NOV- ~r95 MON 6:35 PM TESS~CT PRODUCTIONS FAX NO, 3479713 r P, 3 <br />z <br />Game Fence: Fencing remains rolled on-site, down-slope from the dam crost. 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-harming of the slope just south of the former trailer parking area has <br />been acwmplished; the berm does not appear to have been compacted. <br />.Han, 1 A Portal Bac 11; It was impossible to verify completion of the required fifteen-foot <br />horizontal backfill of the Hazel A edit 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 beers no compaction of back-fill, <br />substantial settling and outwash can be expected during the Spring tneltoff. <br />der 1?ump-Back $ycrsm: Due to the btockod access noted above, it was impossible <br />rfl ascertain status of this system, or water levels behind the bulkhead in the Haze) 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 edit entrance. There was no evidence of <br />moisture on the ground surface outside the edit that could reasonably be attributed to seepage <br />from the edit itself. <br />* C'ontAm;nAtrd foil Removal: There is no evidence of removal Of contaminated soil tiom the <br />compressorJvacuum 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 clesnout of the Hazel-A edit, or of any <br />preparations to do so. Installation of the doored culvert at the edit entrance bas made cleanout <br />more difficult due to degraded access. It has also made it impossible either to verify or refute <br />assertions as to edit condition made by CUM, Inc. <br />Water •Balance/Effluent Manacemmt: There has not, so far as we are aware, lien any <br />engineering assessme~ of the implications of groundwater inflow rates to the Hazel-A alit <br />observed this Spring with rrgard to required versus available pumping capaaties for the seepage <br />sump and the edit pumpback to the tailings pond. Nor has there been any evaluation of the <br />available pond freeboard (even if properly lined and anchored) relative to requiremerns 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 weak to the <br />tailings pond, exclusive of any aecumuhuions 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 W the Haul-A edit was observed at and for perhaps fiReen feet back from the <br />entrance, due to fracturing of the overlying rock. From outside the edit mouth,, such flow will <br />be impossible to distinguish from flows originating behind the main bulkhead, and will have <br />to be repeated as possible discharge violations, The presets scheme seems set up for failure. <br />
