He has con- cluded that -CCA presents negligible environmental risk. In summary, the material is in agreement with what he told the Commission one month ago. He suggested that the Commission,, for the time being, continue to allow CCA ! treated lumber to be used for structures until a better alternative material be- m s a ailable. The American Wood Preservers Association is working. to develop a Seal of Approval for treate&lumber upon which they will engrave a fish shape that indicates that the entire chemical process has been completed; the fixation process is completed and they are developing a Chrorotrophic Acid Test that en- sures that fixation is complete.. . There is the possibility of a new preservative to be used in lumber 'called AC preserve. He is sending for more information on this. It is touted that this material is the wood that deters rot,- deay and termites without arsenic or chromium, In the future, perhaps plastic lumber will become practical ; at present, it does i not have adequate strength and not available in large sizes to replace a piling. Mr. Gordon'-s suggested is to allow CCA to be used at present but review the sit- uation on a yearly basis.
