plants considered in the Battelle report utilize 2,000 

 cubic feet per second of water for cooling the condensers, 

 and this increases the temperature of the water thus 

 utilized by 16 degrees Fahrenheit. Major water temperature 

 increases are expected at or near the outfall areas and 

 minor increases would be detectable for soooe distance 

 from the outfall plume, depending upon tidal circulation. 

 Thus temperature of the salt water will become an important 

 variable to consider in the Puget Sound area in the not 



too distant future. 



At this very moment, fisheries agencies are 

 facing problems of thermal pollution in the Columbia River, 

 since increases in water temperature can cause detrimental 

 effects on production of salmon. The Columbia River is 

 slowly becoming marginal for the production of salmonids, 

 and water temperature plays a critical role in this 

 relationship. Hydro impoundments in this area have 

 reduced velocity of flow and have increased surface 

 acreage exposed to solar radiation. Increases in water 

 temperature during the summer months has resulted. 



It is stongly suspected that the synergistic 

 effects of wasted heat from the Hanford complex on sublethal 

 and lethal concentrations of nitrogen gas produce a wholly 

 undesirable situation for migrating salmonids.
