ROM Stoclmile (Located oear~ortal • Ongoing operations have resulted in recognition of the need to further increase available ROM stockpile capacity. In conjunction with site development and grading for future preparation plant construction, the existing ROM stockpile area was extended to the north and west as shown by Map 24. The expansion was graded so that the base of the pile slopes to the north toward relocated Haul Road B. Coal will be pushed over and reclaimed from this area by use of bulldozer or other similar type of mobile equipment. Most of the area, which was effected by the ROM stockpile expansion, was previously disturbed; therefore no topsoil remains. However, plant growth media recovery occurred for the small area, as shown on Map 24, between the existing Pond E embankment and Haul Road B. Up to 4,]70 cubic yards of plant growth media was recovered and stockpiled in stockpile (PPSP-2} located to the northeast. This material was salvaged from an area approximately 752 feet by 100 feet and 1.5 feet of plant growth media. The additional effected area was graded to drain directly to Pond E which was relocated in conjunction with preparation plant grading and stockpile expansion activities. The relocation of Pond E required the removal of approximately 9,300 CY of topsoil. The topsoil depth is approximately 28 inches and the area of the pond is approximately 150' x 720'. Approximately 3,000 CY of the topsoil was placed in stockpile SF-4, while the remaining 6,300 CY was placed in stockpile PPSP-1. The location of the stockpile is shown on figure 11C. Table 49a has been revised to reflect the above topsoil and plant growth media salvage volumes. The storage area and ramp will be reclaimed when the tipple facility is no longer required for processing mn of mine coal. The area will be returned to rangeland and planted with the appropriate seed mixture. Truck Duma The truck dump consists of a three-sided hopper. Historically, bottom or rear-dump trucks discharged coal into the hopper, or a dozer pushed coal into the open side of the hopper. It is anticipated that dozers will be utilized primarily to reclaim the coal from the stockpile and push it into the open side of the hopper. However, scrapers may be used to pick up coal from the stockpile and dump it into the truck dump. If needed to increase stockpile reclamation attack/shovel operation may be utilized for hauling stockpiled coal to the hopper. In order to increase the efficiency of the coal conveying system a belt was constructed from the crusher building to the R-O-M stockpile. The coal is either transferred into the crushing system or discharged onto a belt leading to the R-O-M stockpile. At the stockpile, the coal will free fall off the end of the conveyor onto the existing stockpile. The coal is pushed out from the stacker by a dozer, or it may be picked up by a scraper, or truck/shovel operation for transport to further reaches of the stockpile The belt structure over to the stacker is elevated, and partially enclosed. The belt requ'ved a minimum of two bents and a drive building. The drive building is approximately 20' X 20' X 20', and constructed on a slab and footers (1' X 4'). During final reclamation the conveyors and stoker will be tom down and removed from the site. The foundation for the building will be covered during the regrading of the area. Crushing and Sampling Facilities Apron feeder's dischazge the coal onto aseventy-two inch wide transfer conveyor belt, which feeds the coal into the primary crushing building. The coal is transferred from the truck dump belt into the coal processing facilities. The coal passes through the primary crushers and is reduced to an 8" X 0" size. Following primary crushing, the coal is discharged onto asixty-inch wide conveyor belt. This belt feeds the coal from the primary crusher building into the secondary crusher building. The coal is passed over vibratory screens and coal that is less than 2" X 0" is passed onto the belt leading to the sampling building. • APPROVE® APR 2 4 2000 Permit Renewal No. 3 2.05-32 12/10/98
