Dear Dr. Fredrickson: 
This letter is to support the Eh coli K12/P1 Recommendation (made by 
the RAC on 6-7 September 1979) as outlined in your Decision Document/Environ- 
ment Impact Assessment published in Federal Register 44(232:69234-69246, of 
30 November 1979. 
After careful consideration of the pertinent data, I strongly support 
the passage of the Eh coli K12/P1 Recommendation without reservation. It is 
clear that the use of Eh coli K12 strains in recombinant DNA experiments pro- 
vides distinct and inherent safety to the people and our environment. Passage 
of the Recommendation would allow an immediate surge in medical research, 
which could have profound impact upon the time required for the achievement 
of new and major medical advancements. To deny the passage of the Recommendation 
would, without purpose and with considerable unnecessary expense, continue to 
limit progress in experimental medicine in this country, which would create 
an injustice to future health care developments for people of the United 
States of America. 
Again, I give full support for the urgent passage of the Eh coli K12/P1 
Recommendation . 
Very truly yours 
E ,D .
