Daily opacity readings ranged from to 100%, with a yearly average of 

 37% compared to 21% in 1989. Saskatchewan's opacity standard of 40% was 

 exceeded 2,265 times in 1990, significantly more than 1989' s 768 

 exceedances. Down time for the opacity monitor was 4% as compared to 

 1989' s 6%. Stack gas flow rates ranged from a low of 354 to a high of 

 687 m 3 /second, with an average flow of 590 in 1990 which is close to 

 1989' s 606. Down time for the 12-month period in 1990 was 1%, down 

 considerabley from 29% in 1989. 



Units No. 1 and No. 2 operated with yearly average capacity factors of 

 88.1% and 88.4% respectively, compared to 93.8% and 93.1% in 1989. 

 Totals combining both units were as follows: 



Coal - 3,821,978 Mg in 1990, compared to 4,172,493 in 1989. 

 Oil - 2,102 m 3 in 1990, compared to 1,754 in 1989. 

 Gross Megawatt Hours - 4,574,700 in 1990 compared to 4,851,700

Stack Sampling 



A stack sampling survey, as per Condition 17 of Sask Power's Permit to 



Operate #197R6 was conducted on August 23, 1990. The results of the 



sampling for SO„, NO , and particulates were as follows: 



S0 9 - 3,057 ng/m 3 (@ 3% 0„) in 1990, compared to 2,680 mg/m 3 in 

 1989. 



NO x - 744 mg/m 3 (@ 3% 2 ) in 1990, compared to 712 mg/m 3 in 1989. 



Particulates - 474 kg/hr in 1990, compared to 351 kg/hr in 1989.
