All of these ponds were dry. All pond embankments, inlets and discharge structures were stable and no problems were noted at any of these sediment pond locations. The Colorado River is still flowing lower than normal due to recent dry conditions. The upper stretches of Coal Creek were damp and showed evidence of flowing water(Photo No. 1). The rain gauge located along Coal Creek access road indicated a trace of precipitation fell(.07 inches)from the storm earlier in the morning. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization; Placement: The CRDA-I and CRDA-2 waste piles were inspected and both waste piles appeared to be stable. Overall the reclamation looks good at both of these refuse disposal sites.The lower terrace drains and diversion ditches at CRDA-I and CRDA-2 were inspected and found to be stable and dry. There were no areas of instability or erosion identified at either of these refuse disposal areas and no problems were noted. CRDA-I has good vegetation establishment(Photo No. 2). The vegetation reestablishment is more sparse on CRDA-2 as seen in Photo No. 3. Number of Partial Inspection this Fiscal Year: 1 Number of Complete Inspections this Fiscal Year: 0 Page 2 of 5
