compliance and groundwater sampling will be implemented on Three Bells Property and <br /> hydrologically downstream as appropriate and required by the Board. <br /> MODFlow models and analyses have been created and run to demonstrate the anticipated <br /> effect of reclamation on existing groundwater resources. Models were created to estimate the <br /> effect of lined reservoirs in the reclaimed mine site on groundwater conditions and flow. <br /> Results from MODFlow modeling are available in Attachment C. <br /> 5.5.6 Topsoiling <br /> Overburden has been stripped from mined areas and stockpiled close to the Cache la Poudre <br /> River for use in reclamation. Stockpile locations are away from daily operations and require <br /> minimal disturbance, as per the Rules. Placement of overburden will be done is such a <br /> manner so as to create a relatively uniform layer of topsoil, ranging in thickness from 3-12". <br /> Stability of any replaced topsoil will be of importance as any areas to be backfilled are <br /> planned to be used for housing development. <br /> Noxious weed control and removal will occur on an as-needed basis to prevent spread of <br /> noxious or invasive weeds. <br /> No historic structures are located on Three Bells Mine. <br /> A statement regarding the permit amendment with the Three Bells Mine permit number shall <br /> be posted at the entrance to the facility. A fence surrounds the affected area to mark the mine <br /> and Affected Area boundary, according to Paragraph 3.1.12(2)(b). <br /> MMM will notify DRMS of any toxic or hazardous spills which occur on Three Bells <br /> Property. MMM will contain and remediate any spills which do occur, as appropriate, on an <br /> individual case basis. <br /> GEI Consultants,Inc. 18 June 2014 <br /> Three Bells Mine Reclamation Permit Amendment <br />
