In 1990, Sask Power assumed responsibility for the dewatering operations 

 at the abandoned west block mine site. Water from this pumping is used 

 to supplement the water supply in the Cookson Reservoir and to provide 

 local domestic requirements. 



Construction 



Construction of a demonstration scale LIFAC flue gas desulfurization unit 

 was completed on Poplar River's Unit No. 1 in the third quarter of 1990. 

 The system was commissioned in September 1990 and extensive testing was 

 done in the last quarter of 1990. Results of testing have been encourag- 

 ing. Further testing is planned in 1991. 



In 1990, four pumpwells and connecting pipeline were added to the "Soil 

 Salinity Project South of Morrison Dam". These pumpwells were placed on 

 the west side of the East Poplar River. Construction was completed in 

 October 1990. By the end of 1990, two pumps were in service. 



Mining 



During 1990, Prairie Coal Limited provided coal to the Poplar River Power 

 Station from the south block mine site located east of Coronach, Saskat- 

 chewan. Reclamation of the mined area at the west block mine site con- 

 tinued in 1990 and should be complete in 1992. 



The mineable coal supply at the south block mine site is limited to three 

 to four more years. As a result, Prairie Coal Limited plans to relocate 

 mining in 1994 to the north block mine area located north of Coronach, 

 Saskatchewan. Pre-mine development of the north block mine is scheduled 

 for 1992. The overview of the three mining areas is provided by the map 

 in Figure 4 .
