r ~ • <br />i <br />2 <br />* Game Fence: Fencing remains rolled on-site, down-slope from the dam crest. Fresh sign <br />indicates numerous deer in the area at this time. Since pond water has not yet frozen, it is <br />probable that the pond is being used as a water source by these animals. <br />Trailer Area Berm: Re-berming of the slope just south of the former trailer parking area has <br />been accomplished; the berm does not appear to have been compacted. <br />Hazel A Portal Backfill: It was impossible to verity completion of the required fifteen-foot <br />horizontal backfill of the Hazel A adit around the 36" CMP, due to the locked access. There <br />was no discernable change in the outer face of the emplacement since the inspection, other than <br />some sift-in of soils in front of the door. Since there has been no compaction of back-till, <br />substantial settling and outwash can he expected during the Spring meltoff. <br />Coffer Dam and Pum -B~ystem: Due to the blocked access noted above, it was impossible <br />to ascertain status of this system, or water levels behind the bulkhead in the Hazel A. There <br />was no audible evidence of pump activity at the time of our survey; water could be heard <br />dripping into one or more pools beyond sight at the adit entrance. There was no evidence of <br />moisture on the ground surface outside the adit that could reasonably be attributed to seepage <br />from the adit itself. <br />x Contaminated Soil Removal: There is no evidence of removal of contaminated soil from the <br />compressor/vacuum pump shed at the west end of the mill, nor of any preparation to do so. <br />Hazel-A Cleanout: There is no evidence of any cleanout of the Hazel-A adit, or of any <br />preparations to do so. Installation of the doored culvert at the adit entrance has made cleanout <br />more difficult due to degraded access. It has also made it impossible either to verity or refute <br />assertions as to adit condition made by COM, lnc. <br />Water Balance/Effluent Management: There has not, so far as we are aware, been any <br />engineering assessment of the implications of groundwater inflow rates to the Hazel-A adit <br />observed this Spring with regard to required versus available pumping capacities for the seepage <br />sump and the adit pumpback to the tailings pond. Nor has there been any evaluation of the <br />available pond ffeeboard (even if properly lined and anchored) relative to requirements under <br />a reasonable scenario. For example, a week's inflow to the Hazel-A at a mere ten gallons per <br />minute aggregates to more than one hundred thousand (100,000) gallons per week to the <br />tailings pond, exclusive of any accumulations at the pond due to direct infall and surface <br />runoff. At the height of last Spring's wet weather, and for some days thereafter, rapid inflow <br />of water to the Hazel-A adit was observed at and for perhaps fifteen feet back from the <br />entrance, due to fracturing of the overlying rock. From outside the alit mouth, such flow will <br />be impossible to distinguish from flows originating behind the main bulkhead, and will have <br />to be reported as possible discharge violations. The present scheme seems set up for failure. <br />
