20, TSN R86W no longer serves as a power drop to the mine. The neazby North Escape Shaft has no facilities but exists as a completed 3 foot diameter shaft to be used only as an underground emergency extraction point for miners. The NMD vent shaft consists of associated buildings and a powerline. The 6 North Mains Ventilation Shaft site consists of a ventilation shaft, power drops, and a sedimentation pond. The Fish Creek Tipple (FCT) facility is located approximately 5 miles northeast of the main portal azea in Section 2, TSN R86W, about 7 miles downstream on Fish Creek from the FCB facility. It was originally permitted sepazately under permit No. C-81-036 but since has been incorporated into the Foidel Creek permit No. C-82-056. It consists of a rail loadout, crushing and screening equipment, conveyors, stockpile azeas, and a sediment control system of ditches and one pond. The FCT facility has been idle since Energy Mine No. 3 (No. C-84-062) completed mining in 1986, and is currently inactive. Locally significant are the rock units of Twentymile Park Basin which dip 5 to 30 degrees toward the central portion of the basin. Normal faulting has been identified throughout the permit azea, striking generally northwest to southeast, with displacement of zero to 85 feet. A reverse fault running in an azcuate line northward through the west central part of the basin shows displacement of 0-80 feet. Smaller lateral faults were encountered in the 9 Right (R) and l OR gateroads while driving development out into the Eastern Mining District. The near-surface bedrock units aze composed of sedimentary rocks of marine and non-marine origin. These sedimentary rocks were formed through the transgression and regression of an epicontinental sea and aze comprised of sequences of sandstones, siltstones, shales and coal. Four geologic formations exist in the vicinity of the Foidel Creek Mine. They are, in ascending order, the Mancos Shale, the Iles and Williams Fork Formation of the Mesaverde Group, and the Lewis Shale. These strata were all deposited during the late Cretaceous Period. Generally, the strata dip to the center of the basin. Three economically important coal seams, the Lennox, Wadge, and Wolf Creek coals, aze located within the locally important Middle Coal Group of the Williams Fork Formation. At this time, the Wadge coal seam is the only seam being mined in the Foidel Creek underground mine. The Wadge Coal seam was strip mined in CYCC's adjacent Energy Mine No. I, Energy Mine No. 2, and Eckman Pazk Mines (No. C-81-071), and Energy Mine No. 3 (C-84-062). The Wadge coal seam, in the area of the Foidel Creek Mine, is sepazated from the underlying Trout Creek sandstone by about 250 feet of interbedded sandstones, siltstones, shales and coals. The Wadge coal seam is sepazated from the overlying Twentymile sandstone by 700 feet of massive shale and interbedded sandstones, siltstones, shales and coals. Overburden depths in the current permit azea range from 0 to 1,700 feet. The stratigraphy and geologic structure within the Twentymile Park Synclinal Basin control the ground water flow within the permit and adjacent azeas. There aze three regional bedrock aquifers within the permit and adjacent azeas of the Foidel Creek underground mine. These aquifers aze the Trout Creek sandstone, the Twentymile sandstone, and the Wadge coal-overburden zone. All
