~ ~ 1.0 PHASE I BOND RELEASE • This application for Phase I bond release of applicable Trapper Mine lands is submitted in accordance with the Colorado Division of Minerals and Geology (DMG) Guideline Regarding Selected Coal Mine Bond Release Issues of April 18, 1995. Wi[h this submittal, Trapper is prcrposing to release 2,511.7 acres of land from Phase I bond liability as outlined on Map 1.0. This includr:s all lands that have been regraded, wtth drainages reestablished, in accordance with Trapper's approved permit document (C-81- 010) from the beginning of mining through the end of 1995, wtth the exception of 72.0 acres of reclaimed land near the north end of the East Pyeatl watershed. This acreage, encompassing parcel A-C-94 and those portions of parcels A-C-95 and A-B-95 located west of the Middle A Haulroad (Map 2.0), was removed from the Phase I bond release application because of concerns about the current stabiltty of the main stem reconsiruded drainage. While Map 1.0 breaks out major watershed boundaries, the single block proposed for bond release encompasses all recoMoured watersheds as outlined. Map 2.0 delineates all reclaimed parcels that are included within this Phase I bond release block. 1.1 Post-mining Topography Demonstration Map 1.0 provides as-built post-mining topography contours for all Trapper Mine lands regraded through 1995. The map was constructed from aerial photogrammetry data collected in November 1995. In addttion, certified representative cross-sections comparing as-built topography with the approved permtt map (M-12) a2 presented on Map 1.1. Cross-section locations are given on Map 1.0. The Map 1.1 cross-sections compare onty projected PR-03 (1992-1995) contours approved on M-12 permit maps against as-built topography map contours. This is because of an understanding reached between DMG and Trapper that pre-1992 approximate original contour (AOC) was approved with the approval of the PR-03 document (refer to letter from Joseph Dudash to Forrest Luke dated April 4, 1996). The Map 1.1 cross-sections demonstrate that as-built contours for 1992-1995 are very close to contours given in Map M-12, indicating that AOC requirements have been achieved. 1.2 Drainage Reestablishment Documentation As explained in Section 1.1 for topographic cross-sections, drainage profiles are likewise submitted only _ for drainages reestablished during the PR-03 years 1992-1995. Profiles comparing as-built drainage elevations against approved permit drainage elevations (from Map M-12) are presented on Map 1.2. Profile locations are shown on Map 1.0. These profiles demonstrate that drainages have been reestablished according to the approved permtt plan. 1-1 -~~BmirrnL Dlf~~~ )z~as~q']
