Recreation <br />1. Aside from surface facility areas, no public land access would be restricted by mining <br />activities. Signs would be posted advising the public of any mining activity and any road <br />construction activity. Cones and gates would be used when necessary to limit. access or divert <br />traffic at mine surface facilities. <br />Air Quality <br />1. To control dust emissions, the Operator would cover haul truck beds with tarps for off site <br />transportation of ore. <br />2. To control emissions from vent holes, watering of underground operations would take place to <br />reduce dust generation underground. <br />3. The Operator would spray water or chemical suppressants as needed on the storage piles to <br />reduce fugitive dust. Emissions from the topsoil storage piles would be controlled by vegetation <br />that has been or, would be established on the piles. Dust emissions from storage piles must meet <br />the 20 percent opacity limit specified in the Operator's air permit. An EPA-trained employee of <br />the Operator would monitor opacity once every two weeks. <br />4. The Operator would control fugitive dust for the on-site roads by enforcing low speed limits <br />(i.e., 25 mph for haul trucks on the county road) and applying magnesium chloride, calcium <br />chloride, or equivalent to the haul roads within the mine portal area as needed to reduce fugitive <br />dust. The frequency of chemical suppressant applications would depend on site-specific <br />conditions such as precipitation, road dust silt content, and traffic type and volume. <br />5. The Operator would water or chemically stabilize unpaved roads (i.e. CR 20R) as determined <br />by the Operator and BLM and in conformance with San Miguel County regulations and permit <br />conditions. <br />6. The Operator would restrict vehicular travel vehicles to established roads to the extent <br />practical. <br />7. The Operator would minimize, the area of disturbed land. <br />8. The Operator would revegetate disturbed surface areas. <br />Cultural Resources <br />1. If access roads are proposed to be utilized for drilling operations cross through eligible <br />cultural properties, the BLM would require temporary protective fencing during drilling. <br />operations (including reclamation) to protect them from surface disturbance or inadvertent <br />damage. A BLM or BLM-permitted archaeologist familiar with the boundaries of these sites <br />would direct the placement of the fencing which would be placed by hand. All fencing would be <br />removed upon the completion of the exploration and associated reclamation activity.
