We believe it would be useful to consider two other related 
items at the October 5th meeting. In developing guidelines for 
microorganisms in the environment, we think it would be helpful 
to consider the availability and adequacy of guidelines for the 
conduct of greenhouse and other experiments with recombinant DNA 
microorganisms. Guidelines in this area are necessary to 
distinguish experiments conducted in greenhouses from those 
conducted in the open environment. 
Finally, you may wish to discuss the status of the proposed 
spring conference on "Risk Assessment" which is to be jointly 
sponsored by interested Agencies. It is important to make 
progress in the planning of this conference; it may be useful to 
involve the workgroup more directly.
