From the documents reviewed, it appears that the focus of the analyses was the stability of the stack. A global analysis of the Retired Ash Basin Dike does not appear to have been performed. Recommended Action: Previous slope stability analyses for the dike should be reviewed to ensure proper geometry has been used and the weight of the ash stack has been included. If not analyzed, the stability of the dike under the current loading conditions should be evaluated, accounting for existing geometry and piezometric conditions. Topographic surveys, geotechnical explorations, and laboratory testing may be needed to address data gaps. ALL- 2: (Stantec Facility Issue 2) A crack (approximately 35 feet long) was observed along the crest of the East Dike of the Active Ash Basin, with an associated bulge approximately 25 feet down slope along the external side of the dike. Recommended Action: The area should be monitored as part of the monthly inspections; if settlement of the crest or increased width or length of the crack is observed, proper mitigation of the area should be performed. ALL- 3: (Stantec Facility Issue 3) Seepage was observed above the bench of the stability berm on the northern end of the East Dike, near the tie-in with the North Dike. Recommended Action: The locations should be included in the monthly inspections and monitoring program to note any change in flow rate, turbidity, or increase in the saturated area. ALL- 4: (Stantec Facility Issue 4) Seepage was observed along the toe of the stability berms on the East and North Dikes of the Active Ash Basin. These seeps coincide with designed internal drainage of the dikes. Recommended Action: Seepage locations should continue to be monitored to note any changes in flow rate, turbidity, or the presence of new seeps. ALL- 5: (Stantec Facility Issue 5) Seepage was observed at the toe of the Retired Ash Basin along the edge of the coal yard. Recommended Action: This seepage should be included in the monitoring program to note any change in flow rate, seepage area or turbidity. This area, along the edge of the coal yard, does not appear to be included in current periodic inspections of the dam, and should be inspected regularly. Pipe/Outlet Structure Issues: ALL- 6: (Stantec Facility Issue 6) An undocumented pipe (18-inch galvanized steel) was observed near the toe of the Retired Ash Basin dike, along the edge of the coal yard. Recommended Action: The pipe should be video-inspected to determine the inlet location and the condition of the pipe. A survey should be performed to document the location of the pipe, and if necessary a plan to properly abandon the pipe should be implemented. ALL- 7: (Stantec Facility Issue 7) Access to the Retired Ash Basin riser structure is limited; at the time of the inspection the structure was inaccessible because of standing water. The previous independent inspection report (S&ME, 2008) indicates that the intake conduit has been displaced. Recommended Action: Proper access to the riser structure should be provided to allow for periodic inspection and maintenance of the riser structure. The CCTV inspection performed by Stantec on April 15, 2014 did not observe the previously noted displacement. Additional evaluation of the riser structure is recommended. Maintenance Issues: ALL- 8: (Stantec Facility Issue 8) Erosion was observed in the swales located on the stability berm on the Active Ash Basin East Dike. Recommended Action: Provide proper erosion control measures in the swales. ALL- 9: (Stantec Facility Issue 9) No vegetation was present under the coal yard outlet pipes on the external face of the Active Ash Basin East Dike. Recommended Action: Vegetation or other erosion protection should be established under the pipes. ALL- 10: (Stantec Facility Issue 10) Caps were not observed on piezometer riser pipes. Recommended Action: Vented caps should be installed on all piezometers. ALL- 11: (Stantec Facility Issue 11) Observation wells along the external face of the Active Ash Basin East Dike were observed to be missing protective casing. Recommended Action: Surface protection should be provided for active instrumentation. If wells are no longer in use, they should be properly abandoned and the riser pipes removed. ALL- 12: (Stantec Facility Issue 12) Animal burrows were observed along the dikes. Recommended Action: Burrows should be properly backfilled and reseeded. ALL- 13: (Stantec Facility Issue 13) Erosion and steep slopes were observed on the internal face of the Active Ash Basin North Dike near the western end. Recommended Action: Proper slope geometry and drainage should be re-established and erosion protection should be installed. ALL- 14: (Stantec Facility Issue 14) Erosion and sparse vegetation was observed along the western end of the Active Ash Basin North Dike external face. Recommended Action: Erosion should be repaired, vegetation should be re- established, and those areas should be monitored as part of the monthly inspections. ALL- 15: (Stantec Facility Issue 15) Erosion was observed around two culvert pipes under the sluice lines along the Active Ash Basin North Dike. Recommended Action: Proper erosion control measures should be installed. ALL- 16: (Stantec Facility Issue 16) Rutting and depressions were observed along the crest of the Retired Ash Basin dike. Recommended Action: Proper grading and repair should be performed. ALL- 17: (Stantec Facility Issue 17) Trees and brush were observed on the external face of the Retired Ash Basin dike. Recommended Action: Trees and dense brush that prevent visual observations should be removed. ALL- 18: (Stantec Facility Issue 18) Rutting and depressions were observed on the access road near the toe of the Active Ash Basin East Dike. Recommended Action: Proper maintenance should be performed on the access road to repair rutting and depressions. Active Ash Basin Dam (GASTO-061) Outlet Pipe: ALL- 19: (Stantec Pipe Issue 1) A hole in the pipe is located next to a joint approximately 475 feet from the pipe outlet. A circumferential crack is located next to the riser, and it is wider than a hairline crack. Recommended Action: Repair the hole and the circumferential crack. Decant Structure/Riser:  Issues: None. Retired Ash Basin Dam (GASTO-016): Outlet Pipe: Issues: None. Decant Structure/Riser: ALL- 20: (Stantec Pipe Issue 2) Infiltration was observed in a pipe joint of the riser, at a depth of 6.6 feet. Recommended Action: Repair pipe joint. ALL-21: (Stantec Facility Issue 19) Portions of slopes on the Active and Retired Ash Basin dikes were observed to be steeper than designed. In addition, the stability berm of the Active Ash Basin East Dike was observed to be narrower than designed. Recommend Action: Perform topographic survey to confirm geometry. If necessary, re-grade to establish design geometry or verify that stability criteria is acceptable for current configuration. ALL-22: (Stantec Facility Issue 20) Ponded water was observed along the external bench of the Active Ash Basin North Dike. Recommended Action: Proper grading of the bench should be performed.
