Cottony <br />743 Horizon Court, Suite 330 Division Dlrettor <br />Grand Junction, Colorado 81506 Natural Resource Trustee <br />RE: Logan Wash, Permit No. M-1977-424,,/Te%hnical Revision No. 4 Preliminary Adequacy Review ~ <br />Dear Mr. Smith: <br />DMG completed the preliminary adequacy review of your application for Technical Revision No. 4 (TR-04) to <br />permit no. M-1977-424 for the Logan Wash mine site. The application cannot be approved until the following <br />issues are adequately addressed. Please submit a response to the following issues as soon as possible, but no <br />later than 12:00 Noon on March 29, 2004 so the decision due date set for 4:00 p.m. March 29, 2004 can be met. <br />If you cannot respond by 12:00 Noon on March 29, 2004 please submit a written request for extension of the <br />decision date. If your response, or an extension request, are not received by 12:00 Noon on March 29, 2004 this <br />application may be denied. <br />ADEQUACY ISSUES <br />1. Please specify what the final disposition of the road berms will be. The current reclamation plan <br />indicates these berms will be removed and used as topsoil material for site reclamation. <br />2. TR-4 indicates that loose metal banding, used to hold the chain link rock fall protection, was <br />removed and disposed of. Please verify that all banding was removed. <br />3. TR-4 did not include the revised proposed seed mix referred to as Table 1. Please submit this table. <br />Also, please submit revised proposed shrub tubling transplant details (planting densities, species <br />and general locations). <br />4. Please verify that backing up water in the research mine, to the levels proposed, will not result in <br />transmission of water to the L1 portal. The maps iri DMG files are not adequate to make this <br />determination. If transmission of water to these lower workings is possible, please demonstrate that <br />the French drain in these workings will be adequate to handle any additional flows, or demonstrate <br />that the water will not adversely affect stability of that plug. <br />5. Please submit any documentation available demonstrating the work completed inside the research <br />portal prior to sealing (shotcrete application, coffer dam foundation prep, collars on the discharge <br />pipe to prevent piping, etc.). <br />6. A geotechnical evaluation of the portal closures, specifically the research mine, is forthcoming from <br />our Denver office later this week. <br />Office of - Office of Colorado <br />
