Mr. Travis Marshall <br />March 6, 2014 <br />Page 3 <br />distributed over the area of disturbance and that soil will be imported if additional <br />growth medium is required. Liberty commits herein that topsoil will be spread over <br />the waste rock and overburden stockpiles to the extent that the minimal site topsoil <br />reserves allow. <br />Exhibit E <br />13. Rule 6.2.1(2)(b) requires that maps be signed by the map maker. Engineered <br />designs are considered preliminary, not for construction, and therefore are not <br />stamped by the Professional Engineer. Upon issuance of the mining permit, the <br />designs will be finalized, with construction details, reviewed, and signed and <br />stamped by the Colorado Registered Professional Engineer, ready for construction. <br />Such designs will be submitted to DRMS for final approval before any construction <br />begins. <br />14. Sheet EX.E.2.1 attached in Appendix B Figures, is a map which illustrates off site <br />topography to a distance of 300 feet outside of the proposed permit area. The map is <br />comprised of the Mining Plan Site Plan overlaid upon the USGS 7.5 Minute map of <br />the location. This map illustrates the relationship of the proposed mining area to <br />adjacent land. <br />15. Rules 6.3.5(3)(d) and 6.3.5(e) require statement of average overburden and topsoil <br />thickness, respectively. The proposed average thicknesses of overburden and <br />topsoil to be placed during reclamation are depicted on Sheet EX -E.3.1 attached in <br />Appendix B, Figures. Those are 4 to 6 inches of topsoil placed over an average <br />thickness of 2.4 feet of overburden and waste rock. <br />Exhibit U <br />16. Liberty herein commits to submitting engineered as -built designs for the ore pad. <br />This commitment involves a site visit by qualified professional, preparation of the <br />figures in CADD, and professional engineer review and certification. <br />17. The proposed dimensions of the waste rock pile are 263 feet by 73 feet by an <br />estimated 10 feet as shown on Sheet EX -E.2.1 in Appendix B, Figures. <br />18. Please see Appendix D for documentation of the lack of acid forming conditions at <br />the proposed Liberty Mine including geochemical analysis of the waste rock and ore. <br />19. Water rights — Liberty is currently researching the availability of water rights for the <br />mine and commits to securing the rights prior to operating the mine. <br />20. Rule 6.4.21(7)(e) - The designated chemicals of concern on the site are the uranium <br />ore itself, small quantities of petroleum fuel and lubricants for equipment, and <br />blasting agents. The uranium ore will be stored in the ore pad near the mine portal <br />area. There are three levels of control to prevent releases of these chemicals. The <br />primary controls are the concrete ore pad structure and the lined pond to contain ore <br />pad drainage. Both of these structures are located in the mine portal area. The <br />secondary control is the contouring of the mine portal area to prevent run off. The <br />
