On October 22, 1985 approximately 90 m-^ of ash recirculation water and 

 some ash spilled adjacent to the ash recirculation pumphouse. The 

 pumphouse is located at the northwest corner of the polishing pond. Most 

 of the spilled water flowed into the pumphouse sumps which discharge to 

 the ash lagoons. The remaining spill liquid was contained in the 

 Immediate vicinity. Cleanup procedures were implemented and no spill 

 materials entered Cookson Reservoir. 



On December 1, 1985 approximately 2 m^ of ash and an unknown quantity of 

 ash recirculation water spilled near the sewage holding pond. Reliable 

 evaluation of the spill volume was not possible due to adverse weather 

 conditions and snow cover. For the same reasons, effective clean-up was 

 not practical. However, the spill materials are contained upstream of the 

 drainage ditch main control structure. The ash will be removed once 

 weather conditions permit. Ash recirculation water from the spill will be 

 monitored prior to release to Cookson Reservoir. 



Construction 



A fourth ash recirculation water pump was installed in the ash 

 recirculation pumphouse improving ash handling reliability. Supplemental 

 quantities of reservoir water for ash sluicing, often necessary during 

 recirculation pump failure, will be reduced. This will help maintain a 

 controlled ash lagoon water balance.
