3.5 Air Quality 



SaskPower's ambient SO2 monitoring for 2005 recorded no values greater than Saskatchewan 

 Environment's one-hour average standard of 0.17 ppm and the 24-hour average standard of 0.06 ppm. 

 The ambient SO2 monitor was replaced in January 2001 which has greatly improved the availability of 

 this information. The 2005 geometric mean for the high-volume suspended-particulate sampler was 

 14.5/ig/m^ and 2005 was the fourteenth consecutive year of below-average standard particulate 

 readings. 



3.6 Quality Control 



3.6.1 Streamflow 



Current-meter discharge measurements were made at the East Poplar River at International Boundary 

 site on September 6, 2005 by personnel from the U.S. Geological Survey (USGS) and Environment 

 Canada (EC) to confirm streamflow measurement comparability. Data from the two current-meter 

 discharge measurements are available in Table 3.6.

3.6.2 Water Quality 



Quality-control sampling was not performed in 2005 at the East Poplar River at International Boundary 

 due to suspension in collection of surface-water-quality samples by Environment Canada.
