recovered from the stockpile area. A total of approximately 550,000 tons of low- quality coal /coal refuse were <br />transported to, and subsequently recovered from, the designated permanent disposal site. <br />• Construction of Washplant I during 1994 and 1995 eliminated the need to haul the low- quality coal, discussed in <br />the above paragraph, to the permanent refuse pile. The plant was originally designed to have the capability to <br />produce 500,000 tons of clean coal per year during a seasonal operating period of April through September, with <br />the potential to produce at higher levels by extending the operating period. Internal plant modifications and <br />progressive extension of coal washing operations to a year -round schedule have resulted in an increase in <br />throughput capacity to a maximum of approximately 1,200,000 tons of clean coal per year. It is anticipated that <br />actual clean coal output will range from approximately 700,000 to 1,200,000 tons per year, dependent on demand. <br />In order to produce this amount of clean coal, approximately 1,120,000 to 1,950,000 tons of low - quality coal will <br />be processed through the plant. With these throughput rates, approximately 420,000 to 750,000 tons /year of refuse <br />would be generated and hauled to the approved refuse pile. <br />In order to finalize the designs for the permanent waste rock disposal site, field studies were undertaken and <br />completed during the second quarter of 1992. The required field studies were conducted during late May and <br />included a site reconnaissance, test borings and excavation of test pits. The location of the drillholes and test pits <br />are shown on Map 23A. The following describe the proposed (and subsequently conducted) field studies for design <br />and construction of the waste rock disposal facility. <br />The borings will be approximately 80 feet deep, dependent upon spoil depth in the area. It is anticipated that the <br />borings will be made by an auger, or if this is not possible a rotary rig will be utilized. It may be necessary to <br />construct a pad for the auger or drill rig, and if so it will be approximately 30 x 30 feet. If it is necessary to <br />construct the pad the available topsoil will be salvaged and stockpiled for final reclamation of the pad. The topsoil <br />may range in depth from 12 to 20 inches. All of the sites are located within an existing sediment control system, <br />therefore, secondary sediment control will not be needed for the pads. <br />• It is planned to drive the auger or drill rig to the proposed boring locations without constructing roads or a pad. <br />This is dependent upon ground conditions. If conditions are such that excessive rutting will occur, then topsoil will <br />be windrowed to the side of the road and pad. Existing roads will be utilized to the extent possible to minimize <br />disturbance. The borings will be made and the holes will be backfilled or grouted, unless it is determined that a <br />monitoring well should be constructed to monitor water levels in the spoil or bedrock. Any borings converted to <br />monitoring wells will be added to TCC's existing hydrologic monitoring plan. At such time, the appropriate <br />completion information will be forwarded to the MLRD, along with a monitoring schedule. Based upon final <br />location in the field it may be necessary to level an area for the rig. If this is required the topsoil will be salvaged <br />and placed to the side of the pad. The site will then be leveled to allow for safe operation of the rig. Upon <br />completion of the boring the pad will be regraded to blend in with the existing topography and the topsoiled. The <br />site will be seeded with Colorado Yampa Coal Company's (permit C -81 -071) approved pastureland seed mixture. <br />The test pits will be excavated utilizing a backhoe. It is anticipated the test pits will be approximately 15 - 20 feet <br />in depth. The excavated material will be placed next to the pit, and after testing and observations within the pit are <br />completed, the test pit will be backfilled. Sufficient vegetation should be available that the test pit will not require <br />seeding. If seeding is necessary the above referenced pastureland seed mixture will be utilized. <br />Discussion relative to the coal handling structures at the Fish Creek Tipple can be found on page 2.05 -33 of the <br />Fish Creek Tipple /Loadout Appendix, Volume VIII. <br />Rail Car Off - Loading Site <br />Loaded train cars must occasionally be unloaded in order to meet weight restriction requirements imposed by the <br />railroad. Front -end loaders are utilized in these instances to remove coal from individual cars identified as being <br />overloaded. To the extent possible, coal from overloaded cars is redistributed to cars with remaining capacity. In some <br />• instances, however, redistribution is not possible and coal must be temporarily placed on the ground. <br />MR08 -230 2.05 -89 09/05/08 <br />
