Colowyo C-1981-019 ~ <br />Pg 2/3 26 July 2005 <br />Hydrologic Balance (cont.): The East Taylor Pond contained water approximately 18" <br />below the weep-hole. The emergency and primary spillways were in good <br />condition. The pond embankment was well vegetated and stable and no erosional <br />problems were noted. <br />- The Taylor Pump Pond contained water above the gated valve but the valve was <br />closed and it was not discharging. The emergency spillway is a riprapped channel <br />with vegetation growing in it. It appeared to be stable at the time of the inspection. <br />The pond embankment was well vegetated and stable with no erosional problems <br />noted. <br />-The Gossard Pond (003A) contained water approximately 6" below the primary <br />spillway. Both the emergency spillway culvert and the secondary emergency <br />spillway culvert appeared to be clear. The pond embankment was well vegetated <br />and stable and no erosional problems were noted. <br />-The Rail Loop Pond contained water approximately 3' below the gated discharge <br />pipe (which was closed). The emergency spillway appeared to be in good <br />condition. The pond embankment was well vegetated and stable and no erosional <br />problems were noted. This pond needs to be cleaned. <br />-The Stoker Siding Pond contained water approximately 4' below the discharge <br />pipe. There was a very small (immeasurable) trickle of a discharge out of the weep- <br />hole. The embankment was well vegetated and stable and there were no erosional <br />problems noted. There were some coal fines at the inlet of the pond but they did not <br />appear to be a problem at this time. <br />-The Gulch A Pond contained water approximately 5' below the discharge pipe. <br />The emergency spillway appeared to be stable at the time of the inspection. The <br />pre-settling sump appeared to be stable. The embankment was well vegetated and <br />stable and there were no erosional problems noted. <br />-The Prospect Pond contained water approximately b' below the discharge pipe. <br />The emergency spillway appeared to be stable at the time of the inspection. The <br />embankment was well vegetated and stable and there were no erosional problems <br />noted. <br />- The Section 16 Pond contained water approximately b' below the discharge pipe <br />and approximately 1' below the weep-hole. The emergency spillway appeared to <br />be stable at the time of the inspection. The embankment was well vegetated and <br />stable and there were no erosional problems noted. <br />Backfilling and Grading: Some backfilling work was being performed at both the East <br />and West Pits. The mine has several variances from contemporaneous reclamation. <br />All of the previously backfilled portions of the East and West Pits appeared to be <br />stable. The open Section 16 Pit was in good condition with no highwall failures noted <br />at the time of the inspection. <br />Topsoil: The operator was stripping topsoil from the Taylor Draw East Fork at the time <br />of the inspection. All of the topsoil on the slop had been removed and they were <br />removing the soil from the bottom of the drainage. The topsoil thickness increased <br />from approximately one-foot at the top of the ridge to more than 18-feet in the <br />drainage bottom. Water is infiltrating from the head of the draw, going underground, <br />
