Rimrock Exploration & Development, Inc. <br />J-Bird Uranium Mine/ DMO/ EPP Designated Chemical(s) and Material(s) Handling <br />6.0 DESIGNATED CHEMICAL(S) AND MATERIAL(S) HANDLING <br />As previously mentioned, Rimrock has a developed a SWMP in accordance with CDPHE <br />CDPS General Permit. The SWMP was prepared as a means by which to identify <br />protective management practices for the Mine and prevent unauthorized release of <br />pollutants to the environment. <br />6.1 HANDLING OF HB-08-1161 DEFINED MATERIAL <br />The environment will be protected from ore stockpile material by the construction of an <br />ore pad adhering to DRMS General Ore Pad Construction Criteria. When the ore- <br />stockpile accumulates to an approximated volume, the material will be loaded onto haul <br />trucks and transported off-site to a mill for processing. The waste rock pile(s) do not <br />exhibit any DMO defined criteria (refer to Sections 5 and 14). However, as stoped areas <br />develop, this material will be returned underground, making available more surface area <br />as underground mining continues. Waste rock dumps will remain on surface when mine <br />life exhausts. A post-mining Radiation Monitoring Plan will be initiated to compare with <br />pre-mining activity levels (see Section 19.0 and Attachment H). These dumps will be <br />contoured to match existing topography, covered with topsoil and reseeded (see Section <br />17.0). The SWMP will be maintained until the site has been fully reclaimed to assure that <br />stability of the reclaimed dump sites is monitored. Additional information can be <br />obtained by referencing the SWMP which details designed Structural Best Management <br />Practices (BMP). <br />6.2 HANDLING OF "DESIGNATED CHEMICALS" <br />There will be no metallurgical process associated with the Mine. Disposal of petroleum <br />products will not occur on-site. A mobile Rimrock maintenance vehicle will handle all <br />regular maintenance and used products will be removed from the Mine site. Refer to <br />SWMP Section 3.3.2 for detailed discussion of Non-Structural BMP's, Housekeeping <br />Spill Prevention and Response, Exposure Minimization, Other Controls and Site <br />Maintenance. <br />12
