material will be used on approved permanent roads or used as fill material for final grading of the highwall and facilities areas. The geo-grid will either be used for other road projects or disposed of, depending on its condition at the time of reclamation. The geo-fabric will be disposed of as solid waste. An appropriate seed mixture will be used for revegetation of the road corridor. • The wetlands area will be re -vegetated with vegetation native to the area as determined in . the wetlands delineation performed for this project. The total area of wetlands disturbed by this project will be approximately 0.01 acres. Upon reclamation of this roadway, TCC will seed a wetlands area of at least 0.10 acres to satisfy the U.S. Fish and Wildlife's request for a 2:1 mitigation of wetlands area disturbed by the crossing. The design for the Batch Loadout Haulroad has been revised to reflect that smaller equipment will be used to access the Batch Loadout for periodic cleanup of coal spilled from train cars. The revised design includes using 10 -ton dump trucks as opposed to the 100 -ton trucks covered in the original design. The revised design is presented in Exhibit 48-2. The original design will be kept active in the event it larger trucks are required the road would be upgraded to the previously approved design. The revised design calls for a top width of 24 feet, which is 6 feet less than the original design. The construction process will be the same as previously approved. Topsoil may be protected in one of two ways: 1) salvaging and stockpiling at the site, or 2) placing fabric over the top of the topsoil and then building the road over the fabric. After topsoil protection has been completed the road will be constructed as per the approved plan. 3G. Loadout Stockpile/Refuse Pile Access Road An access road was constructed to provide bulldozer access from the loadout stockpile area to the waste pile area during construction of the refuse disposal area. The road will tie the southwest side of the loadout stockpile to the northwest end of the waste pile, following an abandoned road -cut in the hillside above the loadout stockpile for approximately 100 feet, then will continue uphill for approximately 300 feet and cross the waste pile perimeter ditch • section RDA -lc into the waste pile area (see Map 24). The access road was designed and constructed in accordance with the design requirements of Rule 4.03.2. The design and certification is presented in Exhibit 25N, Refuse Pile North Access Road. Topsoil was removed and stockpiled in accordance with Rule 4.06. The area proposed for the 300 -foot access road section required stripping of approximately 16 inches of topsoil from a 30 -foot wide area. Approximately 444 cubic yards of topsoil was removed from this section and placed in Topsoil Stockpile SF -8. The lower 100 -foot section of access road is located in a disturbed area where topsoil has been previously stripped and stockpiled. Construction of this access road was completed in accordance with the specifications detailed in Figure 22, Access Road Typical Sections. Surfacing consists of a 12 -inch sub -base of 6 -inch minus pit -run rock surfaced with a two- inch layer of 11/cinch crushed rock. The access road crosses the waste pile perimeter ditch in section RDA -lc with a 40 -foot long 18 -inch CMP culvert installed at the crossing. Culvert sizing and installation is in accordance with Rule 4.03.2(4). Road drainage was directed to the west end of the road and into Ditch D-1. Reclamation of this access road will occur after the road is no longer needed for its intended purpose, and will include removal of the culvert, ripping of the road surface, topsoil redistribution, and revegetation. Topsoil will be redistributed over the road area and the area seeded with an appropriate seed mix during the first available planting period. 4. East and West Ramps to Portal Area The east and west ramps to the portal area were constructed in accordance with permit C-056-82, approved April 16, 1984. Locations may be found on Map 24, Surface Facilities. Profiles and cross-sections may be • found on Map 30, Road Profiles and Cross Sections. Overall grade does not exceed 10 percent.
