II. Support Facilities -Rule 4.04 <br /> A. Support facilities used in conjunction with the PSC include the following <br /> structures: various buildings (office, security, storage, electrical parts, bath house, <br /> pump house, vehicle shop, welding shop etc.), parking lot, fences, fuel tanks, lube <br /> storage area, fuel and oil storage area,power lines,electrical substation, conveyors, <br /> mine portal heaters, compressors, ventilation systems, water well,and material and <br /> storage yards. All facilities will be constructed to prevent damage or disruption of <br /> utility lines, water wells, railroads, and pipelines which may pass over, though, or <br /> under the permit area. <br /> III. Hydrologic Balance -Rule 4.05 <br /> A. Water Quality Standards and Effluent Limitations <br /> The Division proposes to grant a small area exemptions from use of sediment <br /> ponds due to the limited size of the area and due to the fact that ponds and <br /> treatment facilities are not necessary for the drainage to meet the effluent <br /> limitations of Rule 4.05.2 and applicable State and Federal water quality <br /> standards for receiving streams and also due to the fact that no mixing of <br /> surface drainage with a discharge from underground workings will occur. The <br /> small areas to be exempted are located on the north side of road A. They <br /> include the office area and two warehouse/boneyard areas (4.05.2(3)(b)(1)). <br /> B. Diversions and Conveyance of Overland Flow <br /> Twenty-three permanent postmine drainages have been constructed on the <br /> reclaimed Seneca II Mine. The channels are in various stages of bond release <br /> and have been constructed to their approximate original natural pattern for <br /> minimizing erosion, conserving soil moisture and promoting vegetation. <br /> Channel SCIIPM-1, the inlet to Pond 002, is a permanent channel draining a <br /> watershed greater than one square mile and is designed for a 100-year, 24- <br /> hour storm event. <br /> Thirteen permanent stock ponds are on the reclaimed lands of Seneca II Mine <br /> that were transferred to the PSC permit. The Phase III bond release request <br /> SL4 released certain stock ponds, ponds and spoil springs. Please refer to the <br /> SL4 Findings Document for further information. The stockponds were <br /> approved with TR35 to the Seneca II Mine permit. <br /> Page 15 of 27 <br />
