III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the <br />inspection and the facts or evidence supporting the enforcement action. <br />This was a complete inspection of a revoked mine. The focus of this inspection was to evaluate <br />the status of the reclamation in terms of potential impacts to the local environment and/or public <br />health and safety. Weather was clear and ground conditions were dry. <br />The Twin Pines Mine was reclaimed by Twin Pines Investment Ltd. in 1995. The permit was <br />revoked and the bond forfeited in May, 1996. The Division currently holds S22,600 in forfeited <br />bond funds. <br />MINE AREA <br />Access to the site is via a Fremont County road, which ends at the former mine site. Agate <br />across the road at the Oak Creek crossing is currently locked, prohibiting vehicular access. A <br />mine identification sign, permit boundary markers, and an MSHA refuse pile sign remain in place. <br />The mine site consists of approximately 7.6 acres of reclaimed land, Mine entries, which were <br />developed in a pre-SMCRA highwall, were sealed and backfilled. The lower portion of the <br />highwall was backfilled when the portals were reclaimed. The fill covering the portals appears <br />stable. Vegetation is becoming established on the fill. There are no signs of movement or <br />settling in the fill. <br />There is a bench just above the portal fill material which is approximately 30 feet wide. The <br />remainder of the pre-SMCRA high wall stands above this bench. The highwall is approximately <br />40 feet high and consists of interbedded sandstones and shales. There are several fractures in <br />the wall, with exposed angular blocks ranging from 1 to 5 feet in width. Some of these <br />boulders have spalled off the face of the wall onto the upper bench in the past. It does not <br />appear that any rocks have fallen during the past few years. This highwall has not changed <br />visibly during the past eight years, since this inspector first visited the site. <br />Any rocks which fall of the wall should be contained on the bench, due to its width and the <br />earth berm on the outside edge of the bench. Access to the bench is blocked by a barbed wire <br />fence. Signs hanging on the fence read, "Danger-Falling Material". Access to the top of the <br />highwall from the south can only be gained by hiking over remote and rugged terrain. <br />There is a sediment pond on the lower mine bench. The pond is incised into the bench. Slopes <br />inside the pond are gradual enough to allow for ingress and egress by cattle. There is a <br />functional CMP spillway which discharges water from the pond into Lewis Gulch, downhill from <br />the mine access road at a concrete flume. Approximately 1500 cubic yards of earth are stored <br />near the pond. This material will be used to backfill the pond when it is no longer needed. The <br />pond was dry at the time of this inspection. There are no signs of instability with the pond. <br />
