remaining in the pond during the summer at a fairly high level contributed to the saturation of the <br />embankment to some degree. This spring has been abnormally dry and very warm and windy. I <br />feel this has had a very rapid and severe drying effect on the embankment, causing the large <br />shrinkage cracks in the embankment. <br />Because the cracks are pazallel with the axis of the embankment and the cracks are dry to the <br />bottom, I do not feel that the embankment is prone to any imminent failure. These cracks must be <br />filled and compacted as soon as practicable and then monitored closely to help confirm their <br />nature or see if other forces are at work. <br />[ would Gke to suggest the following course of action: <br />Fill the cracks and compact the soil in lifts with a digging bar in the crack as much as <br />practicable. <br />2. Morutor the embankment at a minimum on a monthly basis for eighteen months and after <br />any significant precipitation event. Monthly monitoring can lapse after the ground freezes <br />in the winter. <br />If unusual events or movements are noted, the magnitude and nature will be noted and a <br />course of action will taken to ensure the stability of the embankment. <br />4. Reports of all monitoring and actions will be included with the Quarterly Sediment Pond <br />Inspection Report. <br />This plan should be effective in ensuring the stability of the embankment structure and relieve any <br />wont' of failure. The relative depth of the main spillway to the embankment and the past <br />performance of the embankment in terms of retaining water should give an added measure of <br />safety during this monitoring period. <br />If after December of 1997 the embankment has remained stable this matter may be considered <br />resolved. <br />If you have any questions as to this plan or course of action, please feel free to contact me at the <br />Mine at Ext. 223. <br />
