The sulphur content of the No. 2 fuel oil consumed at the Poplar 

 River Power Station varied from 0.06 to 0.08 percent in 1984. 



On May 16, 1984 approximately 3 200 litres of Ferri-Floc solution 

 (50 percent Fe2 (804)3) were spilled as a result of a drain pipe 

 failure on a holding tank. The spill was contained upstream of the 

 first spill containment structure in the ditch south of the plant. 

 Spill cleanup procedures were implemented and none of the spill 

 materials entered Cookson Reservoir. 



Construction 



Concrete and stoplog overflow structures were constructed between No. 

 1 and No. 2 ash lagoons and between No. 2 ash lagoon and the polish- 

 ing pond. The structures provide better ash lagoon water level con- 

 trol and improve the lagoon management system. A waste water pond, 

 overflowing into the polishing pond, was created at the northwest 

 corner of No. 1 ash lagoon to facilitate the revised lagoon operating 

 regime. The work was completed in October 1984. 



An online ball type recirculation condenser cleaning system was pur- 

 chased, installed on Unit 2 and commissioned in October 1984. The 

 cleaning system, using charges of plain sponge rubber balls and in- 

 termittent charges of ceramic coated balls, mechanically removes 

 scale and marine growth from the circulating water side of the con- 

 denser tubes. The balls are continuously injected into the condenser 

 cooling water inlet, circulated through the condenser tubes, col- 

 lected by a screen in the condenser cooling water outlet, and pumped 

 back to the inlet. Scale inhibitor chemical dosing at the condenser 

 inlet was discontinued.
