northern harrier, sharp-shinned hawk, northern goshawk, Swainson's hawk, golden eagle, and <br />American kestrel. Bald eagles and an osprey were sighted east of the proposed permit area. <br />Breeding Birds <br />Forty-one species of breeding birds were observed during the surveys. Species distribution observed <br />in specific habitats were: 28 species in bottomland areas, 20 species in mountain brush, 17 species in <br />aspen, and 15 species in sagebrush. <br />Small Mammals <br />Six species of rodents and one species of shrew were captured during the survey. <br />Other Mammals <br />Other mammals observed during the survey were porcupine, yellow-bellied marmot, coyote, red <br />squirrel, and bat. Species identified by sign but not observed were badger, beaver, and skunk. <br />Four species of high federal and state interest were observed on or neaz the proposed Yoast Mine <br />permit azea. Those species are: <br />Columbian sharp-tailed grouse (Colorado DOW endangered species) <br />Greater sandhill crane (Colorado DOW endangered species) <br />Bald eagle (Federal and Colorado endangered species) <br />Northern goshawk (Federal candidate for endangered species listing). <br />Description of the Operation and Reclamation Plans <br />The coal was mined by surface mining methods, beginning in the northern section of the permit <br />boundary, then progressing south in subsequent permit terms. The majority of the coal was mined <br />from the Wadge seam, the exception being the mining azea located in the southwest part of Section <br />20 and the northwest part of Section 29, where Wolf Creek Coal was mined. The initial boxcut was <br />located in the northern portion of Section 17, and progressed upgradient to the southeast. Mining in <br />subsequent permit terms continued in the neck area, and moved southward through the eastern <br />portion of Section 17. Mining was also completed in Sections 19 and 20 and small portions of 18, <br />29 and 30. <br />The Wadge coal seam is overlain by 50 to 60 feet of sandstones, with interbedded shales and <br />siltstones. The thickness of the Wadge coal mined is approximately 9 to 13 feet. The Wolf Creek <br />coal seam is overlain by 150 to 215 feet of sandstones, shales, siltstones, and thin coals. The Wolf <br />Creek seam, in the area mined, ranges from 12 to 18 feet in thickness. <br />Production rates at the mine for the first and second permit terms ranged from 137,000 tons per year <br />to 1,031,330 tons per year. The mine operated through 2005, producing a total of 7,603,710 tons of <br />coal. <br />Yoast Mine 16 February 28, 2006 <br />
