There are 35 wells in the program, of which 17 monitor the water-table aquifer. One of these latter wells, well 807A, has been damaged more than once as a result of construction activities. It is located in a switchyard under high voltage lines. Previously, the well has been effectively repaired, but the last damage (i.e., breaks in the casing) resulted in obstructions in the well that prevent measuring water levels. The soil around the well was carefully excavated to a depth of 10 feet and casing to that depth was replaced, removing the first obstruction at an approximate depth of 8 feet. However, following that work, a second obstruction was identified at a depth of 60 feet. Attempts to bypass the second obstruction with a measuring tape have been unsuccessful. Any further attempts to clear the well of the second obstruction would require the use of a drill rig, but the high voltage lines of the switchyard preclude ready access. Proper restoration of well 807A would require tempora ry removal of the high voltage lines for repair access, and possible interruption of plant operation. Well 807A, which is 600 feet north of the power block excavation, is not critical to the monitoring program. This area of the unconfined aquifer is adequately monitored by wells 129 and 806B; they are between 807A and the power block, and are within 325 feet of 807A. The attached Table 1 lists the wells in the monitoring program, and Figure 1 shows their locations. Based on the above discussion. Georgia Power Company has decided to seal and abandon well 807A. Sealing will be accomplished per approved site procedures and is scheduled for June 1988. ($ 8803220031 880314 Ifl PDR ADOCK 05000424 P DCD
