All "contaminated" runoff from the site <br />is routed into either the East or West ponds. Runoff is routed along the outside of the site via <br />channels. Seasonal snowfall accumulation has mostly melted off from the site with the <br />exception the north side of buildings and slopes. <br />The ditches surrounding the site were clear of debris and generally in good condition. The <br />outlet pipe between the East and West Ponds mentioned in the 9 -28 -12 inspection has been <br />repaired (see Pic. 1). Finish grading of the ponds, unable to be verified during the 12 -18 -12 <br />inspection, had been completed (see Pic. 2 & Pic. 3) <br />Material from the Coal Waste Pile has been completely removed from the west side of the site <br />and trucked and spread to the top of the refuse pile located along the east side of the site per <br />the determination made by the Division of Mining, Reclamation & Safety (see Pic. 4). <br />The inlet to the east pond was obstructed due to debris pushed near the culvert as a result of <br />snow removal operations during the winter months (see Pic. 5). While obstructed, <br />"contaminated" site runoff cannot circumvent the pond and escape the site due to the existing <br />topography. The north of two drains along the roadway, downstream of the detention ponds, <br />has experienced some erosion as a result of runoff due to snow melt. As a result, runoff from <br />P.O.
