The Saskatchewan Power Corporation intends to review and implement 

 the recommendations during 1989. The freeboard requirements were 

 not exceeced during 1988. The Saskatchewan Power Corporation con- 

 tinues to experiment with the surcharging of dry ash into the lagoons. 

 The experimental program began in 1987 to determine suitable types 

 of vegetation for the exposed ash continued in 1988. Three species 

 of grass have shown good results and will be further tested in 1989. 



The Saskatchewan Power Corporation has, since May 1983, analyzed 

 filtered ash lagoon water samples to obtain appropriate information 

 on potential leachate quality. Generally, the water quality data 

 continue to show increases in the ash and polishing lagoons for 

 sodium, potassium, sulphate, fluoride, boron, and molybdenum; and 

 continued variability in the levels of uranium. The changes are to 

 be expected in a closed system of this type.
