During the permit term, development and coal-processing wastes will be produced from mining in <br />the B-Seam. Two-cycle mining on development and ventilation construction activities will be the <br />primary sources of waste from the B-Seam. Some waste may also be generated from the continued <br />rehabilitation of the F-Seam main ventilation and access entries. With the crusher, screens and <br />rotary breaker circuit, the least amount of coal processing waste will be produced. <br />All refuse generated during this permit term will be disposed in the Lower Refuse Pile and the RPE <br />area. The Lower Refuse Pile will reach its maximum storage capacity in 1997. Estimates of the <br />annual waste production and storage capacity of the RPE azea refuse aze shown in Exhibit 70. <br />These conservative estimates show that the RPE disposal area will handle all the waste generated <br />during this permit term. <br />(9) Return of Coal Mine Waste to Abandoned Workings <br />Mountain Coal Company does not return coal waste generated from the mine to its abandoned mine <br />workings at the West Elk Mine. All refuse is disposed of in the Lower Refuse Pile and RPE azea. <br />(10) Return of Coal Processing Waste to Abandoned Workings <br />Mountain Coal Company does not return coal processing waste generated at the West Elk Mine to <br />the underground workings. All coal refuse is disposed of in the lower refuse disposal azea. <br />(11) Disposal of Non-Coal Waste <br />Temporary disposal of non-coal waste (trash, gazbage, lumber or other items identified in Rule <br />4.11.4) is in a solid waste compactor which is located in one of the concrete bins neaz the portal <br />area. The location of these bins is identified on Map 53 as "Dumpster and Materials Storage <br />Bunker Area." The compactor system is designed to handle all the West Elk Mine solid waste <br />including spools, pallets and some metals. There aze several trash barrels/small dumpsters for <br />employee use in the facilities area, but these aze relocated when full to the compactor. The roll off <br />unit for the compactor is picked up by a contracted disposal firm when it is full, and replaced with <br />another unit. Final disposal of non-coal waste is at the Delta County Landfill, a State approved <br />facility. <br />No solid waste disposal (as addressed in Rule 4.11.4) is allowed at any refuse disposal azea. <br />2.05-44 Revised Jan /997 TR79 <br />
