Liberty Mining, LLC <br />DRMS 110 -d Permit Application <br />October 2013 <br />Reclamation of the Declines <br />The decline portals will be closed after all necessary materials have been placed into the <br />declines (ore pad liner, waste rock, ore stockpile pad, etc.), and backfilled with waste rock, <br />slightly mounded to prevent ponding of surface water and infiltration into the underground mine. <br />The area will then be graded and seeded in accordance with the re- vegetation plan. <br />U (7) Facilities Evaluation <br />The engineer designed stormwater management plan captures on -site water and prevents off <br />site migration. The plan also diverts off site water from entering the site, minimizing the amount <br />of water to be managed. This plan is designed to mitigate environmental hazards associated <br />with uranium mining. <br />Mined uranium will be placed on the engineer designed ore stockpile pad. The ore stockpile <br />pad is designed to capture uranium and uranium impacted stormwater within the boundary of <br />the pad and to collect the water in a lined containment sump to prevent leaching. The pad will <br />be constructed of concrete to prevent uranium impacted stormwater infiltration. The pad will <br />drain to an HDPE lined sump pond to collect uranium sediments from the ore stockpile and <br />contain the water until it can be pumped to the underground workings for support of mining <br />activities. The sediments will periodically be removed from the pond and hauled to the mill for <br />processing. <br />Material containing uranium that is extracted from the mine will be transported off site for <br />processing. All processing by- products will be handled and disposed of by the milling facility; <br />there will be no by- products on the Liberty Mine site. Stormwater will be contained on site and, <br />when possible, used to support underground mine workings or used for dust control on the mine <br />surface and access roads. <br />The surface of the Liberty Mine has a relatively elevated background gamma radiation level due <br />to previous uranium mining activities, subsequently reclaimed. The average background <br />reading for the site is 120 counts per minute. The background reading was established during a <br />baseline gamma survey in October 2012, using a calibrated Ludlum Model 3 gamma radiation <br />detector on a fifty -foot surveyed grid on the surface of the mine and surrounding area. The <br />readings were taken with a Model 44 "pancake" detector attachment, approximately 3 inches <br />from the ground surface. The results of the gamma survey can be found on the Baseline <br />Gamma Radiation Study maps. <br />U (7.d) Sampling Program <br />The Liberty Mine site is designed to contain or divert all run -on stormwater before it comes in <br />contact with the mining operations pad. Stormwater that falls directly on the operations pad will <br />be captured and contained onsite. Following Stonrwater Management Plan (SWMP) <br />guidelines, BMPs are included in the design of the mining operations plan to minimize discharge <br />of pollutants in areas that are off the mining operations pad. The structures will be inspected <br />and monitored in accordance with the SWMP. Should a discovery of a stormwater discharge <br />occur, the plan will be altered to include a monitoring station and sampling frequency. <br />Liberty Mining, LLC Moab, Utah SMA Ref. 5821897 Page 58 <br />
