Colorado Rose Red, Inc. Page 7 <br /> Colorado Rose Red Granite Quarry M-1978-332 <br /> Ground Engineering has been contacted and will not do that evaluation. Colorado Rose Red is in <br /> the process of finding someone that can address it but due to the financial state of the company it <br /> is proving impossible to find someone that will take the job on. We propose limiting the mines <br /> operation to no blasting or above ground quarrying until this can be addressed. At the current time <br /> Colorado Rose Red will not start the quarry operations until it has the proper county permits for a <br /> rock quarry have been obtained and those are on hold. They can, under the existing land use <br /> status continue to removed underground stone and remove the stone in the Spill areas without <br /> blasting. Processing can be done in the plant site area until the spill areas have been cleaned up. <br /> Colorado Rose Red will commit to filing a Technical Revision to address the structural stability for <br /> the new quarry highwalls prior to commencing blasting and mining on the surface quarry area. <br /> Adeq 2 <br /> Rule 6.5—Geotechnical Stability Exhibit <br /> 1. As part of the additional information provided with GE's Report, it appears that Colorado <br /> Rose Red Granite Quarry is applying to blast within the quarry. It also appears that GE's <br /> slope stability evaluation does not consider dynamic loading in the Report. Please have GE <br /> reevaluate slope stability to include dynamic loading in which it may experience in the <br /> event of blasting. <br /> Ground Engineering has been contacted and will not do that evaluation. We propose limiting the <br /> mines operations to no blasting or above ground quarrying until this can be addressed and filing a <br /> Technical Revision for approval prior to commencing these activities. <br /> 2. References to a GE report dated August 29, 2017 have been observed throughout the <br /> Report. Please provide this August 29, 2017 document as it appears to provide additional <br /> information regarding values used within the Report. <br /> A copy of this report was filed with the Division on March 22, 2018 <br /> 3. Within the Report, only the results of the stability analysis have been provided. Please <br /> submit the model associated with each joint orientation analyzed in the Report. <br /> As noted before Ground Engineering will not provide additional information for their study. We <br /> have no way to generate the model used, or provide it as requested. <br /> Additional Information. <br /> Attached is the Proof of Publication for the Public Notice and a copy of the adjoining owners Notice mailing <br /> receipt card. <br /> These responses addressed the adequacy questions you have <br /> that we are able to address at this time . I will place a copy of <br /> this packet with the Larimer County Clerks office as required and <br /> proved proof of placement .
