This was a complete inspection of the Carbon Junction Mine conducted by Tom Kaldenbach of DRMS. Mike Savage represented the operator during the inspection. A contractor was performing earthwork on the coal mine site during the inspection. Photos taken during the inspection are attached to the end of this report. The ground was dry. A Phase I bond release application(SL-03)covering much of the site is in review. A bond release inspection was held in November 2006. Availability of Records All required records were on file at the office of Goff Engineering (see attached list). Signs and Markers Permit boundary markers were properly displayed at the numerous locations inspected. Topsoil markers were properly displayed on the only remaining stockpiles: 4, 7, and 8). The mine i.d. sign was properly displayed on the only public road entrance into the permit area. Roads The asphalt-surfaced main haul road was in good condition. The main haul road and the North Pit haul road have previously been approved for permanent retention,as documented in Appendix 5-1 of the permit application. The width of the North Pit haul road has been reduced to 30 feet as specified on page 5-26 of the approved reclamation plan. The road surface of the North Pit haul road was in good condition during the inspection. Hydrologic Balance Drainage routing. Pond 1 (the large pond) receives runoff from the coal permit area and gravel permit area. The following four parts of the coal permit area drain to Pond 1: the north half of the North Pit reclaimed slope,the east half of the PRSA,the South Pit Drill Pad,and the Equipment Yard. Runoff from the west half of the PRSA reports to Pond 2. Runoff from the south half of the North Pit passes through a grass filter terrace at the base of the reclaimed slope and then flows to the newly constructed Carbon Junction channel via the ditch next to the North Pit Haul Road. The south half of the North Pit reclaimed slope was approved as a small area exemption in TR-14. No water was flowing on the site during this inspection. Positive drainage appeared to exist throughout the drainage route from backfilled areas to the ponds. The dual culverts that had extended underneath the access road on the north end of topsoil stockpile 7 have been removed leaving a continuous triangular ditch approximately 10 ft.wide and 3 feet deep,with 3:1 sideslopes(see photo at end of this report). The culverts and overlying asphalt roadway were removed 3
