has been set back at least a year. Dr. Kuehl and our other colleagues 
have not even attempted to use recombinant DNA techniques in their 
research because of the lack of a P3 facility at Virginia, in spite of 
the importance these techniques would have for their research programs. 
The proposed revised Guidelines are a consevative step in 
relaxing the requirements for physical containment for recombinant DNA 
research. However adoption of these revised Guidelines will serve the 
dual purpose of continuing to greatly minimize the possible risks of 
recombinant DNA research, while at the same time providing conditions 
which will permit the realization of the huge benefits which will derive 
from this technique.
