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 inspection <br />and the facts or evidence supporting the enforcement action. <br />This was a partial inspection conducted by Tom Kaldenbach and David Berry of the Colorado Division <br />of Minerals and Geology. Forrest Luke represented the operator. The ground was dry. <br />AVAILABILITY OF RECORDS <br />Trapper Mine has the following six documents available to the public at the Moffat County Courthouse <br />Blasting Schedule for time period 3/97 - 2/98, TR-71, TR-77, RN3/PR-4, Phases I & II Bond Release <br />dated 9/96, and the 1996 Annual Report. <br />ROADS AND HYDROLOGIC BALANCE <br />Roads, Ditches, and Culverts <br />The following roads, their embankments, and adjacent ditches appear to be constructed to design and <br />are in good repair: A Haul Road, those segments of North A Road, Mid A Road, and Life of Mine <br />Road which are between Ashmore pit and the ash dump, the access road on the east side of the ash <br />dump, Ash Haul Road, D Road, and New #1 D Road. <br />The light duty road that extends from North A Road to East Pyeatt #1 pond has a gully across it more <br />than 1 foot deep near the junction of the two roads where a ditch crosses the access road. The ditch <br />is also downcutting uphill from the crossing. This gullying appears to have contributed to the sediment <br />filling the East Pyeatt #1 pond a short distance downhill. Repair of this erosion is recommended in <br />order to minimize erosion. The operator says it will repair the gully soon when equipment is brought in <br />to clean out East Pyeatt #1 pond. <br />Culvert A-12 contains 8-12 inches of sediment; it is functional but should be maintained to ensure <br />continued function. <br />Culvert A-8 is on Map 51, Sheet 2 but could not be found in the field. Operator will research <br />Sedimentation Ponds and Dozer Basins <br />East Pyeatt Drainage - All three ponds are discharging through their principal spillways. The inslopes <br />and embankments of these three ponds are well-vegetated and appear stable. The #1 pond is full of <br />sediment and will be cleaned before October according to the operator. The dozer basin at the inlet of <br />the A-5 double-culvert is full of water. Inflow is 5-10 gpm of clear water from pumping of Ashmore pit. <br />Middle Pyeatt Drainage -Only the #1 pond contains water (approximately 2 feet deep). The inslopes <br />and embankments of the three ponds are well-vegetated and stable. <br />West Pyeatt Drainage -The #2 pond contains 1 foot of water and its inslopes and embankments are <br />well-vegetated. <br />Johnson Drainage - #9 and #10R ponds are discharging a trickle of clear water through their flumes; <br />the inslopes and impoundments are well-vegetated and appear stable. <br />Monitoring wells <br />The monitoring well located below the Middle Pyeatt #3 pond needs a cap put on its casinghead. <br />-3- <br />
