September 12, 2011 C -1982 -057 /Seneca II -W Mine SLB <br /> <br /> <br />Number of Partial Inspection this Fiscal Year: 5 <br />Number of Complete Inspections this Fiscal Year: 1 <br /> <br /> Page 4 of 10 <br /> <br />Vegetation between T18 and the Ridgeline Road was visually/qualitatively observed. Cover was good - very few <br />rills or gullies were observed . There was a variety of grasses (wildrye, fescue, wheatgrasses) and forbs and a good <br />amount of sage (some 2 -3’ tall), rose, and chokecherry. Vegetation on the south end of the mining area was <br />thinner and much weedier than in the north. There were sever al successful willow tubelings in the concentrated <br />shrub planting area in the uppermost surge structure of channel PM -1A. <br /> <br />Areas seeded this spring and summer along the Mine Entrance Haul Road and Road A have germinated. There <br />appears to be a good success rate on grasses - ranging from 2 -6” tall. <br /> <br />Nearly all of the Original Permit Area/North Area reclamation was being grazed by cattle. <br /> <br />Weed spraying undertaken at the site earlier this summer appeared to have helped. The thistle population had <br />been knocke d down somewhat, but remains a problem. The operator should continue to spray as late in the season <br />as possible. A few areas that did not appear to have been sprayed were identified - see attached map. There were <br />also heavy weeds in the immediate vicini ty of Pond 017 and Stock Pond T25 that did not appear to have been <br />sprayed . <br /> <br />SLIDES and DAMAGE - Rule 4.12: <br /> The two slumps above T18 have caused gullies where water has surfaced from within the slump. Ditches <br />should be constructed to convey this water o ff of the slide areas and into T18; the ditches should either have rip <br />rap or TRM liner installed. <br /> <br />Work was continuing on the Pond 016A slide area. An excavator and truck were removing sediment from the <br />south end of the pond, near the spillway to Pond 01 6. Sediment from the pond was being placed at the toe of the <br />slope on the northwest side of PM -3, which runs northeast from the pond. The north end of 016A had been <br />cleared of sediment and was being backfilled with material from below the shrub plot. Th e operator indicated that <br />the area below the shrub plot was very wet; they were attempting to excavate low enough to find the source of the <br />water so a drain could be constructed. A representative from NWCC, the geotechnical consultant for the area, was <br />on site on September 13th. <br /> <br />SIGNS AND MARKERS – Rule 4.02: <br /> The mine identification signs, permit boundary markers, topsoil stockpile markers, and stream buffer zone <br />markers were all observed on site. <br /> <br />TOPSOIL – Rule 4.06 Removal 4.06.2; Substitute Materia ls 4.06.4(4); Storage and Protection 4.06.3; <br />Redistribution 4.06.4: <br /> Topsoil had been augmented in several bare areas along the Ridgeline Access Road, Light Use Road LU - <br />1and Roads J and K. Topsoil placement was complete along the reclaimed areas along th e Mine Entrance Haul <br />Road and Road A. The operator indicated that all areas where topsoil has been distributed were seeded. <br /> <br /> <br />
