West Elk Mine <br />Man-made surface structures exist on the coal lease area and within the South of Divide permit <br />revision area (Exhibit 32B and Map 67). The only known man-made structures which are currently <br />used (intermittent seasonal use) are Monument Dam - Minnesota Reservoir (Exhibit 74) and a cattle <br />camp on the Dry Fork of Minnesota Creek with a wood-framed building on a concrete slab completed <br />by the landowner in October 1994 and a smaller wood-framed building and livestock enclosure <br />constructed in November, 1995 (see Exhibit 73). A deteriorated and collapsed cabin exists in Sylvester <br />Gulch, and the remnants of soil and stone foundations of two buildings exist on a small bench <br />overlooking the mine portal. The remains of three log structures, possibly a cabin, barn and shed, are <br />located in Lone Pine Gulch. Several similar abandoned structures exist on the Jumbo Mountain lease <br />tract (see Exhibit IOA and Exhibit 1013). Other abandoned structures in the permit area, are described <br />in the Cultural Resources Reports in Exhibits 10, 10A, IOB, IOC, IOD, and IOE. Projected subsidence- <br />related impacts to these "structures" are addressed under the permit section entitled "Effects of <br />Subsidence and Mine-Induced Seismic Action on Man-Made Structures and Renewable Resources". <br />Based on field evaluation of the West Flatiron lease area, there are no structures or renewable <br />resource lands within the boundary of COC-67011. Known springs and renewable resource lands in <br />the Raven Gulch drainage are not within the affected area associated with mining of the West <br />Flatiron lease tract. The only notable man-made structure potentially influenced by mining <br />activities within the least tract is Highway 133. The potential impact to this structure is indirect by <br />reactivation of known landslides south of the highway and north of Longwall Panel 18A. Impacts <br />from, and monitoring of, this potential reactivation are addressed under the worst possible <br />consequences discussion associated with mine-induced subsidence under (Landslides) below. <br />Description of Possible Subsidence Consequences - 2.05.6(6)(b) (b <br />Pre- and Post-mining Land Uses -2.05.6 (6)(b)(i)(A) <br />As indicated in the Mountain Coal Company Coal Methane Drainage Project EA (February 2002), <br />North Fork Coal EIS (2000), and Environmental Analysis U-94-37 (November 1994), prepared by <br />the U.S. Forest Service (USFS) and U.S. Bureau of Land Management (BLM), in cooperation with <br />the U.S. Office of Surface Mining (OSM) and other jurisdictional agencies, the permit area lands <br />support wildlife use, dispersed recreation, and livestock grazing. <br />The Forest Service Amended Land Resource Management Plan prescribed land use designations of the <br />Box Canyon lease tract, South of Divide permit revision area, and surrounding USFS lands as "5A", <br />"613," and "9A" which emphasize riparian, wildlife habitat, and livestock grazing, respectively, <br />2.05-109 Revised 06105, 03106, 04106 & 05106- PR10;11106- TR107; 09107 & 02108-PR12; 04109- TR117
