become necessary in the area of the new bathhouse facility. Water and sewer lines from the trailers were capped and <br />covered. <br />In 1995, another temporary office trailer with dimensions of 24 x 66 x 12 feet was leveled and blocked south of the <br />administration building. There were no water and sewer hook -ups, and a 40 -foot long buried conduit brought in <br />power from an existing transformer. The location is delineated on Map 24. Bonding calculations addressing the <br />temporary office trailer are presented on page 2.05- 54(f)58. <br />In 2003, under MR01 -173, a ten -foot expansion to the south was constructed for the bathhouse area only, providing <br />an additional 1,000 square feet of locker room for the workforce. The extension design and structure matched the <br />existing building. The extension required construction of piers, footings and walls and a concrete slab. The <br />extension itself is constructed with wood framing, insulation, and metal exterior sheathing and roof. <br />2005 Bathhouse Addition (MR05 -195) <br />An expansion to meet future coal production requirements 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 parking 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 structures 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 -arch 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 parking 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 />Main Parking Area <br />Parking for the administrative staff and miners is located east of the bathhouses. The parking area was originally <br />surfaced with tar -sand material, but this material has been overlaid with asphalt, and drainage will be conveyed via the <br />existing system. In order to accommodate parking requirement for mine employees and visitors, the layout of the <br />parking area has been modified as shown on Map 24. As shown on the map, parking islands have been constructed <br />to establish parking corridors and walkways in the parking area. The parking islands have curbs made of railroad <br />track and concrete light pedestals. Connections from the light pedestals extend to elevated outlet boxes which <br />provide cold- weather plug -ins in the parking area. <br />Three additional parking islands were permitted and constructed in 1995, as shown on Map 24. The new parking <br />islands are consistent in design with the existing islands. There are two parking islands per line of cars. Each <br />island is equipped with 8 electrical receptacles hung on a one -rail structure supported by an oblong railroad rail <br />base. Bonding calculations addressing the new parking islands are presented in Appendix A. Drainage around the <br />parking area was modified as per the details provided on Map 24. The ditch between the current parking area and <br />access road was filled and runoff will be directed into Ditches D-4 and G4. The guard shack was converted into a <br />storage building and it is located on the west end of the mobile equipment parking/material storage yard. <br />In 2005, the unpaved eastern portion of the existing parking lot (approximately 130 x 180 feet) and the mine ready -line <br />parking area west of the operations center, were leveled and regraded, with excavated material being used to fill -in and <br />bring low areas up to a consistent grade. Road -base material was subsequently brought in and compacted over the <br />regraded parking areas to establish a suitable base for paving operations. These areas were then paved with <br />TR10 -75 2.05 -17.2 08/!9/10 <br />
