following sections. A water intake gallery located adjacent to the Purgatoire provides <br />• water for the operation. Water is pumped either directly to the plant, to water tanks <br />located on higher ground south of the preparation plant, or to pond #1 for storage. <br />Water is piped from the storage tanks to the preparation plant and buildings at the <br />site. The slurry disposal system will deposit coal waste slurry to the abandoned <br />underground workings, and a well located north of the prep plant will recover water <br />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 <br />was removed. This facility will be reinstalled for use as a bleeder fan ventilating the <br />West Mains area. As the projected life of this facility is unknown, it is planned to <br />power this installation with a diesel/electric generator or portable substation. The fan <br />site has not been reclaimed 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 <br />Portal and Map 12 Surface Facilities and Roads West Portal. Major facilities are <br />listed on Table 19 Surface Facilities List. Exhibit 28 Bond Calculations contains <br />a detailed description of all facilities and respective construction types. In general, <br />structures are built of structural steel, sheet metal, brick and mortar with concrete <br />• foundations. As shown on Map 15, the majority of these facilities and structures are <br />built on natural ground with coal stockpiles, refuse disposal and materials storage <br />located on pre-law fill areas. Other than the RDA and the sediment control system <br />(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 <br />removed or demolished with salvaged materials shipped off site and inert debris <br />buried at approved locations on-site. As shown on Map 16, most of the facilities are <br />located on native soils as opposed to refuse fill areas. As mine recovery progresses, <br />the West Portal air shaft will be reopened. A small fan powered by a diesel/electric <br />generator or portable substation will be set over the shaft to provide ventilation for the <br />West Mains. An access road will be maintained from the Mine entrance road to the <br />fan and air shaft. A small graveled parking area will be maintained adjacent to the <br />fan. <br />Maps 15 and 16 show disturbed areas on the site. The disturbance area boundary has <br />been established to include a buffer should additional disturbance activities become <br />necessary. The surface disturbance boundary shown on maps 15 & 16 will be the <br />boundary marked in the field in accordance with Rule 4.02. These markers will <br />consist of roof bolts or rebar covered with white PVC pipe. As portions of the site are <br />reclaimed, boundary markers will be moved to the reclamation limits of the disturbed <br />areas. <br />• Two facilities, Apache Canyon Air Shafts #1 and #2 were reclaimed and Phase III <br />released. These facilities will be returned to productive use for mine ventilation. The <br />TR-50 Page 2.05-5 Revised 3/28/09
