1. Reduction of replicate samples from six to four panels, which 

 can be accomplished without significant losses in information. 



2. Speciation of algae should be curtailed because these species 

 are more intensively treated within the Rocky Shore Study. 



3 . Asbestos and wood panels should be deployed separately to 

 reduce as much variability as possible in collecting fouling 

 and wood-boring species, respectively. 



4. Depending on the results of the woodborer life histories 

 studies in the next two years, additional research may be 

 required to field verify conclusions drawn from laboratory 

 studies. 



CONCLUSIONS 

 We believe the past program has established an adequate historical 

 base from which future power plant effects can be detected. In addition, 

 proposed studies concerning the temperature tolerance, growth, and 

 fecundity of shipworms will refine our ability to assess any impacts 

 which thermal incursions could have on indigenous and non-native wood- 

 boring species. Data on the rates of destruction of common building 

 materials caused by woodborers will provide an important link between our 

 monitoring studies and the actual concerns of local residents. Finally, 

 resumption of the exposure panel studies prior to three unit operation 

 will provide an update of our present data base and continuity between 

 the preoperational and operational phases of the investigation.
