inch polyethylene LP line will be buried from the tank to the new bathhouse, and will include a vaporizer located <br />some 50 feet from the tank. <br />A Portal Waste Transfer Station will be constructed to replace the existing temporary waste storage area, and <br />provide for more efficient segregation and handling of mixed solid waste materials coming out of the mine. <br />Construction will involve minor excavation and placement and compaction of fill materials (roughly 600 cy), and <br />forming and pouring of reinforced concrete pads and back/wing walls (approximately 240 cy of concrete), as shown <br />on the construction drawings provided in Exhibit 49AA and on Map 24. The pad foundation and footer will be 8- <br />inch thick reinforced concrete, and the back- and wing -walls will be 10 -inch reinforced concrete, approximately 6 <br />to 8 feet high. <br />As an existing disturbed area, the proposed Portal Waste Transfer Station installation will not result in any new <br />disturbance, and will not require or result in any changes to existing drainage and sediment controls. Operation of <br />the Portal Waste Transfer Station will involve sorting of mixed solid waste materials coming out of the mine, and <br />selective placement of the different types of waste materials in labeled steel roll -off containers. Recycling or waste <br />disposal contractors will periodically pick -up the filled containers for transport off -site for recycling or disposal, <br />and replace them with empty containers. TC may also place a trash compactor in this area, to reduce the volume of <br />cardboard, paper, and other similar waste materials. The compactor would be powered by a drop -line from one of <br />the existing transformers or distribution lines which already exist. Reclamation on this installation will involve <br />burial in -place of the concrete pad and wing -walls in conjunction with the backfilling and regarding of the portal <br />area. <br />The Fish Creek Dewatering/Treatment facilities will be used for discharging mine water. Facilities to be <br />constructed at the Fish Creek Borehole Area are shown on the following maps; <br />Map 26, Fish Creek Borehole Area Facilities and Access Road <br />Map 27, Fish Creek Borehole Area Access Road Profile <br />Map 28, Fish Creek Borehole Area Access Road Profile and Typical Cross - Sections <br />Map 32, Fish Creek Borehole Settling Pond Plan view and Cross - Sections <br />The mine water discharge wells will be required in 1989. Total disturbed area required for the above facilities <br />would be less than 10 acres. Access to the sites would be as shown on Map 29, Reclamation. <br />Standard maintenance procedures, such as preventive maintenance programs, painting, and lubrication shall be <br />utilized throughout the life of all the structures. All facilities will be removed, and the area reclaimed to its original <br />use at the completion of mining activities, except to the extent that alternative postmining land uses are approved. <br />EASTERN AND NORTHERN MINING DISTRICTS <br />Mining in the Eastern and Northern Mining Districts (EMD/NMD) required installation of a new dewatering <br />facility and three fans. One of the fans (0 -Entry Fan — Robinson 85,000cfm) was installed in the 0 -Entry, <br />approximately 600 -800 feet inby the portal mouth (MR94 -107). The location of this fan places it within the current <br />Surface Facilities area, therefore, no new disturbance was associated with fan installation. The approximate <br />location of the fan is on the bench between the Stoker Coal Storage and Materials Storage areas, as shown on Map <br />23. This fan is of similar size and capacity as the existing main mine fan. <br />Two additional fans (EMD Fan Installation — Jeffrey 600,000cfm and Industrial Air 150,000cfm) were installed in <br />1996 -1997. The location of the fans is shown on Maps 17A, 18A, and 23. The fans were installed at the end of the <br />9 -Right Panel, and are used to augment the main mine fans. Installation of the fans required construction of an <br />access road into the site, installation of a diversion ditch upslope of the construction site, establishment of a topsoil <br />stockpile, grading of a construction site, extension of the existing powerline to the site, boring of ventilation shafts, <br />and installation of the fans and associated ancillary equipment. Approximately 2 acres were disturbed in <br />conjunction with upgrades to, and extension of, the road and construction of the fan site. <br />MR13 -268 2.05 -55 10/23/13 <br />
