Section, 28 W'/zW'/z; <br />Section, 29 All; <br />Section, 30 E''/z; <br />Section, 31 All; <br />Section, 32 All; <br />Section, 33 W'/z; <br />Township 6 North, Range 92 West 6`h P.M. <br />Section, 25 (portions of the S%z); <br />Section, 26 S'/zSE'/a; - <br />Section, 35 W'/z; <br />Section, 36 All. <br />These lands encompass approximately 6,363 acres and are found on the USGS 7.5 minute <br />quadrangle maps of Round Bottom and Castor Gulch. <br />The mining operations used a combination of room and pillar and longwall mining methods to <br />recover coal from the Williams Fork "E" and "F" coal seams from 1971 until 1995. In <br />December1995, the mine was placed in temporary cessation and the only activity since that time <br />has been the pumping of water from the underground works to maintain a stable mine pool for a <br />return to production at some date in the future and the maintenance of environmental controls. <br />Mine facilities for portals, parking, shops, equipment storage, breakers, silo, load-out and other <br />support facilities have disturbed approximately 422 surface acres including the reclaimed <br />Williams Fork Strip Pit No. 2. <br />Specifically, RN-OS proposes to renew Colorado State permit C-81-044 for a period of five (5) <br />additional years. It is anticipated that the mine will remain in temporary cessation for the <br />majority of the renewed permit term. As a part of the permit renewal process CO-DMRS <br />requested that BTU Empire Corporation reexamine previous Threatened and Endangered species <br />consultations for the Eagle 5 & 9 mine to ensure that all listed and candidate species have been <br />addressed. <br />Site Description <br />The portals for the Eagle 5 & 9 mine are driven into the steep-sided walls of the valley that the <br />Williams Fork River has cut through the Williams Fork Mountains above its confluence with the <br />Yampa River at the northwest corner of the permit area.. Elevations of the permit area ranges <br />from 6,300 feet above mean,sea level in the Big Bottom area to 7,400 feet above mean sea level <br />at the Williams Fork Mountains. The vegetation communities within the permit area vary from <br />Cottonwood -willow riparian habitat along the rivers to juniper and big sagebrush on more xeric <br />sites. Lands disturbed by mining are dominated by upland big sagebrush and mountain shrub <br />communities. There are two types of crop lands within the permit area consisting of irrigated <br />hayfields in the river bottom areas and dryland wheat on cleared hillsides. <br />
