Arness-McGriffin & Coal Gulch; p~. 2 <br />Runoff from the upper reclaimed area at Coal Gulch is largely contained in a depression <br />on the reclaimed area. This depression was holding water /cattails and is effective in <br />surface water runoff control here. There is a for sale sign posted for this area directly off <br />highway 160. Soil stockpiles and various landscaping materials the property owner has <br />maintained here at the Coal Gulch entrance of highway 160 the past few years are now <br />gone, and almost al] former abandoned equipment, junk, has also been removed. A few <br />metal gas cylinders remain. There are a few large erosion gullies on soil replacement on <br />the south to southwest facing slope at Coal Gulch which appear to have worsened since <br />EY 2000. I believe this erosion is on the former coal waste pile location, and downslope <br />from the waste pile. <br />There is limited soil replacement and vegetation success throughout the reclaimed areas, <br />but some perennial cool season grasses have established. <br />The Arness-McGriffin Mine has not changed remarkably since our EY 2000 evaluation. <br />The former access road to the mine is used frequently by the public to access the Perin <br />State Wildlife Area above the mine. The public also uses the backfilled portal slope as a <br />backdrop for target shooting. There are some severe erosion gullies adjacent to the access <br />road. As noted above, this site is still contributing surface water runoff and sediment to <br />the Coal Gulch Mine reclaimed area below, principally from one runoff location, causing <br />minor erosion and sedimentation on the coal Gulch Mine reclamation, and resulting in a <br />minor offsite (hydrology) impact to a land resource. <br />Please address any questions concerning this evaluation report to Henry Austin at <br />haustinC~osmre.QOV or to (303) 844-1400 X1466. <br />
