- - III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspecton. Comments also describe any enforcementaclions taken during the inspection <br />and the facts or evidence supporting the enforcement action. . <br />plan. There was an even closer resemblance between the as-built contours and the pre- <br />mining contours, with the reconstruction of the drainage down the middle of the azea. <br />Field inspection, along with the comparison of the as-built map with the approved <br />reclamation contour map, showed that approximate original contour was achieved with <br />the backf liing and grading work. The reclaimed area blended in with the surrounding <br />undisturbed azea. The original drainage configuration was generally re-established on the <br />regraded areas oa both sides of East Roatcap Greek. There were no constnuted ditches <br />on the regraded azeas. There was no upland diversion ditch since the upland undisturbed <br />azea was heavily vegetated and, therefore, would not contribute significant runoff. All of <br />the runoff flows into the two sedimentation ponds. <br />On the west side of East Roatcap Creek, the drainage pattern slopes towazds the middle <br />of the regraded azea. It is in this middle zone where rills, a couple of inches deep, have <br />formed. The site was topsoiled, seeded and mulched in the fail of 2002 and some areas <br />have not greened up yet. If vegetation does not establish soon, alternate sediment bontrol <br />measures maybe needed to prevent gullying. No erosional gullies were observed outside <br />of this middle zone. The revegetation effort on the disturbed acreage will be monitored to <br />see if reseeding will be necessary. <br />Slope gradients were measured with an inclinometer during this inspection. Figure 1 is an <br />inclinometer transect location map and Table 1 shows the results of the measurements. <br />The measured slopes are in compliance with the approved post-mining slopes shown on <br />Sheet 9 of 10 of the Golder Associates report found in Volume 6A of the permit <br />application. <br />No signs of slope failure, such as cracks or slumping, were observed in the regraded azea. <br />There were no highwalls left at the site. <br />The original sedimentation pond at the bench site was reclaimed. Runoff from the graded <br />West Mine portal bench azea now drains to two new sedimentation ponds connected in <br />series. The two new sedimentation ponds were inspected and found to be in compliance. <br />The upper.pond was dry while the lower pond contained a little water, well below the <br />dischazge level of the primary tube. Both pond embanlanents were stable, although <br />vegetation has not takeri hold yet. The gated primary discharge valve of the upper pond <br />was open while that of the lower pond was closed, as designed. The riprapped emergency <br />spillway outslopes were intact. The inslopes of both ponds were stable but had no <br />vegetative cover yet. There aze no ditches or culverts at the West Mine portal bench <br />reclaimed area. All of the culverts were removed and salvaged. <br />4 <br />
