broadcast seed on the pile soon after the dozer finishes. Also covering the pile with excelsior <br />matting or jute netting will aid in establishing seed species. <br />6.4 Deer Road Kill Study <br />Per the monitoring requirement from the BLM, NSI compiled deer road kill data throughout 2006 <br />for vehicles traveling to and from the mine site. NSI received no reports of deer killed by <br />employees or contract vehicles in 2006.. <br />6.5 Raptor Survey <br />Per mitigation requirements of the BLM Record of Decision, annual raptor breeding activity was <br />monitored. Raptor breeding activity inventories aze conducted in the planned and current well <br />field to identify breeding/nesting areas. As a result of inventories, mitigation or modification of <br />drilling activity can be developed prior to disturbance. <br />In 2006, inventories of raptor transects were performed from May to July. Previously spotted <br />owl nests and red-tailed hawk nests were not rebuilt, or in use in 2006. No new nests were <br />spotted within the survey azea. <br />6.6 Other Observations <br />BLM removed excess numbers of horses in the Yellow Creek azea during the fall and that action <br />reduced the number that would have been normally observed. No wild horses were spotted <br />within the well-field. <br />Elk, deer, coyotes, and fox were noted in and azound the well-field throughout the year. <br />6.6 Waste Disposal <br />Common domestic solid waste is collected in containers and periodically transported to the Rio <br />Blanco County landfill. Sewage from the plant is directed to a septic system with drain field. In <br />2006, two drums of lab reagent waste and three dnuns of waste oil were shipped to an approved off <br />site facility for treatment and disposal. Although the lab waste aze considered hazazdous because of <br />chromium and silver content greater than EPA limits (5 ppm), new process have been introduced <br />that will eliminate the reagent waste. Process wastewater, including plant wash down and <br />contaminated precipitation runoff, was directed to the process pond. A pump in the process pond <br />allows NSI to recycle the water to the barren system. The wastewater pond stores water from the <br />cooling tower blow down, water softener brine and blow down from the boilers. <br />2007 Annual Report 18 of 18 <br />
