following sections. A water intake gallery located adjacent to the Purgatoire provides water <br />for the operation. Water is pumped either directly to the plant, to water tanks located on <br />higher ground south of the preparation pplant, or to pond #1 for storage. Water is piped from <br />the storage tanks to the preparation plant and buildings at the site. The slurry disposal system <br />will deposit coal waste slurry to the abandoned underground workings, and a well located <br />north of the prep plant will recover water from the slurry for reuse in the prep plant. <br />In the process of reclamation at the West Portal, the fan at the West Portal air shaft was <br />removed. This facility will be reinstalled for use as a bleder fan ventilating the West Mains <br />area. As the projected life of this facility is unknown, it is planned to power this installation <br />with a diesel/electric generator or portable substation. The fan site has not been reclaimed <br />and will not result in an increase in mine disturbance area. <br />(3) Mine Facilities <br />(a).(b).Structures <br />The existing structures are shown on Map 11 Surface facilities and Roads East Portal and <br />Map 12 Surface Facilities and Roads West Portal. Major facilities are listed on Table 19 <br />Surface Facilities List. Exhibit 28 Bond Calculations contains a detailed description of all <br />facilities and respective construction types. In general, a detailed description of all facilities <br />and respective construction types. In general, structures are built of structural steel, sheet <br />metal, brick and mortar with concrete foundations. As shown on Map 15, the majority of <br />these facilities and structures are built on natural ground with coal stockpiles, refuse disposal <br />and materials storage located on pre -law fill areas. Other than the RDA and the sediment <br />control system (ponds and ditches), all land disturbances at the site were pre -law. <br />All West Portal buildings listed on Table 19, Surface Facilities List, have been removed or <br />demolished with salvaged materials shipped off site and inert debris buried at approved <br />locations on -site. As shown on Map 16, most of the facilities are located on native soils as <br />opposed to refuse fill areas. As mine recovery progresses, the West Portal air shaft will be <br />reopened. A small fan powered by a diesel/electric generator or portable substation will be <br />set over the shaft to provide ventilation for the West Mains. An access road will be <br />maintained from the Mine entrance road to the fan and air shaft. A small graveled parking <br />area will be maintained adjacent to the fans. <br />Mining to establish a new ventilation pathway from the slopes to the East portal exhaust shaft <br />will require the temporary placement of a small conveyor drive, auxiliary ventilation fans and <br />a portable power system. It is expected that the temporary slope equipment will be in place 6 <br />months at which time they will be replaced by permanent installations or removed. <br />Maps 15 and 16 show disturbed areas on the site. The disturbance area boundary has been <br />established to include a buffer should additional disturbance activities become necessary. <br />The surface disturbance boundary shown on maps 15 & 16 will be the boundary marked in <br />the field in accordance with Rule 4.02. These markers will consist of roof bolts or rebar <br />covered with white PVC pipe. As portions of the site are reclaimed, boundary markers will <br />be moved to the reclamation limits of the disturbed areas. <br />Two facilities, Apache Canyon Air Shafts 91 and #2 were reclaimed and Phase III released. <br />These facilities will be returned to production use for mine ventilation.
