loose cover over the areas having surficial uranium concentrations above 500 ppm. <br /> Truck counts will be recorded to allow for approximating the volume of cover <br /> material placed on the stockpile. <br /> 10.During grading, verify that the cover is a minimum of 12-inches thick and has <br /> average uranium concentrations of less than 500 ppm using a tape measure and <br /> XRF analyzer. Record these measurements for each grid location. Any cover <br /> material exceeding an average uranium concentration of 500 ppm is to be removed <br /> and placed in an area to be covered. <br /> 11.Upon conclusion of the cover placement, reinstall the safety berms using <br /> development rock and reinstall any drainage channels that were temporarily <br /> removed. Verify that these berms and channels have uranium concentrations less <br /> than 500 ppm using XRF analyses. <br /> 12.Upon conclusion of the construction activities, prepare and submit a report to DRMS <br /> and BLM that summarizes the construction activities. This compliance report should <br /> include: (a) a figure and table showing the location and uranium concentrations of <br /> the surveyed grids; (b) a figure showing the location of the earthen cover, (c) an <br /> estimate of the volume of cover material placed based on truck counts; and (d) a <br /> table listing the cover thickness and uranium concentration measured in each grid. <br /> Section 6.2.2 (Evaluation of the Proposed Sunday Low-Grade Stockpile Cover <br /> Design: Upon conclusion of the construction work, safety berms and stormwater control <br /> systems will be reestablished to minimize erosion from surface water runoff during <br /> precipitation events. The 12 to 18-inches of development rock cover over the areas of <br /> the Low-Grade Stockpile will prevent windblown erosion of higher-grade material <br /> exceeding 500 ppm uranium and prevent adverse off-site impacts during periods of <br /> temporary cessation. The development rock cover may also be part of a final closure <br /> design in the event that the low-grade stockpile cannot be shipped off-site for <br /> processing. <br /> 10 <br />
