Total suspended particulate concentrations for 1992 obtained from SPC's monitor exceeded 



Saskatchewan's 24-hour standard of 120 ng/m^on three separate occasions: April 12th (246.4 

 M-g/m^), April 30th (318.6 ^ig/m^), and May 8 (363.6 \ig/m^). In all cases, the prevailing wind direction 

 eliminated the power station as a possible influence. The geometric mean for the high-volume air 

 sampler for 1 992 was 23.8 ^ig/m^. 



3.6 Quality Control 

 3.6.1 Streamflow 



To test the quality of streamflow calculations made by the U.S. Geological Survey (USGS) and 

 Environment Canada (EC), similar measurements were made on the East Poplar River at the 

 International Boundary on June 17, 1992 by personnel from both agencies. The discharges shown 

 in Table 3.5 agree within measurement error

3.6.2 Water Quality 



Quality-control sampling was carried out at the East Poplar River at the Intemational Boundary on 

 July 15, 1992. Participating agencies included in the U.S. Geological Survey Environment Canada, 

 Saskatchewan Environment and Resource Management, and SaskPower Corporation.
