Lewicki <br />Director - Engineering Services <br />Panorama Resource Services, Inc. <br />1675 Latimer Street, Suite 750 <br />Denver, Colorado 80202 <br />Re: Trinidad Basin Mine Partial Bond Release Request (our File No. C-048-81) <br />Dear Mr. Lewicki: <br />The Division has recently completed a review of the TBM partial bond release <br />request. Below is a list of concerns which need to be addressed by the <br />permittee so that the Divisian may fully evaluate the request. <br />1. The public notice published August 12, 19, 26, and September 3, 1985 <br />contains the incorrect total bond figure of $327,000.00. The correct total <br />bond is $330,000.00. A corrected public notice will need to be republished. <br />2. A post-mining topographic map should be included with the bond release <br />request. This map should contain such information as stream channels, <br />properly labeled cross-section locations, and locations of permanent ponds and <br />roads, if any. This map needs to be certified by a registered professional <br />engineer. <br />3. Five cross-sections, drawn on graph paper, are presented. These <br />cross-sections represent the post-mining topography at various locations in <br />the mine. Each cross-section should be keyed to the map discussed in comment <br />No. 2. Furthermore, each cross-section should be drafted with vertical and <br />horizontal scales given. The exact boundaries between undisturbed and <br />reclaimed lands should be labeled, as well as ditches, roads and other <br />pertinent features. Each cross-section should be certified by a registered <br />professional engineer. <br />4. What is the final width of the road to Pit No. 1? This road, drawn to <br />scale, should be included on the previously discussed topographic map. <br />5. The Pit No. 4 road was not approved to be left. This change was termed <br />insignificant, with full bond release requested for this area. The Division <br />has not approved leaving this road unreclaimed. In order to do so, a permit <br />revision will be required. <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203 Tel. (303) 866-3567 <br />
