Liberty Mining, LLC <br />DRMS 110 -d Permit Application <br />October 2013 <br />Similarly, should the presence of groundwater in the two monitoring wells be detected, a <br />sampling program and schedule will be activated. Currently, the monitoring wells are under <br />quarterly monitoring. One quarter of monitoring has revealed no detectable water in either of <br />the two wells. <br />U (7.e) Human Health Considerations and Monitoring <br />In areas where mine workers congregate regularly (i.e. lunch /wash rooms, storage facilities, <br />office trailer), the air quality must be monitored at a minimum of every two weeks. If the <br />monitoring reveals that radioactivity is elevated above the threshold limits, the area must be <br />ventilated and monitored once a week until five consecutive readings determine that the levels <br />are below the threshold limits. <br />During underground operations, mine workers are to follow all MSHA safety regulations in <br />regards to general underground mine safety and uranium radiation exposure. <br />U (8) Groundwater Information <br />Based on current and historical exploration drilling and the construction of two groundwater <br />monitoring wells, substantial groundwater is not present at the Liberty Mine site from the ground <br />surface to a maximum depth of 580 feet below ground surface. The geologic setting of the mine <br />site is not favorable to the presence of groundwater because of limited recharge and the <br />presence of interbedded, low permeability siltstones and mudstones. <br />U (9) Groundwater Quality Data <br />No groundwater was encountered during exploration drilling and during the installation of two <br />groundwater monitoring wells. The groundwater monitoring wells are to be monitored every <br />quarter for the next five successive quarters. Any indication of groundwater will be reported to <br />the Division and all other interested parties. <br />Upon the presence of retrievable groundwater, the water will be sampled according to USEPA <br />SW 846 and submitted to a laboratory and sampled for the following parameters: <br />Metals: Sb, As, Ba, Be, Cd, Cr, Pb, Hg, Mo, Ni, Se, Ag, TI, U, V, Al, B, Co, Li, Ca, Cu, Fe, Mn, <br />Zn <br />Hardness <br />Fluoride <br />Nitrate, Nitrite, Nitrate /Nitrite <br />Chloride <br />Sulfate <br />Total Phosphorus <br />Carbonate, Bicarbonate, Alkalinity <br />pH <br />Specific Conductance <br />Total Dissolved Solids <br />Gross Alpha /Beta and Total Solids <br />Liberty Mining, LLC Moat), Utah SMA Ref. 5821897 Page 59 <br />
