Fish and Wildlife <br />Numerous wildlife species inhabit the general area of the mine site and tie-across haul road. The <br />most predominant big game species are elk and mule deer. Pronghorn antelope frequent the <br />vicinity of the tie-across haul road. Common raptors are golden eagle, red-tailed hawk, great <br />horned owl, marsh hawk and American kestrel. Use by greater sand hill cranes occurs in the <br />area of the tie-across haul road with an active staging area for these birds located approximately <br />0.75 miles north of the road. <br />Cultural and Historic Resources <br />The applicant conducted a number of site-specific literature searches and archeological surveys of <br />the permit area between 1979 and 1990. SCC has completed archaeological surveys of all <br />currently permitted and proposed areas associated with the extension. During these cultural <br />resource inventories, 10 sites and 5 isolated fords were identified. Of these only 2 were <br />considered significant; one rock art site with adjacent fire-rock and one potential large camp site. <br />The camp site will not be disturbed, and appropriate mitigation measures have been proposed for <br />the rock art/fire-rock sites. <br />Description of the Operations and Reclamation Plan <br />The Seneca II-W Mine is a surface mine operation. The mine is adip-slope, area strip mine <br />utilizing conventional dragline mining methods. In addition, auger mining has been employed in <br />certain locations. The Seneca II-W permit boundary encompasses two geographically separated <br />areas; the mine area permit boundary and the tie-across haul road permit boundary. The mine <br />area permit boundary includes three separate areas (North Block, South Block, and South <br />Extension) and associated facilities. The north and south blocks comprise the "original mine <br />permit area", while the South Extension was a permit area expansion approved within PR-2. <br />Mining was completed and coal extraction at Seneca II-W ceased in early January 2006. <br />The final areas mined were the Wolf Creek and Sage Creek seams in the South Extension <br />Area; mining had been completed in the original permit area several years previously. <br />Within the original permit area, Mine Pits A,B, C, and D were oriented perpendicular to the <br />cropline and the coal in the mine pit area dipped approximately 18 to 25%. A single dragline <br />operated alternately within the north and south areas. The Wadge coal seam was mined in all <br />four pits from the cropline to approximately 100 feet in depth. Auger mining was conducted <br />within certain final Wadge pit locations in the original permit area. <br />Mining in the south extension area was approved in PR-2 and subsequently initiated. <br />Development of this area proceeded directly from the final cut in the A pit. Wadge Coal pit <br />extraction and progressive development was parallel to the cropline. Mining is constrained by <br />Seneca II-W Findings Document 16 June 12, 2006 <br />Permit Renewal No. 5 <br />
