Two reportable spills occurred during 1988, April 13 and July 27. 

 Both spills involved the discharge of ash/ash water. The April 13, 

 1988 spill resulted from a failed gasket on ash line "C" by the west 

 side of Ash Lagoon No. 1. Ash/ash water in the amount of 15 cubic 

 meters (nr) was released and all was contained in a small area. 



The 1988 July 27 spill occurred because of an eroded elbow on ash 

 line "C" west of the ash recirculation building. About 250 m 3 of 

 ash/ash water were released. None reached the reservoir. To reduce 

 the occurrence of an ash/ash water spill in the future, two of the 

 three ash lines from the power station and the lagoons were completely 

 changed in the third quarter of 1988. The Poplar River Power Station 

 has also instituted an ash line thickness monitoring program to keep 

 track of the condition of the ash lines. 



Operation of the ash lagoons was similar to 1987. Most of the ash 

 was directed to Ash Lagoon No. 1 during 1988. Ash Lagoon No . 3 was 

 used to a greater extent in 1988. Surcharging continued on Ash Lagoon 

 No . 1 . Monitoring of the surcharge ash will be started in 1989. 



The revegetation project started in 1987 was continued and expanded 

 in 1988. Several species continued to show promise. Testing will 

 continue in 1989. 



Construction 



There was no construction activity during 1988. 



Mining 



Coal mining continued to the west of Girard Creek and will continue in 

 a northwesterly direction in 1989. The South Block infrastructure 

 was developed in 1988, including construction of the causeway cross- 

 ing the East Poplar River. Prairie Coal Limited plans to move the 

 draglines to the South Block by the end of June 1989 to begin mining 

 operations there. Saskatchewan Power Corporation plans to continue 

 dewatering operations at the abandoned mine site to supplement the 

 water supply in Cookson Reservoir.
