <br />located on a portion of a previously compacted asphalt-coated pazking lot. Existing water and sewer systems will <br />be utilized for the new facility. Roof water will be segregated and rerouted to an existing pump-line at the portal <br />leading to the Area 1 Pit. This water is eventually utilized for underground dust control and at the wash-plant. <br />Existing surface drainage structwes in the area of the addition will remain in place. <br />The perimeter for the addition will be excavated to a depth of four feet for placement of a concrete foundation. The <br />center portion will be excavated to approximately two feet, evaluated for compaction and backfilled. Additional <br />engineered-fill material will be imported to the site, as required. (See construction design or as-builts for greater <br />detail). Foundation work will require construction of piers, footings, walls and a concrete slab. Building <br />construction will consist of an all-metal steel post-and-azch system, with sheet-metal sheathing and internal <br />insulation. The addition will add approximately 2,886 square feet to the existing bathhouse with approximate <br />dimensions of 31 x 98 feet. The design and structure of the addition match the existing building. <br />The topsoil stockpile originally designated for reclamation of the pazking lot and building area (Stockpile SF-3, as <br />shown on Map 29) will be used to cover the new portion of the bathhouse during reclamation as specified on page <br />2.05-101. <br />Warehouse Expansion (MR07-217) <br />In order to accommodate increased material storage requirements associated with mine expansion and the new <br />• Washplant facility, the existing mine Wazehouse facility was expanded to include two additions; a 3,950 square <br />foot (158 x 25 foot) enclosed extension of the current pallet-rack storage area, and the addition of a 1,520 squaze <br />MR07-217 2.05-18 07/16/07 <br />
