III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. This was a complete inspection of the Carbon Junction Mine conducted by Tom Kaldenbach of DRMS. No one else was present. The entrance gate was locked. The site was dry. Phase I reclamation liability(backfilling,grading,and drainage re-establishment)remains for the following areas: topsoil stockpiles 4,7,and 8;the two sediment control ponds(1 and 2);various ditches;and various boreholes. Phase I reclamation liability also remains for removal of equipment from the Equipment Yard. Phase II and III reclamation liability(topsoiling and revegetation) remains on all disturbed areas. Selected photographs taken during the inspection are provided at the end of this report. 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. 3
