<br />Trapper Bond Release Inspection <br />Colorado Division of Reclamation, Mining and Safety (DRMS) Permit: ID # C-1981-010 <br />Tuesday April 20, 2010 9:00 - 3:30 <br />Participants: <br />Rob Zuber, DRMS <br />Dan Hernandez;' DRMS <br />Jason Musick, DRMS <br />Jennifer Maiolo, Bureau of Land Management (BLM) <br />Lane Osborne, CO State Land Board <br />Graham Roberts, Trapper Mining Inc. (TMI) <br />Christine Belka, Office of Surface Mining Reclamation and Enforcement (OSM, Badge # 182) <br />Weather conditions: seasonally warm (60's), breezy, building cloud cover, light rain in afternoon <br />This was a Phase I bond release inspection for SL-11 at Trapper mine. The original bond release <br />application (to be revised as a result of this inspection) was for 64.4 acres in the Enfield, East <br />Flintlock (Z), and Flintlock pits. This reclamation was conducted in 2008. <br />Our inspection began at the southern end of the 50.2 acre bond release block designated F-AB- <br />08. This is the area's second growing season. Russian thistle is thick and giving way to Tumble <br />Mustard, which is the typical weed progression on new reclamation in this area. These species <br />should give way to grasses and shrubs in the coming years (vegetation to be evaluated at Phase II <br />release). The southern portion of the block appears stable - only one small rill was present. Mr. <br />Musick collected GPS elevation data to double check against the approved postmining <br />topography. <br />Walking north beyond the power line in F-AB-08 we encountered deeper rill erosion which <br />should be repaired. We discussed options for repairing the affected areas. Trapper has had good <br />results when placing brush in rills on other areas. The brush collects sediment during runoff <br />events and allows the channel to heal. Deeper rills / gullies may require more drastic repairs. <br />Rills and gullies extend between each of the permanent cross drain channels to the base of the <br />slope. Mr. Roberts indicated it may be a month or more before TMI is able to bring equipment <br />onto the area (due to ground conditions) and that he would likely grade in larger rills and brush <br />in the smaller ones. Block F-AB-08 should not be Phase I released until this work is completed <br />and the area is stable. <br />We proceeded to the 4.2 acre Z-AB-08 block. This area is steep and appears stable. Mr. Zuber <br />dug a hole to measure topsoil depth. TMI's permit indicates 10 - 14 inches of topsoil was to be <br />,placed. The topsoil measured about 16 inches. <br />Topsoil was measured again at the 2.6 acre Z-AB-08 block. The test hole revealed 14 inches, still <br />on the upper end of the topsoil depth indicated in the permit. The 1 acre block of Z-AB-09 also <br />showed greater than 14 inches of topsoil. <br />E-AB-08 is split into two sections: one 4.9 and one 1.2 acres. Both blocks show significant
