offsite for processing approximately every eight weeks. It is anticipated that the processing site <br />would be the White Mesa Mill at Blanding, Utah. <br />The operation would consist of site preparation by removing shrubs and trees from the mine, ore <br />and waste rock stockpile, and ventilation areas using a dozer and/or a backhoe. Minor leveling <br />of the area would be required. One to six inches of topsoil would be stockpiled for use when the <br />site is reclaimed. The mine portal entry would be 10 feet by 10 feet in sandstone. Silt fences and <br />berms would be installed for erosion control and storm water runoff. All storm water would be <br />retained on site; no water would be discharged offsite. Drainage from all affected areas would <br />run into a water retention pond capable of holding aten-year 24-hour precipitation event. <br />The mine site is adjacent to Montrose County Road Y 1. No additional roads are proposed at this <br />time. Existing roads would be maintained as needed. The County road standard is 15 to 22 feet <br />in width. Access is from Montrose County Road Y1 and San Juan County Road 162 to Utah <br />State Highway 46. <br />The facilities would consist of a waste rock dump, ore stockpile, ventilation holes, shop/change <br />room office trailer, water storage tank, buried water tank, and underground powder magazine. A <br />cargo van would provide storage for oil and mine equipment. Hazardous materials (such as oil, <br />diesel, etc.) stored on site would have secondary containment to contain a spill plus 25%. The <br />waste rock stockpile area would vary but is anticipated to be 50 by 100 feet the first year, I00 X <br />100 feet the second year and 100 X 150 feet the third year and 150 X 200 feet by the fourth year <br />to tenth year; each year it would gain height. There would be 40 to 60 tons of waste rock per <br />day. The ventilation holes (18 inches diameter) would be constructed as needed over the mine <br />life. All office and other buildings would be small mobile units located in the waste rock <br />disposal area. The Synthetic Precipitation Leaching Procedure required by the Colorado <br />Division of Minerals and Geology would stipulate the construction methods of the waste rock <br />and ore stockpiles. <br />The operator/claimant would comply with 43 CFR 3815.2, 3715.2-1 and 3715.5. The use or <br />occupancy of the lands in the report area is limited to that which is reasonably incident to mining <br />operations. The shop/change room/office trailer proposed for use on the mining claims is <br />associated with the mining operation and would be used for purposes that are reasonably incident <br />to mining. <br />The site would be reclaimed after the mine is closed. The mine portal would be gated suitable <br />for bat use and ventilation shafts would be sealed according to state specifications in <br />approximately 10 years. Reclaimed areas would be graded to blend with the topography, pocked <br />to retain water, covered with the stockpiled topsoil and reseeded. Maximum grade would not <br />exceed 3:1. The operator would post a reclamation bond sufficient to ensure reclamation of the <br />site in accordance with the mine plan. The applicant would be responsible to comply with all <br />Federal, state and local regulations. <br />Preferred Alternative (Applicants Mine Plan with BLM-added Mitigation Measures): <br />The Proposed Action has been modified to include the Best Management Practices (BMPs) listed <br />2 <br />
