dug so a soil profile could be obtained. After the backhoe pit was logged, it was backfilled. It should be noted that the activity as shown on Map 24, Surface Facilities, would be within the boundary of the existing sediment control . system. The bathhouse/office facility replaced the former bathhouse trailers, and was constructed adjacent to the operations center as indicated on Map 24. The existing water and sewer systems were utilized for the new facility. The former trailers were removed during the summer of 1993, with a portion of the resulting open area becoming part of the parking lot. Water and sewer lines from these trailers were capped and covered. Approximately 3,000 cubic yards of material was removed during excavation for the foundations and slab, and approximately 400 yazds of compacted backfill material was used for the foundations and slab. In addition, some 850 tons of gravel was compacted beneath the foundations and slab. No other excavation work is planned. A limited amount of additional dirt-work included contouring of the pazking lot azea where the current administration trailer and pazking is located, and a possible widening of the access road by some 25 feet, should this become necessary in the azea of the new bathhouse facility. The parking azea was surfaced originally with tar-sand material, but this material has been overlaid with asphalt, and drainage will be conveyed via the existing system. The original building is of concrete block constmction and has dimensions of approximately 200 x 75 feet. Approximate height of the building is 15 feet. The building was placed on a reinforced spread-footer foundation and has a reinforced concrete slab floor. In 2003, under MROl-173, aten-foot expansion to the south was constructed for the bathhouse area only, providing an additional 1,000 square feet of locker room for the workforce. The extension design and structure matched the existing building. The extension required construction of piers, footings and walls and a concrete slab. The extension itself is constructed with wood framing, insulation, and metal exterior sheathing and roof. A mine warehouse and maintenance shop facility underwent a change in use and now houses a general meeting area and office space for mine personnel. TCC utilizes the former CYCC shop/warehouse complex to work on equipment and store and dispense materials. TCC also utilizes a shop area northeast of its office; the shop was • previously operated by CYCC as the Preventive Maintenance Bay. Uses of the shop area include construction, maintenance, and storage of materials, equipment, and various supplies. Access to the 2.5-acre shop facility is designated on Map 24, Surface Facilities. The parking area east of the above-referenced building is being improved to allow better utilization of the azea. The improvements required hauling in approximately 2,500 CY of spoil material to fill in the existing pazking azea and raise it so that runoff drains to both the north and south from this azea. Drainage from this azea is directed into ditches D-2, G-4, and D-6 (a and b). Design information for these ditches is contained in Exhibit 8. A small building has been constructed on the east side of the portal entry. The 10 x 12 x 8 foot building will house the portal slope heating system. 2005 Bathhouse Addition (MROS1951 An expansion to meet future coal production requirements for the mine will require approximately 100 new employees. As a result, an addition to the existing bathhouse facility is required. The addition will be constructed on the south side of the existing bathhouse facility, connecting to the existing bathhouse. The addition will be located on a portion of a previously compacted asphalt-coated parking lot. Existing water and sewer systems will be utilized for the new facility. Roof water will be segregated and rerouted to an existing pump-line at the portal leading to the Area 1 Pit. This water is eventually utilized for underground dust control and at the wash-plant. Existing surface drainage structures in the area of the addition will remain in place. The perimeter for the addition will be excavated to a depth of four feet for placement of a concrete foundation. The center portion will be excavated to approximately two feet, evaluated for compaction and backfilled. Additional .engineered-fill material will be imported to the site, as required. (See construction design or as-builts for greater detail). Foundation work will require construction of piers, footings, walls and a concrete slab. Building MR07-220 2.05-18 08/29/07
