Larsen Colorado, L.L.C, has reviewed the comment letters attached to your <br />correspondence and has no comment ar contest, <br />7. Larsen Colorado, L.L.C. will comply with the DBMS policies regarding the storage <br />of all petroleum and or other hazardous materials at the site. Larsen Colorado L.L.C. <br />will store the fuel lubricants and other products in a fuel storage mounted on a <br />Department of traasportation trailer with a containment as required by DBMS. <br />$. Larsen Colorado, L.L.C. anticipates stockpiling approximately 30,000 tons or 20,000 <br />cubic yard of coastruction material on the site <br />9. Larsen Colorado, L.L.C, anticipates stockpiling 20,000 tons or 13,500 cubic yards of <br />topsoil on the site. <br />10. Larsen Colorado, L.L.C, provided the reclamation maps signed by a registered land <br />surveyor during the site visit of June 4, 2007 <br />I I. The pinch point will be mitigated to be a smooth. round transition while erosion <br />protection such as check dams will be installed to prevent erosion in this area. In <br />addition during this time frame of mining, with the approval of the DBMS, we expect to <br />proceed with Phase II of the mine, eliminating this pinch point. <br />12, The area highlighted is not in the mining plea and therefore will not require <br />reclamation or re-vegetation. <br />13. Please see the enclosed drill log for the well located on the site. The static water <br />elevation is 130 feet below the well head which is at 6180. Therefore the static ground <br />water elevatioa is approximately 6050. The Mine Plan allows for mining to an elevation <br />of 6100. Based on this information the static ground water elevation is 50 feat below the <br />lowest mining elevation ensuring that ground water will not be encountered during the <br />mining process. <br />14, Larsen Colorado, L.L.C. is aware of the CDPS Stormwater Permit and the NPDES <br />Permit requirements. Larsen Colorado, L.L.C. will comply with the guidelines <br />established by theses permits as they apply to the Byzantine Quarries. <br />I5. Larsen Colorado, L.L,C. has reviewed the Geotechnical Stability Exhibit <br />Memorandum from Allen C. Sorenson. Larsen Colorado, L.L.C. will complete a <br />geotechnical report with the annual reclamation report providing updated geotechnical <br />observations, measurements and associated recommendations for quarry development to <br />provide a safe highwall at the time of reclamation.. In addition Larsen Colorado, L.L.C. <br />will prepare "a blasting report for each shot' and retain these documents for a minimum <br />of three years. <br />
