West Elk Mine <br />Man-made surface structures exist on the coal lease area and within the South of Divide and Dry Fork <br />mining areas (Exhibit 32B and Map 67). These man-made structures which are currently used for <br />intermittent or seasonal use include Monument Dam - Minnesota Reservoir (Exhibit 74), the lower <br />Cow Camp, the Deep Creek flume (a raised culvert), and the ditch rider's cabin. The cattle camp on <br />the Dry Fork of Minnesota Creek is a wood -framed building on a concrete slab completed by the <br />landowner in October 1994 with a smaller wood -framed building and livestock enclosure constructed <br />in November, 1995 (see Exhibit 73). A deteriorated and collapsed cabin exists in Sylvester Gulch, and <br />the remnants of soil and stone foundations of two buildings exist on a small bench overlooking the <br />mine portal. The remains of three log structures, possibly a cabin, barn and shed, are located in Lone <br />Pine Gulch. Several similar abandoned structures exist on the Jumbo Mountain lease tract (see Exhibit <br />10A and Exhibit 10B). Other abandoned structures in the permit area, are described in the Cultural <br />Resources Reports in Exhibits 10 through 10E. Projected subsidence -related impacts to these <br />"structures" are addressed under the permit section entitled "Effects of Subsidence and Mine -Induced <br />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 coal lease COC -67011. Known springs and renewable <br />resource lands in the Raven Gulch drainage are not within the affected area associated with <br />mining of the West Flatiron coal lease tract. The only notable man-made structure potentially <br />influenced by mining activities within this coal lease is Highway 133. The potential impact to this <br />• structure is indirect by reactivation of known landslides south of the highway and north of B -seam <br />longwall panel 18A. Impacts from, and monitoring of, this potential reactivation are addressed <br />under the worst possible consequences discussion associated with mine -induced subsidence under <br />(Landslides) below. <br />• <br />Description of Possible Subsidence Consequences — Z05.6(6)(b)(I) <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 Rev. 06/05- PRIO, 03/06- PRIO, 04/06- PR10, 05/06- PRIG, 11106- TRI07, 09/07- PR12, 02/08- PR12, 04/09- TR117, 11/10- 78114 <br />- !z¢ V1 A, <br />
