Revised 11/15/81 <br /> in each lift is normally less than 6 inches. Small size consists result <br /> from the continuous miner operation and the operation of the Bradford <br /> Breaker itself. In addition, compaction and placement of the lifts also <br /> tend to decrease the size of the material . Therefore, compaction of the <br /> material is quite easily attained. The third process utilized to <br /> construct the coal processing waste bank is to slope the face of the <br /> bank to a maximum slope of 2 horizontal to 1 vertical . Completion of <br /> grading this relatively gentle slope is by crawler tractors. The gentle <br /> slope enhances the erosion control of the slope and the subsequent <br /> reclamation of the coal processing waste bank. In addition, the slope <br /> increases the stability of the coal processing waste bank over a long <br /> term period. <br /> Material , other than coal processing waste which is generated by normal <br /> operation of the Maxwell Mine, is disposed of in two separate ways. <br /> Trash waste consisting of paper, cans, rags, and other assorted minor <br /> industrial waste associated with the general office, shop, and warehouse <br /> areas is placed in dumpsters and hauled to the Las Animas County <br /> Sanitary Landfill for disposal . Other waste material such as machinery, <br /> scrap iron, equipment, which has some salvage value, is placed in the <br /> scrap storage area shown on the Mine Plan Map (Map 3). The control of <br /> the surface water which originates in this area, as shown on Map 13, is <br /> by use of a hay bale sedimentation fence. This sedimentation fence will <br /> be constructed of hay bales placed side by side and end to end to <br /> prevent water and runoff from circulating around the fence. Secure <br /> placement of each bale will be completed by two stakes. After the <br /> mining operation is completed, and during the reclamation activities, <br /> material , machinery, and other items left in the surface disposal scrap <br /> storage area will be removed and disposed of at the local sanitary <br /> landfill or other appropriate location. <br /> Petroleum products which are used in the normal mining operation will be <br /> collected and reclaimed where possible. Where local rejuvenation of the <br /> petroleum products is not possible, they will be sold to petroleum <br /> 2.05-25 <br />
