The demonstration unit was added to Unit No. 1 at the Poplar River Power Station. 



Constnjction occurred during the first eight months of 1990 and the system was 

 commissioned in September 1990. initial testing of the LIFAC process took place from 

 late October 1990 to the first week of December 1990. 



Extensive testing of the LIFAC process took place in the first half of 1991, more 

 specifically from Februarys, 1991 to April 19, 1991 and then from June 16, 1991 to July 

 3, 1991. Following these periods there was very little LIFAC testing was done. There 

 is no scheduled testing of LIFAC planned for 1992. 



2.5 Scribner Dam 



In July 1991, the "Release Management Procedure of Scribner Dam" was updated to 

 include oil and grease testing. In addition to the routine testing for conductivity and pH, 

 a visible check for oil and grease will be done and a sample will be taken for oil and 

 grease analysis. Oil and grease analysis was added to make sure no petroleum-based 

 products are added to the reservoir. 



In 1991, there were twelve releases from Scribner Dam as compared to only three in 

 1990. This increase can largely be accounted for by the above average rains from April 

 1991 to July 1991. In the last quarter of 1991 , excess water from a domestic well was 

 directed to Scribner Dam and accounts for the releases during this time. Table 2.3 

 provides a summary of the testing completed during 1991 for Scribner Dam. On each 

 occasion, the contents were released to the reservoir.
