A vicinity map and a site map are provided as Figures 1 and 2, respectively. <br />3.2 GENERAL FACILITY AND PROCESS DESCRIPTION <br />Site Description <br />Trapper Mine is categorized by Standard Industrial Classification {SIC) Code 1221. Trapper <br />Mine is a surface coal mine that operates on a pernvtted area of more than 10,300 acres. Mining <br />operations are conducted along the northern flank of the Williams Fork Mountains to recover <br />multiple seams of high quality, low sulfur, subbituminous coal for delivery to the adjacent Craig <br />Station power generating facility. Elevations at Trapper Mine range from approximately 6,300 to <br />• 7,400 feet above mean sea level. The average annual precipitation is 16.7 inches, with about <br />one-third of this amount from snowfall. Site soils are well developed, generally deep and formed <br />in alluvium, and colluvium derived from sandstone and shale parent materials. Topographically, <br />cultivated lowlands give way to rolling upland hills and long steep slopes historically utilized as <br />rangeland and wildlife habitat with steeper slopes occurring in the higher elevations. <br />MlninP and Reclamation Operations <br />Surface mining operations commenced at Trapper in 1977. Conventional dragline mining is <br />utilized for stripping overburden from the coal seams. Three Page 752 LR draglines (32 cu yd <br />buckets) operate concurrently in different areas of the mine. Coal is loaded into large {95 ton) <br />haul trucks with hydraulic excavators/shovels. Coal is hauled drrectly to the Craig Generating <br />Station, where it is used for the production of electricity. Reclamation consists of ,grading the <br />overburdern (or spoil), replacement of topsoil, and revegetation with a mixture of grasses, forts, <br />and shrubs <br /> <br />
