III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations <br />made during the inspection. Comments in Section IV describe any enforcement actions <br />taken during the inspection and the facts or evidence supporting the enforcement action. <br />PROCESS WASTE Process wastes was disposed of in the Mine Waste Disposal Area. The waste fill <br />area was found to be in good repair, stable, with no slide cr erosion features (see Photographs <br />202gm and 213g). <br />SUPPORT FACILITIES Permanent water treatment facilities of the approved post mining land use <br />of developed water resources were inspected. Features include the access road across the <br />reclaimed Portal 1 facilities area (see Roads above), the mine drain access tunnel (culvert, <br />Photograph 218gm), the bridge across North Thompson Creek to Portal 1, the mine drainage <br />carrier pipe (hanging from the bridge), the alternate drain support beam, water monitoring <br />well M-3 (Photograph 206g), the mine drainage piping (Photograph 216g), the Long Pond <br />(Photograph 127g), Treatment Ponds T-1 and T-2, Sedimentation Pond P-9, and the discharge <br />piping (Photograph 212g), and the associated surface areas. All of these features were in <br />good repair, less the bridge. As was the upper bridge, this bridge is in (permitted) disrepair, <br />satisfactory only for foot traffic to cross for inspection of the immediate Portal 1 area. <br />REVEGETATION Although dry, vegetation looked good on the reclaimed areas. Revegetated <br />areas of the permit area to the north of and contiguous to North Thompson Creek appeared <br />to have been lightly grazed. There were no signs of gully erosion. Photographs of revegetation <br />include 198gm of the Middle Thompson Creek Air Portal (note change in grass species just to <br />the left of the bush), 201 gm of the Stony Ridge Air Shaft (note change in grass species in the <br />center of the photograph below the rock outcrop), 202gm and 213g of the reclaimed Mine <br />Waste Disposal Area, 203gm and 203gm2 of the Portal 1 facilities area, 204g of the Portal 3 <br />area, 205g of the New Fan Shaft area, 206g and 2088 of roads in the Portal 3 area, and 218gm <br />of the Portal 1 area. Photograph 220g is of the steep portion of the conveyor corridor from the <br />turn-around (out-load pad) to Garfield County Road 109. Photograph 221g is of the conveyor <br />corridor across the lower river terrace to the Roaring Fork River. <br />SUBSIDENCE No subsidence feature was noted during the inspection. <br />RELCAMATION SUCCESS Reclamation of disturbed areas appears to be successful. Areas of <br />backfill are stable. The areas have been properly graded. Vegetation appears to have been <br />well established. The mine waste disposal site appears to be stable and well vegetated. The <br />mine drainage system was in good repair and operating properly. The bases of four water <br />monitoring flumes still need to be removed. <br />C-81 -025, Page ~ of ~~/ Pages, (date) ~ Lb,.
