its Resource Contingency Program, Bonneville applied resource-specific 

 environmental costs which were included in the cost-effectiveness tests to which 

 all prospective resources were subjected. In addition, non-price environmental 

 factors are considered during resource selection processes to assure that the fijll 

 range of environmental effects is taken into account. 



Bonneville has focused on the environmental costs associated with plant 

 operations. Our estimates do not reflect the environmental costs associated with 

 the entire fuel cycle The U.S. Department of Energy is now conducting a study of 

 fuel cycle environmental costs which we hope to rely on to augment our estimates
