One (1) AUM requires 8101bs. of forage <br />45 days (x) 112 animal units = 5,040 animal days (/) 30 days = 168 animal months (x) 1.0 = 168 <br />AUMs <br />1,8041bs/acre (x) 798 acres = 1,439,5921bs of forage available <br />810 lbs (x) 168 AUMs = 136,080 lbs of forage required <br />Therefore; <br />136,080 (/) 1,439,592 (x) 100 = 09.4 % utilization of the entire Yoast Reclaim. <br />SEDIMENTATION POND SURVEYS <br />SCC is required by Permit C-82-057 to monitor sedimentation ponds for sediment storage capacities. <br />In accordance with Rule 4.05.6(11)(c), SCC visually inspects each pond a minimum of quarterly each <br />year. During these inspections, any drastic change in sedimentation storage or sudden increase in a <br />sediment delta at the inlet to the pond could be detected which would require mitigation. <br />Based on the 2009 survey, all sediment ponds have sufficient sediment storage. Additionally, all ponds <br />have been discharging in compliance with the approved NPDES permit effluent limitations. Yearly <br />sediment delivery estimates to the ponds are considerably less than originally calculated, since <br />significant portions of these watersheds have now been revegetated. <br />The results of the annual survey are shown on Table 09.6, Sediment Pond Capacities. <br />• STOCK TANKS <br />No stock tanks were constructed in 2009. <br />WILDLIFE MONITORING <br />Seneca Coal Company contracted Jones and Stokes to conduct wildlife monitoring at the Seneca <br />Yoast mine. The work included: <br />1. Monitoring known Sharp-tailed and Sage grouse leks and checking for new ones (April 28 <br />and 30, 2009) <br />2. Checking golden eagle nests (April 28, 2009) <br />The 2009 survey is presented in the attached Wildlife Monitoring Report. <br />LITERATURE CITED <br />2008 Annual Reclamation Report, Yoast Mine, Routt County, Colorado. Submitted to the Division <br />of Reclamation, Mining and Safety in March 2008 by Seneca Coal Company, Hayden, <br />Colorado. <br />Yoast Mine. Permit Application Package, Permit No.C-80-005 <br />
