SUITE 109 <br />P.O. BOX 774018 <br />STEAMBOAT SPRINGS, CO 80477 <br />August 16, 1985 <br /> <br />R~~~1~~~ <br /> <br />~ ~ ~ tN~, <br />Re: Sediment Pond H Inspection <br />Dear Mike: <br />303/879.660 <br />AUG 21 1985 <br />RECLAMIATION DIDVISION <br />In accordance with your request, I inspected the embankment at <br />Sediment Pond H on August 15, 1985. The structure in its current <br />condition is stable. Minor points regarding the structure were noted <br />during the inspection as follows: <br />• Surface crack approximately 50 feet long along the top of <br />the embankment 4 feet from downstream crest - no <br />displacement; depth of crack less than 6 inches <br />• Surface disturbance 25 feet wide at crest of downstream <br />slope - may be caused by equipment during initial <br />construction or clean out; effect insignificant due to <br />substantial top width <br />• Seep approximately 15 feet downstream of downstream toe - <br />from bedrock area below embankment foundation; no effect on <br />structure <br />• Minor rodent holes along upstream face at/near water line <br />no effect due to substantial embankment top width <br />These minor surface features do not adversely effect the structure's <br />stability or integrity. However, Colorado Yampa Coal Company may wish <br />to check these items during the future regular inspections of the <br />structure to determine the need for minor maintenance. <br />If you have any questions regarding this inspection, please contact <br />me. <br />Sincerely, SON D• ST <br />~v..~~a1si~;r o~'Pi <br />ACZ INC. % e , O <br />` ~// ~ •z 16811 Wt ~ <br />l •O <br />LV ~ ~f G~ilO <br />Eldon D.
