As previously indicated, EDF can support NIH's objective 
of certifying host-vector systems proposed by industry. 
Certification is more of a categorization than an approval of 
an operating plan and as such does not depend on subsequent 
monitoring to insure compliance. EDF can also support RAC 
establishment of containment guidelines for experiments pro- 
posed by industry. RAC would then lend its expertise to 
facilitate the proper determination of safety levels but not 
give its stamp of approval to a process it cannot control. 
We appreciate the opportunity to submit these comments 
and await RAC's debate on this issue. 
Sincerely
