se~car- z.os.s point far the new batch-weigh loadout. Silo nmdificatians included madificatian of the headhotue to accommodate an increase in the width of the silo feed conveyor and address existing dust control concerns and ntodi£icatian of the discharge chutes and gates m feed a new batch-weigh loadout transfer belt az a rate of b,C00 [ons per hour. T1te new [roofer conveyer nu>.s from the silo discharge point to the aewbotch-weigh loadout constnrcted adjacent to the existing sidetrack to the east of the silo. The transfer conveyor includes partial covets for dust control, aralkways, and emergency stop cantrok for inspection and maintenance in campliutce with applicable MSHA safety regulations, Batch-Weigh Loadout and 5atnpling System - T1re new batch-weigh loadout, constructed in conjunction with the 1997-1998 coal handling facilities expansion, consists of a surge bin, batch weigh bin, traversing telescoping loading chute, and associated control and ancillary equip:Went, all of which are tornainetl in apre-engineered steel buildutg. The loadout system is designed to load a tutu train at a rate of appeaximuely 6,0t~1 tons per hour, allavring a full uxirt to be loaded in less than two hours. A two-stage coal sampling system is installed an the transfer conveyer from the silo. The system includes a printarysweep sampler, discharge chute, coal crusher, and secondary sampler, The primary sampler periodically sweeps a sample of coal off of the tt~arLSfer canve}er. The sample falls into a chute chat delivers the coal to a small crusher and a secondary sampler. T-he reject coal is conveyed back to the transfer conve}trr by a screw auger. T1re entire sampling system is enclosed in a srtta$ ttmtal building. C,;oal ~tg[tr~g and 1Vam al~'t~Es~~rg Waste General and detailed plans for coal reftse piles are described and referenced in the faAowing sections in full compliance wixh applicable provisions of Rules 4,16 and 4.11. These plans have been prepared by ar under the direction of a qualified Registered professional Engineer, are illustrated by maps and drawings as referenced in the plan discussions, and include relevant geologic and hydrologic information, geotechnical evaluations, as applicable; descriprions of operation and mairnenance requirett[ents for each disposal structure; and plate tar stabili2ation and reclatttaaon of refuse piles. Refuse piles have been located beyend the subsidence limits for uttdergmund Honing areas, potential subsidence effects are not a concenr. The processing of raw coal from the Somerset Mare was limited to picking tables where roof rock and parting trraterial was ntanua$y rertx>ved from the tun-of-mute coal. These materials were placed in the East Yard Area along with development refuse generated by ongoing ttvne development. '17te picking tables were removed in 1964, and the poly refuse subsequendy plzced in this area included motor quantities of mine developtrtent refuse and material from roof falls. Most of the coal mine infuse previvusty plated in the East Yard area has been scanemd and blended with surface materials aver the ytan, with the result that no distinctive refuse pile rernairts in this area. Since the early 1980's, no coal processing has occurred anti the only infuse materials produced by ongoing mining and coal handling operations have been minor quantities of underground deveivprr~nz zfuse, coal refuse from roof falls, and coal refuse separated from the coal by the gri2zty in the dump station. These materials have been disposed of in the East Yard pile near the sealed Ct yearn mine portals as shown an Map CS• 1195A. During the six•year period from 1441 through 1497, the total quantities of coal mute refuse generated by ongoing mining operations were appmxintately 5,~0 cubic yards annttally. At this rate, the East Yard pile was projected to Mach capacity at some point during 1947 or early 1998. Given this time schedule, C?MT proceeded with identification, evaluation, design, and developmem of a new coal znisre refuse disposal area. In Conjunction with expazoion of the Elk Cmek coal stockpile, additional fill material was required to bring the stockpile pad up to the design grade. With the nrgged terrain an the area, potential fill barrow sources are limited and the material in the East Yazd pile was identified as potentially suitable fiU material for this application. Subsequently, approxtmately25,000 cubic }arils of material from the refuse pile were placed in the stockpile pad, opett[ng up appmxirnately #ive years of available drspasal capacity in the East Yard ama at current deposal races. 2,OS-4d Revised August 2000
