Sutherland and Karlson 1977), these factors can be standardized to allow comparisons between communities 

 that develop at different sites, or in different seasons. Several environmental monitoring programs have 

 used exposure panels to assess effects of thermal effluents (Cory 1967; Frame 1968; Cory and Nauman 

 1969; Nauman and Cory 1969; Hillman 1975, 1977; Young and Frame 1976; NAI 1979; Maciolek- Blake 

 et al. 1981; Osman et al. 1981; NUSCo 1982). Our Exposure Panel Program objectives are: 



1. to monitor the abundance of marine woodborers at five sites in the Millstone Point area, 



2. to quantify the loss of wood associated with the presence of woodborer populations in the vicinity 

 of MNPS, 



3. to monitor the dispersal of Teredo bartschi in terms of distance from the Millstone Quarry, and, 



4. to monitor the abundance of prevalent fouling organisms, and to investigate their relationship to 

 woodborer abundances in the Millstone Point area. 



To achieve these objectives, three separate studies were conducted. The first (Exposure Panel Study) 

 used exposure panels to monitor the abundance of fouling and wood-boring species, as well as the 

 associated wood-loss. The second study (Distribution Study of Teredo navalis and Teredo bartschi) used 

 exposure panels deployed in close proximity to the MNPS discharge to monitor the distribution of 

 shipworms, in relation to the thermal effluent. The third study (Timber Study) used commonly available 

 dock building materials to quantify wood-loss. 



The purpose of this report is to provide a summary of results from all Exposure Panel Program 

 studies performed during 2-unit operation. Space limitations required considerable condensation of infor- 

 mation; more detailed data are included in Appendix EP I.
