Section 780.12(b) Continued. into the secondary crushers for reduction to the 2" X 0" size. After secondary crushing, coal is conveyed from the secondary crusher building on a sixty inch belt into a hopper in the sampler building where coal samples can be taken for quality analysis. Once the coal passes through the sampler building, it is conveyed on a sixty inch wide belt for discharge through a stocking tube into the crushed coal stockpile. The coal is then fed by gravity directly into unit trains which pass through a tunnel located beneath the crushed coal stockpile. The detailed flow sheets including air pollution control equipment for the Tipple No. 2 are diagrammed on Figure 19, Truck Dump - Tipple No. 2; Figure 20, Primary Crusher Building - Tipple No. 2: Figure 21, Secondary Crusher Building - Tipple No. 2; Figure 22, Sampler Building - Tipple No. 2; and Figure 23, Stockpile and Train Loadout - Tipple No. 2. All conveyors are completed with walkways on both sides of the belt and are • fully enclosed to control emissions. Bag houses are installed in the primary crusher building, the secondary crusher building, and the sampler building. Additional fugitive dust control measures for Tipple No. 2 are discussed in Section 780.15. Drainage from the Tipple No. 2 facility presently passes through sedimentation ponds as shown on Permit Renewal Map 5. These ponds, identified as B and C on Permit Renewal Map 5. have been redesigned to meet the performance standards of Subchapter K as delineated in Section 780.25. .~ CYCC requests a small area exemption for the small disturbed area surrounding the Loadout tunnel on the east side as identified on Permit Renewal Map 5 (Roads, Power Lines and Facilities). CYCC proposes the following sediment control for the small area exemption a seeded vegetative filter, and gravel filter dams in the ditches along the railroad track. The location of these facilities are shown on P.R. t4ap 5. 780-36 Revised 06/01/88
