The application cannot be approved until the following issues are adequately addressed. Please submit a response to the following issues as soon as possible, but no later than March 29, 2006 so the decision due date set for April 9, 2006 can be met. If you cannot respond by March 29, 2006 please submit a written request for extension of the decision date. If your response, or an extension request, are not received by March 29, 2006 this application may be denied. ADEQUACY ISSUES Exhibit C -Pre-mining and Mining Plan Maps 1. Please verify that Exhibit C maps show all utilities as required by Rule 6.4.3 (b). 2. Please verify that Exhibit C maps clearly identify the proposed affected area boundary and the proposed excavation area boundary as required by Rule 6.4.3 (d). Currently, the area west of the 110c permit boundary, that has been affected by mining, does not have a clear affected area (or unit) boundary around it. 3. The map shows Unit 11 as all area within the permit boundary that is not designated by the other phases. This extensive area identified as affected area results in several permanent manmade structures, including utilities, within 200 feet that have not been properly identified per Rule 6.4.3 (b). Please revise the application accordingly. Please show and label the location of topsoil/overburden stockpiles. The site has far more overburden than originally reported. Please ensure adequate storage for this material is allotted to stockpile locations on the map. 5. Please show the proposed sediment control features for the mining phase on the corresponding map and document that they are adequately sized and constructed to handle anticipated stormwater flows.. 6. The December 12, 2005 inspection of this site noted an overburden pile extending down the drainage and outside the 110c permit boundary at the corner on the south side of Unit 5. The proposed affected area boundary in the 112c conversion application does include this area in Unit Office of Office of Colorado Mined Land Reclamation Active and Inactive Mines Geological Survey
