carbon monoxide and nitrogen oxides from vehicle exhaust as well as radon from the waste rock and ore stockpiles as well as ventilation exhaust fans. The most intense disturbance should be of short duration during clearing of the waste rock and ore stockpiles and the mine development activities. Dust from loading ore and waste rock would contribute to emissions as well as the dispersion effects of wind and storm systems. Dust resulting from mining operations would represent an incremental increase in particulate matter that is described as low and long term. Preferred Action Alternative -With the inclusion of the Best Management Practices such as seeding and dust abatement, this project would represent an incremental increase in fugitive dust over the life of the mine. After reclamation of the site there would be low to no increase in fugitive dust over the long term. No Action Altemative -There would be no impacts to air quality as a result of this project AREAS OF CRITICAL ENVIRONMENTAL CONCERN Affected Environment: No Areas of Critical Environmental Concem have been identified in the project area. Environmental Consequences/Mitigation Proposed Action -There would be no impacts to Areas of Critical Environmental Concem. Preferred Action Alternative -There would be no impacts to Areas of Critical Environmental Concem. No Action Alternative -There would be no impacts to Areas of Critical Environmental Concern CULTURAL RESOURCES Affected Environment: Human groups have inhabited the area during the past 10,000 to 12,000 years. They are characterized as Paleo-Indian huttters of big game; Archaic small game hunters and gatherers; and Formative, sedentary agriculturalists and proto-historic hunters and gatherers. The area has been disturbed by previous mining operations. in the vicinity of the proposed action there are exploration drill holes, naturally reclaimed drill roads and a vent shafr Environmental Consequences/Mitigation Proposed Action - Class I and Class I[I inventories for cultural resources of the mine site were conducted in January, 2006. No sites were found. There would be no effect on cultural resources. No known sacred sites or traditional cultural properties would be effected by the project. However, new information that may be discovered would not be protected. Preferred Action Altemative -With the inclusion of the Best Management Practices for cultural resources, any new information or sites discovered would be reported to the BLM and would be protected or mitigated. No Action Altemative -There would be no impacts to cultural resources.
