March 18, 2015 C- 1982 - 057 /Seneca II -W Mine JHB <br />006 drainages were visible, though snow covered. No significant concerns could be noted through the snow. T -5 <br />was still partially ice covered and was discharging. No problems were discerned in the 006 -Gulch drainage. <br />Pond 005 was accessible and was discharging. Snow had melted off the embankment but was present on the <br />north facing slope of the pond. Runoff was flowing into the pond at the inlet. Inlet integrity appeared good. <br />Pond 005 was still mostly ice covered, though the ice had thawed around the riser. Discharge measured <br />approximately 0.03 on the staff gauge. The flow was too low for an accurate measurement using the gauge. No <br />paper was in the Steven's recorder. Vegetation upstream of the flume needs to be cleaned out. There is <br />vegetation in the stilling pipe and this pipe is not level. <br />T -22 was functioning well and discharging as designed. T -20 was holding a pool of water and was discharging <br />as designed. Drainage 005 -E1 was flowing with runoff. No signs of breaching of the collection ditches, designed <br />permanent drainages, or pooling water were seen. The stock tanks and drainages appear to be functioning well. <br />The new collection ditch west of T -18 was still snow covered, but water could be heard flowing and observed <br />discharging into culvert PM -15. T -18 was still ice covered but appeared to be functioning well. Drainage 005 - <br />Gulch was inaccessible and still snow covered. Drainage 005-WI was observed through binoculars, with no <br />apparent concerns noted. <br />SCC has replacement flumes stored at the facilities area. Flumes that have rusted, are no longer level or have <br />other problems will be replaced in 2015. <br />T -2 and T -3 were holding full pools of slightly cloudy water and discharging. Both stock tanks were free of ice. <br />Inlets to both of these stock tanks were holding up well. There were no problems on the discharge drainage areas <br />of either T -2 or T -3 stock tanks. The sediment trap on the north side of culvert A -3 is full of sediment but culvert <br />A -3 is flowing freely. This sediment trap will need clean out during regular road maintenance. <br />Pond 16 was still ice covered but was discharging. No problems were noted with pond 16 during this inspection. <br />PM-2, PM -213 and PM -3 drainages had considerable flows. The drainage to culvert J -7 was flowing well too. <br />No new gullies were seen to be forming, flows appeared confined to established drainages or collection ditches. <br />The Spring at PM -2 was flowing well. Culvert under rock crossing was flowing almost at capacity. (Photo 7) <br />The rock retaining wall was stabilizing the channel well. Some pooling of the flow was occurring on the inlet on <br />culvert under the rock crossing. Once water recedes, SCC needs to evaluate the north side of the inlet to culvert <br />under the rock crossing and assure that no cutting into the crossing has occurred. If there has been side cutting, <br />this will need maintenance. <br />ROADS — Rule 4.03, Drainage 4.03.1(4)/4.03.2(4), Surfacing and Maintenance 4.03.1(5) and (6)/4.03.2(5) and <br />(6) <br />Access throughout the site was limited by snow covered roadways and warm temperatures resulting in <br />soft muddy roads. The main access road, access road A to the shop, access to the oil well, access road J to pond <br />016, and access road G were solid enough to traverse by vehicle.
