In conclusion, our objectives for the timber study are being met. The untreated timbers have provided 

 the needed database for quantifying wood-loss from site to site and year to year. The longevity of untreated 

 Douglas Fir and Red Oak have been determined, and that for the treated woods continues to be investigated. 

 Chemical treatments deter woodborer attack, but cutting treated timbers exposed unprotected surfaces. Of 

 our test treatments, only creosote was penetrating enough to provide protection to interior wood grain. 

 These data will be used to defme potential power plant impacts on wood-loss in the vicinity of Millstone 

 during three unit operation.
