Specific hazards are discussed in <br /> specific mine asaessme-ats <br /> J This assessment evaluates the nine inactive or abandoned uranium <br /> minas on the Manti•L&Ial National Forest with the greatest potential to <br /> effect lands within oz near the Forest. Radioactive mine waste rock dumps <br /> are eroding from these mines and some of the mines are producing <br /> radioactive mine vata_s. Additionally, the sites may be visited by local <br /> 1- � residents or other pacple passing through the area. <br /> In 1989, a field inventory of all inactive or abandoned uranium <br /> •+ mines on the Manti-L&Oal National Forest was completed. The <br /> I purpose of the inventory was to collect data on safety and <br /> 7 environmental hazards and to rank the mines as to the relative <br /> r hazards. This inventory study was conducted in part by geologists <br /> from the Manti-LaSal National Forest and in part by Bio West, Inc. <br /> as a- contractor to the Manti•LaSul National Forest, Most of the <br /> field work was limited to qualitative observations and visual <br /> estimates of quantities. Spatial relationships were determined by <br /> i pace-and-compass and ucaled sketches. Radiation measurements <br /> were made using a calibrated Eberline scintilometer. <br /> The study produced individual site reports which described and rated <br /> potential public safety and environmental hazards. Forest geulogists <br /> evaluated and ranked the sites for potential CERCLA violations. The nine <br /> mines evaluated in tha following reports have the greatest potential to <br /> move radioactive substances into the hydrol--kic system. The inventory <br /> y <br /> i <br />
